Z3C lollipop update ota?

I'm using my Z3C on T-Mo USA which does not officially support the device. How will I be able to obtain Lollipop once it's released? I won't get anything from T-Mo because that will only be for the Z3 and not the Z3C. Will an OTA update be pushed via Sony directly? Thanks in advance.
i think there will have an OTA update,if not,you can flash 5.0 tft through flashtool anyway
There should be an OTA... it's how I got the last update from Sony and I bought an unbranded, unlocked phone from a retailer. Whether it will be pushed or not is another matter. Might have to check for a software update yourself.
Ok. Thank you very much.

Sw update C150B140

Hi. I have a L09C150B140 from cosmote Greece.
Is there any update to this version?
Can I find this version and keep it for warranty purposes and just debrand to an other firmware?
Thanks.
Probably there is not an update available, probably you have the stock rom of your carrier, will recommend you to debrand the device and change you update area oeminfo, you shouldn't lose your warranty because you are flashing and installing an original and stock rom of Huawei.

Debranded UK users

Has anyone who debranded in the uk got OTA update passed B166?
yes, i got 182. I am now on 361 manually updated

9.1.0.326

Anyone installed 9.1.0.326? It's showed up on Firmware finder but not sure if to update to it yet?
Why would you install .326 when .328 is approved and it is recieved as OTA?
No it's on firmware finder, I'm on O2 UK so OTA is about a year behind everyone else.

Rom flash

My phone model no is SM-G970U And sprint firmware preloaded But imei is a Verizon unlocked one. Actually It's imported from usa to Bangladesh. Now I dont get ota updates Which firmware now I will flash
I flashed Verizon firmware last month But it didn’t Work.
Is it safe to flash a stock rom of build no: SM-G970U1(XAA)?
AND IF I DO SO, WILL I GET OTA UPDATES?
Yes you can flash XAA, but you will probably not get OTA updates. Usually, carriers only provide OTA updates when they recognize the phone and it's on their carrier-ROM.
That being said, these phones are too old anyway, so they are not expected to get many updates going forward anyway. They may get a few more quarterly-updates, but not monthly and no new OS versions. For this reason, I wouldn't worry about OTA updates and if you still want updates just apply them yourself via ODIN.
