If you don't know how to search on forums, there is something called "Google".
You ask, Google gives the answer. Easy stuff

Rooting via Nexus Root Toolkit v1.6.2 for 4.2.2
Hey all,

It seems like the OP may not have too much experience like me based on his post count. The responders on the other hand seem like guru's.

Well I did some troubleshooting after 4.2.2 to try to get the rooting to work (yes, i used google search). Just for the record I'm new to all this, but I've been doing a lot of goog'ling and figured the time I spent troubleshooting may be of help to other novices.

Apparently the rooting issue is well known if you're using the Nexus Root Toolkit v1.6.2 to try and do your rooting. There's a fix available which is described on the main webpage (between the red lines)

google wugfresh for homepage (I can't post links yet)

Just download the zip file and unzip in the folder described, overwriting what's already there there. Make sure your drivers are working . They were acting really finicky for me when using the toolkit but I finally troubleshooted it. If you're having issues you may want to try the newest PdaNet driver, although I didn't have to. Once your drivers are fine, select the Android "any" option and hit root with Custom Recovery checked. I dunno about everyone else but my Custom Recovery was gone/messed-up after upgrading to 4.2.2

If you don't use Nexus Root Toolkit, I recommend it for the less computer savvy ppl out there, like me. Hopefully they'll come out with an update.

Hope this helps.

One newB question I have is can I install my 4.2.1 custom ROMs after upgrading to 4.2.2? I'm not sure if there's some kind of firmware component of 4.2.2 that'll render my Nexus 7 incompatible with the 4.2.1 custom ROMs out there. If it's not okay is it possible to downgrade back down to 4.2.1 from a factory image and then install these custom ROM's?

Thanks ahead of time.

Here's a tip, it seems like your a noob with the nexus 7. In order to mod this thing you should familiarize yourself with command prompt.

Re: 4.2.2 root is impossible :(
jesus people hate noobs here, why doesnt some just show them how to get adb and fastboot going, instruct on how to properly instal the adt and jdk bundles inc path etc. there are no easy tutorials for noobs, if people are expect to learn then teach them, dont forget we were all noobs once.

This might help. Go to this link and download the 4.1.2 (JZO54K) image for nexus7 wifi only if that's the one you got and downgrade everything to that and then root and download and install Chainfires SuperSU and SuperSU-Pro from the market and after you install that open SuperSU and check mark Survival Mode and then do the OTA update and you will still have root. Yes you can downgrade. I had to downgrade back to 4.2.1 and do what i said above. You have to have SuperSU Pro installed to use survival mode. its worth the price it cost.

After downloading the correct images from the link above

Follow these instructions

Nexus 7 Back to Stock

Step 1. fastboot erase boot

Step 2. fastboot format cache

Step 3. fastboot erase recovery

Step 4. fastboot format system

Step 5. fastboot format userdata

Step 6. fastboot flash bootloader bootloader-grouper-x.xx.img

Step 7. fastboot reboot-bootloader

Step 8. fastboot -w update

Step 9. fastboot reboot-bootloader

After you downgrade your device doing all the steps above then go and root the nexus 7 and install SuperSU and SuperSU-Pro check mark survival mode in superSU and Install busybox also from the google playstore and then do the ota update.

Unlock Boot Loader

fastboot oem unlock
fastboot reboot-bootloader

Lock Boot Loader

fastboot oem lock
fastboot reboot-bootloader
