Member: 2076039 Status: Offline Thanks Meter: 648 | Have you looked through them with a hex editor? I noticed that in one of the files, the name that varies says SPC. Service programming code? Quite different from MSL though which is what I thought that GSM phones use... If you're willing, I'd be up for taking a look through these files although I cannot guarantee that I will produce results... |

Member: 2076039 Status: Offline Thanks Meter: 648 | Ummm...first off thanks for sending over the files. Secondly have you looked inside the enc files?! There seems to be part of an RSA key in it. Possibly the private key for this model? If so, this is some insanely interesting stuff. I just looked at it with my phone but ill take a closer look when i get home tonight. Im going to need to brush up on my ssl skills. Im a bit rusty. Also theres some interesting QC DM commands in there, although im unsure of the syntax. THIS is why ive always wanted GSPN access!!! Edit: you wouldnt happen to have the pubkey for this model would you? Last edited by ecs87; 07-01-2015 at 20:17. |

Member: 2076039 Status: Offline Thanks Meter: 648 | The only people who I've seen offering GSPN access has been...iffy. I don't really trust em. And I'm not interested in logging CERT files; I'm more interested in the other files that are being used during the IMEI repair process such as the .enc files. Reverse engineer the ENTIRE process and you now have a calculator with no need for Samsung's official tools. That's MY end goal |

Speaking of which, I havent been able to get a closer look because i dont have the public key to the G313, nor have i ever seen one in my neck of the woods. It would be worth it to put together a base64 encoded pubkey, throw in the already encoded base64 private key, and the value you want to encrypt. Will Samsung really leave their chin out there like that for entire models? Maybe. Isnt it worth a peek? | |

Member: 10485 Status: Offline Sonork: 100.66876 Thanks Meter: 396 | the easiest way to decrypte those files is using daseul But as GSMCN said, its only configuration file for daseul! Another info: For CDMA based model files, you can find the 16 digits PWD inside |

Member: 984046 Status: Offline Thanks Meter: 255 | And as for daseul use, now new security policy is on force. Gspn login gave you semi OTP (x days valid / region / auth level dependant) pin as part of daseul login. Haltec |
