Hi, I'm having some issues relocking my bootloader, as I'd like to go back to OTA updates.
I'm currently running the below ftf and kernel:
C6802_14.3.A.0.681_Generic HK.ftf
681_jackie099.img (by jackie099)
I tried relocking the bootloader using Flashtool 0.9.15, and according to flashtool it worked, but it's nothing but boot loops after that...
I thought that maybe I need to go back to a stock kernel first, but unfortunately, I can't find one after extensive googling...
Any ideas?
All the FTFs have a kernel in them.
Do you still want root? OTAs probably wont work with root. If you want pure stock just flash a FTF after restoring the TA backup.

having a modified kernel like jackies wont allow you to boot. (locked bootloaders will only permit a totally stock ROM)
So to have root and recovery you will need to have an unlocked bootloader.
actually... you could flash your ROM... flash jackies kernel and then root.
Then flash the stock kernel.
... and then you can lock your bootloader and still have root.
.. and it will boot.

After flashing this file 'Xperia_U_ST25i_Relock_Bootloader.ftf' to my Xperia_U, the phone won't boot again
I had to flash again with 'ST25i_6.0.B.3.184_O2-CZ.ftf' in order to get the phone working gain
This also made me lose Root, so I had to reflash again with 'Xperia_U_ST25i-ROOT-ROM.img'
(and unlocking again with fastboot.exe -i 0x0fce oem unlock 0xkey)
so, it seems there's no way of keeping the phone rooted and locking the bootloader
(I want to lock the bootloader locked in order to get updated to 184 though PC-Companion)

I own an Xperia S, I flashed a custom kernel to root then flashed back the stock kernel and locked the bootloader again, the phone works perfect and kept the root!

Too keep your phone rooted you need to keep its bootloader unlocked and if you try locking it again you might brick it!!
So if you want to keep your root and bootloader locked then here's what you should do
1)Unlock bootloader
2)Flash a custom kernel which roots your phone
3)Flash with stock rom
Note : if still not rooted then untick the option in flastool to skip flashing kernel when flashing with stock rom!!
Pls correct me if m wrong!!

Thanks, so now I need confirmation from an Xperia_U owner..
Anyone flashed Xperia_U_ST25i_Relock_Bootloader.ftf' and the phone kept working?
.
What I want to keep is:
---------------------------------
Kernel: Xperia_SSpeed_kernel_v6.1.zip
ROM: KA03_Xperia_SSpeed.zip
Then, lock bootloader again, withOUT losing ROOT
and then update to 1.84 (via Companion)

You cannot update via pcc even with Locked BL if you have custom rom or kernel.

So what the best way/order to update the phone to 1.84 and also get Root?
Thanks
Hello there
Yesterday i did the root trick for 6.1.1.B.1.54 with flashtool, where you downgrade to an earlier kernel (.544) in flashmode, push superSU and then upgrade again to .54.
In the dev forum for the Xperia P i have found the Sliding_XP kernel, which i want to install.
The question is, do I need an unlocked bootloader to do this? Or is it just flashable via flashtool?
Also, it says in the kernel's thread that the package also contains CWM recovery. That removes the fastboot mode, right? (since it is accessible via vol down, same as for fastboot)
Sorry for sounding like an xda-noob (Yeah, i've seen the video and I should hate myself).
Thanks in advance!
It doesn't remove anything.
Volume down is for flashmode btw.

Oh, sorry. I rechecked and yeah, it is the flash mode. fastboot is volume up.
The question remains: Do i heed an unlocked bootloader to install this?

As I said, i have the rooted 6.1.1.B.1.54 update, and my bootloader is locked, no other hacks have been done to the phone

I see. I know that OTA updates are no longer available upon unlocking your bootloader, nor some services such as trackid (which doesn't bother me), or Download muic info in the walkman app. Are there any more disadvantages?
Also, when Sony releases the official promised JB update, the only way to update it will be with the ftf file, right?

First of all OTA updates not available and others you know that.....
next is your warranty will be void most probably......
Sony officially said that it wont release JB for SOLA so anyhow you wont require OTA for that......
and i bet you will get JB only through XDA.......

I don't have a sola, i have a P
Alright, so I have unlocked my bootloader. (Horray.) It did delete everything, but for some reason, SuperSU is still there.I hope that rooting before unlocking the BL did not do anything bad to it.
As a total noob who doesn't want to brick his phone, someone please tell me what exactly i need to do now in order to install the kernel mentioned above
In other words, how exactly do you install kernels? With recovery? I don't have that installed in my phone. Also it says that the kernel comes bundled with CWM. This confuses me.
What mode do I need to select in order to flash it on my Xperia P? Flashmode or Fastboot?
Also, in case anything goes wrong and my phone gets bricked while flashing, is there any chance that the phone might be permanently bricked, as in not revivable via either entering fastboot or flashmode to flash a new official fresh firmware file?

Slowdown dude, your to fast...it depends on the kernel,if its .img just flash it via fastboot if its a .zip file flash it via cwm recovery,i assume you have a non recovery, coz your using a stock kernel, i recommend you to flash sliding xp kernel,it has cwm recovery built in,...happy flashing,

I read in the Developers forums that you can get Cwm for Locked Bootloaders. Ive been trying to get it for a week and can this be done? I bought the Ultra at Bell and it says its model number c6806 and its locked.

Yes. here it is:

However just because you have CWM, doesn't mean you can flash ROM's.
All you can do is flash Root, and other mods.

sorry for the quick question, but would that work on the C6802 on .257, with locked bootloader? i've been wondering if i could get root without unlocking the bootloader(to preserve warranty).

yes you can root with a locked bootloader.
to unlock your bootloader you need to have root access.
You can always backup your TA partition, and then unlock bootloader, and then restore the TA partition and restore bootlock as well.

hey thank you sir for the response. I got my phone with .257 version already on it tho, and from what I'm reading, I can't find a way to root on .257 without unlocking the boot loader. is this correct?
as I see it, the only option I have on .257 is to unlock the bootloader with the Sony method, but no way to root first. am I mistaken? thanks!

What you could do is use flash tool to go back to another firmware, then root, and then update to the newest version. But not flashing the kernel. then you can flash the modified kernel with CWM, and then flash the new kernel afterwards.
I think there is a tutorial on here that tells you how to do it.

ah yes, OK, that's what I was wondering, whether it is possible to downgrade the firmware with a locked boot loader, using Flashtool. perhaps I will try.. thanks
I just remember on some other devices I've had, a locked boot loader wouldn't allow a firmware downgrade.
So here is my issue. I updated my android on my Xpreia U St25i to KitKat and in the prossess I had to unlock my Bootloader and now I cannot lock it. I tryind flashing it with flashtool with many ftfs that I found on the internet but the result is always the same. After the flash the phone does not start. I click the power button but the led flashes for a sec in green light and thats it. It seems like the phone is stuck into flash mode. If anyone has any ideas, phease help!
Thanks in advance!

You unlock the bootloader to enable boot custom kernels not made by Sony. If you relock it won't boot custome kernels because the bootloader is "locked" to boot Sony kernels only.
You wank kitkat, bootloader must be unlockedm and there is no real reason you will want to relock your phone.

Well one thing is that I cannot update my PC Companion to a newer version so I cannot restore a backup and I read that this is because of the unlocked bootloader. Also there are occasional reboots of the phone with no particular reason.

PC companion is updated regardless of your bootloader, it will update without a phone being connected.
I don't think you can restore backups to custom non-tock-based ROMs with PCC anyway, you must choose stock(or custom stock-based) or custom ROM.
If you want to re-lock, you must use stock ROM and kitkat does not work with it.

I don't understand the question, what kind of jellybean work?
If you mean custom non-stock based ROMs like CyanogenMod than no.
The other day, I set about installing Cyanogenmod 11 on my Xperia Z2 D5603. I was already rooted on the stock rom 4.4.4 Kitkat 23.0.1.A.0.167. I used flashtool to downgrade to 4.4.2 17.1.2.A.0.314, rerooted it, and installed dualrecovery from this link: http://forum.xda-developers.com/showthread.php?t=2785598
But upon choosing reboot after flashing the custom ROM via TWRP, the phone went dark, and wouldn't turn on. The only response I got was a quick vibration every second or two if I hold down the power button. I could not access recovery either.
I was able to revive it by using flashtool to reflash 4.4.2 17.1.2.A.0.314. I tried the same procedure with AOKP ROM, which had the same result. After trying many different things, I realized that factory reset, or wiping 'system' under advanced wipe would cause this to happen. Flashing without factory reset either returns an error, or finishes, but doesn't actually flash the ROM (stock ROM boots)
How to I flash a ROM without this happening? Any help is appreciated.
Have you unlocked your bootloader? It doesn't sound like it.
These roms require another kernel and you need to unlock your bootloader to install it.

I thought that the fact that it was successfully rooted meant that the bootloader was unlocked. Is this not the case?

Hmm no.
Root ! = unlocked bootloader.
Go to the sony website ( http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader) to get instructions to unlock your bootloader.
But with your first assumption in mind, I suggest you read up about it first. Understand the risks and limitations.
