Member: 1787203 Status: Offline Thanks Meter: 23,741 | reply Dear User, The device modem rejects all the Communication with the chimera tool method. That is why the method fails. Now what you can try to do is to reflash the device. If you can use an older firmware and then run the IMEI REPAIR service once more. Best regards Sab Chimera team Quote:
