So installed doomkernel yesterday along with a custom rom, now the rom causes a bootloop(LeOpArDx RoM V5.0 Small Package.zip). I tried installing zip from sideload for another rom but the device doesnt show up in the cmd when writing adb devices. I installed usb drivers with sdk but it still doenst work. Please help I just want to put another rom onto the device but I can't transfer it. Also the device wont go into flashmode only fastboot.
