Engineering menu in Xiaomi phones. Xiaomi engineering menu How to enter “im”

Almost all phones experience software glitches, the source of which may be in the firmware. To identify them and determine the type of failure, there is a special service menu through which you can test each module in the phone and identify the essence of the problem.

In this article, we will tell you what the xiaomi engineering menu is, login methods, as well as the main functions that may be useful to you.

What is the engineering menu and main functions

These are hidden smartphone settings aimed at testing and correcting errors. These settings are not available in the regular menu, because... inexperienced users can mess up the correctly set parameters, after which the phone may stop ringing, the connection may be lost, etc. Therefore, be very careful not to harm the system.

The engineering menu on the xiaomi redmi 3 phone performs the following functions:

  • Setting the sound in the main speaker;
  • Setting the sound in the conversational speaker;
  • Microphone settings;
  • Setting up networks;
  • Camera setup;
  • Testing GPS operation;
  • IMEI repair;
  • Ability to optimize the system for less battery consumption.

These are not all functions, but rather the main ones that are in greatest demand.

How to enter the engineering menu

Let's look at ways to enter the engineering menu using the example of Xiaomi Redmi note 3 pro. There are only two standard methods. The third option is through applications, which is worth using if standard methods do not work.

Through settings

Note that this method is universal; it is also suitable for Xiaomi redmi 3s. So, let's go to the smartphone settings. Scroll down and tap on “About phone”. We look for the line “Kernel version” and slowly click on it three times. Perhaps the message “You only have to press two more times” will appear at the bottom. In the same way, slowly press two more times.

The “secret settings” look like this (depending on the phone, the view may differ slightly):

Using a special code

Open the dialer and dial the code *#*#6484#*#*. The same thing will appear as above in the screenshot. This code should be suitable for all Xiaomi devices. If nothing happens when you dial this combination, you should try the following codes: *#*#3646633#*#* or *#*#4636#*#*.

On some other models, the engineering menu looks like this:

If you can’t open the engineering menu

If Xiaomi redmi note 3 pro does not enter the engineering menu, then you should use alternative login methods, namely special software. Let's look at two programs that will help you: MTK Engineering and MobileUncle Tools. You can find many more similar applications on your own.

MTK Engineering is a fast and convenient program, it looks like this:

In the Android Testing section there are Android settings, namely:

  • Phone information;
  • Battery information;
  • Usage statistics;
  • Wi-Fi information.

We need the MTK Engineer Mode item - this is the engineering menu itself. The appearance may be slightly different, but the essence will not change.

MobileUncle Tools is a more powerful program than the previous one, in that it additionally allows you to perform many other operations with the system, however, only for devices with MTK processors, which are not found in all Xiaomi devices.

To get started, you need to click “Engineering Mode” and then select “Engineering Menu (MTK)”. It is worth adding that this program requires root rights. Currently, this program has been removed from the Play Market, but it is not difficult to find on the Internet. Since this application is developed by a Chinese author, you may encounter an English or Chinese version.

Conclusion and translation of functions

Finally, we would like to caution you to be careful with your many system settings. If you need to repair or check any module in your phone, you should not immediately change the parameters of the engineering menu yourself; it is better to first look for instructions on our website or on the Internet specifically for your case. For convenience, we have translated all functions (the Xiaomi Redmi Three smartphone was taken as an example).

In order for developers and testers of software and mobile devices to obtain some system information and debug smartphone functions, the Android OS contains some hidden features. Among them are connecting to a PC in developer mode, viewing detailed information about networks and hardware, etc. One of the tools for this is the engineering menu.

The engineering menu is a special settings menu that contains tools for testing and calibrating smartphone hardware. By default it is hidden, and in order to get into it, you must perform a certain procedure. The appearance of the engineering menu differs on different smartphones, depending on the manufacturer and SoC model. The customization options will also be different.

There are several ways to enter the engineering menu, which differ depending on the smartphone manufacturer and chipset model. You can first try entering one of the codes in the dialer application:

  • *#*#3646633#*#* - smartphones with
  • *#*#6484#*#* - some smartphones with Qualcomm;
  • *#*#54298#*#* - some smartphones with MediaTek;
  • *#0*# - some Samsung smartphones;
  • *#*#7378423#*#* - some Sony smartphones;
  • *#*#4636#*#* - on some devices opens only the network menu;
  • *#*#2846579#*#* - some Huawei devices.

If none of the codes help, on your smartphone with MediaTek you should install the program “Launch MTK Engineering Menu” from the market. On Xiaomi devices, you can enter the menu by going to “Settings”, selecting “About phone” and then clicking the “Kernel version” line five times in a row.

What can be configured on a smartphone in the engineering menu

The engineering menu differs on different platforms; in many cases, it only allows you to test some parameters. On Xiaomi Redmi Note 3 Pro and Note 4X, built on Qualcomm chips, the engineering menu allows you to test various functions. These include the screen, sensor, sensors, cameras, sound and microphone, communications, battery, navigation, etc. There is no way to change anything, you can only find out if everything is working correctly.

There are much richer opportunities on the MediaTek platform. In Oukitel U7 Plus (MT6737 chipset), the engineering menu allows you to configure network, sound, communication modules, and other modules. On Redmi Note 2 with MTK Helio X10, the menu was identical, and on other devices with MTK it is not particularly different. We will use his example to describe the possibilities.

Telephony tab

This section is responsible for setting up a cellular modem. Here, interesting possibilities are provided by the BandMode, Network Selecting and GPRS options.

BandMode

In this menu, you can select communication standards that will be active on the phone when connecting to mobile networks. In the menu item, you can select frequency ranges for each SIM card; if there are two SIM cards, the full list is usually available only on the main one (usually the first one). Once you know exactly which frequencies your operator uses in the region, you can uncheck all the others. This will slightly increase battery life due to the fact that the device will not search for operator towers in these ranges, wasting extra energy on scanning the airwaves.

Sometimes some communication standards (especially LTE) are supported at the chipset and core level, but are disabled in the firmware. By checking the box next to them, you can activate support for these networks. It is worth warning that it does not work everywhere: on the same Redmi Note 2 (Chinese version) TDD-LTE was enabled in this way, but on Oukitel U7 Plus these items are not activated.

Network Selecting

The name speaks for itself: this item is also responsible for selecting networks. Only in this case the user can choose which types of networks to use. The goal is the same as in the previous paragraph: to reduce the load on the cellular modem, thereby reducing battery consumption. You can choose to work only in 2G, 3G, 4G, or combine several standards.

If your operator does not have 3G or 4G at all, these items can be disabled so that the smartphone does not constantly try to search for LTE networks, thereby speeding up battery drain. You can also disable 3G and 4G if you need constant communication (for example, for correspondence over the Internet), but traffic is limited and uncontrolled use of WCDMA and LTE by background processes can quickly waste it.

GPRS

Despite the name, this item is not interesting because of the GPRS communication settings, which many people no longer need, and it is not recommended for “mere mortals” to change the settings themselves. The main feature is the ability to record the IMEI of the smartphone. In the appropriate item, you can enter the device identification number and click Write to save it.

The ability to write IMEI is often required after an unsuccessful flashing, when it “flies” and the device cannot register in the operator’s network. By copying this code from the smartphone box, you can restore functionality. Attention! illegally changing the IMEI of a smartphone in many countries (including Russia, Ukraine) is a crime! In addition, by rewriting this code to a random one belonging to another subscriber of your operator, communication problems may occur due to a hardware conflict. Therefore, we recommend that you always keep the box or sticker with IMEI in case of unsuccessful firmware. After all, on devices with a non-removable cover, this identifier is not written under the battery.

Connectivity tab

In this tab, functions for testing and fine-tuning the Bluetooth module, radio receiver and Wi-Fi are available. The vast majority of users have nothing to do here, since there are no settings interesting for a layman, but it’s easy to disrupt the normal operation of Bluetooth by entering something wrong.

Hardware Testing Tab

This settings item in the engineering menu is responsible for the hardware configuration. The Audio and TouchScreen items are of interest to users. The latter contains HandWriting and MultiTouch items. It’s easy to guess what these parameters are responsible for.

Using the first one, you can check the clarity of the touchscreen response and check for the presence of “blind spots”. This menu is especially useful when buying a smartphone, in particular, without a warranty. The second point allows you to do the same, but with the participation of several fingers. With it you can test how well the smartphone processes gestures of several fingers simultaneously.

Audio

It is this treasured item that is needed by those who are looking for how to increase the volume in the engineering menu. The top items allow you to control the volume of the device and are responsible for different modes.

Normal Mode is a mode for normal use, with music or video sounds output to the music speaker. Headset Mode is responsible for controlling the volume in the headphones. LoudSpeaker mode allows you to adjust the conversation volume when using the speakerphone. The last item is a combined one; it is responsible for speakerphone when headphones are connected. In order to change the sound in the engineering menu, you need to select which device you want to configure.

  • Sip - settings for Internet telephony;
  • Mic - microphone sensitivity
  • Sph - conversational speaker;
  • Sph2 - second earpiece (a rare beast among smartphones);
  • Sid - after changing this parameter, an echo of your voice may appear during a conversation, so you do not need to touch it;
  • Media - a multimedia speaker, what most people need.

In order to adjust the volume, you need to go to the required mode (for the volume of a multimedia speaker this is Normal Mode), select the Media item and set the volume value in the specified range.

The Level parameter is responsible for the volume value set by the rocker at each division. Level 0 is the minimum value (one division), the highest Level is all divisions, on Oukitel U7 Plus it is 14, on other smartphones it may differ. The value can range from 0 (speaker silent) to 255 (full volume). There is no particular point in changing the value, but if after a certain division it seems to you that the sound suddenly becomes much quieter, you can increase the values ​​​​for this division (and lower levels) by a couple of units. The main thing is that the conditional Level 6 does not turn out to be louder than Level 7 due to the value being too high.

But to increase the maximum volume in general, you need to change the value in the Max Vol item. The maximum level corresponds to 160, but manufacturers often set it lower (on the tested device it was 128). By setting the number higher, the volume will increase, but there may also be side effects such as gurgling, noises and wheezing. The optimal value should be selected using the scientific method: increase the value by a few units, save, check the sound on video or music, and if everything is fine, increase it further.

Conclusion

It’s worth repeating once again that the engineering menu is different on different smartphones. What is available on the MediaTek platform cannot be done on Qualcomm. Codes for entering hidden settings may also not be suitable in some cases; we cannot guarantee their 100% functionality. In addition, everything you do with your smartphone is done at your own peril and risk, since incorrect settings can affect its performance. In such cases, only a general reset or flashing will help. So if you really want to experiment with settings whose meaning you don’t fully understand, it’s advisable to take screenshots before doing so, so that if something happens, you can enter the factory values.

Xiaomi smartphones have a wide variety of settings, ranging from customization and themes to all kinds of firmware and launchers. In this article we will tell you what the engineering menu is in Xiaomi smartphones, how to enable it and configure various parameters there.

What is the engineering menu in MIUI

The Engineering Menu is a built-in feature in Xiaomi smartphones that allows MIUI users to run a hardware check on their devices. This is to ensure that all hardware components are working as expected. For example, in the engineering menu you can check for dead pixels on the display, adjust the volume, and also calibrate the operation of various sensors. The advantages of this mode are as follows:

  • Easy to use
  • Works on all Xiaomi phones: Redmi and Mi
  • No external hardware components required
  • You can avoid service centers and repair everything yourself

How to get to the engineering menu on Xiaomi

To enter this mode, you just need to open the standard “Phone” application and use the touch keyboard to enter the following combination: *#*#6484#*#* . This should work in most cases. If your phone doesn't respond, try these combinations.

  • *#*#3646633#*#*
  • *#*#4636#*#*

If this doesn't work, try going to Settings > About the device and click on the kernel version several times in a row. Do this until the menu opens.

Great, you've reached the menu, now we'll tell you about the main features of this utility. Below is how to check your Mi smartphone and how to fix what is not working properly.

How to run a hardware test in the engineering menu

In this menu you will see an item Automatic Test. Click on it, the automatic test will take you through each test of each component separately, including testing sensors, volume, cameras, vibration motor, Bluetooth, Wi-Fi, touch screen, etc., even for simple things like LED indicator and check buttons

When you click on the item Single Item Test(Checking One Item) will show you the names of all the hardware components of the device. If you are having problems with a specific component, such as the speaker and volume, you can select this option and calibrate the setting.

For example, click "WLAN" if you want to test your Wi-Fi module, click "Gyroscope" to test the gyroscope capabilities. Likewise, you can test any hardware component, one at a time, using Single Item Test.

Button Test Report will show you detailed iron test results. This way you can determine if any hardware components are faulty or broken. The test report indicates the failed component as "FAIL" and the functioning component as "PASS". If any test fails, it says "NOT TEST".

SW and WH Version- Software and Hardware Version provides all the information about the version of device software currently running on the device. As well as all the hardware version information along with IMEI numbers if you need to know this information.

Device View contains information about the processor, display panel, battery, Bluetooth and other things along with information about the manufacturers of these components. All this information can also be used to check whether your device is original or counterfeit.

It is worth noting that the engineering menu works on all Xiaomi devices and is a universal way to check equipment for originality and performance.

To begin with, I want to explain the purpose of the article: help in solving the “jambs” that I encountered myself. Primarily intended for owners of the Chinese version with a firmware modem.
An explanation is needed here. There are currently 3 versions of Redmi Note 2 on the market:
1) European (with European WCDMA 3G and FDD-LTE)
2) Chinese (with Chinese TD-SCDMA 3G and TDD-LTE)
3) Chinese with a firmware modem (simultaneously with European and Chinese communication standards) - my option.

Introduction(or why Redmi Note 2)

This summer the board in my Xperia ZL died untimely (not without my participation). Without thinking twice, I decided to get a replacement device. But, since the ZL itself was quite problematic: I visited the service center 3 times in a row last fall and broke down in less than six months - and for a number of other reasons, I decided not to contact Sony anymore.
I had long heard about Xiaomi, their quality and support, but until 2015 they only released relatively expensive devices, and I didn’t want to spend much. That's why I'm so excited about the Redmi Note 2.
If you are faced with a question about the reason why I took the Chinese version with a firmware modem, the answer is the same: price. It cost as much as $20 less than the European version, and the differences were minimal.

Packaging and equipment

The principle of Xiaomi packaging is efficiency, it looks like this: a cardboard box in which the instructions, warranty card, battery, charger and USB cable are hidden. There were no frills in the form of headphones/OTG or protective film.
But, I must say, the seller made a fuss and put an adapter from a plug with a rectangular cross-section of pins to a Russian one with a round one.
Also, the parcel was sent by Russian Post through Finnish Post, and the wrapper made of several layers of foamed polyethylene withstood everything and even retained the presentation of the box. Thanks again to the seller.

Appearance

The phone case is a classic candy bar, “brick” with a silver “MI” inscription at the bottom of the cover. I am a simple person: I see a “brick” - I think “smartphone”, I see curves and patterns - I think “installation”.
The thickness of the case is 6.2 mm at the edges, 8 mm in the middle, the largest value is observed on the camera - 8.6 mm. Width: 76.3, with buttons - 76.6. Unfortunately, the length of the caliper was not enough, but using its ruler (it is longer than the maximum width of the jaws due to the fastening), it turned out to be about 151.8-152 by eye.
If you want to know how this smartphone fits in your hand, take the ASUS ZenFone 2 ZE551ML - its “twin” brother Note 2 differs only in that it is 2 mm thicker and in the location of the buttons.
It should be taken into account that despite the thin plastic of the lid, the case is quite durable, I managed to drop it on the concrete floor without any special consequences. Also, in this vein, I would like to highlight the slightly protruding “edge” of the display, which takes the blow when dropped on flat surfaces.
Three physical touch buttons (from left to right: Menu, Home, Back) are located below the screen, conveniently highlighted in red and backlit. On the right side there are silver power and volume buttons, USB is at the bottom, and on the top there is a 3.5 connector and an IrDA window (yes, you didn’t think so, a real infrared adapter). Also, on the front panel you can see the camera and telephone speaker, but you cannot (because they are hidden) - light sensors, proximity sensors and a signal LED. On the lid, according to tradition, there is a camera, flash and rear speaker grille. A nice little detail: under the grille there is a small “bump” so that the speaker is not muffled when the smartphone is lying with the display up.

Characteristics

Redmi Note 2 became one of the first owners of the new mid-range chipset from MTK, Helio x10, the successor to the 2014 champion, MT6595, with 8 energy-saving Cortex A53 cores operating at 2/2.2 GHz for the Standard/Prime version and GPU PowerVr 6200. Also the device has 16GB of NAND memory (there is also an option with 32GB), of which 12 are available to the user, and 2GB of LPDDR3 RAM, 1 of which is usually eaten up by the system.
Thanks to this configuration, the device provides 46+ thousand points in Antutu.

Synthetic test results









The latest version of the system at the time of writing this review is Android 5.0.2 in the proprietary MIUI shell, which has its pros and cons, which I will not discuss, because... This is a matter of taste and does not apply to this review. I will only note that I liked it.
FullHD display 5.5” (480 dpi), made using OGS technology, without an air gap, has scratch protection and a simple oleophobic coating.
GPS works with 3 satellite systems: GPS, Glonass and Beidou, due to which it picks up quite quickly and determines the location quite accurately.
Cameras: CMOS 13MP at the back (f2.2) and 5MP at the front (f2.0) - naturally, they won’t provide professional quality, but they will completely replace the average 21MP point-and-shoot camera.
Also, the camera is capable of shooting 720p slow-motion video at 30fps; if you speed it up to normal, it will be 60fps. As it turned out later, maybe 120, but more on that below.
Sound... What's the sound? - External speakers are loud, the sound is clear, you can hear it clearly, without interruptions.
The fact that this is not a player is clear from the fact that it is a smartphone. (Your Captain Obvious)

Advantages and disadvantages

And finally, we move on to the “debriefing”

Pros of Xiaomi Redmi Note 2:

1.2) low price with very good characteristics;
3) strong and lightweight body, thoughtful design;
4) good cameras;
5) excellent GPS reception;
6) 2 SIM cards;
7) support.

Advantages of the Chinese version of Xiaomi Redmi Note 2:

1) even lower price;
2) it heats up less.

Disadvantages of Xiaomi Redmi Note 2:

1) the lid creaks in 3 places when strongly compressed;
2) 1 radio module (LTE works only in 1 slot);
3) you can’t just install root;
4) lack of Google Apps;
5) MIUI detects subscribers only at “+7”, but not at “8”.

Disadvantages of the Chinese version of Xiaomi Redmi Note 2:

1) crooked firmware from the seller
2) slightly less power The first and most tricky thing I came across was a crooked firmware of an incomprehensible version from the seller, downright infected with advertising.
Here, as they say, if you want it cheaper, know how to do it yourself. Flashing to the official firmware.

I. Flashing TWRP

Taken from here:
Download .
1) Install the ADB and USB VCOM drivers in the “ADB - Drivers” and “USB VCOM - Drivers” folders.
2) Turn off the smartphone.
3) You need to simultaneously press and hold “sound -” and “on” until the device starts to boot.
4) Fastboot has loaded, connect the USB cable.
5) Run “Recovery-Flasher (RUN ME).bat”.

II.Install the firmware

1) Download the firmware (weekly - rooted, stable (monthly) - no).
- English site (top - stable, bottom - weekly).
- Chinese site (top - stable, bottom - weekly, updated more often than in English).
- Russian site with localized firmware.
2) Copy the file to your smartphone.
3) Turn off the phone.

5) Section Wipe, swipe from left to right along the Swipe to Factoy Reset strip.
6) Install section, select the firmware file, swipe from left to right along the Swipe to Install strip, then click Wipe Cache/Dalvik and then Reboot System.

III.Connect mobile internet

Current on TELE2, possibly some other providers. TELE2 provides Internet in VSP (Virtual Service Provder) format using Rostelecom facilities, which is probably why it doesn’t work without roaming.
1) Lower the curtain, swipe from right to left, find the gear at the bottom and click, the settings section opens.
2) Go to SIM cards and mobile networks, turn on Data enabled.
3) Go to Overseas Roaming, enable Overseas data roaming.
4) go to the desktop, open the Tools folder, open Downloads there, click on the 3 dots in the upper right corner, select Settings.
5) In the Download size limit item, set the value to Unlimited and click OK.

IV.Install Google Apps

1) Go to the site
2) Select ARM64, Android 5.0 (you can see the current version in the About Phone settings), and micro (or any other configuration, this is enough for me).
3) Download and upload to your phone.
4) Turn off the phone.
5) Boot into TWRP (press “sound +” and “on”).
6) Install section, select the GAPPS file, swipe from left to right along the Swipe to Install strip, then click Wipe Cache/Dalvik and then Reboot System.

V.Install ROOT

Taken from here:
Here you need to make a reservation that if you installed “Developer’s” (weekly) firmware, then you already have ROOT installed, let’s start from point 6.
But if the “stable” version is installed, that’s a different matter.
We proceed as follows:
1) download the flashable SuperSU binary from here:

2) Transfer it to your phone.
3) Turn off the phone.
4) Boot into TWRP (press “sound +” and “on”).
5) Install section, select the SuperSU.zip file, swipe from left to right along the Swipe to Install strip, then click Wipe Cache/Dalvik and then Reboot System.
6) Install from the SuperSU market.
7) Go to the Tools-Security-Permissions-Root access folder, enable SuperSU access (you will have to click on “Allow” several times)
8) Login to SuperSU, update the binary, if required, reboot.

VI.Making “RAW” - photographs

Taken from here:
We will need:
1. Phone with the ability to enter the engineering menu.
2. .
3. A computer with OS Windows and Adobe Photoshop with Camera RAW installed (should be the default).
Instructions:
1) Enter the engineering menu on your phone using the combination *#*#3646633#*#* and go to the Hardware Testing tab, select Camera.
2) Set Capture type to Processed Raw, leave the rest as it is (in fact, you can change it and play with the settings) and click Start Preview. We take pictures.
3) Launch Adobe Photoshop and drag the raw file into it. In the dialogue window we set the following parameters: resolution 4192 by 3104, 1 channel, 16 bits, IBM PC, and click OK.
4) We get Malevich’s black square. Select Filter - Other - Custom, in the dialog box change the average value to 64 and click OK.
5) We get a B/W image. Next Save As and select Photoshop RAW format.
6) Download the raw2dng.zip file and unpack it. All the necessary settings are already written here in the ini file. We copy our RAW saved and processed in Photoshop into this folder. Next, take our RAW and drag it to raw2dng.exe and wait until the same DNG file appears in the folder. That's it, this file is ready for further processing in Photoshop.

VII.Shooting 120FPS

Taken from here:
