Try this: http://m.wikihow.com/Unlock-Samsung-Galaxy-S-II-(S2)

That isn't helping, I found this already on my own. But thanks.
It must be "FREE" the method of unlock code or else I can take it anyway to a phone shop...

unlocked phone relocked by HTC repair

Hello -
Having had my 1.76 Hero unlocked (£20) to allow vodafone use, it now has to go into HTC to repair a broken g-sensor. It will come back locked to t-mobile again, with upgraded t-mobile ROM.
I intend to replace the Rom anyway, with Modaco custom ROM.
So do I need to unlock it all over again (I don't have a t-mobile sim card), or is there a way to go directly to the ROM flashing?
thanks,
alex
Do you have the option to input an unlock code?

In this case, I suggest you'll need an golden card. Search for it using the searching function.
Good luck.

Edit: Just trying to help. Sorry for my poor english and knowledge.
I myself never tried a gold card before so I'm not sure how it work. I'll have a look at everything I'm going to mention next time.

He isn't asking about rooting, instead of spamming every post in the forum with answers maybe just dont assume he wants something he didnt ask for?
you have even contradicted your post saying he needs a gold card in the last post!

You have to unlock bootloader in order to do that. Read the thread about SE tweaker tool in the mini/pro development section also check out xxxlordxxx's thread about his one click tool.

AFAIK, no...
There exists two kind of locks,
SIM Locks (that lock the carrier), there is no free way to do this.
Cheaper way I found is the one unlock credit from Omnius, but you will be unable to unlock the bootloader. Same thing happens with several "unlock by software" methods. Read about it before unlocking if you plan to flash CM7 anyway after unlocking
BootLoader Lock, that prevents from replacing the kernel... It's free to unlock. And changing the kernel is required for the unofficial CM7.
Be careful because some unlocks work by patching the firmware, so upgrading it would sim relock.

Well, the device was bought from Vivo carrier, which said the device was unlocked, but I was not able to use sim card from Tim carrier. After flashing miniCM7 it is working. Maybe was a coincidence or bad contact between SIM card and the device. I have no idea how to clarify this now...

When you inserted the other carrier sim, and restarted the phone, did it asked for the unlocking pin code? Did you restart the phone? sim cards can't be hot plugged.

I've sim-unlocked my phone just by using SE updater and updating software from 1.6 to 2.1. Phone was locked to Telenor Serbia. So, what kind of lock was it?
Sent from my U20i using XDA App
It is possibility to unnlock via unlocking bootloader. My phone was locked on tele2. And after i unlock now my phone is sim unlocked. I already try to put in sim cards of other mobile networks.

Thanks a lot for the reply, very informative. I would probably use a paid service but since i bought these phones for 20 eur each, it's almost the price of the phone to unlock it, not really worth it.
Can you expand on BootLoader Lock? I though it did not do that, from this thread: http://forum.xda-developers.com/showthread.php?t=1254225 third myth says it does not do that. what gives
tried this: unlockbootloader sonymobile com / instructions but my phones don't have the Bootloader Status parameter, guess I'm SOL

Unlock by code without locked simcard?

I have the code to unlock my Xperia S, got it for free from my provider
But I do not have an "locked" sim card.
How do I enter the code then?
Just pop in any other SIM and it'll ask you to enter the unlock code.

Damn.. I want to unlock my bootloader now.
Or, if you must unlock it now, go ask someone who has another provider for their SIM for a few seconds.
problem solved. Next time post this in the Q&A section.

Yes that would be a solution, but it makes it alittle harder to get hold of a micro sim..
Oh sorry, tought that was like a FAQ section. Maybe a mod could move it?
You won't be unlocking the bootloader I don't think, just the sim lock on the phone.

Sim unlocking the phone doesn't seem to have anything to do with the bootloader unlock. And if you don't have another SIM card, then you probably don't have to even SIM unlock your phone in the first place.
There are some users on this forum which claimed SIM unlocking the phone will get rid of the bootloader lock as well. I have unlocked my phone, and have proven this to be false. Strangely, whenever I questioned the users for their proof they never posted it.

You are right. I don't actually need to remove the sim lock. But I read somewhere that the bootloader became unlockable when the sim lock was removed.
But if that wasn't true for you, it probably won't be for me neither..
Doing a SIM unlock will not unlock the bootloader. Both are unrelated. As long as there isn't a test point method you will not be able to unlock the bootloader.

Can I still sim unlock my s2 if I'm running a custom rom?

Hi,
I wonder if anyone knows if running a custom rom on the S2 would stop me being able to sim unlock it?
Thanks

Why?
IMO doesn't make a difference for unlocking ... only if it is a special feature of the custom ROM to prevent SIM unlock.
Read the descritption of the custom ROM, and if there is nothing about it, it should behave like stock ROM for unlocking.
P.S.: If you want to unlock your phone, why don't you unlock it before flashing the custom ROM?

Hi, thanks for the reply.
Basically I have sold phone and the person who bought it tried to take it to a high street unlocker and they couldn't do it because it was running a custom rom.

ok, as far as i know you can remove the SIM lock by entering a network/SIM unlock code. You can usually get one from your provider. You have to pay them of course... :crying:
I know that german T-Mobile phones can be unlocked that way, not sure if its the same in Austria...
Removing the SIM lock does not affect the status of your bootloader! If its locked it will stay locked.

Thank you stothegee, I really apreciate your help!
I have been looking for a topic about it in T-Mobile website and I didn't find nothing good.
In the meanwhile I found this service:
cellfservices com => "unlock-sony-st27i" (I can't post links yet)
Do you know it? I would like to know if it's reliable or not.
Thank you for the help
