Recover dead fingerprint scanner Android 8.1

Recover dead fingerprint scanner after full flash format

Please, use this tool only if you've lost your fingerprint scanner by formatting the flash chip or flashing an incompatible ROM

This solution is only for

UMIDIGI Z2, Z2 SE, Z2 Pro, One, One Pro, One Max, A3 and A3 Pro

running Android 8.1 system

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 ROM of your UMIDIGI smartphone! Fortunately, there's a working solution but since it's not a warranty related (manufacturing) issue and each phone needs to generate a unique activation file by our engineers, we can offer it only as a paid service. You'll have four steps to be done.

• Generate request file (its path will be C:\microtrust_metalog\the number you entered in the app as IMEI\thh.req).
• Send US $15.00 to ben@umidigi.com via PayPal or click the 'Buy Now' button below.
  
  Please note,
  - activation requests without payment will not be replied
  - once the activation file has been sent to you (our service is fulfilled), your payment is not refundable anymore.
• Send your thh.req file as an attachment to ben@umidigi.com with the subject ''Fingerprint activation A8.1'' and wait for the reply.
• Activate your phone using the file you received (its path must be C:\microtrust_metalog\ActiveResponse.txt).
  

Compatible models:

• UMIDIGI Z2
• UMIDIGI Z2 SE
• UMIDIGI Z2 Pro
• UMIDIGI One
• UMIDIGI One Pro
• UMIDIGI One Max
• UMIDIGI A3 (only with Android 8.1 system)
• UMIDIGI A3 Pro (only with Android 8.1 system)

Instructions (copied from the 'Remote activation tool manual.pdf' file but edited)
Download and install Microsoft .NET Framework 4 if you haven't yet installed it on your machine.

• Extract the content of the Beanpod_Activation_Tool.rar file.
• Turn off the mobile phone and disconnect from computer.
• Execute the following program: Generate_request_file_tool\Release\BeanpodFactoryTool.exe
• Enter IMEI: The IMEI entered here is only used for storing the path name of the activation request file and will not write the IMEI to the mobile phone. You can enter any number here but it must be alphanumeric and the length greater than 0.
• Click [Start] button, then quickly connect your phone to a USB port. Please do not connect via a USB hub.
• Connect the computer and mobile phone via the USB port. The tool will boot the phone into meta mode automatically.
• 5. [SUCCESS] will be shown on the screen if the execution succeeds.
• Brows for your generated thh.req file in C:\microtrust_metalog\the number you entered in the app as IMEI\. If that folder is empty or not even the C:\microtrust_metalog\the number you entered in the app as IMEI\ folder is present, run the Request tool again but now as an administrator.
• If your request file is properly generated, send US $15.00 to ben@umidigi.com via PayPal or click the 'Buy Now' button below.
  
• Email your thh.req file as an attachment to ben@umidigi.com and wait for the reply - you'll receive a file called ActiveResponse.txt. Please note, the fingerprint scanner requests will be processed once a week (usually on Mondays), so you can expect to get your activation file in 1-7 days.
• After you received the activation file [ActiveResponse.txt], please copy it into the C:\microtrust_metalog\ folder.
• Make sure your phone is turned off and disconnected from your computer.
• Execute the program: active_device_tool\Release\BeanpodFactoryTool.exe
• Click [Start] button, connect your phone to a USB port, and waite for the tool execution to complete。
• After the tool execution succeeded, turn on the mobile phone and set up the fingerprint scanner.

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.

Finally. Thanks a lot @bencebacsi. will try it now.

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

worked for me. Thanks
