Yeah, I left a few scratches and things don't look particularly clean after that exercise. In order to avoid having bad news to report, I refrained from actually powering up the device after the cap extraction :) http://people.openmoko.org/werner/1024-done.jpg > Which Dremel tool did you use, the "disc/die" or the round Korund > (usually pink) thing?

I think I used one with 0.8 mm diameter (shown in the picture), but maybe it was a 0.5 mm. http://people.openmoko.org/werner/1024-tools.jpg > Probably the glue was left from production models of the GTA02 or even > GTA01-V4? I don't really know. Perhaps it's a good idea to avoid any attempts to unsolder the cap in GTA01 in general. - Werner _______________________________________________ hardware mailing list hardware@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/hardware
