[METHOD?] Relock the bootloader (unlocked with test point method)

[CappyT]

Hey guys.
Two days ago i have flashed back my SK17i to stock rom.
I updated from FOTA.
I didn't know i must relock bootloader before updating from FOTA, so i bricked my phone.
After 2 minutes of deep panic, i've flashed the relock .ftf file, but it won't work on phones unlocked with test point.

So, i found a way to relock bootloader and go back to stock. (On forums i didn't see any guide regarding the method to relock bootloaders unlocked by test point)

I've done in this way:
1) Flashed stock kernel
2) Flash the .ftf relock file
3) With S1Tool hit restore

The phone is now bootloader locked, without losing of DRM!

Did you tried to download the latest version of flashtool?
Also, try to re-download the ftf file from another mirror, you should able to relock bootloader.

I just registered to confirm this method works. I foolishly allowed a FOTA yesterday and bricked my phone. It was unlocked via testpoint so the relock method didn't work, even though I tried it! I also tried flashing with S1tool with generic firmware and that didn't work. Then just out of curiousity/desperation I clicked on the RESTORE button in S1 and my phone actually started but was now locked again. I re-did the testpoint unlock this morning so now my phones fully updates and working with my SIM of choice.

I don't know if you need to do all the flashing as it may just be the RESTORE that does the trick. I definitely won't be allowing any OTA from now on. Lesson learned!

Just to confirm, so long as I do the update via PCCompanion or SEUS software I wont need to do all this?

Files to download please?

Files to download please?

What files?
If you unlocked your bootloader with test point, no need to flash anything, just press restore button in s1tool.
