Spark Posted June 16, 2017 Share Posted June 16, 2017 hey riders, to speed up my efforts I thought I just ask for partners in crime is the firmware binary crypted? looking at it in the hex editor right now I'm not sure ;=) can s1 give me some info about the processor used on KingSong KS16B/C models and the flash rom used? (I dont want to disassemble my wheel yet, as I use it every day ) I plan to use IDA PRO to analyse the firmware. the V.125 binary is 49.280 Bytes, so I wonder where is the rest , read the part of the rom where the crap media files are stored (HELLO KINGSONG! ) there are two things I want to achieve: 1st disable startup message, bluetooth on off message and please deaccelerate forever. This could easily be done by erasing those files from where they are stored. 2nd speed up my KS16b 820Wh to 35 km/h This could be done by either directly modifying the engine parameters in the firmware or maybe even by tuning the android app that sets the max speed parameter. (has anyone tried this yet?) If you have read out the flash that stores the media files, that would be helpful too. Im also looking for all KS16B/C binary files in all versions, in order to compare code changes. also any info on checksum calculation are welcome, (if crc is just handled by the android app, I wouldnt waste any time on this) cya Link to comment Share on other sites More sharing options...
