Title: Simos 8.4 - reversing Post by: dream3R on January 20, 2016, 01:07:57 AM I posted before but no takers to help. I've got it loaded in (I think correct to IDA Pro)
I've manged to find some maps so it looks loaded ok, but am concentrating on ECU boot just now. Any one interested to chip in RSA particularly? Long term goal is a VAG UDS logger but I need to wrap my head around how the ECU works first. Any info appreciated, and good info you will be given a copy of the logger (it's a personal project for me right now). So far two members have helped, thank you. PM me if you like or write here. I've found the EEPROM mirrors (2x) plus defined some boot stuff, but one person it's a total mission with no cross checking, two via a repo easier :) Title: Re: Simos 8.4 - reversing Post by: dream3R on January 22, 2016, 10:16:04 PM Welll I'm getting there, guess I'll post when it's done lol, might be 40 by then... :D

You can only repeat a karmic action once an hour. So that means either 1500 people smote you, or one person waited 1500hrs.

Title: Re: Simos 8.4 - reversing Post by: dream3R on January 23, 2016, 02:00:44 AM well I've found the RSA routine and RAM cell fo my software.
Need a Simos FRF mod to test! and a checksum of datablock corretion. Also from the code the PCR 1.1 does the wrong math I think for 8.1 has anyone tried it?

I quote a hero of mine, never, ever, ever give up. It's got me a 100 % record in everything from a canbus controller to resurrecting a Windows Server when the Dell tech pulled the wrong raid 5 SCSI hot swap not funny. But I fixed it in two hours instead on 8. Taking an educated guess . Once I get the bone I won't let it go and regularly work 37 hours straight lol Title: Re: Simos 8.4 - reversing Post by: dream3R on January 23, 2016, 07:11:37 PM You can only repeat a karmic action once an hour.

That's quite a feat or grudge lol Title: Re: Simos 8.4 - reversing Post by: ktm733 on January 24, 2016, 06:22:39 PM That's quite a feat or grudge lol I don't really understand how except, I did post up cracked software which I felt was helpful but turns out it was't.Title: Re: Simos 8.4 - reversing Post by: dream3R on January 24, 2016, 09:18:05 PM I don't really understand how except, I did post up cracked software which I felt was helpful but turns out it was't. haha, it's only a number man :) Please can we keep OT :P Title: Re: Simos 8.4 - reversing Post by: dream3R on January 25, 2016, 04:36:42 AM Bump any interest to help, code or capital lol, it's been expensive so far.
Title: Re: Simos 8.4 - reversing Post by: sweegie on January 25, 2016, 06:51:14 AM I'm still working on various bits for the Kawasaki ZX10R ECU at the moment, including some KWP toolbox software.... Is there somethig in particular you need? I don't have a lot of time currently, but could perhaps try and assist with the IDA side of things.....

Thanks for the reply, Are you familiar with 32bit tricore or RSA? How much IDA experience do you have? Feel free to pm answers. Title: Re: Simos 8.4 - reversing Post by: dream3R on February 01, 2016, 04:32:32 PM Just an update, this is on hold as I have other priorities.
