[Nexus 7 Q&A, Help & Troubleshooting] kanuva:
Hi all,

Since I'm new to this forum I was not allowed to post on the developers threat, so I made a new one hoping some one could help me.

My new nexus 7 arived a few days ago and I had rooted it using the Nexus root Toolkit 1.5.4. (android 4.1.2)

Than I installed a new custom rom (PARANOIDANDROID 2.2) on the nexus but I did not like that rom so I wanted to restore it back to the stock rom.

When I tried that using the Nexus root toolkit 1.5.4 I kept saying FAILED.

I think it's going wrong with the first step (Sending 'bootloader').

I'm restoring to android 4.1.2 because that one is using bootloader 3.41 and if I try to restore to android 4.1.1 I get some other error messages with the bootloader.

This is on a windows 7 x64 bit machine, I tried 2 different cables, the stock cable and the cable from my nexus s3 with both didn't fix anything and I tried every usb port (for some reason only usb3.0 ports work with my computer...)

I even tried restoring to stock + unroot on 2 other computers (win 7 x64 and win 2008 r2 x64) and both are stuck at: sending 'bootloader' (2092 KB)...

So basicly I do get in to fastboot, but I can't get any further than that, Recovery mode gives my an open android with a "!" in its "belly" and the option "Start" get me stuck at the bootlogo from the custom rom (PARANOIDANDROID 2.2).

I hope you guys can help me with this anoying problem.

Btw. I'm sorry for my bad english, this isn't my motherlanguage and it's late.

EDIT: the tablet is stuck on "google" with an unlocked lock logo when I try to turn it on.

EDIT2: On windows 8 x64 it is saying too many links.
