how to flash a sony xperia xz1 that has been totally wiped

[Android Central Question]

ive got an xz1 g8343(8341 in the us) and it randomly stopped working for no reason havent had it for more then a year and went to connect it to my pc to try the xperia companion pc program and it doesnt recognize the phone to install the software/firmware. so i went and did some digging and found out my device completely wiped itself of everything. sony program EMMA doesnt list any services it can do with the phone. and apart from custom roms which i cant even find one for my exact model im totally lost beyond sending to sony and spending alot more then the phones worth to fix it...anyone able to help?

Welcome to Android Central! I'd guess that the motherboard failed. Is it still under warranty? Hopefully you were backing up your data on a regular basis, for just such a contingency ...
