[Q] Load US T-Mobile Firmware on D6603 - Xperia Z3 Q&A, Help & Troubleshooting

Hey everyone,
I own an Sony Xperia Z3 model D6603 and I live in the USA. I haven't had any issues with it except for no Wi-Fi calling/texting.
I downloaded firmware for the sony xperia z3 D6616 US Tmobile version and was wondering if I could load that on my D6603? I heard of others loading custom roms from other models of the Z3 without incident so I would think it was possible. I think this hypotheticaly should get Wi-Fi calling to work as it should be a software restriction not a hardware one??
Any insight would be very helpful. Hell even if you think I could give it a try and if it doesn't work I can always revert to the old rom, a boost of confidence would be great before I start tinkering with things.
Thanks everyone!

[Q] TMobile Z3 vs Sony Z3

Hey guys,
I am looking into getting the Sony Xperia Z3. I just have one quick question.
A while back I purchased the Xperia Z (C6602) from sony directly and I used it on tmobiles network. After purchasing the phone I found out that tmobile sold the (C6603). These phones are similar, however they do have different specs.
My main question is, is there any difference between the Xperia Z3 that tmobile is selling compared to the Xperia Z3 that is sold directly by sony? (other than the available colors)
Thank you for your help!!!

Two things primarily: The T-Mobile model has 32 GB of RAM vs. 16 GB and its bootloader is locked.

Also the T-Mobile one has LTE Band 12 which no other model has.
You mean 32gb storage, it has 3gb of ram
Tmobile version has band 12 and wifi calling.
And the T-Mobile is only in black and carrier branding...no thanks!

Reason I would reccomend, TMO version is the 14 day replacement/exchange period. I went through 3 and on 4th and possibly final one. If you buy from Sony directly you will be stuck without a device for weeks if you send it in due to defects only to probably get a refurbished one.
The TMO emblem is pretty conspicuous unlike Verizon so that should not be an issue.

I think you mean to say "inconspicuous" . Anyways I agree, looking at it, it's also a much lighter shade of gray/white than the Xperia or Sony logo, so it actually blends in quite well. There's also no T-Mobile branding on the front, which is really nice.
Hardware differences:
32GB Storage
T-Mobile Branding on back
Band 12
Software:
Bloat: http://imgur.com/oXLCzjj
Bloat not removed: wifi hotspot needs hotspot on plan, Device Unlock
Bloat that needs PM BLOCK: CarrierIQ
No bootloader unlock
I believe only the T-Mobile version has wifi calling.
You can opt out of Carrier IQ, the bloat is not so bad actually fewer than most carriers and they can all be disabled. For the extra 16GB its worth it. Only thing for you to care about is the boot-loader unlock. WiFi calling is also a plus.

Xperia Z3 Flashing ROM with Flashtool

Is it possible for me to flash the US D6616 T-mobile rom onto my D6603 or will it brick it.
I am too impatiant to wait for the EE software to be released to allow me to use thier wifi calling service?
Thank you
Yes it will brick don't do it.. There are plenty of lollipop ftfs for d6603 just not tmobile.
Thank you, i think I'll wait for EE uk to release there one.
I was only interested in the T-mobile US version because i wanted wifi calling! For now i am running the US version.

Obviously only Apple and Samsung are in line... they think they cover most with two major players.

T-Mobile Z3 to International version

Knowing how bad T-Mobile is with software updates, T-Mobile users will probably never get Android M update for Z3.
Wondering if there is a way to install Sony's International software version on t mobile's D6616, so we can get Android M update?
Is it gonna be stable?
Instruction would be helpful, I never done this kind of thing before.
Also, Sony might have new UI for Z3 in Sweden, maybe it will come with Android M in the future!!
What are you talking about? There has been no notice about Android M from Sony or T-Mobile. We'll probably get it 3 months after the international push.
There's no way to convert the T-mobile D6616 to an international model due to locked bootloader. But even if it were possible, you'd lose the 32GB and radio compatibility. At that point, it would be wise to sell your Tmobile model an buy the 16GB international model.

Z3 D6683? Updates?

Hi it seems I ended up getting a Z3 D6683, it's like D6633 but China version. No difference except it's modified to work with certain chinese networks. My big concern is updates, does Sony treat models like these with equality to its other variants? Right now it says its 5.0.2 is 'up to date'.
If not, is it possible to convert this to D6633?
