When I try to update my Nexus 7 from 4.1 (Jelly Bean) to 4.2 (also Jelly Bean) it works fine up to a point where the little android (with the rotating shape) lays down and has a red warning triangle with an exclamation point. When I press the power and VolUp buttons simultaneously to see what went wrong, the log shows this:
Verifying current system Assert failed: apply_patch_check("EMMC:/dev/block/platform/sdhci- tegra.3/by-name/LNX:5013504:c48f8e86e73fb2c2ba1794f5ec98e27c9e206ed5: 5060608:319331fae14fec8a88063751475fce26bae328e0")
I searched for the error message online and couldn't find anyone with the same problem. I even removed the random letters and numbers after "by-name" (I assume these are device-specific), and still found nothing. I also tried factory resetting and still the same problem.
I'd like to know what went wrong, and how to fix it.
