[Guide] How to turn S7 single SIM to S7 dual SIM [Exynos pho

Mar 2, 2018 2:06AM PST

Hello,

Requirements:
   Phone must be rooted
   Need a gsm software: Z3x, Chimera, Octopus or GCKey
   Make a phone backup of efs and certificate

Steps:
  Connect your phone to usb (make sure oem unlock and usb debuggin is on)
  Make DM+MODEM+ADB connection allowed by calling *#0808#
  Read your phone certificate using a gsm box
  Open your phone certificate and duplicate everything seen after IMEI line    by copying and adding 2.(example IMEI2, Pubsignkey2 etc)..Write back     your new phone certificate
  Your phone is now dual sim
Mentions:
  This won't change your IMEI so it won't trigger law in countries where IMEI changing is illegal.
   In case you don't have gsm box or you need help you can contact me.   I tested and done it on multiple exynos versions(g930f, g930wCool and it worked.
