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.

Hi guys,
Just realized there is a new update. I am on rooted .290 model C6802,
Here are my few questions:
1. Do i need to update it from Sony Pc Companion ? As on rooted fw there is no notification for any updates.
2. Do i get to keep root ?
3. Will I still have an unlocked bootloader?
4. Will I still have a stock kernel ?
5. How do i update it to a clean stock rom will every thing 'untouched' ? Wanna check a few things and then root later.
6. Any improvement in this fw ?
7. how do i keep track of fw update as my ultra doesnt deliver me any notification ?
1. You have to update it through PC Companion or SUS..
2. No doubt your root will be lost..
3. To keep the root you've to first update then unlock the Bootloader of your device..which will void your warranty unless you take a TA backup and then unlock..
4. To root on your lock Bootloader you've to wait for a while..
Revert back if you need anymore info..
Hit Thanks if I helped you..

1. I've not see anyone with an ota update, I think they have all been PCC or flashing a FTF
2. The FTF kills root, not sure about PCC. Root is easy to get back with a unlocked bootloader http://forum.xda-developers.com/showthread.php?t=2630781
3. Wont touch the BL state
4. Yes
5. Um... just flash the FTF or via PCC - make a nandroid backup beforehand of cause
6. There is a thread about this in grneral
7. Plug in the ultra to a PC, some of the updates have come as OTA, but will normally fail on a rooted device
Thank you for the reply
The update doesnt work from the pc companion on rooted devices.

That leaves two causes, unroot and flash via PCC or flash the FTF from flashtool. Plenty of ways to get root back if you have an unlocked bootloader now
FTFs are here http://forum.xda-developers.com/showthread.php?t=2453921
For now I am trying to decrypt the file I downloaded from pcc. Hope I can make a ftf then.

Lol! But C6833 is an LTE variant. I think it will drain battery. I guess c6802 should work better on its dedicated stock fw.
Anyways u knw better.
btw to unroot you need a locked bootloader. To avoid bootloops a stock kernel is required rt ? I am on fw. 290 but cant find the stock kernel anywhere.

Judging by the posts I've read and from my own experience, it appears if your tablet has been rooted or if its boot loader has been unlocked, OTA updates will fail.
You could relock bootloader if You would have TA backup. Without this I think it is not possible

No, I don't have a TA backup, as I bought this second hand. It is an inherited problem !
I guess I will need to go the whole way with the tablet, and try and load KitKat 4.4.2 from an image.
I have a large learning curve to climb.
Does Google Play work on images that are uploaded to the SPG311 tablet ? What other limitations are there from using a custom ROM (even if it is a Stock ROM) ?

I believe you can simply relock your bootloader using Flashtool by following these steps:
1. Make sure you're using the latest version of flashtool
2. In flashtool click the button that says 'BLU'
3. When it asks you to, connect the tablet in flashmode (hold the volume down button while connecting it)
4. Click on 'Relock' on the prompt window that will open
5. Follow whatever instructions flashtool gives you and disconnect the device after its done
But please verify this by searching online before trying it out because I'm not an expert and I did this on a Xperia Z Ultra succesfully but not on the Tablet Z. I wouldn't want to be responsible for messing up your tablet!
Once you do relock the bootloader OTA updates will be allowed.

I was able to successfully downgrade to a 4.1.2 image, root, then upgrade to a 4.4.2 10.5.A.0.230 STOCK ROM using the instructions at
[STOCK ROM] [Root] [FTF] 4.4.2 Kitkat Xperia Tablet Z SGP311 10.5.A.0.230 VMo UK IE. Very good instructions, and easy to follow.
Now my SGP311 is on 4.4.2, rooted, and I have not had any problems at all with Google Play. I don't think I have found any limitations.
Hope this helps.
Does towelroot root the xperia z2 with .314 firmware ? And it roots it with the bootloader locked right? And if yes can i update the stock firmware via ota or pc companion as soon as a new stock firmware is available? Thanks !
@nicojapanese Hi m8, yeah Towelroot will root .314 Firmware (I used it with my locked Bootloader). It may update over OTA but no guarantee. You can update via Pc companion by repairing your phone (you will loose root though) then re- rooting or you can flash a FTF via Flash tool. You can find loads of usefull info and links regarding Bootloaders, Flashtool, rooting and recoveries etc here. Hope this helps ya a bit m8:good:

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 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

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)

You will likely be waiting some time, because it's possible to downgrade and flash pre-rooted zip or to OTA certain FW's maintaining root, I don't see devs putting a lot of effort into finding an exploit. That said best hope is probably an exploit being found for Z3 which is transferable to Z2, but as I say you may be waiting some time.

You don't need, you can flash back an original ftf anytime or repair with Sony PC Companion. We are talking locked bootloadr, so until you don't unlock it, you have warranty.
But if you already have root on prev. firmware, you should install DualRecovery and boot into TWRP and you can backup your system there.
