Since our dear Sony Brazil decided to release in our country a Digital TV-capable LTE model and since this model seems to be sold only here, I thought it would be a good idea to create a Brazilian-specific thread so we can discuss any features, details or problems specific to our device.
While the Brazilian Xperia Z2 has just been released in our country (and, therefore, there is still very little information or data available for the D6543), I thought it would be a good idea to present some specs of this device in order to avoid or, at least, reduce the number of questions people (and specially newcomers) might have.
Differences Between Models
Most of the Z2 specs are the same on all models (D6502, D6503 and D6543), such as the same processor (Qualcomm's MSM8974AB), 3 GB of RAM, Adreno 330, 5.2" Full HD IPS screen and so on. The only differences between the models are:
1 - The networks:
D6502: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz | GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
D6503: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz | GSM GPRS/EDGE 850, 900, 1800, 1900 MHz | LTE (Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20)
D6543: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz | GSM GPRS/EDGE 850, 900, 1800, 1900 MHz | LTE (Bands 1, 2, 3, 4, 5, 7, 8 - no bands 13, 17 and 20 here, so forget about the 700 MHz 4G/LTE when our government/carriers finally manage to use this frequency, once the analog TV signal is cleared and made available for mobile networks)
2 - The Digital TV receiver
Well, this speaks for itself. Unfortunately, it is still the 1seg standard.
Apart form these two details, there is apparently no other differences from our tupiniquim model and the one sold internationally. The Xperia Z2 White Paper can be found here. There is also a far more technical datasheet on our devices which can be found here.
Despite both devices being different, you CAN flash a D6503 firmware on you D6543. You will lose your DTV app. You can try to restore it through Titanium Backup, but the app will force close (you'll only install the app, but not the necessary system files and whatever is inside the Brazilian firmware's Kernel, so it absolutely will not work at all). If you don't care about DTV, you can use a D6503 without any problems or worries at all.
3 - Rooting, custom recoveries, bootloader unlocking, etc.
At this moment I can only say what I have experienced so far, and, with that regard, I can confirm to you all that you can do pretty much anything you want in that matter as if it was a international 4G/LTE Z2 (D6503).
Rooting tools (at least for the .314 firmware) work as they should (I've used this one in both my Z2 and my Z2 tablet, but there is also this one that should work too - these are the only ones I'm aware of). TA Backup tool also works as it should.
For custom recoveries, I've only tried [NUT]'s XZDualRecovery (v.2.7.154) and it works like it should. Haven't ran into any problems yet.
You should be able to unlock your bootloader just like any other Sony device, but I'm honestly unable to confirm it 100% since I haven't (nor do I intend to) unlock mine.
Generic BR | Customization Version: 1281-5466_R5C | Firmware version: 23.1.A.0.690 | FTF File: Link (1.37 GB)
Here is the pre-rooted flashable.zip file with the 23.1.A.0.690 Generic BR firmware. It was created using PRFCreator v0.8, the FTF above, SuperSU v2.46 and XZDualRecovery v2.8.8. You WILL NOT need the original FTF file posted above since I included everything in the flashable zip file, just flash it with a recovery of your choice (I use TWRP) and you are done. I've tested this on my device and it works perfectly, no issues so far. Since this new Lollipop firmware is very much different from the stock JellyBean and KitKat firmwares, it is highly recommended you do a factory reset before flashing this. Use it at your own discretion - it worked perfectly on my device and it should work just fine on yours, but don't blame me if it goes thermonuclear.

Pre-rooted update package for version 23.0.1.A.0.167: Link (1.04 GB) - MAKE SURE YOU CHECK THIS THREAD BY @norti BEFORE YOU FLASH THIS. DO NOT BLAME ME IF YOU BRICK YOUR DEVICE. You'll need the FTF file posted above to complete the update process. I used that FTF file, SuperSU update package v2.37 and @norti's Z2-lockeddualrecovery2.7.154-BETA.flashable_patched.zip, so make sure you check the thread and at least thank him for his work.

(*) I have deleted these files from my Google Drive account in order to clear up space for future updates.
There is also a folder on Mega with some FTF files, in case someone needs an alternate download link (courtesy of MarcSant).
This works on ANY Xperia Z2 (D6543).
Your Xperia Z2 does NOT have to be rooted.
Your Xperia Z2 does NOT have to be bootloader unlocked.
This does NOT re-lock a SIM unlocked phone (unlocking is ONCE and PERMANENT).
This does NOT unlock your bootloader.
(Thank you @Apollo89 for coming up with this 4 lines on your Xperia ZQ firmware thread - I think they'll help reduce any doubts newcomers might have)
Since this is an international forum, I'd like to remind my fellow countrymen that we have to post things in English here, as per Forum Rules. But we can also post things in PT-BR, as long as we post it in English first.
Special thanks for contributing:
@hitsukun for the info on Vivo's firmware and customization number.
@sighted and Gilson Cristo for Vivo BR's FTF.
@#BR for the info on Claro's firmware and customization number.
@MarcSant for the alternate download folder on Mega.
@IaguCool for developing and releasing XperiFirm for us. Managed to get the customization number from both TIM and Oi and easily download and create any FTF when they come out.
@ogunja for the Link2 on the Generic BR 17.1.2.A.0.314 R5A FTF.

@norti for this thread on how to create a pre-rooted update package for firmware version 23.0..1.A.0.167.
Moderators - I understand that there is a policy of avoiding country-specific threads for the sake of keeping things simple and direct, but I'd like to ask you guys to open an exception and keep an opened mind in this case since the Z2 model sold in Brazil (D6543) is available only in here and that may raise some problems very much specific to our device that may not receive the proper attention of the general modding community (such as finding a proper FTF file for our model, issues with the DTV, apps or the available LTE bands on this model, baseband issues and so on). Since this device has just been released here and it is a top-of-the-line device (which means it is very expensive in our country) it has not received any support as of today in Brazilian forums yet, so people may be coming here with a lot of doubts regarding this specific device.
If you guys believe a thread such as this is not important, feel free to close or delete it.
