Phone doesnt Boot up. Black Screen

[jose14906]

I have this Epic 4G . All of a sudden it started doing this.
I turn it on and it boots up to the samsung logo and then the screen turns black but then the bottom buttons light up. It stays like that for about 5 minutes and then reboots by its self and does the same thing.

I dont know what the problem is, and have no idea what to do :'(

Please Help.

Sounds like the rom became corrupted. It's a pretty easy fix using ODIN. The directions are a sticky, and I'm sure PaulG will chime in with the exact link, and which procedure to use. You likely will lose everything you had on your phone, but the process won't touch your SD card, so pictures, music, and such will still be there. Your contact list should also be synced with your google account. If restoring with ODIN doesn't fix it, than a trip to Sprint is in order, as it'll be a hardware problem then.

Here is the link for Odin and the factory restore that ratsttam spoke of.

[How to] Factory Restore (or Fix a Bricked Phone)

Use procedure #1 for Froyo EC05 and then from there you can update to Gingerbread.

Thanks, but I cant get into download mode to do this. For some reason, I get into recovery mode, the computer does detect the device as an unknown device, but windows disables it because it "malfunctioned" .

When in the system recovery, at the bottom it says.

E: Can't Mount /dev/block/stI10
(Invalid Argument)
#Manual Mode#

You want it in download mode, not recovery. Download is holding the "1" key then press power. You may need to use different cables/ports before the computer will recognize it. Samsung is pretty bad about drivers and just working in windows :-/

I have been in the similar situation before. You need to use differnt usb cables and probably different usb ports. Also try downloading the drivers and installing them before you connect your phone to the pc.

It basically becomes trial and error at this point until your pc/odin recognizes it.

I just reflashed my rom using clockwork recovery. no need to wipe my phone.

The OP didn't indicate that they were rooted (and therefore likely didn't have CWM installed). If the ROM was corrupted, a "factory" reset with the OEM recovery won't help that.
