Aren't there any alternate points for data1 and data2?
That's my problem, too. Filesystem errors on root, some apps don't work anymore, can't open the contact list. I have to reflash!

There are debug ports, also for USB. But I couldn't get a working connection with them, yet. I tried with Data+, Data- and GND.
I'm not assured this is really USB. Maybe I'll have a look at the schematics/PCB

edit: I've found J5300 and J5301 in the schematic and the PCB, these are described as USB D+ and D- in the schematic.

Seems like another way for a USB connection, without soldering on components again
