People may had software flashback problem when install Tech2Win 2TB HDD on 64 bit system (Win7 /Win10 64bit). VXDIAGSHOP engineer has tested and modified the HDD/SSD on 64-bit system.
No flashback issue.
Don’t need to run t2w from Porsche software anymore.
Directly run Tech2Win from GM software.
Choose device as MDI2 but not VXDIAG.
