What worked for all the time was as someone said before...tell them you are going out of country and you need your phone to use while gone.

A bit of trouble

I was directed here to root my sidekick 4g. I rooted my phone using the OneClick program and next to the FFFFFFFFFF0100000000 code all that comes up is "ÿÿÿÿÿÿÿÿÿ.....15" at both occurences!!

not working

***** IMPORTANT ROOT IS REQUIRED BEFORE PROCEEDING *****

***** ALSO PLEASE READ CAREFULLY BEFORE ACTUALLY APPLYING STEPS *****


All right ladies and gentlemen, coders and non coders I have personally found the unlock code NOT THE FREEZE CODE only the unlock code for your Samsung Galaxy S 4G hidden in the same files as previous Vibrant phones.

Please understand this was a hard complex and still needs work procedure.

Of-course this all depends on your dedication and time but hopefully I have simplified it for you.

Steps:

1. Install "010 Hex editor" you can use trial does not have to be registered

2. Go to your SGS 4G and open a terminal emulator (free on the Market) - (Root Required)

The following steps are credit to SS2006 on a different post

*** Dont forget the (su) command *** after the second line
_____

after opening a terminal emulator type the following

cd /dev/block <enter>
su <enter> <at this point your phone will ask for superuser access ALLOW it if you already havent done so>
dd if=/dev/block/bml3 of=/sdcard/bml3.bak <enter>

Go find the file on your SD Card and transfer it to your computer

3. Open 010 Hex Editor

4. In 010 Hex Editor go to the Menus above and select VIEW>LINEFEEDS>SELECT CUSTOM>SET YOUR BYTES TO "32" Nothing Less

5. Locate the bml3.bak file you created and transfered to your computer and open it using the editor

(CREDIT TO FR0Z3N FOR CLARIFYING THE FOLLOWING 2 STEPS)

6. Using your keyboard select CRTL+F to search for a hex string, when the search window pops up select "Hex byte" in the Type field and then search for the following string below:

"FFFFFFFFFF0100000000" ALL TOGETHER, Then Hit the FIND ALL button to the right, some of you will get 2 results and others up to 10 results on your screen below

7. If you look at your Hex editor there are 3 window panes on the selected line (See Image Below)

e.g 4CCC60h <-- Offset
01 01 01 01 < -- Hex Keys
yyyyyyyyy <- ASCII text where your code is

h.t .t p / / i1201.photobucket . com /albums/ bb359/sanfranx415/unlock.jpg

8. Go through each result from the above search and you will see on the 3rd window pane (as shown on pic above) after the hex keys there is an 8 DIGIT CODE (Write this code Down) this is your unlock code NCK for your phone

Sidenote: THIS 8 DIG CODE SHOULD SHOW ON AT-LEAST ONE MORE RESULT CHECK ALL YOUR RESULTS FROM THE SEARCH ABOVE IF YOU HAVE ANY DOUBTS ( SOME OF YOU WILL HAVE YOUR CODE SHOWN AT-LEAST 2 TIMES AND SOME OF YOU WILL HAVE THE CODE SHOW MORE THAN 4 TIMES BUT YOU SHOULD NOT HAVE THAT MANY RESULTS )

**** TO INPUT THE UNLOCK NETWORK CODE DO THE FOLLOWING ****

9. Turn off your phone

10. Insert a foreign SIM card not attached to your current provider (e.g if you have T-mob use an ATT SIM CARD) and turn on your phone

11. You will be prompted to enter a Network Unlock Control Key ( Use the code above that you wrote down and type it in your phone exactly)

12. After entering your NCK please hit Unlock or GO button and you should see a screen that says "network unlock successful" and your phone should go in the main screen after your phone has been unlocked.


THATS IT FOLKS HAVE FUN

PS> If you entered an incorrect code you must of entered the wrong code or wrote it down wrong please read carefully and verify the code matches the results from above in at-least more than one instance

No such file found.

So I had this device unlocked and then it took a swim with me. I repaired and reloaded the phone and went through the steps to extract the code as the original code no longer worked. I tried entering the if= command 3x and it says there is no such file. I browse to the file with File Manager and it reports the file is 0 bytes in size. Any suggestions?

Question for y'all - if I'm going to be traveling out of the US but will have wi-fi access in my hotel & etc., is this necessary? That is, will "Wi-fi calling" work from IP addresses outside the US?

Thanks. :)

Easily extended to Mac and Linux!

Worked perfectly! If you don't have a windows computer (like me!) it's even easier on a linux distro or a Mac. After generating the bml.bak file on your device, simply copy it your desktop (via the USB connection) and open it using any Hex editor of your choice.

    ICS users!

    FYI, I have discovered that on my SGS4G running AOKP / Team Acid ICS, following the procedure in OP (ie searching for FF FF 01 00 00) but instead checking the file /efs/root/afs/settings/nv_data.bin works fine.

    Also, and I haven't bothered to check and see if it's as a result of being on a custom rom, but I'm able to use generic file explorers on Android like Ol File Manager (free from market) to just copy the file, no terminal hackery required. YMMV.

    Thanks OP!

    You can call up tmobile and tell them that you want to unlock your phone. They will ask for an email and the imei number. they will email you the instructions and unlock code. It's free and you dont need root access. for some phones, you may need a sim card from another carrier, but you can use one of your friends' if they are not on tmobile.


    Sent from my SGH-T959V using XDA App

    I just unlocked two of them, its on different lines everytime.

    Folowing are the instructions:

    Open the file in Hex Editor

    1.) Press - Ctrl + F
    A window should open up
    2.) Change the type to "Hex Bytes (h)
    3.) Value: FF FF FF FF FF 01 00 00 00 00
    4.) Click Find All, for me the code

    the code is visible right after this, 8 digit code. For me it was repeared 9-10 times in the file.

    Good luck

    This seems like it doesn't work. If you go to line 157028 you end up at offset 4CAC60h which is nothing but zeros. And if you go to offset 4CCC60h, there's no 01010101 value.
