Touchpad with Read only iNand
After installing cm-9-20121209-NIGHTLY-tenderloin.zip and camera patch my iNand has decided that he's readonly from now on. (The filesystem is stuck - Format via xp - filesystem returns to previous state on reboot / Delete apps in android, the come back on reboot). Webos secure erase does't erase.
I think I have tried all the fixes previously mentioned at this stage.
These posts describe similar problem: null0pointer post #147 AniWarlock #164 Daiper5 #170
Sending back to HP isn't an option because I live in Ireland & I have 3rd party os installed.
So I am wondering what are the options. From reading other posts it seems RO is caused by a filesystem problem.
Some folks have said the only way to fix is to send back to HP. Since this isn't an option for me I consider what the alternatives are?
Given the iNand is designed to go into RO mode when a filesystem problem occurs (to prevent further damage?), then there is a good chance there must be a way for the iNand get out of RO mode.
Here are some links on the subject

Also interesting, dell streak has similar RO iNand problems
UPDATE: Touchpad eventually died (wouldn't boot at all). Tried debricking with JCSullins method.
It resulted in:
"Image Download Failed. Cookie(if present) not received" = iNand failure.
