Use Flashtool to put back the .42 or .58 software, root it, and then update via Update Center on the phone. After the update, the phone will be still rooted until you do a factory reset.

I watched that Video but your BootLoader has to be UNLOCKED and i dont want to unlock mine till i can do the TA_Backup. which requires root
Then you will need to use flashtool to downgrade to .532 then use the offline root method, then use the TA backup tool.
Whether you will need to upgrade back to 290 before the unlocked bootloader root method, I am not sure.

Did you flash the right firmware you lost your imei due to a wrong ftf flash back the 290 you will get back imei then flash the genric ftf which is of your region ...................I lost my imei also agter flashing a wrong ftf although many says it did'nt affect whichever region ftf you flash but it happened in my case mine was also a 6802.............

flash 257 or 290 FTF with flashtool will solve youre IMEI problem.
if you want to root your ZU on 4.3 you need to unlock youre bootloader but before you unlocke your bootloader first downgrade to 257 and then
downgrade to 510 ( you wont lose your IMEI ) root your ZU and get ta backup.

Custom Roms
So it turns out I can't unlock my bootloader but can still use this method to root. Does this still mean that I can flash custom roms on my phone? I was very excited to get cyanogenmod on this beast of a phone, it'll be really disappointing if I can't.
OTA Updates
Will rooting the phone still give me access to OTA updates? And if I do still get them, will updating to Lollipop remove root from the phone?

There is no root exploit for 4.4.4 with locked bootloader yet. You can root a previous fw and flash a pre-rooted 4.4.4 rom in recovery.

There is no way to root that, at least with locked bootloader.
I kind of rushed into this
Just wondering mainly about the 'TA' stuff, from what I read - this will not affect any of that and I can unroot and get it back to warranty standard at any time by flashing, but how would I go about backing up the TA after this has completed?
Also will i lose my google auth app when this has completed because I totally overlooked that when I started and I'm worried now I will be locked out of all my accounts. lol
Thanks guys

DRM keys are only lost if you unlock your bootloader. Flashing stock ftf does not do that (exclude .ta files and use the same country/provider you bought the phone from)

[Q] downgrade back to kitkat 4.4.4

Is it possible to go back to stock kitkat 4.4.4 ftf from a stock lollipop 5.0.2 without having any issues like losing imei number or any other problems? My xperia z ultra 6833 was not upgraded from 4.4.4 to 5.0.2 with Ota. I flash with a stock 5.0.2 ftf via flashtool
Thanks

You have to wait til 5.0.2 is rootable. Check Sony site maybe you can unlock the bootloader on lollipop.

Why do I need to wait for 5.0.2 root? Or unlock bootloader? I wasnt rooted and my zu bootloader was locked when I upgraded from 4.4.4 to 5.0.2 with Sony flash tool. All I needed was a ftf file with same region

I'm not sure if you can downgrade that way. I would try? Maybe not? If anything goes wrong you could always just flash stock again.
If you root and unlock bootloader you can move between android. I'm on 5.0.2 I can go back to kitkat anytime I want.
Has anyone downgraded from 5.0.2 to 4.4.4 yet? without having to root or unlock their bootloader. The reason I don't want to unlock my bootloader is because I accidentally erased my ta backup. That's why Im trying to get back to 4.4.4 so I can root and backup my ta again to unlock my bootloader. I just want to know if it is safe to downgrade my 6833 zu without root or unlocked bootloader
Thanks
Lollipop uses a different firmware so probably not. I didn't black up my TA .. I just went about unlocking it.
Try to flash a 4.4.4 ftf?
Yes but I want to back up my ta first before I unlock my bootloader because if I don't I'll lose the xreality keys and warranty. so it has different firmware so 5.0.2 won't be downgradable to 4.4.4? so you suggest I wait for a 5.0.2 root.
Sorry yes I wanted to to flash a stock 4.4.4 ftf with Sony flashtool
I figured I would give an update I was able to downgrade from 5.0.2 to 4.4.4 ftf with a locked bootloader without any problems

So someone who gets an Ota for lollipop can turn around and root their phone? The only reason you're rooted is because you downloaded a pre rooted rom.
So again lollipop is un rootable
So has anybody followed this guide?
Was it effective? I am reluctant to unlock my bootloader but on how my xzu sounds on my earphones, I am very eager to install V4A.
i am go to sony service center for downgrade the xperia z ultra from 5.0.2 to 4.4.4 but they said xperia z ultra chipset cannot support downgrade there any solution for downgrade bcoz my z ultra only get software by pc companion and flashtool and custom rom cannot work plz help me i flsah custom rom then device stuck on sony logo

You're in the wrong device section. This is the Z Ultra forum. Anyhow, I see that you have the ZL, so I'll make this short. Tell me your region, and I'll make you a 4.4.4 FTF.
EDIT: I'm assuming the C6506 is the American version of the ZL, so the only 4.4.4 file that's available is the one for Puerto Rico. I'm building it now, so I'll put a link to it here when it's done.

I don't prefer it cause i still have 10 months of my warranty for this phone and if my dad finds out that i mess with my phone he will be mad.. Yes i know babyish but.. And i also want my drm keys untouched..
