[Q] Rooting, Unlocked Bootloader, Custom Recovery - Sony Xperia Z Ultra

So I I finally rooted, backed up my TA partition, unlocked the bootloader, and flashed CWM/TWRP. Took me forever to do on windows 8, but finally figured it out.
My question is, what effect does flashing OTA updates and/or ftf's have? Will I just lose root? Or will I lose custom recovery as well? Just want to make sure since i'm sure the B.2.257 ftf will be posted shortly and I will want to flash it!
Similarly, if I were to change the CDA to get B.2.257 OTA, would I just lose root? or would I lose recovery as well?

I don't know about ota but flashing a ftf makes you recovery and root go bye bye.

Thanks for the reply. Bootloader remains unlocked correct? So just re-root and reflash?

Yes. Only way to relock is by restoring your probably backed up TA partition.

Yes, i believe it's possible with the latest version of flashtool (+ update).
The safest way though, is to revert to stock (do a backup of your current rom&setup of course) then perform the unlock.

Alright alright.
But,if i backup my current rom (which is for LB) then unlock my BL and then restore my backup of my LB Rom,i will have a Rom for LB on my phone with ULBL.

Relocking bootloader for Sony XPERIA SP

Just flash this .ftf file via Flashtool. Your bootloader will be relocked and you'll be able to use PC Companion or Sony Update Service to update your phone.
Notes:
If you use custom kernel than before relocking bootloader flash the stock one. Or if you forgot to do it just flash stock kernel after relocking.
Your root access will persist after relocking if you had it before. But some apps will work improperly (RootExplorer v3.0 causes reboot when trying to mount /system as rw) and some apps work good (SolidExplorer, SD Maid...)

Did it by myself. Checked it twice before publishing here.
I always try and check everything what I'm going to publish.
PS There is no TA backup. There is preset.ta which contains data for re-lock.

Well as far as I have read, TA partition differs device to device. And flashing someone else's TA partition can hardbrick your phone

I totally agree. But there is no any TA partition backup in this .ftf file. There are only loader.sin (which is unique to each phone and in this .ftf it was taken from stock fw .257 - the same for all customizations and all fw versions of C5302/03/06) and preset.ta (which contains data for re-lock and that is the same for all phones Sony).
I remind that I checked it twiсe: relocked bootloader and than unlocked it via fastboot and via flashtool.
By the way, it is more convenient to relock bootloader via Flashtool using "BLU" button.
Hi, someone try to do a backup TA with flashtool?

I don't quite understand this part. I thought rooting and unlocking bootloader are two mutually exclusive and that you can execute one independently of each other. My Xperia SP is rooted using DoomLord toolkit but I don;t think my bootloader is unlocked.

flashing a FTF will remove the custom recovery and root but not lock the bootloader, but you can lock it with flashtool or by restoring the TA bckup

Z Ultra GPE Root update and Ta Back up

Now from what I understand there is no root method for this device just as yet now my question is how different is the Sony branded Z Ultra from the GPE version besides android version. I all's know that root is needed to back up the TA partition so is there a work around for your our device.
Sent from my C6806_GPe using XDA Premium 4 mobile app
The GPe version doesn't have the same type of TA partition as the Xperia model AFAIK, but you still have to unlock the boot loader of the GPe to root it.

That I understand but how is the back up of the ta partition made is root is required to relock the boot loader

You can't backup TA. You root, you lose.
Or you can downgrade (the Xperia model if that's the one you have) to 532, root it, backup TA, update to 290 and lose root, unlock the bootloader and root it again. The difference this time is that you'll have the TA backup. It's a helluva way of doing it, but it's your only option right now.

Nope, you can't do that with the GPe. Root it and lose it. It's as simple as that (for now).
Thanks for the info but I don't think the recovery is stable for the GPE its still testing and I'm not looking for a brick right now can afford another device right now so I'll just wait

[Q] I'm Stupid (bootloader locked and flashing)

First of all, I'm spanish, my apologizes of my expresions or misspelling.
That's what I've done:
1 - I've checked if my bootloader was unlockable, and my phone say's: NO
2 - Then I've installed the DualRecovery W/O root and with my phone bootlocked.
3 - Then I've tryed to flash CM11 in TWRP recovery, flashing first the Boot.img via fastboot.
4 - Device in Red Light.
What I can do to woke up my Z2? That's my record 2 hrs to **** my phone. :silly:
Firstly, it's stated in the first post of the CM11 thread that you shouldn't be using dual recovery. If you read the thread further, you'll see that it is recommended to use the recovery in DooMKernel to flash. And this requires unlocked bootloader.
Anyways, you can try using Flashtool to flash a stock firmware. Might be able to recover your phone.

If your BL is locked, you cannot install CM.... coz you cannot install a custom kernel. you should rebuild your phone using SEUS to put a good ROM.
Then you can put whatever ROM you want for LB and root it. but no custom kernel.

Hi there,
Is there any way to get root access without unlocking the bootloader. I found some ways in XDA but nothing is clear.
I would really appreciate if you guys can send me a link with a clear tutorial of how to get a new ROM without unlocking the bootloader.
I just got my Z2 which is sim locked (UK) and I can't unlock the bootloader from the official page.
Many thanks,

Yeah, working right now, then 3 questions more:
first: the phone comes with a Vodafone rom, I can put some "unbranded" rom? how?
second: I can't unlock my bootloader forever ??
and third: What is the function of recovery mode if I can't flash any cRom? Just backups?
Thanks all ^^

You can download a Generic FTF and use flashtool to flash it to your device
Once you unlock your bootloader it stays unlock till you relock
You can flash roms n manage general other stuff from recovery
