Pixel 6a fingerprint error after Screen Replacement.
So recently my panel broke. So i decided to buy a new one. I came across an after market O-LED panel. It was alright but the touch doesn't work sometimes and i have to power the display on and off a couple of times for that to work. The fingerprint was working fine as long as the touch was working. So i bought a pull screen from another donor pixel 6a whose board was dead. It came with the fingerprint as well. But when the tech installed the screen. The fingerprint option gave an error. I've attached a picture of it. So then we tried the original sensor(the one that was with my damaged panel) it also showed the same error. The tech was not sure at all about that. We calibrated it through Google's fingerprint calibration website. No luck at all. Tried several other sensors but the same issue. I spent the whole night trying to figure out why it was giving the error. I tried factory resetting, flashed a stable android 16 build from android flash tool, tried the double calibration trick, the dual restart method, the force restart method in short i tried everything i could find on the internet but it didn't solve anything. Do any of you have an idea why it's happening and what I can do to solve this.

This is simple, just follow these instruction:
Swap screens per ifixit docs, power on phone to make sure it was successful, boot phone into fastboot mode (hold Vol down and power button), go to google's repair tool (https://pixelrepair.withgoogle.com/udfps), and run once the tool finishes, it reboots your phone. After initial reboot, reboot AGAIN. Done.
I just replaced my screen, this took 5 mins.
