If you’re rocking a Nook Touch eReader and aren’t shy of hacking it android ways, here’s some very sweet news for you — your eReader just got a ClockWorkMod based recovery, and although it’s in beta 1, most of the useful stuff works: backup, restore, mount/unmount USB and install zip from sdcard (as confirmed by the developer mali100 himself).
But it’s not a cushy job to do, you need pretty knowledgeable with all this hacking stuff to be able to install ClockWorkMod recovery. Mainly, you’ll need to write the given recovery image file to a 2Gb sd card and once done, simply place it in your nook Touch and reboot. For your help, developer has provided whole lots of instructions (and download links), which you can get on the official development page here.
