[ONE Q&A, Help & Troubleshooting] stevieag:
My story goes.

Had happy running TugaPower Rom

Decided to install MultiRom and Ubuntu.

Then after running for a week or so, decided to wipe and install TugaPower alone.

All has run well for a while. Decided to wipe and make a fresh install.

MultiRom I am unable to fully remove, even trying to replace with original TWRP.

When I try to flash the ROM, I get reported that this cant be installed as the model is . not bacon or A0001. error 7

I have edited the updater-script to not make a check on the model and it then installs.

When i reboot it goes straight back to the recovery!!!

I have tried reinstalling multirom and then flashing but again it keeps going to the recovery.

Ive tried to fastboot the original OS via https://xdaforums.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541, but fastboot reports `FAILED (remote:	Device not unlocked cannot flash or erase)`

(Full output at bottom)

The install all end with 1 and multirom could see the roms

ive tried extracting just the .img and flashing to get going

im at a loss, any help much appreciated
