Yes, that worked! I had tried winzip before and it didn't work for whatever reason. Thanks 2def!

If your bootloader is locked then why are you doing this procedure? This is to get your device back up and running after you already screwed something up while hacking away at it, lol

After do all the steps - i can't login normal. My N7 stop in finding wifi and no more step to choose.
How can i fix that ?
I do 3 ways but nothing can sold this problem:
1) After you finish the process in fastboot and the device begins to reboot... immediately unplug it from the computer and sit patiently. See if giving it at least 5-10 minutes makes a difference. Also check the md5 checksum of the image you downloaded and make sure it matches what is given for the file on Google's site
2) After the full flash and still getting bootloops... I'd say try unzipping the main image zip (image-nakasi-jro03d.zip) and flashing JUST the system from the bootloader, i.e. only do:
Code:
fastboot flash system system.img
3) Have you tried the following:
(1) Ignoring all of the partition wipes featured in the guide. No reformatting, repartitioning. Try immediately locking and unlocking the device before you get to flashing.
(2) Then flashing the stock images
I bought my N7 to a Tablet Service - they can fix that but when i Reset it to factory - the problem return. I don't want to loose money with Tablet Service again.
My Nexus 7 can run Ubuntu 12.10 Touch Preview very well - i have just tried. ( In recovery - install 2 zip files )
2.4 - i solve th? problem - my wifi network has a problem

I'm currently stuck in the android bootloader and cannot proceed. All the fastboot commands to erase data, recovery, system etc...work perfectly, however I cannot get it to "flash bootloader grouper 4.18.img". It says "unknown partition "bootloader-grouper 4.18.img" then directly under it "error:cannot determine image filename for bootloader-grouper 4.18.img".
I've tried both 4.1.2 and 4.2.2 links, extracted everything to platform tools. Everything should be good to go I just cannot get past this part. Any help would be greatly appreciated.

Thank you for this info. I erased my nexus 7 completely and was left with no os. It was pretty easy to get it baxk up and rumming
You're actually supposed to type it like this:
fastboot flash bootloader bootloader-grouper-4.18.img
Can I use 4.2.2 found from Google's web site https://developers.google.com/android/nexus/images instead of 4.1.2?
By all means.. I probably just forgot to update this guide when 4.2.2 came out. Just remember to enter the commands matching the 4.2.2 filenames.

"Currently trying to return to stock an unlocked, Nexus 7 using a pacman ROM flashed via goomanager by my brother, but is having a lot of force errors and crashes"
I'm stuck here "waiting for device"......whenever I connect the Nexus 7 to the computer, I get a popup saying Windows doesn't recognize the device.
edit---- never reading back need to see if i installed the fastboot drivers
Ok so I have to be somewhat retarded. I booted my Nexus 7, connected via USB to PC. Made sure that USB debugging was enabled to allow adb.
I went to device manager, found the Nexus 7, updated the driver to Universal Naked Driver 0.72 found [ADB/FB/APX Driver] Universal Naked Driver 0.72 - xda-developers
It updated the driver just fine.
I now turn the Nexus 7 off, boot into bootloader."Fastboot mode" is red. Lock state - Unlocked. Whenever I connect it via USB to PC, I'm getting the uanble to recognize device error, and when in command prompt doing the "fastboot devices" command, nothing shows up, so clearly I haven't installed the drivers correctly. Am I missing something?
Edit AGAIN --- I thought I installed the Universal Naked Driver 0.72 correctly, but it shows that the Windows drivers are installed and won't let me install the UND.
I am attempting to install the android_winusb
But I get this error

One of these days Microsoft might figure out USB. I would get Wug's Toolkit from xda-developers forum for the Nexus and start over. Good directions built in. Use the pda drivers. You might have to try more than one time but the toolkit has always worked for my N7 and N10.

Reboot straight to the bootloader and try sending the pieces individually. I've had a few people do that with success, see earlier in the thread.
The boot part it is stalling at is just the stock kernel, won't brick if you boot back to bootloader and try again. Also you may just need to reinstall the drivers or even simply try a different usb port (rear ones are best). Do that first in fact

Hmm I did try moving to the rear, it did help. I'll try switching to a different rear port. Then I'll try installing the drivers all over again, thanks!

That's odd.. I would just keep trying really, maybe with a new usb cable too. You can skip the other steps when you try again and only enter
Code:
fastboot erase userdataI am also stuck here. I have done this 3-4 times and I get stuck here everytime. I have waited like 30+ minutes everytime, so I am assuming that is pretty long and something isn't going right.
Not sure what to do... :-/
Another edit: I stopped it again and I went with "fastboot erase userdata", just to see. I already tried it before like that, but why not try again.
