Re: Downgrade the xperia z2 to kitkat

You have posted in the wrong forum...this is the Xperia 5 forum, not the Xperia Z2 forum..

Easy to get the 2 mixed up though!   Smiling Face with open Mouth & Smiling Eyes

The Z2 forum is here!

Strangely, it's under the name Xperia Z2 Forum.

 

But I see you haven't posted in there, so best to try there first.

Re: The Easy Way for Downgrade Xperia Z2

Unfortunately there is no official way to downgrade an Android version.. however you can try to flash the device but be warned it will void your warranty and remove DRM keys from your device. Head on to XDA FORUMS to know more

If you don't know what the DRM keys are for, then you have a lot of reading to do.

Google them or READ THE INFORMATION AT THE TOP OF THIS TOPIC, before blindly flashing the phone, as some features will be removed permanently.
