[Q] Purchased Xperia Z3 D6603 International unlocked

Hey all
I have purchased Sony Xperia Z3 D6603 International factory unlocked from Amazon.com ... i am currently using it with AT&T network and everything is fine like calls and LTE.
1. But when ever i boot the device i see Tmobile logo and few preinstalled Tmobile apps... is it bcoz i purchased it from amazon instead of directly from sony or what could be the reason.
2. Bcoz of that Tmobile logo at startup will the lollipop update depends on carrier or not.
Please let me know.
Thanks & Regards,
Kishore.

That is not international version. It is a t-mobile branded. It is propably from germany market.
Lollipop update depend from t mobile (Germany?)
But you can flash a non branded firmware with flashtool

True the device is from Germany.. Seller told that to me when i asked about warranty.
Now my question is if i purchase the same device from sony directly will that also come with tmobile branding? I see that Sony selling d6603 factory unlocked in US website.
Thanks and regards,
Kishore Kumar.

The D6603 is an unlocked version which is not t-mobile branded. The D6616 is the t-mobile branded version.

The German T-Mobile is a D6603 and you can flash any (generic) ftf for this model to get rid of the branding.

I have flashed the device with D6603_23.1.A.0.690_Customized_US.ftf... i see the option Hi-Res audio via USB is missing under audio settings also the punch feel of the front speakers has reduced slightly ... rest all working fine .. what could be the issue ? btw i did not check anything under wipe or exclude while flashing the device.
Thanks & Regards,
Kishore Kumar.

Might be an effect of upgrading to Lollipop ?...

[Q] H60-L02 dual sim update from EMUI 2.3 to 3.0

Hi everyone, I got a dual sim H60-L02 from China (rooted by the seller) and using it in Malaysia.
The shop dealer asked me not to update the phone as I will not be able to use Malaysia SIM card upon updating to the latest firmware.
Is it something to do with the baseband?
Is there anywhere I can find the baseband if I updated the phone and fail to connect to the cellular services?
Do advise / correct me should I have made wrong statement.
Thanks.

sorry but it sounds to me you've got either a clone device or spyware from your seller. try the app Z device test to check the hardware

I have L-02 type, unrooted, using it in Malaysia, 1st sim Maxis and the other one use indonesia's SIM. It's running properly for 3G. I unable try 4G coz my sim card not support for 4G.

thanks for the reply.
Just to update, as there is a small note not to update to EMUI 3.0 while in rooted mode, I had factory reset the phone and then only updated the phone to latest firmware. Since Gapps does not available in China, I installed the Gapps from huawei app centre (Google calendar and contact sync adapter are available in that app centre) and the phone works well up to now except whatsapp chat history problem.
Hope you all enjoy Honor 6 H60-L02, definitely a phone worth to buy.

I have H60L02 .. Bought in Chinese... I am in India
I want or remove chinese app ..
Even in Contacts i could see chinese.. kindly Help in rooting it to International version EMUI

FOTA UPDATE necessary FOR Reliance Jio User Volte patch required- reliance jio probl

Volte patch required- reliance jio problem after marshmallow update
The problem started to happen AFTER update 6 AND 7 . Phone is workings perfectly fine with voLTE sim
but call cracking net speed up and down and signal goes and come infrequently
but after every 30 min the signal goes and we need to switch off and switch on the sim tab to get the signal again. The problem is only only with volte sim
AND IT CONFIRMED FROM JIO TECHNICAL TEAM
SOLUTION IS FOTA PATCH UPDATE AND IT IS NOT READY IN MOTOROLA SO NEW ANDROID VERSION IS DELAYED ON OTA
SO WAIT TILL FOR FOTA UPDATE THEN WE GET NEXT ANDROIED 7 OR 7.1 UPDATE

What is this fota update?

Try wiping the device from recovery.

I have Xperia Z1 Compact and I can't make any call and can't receive incoming call with Jio sim. I have also contacted Jio care they tell me to update FOTA software, but I don't think there is nothing to update when my device is shows up to date and not any other update released in our country. Jio care misleading us.

Download the jio phone app maybe ? Also Sony is to be blamed for this. They have a rep for abandoning phones as it is

VOLTE patch

Could anyone of developers make a volte patch for xa as it is a core feature of nougat and Helio p10 also has it
But Sony doesn't want to give this feature in India Xperia xa f3116 deliberately
In nougat it's not working when I try *#*#4636#*#* setting
Volte provisioned switch could not be turned on and it were off by default
In UK it is on by default and it is supporting volte
So can anyone build a volte patch for xa???
Or
Could anyone have a solution to turn on the volte provisioned flag on in India xa
Thanks for every one who guiding me

Did you update the "New update of 9.8mb"
don't know what changed they have made in this patch, may be this patch include VoLte features.
i'm unable to update, since i have unlocked the bootloader.

sure thing!!:fingers-crossed:

Noppe that 9.8mb update had nothing to do with Volte. I checked everything can't seem to figure out what it was about maybe just some fix or something but no Volte yet ?

Yes it is not volte patch
But I think you should update to it
May be it has some fixes that are really necessary to our xa
Cause Sony is not so generous that it will give an update with extra feature in very short time from its latest update
I have listened about call log is lagging after nougat update
Not sure every one has this problem or not
But may be that 9.8 MB update relates to that problem or any other else
I suggest you to update when you have a free useless boring time to time pass with that update

I have a XA1 Dual Sim, but the situation may be same.
if you go to *#*#7378423#*#* > Service info > Software info under Current Modem Config if you have Vodafone LTE On, it has the default config, but if you have Jio LTE On, then the config changes to a Jio Specific Config, one of the reasons why my phone restarts when i change the settings between Vodafone and Jio, it needs to reload the Modem config file.
Now I believe Sony has VoLTE specific config for each of the Operator and the software is looking for some settings in the SIM to enable VoLTE Provisioning.
If anyone has root and can browse the content for the system folders /system/etc/customisations/modem/ , and could check if there are different config files for each of the Operator, take a screen shot, or may be one common config for VoLTE if all SIM support VoLTE.

Is it possible to enable volte in xperia 5 in india?

Is it possible to enable volte in xperia 5 in india? I bought xperia 5 j9210 from online. Unfortunately volte not working in india. is there any workaround? My wife is also using xperia 1 it also bought from online since sony stopped sales in india, volte is not working for that device aswell. Thanks in advance.

You may have to verify with your carrier if they support volte on the Xperia 1 & 5 at all?
if so, then then it may be a question of getting the firmware for your country/region flashed to the phone(s).

I am asking for your Xperia 5 only. Probably that same region's firmware (if it exists) on my 5 III might enable VoLTE. So far I have tried Global (Vodafone LC not Net Locked) and SEA but both haven't worked in enabling VoLTE.

@yogeshpatel7 If it's not a lot to ask from you, could you PLEASE spare 5-7mins to go through my request here (https://forum.xda-developers.com/t/enable-jio-volte-and-vowifi-on-xperia-5-iii.4467977/) and see if you could help enable this for 5 III? I hope I am not asking a lot from you and it would SUPER APPRECIATED if you could help make this work. Right now my phone is practically a paperweight as I can't make any calls as Jio is a 4G ONLY sim and doesn't work without VoLTE.
