[Q] re-lock bootloader? - Galaxy S II Q&A, Help & Troubleshooting

with all the security related threats recently i'm realizing i really need to re-lock my bootloader.
any links on how to do this? i've searched and it's all about unlocking and a few on un-rooting.
i need to retain root, but want a locked bootloader so if i lose my phone it's less likely to have its data siphoned.
CWM, unsure of version
thanks!

How to unlock a bootloader block by sony

Hi, browsing your forum I understand that the locked bootloader could be unlocked thanks to a patch or special handling, could someone explain to me the method to use so that I can do, I seek to any price to get rid of the bootloader lock that prevents me to test custom rom or kernel flash is required and therefore impossible because bootloader not UNLOCKABLE
It can't be, all they managed to do was act irresponsibly and brick some phones.
cant unlock by flashtools?

[Q] How to Lock Bootloader After Unlocking Bootloader

I have this PadFone S for over a week, and it's my 5th android device, but certainly the 1st one having a locked bootloader. So far I have read how to flash stock firmware, how to root and unroot, which requires unlocking bootloader first using CrowLock, how to install CWM and CM12 etc. I haven't try anything yet (still uprooted, and my bootloader is still unlocked).
One question still unanswered, is there any way to lock the bootloader after it's unlocked ? Perhaps by using the CrowLock app, or simply flashing stock firmware ? I need to be assured that any changes I do is reversible.
Thanks in advance
I too purchased the Padfone S and have the same question. Also, does anyone know if flashing crowlock will void the warranty of the phone? Can someone who has unlocked their bootloader using crowlock paste the output of "fastboot oem device-info"?
Does Asus' bootloader not check the signature for the recovery partition before booting from recovery? Given that everyone is flashing the recovery after rooting and running crowlock from the recovery, it seems so, but I'm not sure.
Anyone know if the bootloader's source code is available? I know it's based on the littlekernel, but I'm not sure which version it was built from.
Bump! I need the answer too.

Nougat, locked bootloader and DRM hack?

Hi.
Last year I unlocked bootloader and rooted my Z5C before it was possible to backup the TA and now I'm a bit lost in what to do. Yesterday I used Flashtool to install 32.3.A.0.378 but the problem is the DRM is gone. I have a locked bootloader so apps that check for this finally work. Therefore, if possible, I want to stay on locked bootloader a bit if it's possible to put in a DRM hack so camera pictures are nice again.
Is it possible to keep bootloader locked and install AndroPlus kernel? Or is there another way of getting DRM back without unlocking?
Device is not rooted and there's no recovery on it. But it's smooth like hell! :laugh:
Any suggestions?
No, not possible.
If you want a kernel with drm fix, you have to unlock bootloader

locking the bootloader

I have a question regarding locking the bootloader, but I'm not sure if it's entirely possible.
Can I keep root access on the phone if I re-lock my bootloader?

Why does updating not require bootloader unlock but downgrading does?

Can anyone help me understand why when my phone gets an android update it can install it without unlocking the bootloader but if I wanted to downgrade my android version I need to unlock it?

With updating, it is by system settings or OTA. However with downgrading, the system cannot let you downgrade by default, as there is no system setting for that - you can unlock the bootloader and then downgrade your version.
To answer your question, YES.
You need to unlock the bootloader to downgrade.
