Thank you again for the write up. Just flashed my 7 back to stock and locked it. I had really bad screen lift on the left and decided to go the RMA route. My new one is flawless and used your guide again to unlock the new one :D

Thanks for the guide on restoring back to stock, first time I ever had to do it but you made simple, couldn't have been more than 10 minutes for the whole process.

help! I'm trying to restore the n7 to stock and this is what I get:

new-host:~ DSRothman$ fastboot-mac -w update /Users/DSRothman/platform-tools/image-nakasi-jro03d.zip
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
--------------------------------------------
Bootloader Version...: 3.34
Baseband Version.....: N/A
Serial Number........: 015d2109ec30121a
--------------------------------------------
checking product... OKAY
checking version-bootloader... OKAY
sending 'boot' (4890 KB)... OKAY
writing 'boot'... OKAY
sending 'recovery' (5234 KB)... OKAY
writing 'recovery'... OKAY
sending 'system' (438656 KB)... ERROR: usb_write failed with status e00002ed
FAILED (data transfer failure (No such file or directory))

I downloaded the image direct from google twice...tried re-erasing the system and tried unzipping and flashing the system partition on its own...what am I doing wrong?

that didn't work but I think it was a USB issue...the error was related to usb communications so I downloaded sdk to my wife's PC and set up there...ran the same commands and all good. Thanks though!

I think it's a little finicky with which USB port you plug it into. I had to switch to a different port to get mine to go back to stock. Not sure why.

Yeah, it's weird...both Ports on my MacBook were nogo but on my wife's HP, it was all good...it's just weird that everything but system flashed fine. you would think that if you could flash one partition, you could flash them all...

When bringing this device back to stock, are there any flash counters or nomenclature that says "re-locked" vs. "locked"?

Nevermind i figured it out thanks to google! just in case anyone else has the cant load recovery problem. you have to open the command prompt from inside the platform tools folder (shift button and right click the mouse) otherwise fastboot wont know the command path to get the file. Got her up and running unlocked,rooted, and twrp. IT was really pretty easy. I dont know why I let adb scare me for so long! now i gotta go delete these tool kits.

hi all. ive run in to an issue with the recovery. cwm cant mount the sdcard so i cant flash any roms. ive also used twrp and it doesnt seem to actually install the roms when i tell it to but it goes through the motions. now im stuck with an n7 that wont boot past the google screen. going to try going back to stock but if anyone else has a suggestion let me no

restoring to stock fixed the issue with not booting. now i need to find out whats up with the recoveries. any one else have sdcard not mounting on cwm?

+1. It's not that hard to unlock/root devices without using a toolkit. I think toolkits just cause more problems than they solve, ultimately.

I'm not sure if it was mentioned in this thread (too lazy to read more than 4 pages) but most people will be unable to access recovery on the 7 via the Vol - + PWR buttons using either TWRP or CWM. This appears to be specific to the 7. Yes, there are multiple apps you can download that will allow you to boot into recovery with no issue. The problem is when you bork your OS and you need to get into recovery using the buttons.

The work around is to plug your 7 into your PC. When you do this, you should be able to get into recovery by using the buttons. I tested this multiple times with both TWRP and CWM and it worked every time. Not sure if you want to add this to the FAQ's for the 7.
Same here. When I want to get into recovery from bootloader it just sticks at the Google logo. At first I thought my CWM might be broken but via an app or "adb reboot recovery" recovery just starts fine.

However when the tablet is plugged into the PC while in bootloader, there is no problem with starting recovery.

Is there a way to get Recovery to stick? It truly is annoying having to connect it to my computer all the time, lol. The instructions here and on the official site don't work.

I've read this in several places. But if you go into terminal
su
reboot recovery

It works for me. Or if your ROM has power controls you can just do that as well

This also works for me. But when your system doesn't boot, you need to get into recovery from bootloader. And therefore it needs to be plugged into a PC or else you get stuck at the Google logo.
