Ok so i have already rooted and installed a custom recovery and tried multiple roms but i cant seem to install them correctly, im not a total n00b at flashing i have done it many times before on previous phones, my problem is that when i install a rom sometimes it sticks at the samsung screen, and others it sticks at the SCH-R720 screen the times the roms pass through the boot process i get multiple FCs on system apps and therefore i cant use it so i restore my stock backup, one of the roms that i have gotten to work for a while was the Lunar-gen and i really liked the whole ui of it, does anyone know what could be causing my phone to not take the roms, i follow the steps down to the letter for installations and still cant get it.
