Minimaxx Reboots When Pressing Install Download?

[Powerstroke Man 6.4]

So I got a buddy with a minimaxx wanting to get some GH tunes on it.

(tuner is already installed on the truck W/ canned tuning)

went to try to pull the base file, and get the base mcc file exported.

Press install download and the minimaxx reboots back to the main menu.

Tried it a few times and same thing happens, check the OBDII block and HDMI same.

So I grabbed a spare HDMI wire I had and same problem.

what could be causing this, could it be the OBDII block?, when you flip the switch to key on power it will not turn off and has to be unplugged even with the key off.

I wanted to wipe the SD card and update it but I didn't want to risk bricking the truck and leaving it stranded.

Thanks

copy all of the files off the card to a folder. never ****** the files!

format the card

paste the files back to the card

usually when the unit resets upon a button press, it's a card issue. USUALLY

updating a tuner will never brick a truck or leave it stranded
