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!
As we know, an Android phone is first controlled by the bootloader.
Only the bootloader can read/write the NandFlash, so, if the bootloader is locked, then flashing commands issued by fastboot will fail.
My question is:
If the bootloader is not unlockable by design, how to root a phone?
Hey guys,
I have a question regarding locking the bootloader, but I'm not sure if it's entirebly possible.
TL;DR: Can I keep root access on the phone if I re-lock my bootloader?
Context:
When I unlock the bootloader, I am able flash custom roms and grant root access to APKs.
To do this, I must first go to "developer settings" and "allow OEM unlocking". Then I will be able to unlock the bootloader.
This allows me to install Cerberus, an anti-theft apk, as a system app.
However, in case the phone gets stolen, If I leave the bootloader unlocked, I am allowing anyone to flash over my phone, thus wiping Cerberus with it.
To prevent someone from tampering with it, I must "allow OEM unlocking" in the developer settings, which can only be toggled when the bootloader is locked.
Basically, I want to be able to unlock my bootloader, root my phone, install Cerberus, and re-lock my bootloader to prevent further tampering, while retaining root access to the phone. Is this possible?
Is this possible?
Don't know if I was confusing in my explanation, but I hope not.

I'm guessing the same question, will be impossible to steal a phone with Cerberus and locked bootloader.
If Cerberus is a system app it doesn't even need the root to work, isn't it?

Which phone are you using?
In many phones, bootloader can be locked after rooting, without losing root.
Are you sure locking bootloader will prevent someone who steal phone from unlocking bootloader again? I don't think so.
I gather that it is necessary to unlock the bootloader in order to root - is this possible to do on the Verizon version? If so, could someone point me towards a tutorial, as I have only found posts on rooting, not unlocking the bootloader.
Hi,
I was just wondering what makes a bootloader locked or unlocked. I know what bootloader unlocking is, but what actually changes in phone to make it stop checking boot, recovery and other partitions? And how do it knows if a partition is stock or not?
Thanks.
