When I tried it I was getting frustrated because I was getting 700 hits.... but when I scrolled all the way down on the 699 and 700 they both had the code. I guess everyone had a different experience.

Unlocking is relatively easy if you have a rooted phone.
You just need to edit /efs/root/afs/settings/nv_data.bin
Use HexEdit or whatever binary editor you have.
Go to address 0x1468 which looks like: ff 01 00 00 00 00 38 36
change 01 to 00 and you will disable a network lock.
As usual, backing up is for weaklings ;-)
btw, this info is available if you search. I am just repeating what others found.

i was having all kinds of troubles i tried everything and this was honestly the only thing that worked. where there is the 01 00 00 00 00 replace the next 8 2 digit combos with all FF and i unlocked mine doing that....

Will keep this in mind, I'm ordering an used AT&T SIM card to unlock both my sidekick and exhibit II from T-mobile, rooted both phones today, and it's the first time I have something else other than a blackberry
Look forward to keep learning

HELP!!
I have tried multiple times to find the code to unlock my Sidekick 4 G but I keep failing. Can someone find it for me? My bml3.bak can be emailed to you if you can help.

FWIW, this method worked for me. I had followed the other instructions of finding my code in "bml3", but it didn't unlock my phone (even after restarting it). This method worked as advertised.
For those of you who are a little mystified what these instructions mean or are unsure of how to do this safely, here are some more clues (there are plenty of posts/threads explaining these steps in detail in this forum):
1. Root your phone
2. Get "Android Commander" (a PC application that lets you painlessly move files between your phone and your PC) [[if you are an expert, you don't really need this -- or my clues ]]
3. Copy "/efs/root/afs/settings/nv_data.bin" to your PC. Now, for safety, make another copy of it on your PC called "nv_data.bin-ORIG" or whatever.
4. Get a hex editor. The 010 Editor mentioned in various posts is a popular choice.
5. Edit your PC copy of "nv_data.bin" with your hex editor. Make the change mentioned in nmil's post, save, and exit.
6. Back to Android Commander. Copy your modified PC copy of "nv_data.bin" back to the original location on your phone. You will be overlaying the original copy of the file on your phone. This is the most sensitive step, so don't mess it up.
7. Restart your phone with a SIM card that is not from T-Mobile. You should be all clear now (no unlock prompt).
Sorry if I belabored the point above, but there are lots of posts around from people who are not very experienced with such things. ("I followed your procedure exactly, and now my garage door won't open.")

Hello ,
What to do if efs folder is empty?
Please help

restoring a lost IMEI

in the process of flashing the phone no longer show it's IMEI in status or in *#06#.
Carrier blocks the phone, i assume because of this.
seems to me that /efs/root/afs/settings/nv_data.bin is corrupted.
there is no backup file. :-( How do I recreate the file? can I use some other file and patch it with the correct IMEI?

What were you doing prior to this?
Does it ask you for a unlock code?
Details please.

i used odin to flash roms to upgrade to gingerbread.
kc1, kh1, voodoo kernel... it's now at kg6.
the phone was t-mobile unlocked, supposedly.
after i had issues with no calls in or out i noticed the imei reported in software (about phone or *#06#) is 00000000000000.
phone reports registered to the cellular network.
nv_data.bin in /efs/root/afs/settings is only 265kb and in hex editor it's all FF apart from one location with 00000000 values.
on an identical phone i have imei reported correctly. can i use it to recover the other one?

256kb is the right size. It sounds like someone went the route of trying to hex edit the nv_data.bin to unlock and so on.
It's protected by a md5 checksum file.
Try this - back up the nv_data.bin.md5 in the /efs/root/afs/settings folder as well as the nv_data.bin ( just in case ) and DELETE only the nv_data.bin.md5 file. Reboot. Check your IMEI. Post back.

As for locks, it reports all off.

Try this.
Download hex editor.
Open hex editor.
Go look for the nv_data.bin file.
Hit options (the paper looking icon on the botton left of your phone) and click jump to address.
Type 1x1468.
After FF, the next 2 digits probably say 00. Try changing it to 01. And reboot.
If it doesnt work, go back to hex editor and change it back to 00 as thats the network lock.....

You mean address 1468 in hex?
Tried it.
It turned back to 00 after reboot.
Imei still in problem.
Do I need to have the sim in?
I took it out for fear of troubling the network.
Sent from my HTC HD2

I guess not. And no. Having the sim in or not, it doesnt really matter. And you can use the phone perfectly with the imei being straight out 0's. You can call, text, and even use data. Tried it for myself . Unless theres someone else with the same imei. Id say thats a pretty low chance seeing that most people want their own unique imei. Sorry i couldnt help. but hope you can solve your problem!
Sent from my SGH-T959V using XDA Premium App

Unfortunately I can't use the phone with IMEI all in Zeros.
The Carrier blocks me out :-(
I can only switch carrier, but that's a hard option.

Do you think this could help?
Anyone had success?

Tried that, it results with new efs files being created with the default 000 IMEI :-(
I suspect I found the offsets of the IMEI in the file of the SGS4G (it differs from other models) but I can't decrypt/encrypt it so to write there the correct IMEI value matching the sticker.
Parallel to that I could find people able to do that to other samsung models , but no one that can do that to SGS4G

did u get a solution
hi i am using SGH-t959v samsung galxy s 4g. and i unlocked it using nv_data.bin file modification. after i unlocked it says NO service.
did u find any solution for it

unlock galaxy s 4g (vibrant) super problems

hi there experts
i am having a hard time sim unlocking this particular phone. i have no idea what else to do.
the applications by DaGentooBoy do not work. the code comes back NULL
there is no nv_data.bin file anywhere to be found in the phone
i tried the BML5 method, but the string is nowhere to be found in that file.
it seems that the t-mobile galaxy s 4g phone do not have this unlock code incorporated in.
i have tried Galaxy_s Unlock took from the market but it always gives an error saying that i have a problem with busybox. i have tried it on rooted 2.2 froyo the phone came with. i have 2.3.6 gingerbread on right now (stock from samsung loaded with kies and rooted with superoneclick 2.2) but no go same issues. i tried installing different busybox versions. still nothing. i have tried other roms, still nothing. the developers of galaxy_s unlock tool say that there are issues with busybox and droid2.2, but it does not work on 2.3.4, 2.3.6. nothing works.
i have tried and unlocked an att captivate with the galaxy_s unlock tool after root. that phone also had the codes coming up NULL and no nv_data.bin files, but it works with galaxy_s unlock tool.
i am reading here (http://techlab102.com/samsung-galaxy-s-carrier-unlock/) that the t-mobile vibrant phone has a bunch of bloatware that prevents busybox from installing correctly or at all. they said they installed some manager and uninstalled this bloatware, but fails to says which ones. i am looking at a ton of stuff in the phone with the manager, and i have no idea what to uninstall in order for the busybox to install correctly anf for glagy_s unlock tool to work.
if anybody can point me in a direction that would allow me to do this i would really appreciate it. thank you very much.
jmecherul
EDIT: this is the galaxy s 4g from t-mobile (no the vibrant). is it possible that the nv_data.bin files is somewhere else in the phone no in the usual spot?

The nv_data.bin should be found in
/efs/root/afs/settings.
i dont recommend the apps as ive tried them, and all of them nulled my imei. (maybe thats just me).
Sent from my SGH-T959V using XDA Premium App

i found it
wondering why the nv_data.bin is in that folder instead of just /efs on the galaxy s 4g. funny.

If your imei is already null and you have no backup of the efs folder or even the nv_data.bin, im sorry i cant help you, you should ask a true expert.
If you do have a backup of the original unedited nv_data.bin, youre in luck.
Step 1: delete the nv_data.bin file from the original folder.
Step 2: move the backup of the nv_data.bin file you have into the original folder.
Step 3: open up your hex editor of choice, and go to the nv_Data.bin file. Hit options, jump to address ->1468 after the ff, you will see 01 00 00 00. (these numbers represent the locks. 01 is the network lock.)
change the 01 to 00. Save it, and close hex editor.
Step 4: delete the nv.md5 file located in the same folder as the nv_bin file.
Step 5: reboot.
if you dun have the backup, i just spent time writing that for nothing T-T

i see where it is now. i did read that procedure with the nv_data.bin on the website, but seemed complicated and i thought the file is somewhere else. but, follower the procedure and worked like a charm. thanks

hi LIGHT
thanks for the heads up. my imei was fine. i suppose by NULL you mean that it shows NULL instead of the 16 digits in settings/about phone/status. it was never the case with mine. i am a little bit of an idiot because i was trying to do it the easy way using the software instead of dipping my toes into a little bit of linux stuff. the procedure was right there in front on me (there is a big post about it) but mentions the software below the hard way. but, got it working and now shows network unlocked and takes other sims.
it is kind of funny how the att captivate worked with the GALAXY_S UNLOCK software and the S 4G does not. it seem that t-mobile is doing something funky. although, it just struck me that i could have called t-mobile and ask them for an unlock code, but i kind of wanted to do it myself.
thanks anyway. it is much appreciated

By null, i mean 0000000000000000.
But glad you figured it out.

You have to root your device and change nv_data.bin file.
Try this:
1. Copy nv_data.bin file from efs folder to your PC
2. On your PC open nv_data.bin in a hex editor (XVI32 or similar), go to hex address 181468, you should see FF 01 00 00 00
3. change 01 (after FF) to 00 (it's a network lock flag) and save
4. On your tab: delete nv_data.bin and nv_data.bin.md5 from efs folder and put modified one. Then reboot device.
Put you sim card and enjoy

How to fix LG G2 with IMEI issue

Long story short, I bricked my lg g2 d801 after flashing twrp recovery and trying to flash custom rom. The phone would restart randomly. I had no connection and the signal bars crosses out in red. In settings most of my info like baseband, imei etc were missing. I was looking up and many people bricked their phones with no EFS backup to restore the IMEI. This is how I fixed my phone. This should also help people who have zeroed out IMEI after bad flash or whatever reason. But you should at least have IMEI number ready (from your box/ receipt or call t-mobile)
1. Flashed the phone to factory firmware using LG support tool. I used the following guide:
http://androidcure.com/unbrick-lg-g2-stock-firmware/
used the firmware: T-Mobile KitKat D80120A_00.kdz
there's also similar guides in xda, follow whichever you prefer. Goal is to revert the phone back to stock.
After flashing the phone, the phone was woking; however imei was null. In phone settings my IMEI was 0. To fix the null/bad imei follow this guide (Not all the steps are my work; this guide helped me http://forum.xda-developers.com/showthread.php?t=1942417 , also watched some you tube videos):
2. You need the following drivers and software:
LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1
QPST_2.7_378
imei converter: http://www.sendspace.com/file/a3spfh
3. After installing the driver; turn on USB debugging and connect the phone to computer
4. Install QPST, run QPST configuration from from start menu
5. Click on Ports tab. Click Add new port. Your phone should be COM4/5. It will say USB after the port. Select the port and click OK.
6. The port should come up on active phones. Select the phone and and click on "Software Download" from start clients menu
7. Click on Backup tab. Your port should appear. Backup by clicking on start
8. Now go to Program Files/qualcomm/qpst/bin folder
9. Run RF_NV_Manager program
10. Click File read from phone. Your IMEI should appear on number 550; NV_UE_IMEI_I
11. In my case; there was no item 550 as my IMEI was missing. Don't worry.
12. Click on file> Read supported RF NV items
13. Now click on item 550. It should show 9 blank fields.
14. Start IMEI converter. Type in your IMEI in enter IMEI click on convert IMEI
15. There will be 18 digits in groups of 9
18. In RF_NV_Manager program; click on Hex by Write NV button
19. IN the 9 boxes; type in the numbers from IMEI converter starting from left. Type in first group of two numbers in the first field, then go to the next field and type in second 2 digits
20. After you fill in; click on write NV
21. Now click on File> Read from phone. NV item number 550 should appear now.
22. Unplug, Restart your phone and your IMEI number should be there and phone should connect to network.
Above process fixed my phone with full 4G LTE data. Now depending on the how bad your EFS was damaged; you might not get 4G lte data. But at least now; you will be able to send the phone back to LG for repair or return to t-mobile as IMEI number will be in your phone.

You can do this with EFS Professional. It does all the conversion for you and you dont need QPST. Just simply type in IMEI and write to device.

I've tried the this guide and it didn't work for me. I get an error when I try to write NV. The good news is that I don't have an immediate need to change/fix IMEI but I was wondering if it ever gets zeroed out I have a way to restore it. I will give your tool a try.

So the EFS Professional is compatible with phones other than Samsung? Once I've unzipped the file I see a bunch of binaries for Samsung phones, but nothing for LG G2. When I try to run it generates an error the app is for Samsung devices only... Where can I get a compatible binary for LG G2 or EFS professional that works with LG G2?
I've tried Qualcomm NV Tools instead of EFS Professional and I cannot create a backup. When backup is being created it errors out saying the device has been disconnected... Also if I write the IMEI it says it was accepted but it doesn't change.
PS: I should probably start screweing around with these apps since I may introduce the problem. My IMEI is fine.

Imei will only write if zeroed out. You are correct, EFS Professional is for samsung devices but the Qualcomm NV Tools is universal. I am currently in the middle of updating it so more features can be used on other devices.

Long story short, I bricked my lg g2 d801 after flashing twrp recovery and trying to flash custom rom. The phone would restart randomly. I had no connection and the signal bars crosses out in red. In settings most of my info like baseband, imei etc were missing. I was looking up and many people bricked their phones with no EFS backup to restore the IMEI. This is how I fixed my phone. This should also help people who have zeroed out IMEI after bad flash or whatever reason. But you should at least have IMEI number ready (from your box/ receipt or call t-mobile)
1. Flashed the phone to factory firmware using LG support tool. I used the following guide:
http://androidcure.com/unbrick-lg-g2-stock-firmware/
used the firmware: T-Mobile KitKat D80120A_00.kdz
there's also similar guides in xda, follow whichever you prefer. Goal is to revert the phone back to stock.
After flashing the phone, the phone was woking; however imei was null. In phone settings my IMEI was 0. To fix the null/bad imei follow this guide (Not all the steps are my work; this guide helped me http://forum.xda-developers.com/showthread.php?t=1942417 , also watched some you tube videos):
2. You need the following drivers and software:
LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1
QPST_2.7_378
imei converter: http://www.sendspace.com/file/a3spfh
3. After installing the driver; turn on USB debugging and connect the phone to computer
4. Install QPST, run QPST configuration from from start menu
5. Click on Ports tab. Click Add new port. Your phone should be COM4/5. It will say USB after the port. Select the port and click OK.
6. The port should come up on active phones. Select the phone and and click on "Software Download" from start clients menu
7. Click on Backup tab. Your port should appear. Backup by clicking on start
8. Now go to Program Files/qualcomm/qpst/bin folder
9. Run RF_NV_Manager program
10. Click File read from phone. Your IMEI should appear on number 550; NV_UE_IMEI_I
11. In my case; there was no item 550 as my IMEI was missing. Don't worry.
12. Click on file> Read supported RF NV items
13. Now click on item 550. It should show 9 blank fields.
14. Start IMEI converter. Type in your IMEI in enter IMEI click on convert IMEI
15. There will be 18 digits in groups of 9
18. In RF_NV_Manager program; click on Hex by Write NV button
19. IN the 9 boxes; type in the numbers from IMEI converter starting from left. Type in first group of two numbers in the first field, then go to the next field and type in second 2 digits
20. After you fill in; click on write NV
21. Now click on File> Read from phone. NV item number 550 should appear now.
22. Unplug, Restart your phone and your IMEI number should be there and phone should connect to network.
Above process fixed my phone with full 4G LTE data. Now depending on the how bad your EFS was damaged; you might not get 4G lte data. But at least now; you will be able to send the phone back to LG for repair or return to t-mobile as IMEI number will be in your phone.

Hey kingroach, amazing guide, wonderful!
I followed everything step by step. Right now I have some generic IMEI which does not work, I'm trying to write my original one back, but at step 20, when I click "Write NV", the numbers change, the Hex unchecks and the popup comes out. When I close it, Hex goes back to being checked and numbers return to what I made them. and I get this popup:
Here's a video.

You can do this with EFS Professional. It does all the conversion for you and you dont need QPST. Just simply type in IMEI and write to device.

Hi, thank you for your help too in these threads. I tried EFS Pro, everything checks out, it says IMEI written, but when phone is restarted, nothing has changed. Do you know if EFS Pro need some other setting enabled to actually change the IMEI?

Try deleting 550 nv item which contains the imei and save. Restart the phone and add it.

I couldn't - you try with the custom list, under tools I think. You move item 550 from the right column, and it dissappears, but when I read NV phone items, its there. It's untouchable I tell you!:silly:

i tried. but at step 5, my my PC said "No Phone". can you help me ????

I keep getting
Exception Thrown!!
NvManager::getNvItemsFromPhone( const string comport )-
QpstServer::sendSyncImpl - Bad response from phone (DM packet
commands 19-24)
Any ideas? Please tag me in this.

Did you first reflash the stock rom? Someone was getting similar error and flashing stock rom fixed it.

Use EFS Professional to write your Original IMEI ....
