You will have to download the Sony Flash Tool and update. PC Companion does not allow update for unlocked bootloader.

Yes, you can use that Flashtool too. But you'll need to find the FTF file to flash.
You can flash even though you're on custom kernel. But you'll have to reflash the custom kernel after the update.

No, it will not automatically find the firmware for your region. You will have to find it yourself, either from XDA or the function within Flashtool (Devices > Check Update). Using the Sony Flash Tool is easier.

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.
Thanks

Dude!!! NO IT'S NOT ROOTED
P.s I've done it 5 times already and my firmware was rooted ( Stock) and on a custom kernel
By just relocking my BL and update it via SEUS!

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
http://forum.xda-developers.com/showthread.php?t=1752864&highlight=6+1+a+0+452+generic+uk
http://www.multiupload.hk/Z97BXEH24E
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?
Thanks
Mav
This one and relock the BL.

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] upgrading firmware but unlocked bootloader

hi,
I started this thread:
http://forum.xda-developers.com/xperia-z2/help/upgrading-55-to-314-t2860394
but ran into an issue. Since I didn't get any updates on that thread, I thought I would make a post dedicated to the problem I'm running into.
basically while attempting to upgrade to .314 using PC Companion I get
The phone tablet contains modified software that cannot be updated
Sony Updated Engine failure (error 2003)
Click to expand...
Click to collapse
with some research it appears that this is because i unlocked my bootloader.
Questions:
is my conclusion correct? or is this because of something else?
if correct, what is the recommended course of action here? relock bootloader and update using companion PC or decrypt FTF files and flash using flashtool?
If i relock bootloader using flashtool, will it wipe my phone data?
I've found the firmware files on my computer (C:\ProgramData\Sony Mobile\Update Engine\db\13740270\blob_fs) If i decrypt these with flashtool and use them to update firmware, will it wipe my data?
Thanks
You can update via flashtool without looking data. Flash ftf file and check system only and uncheck wipe. Re- locking bootloader will wipe your phone. Your assumption is correct m8. You can't update your phone with pc companion because of your unlocked bootloader. Happy flashing m8

Hey! thanks for the help on this subject.
I wonder where I can find official tft for sony z2 (314). I'm in exact same position as [w]. Want to upgrade the software (stock) but I already unlockd bootloader and flashed stock kernel with recovery. Sony software says that can update the phone, but I don't want to download som strange tft. Want the oficial tft image or some goo source.
Thanks again
hope you have a nice day

I'm also kinda paranoid so I just created my own FTF from official Sony update via Sony PC Companion using these instructions.
http://talk.sonymobile.com/t5/Xperi...eria/This-is-how-to-create-an-FTF/td-p/228703
Its takes a while but felt more comfortable than just some random dl.
here is the .314 i created.

So i'm a little paranoid, can you explain like i'm 5?
attached is a screenshot of the flashtool interface
What do i want to check and what do i want to leve unchecked?
do you mean that all the check boxes under WIPE should be empty
and the only checkbox under EXCLUDE that should be checked is SYSTEM?
thanks

sweet. upgraded and rooted using "Easy Root Tool" (was super easy!) :good:
for others discovering this post i've attached a screenshot of what my flashmode tool looked like:
basically under WIPE make sure DATA is unchecked. you will notice that userdata.sin disappears from content list
under exclude make sure nothing is checked.
win.
@[w] Hey m8, glad to see everything went ok Now you are all set to go and mod to your heart's content:highfive: Thanks for posting the screen shot and explanation as a reference for noobs/Sh*tsung refugees to see how the Flashtool screen should look during upgrading. Once again thanks for that:victory:

[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.

No OTA on Unlocked Bootloader + Root ??

A noob question I guess, but everytime I search for this answer I get different results. My D6503 is rooted using KingRoot and bootloader is unlocked following the official sony method. Will that prevent me getting the latest Marshmallow update via PC Companion?
Yes. You can't get OTA or PC Companion update on unlocked bootloader.
Grab a FTF and flash via Flashtool. As you are on unlocked bootloader, you can root it quite easily using Advanced Kernel.. Look for it on development section.
