[One (M8) Q&A, Help & Troubleshooting] EinReh:
I hope this is ok to ask here. I tried flashing the RUU from the first post. Everything seemed fine after I changed the model ID in the zip to match the one of my phone. After I erased the cache and try to reboot the phone, however I only get into the recovery menu. I have no idea what went wrong. Do you guys have an idea what I can try to fix it? S-Off was done with Sunshine.

Here is what's seen in the cmd.

And an image of the recovery screen that I get after rebooting.

Any help would be greatly appreciated as I have no idea what went wrong. Thanks so much!
