so.... Yea.... This might actually be the cause (or related) to my problem.
I can't get into download mode. This seems like a legit hardware issue... As opposed to me being the issue. I tried all the variations I could think of (volume down+power, volume down+home+power, volume up+power, volume up+home+power...).
I even watched a video of what to do, and what the phone SHOULD do (on a side note, that android with the shovel is pretty clever).
If that's the case I'll return my phone and get a replacement... Maybe I'll have more support with the THAT one
Please look at this
I am happy you fixed the problem.
But as Casz said I have never seen that, the only way I think that is possible is if the cable was damaged or Proprietary designed specifically for another device, so it would charge but not connect (Which is doubtful).
P.S. What about your brother's phone?
