Hello,

I open new topic just in case anyone is facing the same issue.

The thing is that fingerprint is not working cause somehow the bootloader got unlocked. What it does it is to light up but doesn't capture the print, so it is basically useless.

As far as I readed, it dissables itself when detects bootloader is unlocked, so

I'm trying to lock it back again but no luck.

[Platform Tools] adb devices show my device as authorized, also works the "adb reboot bootloader" command, but then stuck in:

<Waiting for any device>

Not sure why is happening, maybe driver related? I guess I have all the drivers installed, but of course, there might be some drivers I unknowledge I need.

This would be a very huge help since I guess I could also make Putty to work (does not connect to COM port)

Thank you very much.

Are you getting this in fastboot? What command did you run?

Hello, no idea how but the fingerprint is working again. Only issue is that says: Key attestation problem.

About the command, I run what I wrote, didn't go through so I could test more commands.
