stuck in bootloader.. sd rom upgrade freezes on loading... screen

[bad-s]

k i am a noob to this still but thought i had a better idea of what i was doing. i have just started playing with rom upgrades lately but now i have a problem.
im stuck in bootloader, the screen reads

TITA100
SPL-2.07.0000
CPLD-9

i have tried flashing roms through the pc with no luck, wont go past 0%. i have tried the SD method and everytime it just says loading... but wont go any further. please tell me i didnt **** this phone up! i have read through a ton of stuck bootloader threads but dont think that i have found my answer! what do i do?! id prefer to have everything back to stock with a 6.1 rom!
