Launch X431 Diagun III Update Failed, how to fix it ?

When update Launch X431 Diagun 3 on the official website, I got error “update failed”, 
error displayed as above:

Diagun III DISPLAY V2.00.002—-Decompression exception, update failed!
Firmware upgrade package V11.15—Decompression exception, update failed!
HM V10.02— Decompression exception, update failed!
For this issues, you need to format the TF card or try an another TF reader card;
if it is the same,  that may cause by the vehicle software downloading was interrupt and the file may be only several KB, then select several car model to update.
if it still the error,  we guess it is the fault with the TF reader.

And we suggest you buy a new SD card reader and install update will be ok. Also your Diagun will work fine.
