[One (M7) Q&A, Help & Troubleshooting] sphinxcs898:
I tried again to flash Maximus HD Rom (4.4.2). The AROMA installer completed its work and i tried rebooting. Same result. Back to Bootloader.

I saved the recovery log though. I've attached it here. But what was worrying is that it showed my /data and /external_sd as 0. Is that normal?

Any pointers here would be good.

Apart from help on that, I have one question: Would it be possible for me to achieve firewater S-OFF in this state?

The first step in firewater is to adb reboot. Seeing that I have no ROM to reboot into, would it work if I was doing it from recovery instead?

I don't know what other options I have.
