KTAG V7.020, KESS V2 V5.07 Wake up error four reasons:
1.Must look at our video installation software, because some systems need to patch, if you use the software directly, you will wake up error.
2.The Chip is not well soldered – solution:try to solder the chip once more
3.tf card contact is not good
4.The model is not supported, you need to try another version.
