Fix for bricked nooks from CM7 "formatted sd"

---

for this fix, you will need to have a CWM sdcard ready and waiting followed by and drivers properly installed for your tablet.

YOU MUST have CWM running from sdcard to fix this issue. Otherwise nothing will happen.
instructions to install to sdcard are here (I suggest using windows)

Needed files for download:
just download this zip and run the script while booted into cwm from sdcard.
download it here.

Instructions: Boot from sd (don't worry, it will work), ensure sdcard is mounted, and then you just run the fix.bat from the computer after extracting.

Credits: Succulent for the xloader image
Fattire for the idea that it might have formatted mmcblk0p1 (which it dead instead of mmc1)

You're welcome.

Might want to add that the cause of the "brick" appears to be that CM7 is confusing mmc1 and mmc0 and instead of wiping the first partition of the SD card, it's presumably wiping the first partition of the emmc, which contains the x-loader.

I already have said it.

Ah okay... well glad everything is fixed now.

Bowing head in shame here...... Rookie mistake!


Looks like we have to make a bit of a tweak to the system then do some testing.

New download link due to a small scripting error.

Need help

Hi Indirect. I see that you have fixed your NT. I did not use sd i did install cm7 internally but i did format all the mounts . And now it just restarts in CWM. What should i do. Any idea please

Well guys, I'm still having problems. I ran the brick fix before you updated it - didn't work. I then re-ran after you updated it - still didn't work. It'll boot to CWM from SD, but won't boot to any ROM. Tried re-installing CM7 (didn't work), then I tried the Nook141root.zip which supposedly installs the BN 1.4.1 from CWM (also didn't work). Tried re-running the brick fix a handful of times after and before installing each ROM with no luck. Then I tried running it without installing a ROM. Tried the brick fix then I tried the BN 1.4.0 restore file. I tried on multiple freshly formatted SD cards and I even tried on a computer I was working on with a fresh install of Win7 with a fresh install of the drivers just to rule that out.

Before all this I had CWM and CM7 installed internally - if that makes a difference. Ideas?

Edit: More info. When trying to wipe data/factory reset in CWM I get the errror "E:format_volume: make_ext4fs failed on /dev/block/mmcblk1p2"...this occurs right after rebooting from the brick fix.

Edit 2: More info yet...in the brick fix I'm getting the text "error: device not found" twice right after entering "y" then again a handful of times later. Is there anything special I have to do in CWM to get it to detect it? I have sdcard mounted...

Im geting this and then my nt restarts by itself and then im back in cwm again so nothing is fixed.

What do you have mounted to get it the fix to detect the tablet? Does it matter?
