Yesterday by my stupidity: grabli: wiped IMEI, and restored it for more than half a day, do not ask, where is your backup? yes yes I lost my breath and lost it. The whole PC went through it and did not find it o.O
Well, to the point of yesterday’s problem, I wiped (replaced) the files that lie along the path ROOT / protect_f, ROOT / protect_s, not all was erased but much that changed there, as a result, the network module was not working, and the MEID error when typing * # 06 Worn completely IMEI.
What actions were taken, the full firmware of the device did not bring results, in general, if I now describe everything directly by points, it will come out well, a huge text, the main thing is, I think, how I managed to restore the device.
Repair IMEI fromZorekIt did not bring fruit, this method did not work at all, it was also not possible to restore and through the programToolHero.
And then I came across a programMauiMETANow I’ll tell you how I restored wiped IMEI with it.

1) Download the driverAndroid_Gadget_CDC.rar(1.96 KB)

2) Download the applicationMauiMETA
3) Download the file for our phoneBPLGUInfoCustomAppSrcP_MT6572.rar(5.27 MB)
I personally put it in the folder with the stock firmware.
4) Run the program
5) PushOption
6) ChooseConnect Smart Phone In A Meta Mode
7) Instead ofCom1 set USB COM
8) ClickReconnect
9) We connect the switched off body to the PC with the pressed power button for 8-10 seconds
10) If you did everything correctly, then a red-green mug will appear yellow and the menu will openGet version , we close it and go to the main one.
11) Instead ofGet versio in the upper left corner of the program choose IMEI Download
12) A new window has opened, select an itemChange NVRAM Database File and select the file that we downloaded at the very beginning at point 3
13) Now clickUpload from flashe And we consider the IMEI curve, change Imei to SIM_1 for yours and press Download to flashe , and in the same way, change IMEI to SIM_2.
14) As you did everything we close the window in which you worked, and in the main window clickDisconnect
15) We distort the battery and enjoy our IMEI


Well, let's continue the story further, this is the only way that IMEI really restored me, for checking it connected to this program and reading IMEi everything stood as it should, thanksqpedot95 which I dropped files with ROOT / protect_f, ROOT / protect_s, I transferred them through the file manager with replacement, rebooted and it all worked.

0) Unpack SP_Flash_Tool_Win_v5.1552.zip to the root of any disk on the PC. Create a folder on the desktop of the PC, say with the name "recover" (without Cyrillic and no spaces and without quotes), put the files "MT6572_Android_scatter" (unpacked in .txt format ) and "recovery.img".
1) Install the driver on the PC, "MT65xx + Preloader"if not yet worth it.
2) On the smartphone, turn on USB debugging and turn off Fast Download! We charge the device by at least 50%, better by 100%.
3) Turn off the smartphone. CableDO NOT connect to the smartphone.
4) Remove and insert the battery back.
5) Run the program "SP Flash Tool" from the previously unpacked archive.
6) In the program "SP Flash Tool" click on the button "Scatter-loading" and select the file "MT6572_Android_scatter" (it lies in the folder "recover" with recovery.img, see item 0).
7) Press the "Download" button,important - the program should be set only one tick "recovery", flash as well as firmware, only in "Download Only ".
8) Only now we connect the phone to the computer with a cable. The program should see it and start the firmware. If the phone is not found, disconnect it from the computer, remove and insert the battery and reconnect to the computer.
9) The end of the firmware will show a color running strip. After the end of the firmware disconnect the cable from the phone.
Important! After TWRP firmware, you need to go into it and configure it! Otherwise, it will reset to stock.
Now TWRP Recovery 3.0 is installed on your phone. It starts when the phone is turned off, simultaneously holding down the "power on" and "volume plus" buttons. For convenience, to run it from the desktop of the phone, you can installВ®Reboot RecoveryorTWRP ManagerThey will work with root rights. Route rights caninstall through recovery.
