those who came from 4.2.1 rooted to 4.2.2 , does it wipe data after update and then reroot with this method?:

All my data is gone as i need to flash to factory stock and unroot. Previously root on stock rom cannot update. So no choice to do this step. After factory stock. Then apply an update and use the link method. So far so good and without issue. Realise google play is a bit different and toggle stuff. But stickmount still working after root is the most important.

paranoid android features are really cool and nice,but mostly only useful on phones

they say got improvement. Will try it tomorrow during long journey flight

should have a way to not flash stock 4.2.1..hmm

If you use nexus 7 toolkit to flash stock image midway you have option not to wipe your visible data. Only hidden partition data is wipe only n these can readily restore back from titanium backup

Thx for the heads up.

I tried many times, able to download but while installing, half way shown error sign. Any idea?

what error sign? any error message?

what is the improvement over 4.2.1?

Guys I have a problem with my n7. Sometimes when it boot, it automatically reset it's time and date to factory setting. Any idea why?

Only got this once,I think its a bug on 4.2.1

For those who need an app to extract the system.img files, etc, use this tool:

I managed to get the power.grouper.so from the stock 4.2.1 system.img and am flashing 4.2.2 now..

Updated my N7 firmware to Jelly Bean 4.2.2 this evening.

No message. Only droid laying down with error

will get my nexus 7 tomorrow..hopefully..wanna ask..do i need to update to 4.2.2 before root my device?or i can update after my device is already rooted later?

thkz for helping..btw this is my first android device..currently using windows phone

Finally updated my n7...seems like a hassle for a minor upgrade...

is it with X symbol or with exclamation mark? if exclamation mark is recovery mode..

BTW i managed to upgrade from 4.2.1 stock rooted with custom kernel to stock 4.2.2 (maintaining root) by doing this:

1. Use Voodoo OTA Rootkeper to backup your root and temporarily unroot.
2. Revert back to stock kernel here: http://forum.xda-developers.com/showthread.php?p=34254473
3. Revert to original power.grouper.so, extract system.img from google's 4.2.1 full 200mb+ original firmware and extract using http://forum.xda-developers.com/showthread.php?t=1921399. It's in /system/vendor/lib/hw
4. Get the new 4.2.2 update: http://android.clients.google.com/packages...0D.6ece895e.zip
5. Flash with custom recovery (I used TWRP at the time)
6. Reboot. Use voodoo ota rootkeeper to restore backup SU to get back root.
7. Flash TWRP or CWM using fastboot mode or you can use the Nexus 7 toolkit via menu option 11 (just choose 4.2.1 when prompted with firmware version, don't worry, option 11 will work with 4.2.2 too)

Done

Note: If you're on Custom ROM the above won't work for obvious reasons
