5 bytes/10 nibbles on P3, in HEX.

UDS just needs a correct seed/key pair, and will give 65,536 pins. Any will work. Algo, and python script should be here in the thread, or over on the other site.

Curious, why 45536? Or is it BCD pins? For HEX it gives 65536 collisions.

It's 65536. The 4 was a typo.

Just a DICE-206751 is enough to crack pin and dump full flash without any risk.

(or 2005- CEM with series number starting by 0000491...)

@t5luke I have a MY2006 s60 will verify the serial/series. Are you able to write to cem as well? Can you share software? Thanks

C'mon, opensource it!

I'm so lazy that I'll never write a CEM flasher for my needs, even that I know most of everything that is needed for the task (90% of which is thanks to you).

I won't make any secret about it, the code is here in forum already. Take the standard routine and bruteforce with this. You can log the commands or i can write the p2 commands here no prob. When i get my code clean and checked every dependency i would do this. But don't forget we have different rights here and so on, also our country is one with the biggest car industry. Rights are more friendly to industry here. A company like the one in Czech couldn't exist here... I already heard about people in Sweden got threatened from cz just by logging soft...

Maybe i find the free time to do it here as open...

I can also post bootloader to dump cem, maybe it has use for teensy project...
