Can not switch Z3 to LTE mode.

[Robby-Nightmare]

Hi. I bought a new Xperia Z3 from Canadian carrier Wind Mobile. They do not have LTE service. After 3 weeks of horrible service, I bought the phone out, and moved over to Virgin Mobile, (which does have LTE), I had My Z3 unlocked, put in the proper APN, and the phone will not switch to LTE, in fact there is not even an option to switch to it. (in Settings, more, mobile network, network mode). I went into (*#*#7378423#*#*) Service settings, network mode... I see LTE settings here, but when I select it, it will not switch, it always goes back to WCDMA_PREF. Is there a way to get my phone to switch to LTE mode?

Thanks for your time!

Rob

Ok... Will I find that on the Sony site? And will that wipe my phone? And am I able to do that Stock/Un-Rooted?

Please advise.. And thank you for all your help! :smileysmileythumbsup:

Flashtool on the above link its a third party program not from Sony, Sony has its own software BUT you will have to unlock the bootloader, not worth it, just download 

Flashtool

FTF (firmware) 

and follow the steps 

It's quite simple

It will delete everything on your phone.

Anytime, did it worked?

[Robby-Nightmare]

No. I can not get flashtool to work on my computer. It won't start up. It keeps going into a loop, so the program won't start.

What if you re-download flashtool and try again, also check if you have the latest java
