i purchased sx os pro when they just released been using good from that. i never turn on any autoRCM just booting by pressing power + volumn up. couple days ago i tried to boot the same way i used to do. after the sxos logo the screen was black. i tried to format my sd card nothing changed. i tried to got in to the booting menu and i found it said that "no payload" found on my sd. i believe my dongle is broken. any idea how to fix it guys
