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

    Tutorial great thanks. All very clear and easy to follow. Unfortunately my issue must be a hardware failure. Originally stuck in a boot loop with the google logo. Did the usual soft/hard reset, deleted cache (Wasn't worried about losing data) but no joy. Followed the tutorial here to the letter with no un-expected faults. On final reboot still stuck with google logo. None the less, learnt a lot from here so thank you. Looks like a call to ASUS though :-(

    After following the guide (which you did already according to your post).. Lock then unlock the bootloader again, in fastboot/bootloader mode using:
    fastboot oem lock
    Confirm it has locked
    fastboot reboot-bootloader
    Then
    fastboot oem unlock
    And confirm it on the device.. Then unplug it and let it reboot.... Might clear out whatever the last issue was

    Thank You very much! So much and many erroneous and seem to be intentionally misleading guides, how to's etc. I stumbled across this after being unhappy with my rom (remain unnamed) and could not find a guide that was worth a damn, but I read yours through one time and felt positive. It took me about less than 30 minutes to have my beloved tablet back. Thanks again and kudos to the other contributors

    I use to reset my Nexus 7 back to factory too. What I found a lot easier is to get the free app CLEAN MASTER....I use it constantly. You'll be surprised how much crap stays in your files...lol

    When i do fastboot flash bootloader bootloader-grouper-4.18.img i get a out of memory error and my command prompt crashed, as a result of this i no longer have a boot partition on my nexus and i cannot do anything with it. Is there a way to fix this?

    EDIT: I managed to fix it by completely removing everything to do with the nexus on the driver side of things, this seems to have fixed it.

    Lol you are just forgetting to write "./fastboot-mac" as the command and instead writing just "./fastboot" ..... (see bolded)

    The thing about the pipe properties doesn't appear to be affecting anything.. I did a bit of research and confirmed some mac users have seen that and it doesn't adversely affect it.

    thank you buddy, I've realized that late, after I used one of the toolkits for Mac and I solved the problem, nexus IP and running , this post is saved and am sure it will come in handy at some point as am sure I'll use it sooner or later.

    Hi, just bought a Nexus 7 with no power hoping it would be a simple fix since most of the time it's a battery issue, but the only thing I can get it to do is show up as "APX" or "nvidia usb boot recovery driver for mobile devices" after drivers are installed by windows. Is there any way to flash it from this or did I just waste my money? I mean, I can go into work monday and try to find out if there's a way to fix it since I work on Asus tablets, and there's a google line that only works on Nexus, so we'll see there too I guess...

    One day some of the apps of my nexus7 were forced to close, so i try to restart the nexus7 .
    however, it cannot boot pass the x logo from that time, even i force to restart it .

    So i am just think should i follow your guide...
    just one thing i am afraid of ...
    would these kind of changes causing the loss of the warranty?
    and if i fail in the part in the guide would it cause me cannot open the tablet again because of doing the following steps?

    Only follow the procedures in this guide if you are having a software issue caused by rooting/hacking/flashing something. This is not for any other issues.

    @NoOneSpecific thanks for posting the solution you found for that issue.. Makes sense to have that command in to flash the radio for the 3g enabled version. I'll update the OP when I get a chance.. Wouldn't have noticed myself as I have the wifi only grouper.

    Guide updated with links to the new 4.3 factory images and instructions should be updated accordingly. Also threw in some edits to try and make it clearer the extra step/changes that one should follow if using a 3G/HSPA+ Nexus 7 versus a wifi only model.

    Try just sending the system, after unzipping it and erasing the part that failed to send:
    fastboot erase system
    Then
    fastboot flash system system.img

    Did you try switching to a rear usb port? Also if you didn't use 7zip to unzip the archive try again doing so.

    No rear use port as I'm on a netbook. I did use 7zip to extract file.

    I would try another computer for this.. Possible the netbook just won't cut it.
