view story

http://forum.xda-developers.com – I'm a Noob with a problem. I believe this is what happen i updated the one s via OTA 1.84.531 gave me hboot 1.140004 and radio 1.08ts.50.02.16 then i decided to Root. when I rooted i flashed to a rom that apparently broke my wifi. I did not have a nandroid backup (epic FAIL) so i found the 1.53 stock nadroid on a forum inorder to unroot and flash RUU 1.53 which should re flash the One s to stock and fix wifi. After re locking boot loader and trying RUU 1.53.531 and 1.84 get error "155" from RUU, so i tried OTA, OTA downloaded but fails on install. what i believe i need is a non roote (HowTos)
