Yeah I tried doing this a few more times. It won't work with these batteries. I even tried updating to 3.90 M33-3 and booting, without the magic memstick. :/.
The memorystick I have is a Sandisk Memory Duo Ultra II 4GB, if that matters.
Very well, cheers.
Ok, then the problem is that Hellcat's application is not changing your battery serial for some reason. Could be due to a bad EEPROM chip.
Just wondering is it a Sony branded battery?
