Do not run Samsung tools with the desktop shortcut. It shows error "card not found". Read the following
RUN "Z3X 24.3 Loader.exe"
AN "INFORMATION" BOX WILL APPEARE. HIT "OK"
RUN "Copie de gsm-magic.exe" AND CLICK ON "ENABLE"
Then, CLICK ON "START LOADER", NOW THE SAMSUNG TOOL PRO WILL START.
Repeat above process every time you run Samsung tools pro. The error will gone.
*edit* so it doesnt work on 6.0.1 modem you need to downgrade to 5.1.1 modem unlock then flash back 6.0.1 modem then it works.
