Need some Help: I am on Build VS98012B, rooted and TWRP 2.6.3.3 installed via FreeGee. I was able to created a backup of the rooted stock rom, but when I flash a custom rom and reboot, the LG logo pops up for a split second and then the screen goes black. I am able to get back into TWRP and restore my backup to get back to stock rooted. Any suggestion on what I need to do to get a custom rom installed would be appreciated. Thanks
