I have messed up my nexus 7 and now can't seem to recover it or don't know enough to recover it on my own even though I have tried many suggestions on the web.
my 7 was rooted, then I installed multiROM TWRP v2.81 because I wanted to experiment with different ROMS. Somehow when I got the OTA update notification I tried to install it but every time the system rebooted it went into TWRP menu and didn't let me update to lollipop so in the TWRP, I must have have deleted the kitkat because now I can't boot the device up at all. I can only go into reovery mode which gives me the multirom twrp menu but from here I can't seem to be able to do anything else.
Am I screwed or do I not know enough to get myself out of trouble? I have attached some pictures if that will help.
Please HELP ME!!!!!
Tks in advanced...
