Question [Indian Version] Unlocked bootloader, fingerprint stopped working.

Search This thread
Yesterday I unlocked bootloader and tried to install custom rom.
Before that I disabled verity and flashed magisk patched boot.img.
Then I tried to install GSI custom rom.
I even succeeded in the attempt; I was able to install Pixel-experience gsi rom
But then came the issue, I was not able to register fingerprint.
So, I flashed stock rom. Still fingerprint does not work.

I don't have access to MSM flash tool. I tried to flash with italorecife's tool.
I couldn't flash some partitions with it. (Could flash them due to critical partition)

I even relocked the bootloader, still it doesn't work.

I am a newbie, so if someone could guide me on how to use MSM tool, or how to properly flash the stock rom.
Any help is appreciated.

Your device fingerprint hardware need calibration. It can be fixed at service centre.

After removing the GSI rom, flash the PERSIST partition in fastboot inorder to fix your FP problem.
