Something went horribly wrong! First I wiped everything excluding internal storage. Then I flashed CM11 and SFOS. I tried to boot but got black screen for about 10min. Then I rebooted to safestrap and selected ROM slot 1 instead of stock ROM. Then I tried flashing again and got black screen for 10min. After that I was not able to boot safestrap again. I was able to boot AP Fastboot so I tried to flash FXZ. After 5min FXZ failed because I was out power. My Droid 4 doesn't charge anymore. I guess that I need new Droid 4 with fresh battery so that I'm able to recover my old Droid 4. I don't know what I did wrong
