OK Guys, I'm in big trouble right now. I wanted to install a Kernel. I was on Viperrom 2.1.0. Something went wrong and my phone went into a bootloop. After trying a couple of things(like installing another Kernel) Everything went from bad to worst. Now my whole Internal Memory is erased and there's still a bootloop. Luckily I can access my TWRP Recovery, but i can't mount my sdcard, because it says thats it's unable to mount sdcard. How can I transfer a rom to my sdcard so I can install it?
