WARNING: I am not responsible for anything if you damage your device while using this guide. All information in this guide is tested to be working on NOOK Tablet. This will void your warranty on it as well.
Download the CM7 file here. Assuming you have already followed this guide (if you haven't done so then please leave this page and go do that) and created a bootable CWM sdcard, follow the instructions below to flash CM7 now:
1. Mount the sdcard you've been using or plan to use as your everyday storage to the computer and transfer the CM7 file onto it. Now take it out.
2. Now insert the sdcard you created in this guide into the Nook Tablet and Power the NOOK Tablet off
3. Then power it back on by holding the "n" and the "power" button together until it turns back off again. (do not let go of the two buttons until your device is fully off)
4. Now power it back on normally with the power button alone. You will see a picture of an "N" on the screen followed by a brown box with a white background. Lastly you should see "CWM booting up".
5. Once you're in clockwork recovery, switch sdcards back to your everyday one that you put the CM7 file on and then BACK EVERYTHING UP!!! Go to "backup/restore" and select backup.
6. When the backup finishes, go back to the main menu and follow steps below to flash CM7:
-Install zip from sdcard
-choose zip from sdcard (If CWM hasn't recognized your SD card you need to eject it and re insert
it once or twice, sometimes you need to go to mounts and unmount SD, pop it out and back in then
select mount sd)
-choose CM7_NT_alpha12_Public1.zip
-scroll down and select Yes - Install CM7_NT_alpha12_Public1.zip
-sit back for a couple of minutes while the installation is carried out
7. That’s CM7 installed, next you need to prepare the rest of the device
-press your power button once
-scroll down and select wipe data / factory reset
-you're ready to roll! scroll up and select reboot system, initial boot can take a while and does pause
for a short while on the black screen between flash page and CM7 Animation, enjoy CM7 for Nook
Tablet!
NOTE: To format back to normal the sdcard I burned the recovery onto I just put it into my phone and formatted it in the settings. I haven't tried using the Nook Tablet itself to format it back to normal but if I do try it I'll update this blog with the results.
