USB no longer working... Does the old flash dance still work?

[Slartibartfast]

When I plug it in to a computer it charges, but that is it. I have tried 3 different cables and 4 computers.

Right before this happened I started having weirdness with the phone thinking headphones were plugged into it.

I will be able to purchase a new phone Oct 1(supposedly, sero), so I just want to keep this one doing the needful until then.

I flashed back to stock to rule out any weirdness caused by roms, didnt help. I have realized I really do not like stock though and want to go back to Energy.

Will doing the old flash dance(no task29) and flashing from SD card cause problems?

Thanks.
