Galaxy S5 SM-G900p
I've bought a galaxy S5 and i want to unlock it . I tried several thing none of them worked. It has G900PVPU3BOG1 firmware with 5.0 lolipop (I cannot downgrade it tried a bunch of firmware it only flashes stock 5.0 everything else sw rev check fail) so SSU.apk not working .I have tried Octopus, (Unlock switch stays grey), Z3X It says unlocking ....done .
But if i want to put in a T-mobile sim card it says invalid sim card . If anybody have an idea or solution pls let me no, I'm almost gave up .
