Member: 42553 Status: Offline Thanks Meter: 23 | Problem with chinese Vertu I've an Ascent RM267v (Ferrari) in hands. I've tried to find its pinout using pinfinder, but the phone makes beeps (sometimes) when using pinfinder, and the software can't detect its pinout. Of course, I tried to deactivate power-on sounds (well, the phone vibrates ALWAYS when it's turned on, and it can't be deactivated). But I can power on the phone plugged to pinfinder, so I think that it isn't the problem. I've found that you've this pinout in pinfinder list, so I've selected it (I though: well, I can't find the pinout by myself, but they did it.. great!). But I'm trying to read fullflash in chinesemiracle software, and it isn't possible. The phone isn't detected. I've tried also inverting pins, changing TX to RX and viceversa, and I wasted my time. I hope you can help me. Best Regards, |

Member: 148515 Status: Offline Thanks Meter: 19,534 | hello! sometimes phone makes sounds while pinout search. just ignore this and wait pinout search end. if phone can be powered On from box power- pinout has to be found. Increase finder activation tries to "20" and repeat search |

Member: 42553 Status: Offline Thanks Meter: 23 | OK I did some investigation: CPU is MT6225. RX 4, TX5 (I found pinout by disassembling its original datacable). I'm trying to read its fullflash with infinity, but no way! Log: COM8 [VCP0] selected module v3.11 Device: Autodetect 6205-6227 NOR Checking data, wait... advanced flash detection enabled Action: read flash ====> Boot ... Press and HOLD Power button now ! 19200 fixed Connecting, wait... error: boot phase#1 failed Release Power button now ! in case of initial connection problem: on/off "Boot baudrate autoselect" Boot Fail Finished, time used: 3 sec Remove/Install battery now ! It only recognizes the phone if I try with it's battery. Powering the phone with pinfinder, it does nothing. BR |

Member: 42553 Status: Offline Thanks Meter: 23 | Hi! I looked at PCB test points, and I found TX, RX, GND, VBAT and ON. Following Infinity Box pinout (1 VCC, 2 TX, 3 RX, 7 & 8 GND) i've soldered my cable directly at these points. I've solder PIN2 (TX) to TX point. PIN3 (RX) to RX point. PINS 8 & 9 (GND) to GND point. It didn't worked, Infinity can't detect the phone. At last, I tried soldering PIN1 (VCC) to VBAT point, so I can try without battery. But that doesn't helps. Any idea? BR |

Member: 42553 Status: Offline Thanks Meter: 23 | OK problem solved! Maybe TX and RX signals aren't in the phone connector (I suppose). But I can work with PCB test points. Thank you a lot for your help! Best Regards, |

Member: 360073 Status: Offline Thanks Meter: 2,181 | Find Rx .tx Signles easyyy HOW TO FIND RX .TX SIGNLES . It is tasted and also you can test it. 1 step is, we need to find GND from phone. 2 step is, we should power on phone (operation with dead phone: phone must be 100% dead by software)and take multimater put it to voltage. 3 multimeter (-) line put it GND and with (+) line check each connectors , and usually Tx= 1.8v or 2.8v and Rx=1.7v or 2.7v (it will be change by processor but strongly 1.7v or 2.8v not 3v or 4v) This way is too easy and you will save a more time. |
