Root Unlocking bootloader

[chago360]

Can i have all the files to unlock the boot loader please?

Hey, there is no way to unlock the boot loader currently. We use bump which signs our boot.IMG and recovery.IMG to make them flashable even with the locked boot loader. That is all Dev work though, so there is really nothing anyone can upload and give you.

If you would like more info on doing something in particular, like flashing a ROM or recovery, i would all be glad to help point you in the right direction.

I thought we could unlock it with fastboot?

But in the other hand what is bumb? Is it a custom recovery?

You can run the "fastboot OEM unlock" command it it will unlock the boot loader. But on top of the boot loader there is another layer of security that prevents custom kernels, Roms and recoveries from being flashed, and that's where bump comes in.

Bump is a string of "magic" text/numbers that is appended to a recovery or boot image. It acts like a signing key, when boot or recovery is signed with bump and then flashed it tells the boot loader that the boot or recovery is from lg and is OK to flash, even though it really isn't from lg.

So no bump isn't a custom recovery, its just a method to sign a custom kernel or recovery so we can flash them.

On our phones and many other lg phones, unlocking the boot loader itself does nothing for us. Bump is a godsend or else we wouldn't have anything but stock Roms.

So do you flash bumb with an app or something?

Nope no app. You flash a recovery or a boot image that has been prebumped by me or someone else. There is twrp, clockworkmod and philz to flash that are prebumped already. Also my cm11 is prebumped too.

Stay with cwm recovery for now, twrp and philz have some big bugs that need squashed. You can however take a backup of your stock ROM right bow with cwm, and even of you want to, flash eduardogs slimmed stock ROM.
