didnt you save your origional radio?

or just try again??

it worked for me first try. what did you do??

You should have overwritten the first 444bytes of your 1.13 ROM with 444bytes a SD card backup of an older Radio ROM!

thanks your adivse let try again

[gradius44]

416 bytes would be ok, I have done and works fine.

[rjtd]

What software do you use to replace the bytes?

[gradius44]

Hex Editor, you could find it at the ftp server of xda-developers.

Be very carefull with that. This is NOT a full ROM backup, so the layout is different. I would strongly suggest copying all the bytes, or you could end up with that dreaded paperweight.

what if you don't do the 444 bytes things ?

can you just copy the radio as is ?

thanks

[HBK]

I have no clue, and I would never try to do it. Far too big a risk to take, just to save 1-2 minutes...

[bruxelles5]

i say this because I don't understand this part (overwriting the 440 Bytes from 1.13 Radio with the 440 bytes of my older radio 1.12 )

is that this way or vice versa ?

When you open an hex editor ? What do you see ? how can you see this is the first 440 bytes ?

thanks man if you can help me

Those first few bytes, in this case 444 of them, contain an unique device ID. That ID is needed to 'authenticate' the ROM-image when being flashed to the device. I've tryed to flash my Magician without patching my new ROM with a number of bytes from the older (backup) ROM. The device gives my some freaky error, but nothing else happens, since the bootloader detects a 'bad' ROM.
