hi all
i tested if SEUS restore the lock to our bootloader and rechecked my bootloader after restoring my phone to stock it seems that the bootloader stayed unlocked so unlocking bootloader is proved to be permanent unless you locked it again via flash tool and stock kernel for U20i

You are so wrong, neither seus pcc or flashtool relock the bootloader, you can reflash the firmware all the times you want and your bootloader stays UNlocked . The only tool that RElocks the bootloader again is S1TOOL.

i didn't mean to lock the bootloader via flashtool it was only to say that the kernel itself didn't change when used SEUS to restore stock firmware and noticed as side seeing that the bootloader is still intact and unlocked
i already know that only the steps mentioned in Spyder post with s1tool and flashtool can relock the bootloader but i tried to test SEUS if it does anything in that case.

What I have to do?
Currently I am going to
Relock bootloader
Update via air or on website via PC.
Will that work?
should work, but why you relock your bootloader? follow just the Instruction from Bin4ry with unlocked bootloader... works fine and you got root then
can you link please?
So many dublicated threads
You dont need relock bootloader...
Download the oficial firmware, and install with FlashTools (version 8.0).
Its simple...
Is it a different method with an unlocked bootloader?
Or just flash the ftf file with flash tool?
Just flash.

Accidentally, I found a way to relock bootloader (sk17i) after unlocking by testpoint.
This is what I did (I'm just a little more than a noob):
1) connected my phone in fastboot mode
2) used fastboot toolbox of flashtool and select 'flash system'. I tried flashing the 'system.yaffs.img' made from
a CWM nandroid backup of stock rom (any rom would probably work).
3) flashing completed but my phione will not switch on anymore(screen won't even light up, just a quick LED light).
However, it can still be connected in fastboot and flashmode. Flashing custom kernels didn't work though, it showed some error that root is needed.
I thought I had screwed my phone for good. Luckily I opened s1tool and saw my bootloader still locked (capital 'R' instead of 'r')
I unlocked again by testpoint method and was able to flash kernels again and restored my phone.
The point is, when the bootloader was locked again, one could have used SEUS and everything will be back to factory state with DRM :good:
(If anyone wants to risk, please try it out. I'm poor :crying: This is my only phone)
Testpoint method patches the bootloader(not unlocks), so that unsigned custom stuff can be installed.
If you want to relock, open S1Tool and use Restore option.
You don't have to relock in order to use PCC or SUS.

Hello.
I was in a custom rom and it was 4.04 ICM (I don't remember which one) and I already had an unlocked bootloader (which I couldn't remember) and I tried to re-unlock it
Now on my phone the Sony Ericsson logo re-appeared and it won't boot (it was Sony with my custom rom)
I used this method for unlocking bootloader

I have this CWM

Now what should I do?
Should I flash stock firmware?
Should I flash another custom?

You relocked bootloader, right?
Or did you unlock it again?!
Anyways, if you did a relock, you must flash a stock ftf and/or a ROM for a locked bootloader.
Because, your custom kernel based ROM won't run on a locked bootloader.

I'm trying to go back to stock from CM12.
I tried flashtool to flash a stock image, and after I selected relock bootloader.
it says it's gone OK, but stock doesn't boot after.
If I go back to flashtool, and I select BLU, it gives me the option to relock the bootloader! I thought it was locked already.
what can i do?
thanks

This only works if you unlocked the bootloader using the official method of unlocking the bootloader.
If you did not do that and perhaps unlocked bootloader using flashtool the only choice you have is to restore the TA partition.
That said if you made a backup of the TA partition before unlocking the bootloader.
edit: What is the status of the phone when you say "stock doesn't boot after."?
Does the kernel not boot? = vibrates three times when power button being pressed.
Does the phone boot but get stuck in a bootloop?

Somehow, after a second flash of the stock ROM, and selecting to wipe data, the phone booted in stock, and works fine.
I still had an unlocked bootloader, and flashtool relock or fastboot oem lock wouldn't work.
I managed to find out what the problem with Backup TA tool was, I replaced the adb previously, but I didn't need to, once I went back to the standard adb, the TA restore worked, and with it, the bootloader locked!
this is now solved. thanks for the help.
one question now.
Is this now the same as stock stock? will i be receiving OTAs or should I do a repair with PCcompanion just to be sure?
rather not if not necessary as I already rooted
Guy's I need to relock my bootloader
I tried with flashtool but it's not working
