[Q] Help update to stock 4.2.2 from custom rom 4.2.1

---

Hi

First of all, this is don't habitual for me since I used to read related post (and more if an update has just arrived) but I just could not find an specific instructions (sorry if I am being too demanding) to go from custom 4.2.1(PA) to stock and finish with rooted 4.2.2, there are a lot of several procedures or recommendations to perform the update :S
well this is what I have planed
- return to stock 4.2.1 (using nexus toolkit)
- download and flash manually the update to 4.2.2 (first try to use the ota update option)
- get root... how??? lol
- restore my apps/data

Since I will return to stock I think I will lose root, that is ok but only if i can root the nexus again, Will I be able to get root on 4.2.2? or I have to root in 4.2.1 and keep it (in some way) at the time I update to 4.2.2

Rooting every nexus is the same. Flash/boot a custom recovery and flash supersu.zip. it doesn't matter what OS version its on.

ok, I think I have missing that simple thing...
I don't have to worry about get the bootloader locked again therefore I just have to flash a recovery and SU when I have my N7 on 4.2.2, but...flash from... bootloader I guess, well, I will check that.

Thanks!

Learn the manual way of doing it and don't rely on toolkits. There are many tutorials walking you through the entire process

To elaborate on Pirateghost's points...

After flashing the 4.2.2 update... you will lose your recovery (CWM or TWRP)... but getting your recovery back is also part of how you (re)gain root.

As I have posted elsewhere...

Rooting is really simple.

(You will need an unlocked bootloader for this).

Get a custom recovery .img for your device...

Either CWM - http://www.clockworkmod.com/rommanager

...or TWRP - http://www.teamw.in/project/twrp2/103,

...it matters little which...

-----------

fastboot flash it.

-----------

Get Chainfires SU .zip package here http://download.chainfire.eu/310/Sup...erSU-v1.04.zip

Flash it using the custom recovery you've just fastboot flashed..

Reboot... and you're rooted.

-----------

...and that's it basically... you have root, a custom recovery from which you can flash ROMs, perform nandroid backups, etc.

But fastboot is the key... learn how to use it, and you will never need to be reliant on anybodies toolkit.
