I tried installing CM11 using CM installer in my HTC One(M7). I wanted to try this and didnt like much, so tried restocking the Stock OS using RUU. Unfortunately the RUU update threw an error 155.
I realized I had used a wrong RUU file. Now the Phone was stuck on HTC logo.
I tried to reload CM11 with CM installer. It got stuck in CM boot screen.
So I tried to restock another ROM using adb sideload command (My CWM was accessible). But that was a Google edition ROM and my S-ON was on. So again it is stuck in the Google boot screen.
I have tried almost all the options that I searched in XDA/youtube.
I know I am missing out some key things.
Request you all to help me to get out of this.
