problems updating to 4.2.2

[bldrgn2043]

My nexus is unlocked and rooted. I'm using nexus root toolkit v1.6.2 and I have twrp on my nexus. I have tried updating through system settings by going to apps/google play services and cleaning the cache data, then going to "about tablet" and checking system update. It downloads the update fine, but after restarting it loads into boot-recovery, but it gets stuck at the twrp options page and doesn't load the update like it normally would if it was stock/unrooted.

I have also tried flashing the 4.2.2 .img with the nexus root toolkit and it always get seems to get stuck at the google boot image. I'm not sure how long it should take I gave it a good 2 mins on the google boot screen before I went into twrp and restored from a backup I did right before trying to update.

Not really sure what to do next any help would be great.

1) you can't install an OTA if you have a custom recovery, as you do.
2) You can't (yet) use the root toolkit to install 4.2.2. If you are able to get back into recovery than that means you never actaully flashed the 4.2.2 img because it would have wiped everything, including the custom recovery (TWRP) and any saved backup you had.

I'd suggest just hitting up 2def's guide here http://forums.androidcentral.com/ne...1477-guide-nexus-7-factory-image-restore.html
and doing it manually, it's not that hard and if you have the toolkit installed already I'm sure you drivers are already setup.

Another options would be to restore your n7 back to 4.2.1 with the toolkit and take the OTA as if you were stock then reroot it manually after you are on 4.2.2. You could backup your stuff via TiBu and then copying everything you wanted over to your computer since a restore will wipe everything.

You probably could flash the stock recovery back also and just take the OTA, but you'll lose root when you do that and I'm not sure where a copy of the stock recovery is. You wouldn't need to back up that way but you would need to reroot.

good luck!

Thanks, I'll back all my stuff up with TiBu and then try 2def's guide and put it back to 4.2.1 stock, then take the OTA. Hope rooting and unlocking has stayed the same. Thanks for your help digitalslacker.
