[Nexus 7 Android Development] Milamber33:
If the OTA has a newer bootloader, then yes, it will fail if you don't have the one that matches your current build. If it doesn't, then I think it should be fine. And if the OTA doesn't work, you have 3 options. You could put your bootloader back to the matching one and try again, you can use a custom recovery and skip the bootloader part of the OTA, or you could wait for a full system image and dirty flash that.

If you have some sort of security program that can lock you out of or wipe your device, and it requires root, then I'd say disable it while doing the update just to be safe. Probably without root it wouldn't be able to do anything, but it's better to be safe than sorry.

And there are methods to keep root through an OTA update (search for OTA Root Keeper), but I've never used them personally. Another thing to check is whether or not the existing root stuff will work on 4.2, or whether or not they've been updated yet.

Bottom line, if you absolutely require root, it would be best to wait a couple of days to see how others go and get a known good update path.
[Nexus 7 Android Development] dmxsoulja3:
Thanks Milamber33, I went ahead and disabled the security features, now that Google has posted the 4.2 builds online, I should be able to go into fastboot and sideload that zip right using ADB? When you do these updates does it automatically update the bootloader as well? Then just wait for the toolkits to support 4.2 and I can root it again.
[Nexus 7 Android Development] Milamber33:
If you're download the full system image from Google, extract it and it will contain separate files for the radio, bootloader, system, etc. Just flash the ones you want. Don't flash userdata.img or it will wipe your device.

If it's the update.zip on the other hand, just use a custom recovery. Not sure of the exact process to bypass certain sections, but I know it can be done.
[Nexus 7 Android Development] mskip:
Is there a full 4.2 google image available? I have updated to 4.2 and now adding root support to the Toolkit. Also adding some information on enabling developer options on 4.2 as google are trying to be sneaky and hiding it lol.

OTA or the link that someone post a few posts ago?
[Nexus 7 Android Development] FreakyFreakGA:
Now if I used the tool to revert my bootloader back to 3.34 or whatever, is the only way to revery back to 3.42 or what not to do a full reinstall of the original 4.1.1 OS through this toolkit?
[Nexus 7 Android Development] mskip:
You can just grab the newer bootloader from the development forum both 4.1.1 and 4.2 bootloaders have been posted, then flash them via the toolkit but theres really no need to as 3.34 works fine.

Mark.
[Nexus 7 Android Development] mskip:
The only way of getting 4.2 at the moment is to have a stock 4.1.2 image on your tablet (with stock or custom recovery), download the google OTA update which is basically just a patch to 4.2, copy the zip file (DONT UNZIP IT) and install via recovery.

GOOGLE NEXUS 7 TOOLKIT AUTO UPDATE V3.8.0 AVAILABLE [13TH NOV 2012]

Changelog:

+Added FULL support for Jelly Bean 4.2 (apart from google stock factory image which I will add when released)

+Added Stock and Insecure boot images for 4.2 for proper support

+Added more to the 'Device Information' Screen

I tryed rooting initially using the 4.1.2 boot image and it doesnt boot fully into android so the 4.1.2 image isnt compatible with 4.2. Furthermore the busybox procedure didnt work properly so I included stock and insecure boot images in the update for proper support.

Updating to 4.2 will also enable the restore recovery files so its best to use the 1-CLICK which will rename those files in the process.

For users without the Auto Update feature I will try my best to make a full version tonight or tomorrow. I have family commitments tonight so cant do much until late tonight. I really wanted to wait until the stock google images are released but I will have to add those when they are released.

Android 4.2 is a very very nice update especially the lockscreen widgets :D

If you are using the version in the first post you can still root fine by flashing custom recovery, pushing the root zip file to the Internal Storage and installing root via recovery. Like I said I will build and publish a full up to date version as soon as I can.

Mark.
[Nexus 7 Android Development] sorcio46:
Waiting for that :D
[Nexus 7 Android Development] mskip:
If you flash a google factory image (full firmware) then your userdata partition is formatted and you will lose anything in your Internal Storage.

If you flash the OTA update then you will not lose any data. You do however need to be on a Stock 4.1.2 JZO54K build to update to 4.2 so if you are on a Custom Rom you will lose your Internal Storage whatever you do.

If you do have a Stock 4.1.2 Rom and Custom Recovery on your device then you can do the following:

1. Download the OTA

http://android.clients.google.com/p...signed-nakasi-JOP40C-from-JZO54K.094f6629.zip

2. Copy it to your Internal Storage

3. Reboot to Recovery

4. Install the above file to update to Android 4.2

Key point to put in your dialogues.

To get to developer options in 4.2 you need to tap on the build number under about tablet 7 times, then they'll appear in the menu.

If it's a fresh install, you'll need to enable USB debugging for adb access

both options "completed successfully", but I have no root :crying:

SuperSU option worked

[Nexus 7 Android Development] Albadros:
I'm totally losted for rooting ^^ (It was much more easier on my SII ^^)

I bought yesterday a nexus 7 32Go, it's on 4.2 now

How to do :

I just have to download and execute the application on the first post.

Install the drivers for XP with the option 1.

Enable USB Debugging on my tablet

Do I need to install SDK android tool ? :confused:

and next ? which option is working for rooting 4.2 ?
[Nexus 7 Android Development] mskip:
I added it to the FAQ last night but yes I realised I need to add it to the instructions in the toolkit.

Im going through a fix list this morning so will push an update soon.

Mark.
[Nexus 7 Android Development] mskip:
I guess 4.2 has changed the requirement for root probably because of the addition of the Multiuser feature. I will update the SuperSU files and set the root method in 4.2 to SuperSU ONLY for now until ChainsDD updates Superuser.

All fixes will come this morning.

Mark.
[Nexus 7 Android Development] sean.trinidade:
Chainfire updated SuperSU last night (see here) - is it possible to use this instead?
[Nexus 7 Android Development] edbertin:
Mark to be honest i was using superuser since i got my first android device in Jan this year (RAZR), but i realized after i got my N7 i prefer supersu. So i changed this also in my sgs2. i think SuperSu is more polish icon design and more friendly UI, etc...

So i stick on SuperSu.

For those who still not getting root, my post on few pages back has the steps to do it, ppl are lazy to use the search in thread :P.

Very simple (this applies only for toolkit 3.20 no-donators and before Mark update to the new version):

First download Super Su from here and put someplace in your N7

Go to fastboot in your N7.

Use option 10 in Toolkit. This will temporay install a CWM or TWRP. when your N7 got to recovery menu, just hit install zip from SdCard, choose the supersu file.

And its done..

Easy piece !!!

Hello;

This tool is excellent and I used it to root and unlock the bootloader on Android 4.1.2

Yesterday, I flashed 4.2 on my Nexus7 and restored Root with OTA Root Keeper and it seemed to work but busybox doesn't seem to be here anymore, and when I try to download it from the Play Store it says it cannot run the shell command. Any advice ? Thanks.

INFO

Just need to check the Internal Storage Backup/Restore procedure before pushing a new Auto Update (its the only way I can do it until everything is stable).

Things have changed AGAIN in 4.2 and the Internal Storage is in a '0' folder which gets backed up along with all data. I need to make sure that restoring the backup will push everything to the right location so it can be seen properly. Hopefully it will be fine but if not its a relatively easy fix.

4.2 is a much bigger update than previous versions (to work into the toolkit)..

[Nexus 7 Android Development] ThurstonX:
restoring 4.1.2

FINALLY I can post in this thread! ;)

Mark, just gotta say thanks for all your work. And ask the question...

what's the best way to restore 4.1.2 using your toolkit, and is it possible to do so without a complete factory image reinstall? I have backups of all things 4.1.2 (prior to flashing 4.2): apps + data, the media files and a Nandroid backup, so I know I could get it all back, but I'm curious if 4.1.2 can be flashed the way 4.2 was, thus retaining apps, data, etc.

I posted this question in a different thread, got an answer which seems reasonable (flashing specific image files, but not others), but which requires installing the SDK, etc. And while that's probably a good thing to learn, I'd like to try some method using your toolkit.

I downloaded the 4.1.2 zip file that can be flashed using CWM (so much smaller than the 4.2 file), and I also downloaded the full 4.1.2 Factory Image tgz from Google. So I have those resources on hand. I'm wondering if the file system changes to 4.2 make a quick restore of 4.1.2 feasible.

I'm an Android noob eager to learn. I'm also happy to experiment a little and provide results, so long as I can do a factory reset to 4.1.2 should things go pear-shaped.

Cheers.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Quick thought: would restoring the Nandroid backup be sufficient, or are there other elements that also need to be restored?
[Nexus 7 Android Development] mskip:
If you flash a 4.1.2 rom via custom recovery then it will flash everything needed and retain your data so nothing should be wiped. There is a setting when flashing the stock rom that formats the userdata partition (efectively resetting the device) but I will quickly add an option to leave that format off and see how it affects the system. It should be fine so I will do it and add it to the 3.8.2 auto update that will be coming soon. If you dont have the auto update feature I can send the commands to try it.

restoring 4.1.2

Ah, Mark, you da man! I do have auto update, so I will wait for 3.8.2 and test it out with the stock ROM. Ain't beta testing fun ;)

Quick noob question on flashing a 4.1.2 ROM via custom recovery. This is the same process used to flash the 4.2 zip file, yes? I used

094f6629314a.signed-nakasi-JOP40C-from-JZO54K.094f6629.zip

to get 4.2. Copied zip to sdcard, flashed using CWM. So to get back to 4.1.2, I could copy

03a4eaf95f73.signed-nakasi-JZO54K-from-JRO03D.03a4eaf9.zip

or some other custom 4.1.2 ROM to the sdcard, and then flash that using CWM. Or am I missing something? I don't think so, but still learning. ANYway, that's just for my edification. I will happily test the new feature you're adding to your toolkit to use the stock 4.1.2 ROM.

If you're on 4.2, need root, and have CWM, you can put the latest SuperSU zip on the sdcard, reboot into custom recovery, and then flash it. That's what I did when the 4.2 "fix-root" option didn't fix it.
