[Q] have unlock/unfreeze code, now what? - Captivate Q&A, Help & Troubleshooting

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.

[Q] Unable to unlock captivate

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
failed to copy '/efs/nv_data.bin' to './nv_data.bin': Permission denied
Error: unable to find file nv_data.bin>
Phone details: Firmware 2.1Update1
Baseband ver: I897UCJH7
Kernel 2.6.29
Build #: ECLAIR.UCJH7
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.

I accidentally deleted my esf folder when unlocking....help?

ok, so i get home to flash new serendipty. I did a wipe and flashed the rom but forgot to back up the esf folder even though the program drilled in my head I needed to. Ok so now I assume its gone, heres my question.
does it matter, and how will me not having this file backed up affect me?
Thanks everybody
I also master cleared.....I just would like to know If Im ever even going to need the code again, im not returning the phone to att ever, I dont think so. It seems to be working fine with my t-mobile sim card as well as the att one.
If for some reason I get another sim card, from another carrier im worried I would be prompted for unlock code, which I wouldnt be able to retrieve because I deleted the file...but then wouldnt I just be able to unlock without the code again like I did the first time?
I had used galaxy s unlock and I never got the code, it just followed the steps and rebooted the phone and voila.
thnanks for your time everyone
Use sgs.tools app, secret codes, check your ime and product code. I have never backed up my efs. You should be fine
really appreciate it, thank you
now what is the difference in my unlock rather than a straight up enter the code unlock. As I said I used galaxy s unlocker so I never had to enter a code, but wanted to do it that way, but instead bypassed it completely.
Im just curious as to how exactly does this work? and whether its a "real" unlock or rather just tricking the phone.
I entered the keys to check gsm lock and it is off, however im just wondering
anything else I should know about the esf folder?

New JL2 Bell i9000M not unlockable?

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.
Sent from my GT-I9000 using XDA App
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.

Galaxy S GT-I9000 unlock help please

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:

[Q] Unable to unlock phone

So, basically, I got a new pay-as-you-go SIM and I don't want to buy a new phone for it. I was looking for methods to unlock my current galaxy ace, it's rooted and I have a custom ROM on it- The Ultimatum by The "A" Factor. I got my unlock codes and put the SIM in expecting to get a screen saying phone is locked, please put in unlock code or something similar that usually happens. However nothing came up but when the phone finished booting, I had no service and can't use it for calls or anything which suggests that the phone is still locked, I tried using the *#7465525# service code, but I got an error saying no service or incorrect MUDI code or something like that. Is it possible that flashing a new ROM wiped the unlocking procedures and is there anyway for me to know if my phone is unlocked and if not, can I still unlock it?

Didn't show you nothing to introduce the code?¿
... try introducing another SIM from other carrier... when you boot then automatically should ask you to introduce the unlock code
If it doesn't work you could phone to the device's carrier, the carrier must help you if you finished your contract

I do have another SIM from another carrier, but the screen isn't showing up, I've been scouring the internet and found http://forum.xda-developers.com/showthread.php?t=1335548 , turns out it won't show because of my ROM, so I'll have to switch to stock like you said, before I do that though I'll try that code he said at the end to see if it will unlock.
