Member: 2298646 Status: Offline Thanks Meter: 16 | You need to add ImeiSign, PubKey, PubKeySign as well under IMEI2 in the cert file, check through YouTube video if needed. Search up cert edit dual Sim repair, all shown there. If it doesn't work I'll check out my dual Sim cert and post how to do it here. Last edited by benjamen50; 05-12-2018 at 01:54. |

Member: 2298646 Status: Offline Thanks Meter: 16 | Here is what cert file should look like, imeisign2, pubkey2 and pubkeysign2 should be same is the imeisign, pubkey, pubkeysign. ;Z3X Samsung CERT file ;Please do not edit this file [cert] Model=SM-G935F SerNo=xxxxxxxxxxx IMEI=xxxxxxxxxxxxxxxx ImeiSign=xxxxxxxxxxxxxxxx PubKey=xxxxxxxxxxxxxxxx PubKeySign=xxxxxxxxxxxxxxxx IMEI2=xxxxxxxxxxxxxxxx ImeiSign2=xxxxxxxxxxxxxxxx PubKey2=xxxxxxxxxxxxxxxx PubKeySign2=xxxxxxxxxxxxxxxx I know SM-G935F works, but I have never tried it on the SM-G930F version which is non-edge. The main board has SM-G930FD, SM-G930F/W8. So I assume the hardware is there but the same cert procedure and dual sim tray applies. When doing dual sim you do not use imei repair, patch certificate at all. All that is needed is read the cert, edit the cert that was read and saved, write the edited cert to the phone and that's it. It will even survive factory reset / updates as it's cert. |
