So recently I got safestrap after being impatient to wait for a bootloader for a tripped 4.3 d2vzw (which I doubt will ever come out). I followed the safestrap directs carefully. I installed the latest 3.71 apk, installed the recovery, and booted to it. Whenever I try to flash any roms though (in a seperate slot of course) it says successful but when I boot nothing happens, it is just black. I can't turn it off or "on" during this unless i pull the battery. I've tried many roms including, CM10, CM11, Paranoid android, synergy, and cleanrom. The only one that stood out was synergy, it had an installer pop up but after it "installed" and i rebooted it did the black screen thing again. I've tried wiping each rom slot every time messing with different options everything. I even flashed the kernal thingy after each one. It just refuses to work. Anybody have any ideas? It would greatly help. I just want my phone with no samsung bloatware and preferably CM11. Thanks
