Modifying panasonic flash

[meff]

Is the flash file protected with crc like in nokia? Any ideas? I'm working on a language file...

After some tests i can tell you what i know:
- flash file is protected by crc's (just like in nokia)
- as far as i know there is no crc calculator available
- when you flash corupted file to your phone the phone is dead and al you can do is to reprogram flash chip with an external programer
