Engineering menu Xiaomi Redmi 4x and Note 3. Configuring
The engineering menu is designed to disable, configure or increase the effectiveness of various functions of the smartphone. camera, SIM card, internal memory, operating system, etc.
Entering the engineering menu of Xiaomi Redmi 4x, 4a, Redmi Note 3 and other smartphones of the line can be done in several ways: using service codes and special programs.
But, before we tell you how to do this, I would like to warn you that ignorance of the engineering menu options or incorrect phone settings using it can lead to the failure of one of the Redmi 4x functions or its breakdown. If you want to fix something, then first try resetting the settings to factory defaults, after making a backup.
The easiest way to enter the engineering menu of Xiaomi is the following service code:
## 3646633 ##
After entering it, a window in English will appear. If using this combination it was not possible to enter the menu, then try pressing the “memory” button five times in the standard settings of the phone.
To understand the seriousness of this section, consider a small example on setting up a Megafon SIM card. The functional of the engineering menu allows you to change the frequency of operation and thereby strengthen the signal, weaken or completely disable this function. Signal amplification can lead to increased loads on the Redmi 4x processor, which will damage the phone. A weakened signal will worsen the work of receiving and making calls in poorly covered areas of the network.

Xiaomi engineering menu
It often happens that Xiaomi smartphones start to work incorrectly. These can be various problems: problems with GPS, SIM cards, cameras, etc. In some cases, flashing the device can help, but why resort to such radical methods if you can go to the engineering menu of Xiaomi smartphone and configure everything yourself. The engineering menu is a utility built-in utility of the Android operating system that helps to diagnose both the software and hardware of your smartphone in more detail. But you cannot open this utility in the settings item, because it is carefully hidden from ordinary users so that they do not break firewood in their smartphone.
How to find the engineering menu of a smartphone from Xiaomi? You will find the answer to this question in our detailed article!
How to enter the engineering menu
I would like to note that not all Xiaomi smartphones can go equally into the engineering menu. Sometimes, you have to pick up certain options to do this. There are 2 main ways to enter the engineering menu:
- Using gadget settings
- using special USSD combinations that must be entered in the Phone application;
- by downloading the app from the Google Play Market.
We will deal with the first method. Go to your phone’s settings and select “About phone” or “About device”. You will see all the detailed information about your gadget: the version of the operating system, communication module, kernel, number of processor cores, etc. We need the item “Kernel version”. Tap on this item many times (about seven times depending on the smartphone) and the main page of the engineering menu will open in front of you.
The next way is to enter special combinations. It is advisable to resort to this method only when the first does not work. It is important to remember that the incorrect entry of special phone numbers can lead to a reset of your operating system or even a “bricking” of the device. This is due to the fact that each combination is some kind of service team, which is programmed by the developer in different ways. This can also be explained by the usual USSD combinations on your SIM card.
What combinations may be suitable for entering the engineering menu in a Xiaomi phone?
The last method is to download special applications that will help you quickly open the “engineer” on the Xiaomi device. Honestly, this is the most senseless way, since you clog up the internal storage of the gadget with various utilities, which is not good. Of the most common programs, MTK Engineering and MobileUncle Tools are worth mentioning. The most important drawback of applications for system maintenance is that these utilities often require superuser rights (ROOT rights).
What is the engineering menu for?
As mentioned earlier, the engineering menu of the Xiaomi gadget is needed to fix errors in the hardware and software, as well as a detailed diagnosis of the device. After you have entered this program, a “scary” list of 5 options will open before you. In order to go into the diagnosis itself, we tap on the Single Item Test. Using a translator, you can find out that this is a test of any one particular position. After clicking on this button, we will go to the engineering menu options, consisting of a 25-position list. Of the most important, we note such tests:
- SIM cards
- touchscreen and sensor calibration;
- speakers and much more.
As you can see, an “engineer” can be not only a dangerous option for your device, but also quite useful, as it helps to find a problem and solve it: “And why are these service centers needed?”
If the engineering menu does not open
If, for some incredible reason, the “engineer” does not open on your Xiaomi Mi6, which runs under MIUI 8 or 9, then third-party programs will help you. Let’s talk about free apps called MTK Engineering and MobileUncle Tools. Note that without superuser rights, you will not be able to use all the functionality of the applications in any way. This is done to protect system files from the hands of an inexperienced user. If you managed to “sew” ROOT rights into your gadget, then you have already gained some experience and can use all the charms of the engineering menu.
A utility called MTK Engineering works on all devices from Xiaomi. Despite its name, the application also supports Qualcomm chipsets. It has only two buttons on its main page: MTK Engineering Mode and Android Testing. To enter the device test menu, you must select the first item.
Like the previous program, MobileUncle Tools can be downloaded on the Market or on the w3bsit3-dns.com website. The developers did a good enough job at creating this utility, since it can not only enter the “engineer”, but also perform a number of other operations, for example, change IMEI, enter Recovery mode, update the custom recovery environment, and many others. etc. To enter our test menu, click on the “Engineering mode” button.
It must be remembered that it is not always worth resorting to downloading various applications if you cannot enter the Engineering Mode of your smartphone. Most often, the user entered the wrong USSD request, as it may change depending on the phone (the list of all possible can be found above in the article). If one number does not fit, it is worth checking the effectiveness of other codes. A method that works 100% in new versions of MIUI shells is a method with the inclusion of an “engineer” in the device’s settings.
