Hey brothers.
Following the footsteps of the Brazilian D6543 Xperia Z2 thread, and since our dear Sony Brazil decided once again to release in our country a specific 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 (again, just like in the Brazilian Z2 thread).
Differences Between Models
Most of the Z2 Tablet specs are the same on all models (SGP511, SGP512, SGP521 and SGP 541), such as the same processor (Qualcomm's MSM8974AB), 3 GB of RAM, Adreno 330, 10.1" Full HD IPS screen and so on. The only differences between the models are:
1 - The networks/storage:
SGP511: WiFi-only 16 GB model
SGP512: WiFi-only 32 GB model
SGP521: 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 and 20)
SGP541 (3G-only version, no idea where it is sold): 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
SGP551: 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 - just like the Brazilian Xperia Z2, 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. Fortunately, and unlike the Brazilian Xperia Z2, this one is the full seg standard.
Apart form these two details, there is apparently no other differences from our tupiniquim model and the ones sold internationally. The Xperia Z2 Tablet White Paper for the SGP511 and SGP512 models can be found here and the one for the SGP521, SGP541 and SGP551 models can be found here. There is also a far more technical datasheet on our devices which can be found here.
Now, I tried flashing both the unbranded UK and DE firmwares for the SGP521 on my SGP551 and when flashing without wiping my data and in both occasions it resulted in a bootloop. But flashing it with the full wipe did the job. In other words, based on my experience, you CAN flash a SGP521 firmware on our SGP551, but you HAVE TO WIPE everything (unlike the Brazilian Xperia Z2, in which you can flash a D6503 firmware on our D6543 without any wipes).
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 Tablet (SGP521).
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.

Notes
This works on ANY Xperia Z2 Tablet (SGP551).
Your Xperia Z2 Tablet does NOT have to be rooted.
Your Xperia Z2 Tablet 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.

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 Tablet model sold in Brazil (SGP551) 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.
