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?

Click to expand...
Click to collapse
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.
Is this working to unlock the Vzw S4? How are we unlocking the bootloader currently?
There currently isn't a bootloader unlock for the S4.
I didn't think there was but there is a boot animation change/rotator tutorial in the themes and apps section but it states that the phone must be unlocked......I didn't think we had an unlocked bootloader yet! Just making sure I didn't miss anything.
there is a bootloader "bypass" but not a full unlock
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?
I have an Xperia Z2 with a locked bootloader. Will these methods for rooting and backing up data work with a locked bootloader?
Root method: http://forum.xda-developers.com/showthread.php?t=2784900
DRM Backup tool: http://forum.xda-developers.com/showthread.php?t=2292598
If not, you you please provide me with links to methods that work.
Thanks.
Bootloader is not unlockable.
The bootloader is not unlockable.
With a locked bootloader, you can still currently root and backup drm keys, but that's it. You cannot unlock your bootloader if it's locked. I have an unlock able bootloader but still keep mine locked anyways. I have root, and backed up drm keys, but that's as far as I go. If you're just looking for root access you're fine. You can flash stock based roms only.
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.
