Heyy guys I have a XperiaSP which have unlocked bootloader and unrooted phone (just unrooted it a while ago). I would REALLY like to update my phone because there's too many bug here on Xperia SP. However, when the phone was still rooted I tried to update and it failed. Now after unroot I was going to update but then the fact that I unlocked the bootloader I am really worried about wiping/bricking the phone through OTA update. Any help pls?
P.S - My phone is barely Unlocked. It is nearly as stock and no custom recovery nor root is installed.:laugh:
Edit : By the way, is the Xperia SP really got Wi-Fi issues? My iPod got full signal on home's wifi and my SP got barely 1-2..
hmmm

did u try using PC companion? Is It ok there?
Or else I think you know that Sony's 4.3 update is on the corner. that may will solve your issue

Ahh yeah gonna try that ASAP. but I just forgot to mention that my primary laptop is now on service center (Got a bit problem there) so I can't really update my SP through that.
I tried updating just now through OTA. After the reboot a popup message appeared :
"Could not install new software version. Try again."
Is that because of my unlocked bootloader? Cos I unrooted my phone completely through SuperSU.
If so how to relock the bootloader??
If you want to relock the bootloader just use FlashTool. In your case because you don't have any custom Firmware on your phone this should be quite easy.
But I always thought when updating with having root access you can update but lose root. Maybe it didn't work (the update) because of a complete diffenent reason. Did you try it a second time?

When I got my laptop back, I'm definitely going to relock the bootloader. But if I do something wrong, will it hard brick or something? (sorry for my parranoidness) and relocking is not much difference from unlocking right?
I tried installing the software update the second time. Unlocked BL, fully unrooted (No Super SU). Still fails gonna try at PCCompanion

I'm on my stock ROM now (Default Sony ROM right? But I've updated it before, does it count as stock?)
What's TA partition?
Sorry for noob Qs
I never do this before.So can I update my phone via pc companion via unlocked bootloader?On stock rom without root and recovery?

If you didn't flash anything on your device you can relock your bootloader without any problems. If you had a custom recovery, kernel or ROM and you relock your bootloader while having this custom recovery, kernel or ROM this should brick your phone (I think this could even be a hard brick) but if everything is stock (like I already said) there shouldn't be any problems with relocking
TA partition contains the working bravia engine (2) which gets lost if you unlock bootloader. If you had made a backup of the TA partition you could restore this and get the bravia engine back

Yes, you'll be able to get the 4.3 update without the TA partition. But, as everyone else here said, make sure you're on a stock ROM, with a locked bootloader.
Locked bootloader ----> You can use PC Companion or Flashtool to update your phone
Unlocked bootloader ------> Flashtool only
Also, don't try to update your phone via OTA while having your bootlader unlocked, because it will brick your device.

My original Stock Rom had been flashed to CM 10, but now I have flashed it back to stock rom that I tried to search online from this site. Is it counted as original stock rom or not? My phone is unlocked bootloader, and I got ota update but cannot install, I don't know why; maybe it has been changed or maybe of unlock bootloader?

Hi there!
I've unlocked using flashtool, installed CWM Recovery and rooted using the recovery-only root.
Now, I need to return the phone to as stock as possible - certainly removing root, but relocking the bootloader would be a good secondary objective.
My current plan is to use the flashtool to relock the bootloader, then use the PC software to repair the phone. Will this work?
Thanks for your help
Edit: I've searched the forums but can't find an answer, including in the starting thread - please link to a relevant portion instead of the whole thing if possible
Further edit: There's no 'relock' option in the flashtool - huh?

As of now there is no option to relock the bootloader. You can unroot the phone by simply performing a repair system command in Sony PC Companion or flashing a stock rom. This has been explained in every single rooting or custom MOD thread.
Ya you are right. Relock bootloader using flashtool and repair or flash a ftf from flashtool.
And IIRC in the beta version of flashtool u will find option to relock under BLU. And btw u won't get back DRM keys and no Bravia engine.

I don't see the option to relock anywhere - perhaps as I did the unlock on another PC?
If you can't get it to work with PC Companion use SUS (Sony Update Service which you can download from Sony's website) http://www.sonymobile.com/gb/tools/update-service/ --> for UK

Thanks - I expected there to be a separate button for relocking - whoops!
I've flashed the stock ROM and that's gotten rid of the root. It also says that the bootloader can be unlocked, so that seems all perfect as far as I'm concerned. Thanks for your help, ladies and gentlemen.
Hi,
I have the latest stable CM installed on my XZ, but I miss the Sony ROM, so I thought I'd revert back, though I'm a little unsure about how to so it. Before unlocking the boot loader and installing CM, I rooted the phone and made a backup. My question is;
Can I revert back by doing this:
1. Booting into flashmode, wiping the cache
2. Choose to reinstall my back-up file
3. Relock boot loader in flashtool (if necessary, it was locked when I backed up)
4. "Repair phone" in Sony update service
And then be back to how it was before?
Seek and you shall find. Or look at the stickies!

Thank you!
But that doesn't really answer my question(s), and as they were very specific in nature, a simple "yes" would be sufficient, or a "no"m, accompanied by the aforementioned links. ^^
I'm new at this, so that post has a lot of information... That's why I asked in a separate post.
You can just flash stock rom with flashtool. You don't need to relock unless u backed up your ta partition and you want to have bravia engine and updates.

Since it's so hard to get a reply regarding my original post, I'll ask it like this;
Can I flash an official sony rom (.ftf) over my CM10.2? If so, can I just relock the bootloader through flashtool as well to get back BE2?
The key to get BE 2 working again and have fully restored DRM keys is to restore the backup of the TA partition that you should have taken before unlocking the bootloader. Flashing stock FTF and just relocking bootloader won't do the job
Neither will a CWM restore.
Sent from my C6603 using xda app-developers app
I made the backup in cwm before I unlocked the bootloader, is that not usable to get it back? Is there any other way?
Unfortunately, CWM doesn't backup Trim Area (TA).In your case it seems Sony DRM keys are lost forever :thumbdown:
Sent from my C6603 using xda app-developers app
I see. Oh well. BTW, I unlocked the boot loader once before, but then I relocked it without making any changes. Did I lose BE then, or not before I installed CM? And what other than BE will I have lost? :/

Yes you loosed it. If you unlock you booloader you loose the keys. That is the reason why you have to make a TA backup before unlocking.
Your warranty you loose also but I think you should know that
Dear all,
I have one more noob question again.
I was use a tool name Backup-TA-9.8 to backup my Xperia Z1 DRM. If I unlock it boot loader I know that the camera will not work. But if I relock it bootloader and restore my DRM. Dose the camera will work well again?

Small question, wouldn't it be possible to unlock, root (by pushing su binaries in a custom recovery and restoring stock recovery), and relock? No reason it wouldn't work imo, and I find this procedure faster than doing the downgrade, root, recovery, upgrade method

yes, but when you unlock you void your warranty, so unless you are planning on keeping an unlocked bootloader I reckon the extra minute it takes to downgrade etc... is worth it to keep your warranty
Also,
There is no such thing as a "stock recovery" on Xperia devices.
Also,
there is no need to install a recovery on the downgrade method if you do not want to.

No warranty here anyway.
I remember OTA-upgrading an Xperia Z, and that simply flashed a zip package in recovery. Why would there be no stock recovery?
And you need to install a custom recovery to do the upgrade, either that or copy files while the system is running, and I'm not sure how the latter would work without the system crashing at some point.

No.
Xperia devices have never come with a stock recovery accessible for the user.
Upgrading OTA means you do not flash it in recovery, you download the files Over The Air and then the phone upgrades itself.
No official upgrades are done in recovery, only custom kernels, custom roms or custom updates are flashed in custom recoveries

I know what OTA means, on previous devices with stock recovery, it simply drops you into recovery and does the flashing itself without the user ever having to touch anything. Same goes for wiping user data, it's done in recovery.
Whether the recovery is accessible to the user or not is another thing, and I didn't know about it, so thanks for that.

1stly i have 4.4.2 (.757) running on my z1 and i downgraded to .534 and i rooted the device by vroot and backed up the DRM keys successfully.. and then i flashed to .290 and unlocked the bootloader by flashtool and then downgraded to .534 and then installed the dual recovery and then flashed using the flashable recovery using recovery and then i found that camera is not working properly.. camera is opening and when i press the shutter butter its trying to focus the area and after focusing it freezes and doesn't shutter... so this is my problem... please help...
So much fail.
Do not use vroot, it sends your imei number to an ip address in China.
Also, unlocking your bootloader on 4.2 will break your camera, it clearly says so on the Sony official site about unlocking your bootloader.
Now, the solution.
Restore your ta partition.
Use pccompanion to update to the latest firmware
Unlock your bootloader again
Flash a custom kernel of your choice
Install super user app of your choice

I have to ask
Why are you unlocking your bootloader? What have you done it for? You do not get a recovery mode just by unlocking the boot, you have to flash a custom kernel with recovery in it
You either do all the downgrading and install dual recovery if you have a locked bootloader
OR
You unlock your bootloader, flash a custom kernel with recovery and install super user app
there is no need for both approaches and that's why you are getting problems

Why did you unlock the bootloader? What did you want to do with it?
You can not install a recovery without a custom kernel, xperia devices have no recovery partition, it can only be installed by pushing the ramdisks to the system partition or by flashing a custom kernel.
Please follow the advice I gave several posts ago.... that is your solution.
Then spend some time reading up on xperia device flashing.
1) Xperia devices have no factory recovery or recovery partition
2) Unlocking the bootloader is the fastest and easiest method to root and get recovery (If you are allowed to do it)
3) If you cannot or do not want to unlock the bootloader, then go through the downgrade, root, dual recovery process...

Greg said fifteen times - follow his guide for here.
Yoy can't flash custom kernel especially not fastboot custom kernel on locked bootloader.
Whole purpose of unlocking bootloader is to flash custom kernel.
You are confused with all this informations, I would recommend that you read few things here on XDA to understand terms and other things.
You could seriously damage your device with just one wrong step.

I bought it new from Sony with Kitkat on it in middle east -Dubai
The issue is being sorted via PM with me.
However, this is a synopsis.
The OP unlocked the bootloader on 4.4 - Camera works.
Then, instead of just flashing a custom kernel to gain root, the OP followed a guide for a locked bootloader to gain root. Once they downgraded to 4.2 the camera broke.
In order to fix this the solution is
1) Relock the bootloader (by restoring the TA partition if a TA backup was made, in this case not, or by using flashtool)
2) Use pccompanion to upgrade to latest FW
3) Re-unlock the bootloader by the official method (Or flashtool, if it was re-locked with flashtool)
4) Flash a stock based custom kernel
5) Install SuperSU from the play store.
