Android 8.1: Recover dead fingerprint scanner after full flash format

bencebacsi

As a requirement of Google GMS verification, UMIDIGI smartphones shipped with Android 8.1 system store unique identifiers of the fingerprint scanner on a special (tee) partition. It's similar to the nvram partition, that stores IMEI, mac address and other unique identifiers, however unlike for the nvram (SN Writer or Maui META), a free tool to recover the fingerprint scanner data on the tee partition is not available. By formatting the whole flash chip (not only the partitions and data shipped with factory ROMs), that unique data will be deleted without the possibility of recovering it. Please never format the full flash of your UMIDIGI smartphone! Fortunately, there's a working solution. You'll have three steps to be done.

1. Generate request file (its path will be C:\microtrust_metalog\the number you entered in the app\thh.req).
2. Send your thh.req file as an attachment to ben@umidigi.com with the subject ''Fingerprint activation'' and wait for the reply.
3. Activate your phone using the file you received (its path must be C:\microtrust_metalog\ActiveResponse.txt).

>>> Resources: Beanpod_Activation_Tool.rar <<<

Instructions (copied from the 'Remote activation tool manual.pdf' file)
Download and install Microsoft .NET Framework 4 if you haven't yet installed it on your machine.
1. Turn off the mobile phone and disconnect from computer.
2. Execute the following program: Generate_request_file_tool\Release\BeanpodFactoryTool.exe
3. Enter IMEI: The IMEI entered here is only used to store the path name of the activation request file and will not write the IMEI to the mobile phone. User can also enter other information and not using the device information. Must be alphanumeric and the length greater than 0.
4. Click [Start] button
5. Connect the computer and mobile phone via the USB port. The tool will lead the phone into meta mode automatically.
5. [SUCCESS] will be shown on the screen If execution succeeds.
6. After the request file generated, send the file which is under C:\microtrust_metalog\ to the dongle responsible person(the file generated by mobile phone will be saved under the directory C:\microtrust_metalog\IMEI\thh.req）
7. The dongle responsible person will make the response file(ActiveResponse.txt) according to the request file.
8. After received the response file [ActiveResponse.txt], please put this file under “C:\microtrust_metalog\”.
9.Make sure the mobile phone has been turned off and disconnect from the computer.
10. Execute the program: active_device_tool\Release\BeanpodFactoryTool.exe
11. Click [Start] button and connect the mobile phone by USB port, and waite for the tool execution to complete。
12. After the toll execution succeeded, turn on the mobile phone and test the fingerprint module.

Yes, please wait for the reply. We can't keep it as a rapid service forever. The link to a new flash tool tutorial is available on every new ROM page for quite a while, and that tutorial clearly ask you to never flash your phone in format all + download mode.

Hey @bencebacsi how long might it take for us to receive the response file after we send the request ...

It was weekend now but I probably can send the activation file today. I does not depend on me, so I can say only probably, not certainly.

First your phone has to switch into preloader mode to be able to swith into meta mode. Then you can see the boot screen until the process finishes. Sorry but how could you format the flash chip of your phone if you can't even connect it in preloader mode? Check your Windows device manager when conneceting your phone to USB. If you can use SP Flash Tool and SN Writer Tool, using this activation tool should not cause any specific issue
