So if you selected usa band now you know how go back to your bands. Do the same.

Der is no option to change it

[Q] Xperia TL network selection

Does the Xperia TL from AT&T allow manual selection of available networks? For example, can a user force the device to operate on 3G when a 4G LTE signal is available?
Thanks.
You can do this on most Android phones. On the Xperia there is a setting for network mode, and on phones that don't have this you can access a special menu by dialing *#*#INFO#*#* where you can select network mode.
Thank you for that hidden menu, crabnebula.
The reason I ask this is because AT&T is known to remove features from stock versions of phone OS's (other than iOS that is). Manual network selection is one of them, but I can't confirm what models have that feature deleted.
Can anybody with an AT&T Xperia TL confirm this?

While you can get to that menu you can't change it from LTE (preferred)/WCDMA/GSM It always stays as that even if you select something else.

If you add the WAP.CINGULAR APN and enable it, you can change the settings type from WCDMA/GSM to GSM or WCDMA Only. The LTE option goes away.

You flashed it wrong, Now you have to reflash to the ATT tft and then flash the xperia tft excluding the base band to keep LTE

It's possible those two people unable to connect to the LTE network, have the wrong apn selected (you'll need to select the apn specifically for LTE. (it's in the forums here).
You'll also want to go into *#*#4636#*#* and make sure LTE is enabled.

[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

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.

Hi I use the C6602 as well and i recently flashed mine. This might be asking too basic a question but did you go to "Xperia" under Settings and select the "Internet Services" option to reinstall it? I panicked at first when I realized my internet wasn't working but after I did this, it started working fine.

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.
