Not my first bootloader, this is even able to read and write external EEPROM of the CPU, but i think most people want a config changer here and i hope to get it work this easter days... Who just needs a dice flash reading tool can pm me to read out his complete CEM flash when he got code by teensy b...

Yes, I cut the trace between V-USB and V-IN. You have a Red wire running from the Teensy V-IN to J1 V-USB. That is the same as not cutting the trace. You also have Teensy grounded to the USB port. Remove the Red and Black wires fron J1. Plug the interface into the OBD2 port. The Tennsy will power o...

I have IO Terminal and can read flash .bin, but I need a PIN first. And if I have a flash read on the bench (for example) I can extract PIN from it. As VTL said there is something really off. Download the latest Teensy code and run it as is. Double check all the connections on your Teensy. Post som...

Remembered i had this software if anyone want to take a look at it.

Third byte (shuffled) should be 65, and it was indistinguishable in the very first pass and got filtered out. You can email me your dump, I may find time to load it into my CEM and try with my cracker, which seems to work fine in cases when others fail.

Hello to all! I tried to crack CEM from the 2012 Volvo XC90, but I cannot for some reason. Tried with OBD and on the bench. Same result. Also, I tried different shuffles, but without success. So here are the logs if you find a problem, please fix it. Here's your pin compare routine disassembled. Ba...

This commercial tools are based on work from this open forum. Isn't it strange all tools came on marked shortly after this project was visible here. Now you blame us that we don't develop so fast like the guys which get 4600 $ about their full set. I think VTL and I did this just for our own cars, w...

Do you mean via an open source obdii reader where the k-line source code is freely available? No ... You can build a cracker with a K-Line but it is only useful with the CEM-B through the OBDII connector. If you tap the CEM-B CAN on a port other the the OBDII port you do not need K-line. It not wor...
