Canceling last update

Hey all,

I update my z3c 2 weeks ago and since then the phone **bleep**!

i think the main problem is a memory licks on the 5.1.1 but can't be sure.

the battey used to last for 60-70% at the end of the day and now i need to charge after a few hours,

the client itself works so slow its sad!

any how, i wanna cancel the last update and come back to the 5.0,

any one knows how can i do that?

It has been suggested to reinstall Lollipop with Sony PC Companion.

Backing up my firmware. How can I do that?

Hello! Grinning Face

Since I'm having "dark thoughts" about downgrading to KitKat, and since I'm pretty much a noob on mobile devices, for my own safety, I want to know how to make a back-up to my actual Lollypop, just in case everything goes wrong.

Please help me, and thank you in advance.

 

p.s. I saw a little conversation here on the Z3C threads, but there were this 2 guys talking: one said to use SUS(which I don't know what it is) and the other one saying that is not available anymore.

 

p.s.s. Really need help. This 5.1.1 version of android really ruined my compact, as the message app went crazy and **bleep**ty. And all this under the big shadow of the big issue called: less than a half battery life, comparted to previous versions of android. Now, for a few days, weeks, moths, I went to Nokia E5,.. I just couldn't use the phone with so many deffects. It was like watching the phone "suffering" Slightly smiling Face) But let's not forget what we were talking before. Please help with the back-up.

You can use PCC instead of SUS

You have two options, either contact your local Xperia care or use flashtool

How to downgrade z3 from Android 5.1.1 to previous versions?

I recently purchased the z3 and was reluctant to upgrade it to the latest version of Android but after a while I gave in and I don't like the feel of it. Is there anyway I could downgrade thanks in advance.
