Hi guys. Thanks in advance for the support with this. My phone is the unlocked Nexus i9020A on T-Mobile network. I cannot go to 4.1.1 unless I'm on IMM76M. I downloaded the "P21ZDQWb.zip" and did the bootload/recovery but got the Status 7 error. The same I did with "q1-YQR3W.zip" and "cSwOyuoF.zip" files, but failed again. I also tried with the "Force Close/Clear Data" manual OTA instructions but failed each time after many, many attempts-I guess because I'm on 4.0.4 IMM76D and not 4.0.4 IMM76M. I did all of the above with and without the sim. I need help with this update. Much thanks and appreciation for the support.
