How to upgrade to Oreo?

[barMan]

Hi,

First of all, Sony support don't want to understend my problem and help.

My phone doesn't got any update/upgrade since 7.1.2 (about one year).

How to upgrade to Oreo or patched version of Kitkat?

It is not unlocked nor branded or something like this.

Sony support ask me to wait but I see that something is wrong with updating my device.

I bought two devices the same time. One is on Oreo now, second stops to update.

Updates availability depends on a specific characteristic of your device called "customization version". You can check this version by dialing the code *#*#7378423#*#* the tap on "Software info", if you want me to check if this specific customization version has the update released or not I can help you with that.

Is that an Xperia X?

What is the model number?

[barMan]

From all aspects I can verify it is Xperia X, model F5121 with Android 7.1.2 from Sony.

It's strange but, this customization version is not listed. This might mean that this unit is a prototype and was not intended for sale. Where did you buy it from?

[barMan]

I bought two devices from iBood.

On this one I installed 7.1.2 from Sony Concept programm. I suppose, that this is reason of my troubles.

I don't found any warning there that it is software death for my phone, alwow there was warning that it can't be uninstalled.

Oh, that explains all.

Let me mention a friend who knows more about concept: @najodleglejszy

@barManSony Concept was a different branch of software. it's not being updated anymore, so you'll need to get back on the regular software track. to do that, you'll have to perform a software repair using Xperia Companion. just make sure you make a backup of important data, as your phone will be wiped in the process. once the process is done, your phone should be running either Oreo, or regular (non-Concept) Nougat, which you'll be able to update to Oreo.

Thanks, I try to do that.
