Many users prefer to perform various actions with their smartphones, which can lead to serious consequences. Quite a common problem is when the IMEI code is missing or flies off. So today, we will discuss restoring IMEI on Xiaomi, what can cause it to go off, and how to prevent it.
What is IMEI, and how can it go off
IMEI is an essential detail on any phone responsible for mobile communication. The code itself consists of 16 unique numbers. The number can be easily found on the box if the purchased device is an original one. The IMEI is given to each SIM card slot, i.e., phones with two SIM cards will have two IMEIs.
Why IMEI is sometimes missing or absent at all:
- Counterfeit. The smartphone does not correspond to the set standards; it was bought from an unscrupulous seller and is a low-quality Chinese fake. Learn how to check your Xiaomi phone for originality.
- The fault of the user. For example, the wrong firmware was installed, and a virus got in. Or the device’s owner got root rights and accidentally deleted system-important files.
- Another factor is independent of the seller and the end user.
The problems with the IMEI are expressed as follows:
- Lack of cellular communication. You cannot call from absolutely all operators.
- SMS messages are not sent.
- Mobile Internet refuses to work despite active data transfer and sufficient megabytes.
Repair IMEI on an unlocked bootloader (root rights)
There is a fairly simple way to get the IMEI back working quickly. But you will need to have ROOT rights and an unlocked bootloader. All actions will take place in a special utility called Android Terminal Emulator.
This is a great application for advanced users, allowing you to perform serious operations with your mobile device at the system level without using a computer.
So, to begin with, we download the program from Google Play. When prompted, we open the utility and grant access to root rights.
Now we take the box from the phone and look on the back to see their IMEIs for the two Sim cards.
Next, enter the query “Su”. Now enter the following commands:
echo ‘AT+EGMR=1,7,’IMEI_1 value” >/dev/radio/pttycmd1
echo ‘AT+EGMR=1,10, “IMEI_2 value”‘ >/dev/radio/pttycmd1
After performing this operation phone should reboot, and mobile communication will be available again.
Repair IMEI on locked bootloader (TestPoint)
Alas, restoring IMEI on Xiaomi with a locked bootloader is very difficult. Practically the only way out is flashing via TestPoint (EDL). The difficulty is that the global version can be immediately uninstalled. Therefore you will have to choose MIUI China Developer.
Be careful and if you face any difficulties write to the comments or visit an Authorized Service Center.
FAQ
Is the ID number and serial number the same thing?
No, the serial number is much harder to break and recover. It usually changes itself after updates, and that’s quite normal. Please don’t pay attention to it. It doesn’t play as important a role in the device as the IMEI.
IMEI will be lost during flashing or update?
If you do the right thing, IMEI will not be lost again. The main thing is not to block the bootloader in case of anything.
Will a full system wipe restore IMEI?
Some users wrote us about restoring their IMEI, but there is almost no chance. Better use one of the available options.
Can I completely change the IMEI?
As of 2018, this procedure is strictly prohibited by the manufacturer.
In this article, we looked at 2 ways to restore IMEI on Xiaomi if lost. In principle, these instructions can be repeated on any Android phone. There is no critical difficulty here, but it is necessary to approach the process carefully and carefully.
