A few years ago I rooted my HTC Sensation (Xe) (and have since moved on to Sony's, non rooted) and have a friends HTC One that she was given.
When she was given the phone, it had Cm10 (possibly 11) and was not locked to her network. No problem, i thought. I'll just stick a new Sense Rom on it and that'll be fine (as i used to do with my XE).
I did that, went through the trusty Aroma installer where it warned me that Doing so may lose root, but i still proceeded .
Since installing that , the phone now just bootloops, there seems to be no recovery on there to boot from. I've tried dicking about with the ADB settings and Fastboot but can't get the phone to connect to my computer.
I think that once I've got recovery on there i should be able to change the CID and then put an unlocked, stock Rom on there.
If anyone can help, that would be amazing. Sorry if i missed this information posted elsewhere!
