Dual-SIM patcher for Sony phones

META-INF/com/google/android/updater-script mounts /system and, if needed, /vendor, then runs tmp/patch_dualsim.sh.

Tasks

• Read model from LTALabel partition
• Set ro.telephony.default_network based on model detected from LTALabel
• Set persist.vendor.radio.multisim.config=dsds
• Change ro.product.vendor.model to <Devicename> Dual (AOSP)
• Change all references of the single-SIM model name to the dual-SIM one
• Patch /vendor/etc/vintf/manifest.xml to add a second instance of telephony-related HALs

How-to

Simple create a .zip file with the META-INF and tmp folders included, then flash via TWRP.

For reference, a copy of the kagura dual-SIM manifest.xml is included in vintf/ds_manifest.xml.
