HELP bricked vm intercept. wont go in to recovery/ or download mode.

So, i ended up messing around with ubuntdroid.( don't recomend it folks.)
bricked me to pieces.
my phone won't turn on.
at all.
the only way anything happens is if i plug it in via usb,
it shows the charging screen but says that it's 0% charged. ( i know it's not at zero, been charging all day.)

i can get the phone to turn on from there, it loads the black samsung screen with the bar at the bottom, then a strange samsung boot logo appears that i've never seen before. then the screen goes blank.
help.
im dying here.

got it in download mode. but now when i try to revert to stock via sw upgrade my phone just restarts and it wont complete.
