As you may of noticed, (Possibly not) I've unlocked my tablet's bootloader, but, what are the benefits of having a unlocked bootloader? I only know is more ROM support.

Enhanced recovery capabilities as you can repair damaged system components (eg: borked recovery partition) from fastboot.

I've got to give one of the units back and need to decide which.
Since it's possible to flash CW recovery using ODIN both locked/unlocked bootloader devices, is there a benefit to having an "unlocked" bootloader?
I've been able to flash both locked/unlocked as well install Kernels..
I understand, nvflash can't be used on locked bootloader units.. but it seems (from what I understand and have read via searching), most everything can be accomplished via ODIN + CW.
Thanks!

Lock vs unlock means that if you are unlock you can flash kernels made for ubuntu and other linux distro. Locked bootloaders are generally limited to the samsung kernel so it would be harder to flash other things and make some serious mods that would require nvflash.
Thanks for the reply. Will keep unlocked. Cheers.
This probably is not important, as I've already upgraded to CM9 and using it happily as a daily driver. I've been thinking about buying the Asus Transformer Infinity (TF700) and was reading about the tool to unlock the bootloader. I do understand that the "boot" area of the NVRAM is un-writable, and to allow this to be writable is to chance having that section of memory fubar, meaning no boot, meaning bricked device, etc.
Anyway, when I started coming up to speed on CM9 and reading most all of the pertinent threads, I don't recall reading anything on a locked bootloader for the NT. I rooted, prepared a bootable SD card with the .zip file, boot image and a few other files. Easy, but no unlock code or anything. So did that process unlock the bootloader and overwrite it with CM 9 files?
On a similar note, where does one find a memory map of the NT, showing where the bootloader and other partitions are? IE, I'd expect that the bootloader would take up the first block of memory, with other areas defined after that.
The bootloader is not locked (on the roms) Bauwks has unlocked it for us.

If the original NT had a locked bootloader, then the process of flashing an new ROM was able to circumvent that?

The bootloader was never unlocked, as far as I'm aware. There was a flaw found that allowed the developers to bypass the bootloader and load custom images, including a new bootloader (cyanoboot).
Is it not impossible but not for every phone just for some special case?
If it can be done on some phones, how they can no need unlocked bootloader?
I know Sony's device can use CWM with locked BL, but it is "use" not "flash".
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.
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.
