Xperia Z2 does not update to 4.4.4

Please help me!!

 

I am from Romania and I have a normal Sony Xperia Z2 phone (not rooted or locked or anything else).

There have been more than 3 monhs since the 4.4.4 update has been released and I am still running 4.4.2!!! I love Sony, but this is getting me really mad!

Will I ever get the update as Sony promised?

 

P.S.: I have an Vodafone SIM card inserted, if that is relevant anyway because my phone is unlocked (not by me, it is carrier-free).

Re: Xperia Z2 does not update to 4.4.4

Yes you will - As long as you don't unlock your bootloader or root then you will have no issues - Manual flashing as per the guide does not require rooting or unlocking the bootloader

Re: Xperia Z2 does not update to 4.4.4

You can manually flash another country's firmware however to answer your question - Before generic handsets get the update the networks have to all authorise the update, I'm not saying they have to release the update but they do have to authorise it - Then Sony will be authorised to release it to generic devices - So before blaming Sony blame your country's networks or blame your network for not releasing it to you

I don't understand a lot of what you mean, but you said that I can flash another country's firmware. HOW CAN I DO THAT?? Will that ruin my phone? 

You are the best member of this site if you can help me out!!!!

And one more question: if I do that will I get next updates? (like lollipop)

Re: Xperia Z2 does not update to 4.4.4

Create your own firmware file using this guide

 

Manaually flash your phone using the file you created above using this guide - (Software here as the link in the guide is wrong) but don't use the firmware file on the guide use the one from above but the rest is exactly the same

Re: Xperia Z2 does not update to 4.4.4

As long as you follow the guides there shouldn't be any issues - Even I had to learn how to do this and never messed up yet - Fingers crossed
