do a full format of the data partition (see Thor's guide)

I suppose you speak about this : How to REALLY format data partition if it gets corrupted
: viewtopic.php?f=8&t=83

But this is based on CMW.

And I don't hace CMW. I had TWRP.

So what can i do?

thks

why don't you download a cwm recovery or thors 1.7.3 touch http://forum.tegraowners.com/viewtopic.php?p=13740#p13740 recovery and flash it then do the real format in the new recovery?

I'm facing the same problem, anyone who just help us, thanks.

HI VeraKeisey,

Maybe we can try to identify the cause of our problem.

Which rom/recovery/bootlader have you installed?
Have you an A500 or A501?
Have you done something special?

I have the same problem. Did you get it solved ?

Even when I try to do a "badsector" format it stops at the first block. First thought was that the flash was bad(could still be). But since I cant delete anything on it or do a factory reset. My guess would be that the flash have become writeprotected ? (Bad line, chip lifting ??)

Sorry no i haven't found any solution

I think that some sectors are dead but don't success to bypass them

You can see here all mu different try.....without success
