Interesting.

Did a clean flash, including erase IDB,
(so my entire workflow for this was: EraseIDB, flash CM10.1 with stock recovery, reboot, flash ClockworkMod on its own, reboot, go into clockworkmod and try to apply fixes)
but still no luck when it comes to the fixes / data wipes.
When i boot into CWM, i cant access the SDCARD the first time... after i tell CWM to reboot recovery, i can.
But when i try, for example, to apply the format_NAND fix, your script tells me, that cache, data and emmc are already unmounted, and so it doesnt format them. And i still get the same error going when i try to wipeData / factory Reset.

Awkward.

Is there anything i am totally overlooking?

EDIT: Trying to manually mount cache and data-partitions inside CWM does result in an error as well.

Alright, i'll do that.

I believe, that is actually what i just did, i always flash the CM10.1 image with the stock recovery first, ever since we started tackling this, but just to be safe, i'll do exactly what you told me to. So, i just copied the (stock) recovery.img into the CM10.1 folder with the Yanando Kernel, then i'll erase IDB and flash that.

After that, i'll flash JUST the ClockworkMod by itself, ticking only "parameter" and "recovery", of course, and i'll then try to flash the fixes using CWM.

Okay.
Installed CM10.1 fine with the Yanando Kernel and the stock recovery image you provided.
So far, its booting fine and the Touchscreen works.

Well, i did already play around a bit with the tablet, respectively your ROM.

Now, as for general feedback for your ROM:
I think its awesome! Its fast and responsive, looks really nice (i saw the designs you preinstalled) and comes with good and useful Apps. I am especially a fan of the USB Host App on there.

So thats great work you did there.

As for the camera:

I am sorry to tell you that it doesn't work...
I tried three different Apps, just to rule incompatibility out as the cause:
Pro Capture says it can't connect to the camera.
Pudding Camera says it can't open the camera (which to me sounds like pretty much the same thing)
and Focal crashes alltogether.

Other hardware, like bluetooth and such, i didnt test yet, but will do.

EDIT: Audio works fine, both playback and voice recognition work nicely, and especially GoogleNow is a sh*tload FASTER than on Stock. I think, for what it's worth, this is really awesome so far. I will keep testing other stuff. And we can still check out the Camera-Issue tomorrow, if you want. I think you already achieved quite a lot here, and you deserve a break and some sparetime. We can still check out other stuff later. And just so you know: i am really very grateful for all youve done so far.

Alright, second check of the SDCARD turned out fine as well, no errors.

Also, youve got private message.
