    To unlock the bootloader you only need your fastboot drivers setup on your computer. You don't need to have booted the phone up at all, let alone enable usb debugging. Believe me I have 3 Nexus devices, lol.

    What exactly are you trying to accomplish? A factory image restore or just unlocking/rooting?

    And I am back in business. Same day unlocked, rooted, tried to install an Urdu (Arabic script based) font ant lost the GUI. Now back to factory image and restoring apps. Thanks a lot for the guide, it was a 15 minutes work actually :P.
    Edit: though it didn't let me reboot the bootloader in last 2 3 steps to again lock it. Simple started the system, so I let it this way.

    Well, it's not working for me, it freezes up in the middle of commands. But I think that is my computer's fault, cause it's so slow. I'll hop by the town library and do the magic over there, but this is what I've been looking for for a week. Question. Is it possible to save custom images and bootloaders from a running tablet, and then use those when you (mainly me. ) screw it all up?

    Try using a different USB port, preferably one in the back of the machine if available. No to the 2nd question.

    It only has the single usb port on the back... That's how old this laptop is...... hehe.. I'm headed to the library now. I'll post about what happens there. Oh, and thanks for all the help, 2def!

    Had success on a Mac. Hanged during "sending system". Had to restart device and send "system.img" and "userdata.img" manually. But all in all, excellent information. Thank you. I like the fact that the instruction is generic and not OS specific. I should be able to apply this to future version of the Android OS.

    Hi all,

    Thanks for an amazing thread! First time root user myself and I thought I'd share a snippet of information which MIGHT be helpful. (Hopefully) as I just figured out the solution to my problem (Although it took 3 hours to do so, I'm proud of the result.)

    IF You get stuck on "Sending system.img" on Fastboot options, and it does not work - Do the following -

    Type the following, and press ENTER between each line.

    fastboot erase system
    fastboot format system
    fastboot reboot bootloader
    fastboot flash system system.img

    Do this for EACH of the partitions, then restart. Hope it helps.

    PS - Recovery will NOT go back to default. I originally CWM'd mine, and never backed up the original recovery so It's lost on my device. Don't make the same mistake.

    I apologise now, if this information has been posted but due to the fact that the PC i'm currently using only has 512MB Ram, it's kind of hard to check through forums lol.

    Hope it helped,

    Thanks for an amazing thread, you guys definitely saved my backside!

    This is great but I want to go ALL the way back to stock. Can you re-post the old 3.41 bootloader file, PLEASE?!

    Google only keeps the current, and sometimes one version prior, factory images available on their dev site. Nothing earlier than that.

    No worries... I found the files on XDA. I am NOT a big fan of 4.2.1 so now I am back to 4.1.2 and I should be happier.

    Use 7zip or winrar to extract.

    Hi, I am stuck on #8, when I type in "./fastboot -w update image-nakasi-jop40d.zip" I get the error: "No such file or directory".
    I am using a mac, and I tried to follow all of the instructions to the tee. Thanks for your help.
    UPDATE: Nevermind, I just made a dumb mistake and didn't move the file into the fastboot folder. Thank you so much for your help, you made this so easy for me! I feel like I should pay you for helping me with this!

    sending 'boot' (4606 KB)... OKAY
    writing 'boot'... OKAY
    sending 'recovery' (5106 KB)... OKAY
    writing 'recovery'... OKAY
    sending 'system' (528847 KB)... ERROR: usb_write failed with status e00002be
    FAILED (data transfer failure (No such file or directory))

    Any ideas?

    Some things I learned today:
    1 - Never used toolkits. You won't know where they failed.
    2 - Fight till the end
    3 - Be CAREFULL with stuff you're using in your rooted N7, even if it's a highly recommended app from play store like LCD Density (Yep, that one screwed me up real good).

    I almost died today when my fully functional and rooted N7 gave me only a black screen after rebooting to apply changes from LCD Density. I tried flashing stock rom twice using the same toolkit that helped me root it, but no deal. I was stuck at the "X" logo on boot forever. Guess what, like it was said on the first page, simplest solutions are often the solutions. The deal is that the commands to erase cache, recovery and system using fastboot will not succesfully complete if your device is plugged in your PC using a USB port from the front panel. I was only able to find this out when I was following this guide, as the feedback to the user from fastboot is given to the user without any kind of filter from a third-party tool. I switched to a rear USB port and all commands finished smoothly, and a tear went through my cheek when I heard the N7 first boot sound. Thank you Hollip3020 for the feedback regarding the USB port, and I wonder if our friend fenderjelly tried this... Maybe it's not too late for him, I will try sending him a message about this right now.

    Thank you all, and Remember: Use a rear USB port to connect your device to the PC. It worked for me.
