Hey guys i know there is probably an answer in here somewhere but ihave looked everywhere and tried all possible options to get this working. After my pc companion nagging at me to upgrade i bit the bullet and upgraded to JB 4.3 10.4.B.0.569
Afterwards i then found out that it had relocked bootloader and unrooted my phone..
So i went through the sony normal way of unlocked bootloader first of all... this is where i've hit a snag.. first time the Command promp told me it had failed then itried again with my KEY and it said DONE.... now my phone was stuck in a terrifying bootloop. So i then flashed 4.3 firmware using flashtools, and repaired my phone through sony center.... again.. tried to unlock bootloader and was stuck in boot loop. I have re flashed about 4 times and tried to unlock 4 times... still getting boot loops....
Any one care to shed some light on this?
Many thanks
Chris

Is bootloader unlock allowed?
Have you tried relocking it again using flashtool?

Hey
I was playing around with 4.3 all last night and managed to get root on my Z with locked BL,
Here is how I did it..
(Locked bootloader, skip unlocking if already unlocked)
- Flash the .67 firmware via flashtool
- Root 4.2 as you would have
- Unlock your bootloader and Backup the TA partition to relock this without losing any DRM keys
- Using flashtool flash the new firmware .569 (4.3)
- Then flash Doomlords advanced stock kernel
- Boot 4.3 and power down
- Using the recover installed with the kernel flash a superSU.zip from somewhere around here.
- Reboot and you now should have root
[Locked bl]
- Reflash ONLY just .569 kernel from the FTF
- Power on and Restore your TA partition to relock your boot loader and return everything back to normal..but with some root
As for your bootloader not unlocking properly i would first check to see if an unlock is allowed
when i try to flash 4.2 67 firmware..i just got bootloop..please someone help me..what have i done wrong..i still in LB..
Wipe data when flashing.

Just unlock your bootloader through Flashtool when on newest firmware, flash advanced stock kernel, root,flash back stock kernel and re-lock your bootloader. should be working for you, and it wont take that much time :good::good:

If the warranty and features such as Bravia Engine 2 are important to anyone, please don't just follow this. Your DRM keys that allow BE2 to work and your warranty will be permanently lost.
Follow the earlier post in this thread and downgrade, root and backup your TA partition BEFORE unlocking the bootloader.

Fix the phone with flashtool? Means flash the firmware ftf file?
Yes this is i think the best to do now.
But do it if you are sure.
It can maybe brick you device

Use flashtool, it won't brick your device if you don't do it on purpose. He has a boot loop on the animation so he is not hard bricked. If he can access flash mode then he can restore his device. He just needs to flash the ftf that is for his device
Never update your unlocked boot loader phone with PC companion and over the air as it will brick your device. Flash new Sony updates using flashtool
With the official flashtool they want to prupose update for unlocked.
It still on beta but sound promising

Hi,
I have Sony Xperia t2 ultra dual D5322 with android 5.1.
Once I unlock the bootloader,
If I flash stock rom (ftf)via flash tool,whether my bootloader still in unlocked mode or in locked mode??
if it's in unlock mode, installing the custom recovery and flashing superSU package will lead BOOTLOOP or not
I am asking you only because I install the TWRP and update superSU in locked mode.which results in system hang on bootlogo.
Is custom recovery can change the file system permission from readonly to readwrite if yes how??
Please answer me,
thank you.
I rooted my phone,installed recovery and i installed custom rom,but that rom doesn't work properly (The phone is just restarting all the time).And everything i can do is to put my mobilephone to flash mode,then Flashboot recognize it,but i don't know what to do then(i tried to flash some kernels but the problem is in rom),can anyone please help me?
Is your bootloader unlocked? You need an unlocked bootloader to flash a non-stock based custom roms. Since you can connect it to flashmode, download flash tools and flash back a stock rom. You can unlock your bootloader if you want flash flash a custom ROM.

The only way is, after Relock Bootlader, root your phone on Locked Bootlader and install recovery and then when you are on Locked Bootlader with Recovery you will use the Recovery to backup what you need.
Hi everybody,
after reading about how to upgrade & root the Xperia SP on the 4.3 firmware I followed the guides to get everything set up.
Now, after being nearly there I'm stuck with a black booting screen.
Here follow the steps I did undertake so far, any help to resolve my issue would be very welcome.
I started with firmware 12.0.A.2.245 rooted with Doomlords method (flash old kernel, root, flash .245 kernel again)
1 backup contacts/messages etc
2 do TA partition Backup with Backup-TA
3 update firmware using PC-Companion
4 unlock bootloader with official sony guide
5 fastboot flash cwm / superSU
---> everything worked fine so far (phone was operational), now I wanted to get the screen mirroring working - meaning the bravia engine. So I went for
6 Backup-TA check backup integrity with dry restore
7 Backup-TA restore TA partition
last step of the restore was: reboot device, which got me to the black screen - which is where I am stuck now.
All I managed so far is entering the fastboot mode, I could confirm this working by issuing a "fastboot devices" which listed the phone as available.
Anyone got any ideas to what went wrong and how to fix this?
update: after going through the unlock bootloader procedure again the phone boots normally again ( fastboot.exe -i 0x0fce oem unlock 0x[...] ) . Now the last problem is getting the TA partition back.
Is this even possible while keeping root?
Flash stock kernel .266 before restoring TA partition.
go to flashmode and flash the kernel.ftf, links of which can be found by searching.
this problem has been posted as FAQ in Bootloader unlocking relocking thread.
Thanks! I'll try this. I thought you only had to reflash the stock kernel if you wanted to relock the bootloader
I can't boot XZR(C5502) since i tried to flash a CWM based Rom.
1)Xperia ZR 10.5.A.0.230 ROOTED[Locked bootloader]
2)Recovery installed Philz touch,cwm,twrp by NUT
3)I have Nandroid backup also have TA backup.
4)I dont remember about USB debugging on or off.
5)I tried to enter in recovery but nothing happend.
6)While entering in fastboot blue LED lights up.nothing on screen.
Please tell what to do?
Please paste a link for ftf file(indian).I can't find 10.5.A.0.230 for C5502 indian.
Is it ok to flash nordic or some other varient of ftf.
1. Did you check if the ROM requires an unlocked bootloader?
2. Did you perform a factory reset in recovery before flashing?
If you can't enter recovery, it's likely that zip you flashed included a kernel, and the kernel flash failed because of the locked bootloader. Find a stock FTF (doesn't matter which variant, only thing that changes is the bloatware and the default language, which you can change on first setup, all Sony media apps are the same), flash it, unlock bootloader (make sure you still have your TA backup, if not, root and take it again), install recovery and try flashing the ROM again.
P.S. Fastboot only shows the blue LED, nothing on the screen, there's nothing wrong.
Good luck!

Yes BE2 will work after restoring TA Backup. I guess (not sure), restoring TA will lock the bootloader as well. Correct me if I am wrong :angel::angel:
