Backup any data you want to keep, as the downgrade process will wipe your device.
Download the A9 downgrade UL file from our support website. (Link below.)
Put the file in the root directory of your device.
The system should detect it as new firmware and prompt you to run it.
Wait for the process to finish, your device will reboot.
