5120i nsc-1 v4.03 MCU+PPM

[stas]

Hi again ppl... I have a 5120i NSC-1 mobile with sw v4.03. I built myself a dejan cable, dumped it, and here goes the result ;)
Now, I'm really curious... Can a "big shit" happen if I reflash my mobile with more recent 5130 NSK-1 firmware? I was seeking on Google and found several guys reporting that such version mess works fine... But they don't say if they mess with NSC/NSK thingie... What is that for? Just a sub-version?

5120i (NSC) is TDMA, 5130 (NSK) is GSM. If you flash the 5120i with the firmware from the 5130 it will result in the 5120i becomming a brick, the two standards are incompatible.

Ya right dude... This page says (almost) all "systems":

But can I use firmware from 5125 (NSC-1) on my 5120i (NSC-1)? or 6120 (NSC-3)?

Although I don't know for sure what the differences in hardware (if any) between the 5125 and 5120i. I really don't think much since they share the same service manual. I think that you may be able to get the 5125 firmware to work when flashed to the 5120i. As for the 6120 that is doubtful.
