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

Does anyones System info show version 4.1.1? I updated and it was stopped by CWR, so I dont know if I lost root or even got the update. My version still shows plain 4.1.

How can I verify if I received 4.1.1 definitely?
How do I check if I'm rooted?

The first update will "fail" since you have CWM installed. So go to choose zip from sdcard, make sure signature verification is off, apply the file. Once you boot up your system apps will update.

Not sure why the screens didn't post, but here they are again.

If you installed voodoo you'll keep root, if not use Paul's root method with insecure boot.img to regain root.

Yea, it's been blocked a few times for other "leaks" or updates haha

Also curious to see how many people actually applied this update or waiting for the OTA

Hi, I updated my Yakju to the 4.1 Takju a week or two back - trying to install the 4.1.1 update even with signature verification fails (assert failed: apply_patch_check(<bunch of hex>)

What do I need to do? Do I need to revert back to 4.0.4 + wipe or is there a simpler way?

Ignore - I seem to be in the nexus 7 forum (idiot)

I also have the takju and yakju ota files for the regular nexus if you need them :)

    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://forum.xda-developers.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..

    ./adb reboot bootloader
    ./fastboot flash recovery recovery-clockwork-6.0.1.0-grouper.img
    ./fastboot reboot

    Go upgrade.

    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.
