PRS-T2 Lockscreen Problem after Rooting and Jailbreak

Dear Community,

I did this stupid thing, to tip a pincode to lock the Reader.

And no you can´t unlock the reader.

My question here is, can I use the Users guide in your Wiki for the PRST1 to solve the same Lockscreen Problem for my PRST2??

Iam from Germany.

It would be great, if someone of you could help me with my problem. I just want to make sure, to do the right to fix the problem.

Thanks for your help in advance.

Xaver
