I have a rooted Xperia S with unlocked bootloader, by following instructions on this thread.
Today I received a notification about OTA update to 6.1.A.2.45 (40MB in size) and I was wondering if I can apply this update without loosing root. I really did search for an answer on the forum before making this post and couldn't find anything specific for my phone, but what I did found only confused me more, which is to be expected since I am a noob. Apparently it worked for some users of Xperia Play with unlocked bootloader, but on the other hand some users of Xperia Arc S say that bootloader should be locked when making an OTA update.
I would really appreciate any help from more experienced members, I'm new in Android and don't want to start by bricking my phone.
Thank you for your time and effort.
Boom
better dont, you will end up with a bricked device. NEVER accept OTA updates if your bootloader is unlocked.
Don't update with PCC when you're unlocked.
Wow, that was fast! Thank you guys.
hi, did you find how to update?

i also have an open bootloader although not root, but i tried updating using the phone's OTA and PCC and neither worked. I promptly realized it might just be the open bootloader which is keeping me from updating, so how do we manually update? if you have any procedures will highly appreciate anyone..... thanks in advance

You can find your regions FW. (firmware) and download it, after that download and install flashtool, and flash the .ftf file via flashtool and that is it.
thanks for the quick reply

Im going to engage in a rather noobish conversation but i want to be completely sure before i proceed to install. my phone and my pc companion both find the update which is 6.1.a.2.45, which i assume is the one i need to find on .ftf. after downloading it from wherever i find it i just open the flash tool program and select it to start the installation? and again thank you

they have some firmwares there, but they seem to be full updates, because they are 300+mb while the update on my phone its only 40mb.
so should i just download the generic and proceed to flash?

Hmmm,
Slightly different scenario here.
I have a rooted xperia S with a locked bootloader and obviously want to preserve root.
Previous experience tells me that a PC update from SEUS does a full wipe of the phone and looses root however OTA updates usually preserve root. I was hoping somebody could clarify if this is still the case?
Thanks
if your bootloaders unlocked you cant update ota or via seus. it will just give an error about your device being modified

same question as you, i have a rogers xperia s with a stock uk rom, it's rooted but bootloader is still locked. Just want to make sure that i don't loose root, or the root method can still be applied after the update.

there is a rom somewhere in another forum i guess which already is updated and rooted. so you might want to just download that one and flash it. it has its own kernel and recovery.

I've not been on much recently at all so I could be wrong, but I'm sure it's been said that you can flash ROM such as the linked one when bootloader is locked and perhaps the pre-rooted one too. May need to search the thread.
Nothing out there that allows me to root my Xperia S on ICS without wiping my data though I think. One can wait... or dream. :[

Yeah having too wipe at this point is a bummer. If I'm going to wipe my phone ill wait for the ability to unlock my locked bootloader.
Problem with that is I will most likely have a new phone by then.

Hi people. This is my 3rd android device. Two samsung products, and now the Z ultra.
So I have no idea what people are talking about... I'm used to ODIN... so is flashtool a similar piece of software?
My xperia Z hasn't arrived yet, Im just trying to get my head around sony and the way their devices are run..
So.. questions...
1. Backup your TA partition (I read that this has important info that I don't want to loose... Do i do this with flashtool? Do i also reflash this partition at a later date?)
2. Unlock your bootloader (Why are some people not unlocking bootloader... Do I understand correctly that some features will stop working... like x-reality?? If so, can't they just be reactivated with a custom ROM?)
3. I see there is a recovery for locked bootloaders... (can you still flash kernel's custom ROM's zips using CWM with a locked bootloader?)
Ive spent 3 days looking on the threads here, but I think because of my previous devices I have a preconceived idea of what i should be doing.. I'm confused.

Now everyone knows you're a n00b!
First of all, the minus of unlocking bootloader is losing your DRM keys. To do this, sony has provided us an official way through their website (just google it). Or you can do this via flashtool too. After unlocking, you will lose xreality engine and won't get FW update from sony anymore through official means (pcc or ota, but you can always flash). Some says trackID will be lost, too, but hey, who use it anyway?
The plus is, you entered godmode for flashing anything into your phone.
Unlocked bootloader can be relocked through flashtool, but relocked is not the same as locked, because xreality is still lost, cmiiw. To restore to original locked state, use backupTA (search thread in xda) BEFORE unlocking bootloader. And backupTA needs root, so we need root w/o unlock bootloader first (already plenty in other threads).
And yeah, what a maze this is.

Ok thanks, that confirmed what i thought about bootloader..
Can you still flash VIA CWM with a locked bootloader?
otherwise as i understand it...
1) root device
2) backup TA parition
3) unlock bootloader
4) flash ROM/kernel/etc
5) reflash TA partition.
done... custom ROM with x-reality support?

Well it's harder to make, apparently. Currently even custom recovery for locked bootloader is not finished yet. Check the development section. And flashing things that normally isn't allowed on locked does have limitations, check in other xperia devices threads.

Actually on firmware .510 with unlocked bootloader and I still have Xreality. Making your Ta backup is mainly to be able to restore your device in case of softbrick or restore your phone to stock.

I am looking at getting the phone too. From what I understand is when your bootloader is locked, it will only load signed boot partitions. So any modification to the boot partition outside of the official stock kernel will not boot when locked. So installing any custom kernel (OC/UV/etc) with stock rom needs unlocked bootloader, or installing CM (which has it's own kernel anyway). So best is getting custom roms (only modified system) with stock kernel.
Also like already said, unlocked bootloader means no updates from Sony. I would backup TA at all costs anyway.
I doubt stock kernel supports kexec, but I guess you can hack the system init process to load different ramdisks. Which is why I guess they are having trouble with locked bootloaders with recovery ramdisks in the dev forum.
I am waiting for the C6806. Here are my plans:
1. Root using vroot (hope it doesn't infect TA with something ;o)
2. Backup TA Partition
3. Unlock
4. Deal with loss of DRM
5. Install whatever ROM/kernel for daily usage
6. (maybe make official TWRP)
7. Get official updates by restoring TA partition, stock kernel if necessary
or...
1. Root using vroot
2. Backup TA Paritition
3. Stick with stock kernel
4. Help with getting locked 2nd ramdisk working with stock init
5. Is the stock ROM awesome enough? (Not sure since we don't have 4.3 )
Also hoping info comes out about ATT bootloader soon on Note 3.
LTE phone is out by 9/25 I am thinking with US warranty support. (C6806)

$100.... it's sounds good? Okay from my experience I bought my XperiaZ from Australian Telco before and it said Bootloader unlock allowed:No
but when I flashed official generic ftf using flashtool. It's said Bootloader Unlock allowed:Yes. So if you can take a risk try it(do it by your own! and don't forget to back up!)... you might try to do that. Luckly my XperiaZ2 is bootloader allowed one. Hope I have a chance to get 100bucks

This is very dangrous, this depends on the contents of the FTF and i wouldent recoment this at al
Have you tried flashing the German DE generic FTF, i think it has stuff for the TA partition
This may do your job
I still dont recomend, do this at your own will if you know how to unbrick a device
Although i would try it but only because i know how to unbrick a xperia (lol this part usualy takes a while)

I noticed him that it must be done by his own.... But he asks us to is there are anyway to do that? so I just posted the way I did.
I am not recommending him to do that.... I just simply answered his question. Always flash ftf w/o TA and partition.
It is recommended everywhere and If once he started to searching about flash tool it is warned by everyone.
You can't back up TA partition w/o root. So I don't think there is any way to get XperiaZ2 to back to completely stock.
(Although i would try it but only because ←What does it mean? It doesn't make sense for me.)
Well, I tried to flash the stock FTF.. same version as my devices. It errored.. and I am now bricked.
You can't modify an FTF and flash it to a bootloader locked device, modifying it will break Sony's signature verification
I'm guessing there's no way to unbrick?

How i unbrick my devices usualy (if they are locked bootloader)
Pt1
Unplug device totaly
Hold power
Hold volume up
Wait for it to buzz 3 times in a row
(rubber bands usualy help)
(ensure battery isnt killed from doing this (low charge)
(aka dont leave rubber bands for several hours)
Pt2
Download and install sony PC companion
Go to support
Go to repair device

You'll need to find Sony's signing key then. Good luck with that
Aww.... We warned you.... it must be done by your own and not recommended. Try SEUS.... (Not sure if it works for yours....
Everything what you've done with flashtool will be avoid your warranty..... I think when you downloaded flashtool they warned you again....
As EnviousData warned you too.... even I did not recommended to do that.... dear....
Ok, I managed to unbrick.. back to bootloader unlock allowed: No
Still.. If you guys have any ideas how to root.. $100.

Honestly i say keep your $$$ and wait for a exploit or root method of sorts
Me and my FTF will be a while and Z2 Development has started very slow and may be a while before anything of the sorts comes avaliable
I suggest if you realy want to root try exchanging your device for an unlocked one (or unlockable :/)

hi,
I started this thread:

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

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

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.

Its takes a while but felt more comfortable than just some random dl.
here is the .314 i created.

You can update via flashtool without looking data. Flash ftf file and check system only and uncheck wipe.

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
@[w] Hey m8, Here's a step by step guide with videos from xperiafirmware hope it helps. BTW did you re-lock your bootloader?

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:
Hey Guys,
So I just bought a Z2 with Android 4.4.4, and after a lot of reading I understood that there is no "one click" rooting option for it and that I have to downgrade first and then flash a rooted ROM.
The thing is I checked all the the current threads and they are somewhat very hard to follow through and a little bit made to advanced users
Topics like: http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155
So sometimes midway they skip a step or dont explain how did they reach there (specially after step 9 in the above tutorial)
I know I am asking too much, but will someone walk me through how to root my locked boot loader phone ?
FW: 23.0.1.a0.167
Thank you very much
There are 2 ways to root
Safe way which is this way which includes downgrading and having to reset your device twice
Or the easy way which is unlocking your bootloader (losing your TA and DRM Dependant features) flashing a custom kernel + recovery
You cant root at all without losing data
Hi mate
I suggest you to try this method first
http://forum.xda-developers.com/crossdevice-dev/sony/giefroot-rooting-tool-cve-2014-4322-t3011598
It doesn't work for me and if it doesn't work for you too we can talk to the author to support our devices
with my best regards

Hey Mate , Thank you for your reply
I have tried it but it didnt work, it says my "phone isnt vunerable", I have sent to author waiting his reply.
If you have any other pointers for me that would be great !

I have also the same error now we are sure that our devices are not supported yet I think he needs some informations about the kernel.
I sent him message and I got a reply but he thought that I have 4.4.2.
He told me that he is busy.
I sent another message and I'm waiting his reply.

Then How to do it even with losing data, but not losing the original FTF ?
Again sorry for being a noob

Its not too complicated, but im sure its 100% safe. The step only required downgrade and then install the pre-rooted rom. If you know how to flash with flashtool, then this is not a big problem. Before you begin, please make sure you understand each step that you gonna do. This is how actually i do.
1. Download all files required(ftf, rooting tools, prf creator, recovery, etc)
2. Make the pre-rooted rom first.(i just skip that step 11)
3. Flash the stock .314
4. Root & recovery it.
5. Insert that pre-rooted ftf that i made early, in my case i also use a stock rom .167
6. Reboot and finish.
I've rooted Xperia Z before and I'm sure it was much easier. I'd like to root my Z2 but it's much more complicated. I mean I know how to use flash tools, but I'm a bit lost when it comes to drm keys. Is it possible to root and unroot if needed so Sony won't know if anything goes wrong ? Does your method involve drm backup?

This method doesnt require to unlock bootloader, its safe. Backup drm key can only be done after u root your device.

Yes root doesn't harm your DRM keys only unlocking the bootloader will do that and here are so manybthreads howto get root on locked bootloader, just search before posting and read the rules !!

Yes rooting doesn't Unlock your bootloader so no loss of DRM keys. Its theoretically impossible to hard brick a locked boot loader Z2.
