Foxflash reads Renault EDC17C42 ECU ok, but failed to write. It is write protected, error “OTP sector not writable”， what else can I do?
Bad modified file, you are changing OTP section. People have done EDC17C42 OBD and Bench working all ok.
Not protected. Your file is bad. Change your tunner supply!!! Bad Solution.
Bad file try to write original file and see if all is ok you have bad file.
Do checksum manually.
