[Q] Update Xperia Z (C6606) to 4.2.2 (10.3.A.0.423)

Hi
Can I flash the stock ROM (FTF) for the C6602/C6603 on my T-Mo US version (C6606)?
I own a Xperia U (ST25a) and I could flash any stock rom intended for the ST25i as long as I avoided updating the baseband/radios, wonder if it is the same for the Z.
Any info, greatly appreciated

It seems that you can - http://forum.xda-developers.com/showthread.php?p=43755021

And I can confirm it works as well.. Been running that update all day. Much better than what the phone (C6606) comes with..

so no issues with LTE functionality etc? and what method did you use in order to update to 4.2.2?
thank you for your help

Here is the link to the lastest flashtool I used:
http://forum.xda-developers.com/showthread.php?t=2162907
And here is the firmware (out of all the .423 updates this one seems the most smooth)

This is the guide i followed and is well written:

Just a reminder, by updating and debranding your Z, you will lose all T-Mobile specific features such as wifi-calling, hotspot (just use another one from play store), T-mobile TV, etc.
if you need to revert back to stock T-mobile here is the firmware:

Your picture shows 6606 as the model, but you give a link to a 6602 firmware. How'd you manage that?
T-mobile Xperia Z

the firmware is indeed 6602 but hardware wise we are the same so it works fine. I edited the build.prop file so my device appears on softwares that i am a 6606 and not a 6602 (e.g. play store, xda app, etc.) also make sure when you flash the firmware that you "check" the box on the right that says "exclude" baseband so that you retain the T-Mobile radios (e.g. LTE, etc.)

So i've successfully flashed the 4.2.2 linked to in this thread, but I have no LTE either. I tried it with both basebands, and neither one gives me the option for LTE in the Mobile Network Settings menu. The first flash I did it while exluding baseband of the 6602, then I tested and reflashed with baseband of 6602, tested and went back and flashed just the baseband of the t-mo 6606. All three options provided the same result, no LTE options.

I went ahead and just installed the 4.2.2 from Spain, LTE works now. Had to locate the carrier and download all the data, but that was nice and simple. Everything seems to be working just fine now, except I have a permanent notification up top that says all steps completed. I'll figure that out and have it gone soon hopefully. Thanks for the help guys.

[Q] BL-Unlockable T-mobile Compatible Xperia Z

Hello,
I would like to buy a Xperia Z with an unlockable bootloader and I currently have T-mobile as my provider.
Which version of the Xperia Z would be most compatible with T-mobile and have an unlockable bootloader (aside from the T-mobile version)?
Where would I buy such a phone?
Would I have to make any compromises (ie data/cell links)?
Thank you very much.

There seems to be a way to flash an C6603 basebands what would enable lte for the C6602 n baseband 4. Because it actually does have lte but it is not official enabled. But u will find better info on that if u do a search on it. But it seems to be possible. Only on the C6602 not the C6603 because it has different lte basebands.

I researched hard before buying my 6606 and find it nit to work unfortunately,if u find a way let me know I'm still in my return period,lol but I've not really minded because I'm on the newest 4.2.2 firmware released yesterday,root,custom dual recovery,and solid lte,but that's my preference because I like stock roms better,the only thing I can't do is vanilla android or roms like Pac etc,but I understand it's nice to be able to unlock

Yeah on the C6602 u can enable lte option with flashing a C6603 rom. Basebands sadly can't the flashed to a different baseband. The C6602 has lte 4 and some others but never official lte like the Nexus 4. That has lte disabled but with some unofficial ways u can enable it. I am glad u understand. Trust me if I could I would flash lte baseband that will work in my C6603 for the USA. Sadly I can't.

Sent from my C6603 using xda premium

Well what lte band uses t mobile? The C6602 could get lte 4. Because it has lte build in but disabled. U need to flash a C6603 ftf to it to make lte option be available. It seems to work but the speed supposed to be not as fast as it should be. Kinda like on the Nexus 4 lte worked but wasn't as powerful or fast as it should have been.

It will be months till tmobile gets it,they only released it a week or two ago, who knows they may skip it to 4.3 but there's no way if they were gonna update this fast they would have released with it,just flash it through the flashtool root not needed
Sent from my C6603 using Tapatalk 2

I was hesitated about flashing and rooting my Z, but I just did everything and I am running 4.2.2 and rooted with my t-mobile Z. You can search hear to see how to flash and root.
Root is quite easy. Change some settings on your phone, plug, click and ready to be rooted. Flashing is bit more work to be done but they are also easy such as install drivers for your Z in flash mode (like DFU mode in iOS) to make Flash software to work.

I have the Tmobile 6606 and I tried flashing both German and French 422 updates and couldn't get lte to work no mater which way I flashed with or without baseband and the exact apn settings with lte preferred click. Just won't work for me.

Flashing stock firmwares on this phone is not much different than doing the same on Samsung and HTC phones. A few things to download and that's it. If you've ever used Odin with a Samsung phone before, it's a very simaler process.

You definitely still have t-mobile Z baseband.
Your stock baseband hasn't changed.
Here is my stock and 6506 baseband. I just flash baseband only.
With 6506 baseband, I don't get t-mobile LTE even though it has LTE_BC4

so the same gen, almost the same.. flash Russian or Turkish firmware. that's all
there is no other way except the both. I am sure you ve got weak reception. technically you CANNOT force the phone only to get 4g either via any app or baseband model. But you can upgrade your baseband to get really better reception, if available, 4g.

Still testing, but seems to work good on SM-T555 on Nougat.

Download Force 4G LTE Only 2020 from Google play .
Run the application, press the SIM 1 only or Android testing button. You will enter two LTE Switcher options and also 2 Android testing options.
You can try all of them which support your phone.
