How to repair IMEI phone on "Android"

Sometimes there are situations when the beloved smartphone began to glitch and you, in order to save money, decided not to carry it to the service center (SC), and to do firmware of the device yourself. But it also happens that the firmware was installed normally, and everything works, but you can not call from the device. So you have lost IMEI. What is it, and how to restore IMEI to "Android" after the firmware, we will discuss a little lower. But everything you are going to do with your gadget, you do at your own risk.

What is IMEI phone

IMEI is the abbreviation of the English term International Mobile Equipment Identity, which in literal translation means the International Mobile Equipment Identifier. Simply put, this is a special code used to detect and identify a phone in a mobile network. Of course, not just the entire phone, but only its radio module. Without this 15-digit number, the phone can not receive and send calls. It's very easy to learn IMEI. It is enough to dial * # 06 # on the phone's keyboard, and it will be displayed on the screen. If instead of normal numbers you see some kind of "abracadabra", it means that your IMEI has flown due to the "curve" firmware or your inept actions. No problem. In most cases, IMEI can be restored.

Initially, the "superuser" mode is disabled in all smartphones, and if you decide to receive it, you should remember that the current warranty (if any) will become invalid after that.

Devices based on the MTK processor

Each manufacturer has in its arsenal devices based on MTK processors. If you have such a device, then consider that you are very lucky.

Recovery of IMEI on Lenovo devices

The devices of the glorious Chinese company Lenovo also have some problems with the recovery of IMEI, although not as serious as Samsung's. Here the Chinese are ahead of the Koreans. To restore you need only one program called MobileUncleTools. It's free, you can find it and download it without any difficulty. In addition, you can use the program Maui Meta 3G. But MobileUncleTools is much more popular, so we'll sort it out. So, how to restore IMEI on Android-smartphone from Lenovo?

1. Install the program MobileUncleTools and all the necessary drivers for your device.
2. Run the program, press the Engineer Mode button, then MTK Engineer Mode and finally find ourselves in the engineering menu of the smartphone. It is very important that in the process of all manipulation the phone is not disconnected from the computer before the deadline!
3. We write off the IMEI phone. To do this, open the back cover and take out the battery.
4. We connect the phone to the computer, look for the CDS Information tab in the program, click on Radio Information and Phone 1.
5. At the command line of the program, enter the command AT + EGMR = 1,7, "imei", where imei - just written off by you IMEI phone.
6. Click the Send AT Command button and wait.
7. After the successful completion, we reboot the device and check the IMEI.

As you can see, we did not have to puzzle over how to restore IMEI. Lenovo did not block access to the file system of their smartphones. For what they honor and praise. In general, the MobileUncleTools program is suitable for all devices based on MTK processors. So if you do not get the engineering codes from the first method, and you do not know how to restore IMEI to "Android" after the firmware, then you can try MobileUncleTools. This program should help. Moreover, it is quite easy to use it. The main thing is to follow instructions exactly, otherwise you can get a "brick", which you can not independently revive.

If everything is done correctly, the device will still please you for a certain number of years. But if not, then the service center can not be avoided. Although few SC agree to take up repair of phones in the system of which someone has already "rummaged", and if they do, they do not especially break their heads and instead of restoring they simply change the whole motherboard. And this is completely different money.

Recovery on Explay smartphones

Now let's look at how to restore the IMEI phone from Explay. This Russian company has long been known in the mobile device market. Their devices combine high quality and attractive price. Here almost everything is like that of the Chinese. In general, there is a certain similarity between smartphones Lenovo and Explay. How to repair an IMEI device? Yes, as well as a smartphone from Lenovo. Both companies use MTK processors. Therefore, you can use both Lenovo's method with the MobileUncleTools program and the second way: using the original Maui Meta 3G program.

1. Download and install the program Maui Meta 3G. Install the necessary drivers for the device (if not installed).
2. Run the program. In the Action tab, click the Open NVRAM Database File button and select the file named BPLGUInfoCustomAppSrcP_MT6582 from the pre-downloaded firmware for your gadget.
3. Then we press the Disconnect button, turn off the phone and connect it to the computer.
4. Click the Download IMEI button and in the window that appears, enter the previously written off IMEI without the last digit. It will appear later. Click Download To Flash and wait.
5. At the end of the process, disconnect the device and start it. Check the IMEI, and if it's okay, close the program window.

As you can see, in the process of IMEI recovery on Explay smartphones there is nothing too complicated. The process is similar in many respects to smartphones from Lenovo. Samsung alone was greedy to open its phone system to users. On the one hand, this is correct - there is less danger that the phone will be "killed" by those who inadvertently climbed into its firmware. Perhaps, this is exactly what Samsung did for calculation. To restore IMEI on it by own strength is almost impossible. So you have to pay a tidy amount to specialists from the SO.

IMEI Recovery in "Thoroughbred Chinese"

First, we need to understand the term "purebred Chinese". Such a phrase is usually called cheap copies of expensive smartphones, collected by hard-working Chinese from cheap components. This smartphone is distinguished by a "crooked" translation of the system into Russian, by the presence of unnecessary functions. And in very frequent cases in smartphones there is a TV set. Screens, as a rule, are not capacitive. They have to "poke" something subtle, so that they work normally. But still and sometimes they install "Android", although quite "krivenky". And this means that the question of how to restore IMEI on "Android" smartphones, is relevant for these crafts too.

It should be separately noted, - the restoration of IMEI Chinese phone - it's not in Huawei or Lenovo, everything is much more complicated here. If in the construction of system folders of "normal" smartphones there is at least some logic, then in this case it is completely absent. And the right file is much easier to download from the Internet. But even if the desired firmware for a smartphone is found, this does not end there.

The fact is that the "gray" Chinese smartphones are connected to the computer using a USB cable. But for flashing the phone you need a cable with a very different pinout of the contacts! So you have to solder yourself. The correct wiring schemes for a particular smartphone model can be found on specialized resources. After the firmware is found and the cable is decoupled, the task is greatly simplified.

Now you can use the IMEI recovery method, as exemplified by Explay and Lenovo smartphones. Strangely enough, the "purebred Chinese" also have MTK processors installed. So, download MobileUncleTools or Maui Meta 3G and work on instructions for Lenovo and Explay. If the first method did not help, we use the second one. The percentage of success in the recovery of IMEI Chinese, of course, is small, but in most cases these two methods can help to get the phone out of the "brick" state.

In general, in order to avoid frequent problems it would be better not to purchase such smartphones at all. But if it does happen, do not try to sew it yourself. Since problems with them will later be nemereno. However, if this has already happened, the IMEI repair method described in this article will help get your phone back to a working state.

Guarantee

It is also important to remember that if the phone has problems with IMEI, and the warranty has not expired, then it can and should be handed over for service to a warranty service center. If this is not done, then after some software or hardware actions with the phone, the warranty may become invalid.

Conclusion

So, what did we learn about how to restore IMEI to "Android" smartphones? IMEI recovery is possible. The complexity of the process depends on the manufacturer of the phone. Samsung has serious problems with the possibility of self-repair IMEI. And smartphones from Lenovo and Explay are rather pliable in this regard. If you like to work hard, you can revive the gray Chinese smartphone. The main thing is to follow instructions exactly, and everything should turn out.

Of course, this article is only a general guide. In some cases, you will have to turn to specialists from the service center, especially if during any manipulations the smartphone will no longer turn on, and the emergency mode sign on the screen lights up.

And finally, advice. Whatever you do with your smartphone - always create a backup of the system. If you have a copy, then it will be much easier to restore IMEI after the firmware.
