Just like the title says. I am unable to flash anything to the stock slot on SS. I have tried ,any different times. I have tried wiping the slot and then flashing a fresh version of the ROM I use and also wiping and restoring a previous backup. Everytime when I go to boot the phone it gets stuck on a black screen during boot up. I end up having to use Matts tool and reinstall things back to stock including having to reroot. Anyways I would love to use my stock slot. Any help would be great. thank you
