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'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.
Sony Xperia Neo V
Stock ROM 4.0.4 (Updated 4.0.3 to 4.0.4 via OTA)
Rooted via DooMLoRD
CWM Recovery installed.
I need to find out if my Xperia Neo V have a locked or unlocked bootloader..?
I have read through different thread and have googled as well, but still was not able to get a concrete answer.
I have never unlocked it myself, not intentionally atleast.
When I check via *#*#7378423#*#*, it says 'Bootloader unlock allowed: Yes'. Some guys around XDA says if its unlocked, it will say ''Bootloader unlocked: Yes' but others say it will show the first one regardless of the lock state.
PC Companion and SUS can detect it just fine and I can repair and update my phone, which leads me to believe its locked.
But then, I can get into flash mode, use flash tool to load different ROMs and also have CWM installed - doesn't it need a unlocked bootloader?
And, if I am on a locked bootloader, what's the advantage of an unlocked one then, what am I missing?
Bootloader unlocked: Yes only means that your fastboot is unlocked,that your phone isn't SIM locked, not that your bootloader is unlocked.
Being able to enter flash mode, flash different rom's, cwm doesn't mean your BL is unlocked.
There are rom's that require custom kernel, if you wanna use those rom's you need to unlock your BL.
Advantage is anything that can be done with custom kernels, mainly overclock, undervolt, change some parameters...
Go to Neo V development section, in one sticky thread you can find s1tool. Get it and identify your phone with it.
Just a fact that you didn't unlock it tells that it's locked. All Xperia phones have locked BL's. All 2011 Xperias with sim lock, have locked fastboot, which means you need to pay to unlock it and by that you enable fastboot and unlock your BL.
Thanks buddy (button pressed). So, unlocked bootloader means warranty gone forever, right? Irreversible?

Well, if you use official method, even if you relock it they can see in service center, when they connect it, it will show that DRM certificate is missing. I'm not saying they will look for that, but it will be visible.
In my opinion patched bl is best option, with s1tool. Also you can relock it. As far as I know nothing will pop up on their PC.
Alright buddy, got the idea. Thanks a lot.
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.
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.
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.
