Hello. I bricked my devices while installing 4.3 fw (not official way) and than repaired using official Sony tool. It gave me 4.3 fw and I unlocked bootloader to install root and CWM. Now when I try to relock bl phone doesn't boot, works only with unlocked bl. How to relock device to restore TA partition from backup. Please provide step by step

After of a few hours of driver issues (adb windows 8 sony xperia z too) I have managed to make them all work.
I tried root without unlocking, no luck with that method
I tried unlocking with flashtool, It said "Done", my first doubt is how I can check my bootloader is unlocked?
After this I tried unlocking with the official way (sony, and I got bootloop,on sony animation logo)
So I had to flash the 10.3.A.0.423 (the one I had previously which I flashed it with flashtool)
Now I think pictures look a bit worse because I have unlocked the bootloader and I have lost the Bravia Engine but maybe its just me, how can I check if I have unlocked succesfully my phone? If I have unlocked it I have lost the BE? I tried to save it with no luck because I wasn't root
How can I succesfully install a recovery for installing another rom? all the tutorials aren't working for me neither the locked recovery cwm or the unlocked one..
Can someone link me to other tutorials?
The order is Root, Unlock, Recovery?
Flash doom kernel with fastboot,it has root and recovery.
If it's successfully flashed that means you have an unlocked bootloader.

In service menu (*#*#service#*#*) it will tell you "bootloader unlocked" ; if it's still locked you'll have "bootloader unlock allowed : yes"
If I do a backup for ta partition and unlock bootloader then flash Romaur'S rom. So will my camera work or after flashing the rom then do I have any option to restore ta partition and camera will work on unlocked bootloader

No it won't. There is also no need to unlock the boot loader to install that rom

Hey guys I have a rooted Xperia Sp(C5302). We know that our device is gonna get the 4.3 official update next month. My question is can we update to the official 4.3 even after having root or will it cause a problem.

As said above, root is no problem with PC Companion.
However, if you unlock the bootloader, no update whatsoever (PC Comp, OTA). After bootloader unlock only Flashtool /Emma will let you flash new ROM/updates.

Hi , so if i Relock the boot loader i will be able to use ota rite?
which is the safest method to Reload the Boot loader
I am using BL Unlocked Rooted Stock Rom ,
I think Sony stated on their unlock website that once you unlock the boot loader there's no way to relock. Check out unlockbootloader.sonymobile.com

If you backed up your DRM keys with TA-backup you should be able to relock if you didn't you are kinda screwed

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

You should flash stock ROM using flashtool, relock the bootloader, and then restore the TA partition

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

if i didnt make backup (because no one told me to ) i cant install 4.3 update from Sony if comes out ?
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?
Hello!
I currently backed up my TA Partition and DRM Keys using Backup_TA.bat, I now have an Unlocked Bootloader and also am running on a custom kernel ( FW .232 Lollipop ), my question is if I use the restore function on the Backup_TA.bat will that re-lock my bootloader?
Thanks alot!

Yes it will relock BUT
You need to be on an official firmware and rooted. And you must have the stock kernel. Then only you can restore. If your restore TA, it relocks bootloader. And custom kernels don't work on locked bootloader so you will end up in a bootloop if you are not using the stock kernel

Btw, do you another way of relocking the bootloader besides using Flashtool?
i try using restore in backup_TA but my bootloader its still unlocked
im on stock rom and kernel + root, in flashtool i dont have option to relock :/
Restoring TA is supposed to relock bootloader automatically aa far as I know :/
