Asus Z00UD

Unknown

My asus z00ud 3gb 32gb is showing only fastboot mode. When i power on it opens fastboot mode. On recovery mode combination, it opens fastboot mode. Simple power on, it open fastboot mode. No adb debugging on and bootloader was unlocked before this happens. Between flashing through fastboot mode of its official service firmware. Its stopped on "asdf.img write failed."
Trying to install twrp, on pc it shows ok bt on handset it behaving same, opening fastboot mode screen. Any solution.?

Unknown Hi,
There are only two possible reasons why the device is stuck in fastboot mode,
first because of a damaged volume button,
and secondly an unsuitable recovery image.

So, the easiest way, make sure the device volume button is not a problem.
Then just reflash the device with the appropriate firmware.
Try starting first by flashing using the engineering firmware,
if at ASUS this firmware is called CSC firmware,
and of course it is available at UFI download support.
