hey guys i did a native install of ubuntu on my nexus 7 without multirom and now want to ditch it for android again. i see that it didn't get rid of twrp and i can still get into it so if i just did a full wipe including data and then flashed a rom would i be good to go or is there a certain precedure i should be following?
I would try flashing an official CM10 Rom as they typically have better flashing procedures to make sure the partitions are setup right and stuff.
I'd think you'd be OK though.

Id use WugFresh's Nexus Root Toolkit to reflash stock. It walks you through it, and that way it will make sure the file system is set up correctly. Then just root again.

Didn't really want to redo everything but might as well since Ubuntu wiped it out anyway. Good thing I made a backup thanks dude

I would like to do a complete back up of the kernel, rom, apps, data, etc. and move it all over to another Nexus 7.
Is it possible to do a complete backup and restore via USB? Backup to Desktop, and then restore into the new 7?
If so, what is the best way?
Thanks!
If you use an older version of cwm (pre 6.x.x.x) it will create a single backup file instead of the current system with the blobs folder. However I would be very wary of moving one backup to another

Let me explain. I am replacing my Nexus 7 with a new one, and don't want to have to set it all up again because it's perfect right now
No clean way to do this? I have to just rebuild it all over again on the new 7?
If you are rooted, you can almost do it that easy, but you would need to unlock and root the new device first, install recovery and then move the saved nandroid backup to the new device and use recovery to restore that and you would have a copy of your old device on the new one.
The last time I did that,I was up and running on the new device in about 15-20 mins.

If you are not rooted, there is another method, but I've never actually tried doing it, so I don't know how well it works.

Thanks. That helps alot. I am rooted so should be good to go. I was not aware that the nandroid file could be saved and restored to a new device.

On my Android phone, Nandroid does not back up the internal (/emmc) data nor the /sdcard data. Does it back up EVERYTHING on the Nexus 7?
I see a couple of different tools here to unlock and root my Nexus 7. What are the differences between them?
I do not want to flash ROMs; just unlock, root and install cwm recovery.

Don't use tools for rooting with the Nexus devices, it's useless in my opinion. Try to understand the basics behind rooting, recovery and fastboot, do it manually and you will be able to help yourself even if something is not working as expected.

Even though I know how fastboot, recovery and rooting works, I still use this tool without any of those commands. And it serve the purpose for me quickly. Of course using such tools will not stop you from learning more afterwards.
I wouldn't say its useless.

then you should br helping out all the people that mess up their devices afyer using toolkits and dont know how to fix it. i havent seen you help out, yet you are still recommending toolkits. why is that?
I used the steps outlined at http://rootzwiki.com/topic/28544-guide-nexus-7-bootloadersrecoveriesrootback-to-stock/ to guide me.
I must say it might not be trivial for the non-software-developer types.
I was a Java developer for many years, so I didn't have much problems setting up Java,
Android-sdk, etc.
My N7 was recognized by adb when booted normally, but after I flashed cwm, I could not do 'adb shell' to mount the /system partition and rename the recovery-from-boot.p file to prevent the recovery from getting reset to stock each time.
I ended up installing the ROM Manager app to enable me to boot into cwm recovery.
I have done the obligatory cwm backup. I believe this is the nandroid backup?
Edit:
I used my Linux box to re-flash the bootloader and cwm recovery images to the Nexus 7, and I could 'adb shell' and rename the recovery-from-boot.p file. So I'm all set now.
I just needed to run 'adb start-server' and 'fastboot' using sudo, so it might have been a permissions issue on my Windows box.

I used Wug's Root Toolkit. Both of the toolkits seem good, but that was just the first one I saw. The Wug's Toolkit is an application and the other one is in a CMD.

Absolutely brilliant ToolKit, very simple, fast and works like a charm.
I rooted my N7 with this, and had no issues to date.
Only took a couple of minutes.
BRILLIANT!
Looks like I'm not all set, after all Today, right before I plan to take the JB 4.1.2 OTA update, I notice my tablet won't boot into CWM, like it did a couple of days ago. I did rename the one file and things looked normal. What could have happened to my CWM?
Edit:
So there are 2 files that need to be renamed, not 1?
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
And there was a bug in JB 4.1.1 that prevented booting into cwm recovery unless the device was plugged into USB??

I re-flashed the same cwm recovery img, reinstalled the same su zip, and I'm back to normal
Gotta watch out for those OTA updates, I tell ya.
Use the fastboot commands
Good to see you alright!
This is like asking "Should I get an automatic or manual car?"

In the early days, automatic transmissions were more problematic and much more expensive. Today they are pretty efficient, even though a manual transmission gives you better control over the car, which most people don't really need for everyday driving.
If you frequently get stuck in stop-and-go traffic, you'll wish you had an automatic transmission.
Look at these lazy people..

Yes there was a bootloader bug on the nexus 7 and most people could not boot into CWM recovery without plugging it into their computer.
I however used TWRP back then [have since switched back to CWM touch, now that the bug is fixed] and had no issues. Now I have no issues with CWM touch, I can boot it directly from fastboot menu, or "reboot -> recovery" when booted.

exactly what I would have done! sounds like you're getting the hang of it. and yes, I definitely recommend manual rooting/fastbooting to a toolkit.

Yeah, that's what I'm saying. They both have their ups and downs. If you're willing to learn a little about how Android works and learn some adb and fast boot commands then you should definitely do it manually.
If you just want to be a "1337 Haxorz" and aren't willing to learn then just use a toolkit.
OK, just one sub-question on rooting. I see no real reason to root except maybe to get more tablet interface than nexus has. Kinda like when the wifi indicator is at the bottom, since there are those !$#$$ back/home buttons already and a lot of wasted space Anyways, the question.
I bougth N7 16Gb and upgraded via forced OTA to 4.1.2. Do all these root methods work with 4.1.2?
Thanx,
D.
Hello!
First post here and let me start off by saying i have no experience what so ever with rooting or custom roms . Purchased a N7 today that the seller said is running a custom rom. The wallpaper says clean rom so maybe that means something. It is running 4.1.2 and is prompting me to update....i assume to 4.2. My question is can i update? If so where does that put me? Will the update put me back to stock or is the device still rooted or running a custom rom?
Hey...i warned you...i know nothing about this but this appears to be the place to figure it out.
I have been reading for quite some time and could not find a clear answer.
Thanks in advance!!
You probably wont be able to update, you would have to flash back to stock 4.1.2. first .It does a check of certain stock files and system apk's before it will update,you would be better off going to https://developers.google.com/android/nexus/images and getting the full stock 4.2 and doing a flash using wugs,there are alot of tutorials on here for directions.
Flashing the stock image over the device is fairly simple. I'm not adv savvy at all, but the wugs toolkit works SO LONG AS YOU GET YOUR DRIVERS SET UP RIGHT. Wigs also requires you to be running Windows. But wugs toolkit will allow you to flash the factory OK mage and then root it so you can use stickmount and ad away and such.-Ara

Thank you both....I will continue reading and see if I get enough confidence to mess with it.
Hi I have a problem with my Nexus 7 (32 gb wifi only version).
My son in his infinite wisdom decided to install ubuntu on the tablet.
I went to try and restore this back to the android version but all it did was to wipe off ubuntu itself
I then went on jayceooi.com and used the nexus toolbox to see if I could reflash the images etc.Howveer although all the files were downloaded I canot get the laptop to recognise the nexus itself (even though it sems to charge the tablet). There is no menu at all to check whether or not usb debugging is ticked or not..
Im now left with the tablet without no apparent operating system. At the moment all it shows is the green android with fastboot mode but when I hit start it says booting failed.
Could someone help please before I do any more damage and I brick it completly (although I may have already done so)
thankyou for any help

Yes it can do restore back to stock. Just follow the guide to unlock bootloader so it can flash stock image then just re lock bootloader. It covers the process in op.

Ok thanks all. Seemed to be doing everything ok but its been stuck on"waiting for your device to finish booting back up" for about 30 minutes now. It did say it would take 5 to 10 mins but should i carry on waiting or abort and start again do you think?
thanks
I would reset it see if that helped

If your son re did the partitions for Ubuntu that could have messed things up pretty good. I have only had my nexus for a few days so I couldn't tell you how to fix the formatting quite yet. I would search around on how to verify and correct the partitions if needed.

I have a N4 which was unlocked and rooted after updating to 4.3. I figured, I'd give Franco Kernel a shot so I proceeded to download the Franco Updater from Google Play.
Selected automatic flash and reboot and now it's stuck in a perpetual boot state. I attempted to proceed with a hard reset through the recovery mode; using ClockworkMod Recovery. I wiped my data, cache and dalvik cache and then went on to reboot system.
Up till' now, my N4 is on the boot Google screen. I tried doing the above steps multiple times but the results remain the same.
I'd appreciate if any help is directed on how I would be able to reset my device to factory settings. I don't mind going through the unlocking and rooting process again; I just need it to get through the boot screen
Go to the bootloader and run this tool: https://developers.google.com/android/nexus/images#occamjwr66v
It works every time.
Something went wrong with the flash for sure, I can tell in many ways so wiping will not help anyway unless you flash an other kernel.
This will wipe EVERYTHING so I don't know if it is worth flashing or flash an other kernel, you choose.

Make sure it is Mako/Occam.
What ever android version you chose extract the file twice until you get to the contents and run flash_all.bat, if the script says that you are missing the Fastboot file you have to get it from the SDK.
Make sure your device is on the bootloader which is unlocked.

I'm guessing this doesn't work on Mac? Because I'm currently on my Mac machine at work. If it's only for Windows, I gotta try it when I get home later.

There is .sh has well which should work on Mac BUT you have to go though a lot with drivers.

Just to be clear, this solution is just to flash your device back to stock.
