Hey sounds like you're trying the hard way. Can you try the easy way first and see if that works.

Anyone know how to change the title of a thread on this forum? This unlock method is now confirmed by a ton of people.

try double clicking on the thread name in the main forum page. dunno if it'll work but that's how some forums have it.

Yes then you do need the sdcard

Dumb question: anyone know what the original MNC / carrier lock code was there originally? In case it's gotta be sent back, warranty exch, etc...

The Code is below. The Mac version of The Galaxy S Unlocker was made by NBS11. This method of obtaining the unlock code was found by dagentooboy. Also thanks to bowsa2511 for helping make the script. Donate links for them can be found on the XDA forum link below. Please remember to donate to me like this program at http://bit.ly/cplmLk (paypal only).

Your code is:

Guide to entering code:
1. Power off phone, 2. Put in other carriers SIM, 3. Turn on phone, 4. Enter unlock code. BE EXTRA CAREFUL; ENTERING IT WRONG ONCE WILL BRICK YOUR PHONE, 5. You are now unlocked. Congratulations.
If you need any help go here: http://forum.xda-developers.com/showthread.php?t=761751
Also, if the unlock code doesn't work and it freezes your SIM, enter this code:

rm: ./nv_data.bin: No such file or directory
logout

[Process completed]

this keeps happening what's wrong?

Search the market for Captivate Unlocker. There's a free application apparently which should work.

lordhamster · Sep 10, 2010

Sgs unlocker from the market is free and works great. It even emails you your code. I used it and it worked 100%

Cake He · Oct 5, 2010

I followed your youtube video to unlock my AT&T Captivate (unrooted). When I run the Generate_code.bat, I got the error messages:

failed to copy '/efs/nv_data.bin' to './nv_data.bin'

ermission denied

What I did is:
1) downloaded Captivate drivers and installed it.
2) connected phone with PC (with USB debugging checked)
3) downloaded and unzipped the unlock files, and run the .bat file.

Anything wrong? Thanks!

You're doing it the hard way. As said in this thread multiple times now, use the SGS Unlocker app.

mui · Oct 5, 2010

It looks like he's using JH7 where they locked the permissions of nv_data. SGS Unlocker (currently) no longer works in that case. You can find a manual way using grep somewhere in XDA Captivate General forum.

If you're using the JI6 Froyo, you're SOL. They scrubbed the plain text unlock code from what I understand.

Hmm you're right. I hadn't noticed this. Updated CapFAQ.com. If there's a manual way via grep I'd hope he could update the tool.

Unlocking isn't important to me except for increasing the resale value somewhere down the line. But that's a ways off. Guess I should've written down my unlock code before updating to JH7.

Andrewdroid · Oct 5, 2010

Unfortunately, the easy-peasy SGS unlocker app doesn't work after the Captivate OTA update in october. This is confirmed by myself and loads of other comments on the App site. HOWEVER, if like me you unlocked your phone BEFORE the OTA update using the code the app provided, (you should still have the code saved on ur phone's internal SD card), then the unlock should still be working.

To check,and make sure that Network Lock is the only thing on... go to phone and enter *#7465625#

PS. I've included a link to xda about the code, so don't just type in random codes in your phone if the original poster doesn't know what he is saying because there is at least one code that resets and formats EVERYTHING and luckily I had backed up my phone after using that code on the advice of just one poster on here.

Not entirely true. I unlocked my phone right away, but after the update the unlock programs no longer work. My phone is still unlocked and I wrote down the code, so I am not worried, but I definitely cannot extract the code anymore.

dmp316 · Oct 5, 2010

Wow thanks for the heads up. My question is if this is done will 2.2 still work?

Cake He · Oct 5, 2010

Yes, Mul might be correct. I just got my new Captivate, which comes with JH7 update. It seems that SGS unlock method does not work on it. Any other methods?

Whoa whoa whoa what now?

Yes, if you unlock your phone then you can still upgrade to froyo

If you're desperate for the unlock code you can downgrade to jf6 first http://www.thevod.org/misc/captivate/I897UCJF6-final-OCD-REV0.rar

You can do it manually in JH7, just get root and do:

JH7 update removes unlock code - Page 3 - xda-developers

If you have JI6/Froyo/2.2, you'll have to wait until someone else figures out how to extract since it's now encrypted/obfuscated. I don't think flashing back will work either (or so I heard).

Mui, thanks a lot! My Captivate with JH7 is unlocked successfully. And thanks to pingpongboss and everyone else who gave any advice.

Here I listed what I did as a reference for other newbies like me:
1) Download and install "RyanZA's OCLF 2.0" from the Marketplace.
2) Run the app "One Click Lag Fix". Select the option "Root Device 2.1". After finishing, power down your phone.
3) Once your phone is off, hold down both the Volume keys (up+down) while powering on the phone. Release the power button as the phone begins to boot but keep the volume keys depressed.
4) Once at the Android system recovery menu, use the volume keys to select "reinstall packages"
5) Assuming that's successful, your phone will reboot again. Your phone should now be rooted.

After rooted the phone sucessfully
6) Download and install "Android Terminal Emulator" from the Market.
7) In Terminal Emulator, type:

su
busybox grep -E "^[0-9]{8}$" /efs/nv_data.bin
then the unlock code will show up. Write it down for later use.

8) Power down the phone. Insert a SIM card from another carrier and power on the phone. When prompted to input the Network unlock code, input the code you got above. Now it is unlocked successfully. Done.

Just an FYI - I unlocked when the method for finding the 8 digit code in bml3 first came out. I have since flashed my phone a few times. At least to the Froyo release - maybe a 2.1 i9000 release - but now my bml3 file has FFFFFFFF where the unlock code used to be. The phone is locked again, and the original code no longer works. Recently flashed back to JF6 and then upgraded to JH7 via Kies.

One other developer has discovered this, and started some work on sorting it out. Hopefully more details to come.

Yep it works.
I used HexWorkshop for windows to find the code

I did the following...

Code:

... 51531930 is the unlock code! ... the second set of numbers (separated by periods). Pop in a foreign SIM and it'll ask you for an unlock code. Punch this baby in and you're unlocked!

I followed your example but used both /dev/block/bml3 & /eps/nv_data.bin finding similarly placed codes, & same values: SSNV..27503752.73527908.00000000100100101#31015031017031118031041031098099999 hence 73527908 [same value both files]

With an old VoiceStream sim I entered the code after rebooting.. no response. Further dithering caused me the "spend" of my 10 tries, while entering the found code caused no loss of tries[?]

btw-the unlock app script failed to copy the nv_data.bin , hence not having the file to search later in the script. adb shell got me access to the files just fine.

fporter · Oct 26, 2010

Steps in post #45 worked for me using a T-Mobile pre-pay SIM on Captivate w/ JH7. I already had my phone rooted using OCLF.

Wish I'd known in August when I went to Europe! Or, well, back then it wasn't JH7 yet.

Thanks all!
