Hey guys. So I finally got my SGS back from Bell again (This is my 2nd replacement). Right away I got to work to unlock it. However, it seems that Bell has changed how unlocking works again. I recall when I got my first replacement, I could not unlock it. I could get the network control key (aka the "unlock code") using the SGS Unlock apk, but the phone would not accept this as a valid code. Instead, I was able to relock the phone to my carrier by changing the MCC/MNC code, and then entering the network control key. This worked perfectly.
This method does not to seem to work on my new replacement, however. Using the SGS Unlock and the generate unlock script, both can not seem to find the nv_data.bin file. As a result, I do not get an unlock code of any sort.
I've also attempted to downgrade my phone, but flashing JH2 with Odin puts my phone in a boot loop. Should I try another 2.1 ROM?
In the worst case, is it possible that Bell has been replacing phones with totally non-unlockable phones?
I'm at my wit's end as to what to try next. Any suggestions?
Greetings...Assuming you have rooted your phone, use SGS unlock from the market and you will need to install busy box as well.
That's what I used for my JL2 build and it worked.

Is busy box absolutely necessary? I had installed Darky's rom, so I had root+super user, but I'm not sure if I had busy box.
I had also tried to use the app to generate root codes, but it gave me the same error; no code found.

Rooted my phone and have busybox installed (I forgot that SuperUser = busy box).
Tried the apps from the market, didn't work.
When did you get your phone? Did you buy it new from Bell or was it a replacement?
edit: OKAY FORGET EVERYTHING I SAID
I figured it out.
This what I did:
1) http://forum.xda-developers.com/showthread.php?t=803682
I used this application to root my phone.
2) Restarted my phone (I tried to unlock without restarting, it didn't work.)
3) http://www.androlib.com/android.application.com-helroz-galaxysunlock-zxpBC.aspx
I then used this application to unlock. Remember to back up your EFS before doing anything.
4) I entered *#7465625# on the phone to verify the unlock.
I hope this helps anyone else who had the same problem as me.
Thanks a lot guys!
Codes often don't work on the new i9000m revisions. Use the nv_data hexedit method, changing 01 to 00, as can be found elsewhere in the forums.
Read around, your solution is out there already.
Best to do these things manually instead of with an automatic tool imo - only takes a few minutes longer, and then you'll actually understand the process.

Hi xda,
Before i purchase my Captivate from Rogers, im wondering if its possible to unlock the phone. Reason for this is because im with Fido, and i need the phone unlocked to use it.
I'm just wondering if there is anyone out there who unlocked their Rogers Captivate.
Many thanks,
Kon

Has anyone tried it??
I have tried a couple different ways. Nothing seems to be working for the I896
I have as well and can't seem to do it I paid for an unlock code as well but doesn't seem to work.although I haven't tried with a sim card in yet.things aren't looking so good... Theres another method on here for a permanent unlock but I'm leary on trying that yet, I've skimmed the phone trying to find anything and nothing too promising.

This phone works on rogers/fido. Rogers lock their phones on all carriers except fido because it's their child company. I've been using it on fido since launch day 2 weeks ago.

I am using this phone (from Rogers) on Fido. However i still want to unlock it since i travel a bit and want to use local companies too...
Anyone managed to unlock it??? do the "pay" websites really unlock it or are they scams?

Just unlocked mine. First had to root it then used universal SIM unlock method by miztaken1312 (sorry, can't post the link yet).
The one click unlock will NOT work, Rogers cleaned up their firmware, so the unlock code is no longer stored on the phone itself. However, miztaken1312 method modifies one of the system files on the phone to store the unlock code of your choice. Basically, after you set up ADB and root your phone you download a special system file from the phone, patch it using special online utility, upload the modified file back to the phone and now you know the unlock code.
Update: in case someone is still looking for info on how to unlock Rogers Samsung Galaxy S Captivate SGH-I896, here's the link to the site I used: http://www.communityhosting.net/sgsunlock/
Root your phone first with z4root app from the market, then backup and make sure to follow these steps carefully!
I bought Captivate by paying all the equipment cost because AT&T told me that they will unlock it whenever I will have to go out of US. They did give me the code but it did not work. After 2 days when I called customer care and they said they dont have the code, but when I told them that I was given the unlock code 2 days back they asked me to spell out the code and then they said yes it is the code. I tried the code with the customer care but it did not work. Then I tried the method showed on youtube (generate_codes.bat, sgux.exe) but I get the

I see my 550$ going waste Please HELP!
I have already tried 8 times and there are only 2 attempts left. Please help else I will lose all my money becaues I do not reside in US and I need to use this phone in my country.
Thanks
Have you done any ROM flashing?

if you haven't flashed any ROMs, here is what you can do. go to market then search for SGS unlock, install and run it, it'll give you the code. thats how i unlocked mine. write the both codes down just in case.
No I have done nothing. It is just 6 weeks old phone. Same as what was delivered by AT&T. I did not play around with anything (like rooting, or installing beta Froyo)

try dial *2767*3855# the phone will hard reset, then try it again. i didnt have any problems unlocking my phone by using SGS unlock, have flashed some stock ROMs in the past few days and didnt have issue at all.
I think the JH7 update screwed up the easy retrieval of the unlock code.
http://forum.xda-developers.com/showthread.php?t=789888
There's some info about a possible work around in there, but the guy who came up with it is apparently French and the translation to English is a little rough.
and to the OP ... my code was all numeric, so not sure why you would have had to 'spell' it to the AT&T rep.

if you have not done anything on it, i'm assuning that you haven't rooted it yet. if thats the case, get z4root from market and root your phone. then use SGS unlock to get code, choose root-code option.
It is possible that your nv_data.bin is encrypted - the only way to know is to root the phone, and view it with a hex editor. If it is encrypted, there is a web tool posted in the dev section (search 2.2 unlock) that will take the nv_data.bin and rebuild it with whatever unlock code you want.
Did you upgrade to Update1 from AT&T? I did software update from phone and it updated the version 2.1 Update1.
I have tried it after doing the upgrade and SGS Unlocker is not working.
What does hard-reset mean? Does it mean "Restor to Factory Defaults"? If yes, I can do it through standard menu entry in settings? Is this different from the method you gave? Will hard-reset reset the 10-maximum-attempts-to-unlock counter?
Thanks for replying!
No. I have not done any ROM flashing.

hard reset = master clear on odin. it wipes out everything on your phone even SDcard. it is different to the standard menu factory rest. and i'm not sure if it'll reset the 10 max counter though.

Since there are only 2 attempts left for me to unlock Captivate, what will happen if I exhaust all 10 tries? I read somewhere that it will hard-lock or freeze. Can this hard-lock be reversed? Is freeze unlock code used to reset the counter?

If it does hard lock? Then you would need to take it to an AT&T shop.
Have you tried CLShortFuse's one-click root program? I haven't tried the Captivate unlock feature - but my guess is it should give you the unlock code.
You can get it here.
I have the same software on my phone as the OP. I got the phone unlocked by using the root method of SGS. Now how did I root the phone? Someone recommended the one click root method found inside the One Click Lag Fix found in the market.
So, to recap. I got the One Click Lag Fix app. Used the one click root method. Got the phone rooted (it is a couple of steps actually - you still have to update on recovery). Now that you have superuser status, used the SGS app to search unlock code using the rooted phone method. It will show the unlock code (mine had 8 numbers). Hope this helps.
PS: For anyone reading this, AT&T DOES NOT have the unlock codes yet. Any rep that promises that you will be getting an unlock code soon is not really telling the whole truth. All it shows on their side is that unlock codes unavailable but it does not shows when they will become available. I think I read somewhere that there is a 10 months exclusivity on the Captivate (starting when it first came to AT&T, which is this last July).

One more time - this is from experience:
If the nv_data.bin file is encrypted and unlock code doesn't work or can't be found you need to rebuild the nv_data.bin file. Period.
There are instructions in the Dev section under a thread titled 2.2 unlock.
If you use all 10 attempts - the phone needs to be sent to a service center to do a low level restore - usually Samsung not AT&T.
Quick question about unlocking a phone. I used the sgs unlock tool and successfully retrieved the unlock/unfreeze codes (and have them saved on my computer) but not sure what to do now. Going to be flashing a new rom on this phone for the first time and I'm not sure if is should grab a t mobile sim card now and try to unlock it. Or will flashing a new rom mess up the unlock so I should use a t mobile sim after the new flash. And if so, will the unlock reset every time I one-click back to stock and flash a new rom? or is the unlock deeper than the roms and will save itself?
Also do I need to backup the NV_data files. I have read a lot and this still seems pretty confusing for me.
BTW this is a friends captivate, I've been flashing mine for months and I need to go through that whole huge process to repair my NV_data stuff to get my codes again. Which is another question I'll have work on later.
Thanks..
Shane

Put in your tmo sim card and it will ask you for the unlock code. Enter it and your phone should be unlocked. And once you unlock it it should stay that way.
will give it a shot. thanks.
Hi,
firstly i understand that everyone is quite picky about using the search function to first find relevant posts. However i have gone through an immense amount of posts and still am unable to unlock my SGS.
I have the UK version
Samsung galaxy s i9000
locked to orange
i tried unlocking using the tool from:
http://forum.xda-developers.com/showthread.php?t=761045
the error i get is shown below:
Uploaded with ImageShack.us
my mobile is rooted using latest docs rom.
Also as i couldn't get this to work i purchased unlock code from eBay for 15 euros however they also refunded saying they couldn't find the unlock code.
I can't access the android market to install the 'pro app' because i don't have an orange sim card.
help would be greatly appreciated
I've done some searching myself, not so long ago, and apparently you need to flash your Galaxy S back to the stock rom it shipped with before using that tool!
I can't confirm it though, didn't try it myself.
Or try using Market Enabler to fake the identity of your phone to the market so you can access all the apps in the Market. There's a free app called Galaxy_S Unlock that I and some people had success with, read it's description first though and just do the steps in order.
Goodluck!
I found this great forum a few days ago and after a lot of reading I have managed to root the phone and install a few apps.
I have also been able to backup my efs folder and edit the nv_data.bin file using a hex editor as per this thread here http://forum.xda-developers.com/showthread.php?t=761045.
However after changing the byte 01 to 00 at line 0018146 8 and reloading the file to my phone, it is still asking me for an unlock code
when I put a new sim card in. I have the Galaxy S running GingerBread 2.3.6, Baseband I9000 XXJW4. I have also tried the unlocker softwares posted elsewhere on the forum with no success. Is it possible that anyone can give me pointers on how to successfully unlock the phone please or suggest where I may be going wrong.
i don´t know, if i unterstood you right, but last year i got a new sim card, which is locked by a code by the provider (of course they told me this code). Every time i restart my phone (unless it´s in airplane mode) i have to tipe this code. So maybe in your case it is also the sim card, which is locken and not the phone..
Thanks for the quick reply, but it can't be the sim as it's on Pay As You Go in the U.K and so not a contract sim.
Did you try with Samsung Galaxy S Unlock Tool or SGS Unlock PRO?, it's on the play store i unlook mi phone with it.
Hi,
If i'm understanding you right you are asked for unlock code in the phone startup,
If that is the case i once experience the same problem with my phone and i fix it by typing the wrong codes some times untill the possible retryes are over after that my phone continue to load the OS and after that i never met the problem.
Regards,

Normal USIM unlock code is 0000, if failed you can try the unlock tools on MY android collections link below
Once again thanks for all the replies.
I have tried the 0000 code which failed with a message that network unlock was unsuccessful. I haven't tried any other code because of the 3 strikes and phone barred conditions.

I have also tried the 'Generate Windows Unlock' tool but it seems that the graphics card in both my laptop and desktop is not compatible with the software. I have also tried the SGS Unlock tool as well as the free one from Helroz but failed to unlock the phone. The tool from Helroz successfully changed the relevant bytes according to the software, but when I rebooted the phone it was stuck on the Samsung Galaxy S start screen so I had to re-flash the software and restore the backup of my efs folder.
I have not tried the paid for tool from the market as, being a 68yr old complete newbie to the smart phone era and not yet having a wireless router, I am unsure as to how to get it. To give you some idea of the leap I have made with this phone, which was given to me by my son who has now emigrated to Australia, my current phone is an old Nokia 5110 which I have used for around 12 years.
Thanks for your help and patience.
I have now managed to unlock the phone using SGS Unlock Pro with the generic unlock option, for some reason the Samsung unlock option kept crashing. Thanks for the tip with the Pro version of the software and it seems that I have a lot to learn regarding this phone, now for a different ringtone.:good:
