I forgot to post/upload the file to go to JOZ54K from JRO03S, it's in the OP :)

Also, if the links are down it's because Dropbox took them down due to too much traffic. If you want to donate for a Mediafire account, please consider it to be able to keep links alive longer.

I finally got around to upgrading to 4.1.2 on my rooted Nexus 7 with clockwork mod installed when I received the OTA this morning. Reverted back to 213 DPI from 160, and used root keeper, to preserve root but clockworkmod aborted with error 7 when flashing the zip. This appeared to be due to a checksum difference between the installed plusone.apk and that expected by the update install script. The web is full suggestions this is due to a bad 4.1.2 zip file, but as the link below suggests if any of the system apk files have been modified an error 7 could/will occur.

Just in case any one experiences the same problem try downloading the modified zip from the link, which work for me and saved me reverting to stock, and left all my apps installed, after the upgrade.

The modified 4.1.2 is for JRO03D, not JRO03S.

My last mistake was with the kernel, it wasn't stock kernel.
I found it somewhere on XDA and i could update to 4.1.2 successfully :)

Thanx xda !

    Removed all my Dropbox links because they disabled my account due to too much traffic, if you guys want them back please consider donating a buck or two for a Mediafire Pro account...
    ​
    Here is the download, use Voodo OTA to keep root, apply via stock recovery or CWM...if using CWM make sure you turn signature verification off

    mirror JRO03C-from-JRN84D

    mirror JRO03D-from-JRO03C

    update from 10/09/2012, apply the same as you did the last update

    mirror JZO54K-from-JRO03D

    mirrors thanks to dapezboy

    also added a donate link to me since a lot of people have asked about it and also hopefully to fund a Mediafire account, it keeps getting too much traffic and shutting down my Dropbox links :(...find it under my username on the left :)

    This is what I did to get a completely clean install of 4.1.2 with root. I had been meaning to completely wipe the device and start fresh so this was the perfect opportunity.

    1. Copied all data I wanted from sdcard to my PC.
    2. fastboot oem lock/fastboot oem unlock.
    3. Flashed stock image as described here: http://xdaforums.com/showthread.php?t=1781250
    4. Rebooted, synched things up, then flashed the official 4.1.2 update using adb sideload in stock recovery as described here: http://www.androidpolice.com/2012/1...d-4-1-2-jzo54k-with-stock-or-custom-recovery/
    5. Flashed twrp recovery using "fastboot flash recovery recoveryfilename.img". File here: http://www.teamw.in/project/twrp2/103
    6. Then booted directly in twrp, changed the stock recovery overwrite file mentioned in the twrp instructions, and flashed SuperSU 0.96 found here: http://download.chainfire.eu/212/SuperSU/CWM-SuperSU-v0.96.zip
    7. Selectively copied back my backed up data, with the titamium pro licence text file and tb folder being the most important.
    8. Restored apps with titanium backup.

    I'm on stock and rooted JRO03D and I'd apply new stock update 4.1.2 posted in OP, but since some users can't use cwm anymore after update I think I'll wait until someone finds a solution..
