unbranded xperia z LTE updating - Xperia Z Q&A, Help & Troubleshooting

Hey everyone, so i'm a brand new unlucky owner of an unbranded xperia Z as i'm stuck on .434 jelly bean until sony decides to we (unbranded phone owners are worthy of an update)
So i'm looking at the prospect of doing the system update the hacky way and got just a few questions...
How can i check if i have an locked or unlocked botloader?If i unlock the bootloader i void my warrany?
If boot loader is locked is it absolutely necessary to unlock it? Because i'm afraid of loosing perks such as Bravia Engine...
Whats the most stable rom running latest jelly bean iteration for xperia z?
Thanks for answers in advance!

if you want to update your phone you don't need to unlock your bootloader.... all you have to do is flash a ftf rom

When is it coming ? Jan the 31st ....So today ?ok Not today but weeks later http://www.xperiablog.net/2013/01/3...oming-firmware-version-9-1-a-0-489-certified/ better late then never though I wouldn't expect never for such a new phone that would be just ridiculous
Just out of interest, when an FTF file becomes available, could you then flash it with flashtool on a stock ICS locked bootloader?
Judging by past firmware updates, it's taken 2/3 months for Orange to push an update.
Yes, or you could flash the 303 generic UK and ota to current. You'll then get jelly when Sony says not ee.

I wonder how I flashed my V with its locked bootloader to Xperia VL's firmware using Flashtool, then.
All you need is matching signatures, and all similar models share them.
Yes good news

Sorry but you've got that wrong, you can use flashtool to flash an official ftf onto a phone with a locked bootloader, I've done it loads of times with my xperia's. In essence if your locked to a network orange, t-mobile ect then you can get the region generic ftf and flash it with flashtool to debrand your phone
What you can't do is flash custom ROMs which require a custom kernel.

Thanks for the responses guys, I thought it would be possible, the only reason I ask is that I've flashed ICS firmwares to the T in the past, but wasn't sure with it being a different version of the OS.

Please read before continuing to facepalm yourself.
Flashtool does not require your bootloader to be unlocked. It also does not even you require your phone ot be rooted.
Flashtool can be used on any xperia phone regardless. It does not require fastboot

Wait...we have a bootloader unlock for TL on ATT?
So this is 4.1? I got the update in sony bridge, but updating means I lose my root right? (locked bootloader)
Yes when you update to different firmware you will lost the root privilege

Not always, there are ways around it. But in general yes.
Once the new firmware hits users with locked bootloaders we will see if we lose root, but then we will also find a way to root the newfirmware or find a way to update that does not lose root.

some help for a newbie?

Usually a carrier locked xperia has a permanent locked bootloader. Don't be surprised if you can't unlock it.
Just a heads up before you do too much research.
thanks guys!

It is an issue if you want those highly customisable roms such as cm,pac etc. I rather lose be2 than not having the chance to flash those. But now there's a way to save your ta before unlocking bootloader so it's all good for those who want to unlock bootloader and still keep be2 for future use.

Yeah viper rom was always great in htc phones. I know not it since htc sensation. CM always seemed broken. Always something isn't working what works on other roms. I always wondered why CM always seems to have issues with things.

Would unbranded firmware install fine on branded z1?

I have C6906 from Bell and i can't wait for bell to release 4.3
can i just flash unbranded 257 using flash tool
and use pc companion to update to 290?
my phone is not sim unlocked yet / never touched boot-loader / didn't even bother rooting it.
I am still on stock 534
thanks in advance guys
yes
As Greg already said - yes.
Branded version is same ROM but without a craps from your carrier.
So, not only you'll be able to flash it without any problems but you'll be very happy when you see that your phone is little bit faster and "cleaner".
Also, if you want to unlock SIM lock (if it's available on your device), you can do that by simple code order via Internet.

I've got the same phone from bell. First thing I did was flash an unbranded ROM. Bell has a few bloat apps that I hate. Best part is if you flash unbranded you don;t need to wait for updates. I got my update through PC Companion the day it was released.
Search the forums please.

I'm also on Bell with a c6906 and have done exactly what you are asking about and you will be fine. In case you didn't know we can't unlock our bootloader so the fix in 4.3 does not benefit us. Still 4.3 is a great update, loving the phone regardless.

Copy *#*#7378423#*#* to your phone dialer and it will open up a service menu. Go to Service info then Configuration. The last line in that screen will say Boot loader unlocked allowed: No
So we are outta luck.

Losing IMEI and SIM not accepted problems happen when you downgrade, not update.

You need a custom kernel. And to install one, you need an unlocked bootloader.. which will break your warranty on many cases, so be careful

Already unlocked my bootloader,
Sorry, I'm a rookie at android devices, where can I get a custom kernel
And what do i need to do after that?
EDIT: It seems we replied at the same time! haha.. nevermind what I said below then....
Also note that a lot of our Xperia T's bootloaders are NOT unlockable. There is a code you can dial on your phone to take you to a service menu where it will tell you if your bootloader is unlockable. If it says No, then your bootloader simply cannot be unlocked. Then you can join the many of us who patiently pray and wait for someone out there to crack or work around it
