My god I deleted my OS using twrp... So lets get start shooting off, so I had rooted phone but I wanted to unroot so I could install the new update of the HTC ONE SV Boost. I couldn't figure it out and I was desperate so I was thinking of stuff to do so I deleted every file in my htc one sv boost and it didn't work. So I tried to factory format and it didn't work, so I looked under advance and I saw system so I restore it and now I have no OS -__- I still have twrp I need some RUU or something so I cant install my OS again! Please someone help me!!!
