Can we unlock the GS2¿ - AT&T Samsung Galaxy S II SGH-I777

Can we unlock the. ATT Galaxy S 2 using the unlock app?
Sent from my GT-I9000 using XDA Premium App

Same question here. Mine will get here on Tuesday...I do know there are a bunch of methods to sim unlock i9100 though.

So... long story short, the GS2 still uses nv_data.bin files like on the GS1.
Of course, Samsung has encrypted/obscured plain text access to the unlock codes within this binary file. However, I do believe the folks over on the i9100 forum have figured it out, so it's probably not going to be too much of a stretch to get the AT&T GS2 to work too.
The phone literally just dropped though, so give people a few days to actually get the devices in their hands, get nice stable root and all that (already done maybe even), and from there, carrier unlock will come.
Or, if you're the impatient type, and don't mind the chance of screwing something up, try some of the methods from the i9100 forum and see if they work!

I used the galaxy s unlock app from helroz, worked like a charm. Can't post a link but it's on the market.

That's awesome. May I ask whether you had rooted your S2 before you ran the unlock program?
Thanks a billion.

Yup, rooting is required to unlock.

Sorry, I'm fairly new to the term "unlocking" phones. Does this mean that you can use with any carrier? Is there anything else that "unlocking" a phone does that a normal one can not?
Thanks in advance!

Thinking of purchasing this phone

I just sold my Wildfire Buzz, which I successfully rooted.
Soo I think the ACE is logical and cheap upgrade for me.
Just wondering if I root this phone will it unlocked (from the three network)too or is that something separate?
And is their anything I should look in regards to this mobile?

Seriously, it's a very good handset,with a growing dev community. Worth to buy on my opinion.
Ah,no troubles after rooting, it will be simply more powerful!

Nothing changes on network side....
Just beware not to grant network access to any app to avoid unwanted network connections. Also use apn droid widget which will switch off any connection.

He is asking if you can unlock the phone from Three network. I believe you have to buy an unlock code though, have seen people bricking trying to use a root app to unlock.

Carrier unlock WITHOUT rooting

I would like to carrier unlock my SGS3 without rooting it. Is there a way to do so? I am willing to pay for such a service.
I will buy the phone from Comviq (Tele2) in Sweden.
Anyone who have tried one of those online services where you buy an unlock code?
Code will work but Rooting is easy
[QUOlebp;30607435]Code will work but Rooting is easy [/QUOTE]
I know rooting is easy but I don't want you do it. I have to unlock it "legaly"
Is there a tested website that we know work?
Thanks.
Legally ask network to unlock it .

They won't. You need to have the phone at least a year before they give you the code. Does anyone know a trusted website where you can unlock the international SGS3?
BTW! Can someone give me the link to "rooting method" carrier unlock? I might just root it if I can't find a trusteed website.

Hi! I'm thinking about getting myself an Galaxy S3, but the one I've been offered is locked to another swedish carrier. I'm using Telia and the phone is locked to "3".
Is there a great carrier unlock-software with minor (or no at all) bugs or required reboots? I'm also thinking about installing Cyanogenmod or another Custom ROM to it..
Is this the one and only great solution that fits me the best?

Sorry but that is the best I can find. Although this doesnt look too difficult. The codes on the phone seem to be better encripted than on other phones so therefore software isnt an option.
Try phoning the carrier you are locked on even if it wasn't your contract and see what they can offer you! 3 Seem to be better about unlocking than other carriers as they are based in the uk they are required by law.
hope this helps

Peoples should stop to use this fix that may be dangerous in some case
Better to stick with GalaxSim Unlock for now
It really isnt because if there are any problems you can replace the old files and in an extreme case you can reflash your phone!

[GUIDE] free sim unlock for i717!!

firstly you need to flash the tmobile based ics modem ( flash in cwm or twrp) found here:
http://multiupload.biz/fdpnprq0ov6o/Official TMo ICS RADIO_NOTE_MultiUpload.biz.zip.html
then after flashing boot into your rom and follow these instructions exactly (note: after pressing perso shaf256 off I had to press back twice instead of once, but then I was back on the network page and could choose [4] NW LOCK NV DATA INITIALLIZ):

Can't wait to try this on my Bell Note! I'm going to Florida soon and have been procrastinating on getting the phone unlocked...
Score one for procastination!
I was surprised when it actually worked... I got screwed out of an unlock code by an online company (only 8 bucks but still) so when I saw the t989 modem and thread about free unlock for their phone (using the same modem you can flash on ours) I had to try it! I flashed a rogers radio afterward and the unlock stayed also.
Thanks for posting! I'll definitely be trying this out when my Note arrives on Saturday.
Worked perfectly!
I am impressed! I worked like a charm in the very first try! I used a AT&T Galaxy Note I717 with stock ROM (I717UCLF6, kernel 3.0.8). The best part is that later I flashed another ROM (Padawan) and it remained unlocked. Did a couple of phone calls and it is working great! Thank you so much! :victory:
you're quite welcome guys! Figured I had to share the wealth on this one and hopefully save some users some cash and/or getting scammed by too good to be true unlock code site "deals".
Got my note unlocked for $3 but I will pass this method on.
Thanks.

The Note has been out for a while. Is there any reason not to simply call ATT (or whatever carrier you have) and ask them for the unlock code? Don't get me wrong. If this method is safe and if it works, then thank you for sharing.
can anyone verify this does work on at&t? and do we just reflash an at&t modem after its done?
thanks

it will work on any variant, has to be an ics rom though, just flash your normal radio back immediately afterwards.

Just curious, where did you get yours unlocked for $3. I'll use it as a last resort. I plan on web chatting with ATT first and try my luck that way. I don't have cell service with them, but I do have home phone service.

Of course. What was I thinking? However, are the other carriers much different? Can't you just request the unlock code from them?

Sorry, Crixley. I think your post is appreciated, and though I wasn't terribly excited at first, I did thank you. I forgot to push the Thanks button but that's taken care of now. I wasn't sold at first that this unlock would work but it appears to be valid for several users. And, being an ATT user for many years, I can get my unlock with a simple phone call. However, I see your post as very valuable for many others. So, THANKS!

Benifets of unlocking?

So I just unlocked my phone and was wondering the benifets. I know that I can use other networks like ATT Rogers Bell etc. But can someone explain in detail what I can do?

That is all you can do when you "unlock" your phone. You remove sim card based carrier restrictions. Once unlocked you can take an att phone and put in a tmobile sim and it might work! But that's all it can do.
You might be thinking of giving your phone "root access" if you want to do more. Once you root a phone you can remove preinstalled software or bloat. You can install custom roms. You can enable tethering when you might not of before... and so on.....
Rooting and unlocking are two different things. I hope this answers your question.

I figured you knew what rooting was because you have a decent amount of posts. I just wrote it so anyone uneducated would understand a lil better.

What true is it!!!

I just got another mega, this time I got a Att version. I spoke with a customer service rep. and got my unlocked code bcuz I purchased full price, I ask her about bloats ect ect. Ok this is what she told me, once I have unlocked my phone I have full control of my phone.. Hmmm really? I dont know if she knew what i was talking about.. then I ask about secure bootlock portion of the phone, she reply once your unlocked you could do what ever you want...:what:
I have the unlocked code, how would i unlock the darn thing? every phone is different ways to do it.
I want to know if its true or not that once unlocked we can do what ever including custom rom...

What I think you got from her was the network unlock code, all that does is allow you to move to another provider using the same phone.
So whats the difference between network unlock and phone unlock?

Network unlock is as above ^, the bootlock you mentioned in your first post is there to stop you removing their software, it's not something that you can change with a code. You need to remove the boot lock before you can replace the os with a custom one. Before you attempt to do anything like this I advise reading up on it, you don't want to brick another phone. The information is easily found by using google search.
Roger that..lol yeap I dont want to do that again..

No boot unlock yet so no custom recovery or custom ROMs.
I am talking about the I527 btw!
