[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.

Nope. Bootloader unlock allowed: no means no current way to unlock it.
BTW search for this next time please as it has been discussed ad nauseum.

Today i was about to unlock my bootloader using SE Bootloader Unlocking v1.6(http://forum.xda-developers.com/showthread.php?t=1560613) but before doing so i used s1tool to identify my device.Here is the screenshot. Check my S1_EROM version it starts with "r" not "R".so it's alreay unlocked? How do i know(check) my mobile has bootloader unlocked?
I bought this mobile almost a year ago and it was brand new from stock.So not sure it's already have bootloader unlocked since i haven't unlocked the bootloader yet.I just want to know what's happening.Sorry if this question has already been asked as i am kin of noob(but have rooted and flashed ROMs using flashtool and CWM) and want to know what's the bootloader status.If anyone know how to check bootloader unlock staus it would be very kind to share as i am gonna unlock my bootloader and need to recheck if it's unlocked properly so that it won't brick my phone.

Try flashing a kernel is the obvious and simplest answer.

So if my bootloader is locked it won't let me flash custom kernel like(boot.img of cynogenmod) or it will brick my phone? You link doesn't explain anything on how to check bootloader unlock status."bootloader unlock allowed:yes" will be for those devices whose bootloader can be unlocked but it doesn't tell you if bootloader is unlocked or locked.
I simply want to unlock my bootloader.Then flash cynogenmod.I want to make sure bootloader is unlocked properly before flashing cynogenmod kernel.If flashing boot.img on bootloader locked device won't brick my phone then i am ready to go.Just need conformation on what happens if i flash custom krenel and rom in bootloader locked mobile accidentally.

When your rooting status says
"Bootloader unlock allowed: yes"
Then the bootloader is locked..
If it says
"Bootloader unlocked: yes"
Then your bootloader is unlocked..
Simply dial *#*#7378423#*#*
Then find your rooting status..
And I think you should use the official way to unlock bootloader.

HAhaaa unless that shopkeeper imported the phone,unlocked bootloader and flashed a kernel.Place where i live doesn't have authorized sony mobile distributors.So they import from somewhere.
My booloader was unlocked whole time after purchasing it.It was new when i bought but no sure now.Anyway i am satisfied with my purchase a year ago as i haven't got any problem till now except that famous house crack.
I have flashed Cynogenmod successfully.Thank you all for the help.You guys gives some courage for nervous guy like me who are tempting to do new things.

Bootloader Unlock Allowed - NO!!

I just check my ZL and it says Bootloader Unlock Allowed - NO
Does that mean I will never be able to unlock the bootloader and install custom ROMS? I have my phone rooted and its also SIM free if that matters. Would someone be kind enough to explain the consequences?
TIA

Don't worry mate (if initially your "BL unlock allowed" was "yes")! I read it in the XZ rooting thread that if you root with a locked BL then you might have a bug resulting into BL unlock status to not allowed. Doomlord has also posted a fix for this, i think. Have a look at this thread. Hope it helps.

The thing is, I didn't check if I was allowed to unlock my bootloader before I rooted it (banging my head against a wall as I type this). Any way to find out?
EDIT: Nevermind, I see that I have to flash it and if I had an unlockable BL, the status changes to yes, and if not, then nothing changes. However, how do I flash this seeing as how there is no CWM out yet?

AW: Bootloader Unlock Allowed - NO!!
There is CWM:
http://forum.xda-developers.com/showthread.php?p=39157612
But just for unlocked bootloader...

CWM for locked bootloader would be coming... krabapple is working on it...

hi mates,
if unlocking BL, i will lose BE2 & WM right? sr if this noob question was answered before

AW: Bootloader Unlock Allowed - NO!!
Yes, you loose that functionality.
And please don't ask the same question in several threads. Ask once and have patience until someone replies.

I have Xperia Z LTE C6603 with
bootloader unlock allowed:No
I Can change this to --> bootloader unlock allowed:Yes ?
as I can change it ?
Thanks.

As per my knowledge if the status is "NO" then u cannot unlock the bootloader.

Hello Gens2Rasta,
There is no way right now to unlock the bootloader on a phone with the "Bootloader unlock allowed: No" status right now. My only advise would be that you should contact your carrier and ask them if it's possible for them to change the status of your phone so that you can unlock the bootloader.
Have a great weekend,
