I'm currently on holiday in turkey, and whilst in the pull down settings enabled VoLTE, the system ui immediately died and now I can no longer unlock the phone, I'm only able to access the edge screen, no soft buttons function.
I can boot into twrp and access the terminal.
Any ideas how I can dig myself out of the hole?
I'll write a thousand times, don't fiddle after I sort it.
I've also got a laptop here so I was thinking of downloading and flashing the latest multi Cisco.
Any ideas welcome!
Some more information, the other setting I changed at the same time was wifi calling.
I'm hoping that somebody knows there they are stored so I can pull that file over and revert the settings.
I've checked build.prop and it doesn't appear to be there.
