i have successfuly unbrand my locked,vodafone branded 8X and flash a Stock HTC rom !
the process has been tested on PM232****/c620e Device & also 8S using different filename....
this process bypass the CID check like Wp7 goldcard & can also fix some bad flash/reboot loop.
use at your own risk.
I take no responsibility for any conflict or damage to your device
-sd card or usb drive key
-the 3 .nbh extracted from those 2 exe using winrar:
official rom HTC_Europe_2.00.401.03
How to flash:
1- Format your sdcard or usb key in fat32
2-Copy the file .nbh you want to flash to the usb key
3-Rename it ACDUDIAG.nbh
4-Connect the usb key to the Y-cable powered
5-Shutdown the phone press camera button and connect the cable
you will see the text ACDUDIAG.nbh on top left during 1 second
then the flash will start.
For my european device with Bootloader 162966 i have flash in this order:
(try different order for flash files if you have problem or if stuck on bootloader screen with uefi message)
I have used this step but i think you can directly flash
UEFI_signed.nbh then -RUU_Signed.nbh without Acdu depending on your software version
