I'll share here all the pictures and the method, that can help you easily connect your China phone and more than that, Samsung, Sie, OKWap, LG, Innostream...can connect to PC, to flash, Unlock, Read, Write, Format(China Phone option only)

Prepare:

-01 RJ-45 port, that you can buy at Computer service or from a discard LAN Card or Net switch, or box, PC mainboard...
Doing:
For easy to explain, I'll use PL-2303. And to take all advantage of UFS cable kit, we make all kind of phone self-made Cables following UFS standard, so that, we can use UFS cable with this Virsual COM, like C19x Moto, 2xx Sie, 4xx Sie...
Solder RX, TX, GND as this Picture:

All done of the main part!
For the other part(Connect to phone part), you can use Connector from USB cable of the phone, Die Charger to modify them, that fix the pinout, for example:
