Working on CO_VP2

so here I'm lost... I can not access to a working unit. Any place where I can find it?

What programmer do you have

For this part I will use the TL866II Plus. It is like the famous T56 little brother.

Yes, if you are lucky you can simply reprogram the original NAND chip with fresh firmware file and then reflash the unit via USB once working but the NAND chips suffer from bad blocks and if the firmware image rests in a bad area then quite often the unit will freeze before loading. Just so you know even BRAND NEW Nand memory can have bad blocks. Reflashing via USB with a working unit will study the bad block table and write firmware to suit most of the time but you need a working radio first. I have not seen enough radios to excite me to looking further at the option of hacking the official bootloader and reprogramming the Nand onboard with bad block detection.

No luck only reprogram NAND you need to be change ID's for working unit example your unit boots but no sound, not same x,y,z touch screen etc... you need to match ID's serial if you have original S/N and ID's on your nand...

Also for can messages you need play just VIN from b-can on bench
