FAQ

Can this tool pull my device out of bootloop?

Yes, if you have made a backup beforehand. Flashing backups from other devices (even same model) is not recommended - your serial number and other factory settings will be overwritten with no chance of recovery.

Can I restore using backup from another model onto my device?

No, it will brick your device. There are no checks, so be careful.

"Unrecognized device driver" / "Open failed" error

You need to remove all related drivers first.

1. Open PowerShell as admin
2. pnputil /enum-drivers
3. Look for VID_0E8D&PID_2000, write down related inf names (oem<number>.inf)
4. Remove driver packets: pnputil -f -d oem<number>.inf
5. (Just in case) Reboot
6. Run the tool again
