There is a known boot loop issue when installing ClockworkMod Recovery (CWR) version 126.96.36.199 on a Nook that was rooted from B&N software 1.1 using autonooter v3. To avoid this boot loop you should use the latest version of ROM Manager from the Market. Once you have installed ROM Manager from the Market choose "Flash ClockworkMod Recovery" and then choose Nook Color (not old) and REBOOT once the flash is complete. However, since you are here, you most likely installed CWR 188.8.131.52 and now can't boot into your Nook to get to ROM Manager. These are the recovery instructions for that and only that senario. Download this file (CWR 3.0.1 or newer) cwmr_184.108.40.206.zip Power your Nook down by holding the power button until it turns off. Remove your SD card and place it in your PC or card reader. Copy the file you down loaded above in the root directory of your SD card (not in any folder) Instert the SD card into your Nook and hold the power and n buttons at the same time for 5-8 seconds to boot into recovery (CWR). Once you boot into CWR do the following from the menu choices: -wipe cache partition -advanced > -Wipe Dalvik Cache (you may want to use the power button to back out now and then go back in this helps some people avoid the dalvik freeze). If you freeze after this step hold the power button until you power off then reboot into recovery by holding power and n for 5-8 seconds again. -install zip from sdcard -choose zip from sdcard select the CWR 3.0.1 zip file you saved to SD card and then yes. It should run a little program and tell you it is installing the CWR version you downloaded above and placed on your SD card. Once done it should bring you back to the menu. Use the power button to back out to the main menu. Select -reboot system now and you should boot into Nook as usual.
