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.

Sounds like a good idea, I do agree that it gets crowded and the real good stuff coming out (CM9) are being pushed down the drain.
hmm, in HTCMania i have a thread with all Firmware + ROOT listed, maybe a someone can do that here
procedures ? flash pre-root img then firmware ?
does the unrooted version has the blue battery percent mod and quickpanel?
if not, is it possible to make ftf file with these mods without rooting, as I can't root my device because the bootloader is not unlockable
i have unlocked bootloader and rooted
but i cannot get update from sony,
how can i rooted the LT26i with online update enable ?
can i flash rooted firmware and then relocked the machine
and go for online update to 73 with root still in the machine ?
srsly, do you read the guides? its in RED and HUGE! IF YOU UNLOCK BOOTLAODER YOU CANT UPDATE VIA OTA - PCC - SEUS
I know....,
so, what I'm planning to do is to unlock bootloader and root it
then relock bootloader again and go for OTA update.....
but the problem is will root remain when I update or relock bootloader again ?

Either way, rooted or not, you can always relock the bootloader. Once locked, you may proceed with any official firmware update using SEUS (not pc companion, as you can't download 73 firmware with it at the moment).

Need help to relock BL, Install stock rom & Kernel as Yellow tint issue

Hi All,
Recently got an xperia s, and to be honest been having a few issues with it, i.e memory probs connecting to pc, and yellow tint on screen.
Stupidly prior to checking everything as always I jumped and unlocked the BL, and installed a custom kernel and rom, XSX and K10 ICS.
I had also prior to this updated to ICS via sony. Problem is now I realised that it has the yellow tint at the bottom of the screen so prior to sending it back to sony I want to relock BL and install stock ICS again and stock kernel.
Please can someone show me a link to this I'm in UK and have a factory unlocked version, I have tried to search but I am confused to which one I need, I also cannot find any kernel.
Finally they are all FTF files and I need to be in Flashmode to use these, unfortunately for some reason my phone will not stay in flashmode green light for more than a few minutes and it just boots up so I dont want to start flashing only for it to stop in between and brick my phone any ideas?.
BTW I managed to install fastboot drivers in windows 8 I know some people had problems in windows 7 & 8, I found a solution if anyone needs
Thanks
Mav.
So simple ^^
1st You need to relock your BL via Flashtool by using This http://j.mp/xps_relock
From here http://forum.xda-developers.com/showthread.php?t=1527159
And when it's done, just update your phone normally via SEUS (Sony Update Service)

Thanks jvsykes,
I thought that you had to first have a stock kernel installed prior to relocking your BL otherwise it would brick your phone, I read it somewhere, I would prefer to have a stock kernel and stock firmware then relock the BL, then possibly put it through SEUS to make sure everything is right.
you dont need to relock the BL for yellow tint issue, the custom roms have nothing to do with it, ive sent my phone back twice unlocked bl and custom fw and its been fixed twice without question

Aha,Well just Flash Stock Firmware via Flashtool [ http://depositfiles.com/files/130eommqj ] [FIRMWARE][6.1.A.0.452] Nordic combined
From here http://forum.xda-developers.com/showthread.php?t=1599303
It will replace your Rom and kernel,after that you can Relock your BL ..
Thanks guys, I really appreciate your help.
Isnt the firmware link rooted?, if so unlocking BL more thank likely will brick it so i've read, also when I go to download it asks for a mob number dont really fancy that?
Dont really want to risk sending away if BL is locked anarchyuk, although i know by right they should fix it.

But its not a UK stock, I've managed to use flashtool to install 6.1.a.0.453, but of course thats not officlally our yet so if i sent it in they would know at some point its been rooted to install this rom.
just cant find UK unrooted official 6.1.a.0.452 in FTF or ZIP/RAR format.
Ok just found this

its a uk generic [6.0.A.3.75]
I can flash this, then relock BL, then use SEUS to update to stock 6.1.A.4.52
Does that seem correct?, or will I have probs?
Also the file I would be using to relock BL is called X10_V1_BLRelock.ftf is this correct?

Reflash the stock firmware then the bootloader lock. Also look in development section for Xperia s Relock. It is called that not the X10 one.

regarding update .136

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.
I tried the depository but cant find one for C6802.

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.

[Q] Rooting with locked bootloader and software updates

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:
OTA/Usb updates will fail verifacation if rooted
Unroot and uninstall all mods and it should work, if not flash a FTF using flashtool

Worse case if you root is you'll need to install L as an ftf via flashtool, so if you want root I'd go ahead.

[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

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.
