Ok, back in the office. Here's my collection of CzOne Rock carcasses.
- There is no SIM card, microSD, or other memory card or socket.
- I could not find the matching USB cable, so I could not check if the internal memory is readable via USB.
- The two contacts on the side are the connection for the desktop charger. I have idea how they work. On the one phone that mostly works, it shows 0 volts, which is probably due to an internal charge controller or isolating diode. I could not find a drop in charger to test how it works. I think this might be the best solution if you decide to keep using the phone.
- I went through my collection of tri-thing drivers and found a few that would sorta fit, but are too loose in the screw head to be usable. The drivers I have on order have not arrived yet.
- I would gladly sell or give you one of these phones as a spare, but none of them totally work. Maybe I can supply one after the tri-thing driver arrives, or maybe take your chances on eBay.
Sorry.
