I used the "[Tutorial] How to fix qhsusb_bulk or qualcomm hs-usb qdloader 9008 brick" method to unbrick a HTC One M8, however I am unable to flash a RUU without error using fastboot/RUU or XTC2Clip. I did restore a stock OS via TWRP recovery and everything appeared to be working except sound and microphone.
I am only able to move between OS, bootloader and recovery with the mmcblk0.img SD Card inserted. If the SD Card is removed and any reboot action is done the phone returns to EDL mode.
Attached is a screenshot of an attempt to flash a stock ROM file. The phone was in RUU mode (from XTC2Clip) before flash command issued.
I have tried this with bootloader locked and unlocked with same result. Security is currently S-ON, but was S-OFF before brick.
Can anyone help resolve this situation?
