Anyone??

Pretty sure you'd still get the OTA once its out. The spark models are still on 5.1, just checked on my Z5.

It doesn't matter what network you use your phone on - it's still a Spark branded handset.

When the Spark OTA update becomes available your phone will be able to be upgraded. This won't always (but could be) at the same time as it's available for Vodafone handsets.

The local telco's have to OK the update.  If you don't want to wait then you can flash the "Customized AU" firmware via flashtools

You don't need root or an unlocked bootloader as they are real sony firmware.

Best thing about using the "Customized" versions are they are updated by sony and don't need local telco's OK for release.

Have a read of http://xperiafirmware.com/8-firmware/123-sony-xperia-z5-e6653

Spark sells the E6653 and under flashtools/xperifirm they are listed as Telecom NZ

If you use the link above i suggest creating your own ftf file with the "Customized AU" firmware from flashtools/xperifirm.  

I have been using the android marshmallow on my z5 compact from spark running the customized AU for the last few days, its like a new phone.

I've tried the Customized AU firmware with flashtools, the update is really nice. Unfortunately I use semble frequently and I had to downgrade back to Spark's firmware as the AU 6.0 firmware is not approved with semble.

This is correct Semble needs the correct firmware that has been approved to be used with it.

I don't use Semble so I don't have this issue :)
