[Q] Trying to flash new rom, phone won't boot
My GS3 was running The People's Rom 3.16 with KT747 kernel, now I'm trying to flash to Vanir rom 4.3.1. I did all my backups, but was having problems with my external sd and had to format the sd... then redid my backups, cleared cache and dalvik, factory wipe/reset, then went to install Vanir. Vanir wouldn't complete install, it kept aborting a short ways into the process.
Now my phone won't boot at all, despite many more attempts at wipe/reset. I had this problem when I first flashed TPR 3.16 that it would get to the Ktoonsez KT747 screen and get stuck and reboot, but clearing the cache fixed it. Now when it gets to that screen, it just reboots into recovery. Please please please tell me I didn't just brick my phone...
EDIT: I tried a new micro SD card, formatted it FAT32, and got the rom working.
