Hi.
Im from brazil. I bought a galaxy nexus a few months ago(warranty already expired) in a local shop. It was on version 4.0.4 on a non yakju build(yakjuxw).
One day the OS asked me to update my android and so i did. But, when the phone was back on, it was updated to 4.1.1, but, my IMEI and Baseband became unkown under the status menu.
I know that non-yakju cellphones get their OTA update from samumg and not from google. But, what could be the problem? I didnt make any backup as i thought that an OTA update would have no issues. I already tried to flash the google yakju 4.1.1 stock image from google but the problem still persists.

I tried several fixes, including one that says that removing the battery for some time helps to recover, but no success yet.
Im really afraid that i lost my phone after paying a fortune for it.
Can anyone help me?

Thanks a lot!

Another information:
The battery is ending too fast, much faster than before, and the airplane mode gets toggled once in a while.

Thx

Hmm, could you please explain me the difference?
And where can i find material to do that?

For me, the flashing takes place to wipe out the entire system information and change it to another one, i didnt know there was a specific type of flashing that surrogate a folder or some part of the system.

Thanks a lot!

It doesnt mean anything special, really. In the download from Google there is a file called radio.img (or something to that effect.). Not sure of how you reflashed your phone....but the image from google includes three .img files, and each should be pushed to your phone.

Did the phone notify you of an update or did I you download it from somewhere and install it?
