(Q)Debranding Xperia Tx

I've Vodafone Australia branded xperia tx which also sim unlocked. I no longer use Vodafone and I would like to debrand it.
Is it possible to flash it with normal non branded Sony firmware?
Also my phone is bootloader locked and it can't be unlocked.
my reason to debrand it is i am afraid that i have to wait for vodafone to release jellybean. not sure about though.
Any help would be really appreciated since i am a noob in this regard.

When downgrading from 4.2.2 to 4.1.2, you need to wipe all data or it won't work. Why do you need the 'Generic US' firmware anyway? Does it contain any special features which you need and which are not available in 'Generic TW'? It's the worst customization when it comes to updates..

it doesn't have any special features, i don't knowt what in Generic TW firmware have. I just worry that if i flash other region firmware i won't get update over the air later. and i think the original firmware is good for me.

Today, Generic US has been updated to 10.3.A.0.423. You don't need an FTF to flash this firmware. Just follow this guide to change your customization number to 1271-0119 and install the update with Sony PC Companion: [GUIDE] Download ANY firmware customization from Sony & create an FTF with Flashtool

LTE firmware is for C6603. The C6602 contains different hardware and has no LTE support. If you flash firmware for the wrong device, you might get connectivity problems and you will no longer receive any software updates from Sony (because they check the first 8 digits of your IMEI number, which is different for C6602 and C6603).

I just updated to 10.3.A.0.423 last night using a FTF I made from PC Companion. Posted here in case anyone needs it

Just noticed that using C6603 firmware for my C6602 phone wasn't a very good idea.... Sony PC Companion doesn't allow me to update it.
After I reflash the C6602 version of firmware, will I be able to automatically update my phone using Sony PC Companion? My phone is a C6602 bought in China but the Chinese firmware has been flashed out of the device.

same issue i have a C6602 with C6603 rom on it

Were you able to get the phone back to stock? Also is there not a way of flashing the ROM without using the PC and ftf.
I prefer flashing from the phone on CWM because I'm lazy, Is that not an option for installing a stock rom for this phone?

If you find a flashable zip with stock rom, you can flash stock.
But if you have your booloader locked, chances are you lose your root, recovery and go back to barbone kernel.

thanks for the info. Im not 100% knowing if the bootloader is locked or not. I just assumed its unlocked because the phonr is rooted and i'm running AOKP on it. i guess the main reson i want ti know is because i know its not the correct rom for this phone. it works fine but it should be the one that should be for the phone. not c6603 when the phone is a c6602. would you happen to know the link for a cwm flashable rom version of c6602?

Firmware 4.3 for Xperia TL Lt30at?

Hi guys, I in Vietnam and I have a Xperia TL Lt30at, I bought it from a store in my country, now I want to upgrade firmware 4.3 for my phone. But I don't know what firmware for it, as I search, that just has firmware 4.3 for Xperia T/TX. I just wondering my phone can read my sim, can use gsm and 3G in my country, so is that unlocked? If it was unlocked, can I use it as every Xperia T (Lt30p) other and up every firmware as Lt30p?
Sorry for my bad english

Hello. I am also using Xperia TL. I can answer your questions :
1) TL can use any rom of Xperia T, not TX made for looked bootloader.
2) You can test your phone with Vietnamese mobile network. If it doesn't run, you should ask your seller to unlock network for you.

I sure that, because i have tried it. I'm using Ultimate PureXT v2.1 of DaRk-L0rD and it run properly, except general bug of xperia T

Had you used search before posting, you would have found my guide on upgrading LT30at to 4.3. LT30p and LT30a/t are the same devices. The only difference is that that a devices have LTE radios in them. Since you use only 3G network, you don't need to worry about basebands.

PureXT is based on stock. Sony no longer upgrades software for its at&t devices, so you have to use stock-based custom ROMs if you want to be up to date.

Let me get this right:
- you own LT30at: Xperia TL with USA at&t branding, not Rogers from Canada, which is LT30a
- you live in Viet Nam and you don't have 4G/LTE network where you live
- you want to upgrade the firmware to 4.3 and keep all native Sony features
All you have to do is follow my guide. There is no 4.3 coming for LT30at via Sony Update Service.
"ROM cook" stuff doesn't mess up your device because it's basically the stock ROM with some APKs added/changed. I don't know why you worry about losing at&t branding - it's absolutely useless to you since you aren't in the USA.
Moreover, flashing using the flashtool, you will lose all of your apps, settings, and root access. If you are fine with that, then do go ahead and pick any TFT firmware for T or TL from the list and then flash it.

Firmware
I tried much but failed to find kitkat or higher

You're on the latest available software for your device (C6606). It seems that T-Mo aren't interested in the C6606 any more and won't approve updates for it.
I've seen around the forum that some people have flashed the C6616 firmware to their C6606 with success. You could try that. I'm not sure if you would lose any T-Mo features like wifi calling though and it's obviously at your own risk. Nothing should go wrong though.
If you want to try, you can download and flash the latest C6616 firmware (10.6.A.0.454) by following my guide - How to package and flash stock roms in FTF format

Most people have found it better to do a clean flash when upgrading to Lollipop, so it's probably best to backup your apps and reinstall after flashing. Apart from that you shouldn't have problems if you follow my guide.

(WARNING : Since Xperia Z, sony added a new set of files I called bootbundle. Those files can be bundled from 0.9.13 and can be flashed from 0.9.13 only. To all those flashing devices from Z edition to all after Z, it is highly advised to use 0.9.13 and to be sure FTF you flash contain the bootbundle set. I've been reported of hard bricks because of missing such set of files from bundles.) copied from there
