After my inital troubles with the Pandora battery, I have not did it twice and am happy to report sucesses!
However, the third time I did it, I decided to back-up my 3.52 M33-3 NAND with the hope of restoring it after the downgrade! Just wanted to try it!
However, when copying my NAND I got the following 2 lines
Is this normal? It still created a NAND file in the root of my memory stick, but when trying to restore it (hey I have an unbricker - thought I would risk it!) it says cannot open file?bad block at page 17632 block 551
