Hello guys!

So I live in Rio de Janeiro - RJ, Brazil.

I just purchased my Xperia Z2 model D6503.

Im experiencing an odd issue. My phone isn't connecting to my carrier 4G network!

As far as I know this model is compatible with our LTE network (Band 7 / 2600mhz).

Does anyone know what could be the causie of this problem? I am fairly sure the issue isn't on my end.
[Xperia Z2 General] carloscarvalho:
Great... i flashed Carbon Rom and my phone is bricked now... so sad...

Any tips ?

The phone doesnt boot... if i hold power button he keeps buzzing... and if i plug the usb cable a red led turn on and off

Edit: Resolved using Flashtool + D6503_17.1.1.A.0.402_CE.ftf
[Xperia Z2 General] Luhccas-X10:
First hours with Z2 are just AWESOME!

Everything smooth as silk!

Gorgeous screen, outstanding sound, nice feel in the hand, nicely finished and simply superb!

Nice, Sony!

It is what Z1 should be!

My dream coming true!

Saw your PM before your post here :p

These are my APN configurations and I've been able to perfectly use Claro's 4G here in Rio as well (been living here for a few months now).

Already sorted the issue.

Many thanks [MENTION=4519790]Tiu Fiu[/MENTION] for the attention. I honestly don't know what was the causing the problem.

I will tell my story:

I bought my z2 in a Claro pre-order.

Three weeks later, i received everything fine, nothing to claim!

But, 'CURIOUSLY' my 4G did not work to!

After some calls and goings to Claro, i changed the chip that i received for other one and "tadááá".

In other words, i receveid a chip that does not work 4G !!

They told me that i need to buy a new one, paying R$10,00. haha

I opened a call in Anatel and i'm waiting now.. hehe
[Xperia Z2 General] Tiu Fiu:
Well well well, unfortunatelly I've got my first bug to report...

Yesterday my wifi connection just didn't worked at all... It was a pain to get it connected to my home network and when it finally connected, it wouldn't receive anything, the upload arrow would work almost all the time, but the download arrow just wouldn't show up... Never...

I tried to reflash the german .402 FTF, but, no joy, still didn't work... So I went to work and I found two threads on people reporting the same bug (here and here) and, apparently it is happening a lot on .402 and .438 firmwares...

It seems that this issue is caused by some sort of interference with the bluetooth (bluetooth works at 2.4 GHz and wifi can work at both 2.4 and 5 GHz, depending on the configuration of your wifi router). One of the solutions I tried was turning off wifi, keeping the bluetooth on and rebooting the device - when it restarted, the wifi turned itself on (location based, and I was at home) and voilá, it was working again...

If it happens again I'll try and set my router to 5 GHz (it is currently set at 2.4 GHz only) and I'll leg you guys know.

Just wanted to post it to give you guys a feedback... Unfortunatelly we are not bug-free, even if on the old .55 firmware there wasn't such a problem...

Hi, another one going to Sony.

I was using Galaxy Note 2, but it's my second bad experience with Samsung Devices.

My Note2 headphone jack failed after 4 months of usage, and I had a lot of issues with Galaxy S1 too.

A question for you Brazilian users. Did you put some screenshield or using some protective case for Z2?

I stopped to use Galaxy Note2 cases because it starts to lose the painting on plastic parts even protected, but generally it did not slip on my hands, so the smartphone don't fall on the ground frequently :p

If the answer is yes, any slim case to use with this smartphone? I hate that large cases.

Thank you.

No case here, just a screen protector on the front and the back (Spigen Ultra Crystal)

Hello,

I Have Brazilian Xperia Z2 (D6543) but I want to install D6503 Firmware. My question, has any type of port Digital TV program to Internacional Firmaware?

Nope, none.

Flash and you lose it.

Hello there,

Does the .402 version came out for 6543? Anyone know if it is possible to root this version?

I am not shure if I apply TWRP with fastboot in the BR .402 will do loop or maybe works without wifi and other things like CWM with BR2.55.

By the way, I am running the DE .402 with TWRP and SuperSU on my D6543 and soon I will update my signature.

But .55 is rootable via Easy Root method.

4G LTE

Long story short:

I've flashed "UK - unbranded - 1282-0226" and the 4G simply didn't showed in any situation.

I live near São Paulo and i visited various clients during the week including Av. Paulista and Av. Berrini (Best 4G signal) and nothing.

So i changed today to "Germany - unbranded - 1281-4640 (1278-4770)" which says LTE besides 4G and guess what? Nothing so far.

So here goes the question, which version are you guys using and how it's 4G (LTE) working?
[Xperia Z2 General] Tiu Fiu:
D6543, using D6503 .402 from Germany and I've got LTE running as it should...
[Xperia Z2 General] TicoVillas:
APN and Others;

Can't figure't out what's wrong man;

Tiu Fiu can you help me? What's your APN Settings?

And at "Provedores de serviços" are you conected to the "Claro 4G"? Becouse i can't conect to it, it says it was unable, and ask to check if my SIM is inserted and if the network is available, which of course it is as it shows at an option.
[Xperia Z2 General] Tiu Fiu:
That's is very weird mate, my APN settings are exactly like yours, the only exception is the APN name itself (I renamed mine to just say "Claro"), but that is supposed to be just a name.

The only thing I can think of that might be wrong is in Claro's end. Maybe the network just does not recognizes you SIM card as LTE-enabled. My advice to you is to call Claro itself and ask if your SIM card status with Claro is LTE-enabled. Perhaps some configuration on their side is messed up.

If it doesn't work, just go to a Claro store and buy a new SIM card, 10 bucks and Claro is pretty mich forced to set your definitions on the new card. Just make sure you want a LTE-capable one.

4G da Claro

Bom..vou contar o que aconteceu comigo

Usava um chip da claro no pré pago no meu atual telefone IPHONE 5s e o 4G era muito bom.

Um dia resolvi testar o chip da vivo durante uns dias...

Insatisfeito pela pouca cobertura da vivo na minha cidade..resolvi colocar o chip da claro novamente no telefone.

Só que depois disso o 4G nunca mais pegou !!! Liguei na claro e disse que estava tudo normal. Fiz a troca de sim card 3 vezes ( chip Virgem mantendo o mesmo numero) e nada de 4G aparecer. Ninguem da claro sabia responder o pq o 4G nao funcionava mais neste chip.

Depois de uma semana sem 4G voltei a loja e comprei um chip com um numero novo pra fazer um teste e para minha surpresa apareceu o sinal 4G

Utilizo esse chip com um numero novo ate hoje e está tudo certinho o 4G nele, já no chip do antigo número até hoje nunca mais voltou o sinal 4G

No meu caso foi um BUG no sitema da Claro.

[Xperia Z2 General] Tiu Fiu:
[MENTION=4895687]Envious_Data[/MENTION] already replied on your post, but just to add up to what he said, unfortunately we D6543 users don't have an update to our Brazilian-specific device, .55 is the only firmware available. You can flash any D6503 firmware you want, but you will lose your DTV (if you ask me it is a small price to pay to keep your phone updated, even though it is Sony responsibility to give us the updates and in a perfect world Sony Brasil would be capable enough to give us the updated firmware - again, one of the problems of having a Brazilian-specific device).

If you want to keep your DTV (and stick with the buggy .55 firmware), you can flash this mod to make sure your speakers work in stereo most of the time, as it should. Keep in mind that on the .55 firmware you can only use the v1.0 and you will need root and a custom recovery (my advice is to use [NUT]'s XZDualRecovery)

Best regards.

Where's our Z2 in PTCBR??
[Xperia Z2 General] Tiu Fiu:
PTCBR? You mean the certification forum for wireless mobile networks, PTCBR? Nowadays the american body for cellular certification? If you mean the LTE band for our country, it is band 7 (Source).

If you are asking about the Brazilian Z2 in the PTCRB product page, it is not listed (my guess is why bother to certify a product in a USA body that is going to be sold in only one country that is not the US, Canada or in Europe). The D6503's page is here. But it is not always accurate.
[Xperia Z2 General] Luhccas-X10:
Strange... Z1 have an specific page there

Why our Z2 (d6543) are not there?
[Xperia Z2 General] Tiu Fiu:
No idea. Maybe the C6943 Z1 was sold on other countries? I don't really know if it was. Or perhaps the D6543 is still in the process of being certified - I guess that is up to Sony, really...
[Xperia Z2 General] Atlas:
But if I root it, will I lose something? I mean, warranty,etc.

And, I know there is a way to root .55 without unlock the bootloader, how about the latest software? And how did you still with 4G connection working? Which country are you using?

Instaling D6503 Firmware

Good Afternoon,

if I want to install the D6503 (Xperia Z2) firmware, on my Brazilian Xperia Z2, I need mark any option in FlashTool?
[Xperia Z2 General] Tiu Fiu:
You will technically only lose warranty if you unlock the bootloader (at least I never heard of anyone being denied warranty due to rooting).

I'm on the latest firmware (17.1.2.A.0.314), rooted through this method here created by cubeundcube and posted by [MENTION=5169444]RyokoN[/MENTION]. I believe there is also a new version of the Easy Root Tool by [MENTION=3975929]zxz0O0[/MENTION] (v11) which seems to work on the new firmware, but I haven't tested.

As for LTE, it is working fine here (both in São Paulo and Rio de Janeiro on Claro) and I'm using the German (DE) firmware, all OK.

If you want to do a fresh install, cleaning up the entire internal SD card, than keep marked all options in the "WIPE" section. If you don't want to lose your data, unmark options "DATA" and "CACHE".
[Xperia Z2 General] Sayid_the_Lost:
I'm also using .314 (german) + the cubeundcube root method and every is fine (using Vivo 4g at Sao Paulo)..

German firmwares always work like a charm because they have the same 4g bands as we do.
[Xperia Z2 General] Tiu Fiu:
Actually German carriers also use bands 3 and 20, while the 4 Brazilian big carriers use only band 7 (also used in Germany). The big thing to keep in mind here is that all firmwares for the D6503 have the same basebands, regardless of the location. We can use any country's firmware if we want to. I just use the German one because it is usually one of the first to receive updates as they come, but on my ZL (ZQ here in Brazil) I used Russian, Nordic and even the "Commercial and Journalists" (internal Sony) firmwares without any issues at all.
[Xperia Z2 General] TicoVillas:
Still no 4G

Just an update in my situation;

I've called Claro and they checked everything and said that should work since on their end was everything right, just for a clean conscience the operator said he would send again the configuration to my device, i had to wait one day, turn off my phone and after 5 minutes turn back on and ta-da, still no fuc**** 4G.

So today i went to the store and talked to the manager, he tried some configurations and still nothing, he said that there's nothing wrong with the sim or cellphone and that really should work, since my phone even "sees" the network, now i have a protocol and claro's TI will look into my case. Great.

When i have some news i'll keep you guys posted, maybe my situation will help someone in the future.

Wish me luck, lol.
[Xperia Z2 General] Atlas:
Lol, I've flashed German latest version, and LTE works fine here(Rio de janeiro)

But one question, I just flashed, did I lost my TA files? If no, how can I save them?
[Xperia Z2 General] Sayid_the_Lost:
Did you put your sim on another 4g-ready smartphone to test the network? If the awnser is yes i definitely recommend you to backup your phone and reflash the firmware, sometimes something goes wrong and reflashing solves this problems.

.314 root

Hey dudes, easyroot is working in .314?

I just flashed .314 but easyroot don't pass when i hace to click on "make it rain" in the cellphone, on the cell part everything seens to work but the script keeps waiting for the explit.

Any ideas?
[Xperia Z2 General] Tiu Fiu:
Alright, one at a time.

On Easy Root Tool's thread there is a new version, v11, that the OP says should work on .314. I rooted using this method, the only difference is that you need to set up ADB PATH on Windows, which is an easy thing to do (Google it and you should find it).

There is a tutorial thread here explaining what you need to do.

If you just flashed the new firmware using FlashTools, then no, you did not lose your TA partition.

You can make a backup using this method, but you will need to be rooted so the tool can access the necessary files and back them up. You don't need to be on the latest .314 firmware to backup your TA partition, any firmware will do, as long as you are rooted.

Goog luck bro... I can only imagine how annoying it can be...

Best regards to you all.

[MENTION=5732563]TicoVillas[/MENTION], what do you exactly uses on xposed? I'd like to use it too, but I did some wrong things on my gs4 in the past haha.

Cheers
[Xperia Z2 General] TicoVillas:
Xposed

Sup Geiger;

I use a good amout of modules, Tinted status bar been one of the best ones and UDN (Hide navbar) that is awesome since i have full screen without losing the navbar functionality.

Look at the screenshots, that's the ones i have, and for me was very easy to install, just download from the apk Xposed repository and install, the phone need to be rooted but the bootloader can be locked or unlocked after that inside the app you need to install the framework and just then you can use the modules, every time that you install a new module you need to activate and reboot (soft reboot do the job);

If you need some more help just ask away, and if you want more information on any specific module too.

Ps. German .314 is workin smooth and with working LTE/4G

Maybe this one:

or this:

Can't be sure, they say that to work you need to delete your account, activate the module, reboot and add again, but is for AOSP devices, don't know if it will work in stock Sony ROM.

Backup

Guys, i think i'll update my Z2 (D6543) with the last stock rom from D6503. Don't need the DTV.

I'll backup my TA partition for security. Do i need to backup the stock rom? Currently i have a debrand .55 firmware.

I don't want to use another rom, so i don't want to unlock my bootloader.

To backup the stock rom, i need a custom recovery, can i do this with a locked bootloader? Or i need to unlock it?

Is there a problem in root rom .314? Thanks for any help.
[Xperia Z2 General] Luhccas-X10:
You don't need to unlock your bootloader to use another ROM.

You don't need a custom recovery to backup your TA, you need this to backup your current ROM.

You just need root to make TA's backup.

:good:
[Xperia Z2 General] Tiu Fiu:
I'm gonna divide it up to make things easier for all of us.

You can backup your TA partition by just rooting your Z2 and running the Backup Tool, that's all. No need to backup the stock ROM just to backup your TA partition.

To backup your ROM you will need a custom recovery, yes, but that has nothing to do with locked or unlocked bootloader. Search for [NUT]'s XZDualRecovery on the Cross Device Development section and install it. No fears or worries, the custom recovery will not in any affect your bootloader.

You'll only need to unlock your bootloader if you want to flash a custom Kernel, as the locked bootloader prevents changes to the Kernel (or, at least, flashing a Kernel that is not signed by Sony). As custom ROMs also invariably have a custom Kernel embedded on them, you'll also need to unlock your bootloader if you want to flash one of them.

As the recovery

is not

a part of the Kernel, there is no need to unlock your bootloader to use one.

Rooting on the .314 firmware is stable and works like a charm. I don't know about the other methods available, but I've used this one, which was the first to truly and successfully root the .314 firmware, on more the one occasion and it also works perfectly. Just remember that you need to setup the ADB PATH on Windows to use it. No worries, it's an easy thing to do. Just Google it and you'll be fine.

I'm more interested in that, but will take a while to arrive: http://www.clove.co.uk/microusb-to-magnetic-connector-adapter

I had that problem on my ZQ as well, but I managed to find a simple solution: go to Settings -> Location -> Google Location Report and disable both items there (Location Report and Location History).

I would also uninstall Google Search with Titanium Backup (requires root, since it is a system app) and reinstall it through the Play Store, but I don't know if it helped or not. In the end, the Google Services Battery Drain was effectively gone.

As for the magnetic charging dock, nope, haven't found it yet, only on Mercado Livre on an absurd price (from R$ 225 to 325,00). I bought a genuine one from UK (eBay), but it hasn't arrived yet.

Using DTV on a D6503 firmware

Just to give you guys an update, [MENTION=2605312]Luhccas-X10[/MENTION] and I have tried to somehow port the necessary system files (apk, odex, lib, etc.) for using the DTV app on the D6503 firmwares, but we've had no luck.

Luhccas-X10 found the files the DTV app requires to properly use the DTV ability of our D6543 and sent them to me, so I could test if we could make it work by simply placing them in the proper folders and assigning the proper permissions. No joy, it didn't work.

He even decompiled the apk itself only to find that it is somehow coupled with the kernel and/or the baseband, so I'm guessing it is something hardware-wise that requires a connection with the Android OS (hence the coupling with the kernel and/or baseband - maybe a built-in DTV-antenna or a receiver chip somewhere).

Whatever it is, it is much harder than we thought and messing with it can be much more dangerous that simply tweaking a few files on the system partition. Perhaps it also explains why Sony BR is not updating or bothering so much with keeping our Z2 on par with the international model.

Anyway, just wanted to let you guys know.

Best regards...
