I really want to get Lollipop back on my z3 compact, the Marshmallow update removed Stamina mode and Ultra Stamina mode which ruined the phone a bit for me. The battery lasts way less on a typical day and I've got an 11 day trekking holiday coming up that I really want to have ultra stamina mode for.
I know officially Sony doesn't want you to downgrade but that you can apparently do it with flashtool. To be honest I don't quite have enough tech know how to make it happen and I wouldn't normally try but I can follow instructions.
Can someone tell me if these instructions will let me downgrade to Lollipop from Marshmallow?

A friend of mine thinks following them'll be fine but it's bugging me that the advice is for updating to Lollipop rather than downgrading to it. If those are the right instructions that's great but I still need a little help.
I've tried to follow them already, my phone's backed up and I've downloaded the software, drivers and the right firmware but as soon as I started up the flashtool program and put the USB in my phone flashtool gives me a message saying: "Error: cannot sync devices github.com/Androxyne/devices.git: Cannot open git upload pack". I tried to look it up but the only advice I can find to do with that error message is to reinstall flashtool and to make an exception in my firewall and neither of those solutions helped.
Thanks in advance for any advice you can give.
