kitkat 4.4 update nexus7 2012 error

[charlie]

while running 4.4 ota I got an error msg "no command" I tried hard reset, unplug battery, nothing seems to help.

Give us a little more about your situation. Are you rooted? Which model N7? Regular OTA or sideload?

Did you have an alternate launcher installed? I've seen reports where next launcher is not compatible with 4.4, and the nex7 hangs on boot. If this is the case, boot into safe mode and change to stock launcher.

Safe mode: hold volume down when you see the Google logo until boot finishes.

yes rooted, reg. ota, "nexus 7 -18001A", nova launcher installed. cannot boot passed "no command screen. I have removed back and unpluged and repluged Batt. still as far as can boot is to no command screen. cannot turn it off, it keeps comming back on. I also tried the reset button.
I appreciate everyones help.

It may be hanging right when the launcher loads. To get to safe mode:
1. Hold power button until it reboots.
2. When you see the Google logo, release the power button and hold the volume down button.

It should boot to safe mode where you can change the launcher.

If you make it to safe mode, navigate to settings/apps click on nova launcher and clear defaults.

Cannot boot into safe mode,  boots to a green android that sez "no command" that's as far as I can go. but Matt I appreciate your help.

Sorry, saw a thread that mentioned no command, thought it might benefit.

Managed to get to the android with red triangle and no command by holding power and volume up during boot. Exited by holding power button for about a minute.

Seems like a flash mode waiting for adb maybe. Does the computer load any drivers when you plug it in? May need to flash os.

OK, that's the recovery screen. Hold power, press volume up, release power. Should be a menu to reboot, factory reset, etc. Don't wipe partitions.

If you can't get out of recovery?

If your rooted have you modded anything? Frozen apps with TiBu? Installed Xposed Framework? Edited any system files?

You may need to factory reset for the update to work...

 Wasn't there a repair option in one of the toolkits?

Hey J,  and chance of a 'side loading KitKat' tutorial in the future?  My OTA came and went and I've tried a few times to sideload but no dice...

I finely get a menu on my nexus 7-2012 that give me these options which still don't boot the device. "start, power off, recovery mode, restart bootloader" the only one that works in "power off" thats all I can get on the screen except the red triangle.

Did you have twrp installed? S. Prime mentioned having to reflash twrp when he hung on the recovery.
