MB Star C4 is the upgraded version of C3

Also you can change serial number of your device. 24c02 contains it. After changing number just run “factory settings” function…other way it will not change. After reboot you’ll probably see (on lcd of your device) your SN looks like “the number you’ve programmed into chip +1″… I mean 10001 inspite of 10000 for example and so on, but in SDNC tool kit you’ll see the real SN (10000), and after succesfull reconfiguring your device you’ll see the right number on LCD of your MB STAR C4. I was using cheap ssop28 (0.65mm step) adapter and Pickit3 programmer to read/write PIC16lf88. This scheme made for Pickit3 OEM socket(ICSP).Also I’ve got dumps of both flashes 29f016 and PIC18lf8680 if somebody need it.

It did not take me long to find an affordable MB Star C4 diagnostic system. I bought mine from China www.mbstarshop.com as a complete package including the Del laptop with the software installed. I chose that company mostly because diagnostic systems seems to be their business and they were quick to respond to any questions I had via email. I opted for the laptop rather than just a hard disk as I really do not want anything from China on any of my other computers or networks (which is where I earn the money to pay for these hobbies). Buying the laptop from them was no more expensive than getting the hard disk and buying a lap top from ebay. I think the complete system and laptop delivered via DHL Express in 3 days was just at $700. The software is very elaborate and it probably would have helped to understand German.

MB Star C4 is the upgraded version of C3, it does all works MB STAR C3 does, but has some other improvements at the same time. By using the benz c4, wireless diagnosis, K diagnosis, L diagnosis, CAN BUS diagnosis, UDS diagnostic protocol, wired connection are all supported. C4 is hard to influence by the environment, smaller and lighter.

I know it exactly because I’ve succesfully unlocked 3 units for last 2 days using it. Each one works fine.You don’t need to buy a new one PIC16FL88. You just have to program chip from your own device.After that when you run your SDconnect you will probably see that serial number, OS version of your device are changed into zeroes “0000″.Don’t worry. Just change your C4 to factory state using buttons near by LCD (no need to explain “How to…” because it’s quite clear). After rebooting you’ll see actual SN, OS version and so on.
