so after you flash the su zip in recovery, when you reboot you'll have supersu in your app drawer. or su. i forget which.

now you have root. you can flash roms, etc. etc,

so if i follow your steps, i shouldn't have any problem?

i have Windows 7 64-bit home premium. looking to unlock and root my Nexus 7 hopefully fixing my video playback problem (can't play most videos...) along with being able to use apps requiring rooted rom.

Yeah the tricky part on windows is getting the drivers. But the links should work I believe.

And for recovery, go with twrp over cwm. Cwm is wonky.

tranbo, download TWRP recovery, place inside the superboot folder where fastboot and adb are at, and flash in fastboot mode. link:

also, download this and place on your sd card:
(it's for 4.1 but i think it will work on 4.2)

so, flash TWRP in fastboot, when it's good scroll down to recovery - access TWRP, install the su zip, and then reboot.

clockwork is wonky. i'm going to take it out of the instructions. gl let me know if you have any issues.

since you reply late, so i can't wait anymore. I decided to get back to 4.1.2. and i rooted it with nexus root toolkit 1.5.5. right now, on this version, it can only root up to 4.1.2, not 4.2. I want to update to 4.2. I know i will lose root. I already install OTA root keeper and have it protected the root. If I update 4.2 through the ota update now, is it guaranteed that ota root keeper will restore the root for me successfully? I don't want to lose root and root again.

I don't know I haven't been stock since the day I got my tablet. Maybe someone who has updated to 4.2 can chime in?

OTA Rootkeeper should work just fine. Worst case scenario it literally takes just 2 minutes to root it using the "old fashioned" method

You'll want to update the OP to link to TWRP 2.3.2.1 for Grouper Btw.. Earlier ones won't work right with 4.2

EDIT: also the new SuperSU v.98.. Grab it from my Nexus 4 unlock thread.

Follow the directions in the guide.. use this recovery:
And in that recovery flash this file for root:

**zero neck** · 11-26-2012, 09:59 PM

updated for 4.2

finally

**vee2k** · 11-29-2012, 09:02 PM

Hey guys,
I followed this method to unlock my bootloader and root my nexus 7. Worked Perfectly! Only problem I am having is returning my recovery to stock so i can use ota updates and retain my root. I am currently on 4.1.2 and cant figure out how to update to 4.2.1. From what i can tell and read in other threads i need to be on stock recovery to be able to update or update and re-root? I guess i'm a little lost...
where can i get a copy of the stock recovery for the last step of this tutorial?

**sr2012** · 11-30-2012, 03:54 AM

Hey guys (and gals) thanks so much... Best and easiest rooting on MAC for Nexus 7 Android 4.2 ... It updated by itself to 4.2.1 apparently without needing stock recovery? Is this right?

Edit: Nevermind, I was already on 4.2.1.

Had problems with SuperSU but redid some steps now OK. Some forums say use SuperSU in "Grant" mode rather than "Prompt" for 4.2.1 so that it grants automatically...

Edit: AWESOME. Using ToggleBar I can hide navigation for Shadowgun: Deadzone FULL SCREEN

Let me look when I'm on a computer, I don't have the file on hand.
