How to find pinout for unknown model

Please, follow instruction exactly like described below

In most cases you need to know Gnd, Rx, Tx pins for flash/unlock operations. What do do if you don't have cable or you have new phone model:

1. find Gnd pin (it's required step, you can't continue until you will know Gnd pin location)
2. find Charge pins (it's optional step, just to save your time during future research)
3. find +Battery pins (it's optional step, just to save your time during future research)
4. connect cable Gnd to phone Gnd
5. try to connect cable Rx/Tx wires to all phone contacts one by one (except Gnd, Charge, +Battery pins) and try to read flash from phone
6. if flash read procedure can start this means that pinout found Ok and you can make other operations

Note about "Chinese models": a lot of different phones with the same name exist on market (as well as many different name phones with the same pinouts), so, if you see in our "cable selector" wrong pinout for "Chinese models" it's good idea to find correct pinout according to above instruction and send new pinout information with full text from phone back label to [email protected]
