Just a little tip I'd like to run by OP's approval, since he is the expert. When it asks for decryption by PIN and you've been using a pattern, I was able to "translate" pattern to pin using the following matrix:
1 2 3
4 5 6
7 8 9
So a diagonal line from bottom left to top right would translate to a pin "753" unless 5 is already used by another line in which case you'd go directly from 7 to 3. Hope someone finds this useful!
thank you very much, in my case I solve it formatting data, not wipe data
