does sound like a battery though...

that red led light comes on when a charger is connected and the power on the phone is too low to turn on yet. Has happened a few times to me...like when my phone completely dies at work then when I get home I plug it in(red led comes on) then after about 1-2 minutes of charging I can turn it on.

Since you tried your friends battery and it does the same thing...Double check your battery connections on the phone itself. Make sure they are still spring loaded and not bent..Also clean them with some rubbing alcohol and a q-tip.

Though it would be really weird for this to happen at the same time but Ive seen weirder stuff working on cars...
