Member: 148515 Status: Offline Thanks Meter: 19,534 | hello! 1. how did you get know that this is mt6225 inside? 2. please count number of pins in system connector. Is it really 12 pin ? 3. does this phone is able to be powered On from pinfinder power? (this is important rule to get pinout found) |

Member: 870970 Status: Offline Thanks Meter: 1 | 1.When i tryed to connect it with usb to pc it said MTK6225 Found. 2.Yes it is 12 Pins. 3.I don't know the + and - of battery to know where to place the cables (cause the battery cover is blank) so i tryed to play with pins without luck. The most common pin (+-) didn't work. Let me know how to find with multimeter the battery pins and i will get back to you tomorow with greater pictures and more info. I also have no idea how to open it and i'm afraid i might break it. Thanks for spending time with my problem. |

Member: 148515 Status: Offline Thanks Meter: 19,534 | hello! please take battery and check with multimeter (voltage measuring mode) where is "+" & "-" battery terminals. connect pinfinder "crocodilles" to correspondent phone terminals. Check that phone powers On and then run pinout search. Dont forget to set L12C cable type and mt 6205-6227 MCU type and hold phone power button pressed all the search time! |

Member: 148515 Status: Offline Thanks Meter: 19,534 | hello! OK, in this case we are sure, that pinout is not in system connector. any handsfree port? maybe worth to examinta them too. L3A or L4A connctor. if no luck: we must look for test points disassemble phone and search for test points on PCB. post PCB picture here, maybe someone will recognise it |

Member: 870970 Status: Offline Thanks Meter: 1 | Handsfree port is the same were i put l12c cable. I cant use these cables. There is another port were the extra keyboard attaches. I marked it with red color in the pictures and also the pins which i tested with multimeter. Test points are under sim1 like i marked with red color in previous pictures. The problem might be with ground cause its the last pin and its covered with black color. Please tell me what testing should i do..... Also i saw in the manual page 21 it says something about changing pinfinders config. What's that? Thank you for trying to support this phone. http://www.imageshack.gr/view.php?fi...8ga8wvibx3.jpg http://www.imageshack.gr/view.php?fi...23c9y6bekd.jpg http://www.imageshack.gr/view.php?fi...dmddai0y85.jpg http://www.imageshack.gr/view.php?fi...vklor4zttj.jpg http://www.imageshack.gr/view.php?fi...77ka6uqx50.jpg |

Member: 870970 Status: Offline Thanks Meter: 1 | I checked the pins from both ports ("side" l2c - "down" keyboard both) with battery and both of them showed 4.10v. With pinfinder i get 4.90v. I used the pins from the pictures i posted above and the ones that matched with voltage. If you want another combination tell me. |
