[One (M8) Q&A, Help & Troubleshooting] Niorun:
Evening,

My M8 won't boot up it gets stuck in the HTC screen.

I wanted to update my phone to be using the latest ARHD version. It's been a while since i did that.

First of all i've update recovery, that went ok. After that i've decided to flash firmware (3.28.401.7.zip) twice, that went ok as well.

But then i had to reboot my phone, and it gets stuck. I have no clue what i've done wrong. I've done this process before and there were no issues back then.

My CID and MID are correct according to the firmware i've flashed.

I am still able to reboot my phone with power button + volume up, and get into the bootloader that way. I can't get into Recovery as well, when i try to start Recovery i get the red triangle with the ! in the middle.

Thanks in advance,

Hereby the fastboot log;
