TP2 Flashing problems, stuck at bootloader.

[krazyjack]

Ok, I admit I am completely lost.
My phone began having some connection issues and I started blaming it on the rom I was using. So I flashed to a new rom without incident but didn't like it so had to flash again. I have actually done a few (all Energy roms since June 6th and up) but began having more problems with the connection.
The connection between the computer and phone began to cut out more and more to the point that I began not being able to complete a flash.
Then I came across the 'task 29' method and thought that was probably a good idea, seeing as how my problems could be attributed to old junk piling up.
The format completed and the software began to load onto my phone but stuck at around 20% and that was that. The phone now comes on every few minutes in boot loader mode (but only when connected to some sort of power source) then goes blank.
Windows keeps saying its an unrecognizable usb device and therefore i cannot connect that way.
I've tried flashing from the sd card. Bootloader comes up and immediately goes to the 'loading' screen but does not load and goes back to the bootloader screen, but only for about 10 seconds and goes off again.
So to recap:
mtty isn't working because the phone isn't being recognized by the comp.
flashing from sd card using the methods posted on here not working.

So if anyone has an idea, that would be GREATLY appreciated!
However, as a last resort maybe someone could tell me what should be on that bootloader screen so I'll have an idea whether or not I can go into sprint for their help.
Only thing I can really make out on the screen is (spl-1.00.01inex).

TIA!
