XPROG-m v5.70 failed

[rosak]

Hi,
bought Xprog-m v5.70 china clone a few months ago, that's version with USB dongle. Worked fine for some time and I was very happy with it. I mainly use it to read FLASH and EEPROM from MCUs MC912DG128A and H256 etc. It used to read both FLASH and EEPROM. Now it still reads without errors but every dump differs a lot, every few bytes I have differences. Is this some common fault? Anyone knows how to fix it? I can buy another one but maybe it's something simple to fix.
Thanks for any help.

These chinese X-Progs are a crap. Mine didn't work at all. 80% of times "Device is silent" error is displayed. Sometimes it reads eeproms, but dumps are different. Tried to resolder. No luck.
Some people advise to use an external power source. I will try it also.
