Yes i have tryed Xperia Companion, and tells me that Android 8 it's the latest update available (in the phone says the same in support) i have also tryed the developers mode in software repair, and nothing, the thing is that i had ANDROID PIE in january , and now with the downgrade that Sony's tech support did on the phone System, i cannot update it and get the latest features that i have before like the camera features and others, I even have an Email from Sony Care that tells me that v. 52.0.A.3.202 it's avaliable for my device, explaining all that i need to do with Xperia Companion, but Xperia Companion, says that Android 8 it's the latest version, i also tryed in different computers with the same results.

I have a Xperia XZ2, the phone doesn't update, still has Android 8, i have seen my phone softwarversion and it is: 1311-7915_126.96.36.199.51, the customization version is: 1316-0773_R1A, this is for central Europe. My phone originally updated to android 9, but due to a malfunction in the speakers it was sent for repairs to Sony´s tech support, and came downgraded to Android 8, i conntacted Sony support and they told me that i need to wait, it has been 2 months and i still can't update the phone, the only thing that i see is that this customization version it's not updated in Sony servers and maybe that's why it says that my phone is updated. I attach a screenshot of my computer to show what Sony support page indicates when i check the latest update with mi IMEI number. Can you help me?. Thanks Jimmy P.D . The phone it's SIM-free
