In the dialpad? Which ROM are you using?
If you're using CM or MiUI, you won't see it, but your BL is definitely unlocked.
Why I should post it when it'd be for X10, but anyway it's a generally SE/Sony menu.

say, what does it exactly say?
and which to choose?
after typing it in, i get;
-model info
-software info
-SIM lock
-configuration
where to go exactly and what would it say to know BL is unlocked?
thanks.
----edit
saw the answers here http://forum.xda-developers.com/showthread.php?t=1488346
Dial *#*#7378423#*#* . Then go to -> "Service Info" -> "Configuration". If there is:
Bootloader unlock allowed - Yes << this means that your Bootloader is Locked
Bootloader Unlocked - Yes << this means that your bootloader is unlocked

best way to check it is with S1TOOL. Just identify your phone. If it gives device id with captial its unlocked (if i dont remember wrong). You can also try to hotboot a kernel with CWM to see if it works
code:
fastboot boot FILENAME.img | FILENAME is the name of the img file (kernel)
if it gives blue led on boot its unlocked

How Do I find out the bootloader status (Locked/unlocked ?) of my xperia ARC.

thanks a lot in advance.
dial from your phone to check status :
*#*#7378423#*#*

dear gogo,
I've tried that, the service info will tell you "bootloader unlock allowed = yes"
it will not tell you whether your phone is locked or unlocked state!
It will tell you.
Mine is unlocked and says " Bootloader unlocked: Yes "

So that means I can do the same exercise again to unlock I mean official way?
In that case se will provide me new code to unlock?
I don't remember the old code they provided
Regret for the seeking the clarification again as I don't want to endup in trouble later.

it's ok.
I've tried it.
the unlock code is still the same code you had received before.
the remaining question is whether you sure to unlock it again or not, as standard user doesn't need to do such thing.
bravery comes from experience.
that's it bro.
I think your problem has solved.

Bootloader unlocked: Yes
Means fastboot is enabled and the bootloader can be unlocked the official way
Bootloader unlocked: No
Means fastboot is disabled and therefore the bootloader can only be unlocked by other means
The best way for you to check your bootloader status is do identify in s1tool or similar

Then your bootloader isn't unlocked.
Keypad, type in *#*#7378423#*#*, Service Info, Configuration
If you see this
Code:
Bootloader unlocked: Yes
or this
Code:
Bootloader unlock allowed: Yes
then you can enter fastboot mode.
If you see this
Code:
Bootloader unlock allowed: No
then you can not enter fastboot.
Anymore questions?

You have to make sure that your phone has unlocked bootloader, if it says "bootloader unlock allowed: yes" it doesn't mean your phone is unlocked, it only tells you that it can be unlocked.
If you have TrackID, try to play it, if it can be played, then the bootloader is still locked.
For unlocking, try the link below. And don't forget to thank them.

Put your phone into fastboot mode first (turn off your phone, hold down menu button and then connect the USB cable, blue LED shall light on).

Just DON'T install it. My Xperia Arc s is locked bootloader and i tried to install Ultimate HD Rom twice, but no hope after installation Sony logo stucks!
first time i solved it by using Update Service.
second time (NOW) still on Sony logo and Update Service isn't working, it says "You already have the latest software installed"
so for now I'm searching for a way to fix it

Just SOLVED IT! :laugh:
I flashed stock firmware using flash tool
stock firmware link by a member in the forum: http://www.mediafire.com/?rhr59r4o6oarnfx
then::
1. rooted the device
2. installed CWM
3. wiped everything
4. installed UHD and choosing just one app to install
5. unticked reboot
6. wiped Dalvik Cache ONLY
7. reboot device from CWM
8. Enjoyed UHD
UHD is stock based so it will work on locked boot loader, if it doesnt then you're doing something wrongly.

Not necessarily! choosing to install all the apps in the AROMA Installer causes sticking on Sony logo in locked bootloaders.

??? To unlock your bootloader using the official method you just install the appropriate drivers and download the appropriate programs then go to the sony website and follow the instructions.
First of all, you need to open the service menu by dialing *#*#7378423#*#*
After that tap "service info" then "configuration". Look at the bottom, if it says "bootloader unlock allowed: yes" then youre good to go. But if it says "bootloader unlok allowed: no", do not even try to unlock your phone either by testpoint or official or you'll brick your phone

Please don't give false information, the bootloader is always locked when you buy a new phone. You have to unlock it manually. What you're referring to is carrier lock and not every country uses phone without carrier lock.
Flashtool can be used with a locked bootloader, the only thing you cannot do is flash a custom kernel when in fastboot mode.

Flashing kernel, Test Point unlocked

Hi everyone!
Yesterday I unlocked bootloader of my Arc, and now I'd like to flash XUK, but.. I read that phones with bootloader unlocked by Test point method can't be flashed with a .img kernel, only with .ftf. Is that true?
And if is, how can I convert boot.img -> boot.ftf to flash it with flashtool?
Thanks a lot

First time I hear this. Definitely false statement.
On side note - Boot.img can not be converted to boot.ftf. Maybe can, but not worth the time and effort.

So there's no risk flashing in fastboot on this Arc?
Tomorrow I'll try that.
Thanks a lot again.
You can't really fail with flashing kernel, as long as you got the command right. If it does return an error in fastboot, post it here and we will find the reason.
I tried to enter into fastboot, but the phone starts to charge instead of turn blue the Led. I'm a bit confused with that, because S1 Tool shows:
RUNNING S1_EROM VER "r9A021"
SOFTWARE AID: 0001
LOADER AID: 0001
FLASH ID: "002C/00B3"
LOADER VERSION: "r4A069"
SEMC SIMLOCK CERTIFICATE
The small "r" means that bootloader is unlocked.. then, why can't I enter to fastboot?
Any help?
Thanks
Just flash a kernel with fastboot. Post the log if you need more information.
I am not sure, what are you trying to say with S1.

I can't enter to fastboot, when I try it, the phone starts to charge, like phones with locked bootloader. That is what confuses me.
Phones with locked bootloaders can enter fastboot mode, but they wouldn't be able to flash a kernel. Flashing would end up with an error.
In your case, the fastboot is disabled then. 12W11 and earlier manufactured phones can have fastboot enabled via testpoint method. Others don't.

It seems that you can not unlock

The guide I followed to unlock it say that:
and my phone is "Loader version: r4A069".
I have not mentioned that I unlocked simlock with NCK code provided by my telephone company before try to unlock bootloader with the testpoint method. Actually I can use any simcard from any company and it works fine, and in theory I unlocked bootloader too.. It's very confusing can't to access to fastboot in my situation.

Which guide did you follow? Using test point method to unlock bootloader should enable fastboot as well.
Test point method would have removed the simlock anyway, could have saved some bucks if you paid for the code.

No, I didn't pay for the code. When the contract with the phone company finish, they have to give the code for free.
I don't know, I'll tray again to unlock with test point.
In attached files is the guide I followed, but it's in spanish.
Here's a similar tutorial in english, but in that says phones "unlock allowed: no" cannot be unlocked with testpoint :silly:
