Xperia Z5 Premium doesn't recive the android 7.0 update

[AlexTM]

HI! I have a Xperia Z5 Premium, with the region in Spain. I found that my device gets a new software update, Android 7.0, but when I tried to update, the device said "Your device is up-to-date". I tried to update with Xperia Companion, but it said "Cannot check for updates".

Any ideas how I can update my phone without flashing it, please?

Hi @AlexTM;

First of all I would check if the phone is really up to date or with an available update. Please check your build number and phone model under settings >system about phone, and your costumization firmware under service menu>information (dial *#*#7378423#*#*).

Also what do you get when you insert your IMEI in the Support page update area.

Here you are:

1299-1506-R4B

And, I forget to say, i already checked on sonymobile.com if an update is available by entering the IMEI, and also I checked on xpericheck.com if the update is available in Spain. I am living in Romania, but, how i say in the description of the discussion, I purchased the phone in Spain.

@AlexTM;

That's odd because you should have the latest build number firmware that is 32.4.A.1.54. Wich one do you have?

Do you have by any chance rooted the device unlocking the bootloader?

[AlexTM · Accepted solution]

Yes I have unlocked the bootloader, and i have twrp installer as recovery. But i just found I can repair system with Xperia Companion and will be installed lastest version (android 7.0). Anyway, if I will lose twrp recovery because I can install it again.

Also, thanks for the all help!

Ok @AlexTM, that explains it, unlocking the bootloader makes you loose your DRM security keys and access to the regular updates.
