HELP!! Rainbow screen!! will only boot with usb plugged in.. anyone heard of this??!

My phone is Alltel.. was working fine.... then out of the blue it went to rainbow screen... now everytime i soft reset it goes straight to the rainbow screen and ways "serial" and will not boot...!! However,,, this is where it gets strange.. if i plug the usb cable in for a split second it will soft reset and boot fine! and work fine!! CRAZY.. it does not have to be active synced or anything.. just if it is pluggrd in even for a split second it boots... once it starts booting i can remove the usb cord and its fine... but i cant soft reset without it being plugged in.,. HELP

PLEASE

Have you put any custom roms on lately? Maybe you should try to use a different unlocker. Just a thought. I had problems with my phone randomly rebooting, and this seemed to do the trick. I know it isn't the same problem, but it might work. Maybe someone with a little more knowledge will chime in.

Others have said this is a hardware problem with no fix. You can try a hardreset or rom flash, but.....

This worked for me (I have a HTC Mogul 6800 and I too was on bootloader (rainbow screen) this is copied from one of imcokeman posts.

Hope it works:
Stuck in TITAN bootloader? Read this!
The Titan is different than most other PPCs in many ways, but one is the key to exiting the bootloader. Most devices you connect to it with mtty and run the command "set 14 0" then reset (task 8 works). On the Titan/Mogul/6800 the command is "set 16 0".

Now the good news for those who don't want to go the mtty route. I have modified the uni_exitbootloader program with this change so that it will work on the titan.

Usage:
Connect phone to USB port, disable activesync and run the exe. If you need more info search for the other stuck in bootloader threads. There are already many tutorials out there for this process, but this is the only tool with the special Titan exit code.

get it here:
