My brother took his G935F to a shop and they did it. Search youtube and you will see its possible. |
impossible bro,........ you should change the devices |
It is not impossible ,plz do some research before saying its not possible. i will take out pics and post this week. |
brother you have single sim set, so how you say about convert it to dual sim?? can you explain us little |
please google it and you will see. |
G935F and G935D use same pcb with all readers there, you can activate in z3x. |
write Slave IMEI (with Cert), SIM2 will be activated! You can do by this way: read Cert from phone, edit Cert file, add IMEI2 Cert data like IMEI1, write to phone! |
i also have a sm-g935f Samsung s7 edge G935FXXU1DQC2 having Nougat 7.0 from middle east in which VOLTE is not working , i dont want to use 2 sim just VOLTE , so i want to convert it to India version g935fd , is that possible ? or is there any way to start VOLTE ? urgent reply please . |
Hello Guys...the mainboard of g935f and g935fd are the same. To change g935f ( single) sim to g935fd (dual), 1st run g935fd software on the unit and write any dual sim imei for the unit...voila. you have dual sim support so just change your sim tray to dual. The same procedure if you want to change dual sim to single sim...i have done it many times.:) |
hi What software are you using. thanx |

No need to flash Sm-G935FD firmware yes? IMEI2 in cert add via notepad I think. |

I think they have blocked downgrading older firmware than February 2018, I have too new firmware. Any solution for this? Older modem flashing seems to not work on newer firmware. |
Turn On your Phone. Go to Setting. Then Go to About Device. Then Go To Build Number and Press Build 8 times. Now Go back and find Developer Option. Now Turn On USB Debugging. Now Go Back to Phone Dialer. Press *#0808# and Select DM + Modem + ADB and Press Ok Button. Now Connect USB cable and Open Z3x Box. Now Go to G935FD Model and press repair From menu. Now Enter IMEI of the Phone 2 Times and press Repair Button. Mobile will ask For Adb Check Box and press Ok. Then Ask for root permission. Check Box and click Ok. Now Z3x will ask for Wrong Model Click Ok to Proceed. Wait 2 Minutes after process of Z3x Mobile Will Restart. When Mobile is In Full Menu Now In Z3x Repair Menu Press Patch Certificate. wait 2 to 3 Minutes after restart insert dual sim jacket with Sims and check signals. |
Anyone need help about convert it will be my pleasure to help |
OK I Have read out the cert, I will try IMEI2 now notepad trick and report back if successful. |

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. |
I have a small word, http://forum.gsmhosting.com/vbb/12417582-post9.html |
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. |
I have solution and i have file to convert very easy in 5 menuts you can chang |
is possible under last Android 8 ? thanks regards |
