unlock or locked

Hello everyone
I Bought a SE Arc several months ago. when a bought it, the seller install new firmware to support Persian language. I don't know, what does he exact do. So i am not sure he unlocked my bootloader or not. Is there any simple way to make sure my boot loader is locked or not?
I want update my phone with PC campanion, and I am afraid it brick my phone because I am not sure it is locked.
Thanks in advance.

If you have searched a little, you'd know.
There are plenty of threads about it.
And btw: *#*#7378423#*#* -> service menu.

Thank you but there is something wrong with my phone. I can't check rooting status in service menu.
I checked *#*#7378423#*#* -> service menu --->service info--->configuration
But there is no rooting status! Only IMEI,IMEI software, Available speech codec and working band. there is not " bootloader unlock allowed: yes(no)".
what's the reason?
Does PC companion recognize unlocked bootloader and update it? I mean if boot loader is unlocked and use PC companion to update it, it will update and then the phone will brick or it will not update at all and do not brick?

Afaik, PCC says it's a unknown device, when the BL is unlocked.

is my mobile bootloader already unlocked?

Hello Guys,
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.

[Q] C6506 bootloader unlock allowed: no after root?

Hey, I got a ZL C6506 directly from the Sony Store and when I got it, it said bootloader unlock allowed: yes. But now it says no after I rooted it. It's still on the stock firmware. I remember reading in another thread a while back it's just an error and the bootloader can still be unlocked or I can unroot/factory reset. Does anyone know how to fix it? Also I'm on .434 FW. Thanks!

It says no but as you mentioned its just a bug. You can still fully unlock your device without issue.

If your bootloader unlock allowed status is no then you will most likely never be able to unlock that phones bootloader. I think your best bet is to contact O2 and tell them you want a phone on which the bootloader is unlockable, perhaps they can give you a special key to unlock the functionality, but I wouldn't hold my breath.
Oh and don't try CM on it, it'll just bootloop and you'll have to use SUS or PC Companion to restore a working OS.
...actually there is one hope, but it requires dismantling the phone. There is a test-point behind the battery which might enable you to put the device into a mode where it'll accept a command allowing bootloader unlock. But again, high risk, not sure if it's actually possible, easier to just sell the phone and buy an unlockable one if you want to run CM. Maybe you could even return the device, how long have you had it?

my z1c just turned up and ive got an bootloader unlock allowed :victory::victory::victory:

I have locked bootloader on EE in UK and have found that many of the tweaks I wanted can be achieved with Xposed modules. Give it a try but backup before you start.

Need a opinion by a dev
Hello there,
I was thinking about a test.
My problem is "Unlock bootloader allowed : no".
What could happen if i restore an other TA partition with "Unlock bootloader allowed : yes". I erase the old by a new one which unlockable. All i need is a TA partition build with a z1c which unlockable and the unlock code.
What do you think ?
Soory for my bad english

If you replace your ta partition it will most likely hardbrick your device.

What is a ta partition, i don't understand.
A bootloader is like a bios on motherboard.
But it is locked by a code.
The bootloader is the same on each z1c no ?

Flashing another phone's TA will hard brick yours, every TA is related to the phone which comes from

How you done this??? I tried hundred and half methods and still CAN'T unlock damn bootloader............

Why can't I unlock my boot loader

I thought I've had this device nearly 2 years now so time to unlock and root as the custom ROMs are looking great.
But if I go on Sony page and enter my details to unlock my bootloader it informs me my device is not unlockable.
What are my other options?

Simply means your device is not unlockable. That's it. I'm guessing you got this through a phone carrier.

Yep through Vodafone, so is there no other option

Nope. It's done. Bootloader can't be unlocked at all. Even if you try to unlock bootloader anyway using flashtool, it will ask you to enter unlock key, which you can obtain only through sony website.

Thanks for your help maybe I should just upgrade to a new phone then only reason kept it stock was for warranty
