Root Nook Tablet Dual Processor may be bricked

[gdecker]

I was trying to root my Nook dual core tablet and in recovery mode I deleted everything that I could. I guess that was my mistake.
Now I can only boot to recovery mode with an SD card installed. Every zip I try to install from there either gives me a Status 7
or "bad" error. g_apps installed ok from the .zip file. Nothings boots without this one card that I created with win image, the name of the file is
SD_NT.img or named close to that.

I have tried I think every zip and .img file available and always get a Status 7 and sometimes the "bad". I have tried four different sd cards and
4 different adapters. I heard that a bricked Nook was impossible but this may be the exception. Any help with this would be appreciated.

When I boot with out the card I mentioned nothing happens, just a blank screen.

Have you tried the acclaim_update.zip file? Put it on the root of the SD card, put the SD card into the NT, and power it up, and that should do a full restore back to stock 1.4.0.

I used it when I was doing the root on my NT, although mine never bricked. If that doesn't work, maybe go over this thread and see if there's anything you missed or new you can try:

Hope one of these can help! And welcome to the forums!

I tried both methods several times. With the number two method I did get the card to boot to the card system. I am still trying to get the 16GB card to show 12 GB free.

I will try these methods again tomorrow at work where the Nook is. I even purchased a Sandisk card but it acts like my other cards.

Thanks for the info.
