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.

OK than. Thank you, and one more thing, does Jellybean work work with stock ROM ? Will I be able to relock the bootloader?

I don't understand the question, what kind of jellybean work?
If you mean custom non-stock based ROMs like CyanogenMod than no.

Hi!
I'm just wondering if it's safe to flash the old GB bootloader, the one that allows to use the USB JIG to reset flash counter, and stays with this old bootloader, while using JB ROMs (mainly AOKP or CM).
Is someone using this old GB bootloader with newer JB ROMs??
Thanks in advance.

By the way... is there any way to know wich bootloader version are you using after flashing a new ROM?, I know most custom ROMs (AOKP, CM, ...) don't contains any bootloader, but not sure about others or about Samsung leaks.
So... is there any way to check if flashing a ROM changes the bootloader?

Sir all stock rom did't touch your bootl oader, coz they are zip file and flashing through recovery, and boot loader flashing only with odin . After flashing boot loader will erase your phone. And to flash this do some search first.

Flashing with Odin in .pda section, if I'm not mistaken. I dunno if you can back up your boot loader. But is good to have ICS and GB boot loader in 2 different tar files, just in case you want to switch back.
You can't back up a bootloader on SGS2. And frankly, given the reason you're wanting to flash it (so you can use a jig) & given there's an alternative (Triangle Away), I'd advise you not to flash it.
You don't need to. You only mess with bootloaders when you have a specific reason to do it; I.E the rom you want to use won't boot without a 'recent' bootloader.
Given the risks of rendering your phone unbootable & only fixable by JTAG if it barfs & given there's an alternative, wanting to use a jig doesn't strike me as being particularly sensible.
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,

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.

Ok so after I posted a previous question about not having bootloader access, I've realized there is something wrong with my xzu. HOWEVER, I CAN get into flash mode to flash factory firmware. The bootloader was unlocked using a tool that I downloaded, but without access to the bootloader, I can't flash any custom recovery so I can flash a different rom.
My question is: Can an FTF file be created from CM, or aosp, and flashed using flashtool? There is a guide over at xperiablog (Here), but they don't mention anything about non-official firmwares, and I don't see any in the forums here, so I'm assuming that it's either not possible, or not worth the effort for most people.
Can this be done? I have no other options.

I'll take a video of it tomorrow. It doesn't want to respond to fastboot. I never get the blue light when booting holding volume up. It just blinks amber and green real fast, then it's in flash mode no matter what I do. And like I said, I used some tool to do the boot loader unlock, I think it may have even been flashtool.

Okay you must reflash the stock kitkat Firmware, that is the onliest way to recover the fastboot mode.

Maybe restore your TA Partition with your TA Backup
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?
How do I unlock the bootloader and install whatever kernel I need?

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.

Perfect! I unlocked the bootloader by using the instructions on sony's website. It did the trick, and CM11 is running successfully.
Thanks so much!
