Ok a few months ago I did some "updates" on my Nexus S I9020A from some instructions I took over the internet. Basicaly I rooted it,unlocked it and installed ICS 4.0 but the problem is that I had no idea of what I was doing. I downloaded 1000 files and tried until it would work. My phone has been very slow ever since and the radio kept shutting off randomly... Today I decided to bring it back stock... I followed some instructions and got it back with Android 2.0 but the radio wasn't working. I decided to get rid of clockworkmod... Now if I start it normaly (just with the power button), the animation just loops. If I start it in recovery, I get the exclamation mark..... Can I save my phone?
