A few months ago I bought a CARPROG FULL V4.01 on Ebay. It cost me US$250. I just need a universal tool which can do car radios, odometers, dashboards, immobilizers repair. I also heard that it also can do EEPROM and micro controller programmer, key transponder programmer. Well, it fit me.
One day, I found that a colleague had a same CARPROG FULL V4.01. But he said he only spent $150. He told me that he bought directly from a Chinese Xcardiag website.
Well, Depressed as I am, I do have my own harvest. From now on, I can save lots of money on my diagnostic tools.
I am here to share my story, you may refer to it. BTW, I am not affiliated with this company, just a customer.

 

The tool is updated to Carprog v5.31 now. You can try to update it to solve the problem.
