I had been playing around with CM10 on my recently acquired PendoPad 4, and to my surprise, it works....to a point. Unfortunately, my skills are not that great yet, as I am new to Android as well. I simply followed the instructions at [rom] Unofficial CyanogenMod 10 for many AllWinner A10 tablets - xda-developers
and installed the ICOO D90W and clones compatibility (version 1.2.1).
What doesn't work appears to be networking. Wifi won't connect at all, and neither will the 3G dongle that comes with the unit. I am sure if someone else who owns a Pendo Pad that is a little more resourceful than I am at the moment (moving interstate shortly) they may be able to crack the last piece of the puzzle.
Lucky these units are hard to brick, as I tried a few other "Compatibility" files, to no luck, including not having a touchscreen in one. Researching online, the Pendo Pad is closest to ICOO in design, it would not surprise me if they come out of the same factory. Just some small tweak will probably make a buttery smooth CM10 Jelly Bean work nicely.
