Another M9 bricked while locking bootloader



Hi all,

Here's another bricked M9. It happened after:

- HTC M9 official Firmware
- S-OFF with XTC2Clip Hardware
- Bootloader unlocked via HTC Dev
- TWRP and root
- Reflashed Stock recovery

After trying to relock the boot loader with an adb(su)-shell and following command:
echo -ne '\x00\x00\x00\x00' | dd of=/dev/block/mmcblk0p2 bs=1 seek=33796

did the device not start anymore. Nothing helped - no charging LED is glowing.
In the Windows device manager the phone is recognized as a serial port --> Qualcomm HS-USB QDLoader 9008

I can't reach it via adb or fastboot. The screen on the phone stays black.
Do you've any recommendations, hints or else?
