Bootloader update MSS50 & MSS50.1 via OBD

[MpowerE36]

Hi,

I develop a new MSS50.1 program and a Python script to update the bootloader (31801) into a MSS50 bootloader (31800) via OBD. It can be written with Chipster (.bin) or WinKFP (.0pa).

Don’t know yet what I will do with them. The program is finished and released but the script is just a prototype.

PS : an hardware modification has to be done for this to work. YulCmr explains this modification here : https://github.com/YulCmr/MSS54_HP_C.../BDM_mss50.mkd

I am currently working on a public release. It will be available in few weeks. Send me a PM if you are interested.
