Member: 7337 Status: Offline Thanks Meter: 0 | Sorry I've meant phone F-bus interface! Phone itself is working ok. I've tried to reflash it (need to change PPM), but I can't When I connect it with LogoManager, PC-Locals or WinTesla with M-Bus cable it's working OK, but with F-Bus does not So I decided that phone F-Bus i-face is damaged. Or maybe not? |

Member: 14006 Status: Offline Thanks Meter: 0 | I meet this problem too The problem is I think in cobba I ****ed cobba with hot air gun and the fbus is working now, But be careful with hot air guns, you can kill your phone permanently so I advise you to let your actual ppm. Best regard Blueman |

Member: 1060 Status: Offline Thanks Meter: 10 | Dimka, If you think, phone have problem , from NOKIA service menual, Fbus tx/rx, 3 part link. they are MCU, CCONT, IR if your cable to flash other phone is working, then it must not cable or SW problem, most time, Fbus TX can not set High after Mbus is set low during flash init. , please try clean phone Fbus contact pad first , then to check CCONT ..
