Hey!
So I used the android SGS unlock app on my Galaxy S GT-I9000T Latin (2.1), and it gave me an unlock code no problem. But when I reboot it with my Rogers (canada) sim card in, it shows me a "network lock" screen with just one "dismiss" button. No option to enter the unlock code.
Anybody know how to get the unlock screen to show on this model?
Thanks for the help, dudes.
Update: tried the *7465625*638*# thing, nothing happens.
I am experiencing the same problem...
I am experiencing the same problem with the same phone on Claro Puerto Rico provider...if you have solved the problem please post how. Thank you!

Any ideas?
Thanks to vnamee and helroz for detailled instructions for the Samsung Vibrant Firmware JI6, Just did this on my GT-I9000T and it works great.
Here are the steps to perform the unlock:
You will need root and busybox and something to edit the root, such as Root Explorer or ADB, I used Super Manager, You will need Java on your PC as well.
1) Copy the EFS folder with Root Explorer or ADB to back up
2) In /efs, delete:
nv_data.bin.md5
.nv_data.bak (you may not have this)
.nv_data.bak.md5 (you may not have this)
nv_data.JPC (you may not have this)
nv_data.JPC.md5 (you may not have this)
.nv2.bak (you may not have this)
.nv2.bak.md5 (you may not have this)
3) Reboot your phone and navigate to /efs to see if nv_data.bin.md5 is created. If it is, you are good to go. If you go there right after the phone boots, it may not have been created yet.
4) Put your phone in USB debug mode and connect via USB to computer.
5) Run step 2.bat (this will extract nv_data.bin to your computer)
6) Run reparation_nv_data.jar (I guess you just enter any 8 digit number in the boxes that will be your unlock code. I had entered '00000000'.
7) Run Step 4.bat (this will upload the files to your phone. Make sure the phone is on and when you run it, make sure to keep pressing 'allow' so the program has root access to push the files to your root).
8) After this is done, you can answer 'n' if there were no errors and it should reboot your phone. Phone should be unlocked.
How can be possible that i can be root in the phone shell and apps, but when i want to su in ADB, i get Permission Denied?
Because of this i can't execute successfully .bat scripts...

That's happening because you probably haven't rooted the phone yet. Thats why you are getting permission denied. Use 4zroot, thats the easiest way to root it.
where is the script
I have the same problem and I tried everything except this script that I don't find.
Please can you tell me where it is ?
still Network lock
I just try the script and still lock. Is this phone locked for ever ? Is that possible ?
Should I try to install a new system on the ROM ?
Network Lock [OFF]
I have
Network Lock [OFF]
but I still can't unlock it.
step 2, step4
After I choose "Wipe cache partition" then I reboot and still "Network Lock" with one choice: Dismiss
I have tried Galaxy S Unlock and SGS Unlock Tool (Pro also), superuser BusyBox, what else...
Why this is so different that what I see on the internet. Is the Telnet (Mexico) Samsung so efficiently locked by the company ?
Serious question: what's next option for me ?
Please help
thanks
Not working, something strange
After trying everything
I have something strange:
If I launch Galaxy S Unlock app
and ask to see Sim Unlock Code
I have a message box
in French(?)
Votre Réponse
Unlock code is: simunloc
Unfreeze code is: unfreeze
if you have FFFFFFFF code,
must use any step 2 for unlock
Something is then locking the phone network over regular code thing....
any idea ?
The GT-I9000T must have a other protection layer somewhere in the software (or hardware ?).
This screen with Network Lock Dismiss seems to be unique in this phone.
Is there a genius around able to find the trick ? Thank you.
Did you really unlock your phone with this ? It doesn't work for me. Telcel probably.
Only way to unlock Telcel's Samsung Android phone is to flash a new fw. The Sim lock is integrated in Telcels FW.
I had to flash my S5830L Galaxy Ace to insert a Movistar SIM.
Sorry - thats the only way.
guidance with flashin my samsung galaxy
Hey unu$ual I am mexican too. I have also tried to unlock to my telcel samsung galaxy s with no success... so far. I have rooted the device, installed the busybox app and Samsung_s unlock app. At the end of the procedure, when i tried with the *#7465625# command it says the Network lock is [off], but when i restart it the annoying message "Network locked, Dismiss" appears.
So, i think i want to follow your advice and I´ll have to flash it with a new fw. Any advice? I'd appreciate if you can share with me the software, firmware version that you used, and if possible the procedure.
Thanks in advance.
Peace up!

I have tried all that in different firmwares (including CyanogenMod) without success. (telcel i9000)
Network Lock
Anyone find a way to network unlock. I'm on Claro Guatemala and want to unlock and upgrade the ROM. I have the code but I get the famous "lock screen"
Which 3rd party firmware works on Telcel/Claro I9000T?
Ok, it's been a few months since the last post here, so I'll give it a try. I am ready to try a 3rd party firmware on my Claro I9000T but I would like to confirm which firmware works with full 3G+ AND gets rid of the network lock screen.
Has anyone been succesful?

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks
Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?
hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"
Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it
did u try restarting the phone... just a wild guess...
I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy
Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .
http://forum.xda-developers.com/showthread.php?t=818556
However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .

Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!
So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

I honestly do not know if you need the SIM card or not to access the market which will allow you to get the "Galaxy S Unlock" app. I have tried the "Galaxy S Unlock" app before but I could never get it working (with stock FW and Stock FW + Root). Im pretty sure that you cannot use that app once you update from Stock FW to Stock FW + JH7 (the original "GPS fix" back in Sept). However, the way I got my unlock code was the following steps:
1) Go back to complete stock FW using the following link:
http://forum.xda-developers.com/showthread.php?t=731989
2) Root the device using the following link:
http://forum.xda-developers.com/showthread.php?t=739304&highlight=click+root
3) Get your unlock code using the following link:
http://forum.xda-developers.com/showthread.php?t=761751
This may be the long method but this is the only way I have ever gotten my unlock code. But then again, once I got my unlock code, I never tried to get it again. The above steps that I took did not require a AT&T sim card at all.
I hope that helps.
Hey! Even i got this phone from United States to India and now even i m in a fix that how do i unlock. please tell me did u manage to unlock the phone?
I have a i897,now baseband unknown，IMEI：unKnown,not detect sim card.
I tried reflash roms (2.1 Eclair,2.2 Froyo) many times follow the way i found in the net, It does not work.
But what Confused me is, Occasionally I turn on or flash a new rom,it sometimes could detect the sim card with "!",and pop up ask for a net unlcok code,if that time I use the Galaxy_S Unlock,It may get work,and the baseband,the imei,the phone,all get work! But once reboot,It does not work again.
Add: Galaxy_S Unlock found the code is FFFFFFFF.
I backed up the EFS after it began to stop work( a little late?),I also backed up the EFS when unlcoked and it began to work,but neither can make it work again.
When It detect the sim card,dialing *#7465625# will show the network status. but most time,i get the error message "com.android.phone has stopped unexpectedly" and I get the error log "traces.txt" but don't know what is wrong.
I don't know what's wrong with it.I googled the internet for two weeks.The hardware error? I opened the phone,and found nothing broken.
Could anyone can tell me what is wrong with my I897?Thanks and sorry for my poor English.
If u have a bakup of NV_DATA.BIN file which u saved when u first unlocked the phone then u can restore the imei on your phone.

slow down and start from beginning.
what were you doing when it first stopped working? were you unlocking the phone?
did it work before unlocking? Galaxy_S Unlock creates a backup. restore backup.
how are you flashing roms? odin one click?
what carrier is your sim? are you sure your sim is good?

My sim card is good, It worked on other phone, I tried two carrier's card (China Unicom and China Mobile,I live in China) ,the same result.
This morning I flash the phone again try to get some picture to show my trouble .Fortunately, I get it.
First I replace the EFS folder use a backup ever worked and flash to I897_UCJF6 through Odin (with pit file).
After flash,the phone reboot,soon I get a FC with red code as 'rst=04...' like this.

After I turn off and turn on twice, to my surprise, It get work,everything get back.

I compared the nv_data.bin,find it was changed after reboot. but I put the original nv_data.bin back ( with the original nv_data.bin.md5 file) ,it does not change and does not work again.
I notice when it works, there is a sim toolbox in my application and disappeared when it doesn't work.

Thanks for the replies and sorry for my poor english again. The Image Verification is so hard to me.
That's weird never faced/seen anything like that before......i would say factory format the phone just intstall the galaxy s unlock by helroz, Back efs on backup folder delete every possible file by the name of NV-DATA.BIN and paste back the orignal NVDATA and reboot.
Or you can try this also http://www.youtube.com/watch?v=JqLK_2I-SBM
I flashed the Rom to 2.3.6,the stock 2.1 is too hard to use. Yesterday, after turned on, It worked again. All I can do is don't reboot it as long as I can....
By the way, my unlock code is FFFFFFFF yet, It worked now!
FFFFFFF is not unlock code. read instructions. if it gives FFFFFF you must do method 2 to unlock you have a rogers captivate.

I mean the Galaxy s unlock detect my unlock code is FFFFFFFF now, but all thing work well and no unlock code is needed ,and if I do method 2, after reboot It won't work,I tried this many times. It is weird.
Hi,
I have a Samsung Captivate that I am trying to unlock. Its out of contract with AT&T and so I called them to get the unlock code. They provided the unlock code. I have a non-AT&T sim card from an overseas trip few years back. I insert this sim card and restart the phone and it asks me to enter the unlock code but am unable to unlock with this code - keep getting "unlock request unsuccessful".
I also got the unlock code for my wife's Captivate from AT&T. Using the same non-AT&T sim card in her phone, when I entered the unlock code provided, I was able to unlock her phone successfully.
Additional info if it helps:
1. My phone is running the official Gingerbread from Samsung whereas my wife's phone is running the original Eclair (with the one OTA update that was initially provided by AT&T).
2. I had rooted both phones when both were running Eclair. However, I lost root access on my phone when upgraded to Gingerbread whereas her phone still has root access. I have not rooted my phone since upgrading to Gingerbread.
3. When I had rooted both phones on Eclair, I had come across a method to inspect the efs/nv_data.bin file manually on this forum to get the unlock code:
Code:
su
busybox grep -E "^[0-9]{8}$" /efs/nv_data.bin
The unlock codes retrieved with above method for both phones are the same as those provided by AT&T recently.
Question is why I am unable to unlock my phone whereas we didnt have any problems unlocking my wife's phone. Would upgrading to the official Gingerbread ROM (non-rooted) from Samsung have anything to do with it?
I had read somewhere that Samsung had encrypted something (bootloader?) with the Gingerbread update for the Captivate that prevented it from being rooted the same way that the Captivate could be rooted with Eclair. Could this be related to why I am unable to unlock my device?
Another thought is whether I would need a different unlock code that works with Gingerbread? I am thinking this is unlikely as my undertanding is that the unlock code is determined by the IMEI number and not the ROM?
Anyway, would appreciate any help/feedback on what I can do to unlock my phone.
Thanks,
-Topper
P.S. Since I tried multiple times to unlock the device unsuccessfully (by entering non-AT&T sim, trying with #7465625*638* code, etc), it shows that I only have one try left to try and unlock the phone.
There are many threads where they describe how to unlock Captivate using manual method i.e. hex editing nv_data.bin file in /efs folder of your phone.
You have to root your phone first if not done so already. Also back up your efs folder on your sdcard and/or your PC. This is a very important step. If you mess up your efs in future(for any reason like while flashing a rom or whatever), you can always restore this folder from your back up. Also back up another copy after you're successful with unlocking that way you can go back to original efs or the unlocked one.
You may use the instructions in this thread to unlock it even though it's for SGS III:

Thanks! I had subscribed to the original thread here but had forgotten all about it. Rooted my phone (still gingerbread) per another thread, unlocked manually as per above thread & confirmed by putting T-Mobile Sim card that both phones work as expected. Glad to see the manual process above still works on sgs iii - so maybe it will work on the exhilarate too.
Hi All,
I've trawled through this forum for quite a while and haven't yet found any answers or similar cases to the issue I'm currently having. Here's a summary of where I am at the moment with my i9305 LTE:
- Got a i9305 locked to EE.
- When EE quoted £20+ and 10-20 days for unlock I started looking at altenatives.
- For one of the alternatives, I flashed to get root and I believe I lost my IMEI. I didn't have an efs backup and was unable to restore via stock flashing.
- Luckily, I had a screenshot of my settings so I re-wrote my IMEI using QPST.
- Decided to go for the legit unlock this time so called EE and paid for the unlock code.
- Pre-root, when I put in my unsupported SIM I would get a prompt for an unlock code, but that doesn't have anymore. While waiting for the EE code, I found that when I inserted the unsupported SIM, I would sometimes be able to connect in very specific locations (e.g. certain places outside the house). Wi-Fi works perfectly.
- When the unlock code came, I attempted to enter it by getting to the prompt using "#7465625*638*#". Although, when I enter the code here, it does not accept it (I have an unlock and an unfreeze code, neither work).
- I have trialed the SIM in various other phones and have had no problems with signal at all, the problems arise when I place the SIM in the i9305.
- I have tried changing the modem, so far no luck...
No idea how to go about fixing this... At the moment I can't use it as a phone.
Here is some more info:
Samsung GT-I9305
Nameless Rom 5.0.2
Baseband: I9305XXBLL3
Android Version: 5.0.2
- Should I keep trying different Modems?
- I've tried to verify whether phone is locked or unlocked, but *#7465625# doesn't work, do you know any other ways that I can diagnose sim lock status?
- Will different ROMs or kernels help?
Thanks for any help!
-- UPDATE --
Have flashed back to stock 4.1.1.
I attempted to sim unlock via the *#197328640# approach, but wasn't able to get it to work...
My current next hope is to try and restore my i9305 to the point where it asks for a code to unlock upon entering a new SIM again... Would really appreciate any help, Thanks!
I've still not been able to fix, but will update when I do in case it helps anyone else :good:
