[Q] Bootloader question.

How do I tell if it's unlocked or not? I went by a tutorial and I'm not sure if I unlocked it or not. As I'm not used to this Fastboot stuff.

Check the service menu and see if it is unlockable type *#*#service#*#* in the dialer

[Q] How I can unlock my bootloader ? HELP

Hi everyone ! I have a Xperia Arc LT15i and I found out using *#*#7378423#*#* that I cannot unlock bootloader (Bootloader unlock allowed: No). How I can unlock my bootloader because I want a ROM like CM9 or JJ's Hybrid and it`s must to have bootloader unlock. Please help me with unlocking the bootloader, or please help to find a ROM like CM9 without unlock my bootloader. I want to say that I am not very skilled Waiting for more tips.

download flashtool then Plug in > unlock bootloader
it will guide you to sony's web page, copy paste the code and let flashtool unlock it

Actually JJ's ROM doesn't require an unlocked boot loader.

If you have bootloader unlock allowed:no standing, then you can't unlock it with Sony service, because your IMEI number is then 15 symbols long, so no way for unlocking bl without paying for services like setool

Hi,
If you have bootloader unlock allowed:no , you can unlock it with Omnius :laugh:, but is not free, 15€/unlock .
I unlocked my LT15i with Omnius, I had "unlock allowed:no" before.

So .. I can't unlock my bootloader, only if I paid :crying:

Setool & Omnius links?
you guys got any links related to this Omnius and Setool things? or other alternatives for Xperias stating that unlocking bootloader is not allowed?.. I had thought that if they say so, it was just impossible to unlock...

Unlock for free

just go here unlockbootloader.sonymobile.com

I'm starting to get angry I said and ludz179 in answer above you I can not unlock the bootloader so because the Service Info says Bootloader unlock allowed: No

was only giving info you say your phone says cannot unlock boot loader then from wat iv seen there is no way to unlock it.
but there is lots of roms out there that run well on none unlocked bootloaders and using new flashtool seems easy plus using DooMLoRD to root the phone .. I think the only way to do it would be to send it to sony service to unlock but knowing them you go no chance
just trying to help thats all

Can't help enquiring.You mention that there are several roms that are available which does not need to have the bootloader unlock.Could you give me the links please.

[Q] Does this method unlocks bootloader on "unlook bootloader: NO"?

I apologize if i repeat the question, but recently discovered this site:
http://w**w.unlockroot.com/
Does this way it is possible to unlock the bootloader on xperia s blocked?
And then do consseguir root?
Attention: my xperia s is referring to the "no" in unlok bootloader!

If your boot loader says no, then it can not be unlocked anyway possible. If it can root maybe it will.
Edit: it also conforms on the website that if your device say bootloader: no, then you can't unlock it.

you must go to Sony's Offical page to unlock the bootloader
all third root tools cannot unlock Sony's bootloader in the root progress
(except the root tool suggest you to enter the bootloader-unlock key
(sorry for my poor english

Not entirely true... When it was launched some dealers had access to Sony certified Servers and they could unlock the bootloader status.
The problem is that Sony closed the servers and since then, only Sony can do the change.
So, to get clear: at this time, only Sony can change the lock of the boatloader authorization to Yes.
To do so you have to contact your carrier or Sony in your country.
It is not impossible, but it's only available trough the official channels.

Thnks. Can you tell me how I do that?

Go to any mobile service and ask that they can unlock your simlock in xperia m, this should unlock bootloader too.

Bootloader has nothing to do with simlock so it won't unlock the bootloader

I don't want unlock the bootloader, just the simlock...

Unlocking the SIM will not touch the bootloader

Unlock simlock=unlock bootloader

Mine is SIM unlocked and the bootloader isn't unlocked had this question loads of times in the x10 forum and it doesn't do anything to the bootloader as that's just for custom kernels to be flashed if you unlock it via the guides on here SIM lock has nothing to do with the bootloader as the bootloader only runs the operating system boot it has nothing to do with the SIM lock protection wrote into the firmware that carriers put in as an insurance to them so you have to use their network but it can be removed via an unlock code that you enter with the new SIM installed

Unlocking the sim lock doesn't unlock the bootloader. My XM sim and Bootloader was locked i unlocked the Sim lock but the bootloader is still locked

My eyes!

so... what should I do?

Go to a mobile shop and ask for SIM unlocking or you can search the net for unlocking sites either way you will have to pay for the SIM unlock. And don't worry about the bootloader as it will not unlock that.

BL unlock failed?

Hi guys,
A friend of mine wanted to install kitkat on his xperia m, I have a xperia too (sp) so I thought I could easily help him! We rooted the device, made a TA backup and we tried to unlock the bootloader. We followed all the steps on the sony site and when we entered the command in cmd it said [FINISHED] and just that I remember when I unlocked my sp's bootloader it said stuff like this "[BOOTLOADER]unlock requested" But it didn't do this on my friends M! I thought it was fine so we proceeded and installed archidroid together with it's custom kernel. We rebooted the device and it didn't do anything at all (just a black screen, not responding to anything) so that just tells us that the bootloader is NOT unlocked and not accepting custom kernels. We had to restore the device with flashtool to get it up and running again
Does anyone know what's wrong?

Open dialer and put in *#*#7378423#*#* then go to service info then configuration and on the bottom at rooting status. if it says yes then it can be done if it says no then there no possible way to unlock it at all. Screenshot of mine
