It is possible to flash XZ2 dual Indian version firmware to XZ3 to get the VOLTE feature in India
Your idea is experimental. If you flash the Same Model It will work, or else It won’t won’t work. XZ2 dual to XZ3 may not work Because the VoLTE bandwidth configuration will differ.
If I flash Xperia xz2 H8296 Indian firmware to H8266, it will work or not…
Thanks for your reply
May be It will work. But, You will not get the Mobile Network and sometimes It can brick your mobile. Don’t flash different Model number firmware. You can flash different region, But It should be within your model number. You can adjust the settings to get your mobile network. Why You need different firmware?
I have a single sim Sony XZ2, can I flash the firmware of XZ2 dual sim on it, in other to use two sim cards? I am currently in Germany. Thank you.
If you have Two SIM Slots physically present in your mobile, You can do that. If your mobile is a Single SIM Variant, It may be an Experimental. You Can Use One Physical SIM and One eSIM. The eSIM should be compatible with your Mobile Operator.
