Hi *,

I hava a xiaomi mi a3 with broken screen, i already rooted and enable debugging previous of the broken.

Now i would use scrcpy but adb listing my device as unhautorized.

I see in other post that i need to copy the key on /android/data/..., but i unable because adb shell does not work, so i read that entering in fastboot mode i able to copy the files without key.

So i powered off the phone and restart with volume up+power and i see this on my syslog

I tryed to run adb but it seems always recognized it as unhautorized, fastboot devices command instead does not report any output:

alessandro@debian-z230:~$ fastboot devices

alessandro@debian-z230:~$ fastboot reboot

< waiting for any device >

alessandro@debian-z230:~$ adb devices

List of devices attached

if the phone starts in normal mode instead on the syslog i see this

so seems that product, vendor and device id is different.

Could someone confirm that the first id, of product vendor and device is fastboot device?

There is a method to solve this impasse?

Thanks a lot to all

so the vendor product and device is different
