ive been running alliance rom, for quite a while, at least a year without issue, recently though every time i reboot it freezes at the samsung logo. if i factory rest and wipe all data i can use my phone again, and appears to run fine. but as soon as i reboot or shut down it hangs again. tried to reinstall alliance rom but i get an error. im afraid to do anything now in fear of having a phone that doesnt work at all. any ideas?
