[Q] bootloader status

How Do I find out the bootloader status (Locked/unlocked ?) of my xperia ARC.
actually I unlocked it official way, then relocked and updated to .42 fw using PC for giving to repair under warrenty. its over and I want to unlock bootloader again. whats the best way I'm on fw .42 baseband 56.
thanks a lot in advance.

dial from your phone to check status :
*#*#7378423#*#*
service info --> configuration
for me, the best way is via fastboot..

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 "

that means your bootloader is still locked, and you were allowed to unlock it.

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.

Yes, you can unlock again.
Request the code again and you'll see if they provide it again.

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.

For the info...
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

[Q] Can i still send for repair?

i wanna send my arc to change the housing as it been found and kind of damage... but the software is running on stock unlock bootloader with doom kernel... should i flash back to the stock kernel and lock the bootloader before senting it to?

Would say yes, but it depends on how they unlocked the bootloader as this can void warranty ......
Also how much damage has been done its it really necessary to send for repair.
Is it possible to phone Sony service centre and explain what has happened and seek there advice on next options.

I sent mine back in the UK with a custom kernel and rom also with bootloader unlocked. It came back with the cracks fixed and an official software installed.

Unofficial way to unlock bootloader xperia s

is there a way to unlock unofficially the bootloader ?

Why would you need to Unlock Bootloader Unofficially? You can unlock your Bootloader officially from HERE.

You lose the warranty if you UNLOCK your bootloader, officially or unofficially. But you can always relock the bootloader if you want to keep warranty.. Refer here http://forum.xda-developers.com/showpost.php?p=23188292&postcount=2

I don t think you will keep the warranty, relocking bootloader, because is an unofficial way.

I like so much to read perfect people...
Every person who has unallowed unlockable bootloader have no other option than to look for an unofficial way... so the question about this it's pure hypocrisys.
For now does not appear to exist a solution...

What did you want to say ? I've only asked something that I was curious to know, because I don't want to lose warranty to flash an AOSP ROM. Samsung is easy to mod .. I miss my old phone

Just a note about the warranty. Unlocking your bootloader will NOT void your warranty. Yes Sony will know if you unlock and you will lose drm keys. Sony will still honor warranty for bad parts and workmanship. However if it's unlocked they will be more picky about claims. Say your phone unlocked with custom kernel and have overclocked. If you cook the cpu by running to hot, that is your fault and Sony won't cover. But say you get some yellow tint (like XS got) in screen Sony will repair.

Re-locking should have no effect on warranty. It might however allow the use of pc companion again.
From the Sony developer website for unlocking bootloader
Technically Sony says this...
Notice the MAY void warranty. Not WILL or AUTOMATICALLY or ABSOLUTELY voids warranty.

People who have bl unlock allowed: NO
Will obvious need an unofficial way to unlock bl.
As far as I know, no news about that... unfortunately

Well, usually once you unlock the boot-loader you lose the DRM keys with no DRM keys you have no warranty. Therefore yes Sony will detect it was unlocked once, and refuse warranty upon those grounds.
There is methods to unlock without losing the DRM keys but I've not looked into them too much.

Bootloader unlock allowed:NO!!!

I originally had an xperia c1905 but cross flashed c2005 FW onto my device. What i find really annoying is that when i open the configuration in the service menu i find out that i cannot unlock the bootloader, ie, bootloader unlock allowed no. I haver read online and i have researched it, but other posts were made in 2013, i thought id ask ahain in 2014. Is there any possible way whatsoever of unlocking my phone's bootloader? will i ever be able to do it? Are there any modern ways that i might have missed?
Guys please dont tell me to send my phone to sony and they will unlock it for me. I have already tried it, but fot no response from sony. I have even contacted o2( my sim carrier) and asked about information on how to unlock, they told me that they cannot comment on that subject.:banghead::banghead::banghead::banghead::banghead::banghead::banghead:
If u have any information, i need your help, thank you!

As far as I know, no way of unlocking your bootloader if it says no. You still can try the regular bootloader unlocking procedure method, the only thing that may occur is it not working...

Or it can brick the device just leave it for now and wait for the time being there might be a way of doing it if it gets found if not the new firmware that's getting released shortly might lift the ban off the bootloader

I have the same problem. Please somebody need to find a way to unlock it. I bought my phone from Orange. I flashed the stock Sony's firmware and rooted it. I can't flash any CyanogenMod :crying: My old Galaxy Ace hasn't got any locks or something, installing custom roms was easy, but on this phone for me it's almost imposible...

I stumbled on a post on the Sony Talk forums the other day that stated if you carrier unlock your phone (so you can use any SIM card) and then flash an unbranded ROM the bootloader unlock status changes from No to Yes. This statement was made by a moderator on the forums and I have no idea how well the procedure will work.
Oh, the post was regarding the Z too so I'm not sure if it applies to the M.
