How do I go back from Marshmallow to previous Lollipop

[Dna77]

Hi,

After latest update in August my z2 tablet is consuming alot more battery, and I'm experiencing some other minor problems. 

I don't want stamina mode, as I want my tablet in full power mode, every app asking for use is also annoying. 

I don't see any improvement on my daily use, so I need to rollback from this latest update. 

Can anyone help me?

You will need to use either flashtool or xperfirm or contact your Local support

Hi Dna77,

I am sorry to hear this, sometimes a new update can take some time to settle and get to work effectively, however, if there is no improvement, then you can run through with a Software repair on the device.

It is possible that the update has not installed correctly and is causing some issues. I have supplied instructions below on how to Backup and then software repair.

backup using Xperia Companion

software repair using Xperia Companion

Let us know how you get on.

Hi Jake, 

Thanks for the feedback, 

I´ve restarted in safe mode, ive instaled xp companion and performed repair, but the batery still drains very fast. i think that thats unfortunally a feature from this update.

Now, how do i rollback to previous version?

Recently upgraded to Android 6 version and completely unhappy with it.

First of all battery doesn't last even 20 hours, while before it lasted for 2 days.

Screen is too sensetive and gives error messages for no reason.

How can I get back to previous version or patch the existing??? So annoing!!

Hold on did you perform a software repair? It's quite normal after a major software upgrade to suffer some issues, and it's not related to Sony in general. All Android devices suffer a bit after a major one. Try software repair and let us know if that solve your problems.

After the update, my home and back button is not working properly and I don't know what to do? Tried factory reset but still it doest work, been using glove mode for the meantime but it's really a hustle... Can anyone from Sony help us with our issues?

Mines also done the same, no home, back button to speak of and no notification bar. absolutely worthless update. Am now struggling in so many ways! I wish Sony would actually do something to help instead of just saying that the screen needs replacing as has been said on a thousand other threads.

Clearly there is something wrong with the update and admitting to this and trying to find an actual solution would be extremely helpful!
