Clone Carprog PCB Rework (customer solution)
This help fix the cloned Carprog to get it to work (e.g. read security codes or read flash) as the original.
The bad Carprog clone:
many members with Carprog clone can say it will work have to tweak it ,and read the manuals really only for mcu usage. I have retooled and remade many of my own adapters , also changed bridges , caps , oclis crystal etc on mainboard also flashed to 4.74 firm . all the N/a are gone and eprom and mcu reading is great no faults. also fixed ground plane and insulated board from aluminum case with k tape. its working fine now but has a nice coat of dust on it.
Here is what you can try to rework Carprog PCB:
Check A1. You may need to improve the work can.
First and most important of all is to change 74HC125D to 74HCT125M on your carparog, i have good clone (good pcb) but still did not read some I2C,95 ,MCU. I bought 74HCT125M at farnell change all 4 of them and it is ok now. reading without problems.
If it’s difficult for you or you fail to rework, perhaps you could buy a HQ Carprog programmer at the best price (Forget the cheapest!!! you will get what you pay for, especially for China clones)
Good luck! Try on your own risk!!!!!
