maybe your imei starts with 0499xxx , this the result to change only the baseband flash ic , you must to change baseband prosesor too , for avoid imei mismatch if your imie is 0499xxx you cannot activate and have a valid unlock ticket from apple , even if your phone is factory unlocked your only chance by software its hacktivation and wait for unlock sw based solution , or even better a hardaware based solution  | |

Member: 401547 Status: Offline Thanks Meter: 8 | ....... I think not, because the Nand flash has ECC, an automatic error correction. And if on the programmer to change the serial number, it will be recognized as an error and corrected. |

Member: 978845 Status: Offline Thanks Meter: 5 | 3 years ago that is the same problem of iPhone 3G when flashing IC to change the serials to become factory unlocked. Changing serials or chips related to baseband or activation tickets will have activation problems. Up to now there is no solution for this |
