Download Mode and bootloader
Hi guys! I've been having problems with my Mega. My phone works really fine. I just got it the other day. But whenever I try to go to download mode or recovery I only get a blank screen but I know that it goes to download or recovery because my phone could detect it. I've been reading some forums that I have to reflash the bootloader of my phone so I could fix that error. Does anyone here confirm this and could anyone provide me a flashabble copy of the bootloader? Thanks!
Here's what I found on the other forums:

Power off the phone, hold down VolUp + VolDown + Power for 4 to 5 seconds. Then release ALL AT THE SAME TIME. Now press Volume Up. Now hopefully you will be in download mode even if you can't see that you are. If it doesn't work try it again a couple of times. The reason that you have to press Volume Up is that a warning screen is actually displayed before the phone lets you into download mode.
The phone will give you no other indication that its in download mode and won't 'recognise Odin' when not in download mode. Make sure you have Samsung USB drivers (comes with Samsung Kies) installed on your PC.
Oh yeah and by the way the thread I've linked to suggests you have to reflash the bootloader to fix the 'blank screen' problem.
Mods, could you delete this thread? i've move it to the android development forum. Thanks! Sorry for the inconvenience
