    and when I boot into the bootloader there is no fast boot option. restart bootloader, recovery mode, power off and start are the only options I see

    Just a heads up, not sure if it was already covered, but i found on my system that the files won't transfer properly over adb if your connection is USB 3.0

    A very big Thank You to 2defmouze and dmmarck for this excellent tutorial. Made a full recovery from the mess I made trying to install CM10. Think I'll stay with stock Nexus 7 for awhile.

    My 2013 N7 was bricked after the latest update. Before I did anything, it would go into fastboot, or stay on the nexus screen, but that's it. I managed to get through all the steps right up to flashing the actual factory image, which is where I get an error. It just says "failed to load: no error."

    Any suggestions?

    *****Ok, ignore below, i left it for about an hour and came back and it had flashed 4.2.2 successfully and is now getting the 4.3 update via OTA*****


    I've been having an issue restoring stock on my 1st gen N7 Wifi as well.

    I was using Wugs toolkit to reflash stock and unroot and it errored out due to bootloader version (mine is 4.18) so i tried manually and i get this error

    Code:
    sending 'bootloader' (2100 KB).
    OKAY [  2.212s]
    writing 'bootloader'...
    FAILED (remote: (InvalidState))
    finished. total time: 2.355s
    SO after this I tried flashing factory 4.2.2 since that is what the rom i was using was based off and everything goes fine and then it just hangs on sending the system files.

    I have tried multiple full wipes and reflashing it all manually now but it always hangs on sending system files.

    I can get into fastboot and that is all, can't even get into recovery.
    I have also made sure Im not using USB 3.0.

    and heres the log from trying to flash 4.2.2

    Code:
    c:\FLASH>fastboot -w update image-nakasi-jdq39.zip

    Worked a treat,....OMG, thanks guys,...thought I'd bricked my N7!
    Had to manually reboot into bootloader rather than use dos command after going into platform tools, then flashed the image.
    I'm an absolute novice, and followed and watched the guide step by step.
    great work!!

    I have a Nexus 7 that only boots in bootloader mode and from there won't do anything. Trying to boot gets the message "booting failed".
    I tried installing the factory 4.3 but 'checking version-bootloader failed' version is 4.18 update requires 4.23. So I tried installing factory 4.18 which worked but the tablet still only boots in bootloader and nothing works there except the "booting failed" message.
    This machine was on Rootbox 4.2 version one successfully but version 2 started system files crashing so I decided to go stock. Using Wug's toolkit although I appreciate the fastboot commands you have assembled.

    Hey guys, need help. I am trying to restore the factory image of my N7 but the image write fails, I've tried to do the cmd thing but it doesn't seem to work. Is there any other way to flash the factory image????
    The present condition is that my tablet boots into bootloader and then to recovery but there ain't no OS.
    I read somewhere that a guy mounted a Usb via OTG through the recovery and then flashed the factory image. Should I try it? Will it work???

    Hi, sharkxelectronics...

    Never heard of this problem occurring with userdata before... if it fails anywhere, it's usually with system.

    Try disconnecting your Nexus 7 from your computer and reconnecting it to a different USB port... reboot the bootloader and try again.

    Rgrds,
    Ged.

    Mac user here. Every time i try to update my bootloader, it says it updated successfully when i flash it but when i reboot my bootloader, It is still on version 4.13. so i am not able to restore a factory image. Is there anyone else that has had this issue? what am i missing? I would just restore an older factory image if possible but i am not able to find one that is compatible with the 4.13 bootloader.

    edit: flashing an older factory image worked. weird. but i got where i wanted to go.

    I got to the point of flashing the factory image but when I do, fastboot crashes and I get an error message. Can't seem to get fastboot to stay up during this step.

    Hey there!
    I have the Nexus 7 (2012) WiFi and a big problem! After updating to KitKat, I got a bootloop. :-(
    I followed this guide to make a complete reset. Everything went good! I also used the brand new image from today (image-nakasi-krt16s). I did everything exactly like described here but still have the bootloop. After step 10 (fastboot reboot), it rebooted, showed the white Google, the 4 circles came, after a few seconds, the N7 rebooted again and is booting now for a long time. What else can I try?
    I hope, that someone can help me!

    UPDATE: I made several more runs of this guide. Now it works again. What I did/changed: I used a different usb-cable and plugged it directly into my PC. Maybe that was the reason, but I'm not sure.

    After my Google Nexus 7 has stayed stuck on the "X" screen I've been trying to use Google nexus 7 toolkit 5.0.0 to install the factory image. Haven't succeeded yet. There's a question and an issue that I haven't found answers to that may or may not be part of the problem.

    1. I haven't been able to find information that tells me just what the hell factory image I should be installing. I see the list available on the toolkit. I've seen this list. Seems it should be one of these: 4.1.2 (JZO54K) 4.2.2 (JDQ39) 4.3 (JWR66Y) 4.4 (KRT16S)
    It's a refurbished wifi, on the box is what seems to be the model: TB-AS-NEXUS732S
    in the bootloader there's this info: product name: grouper, variant: grouper, hw version: ER3, bootloader version: 4.23
    I see warnings in various places that you can damage or brick your nexus if you install the wrong image, but no information on how to make sure this doesn't happen. If I'd have known a Nexus 7 could just spontaneously stop working, I would have made a note of the android build number before it happened, but I didn't.

    2. I've gone to step 9 to flash the image about a dozen times, and EVERY time I get the message,

    "checksum of the image you want to flash: [xxxxx...]
    checksum of the image should be: [xyxyx....]
    the checksum of the image does not match the checksum of the Toolkit database."
    Could the image have gotten corrupted every time? Also, I've done a search on the google images page and not a single time has the "should be" checksum matched ANY of the checksums listed for the factory images. That doesn't seem to make any sense.

    Also, I've tried just using the fastboot recovery mode to wipe/restore, and I'm still stuck on "X".

    Any help is greatly appreciated.
