    Thanks for this. Restored back to 4.1.2 until Goole pulls it's finger out and sorts the wifi-issues in 4.2 that made my Nexus 7 unusable.

    I don't think words can even describe how thankful I am for this post, I actually thought I had well and truely bricked my Tablet.

    After A LOT of messing around and going through this step by step tutorial I finally got it to work, My Nexus7 (which is less than a fortnight old) is now unrooted & locked never to be messed with again, if it ain't broke I ain't going to try to be clever!

    Thanks again!

    Every time I try to download the link it is saving the file as a .tar not a .tgz. So all I end up with is a file that window doesn't even know what to open with.

    Can anyone help me?!?!

    I want to reset my rooted nexus 7 to factory image. Right now I am trying to set up adb and fast boot but I cannot check if it is working ( I used this guide: ). My issue is that I cannot enable usb debugging, I am running 4.2.1 and i tapped the build number 7 times to display developer options, but when i go to click in developer options it crashes with the notification "settings has stopped working", this also happens when I click on back-up and restore. After having set up adb and fast boot I opened the command prompt window to see if my computer could see my nexus 7 and it cannot - so I am going to go ahead and assume usb debugging is not enabled...is there any work around for this, I am completely stuck!

    UPDATE: all good, watched the video tutorial and restored it, all is ok. I I had read the whole thread I would have realised you do not need usb debugging

    Are you trying to flash the correct version, you don't have the 3g Nexus 7 and are trying to flash the wifi only factory image?

    If that's not the case.. Try reinstalling the drivers and switching usb ports, try to use a rear one. What system are you using?

    Default Re: [GUIDE] Nexus 7 - Factory Image Restore

    I dont know what is going on. I was using the Nexus7 Toolkit to try to flash back to stock Google Image (4.2.1) and that is when it all went wrong. Flashing from the toolkit failed, and now the device will not boot at all. I get the START button and says boot failed. So I tried to follow the steps here manually and I get the image below.

    I can get to fastboot, I am in the bootloader screen on the device, I can not get to Recovery Mode though. I tried different USB cables, flashing files individually, flashing per the guide in this thread and nothing.

    My device is completly non-functional right now.

    Please help!!!

    Reinstall drivers, use a different usb port, switch cables, etc.

    Also for what reason did you need to do the restore?

    Is it normal that it's sending 'system' <477136 Kb>.... for more than half an hour?
    Until now everything was smooth and easy, but somehow it stucked on this.

    Doing it on -> Macbook Pro -> Mac OsX 10.8 -> Parallels Desktop 7 -> Windows 7 Ultimate

    Thank You in advance. Good and kind people always appreciated.

    i'm stuck in that part too for like an hour






    EDIT (FIXED!): After hours and hours, sweat and cursing and looking all over the internet and downloading 87 different toolkits (lol), i've found the solution. I just followed this guide wich basically has the same steps but updated to the latest firmware (the files names in your guide are outdated for the 4.2.2 version). And is easier to follow.
    I hope you don't mind if i post the link. It could help other users with the same problem

    This was an awesome tutorial - worked like a charm. Unfortunately, I couldn't get Windows 7 to see the Nexus in boot loader mode. I had to do this on my Mac and it worked perfectly. Thank you!

    I got how to do it but I could not open or uncompress the file once downloaded, I have 7 zip but didn't really know what to do. My nexus 7 doesn't even go into bootloader any more it goes to the android with a red triangle on it, I hard reset no help. I have had my nexus 7 for maybe 3 months, I have rooted it and unlocked, used it as rom game emulator, but when I tried to change the system font with a google app it went into bootloader and never booted past google logo (X) screen, so I erased everything to factory reset and I think I unrooted it, but its unlocked and now when I go into bootloader it show the android on its back with a red triangle on it. It will now not boot past google screen. I tried to download factory image and everything but my nexus is stuck on waiting for device with toolkits. Please help im lost.

    You're accessing bootloader wrong.. I forget if you need to hold volume down and power or both volumes and power, been a while since I've toyed with it, but whichever you are doing try the other combination.
