Re: How I upgraded my AT&T Nexus S (I9020A) to Jelly Bean (Android 4.1.1)
I've taken this phone home to India after buying it in the US and am using it with an Indian SIM. I cannot seem to get the phone updated any more? Any particular reason why? I tried the above method, wouldn't work. is there a detailed website that shows how to update 2.3.4 to 4.1.2? Do we need to update to all intermediary OS's before getting to the latest version?
