[G 2014 Q&A, Help & Troubleshooting] bla-bla-blubb:
Hi, I bricked my XT1072 (Thea) while I want to put lieneage OS on it.

Tried to restore with a wrong rom, should be for xt1068.

What ever it do not work now.

It just shows "warning bootloader onlocked" until the battery is empty.

I made a hard reset, but after that I only have lost TWRP.

I tried different stock roms but nothing works.

Looks like that:
