Personally if you can get into recovery (team win recovery project) or stock - try just doing a factory reset (wipe data and cache).
Also- you are in the wrong forum. This is the USA Verizon wireless HTC One forum. You should be in the international One forum.
Thirdly - it sounds like you really don't understand any of this so you need to do some reading on how the entire process works because if you end up having to wipe your system its going to get complicated
