Which boot screen are you trying to move past? Recovery? Bootloader? How did you root? Which ROM? The more info you provide the better we can help. Thanks and welcome to the forum.
Hey having the same problem. I can load to the recovery but it won't boot past the motorola symbol. But when it actually does boot past, i can load on to the lockscreen but my touchscreen won't work. I've been on the CM Nightlys, new GBA13 by Peter. Any clue?
