HI ALL,
I updated to 4.3 without thinking first. I don't have an unlockable bootloader so I cannot apply root on that rom. The only rom I was able to root is .532.
I went to the [FTF Depository] Sony Firmware Releases (Latest: 14.2.A.0.290 - C6833) **UPDATED* thread and downloaded the [STOCK ROM] [FTF] Xperia Z Ultra (C6806) 14.1.B.1.532 "US Retail"
I'm on bell network from Canada but since it was the same model I only though that the input language would be english only. The problem is I don't have network signal. It says, Invalid Card, Emergency Calls only.
Then I tried to flash the baseband from [STOCK ROM] [FTF] Xperia Z Ultra (C6806) 14.2.A.0.290 "Generic US" which works on my phone but still the same baseband.
I'm confused. Is there a way to use the .532 firmware on my phone ? I have a C6806 from Bell with locked bootloader wich sucks btw.
Thanks
Sylvain

Unfortunately If you have a locked bootloader, and what sounds like a locked SIM for Bell only, you can only use the ROM that your carrier provides you with. You'll need to find someone in Canada with your device (ultra) and then get them to send you the FTF file.
and then flash that.
Its the only solution know of

Thank you for your reply, really appreciate it. But I found a solution
After digging in the Q&A I found someone said that he lost his IMEI after downgrading from 4.3 and it was the same thing as me I had 0000000000 as IMEI. I tried multiple thing, and finally after downgrading to .532 excluding the baseband, upgrading to .257 and downgrading again to .532 fixed my issue with the invalid card now I have my LTE, signal and root back online.
Did you exclude the baseband when upgrading to .257 and downgrading back to .532?

The guide in general is now very simple to follow is starting from .290, there is now just a single file to flash, although it will say that the model no. is a c6833 at the end, but that will change back when you flash the correct ftf.

Hello!
Today I get my Xperia Z2 branded by T-Mobile in Poland. I want to root without voiding my guaranty. I have FW 23.0.1.A.0.167 running Android 4.4.4. I'm know that i have to downgrade my firmware, but I can't find matching firmware for my device and brand. I've searched in this topic of course -
[FTF] STOCK FIRMWARES for Xperia Z2/Z2a (D65x3/D6502/SO-03F) [20141116]
Can somebody help me?
Greetings from Poland!
May I downgrade from 23.0.1.A.0.167 (4.4.4 update) to 17.1.2.A.0.314 Germany - unbranded - 1281-4640? Is that won't brick my device?

You can downgrade to any ftf until its for your model. you might want to try and use xperifirm for ftf download though. you might find your phone's ftf.

No problem mate...will wait.......hopefully it comes out this week
Xperfir, is showing 242 for 6 markets, all 6833 (Saudi Arabia, Switzerland, UAE, Thaliand, France and Mena Latin)
post screenshots..
For those are with 6833, i have already install the update, is the 5.0.2, only "issues" i have found:
- No XLOUD on Walkman APP, but have the EQ and Clear Audio etc...
- Camera quality is worst than on 4.4.4, more granulated, if you take a picture and zoom it, is worst than ever, even worst than in my Xperia SP!!!!
- My phone is heat more than in 4.4.4, in 4.4.4 i have ~24/25º, now on 5.0.2 have 27.5/28º (nothing special i know, but it feels in hand more than before.)
Until now is only that i can see is the problems, XLOUD is not a problem, i can live without XLOUD...but Camera is something i can belive the update fck'd up!!
how is possible the camera is worst on 5.0.2??can u post some comparisons?
Just got done updating my C6806 and everything is working perfectly. I am able to use my LTE from T-Mobile as well as send and receive picture messages. Sony's Lollipop feels very smooth. I have not encountered any bugs yet.
So for the people asking if its safe to update outside of your region, the answer is yes and it works extremely well.
Trying to download with xperifirm, but every time it stops at about 15% and i can't resume, only start from 0... so... that sucks, yeah

Are we able to root this FW via Towelroot or other current one-root process?

If you flash a different ROM, i suggest you back up your FTF. To do that, search xda how to make an FTF.
You will need to revert back to your original firmware region to receive updates for that region or flash FTF via flashtool
Quote me in case you expect a reply!
Good Luck
Hello, here is a TWRP-flashable pre-rooted original Sony's Lollipop firmware for Xperia Z Ultra. It was made with the aid of Flashtool, Xperifirm and PRFCreator. I thank the authors of these wonderful tools. I encourage you to make your own pre-rooted firmware yourself, but if you are just not interested in such things and your Xperia Z Ultra is C6833, you can just grab it here.
There is just a couple of requirements to get this flashed: any recent version of TWRP already installed to your phone and a microSD memory card. So yes, you need to find a way to install TWRP on your Ultra somehow. Note: ClockworkMod may seem to install this fine also, but in my case the system actually was not properly installed and numerous errors did emerge, so I do not recommend use it for installation.
Here is some technical info regarding this firmware:
Phone: Sony Xperia Z Ultra (codename: Togari)
Phone Version: C6833
Origin: Stock (original by Sony, nothing removed)
Branding: No Brand
CDA: 1276-7737
Market: Russia
Operator: Customized RU
Firmware release: 14.5.A.0.270 / R2D
Here what have been integrated in the firmware by PRFCreator:
SuperSU: v2.46
LockedDualRecovery: v2.8.15
And finally here is the link to the firmware itself on Mega.

You're welcome. I will share stock pre-rooted ROMs once Sony will release them. I think we may expect at least an upcoming update to 5.1.
Hi,
I am in CrDroid CM12.1 based ROM with TWRP recovery, and would like to flash this ROM. My bootloader is already unlocked, but you have mentioned that you have integrated "LockedDualRecovery", does this mean my bootloader will be again locked ? Do I need to unlock bootloader again to flash CM based ROM, if I would like to do in future ?
Thanks

Hello. No, your bootloader will stay as it is. LockedDualRecovery is just a piece of recovery software.
