keep me updated if you solve your issue

working like a treat! Many thanks mate! I just modified my single SIM tray using a razor blade to make room for the second SIM.

can you provide pictures of the sim tray modification please??
Also in youtube I saw that someone has used both Sims and an SD card, could this be even possible??
Also, does this procedure works on oreo Lightrom?

Hi, I want to convert S7 edge G935T into dual sims support?

I'm on U3 stock ROM, never modified.
It is not clear for me: can I just use Z3X and clone IMEI to SIM2 on my vanilla stock ROM + TWRP?
OR I must pre-flash U3 combination ROM from first post, then make all TWRP magic, and then clone SIM and lastly flash stock ROM again?

Stock ROM Support for Dual SIM?

HEY GUYS
we know that after 11/9/2018 we can not do patch cert because the new security
this way can restore original imei in addition to restore the second imei too
now let us start the steps

first flash recovery twrp
enter the phone to recovery
then choose MOUNT
and make mount efs
go back
then chose ADVANCED
File Manager
chose EFS folder
on the bottom right of the screen mark
chose delete
then back and enter to download mode directly
and flash U3 combination file download from
now format it from recovery
then reboot to system
we notice message tell us there is error in efs folder and reboot press reboot
the phone will restart and the orginal imei has restored
now root the phone by kingo root (Temporary root) this root is gone when reboot system
after root open z3x tool (you can use cracked z3x 29.5) and make backup cert (read cert )
and we edit the cert that we backed up it tow
to know how to edit the cert go to this

copy lines from imei to pubkeysign and add after imei number 2 and after imeisign number 2 and PubKey ,PubKeySign to look like this

after that re write the cert that edited by z3x tool (write cert)
now flash the phone official rom
to repair wrong SN (Serial Number):
Open Root Explorer and grant access to superuser
Change mount R\W in root
Open folder root\efs\FactoryApp and find the "serial_no" file
Open in text editor and change the value with your correct serial number, you can look at behind
Save the file and make sure the serial_no permission 0644 rw-r--r--.
Reboot your phone
and enjoy you get s7 g930F DS WITH LAST SECURITY PATCH

Hello stock rom support to dual SIM? we must need to use custom rom as my idea. it's not correct?

 

[KINGSMOBILE.LK]

We must need to use custom rom?

we don't need to use dual sim supported custom ROM to enable to dual sim?
