Step 1: Gather necessary equipment...
1 Earpiece adapter for vx8500 (comes with the phone)
2 USB cable to mutilate
3 MicroSD card *optional*
5 Drivers (not necessary for linux, as for windows, you're on yor own.
i would try the drivers from my other phone tutorial first, they should work)
Step 2: Prep the Adapter (and start using bluetooth headsets)
Step 3: Remove the hot glue and jack
Step 4: Solder up the wires.
use these pinouts:
1 GND (black wire)
4 VCC (red wire)
12 Data + (green wire)
13 Data - (white wire)
solder the pins as indicated, please note, when i first built this i had the D+ and D- pins confused, so they may be backwards.
When you're done charring your fingertips and expanding your young neighbor's vulgar vocabulary, test the cable. using an EXTERNALLY POWERED usb hub, plug the cable in to your phone, ip the charge icon appears, you wired the power pins correctly. now plug the hub into your computer. (in windows) A window should appear telling you to install drivers. if it says something along the lines of "usb device malfunctioning/ not recognized" switch the d+/d- pins and try again. In linux, just open bitpim, if it recognized the phone, great, otherwise, try switching the pins, but first make sure bitpim is allowed to access the usb ports! (it only works for me if i run it as root)
