My Galaxy s3 d2vzw will not turn on custom rom slimkat 4.4.4. So about 3 days ago i decided to put a custom rom onto my gs3 and i have learned alot but i just ran into a problem when i tried to flash a new modem to slimkat 4.4.4. The image caused my phone to not turn on anymore and i was hoping someone could please help me get my phone to turn on. Its kind of weird because when i plug my phone into my computer, my computer beeps and acts like it recognizes my phone. And when i press the power button for about 40 to 60 seconds while it is pluged into my computer it beeps like it just got something disconnected but when i let go of the button the computer beeps like something just got plugged into it. pleeeeeeaaasse if anyone can help please do its my only phone and i was getting tired of the crappy touch wiz.
