Hi,
I have a question about relocking bootloader / restoring back to stock.
I found out it was possible to relock bootloader using Flashtool. If I flash a stock Sony ROM using Emma, and then relock the bootloader with Flashtool, does it mean I will be back to factory state ? Will I be able to do OTA updates etc. ?
Or is there no way back ?
I did not save the TA partition before unlocking...
Thanks!

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.

- Restore your TA partition using the tool 'flashtool'
- use Flashtool and press the BLU button and choose "Relock".
If you are on a custom ROM you wont be able to boot. You'll need to be on a Sony ROM, with a stock kernel.
Otherwise don't lock the bootloader.

Thanks, so no need to flash TFT
Hi
I rooted with the Geohot make it rain method and then backed up TA before unlocking boot loader. I currently have Doomkernel.
To restore to stock, is there a flashable stock zip somewhere for .402
Then is it a case of restoring TA (which relocks BL?) And then unroofing?
Thanks

Safest way:
Factory reset the phone (on the phone)
Flash a valid ftf
Re-root
Restore TA (BL will LOCK)
Reflash the ftf if you want to lose root
.
Yes, you can download a image for your device and then flash it with the flash tool. It can also relock your bootloader.

NOPE
ftf will NOT relock the bootloader.
(OP wants the BL locked, not relocked too - only TA backup can do this)

Yeah you're right, ignore me and my too fast reading
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
Just curious, if I flash full stock on my phone after having TWRP, will the bootloader be relocked? And will the OEM unlocked 7 day issue come?
If it doesn't relock, I should be to just flash TWRP again right after? Thanks.
