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.
