I've received an OTA update to Android 4.2.2 (I'm currently on 4.2.1). However, whenever I try to install it, the process fails partway through. I get an android on its back and the message Error! Nothing else. The phone becomes completely unresponsive until I remove the battery. No buttons have any effect.

I don't know what's with those who don't provide any kind of diagnostic info in error messages. How can I install the update?

By the way, my phone, a Galaxy Nexus, is rooted. The system ROM should be stock except that I've integrated most updates into the ROM and converted aLogcat into a system app so it can capture logging data.

  • Which Android version is it currently running? Modifications to the /system partition (root, integrated updates) might prevent it from updating (if the update checks the CRC of the partition).

  • I'm currently on 4.2.1. Other OTA updates have worked OK. I think, though I can't say for sure, that the changes I've made occurred prior to updating to 4.2.1. Feb 27, 2013 at 8:28
  • That should be a minor update, agreed, and usually not flash the entire partition. Though it might still check the CRC, not sure about that. Not having a Samsung GNex, I rather leave the answer to somebody who can tell first-hand.

    I'm seeing the same error, the gnex is rooted, but stock, other OTA's worked fine. I've tried 3 times now, same result.

Just flash the system.img(one from 4.2.1) over your current system, also make sure you're running the corresponding recovery, radio, kernel, and bootloader that came with your takju/yakju factory image.
Do that and and try the OTA again, should work.
"Flashing system.img didn't wipe data/app"(Just backup if you are worried about losing data/app) NOTE:You will lose root

or else try flashing 4.2.2 manually from here

  • Use mobile Odin App. Its simple one.

  • Isn't Odin just for regular Samsung devices? Even though Samsung made the Galaxy Nexus, as a Nexus device it's quite different from a typical Samsung device. Also, isn't Odin Windows-only? All my computers are Linux; I don't have Windows or the ability to run Windows software. Feb 28, 2013 at 8:18
  • You misunderstood. Mobile Odin is a Mobile App
