Hello all
I recently got a great deal for a Vibrant (150$ contract free, looking brand new ).
I live in Europe and I already own a Galaxy S, so I thought "hacking" the Vibrand would be a piece of cake... well it wasn't Finally after reading a ton of stuff here on the forums I managed to beat it using Odin.
After finally getting root the first thing I did was to download Galaxy S unlocker from the Market so I could use it with a local SIM card... and it failed. The app couldn't find any codes? and neither the root or non-root method worked.
The Vibrant recognizes that there's a SIM card, and even asks me for a PIN on boot... then nothing happens. When I try to make a call, "Data network not available" is displayed.
The network here is GSM 900/1800.
I'm currently on the deodexed KB5 2.2 ROM flashed via CWM.
Any help would be greatly appreciated
Hmm...I believe there was another method to unlocking it other than the Galaxy S unlocker program you have. It will require root which you have.
Search around the Vibrant forums, I think it was from at least a few months back.

Yes, I found it but I'm not sure wheter it's a lock issue (it said "no codes found") or I have to flash an European modem or something. I'll try it anyway and report any results.
No luck
All the methods work for 2.1 and I'm on Froyo KB5.
Plus it's not really an unlock code issue..
It's rather... the SIM card doing nothing.
- Is it insearted?
Yes
- Does the phone recognize there's a SIM card?
Yes
- If you have a PIN, does it ask for it on boot?
Yes
- Well what's wrong then?
I can't do anything else with the SIM... not even join a network
Did you per any chance lock your SIM card with a PIN code?
Cause if you did, it is asking for the code that you locked it with. . .
Try another, UNLOCKED SIM card just to be sure that's not the issue.
The phone SHOULD ask you for an unlock code only. A pin code request (unless you are reading the unlock code as a pin code) means the SIM card is locked.
The card was unlocked, I put the PIN on purpose later, just to see if it'd recognize that
Then what is the issue? Without the PIN, it recognizes the SIM and loads up fine but doesn't get on any network?
Yes!
And that way it's just a VERY overpowered iPod touch. Would be nice if I could actually make phone calls from it, but if not - whatever.
I remember anything above 2.1 theres an issue with the SGS unlocker on the market. I had to use a different method, and I don't remember where I received the instructions from, but I did find this for you on youtube. Please do watch the whole video as the person has the same problem, but runs you through the steps to unlocking by using a different method.

gosh... no dice.
The phone never asks me for any unlock code, just stuck on "Searching"
Try a different modem. If not then try a different rom..may be?
Why not just odin back to stock,reroot, and try to unlock it before flashing a rom
Sent from my GT-I9000 using XDA Premium App
Will try that in the evening and report outcome ^^
I wanted to sell my Galaxy s2, the guy wanted it to be factory reset, with the original firmware.
I have downloaded GT-I9100_XME_I9100XWKF1 firmware, it worked. But I had the "sim locked" symbol in the notification bar, so I wanted to unlock it.
I downloaded CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4, and rooted the phone.
Downloaded the Galaxy Unlock app from market place, followed steps 1-3. Phone rebooted.
The unlock didn't work, Instead of a sim locked symbol in the notification bar, I got this stop symbol (like in "no smoking" sign). When I try to go to settings->wireless and mobile network->mobile network, I get "Insert Sim Card to access network services" (sim card is insert correctly, i double checked). When I try to make a call, same message "Mobile Network not Avaliable".
I did some search on the forum, one of the guys said that I should check if the IMEI is matching, I dialed *#06# and got the word: "IMEI", no serial, just that.
I tried to go to Unlock Galaxy app and do a restore efs (step 4), i get the message "You don't have efs save in /sdcard/Galaxy_S_Unlock"
I tried the sim card in a different phone, it works. Tried a different sim in galaxy, it doesn't work.
I tried to do a reset of the device from a backup I had from a month ago, it didn't help, same problem.
What can I do?

Thank you for the reply, I have tried the GSII_Repair, just now, I installed busybox on android device, and followed the steps.
Step 1 was succesful, so was 2.
After trying step 3 i got the message : "You dont have .nv_data.bak and his md5 files, canceled"
I did more research and found out that I have network lock. Punching the code *#7465625# confirmed it.
I tried that tutorial: http://forum.xda-developers.com/showthread.php?t=1369474
to fix it, it didnt work because I didn't have the hex adress 181468 nor 18145C in my nv_data.bin
do not use galaxy s2 unlock, try galaxy S unlock, this one is better but with greater risk but never heard anyone had issue with this. Use this then do the GS repair again.
should this one did not work, i suggest you do odin flash of official roms. Tried flashing the rom 3 times, I was able to fix the same problem with my galaxy tab before doing that. goodluck.
THank you ! *FIXED*
I just used the original Samsung Unlock, and I didn't notice that it had a fix built in. Tried it and it worked !

Hey dude, which "original Samsung Unlock" you used? Can you post the link for download? Have same problem as you, have tried many things but none worked.....
Great congrats...
Hey guys hope you can help me.
I bought the code to unlock the network on my galaxy i9100, currently is locked to telcel mexico.
The thing is that I put in an AT&T sim card and no imput is displayed to enter the unlock code, when I put a T-Mobil sim card a blue lock is displayed saying Network Lock and a button sayin dismiss but no input to capture the code.
So what should I do? I was seaching in several posts and I think that changing the rom to another not from telcel can allows me to capture the unlock code, do you know if that is true? if so, can you tel me, what ROM is compatible to my samsung galaxy I9100 from Mexico ?
Thanks.
SIM Unlock SGS2 Telcel
Hi, I got last week my SGS2 for Telcel and I'm afraid you waste your money with the code, don't worry I also bought an usefulness code.
I did these steps:
DIAL *#SIMLOCK# (7465625) you will have a popup displaying Personalization status, the option NETWORK LOCK [YES] means your mobile is locked for TELCEL, the other options displays OFF.
IF you have NETWORK LOCK [OFF] means your mobile is SIM unlocked.
First you need to root your device, look in the forum how to do that and download busybox.
Well to unlock download from the market the app Galaxy_S Unlock market.android.com/details?id=com.helroz.galaxysunlock (it works with S and SII)
Open the app and follow steps, WARNING there are two steps for number two, I used second one.
Once finished, reboot the mobile and dial one more time *#SIMLOCK# you will have now NETWORK LOCK [OFF]
However I installed a SIM from IUSACELL it doesn't work, what worked for me was downgrade the the version to 2.3.3 reboot with IUSACELL simcard adn voila it is working. After IUSACELL simcard is accepted I upgraded to 2.3.6
You can change the version, root, no matter which change, even restore to Telcel image and the mobile will continue unlocked.
I hope it works for you, if you have any problem just let me know via DM or my twitter @D4N13L0G

What ROM is compatible, I downloaded one from the link above, one from telcel, and works fine the problem is that when I switch the sim card it says that is network locked, so I need another ROM but i dont know what is compatible with telcel, any help?
Thanks
thanks to hugeband here is the guide that he sent to me to downgrade the galaxy s2(telcel), the only proble, that I had, was that i return to android 2.3.6 from telcel, and the Rom is locking the sim card again....
to get the guide please send me a PM or to hugeband and we will send you the URL.
There's something odd, I unlock the galaxy s2 with the method described here and I am pretty sure that it is woking, since my GS2 is using now a T-Mobile sim card, well, the odd thing is when I switch the sim card for an AT&T sim card, the GS2 is still displaying the sim card error message.... I don't have the telcel rom anymore but this message is still happening. Odd thing.
Similar problem
Hi i have a similar problem. my network block is off but I still can't use my iusacell sim. The problem is that i am already in 2.3.3. What should I do?
The problem is that Telcel's modem is a locked one, so even if your device is "technically" unlocked, the modem file will keep popping that annoying lock thing.
1) Dial this from your phone*#7465625#
2) If you have the network lock off, go to next step, otherwise try to follow the second post of this threat until your network lock is off.
3) Flash any rom (or modem file if you wish to keep telcel's crappy apps) from here http://forum.xda-developers.com/showthread.php?t=1075278 After carefully reading the guide posted by Intratech and then try to switch sim cards again.
*As always be very careful before flashing anything and read all of the instructions. No one can take responsibility if you mess something up except for yourself... If you follow the instructions to the letter you should have no problems, as myself and others have done this before.
*If you have any more questions please post them in this threat so more people can learn, I will not respond to PMs.
http://forum.xda-developers.com/show....php?t=1075278 Not working anyother links or forum?? i cant seem to unlock mines, same telcel i tried helroz method but still cudnt work but wen i dial *#7465625# everthing is off
Hi,
the problem is:
I have a galaxy s3 (i9300) which i'm not able to unlock. The *#06# shows the correct IMEI, which is printed on the label behind the battery.
I've tried editing nv_data.bin, but can't seem to find the 00181460 address.
Galaxsim says "unable to load nv data"
The problems started about a month after i upgraded to 4.4.4 (back to n00t rom). One morning the phone just kept saysing 'unfortunately com.android.phone has stopped working'
I tried reflashing it, then tried using cm13.
Everything works fine, except there's now a sim lock on my phone..
running out of ideas, so thought maybe you guys have some fresh ones.
Thanks!
The standard repair-procedure is to flash firmware by Odin.
hello, i have the same problem. i tried lot of rom to solve the problem but it don't do anything. Also flashing firmware by Odin don't work. I'm happy that i'm not alone.
sorry for my bad english.
Hello, have you ever tried to flash the stock firmware with Odin ? For me, it did not solve the problem. If someone has a solution. ..:crying:
The phone is network locked or is the SIM card locked with a pin?

hi, the phone is network locked.
The only method that may work to unlock the phone for free is the regionlockaway app with root and an older modem.
Was the phone ever network unlocked ?
Thanks for your answer .
Yes, the phone was network unlocked when i bought it.
i tried regionlockaway, but it don't work.
I don't know what to do.
Not sure why the phone would relock. You tried installing a stock rom?
I tried this too, but it don't worked.
I tried to change The modem, the CSC, but nothing happens, the phone remains network locked.
Did you check to make sure the phone was network unlocked when you first got it?
Yes, it was unlocked.
no network after custom rom 4.4.4
Hi all!
I also have the same problem after a cutom Rom install, >no Network, Hope you be of help as i expect XDA always do :angel:
No network is not the same as bein network locked.
If the phone can't be unlocked for free, an unlock code must be purchased.

My Gt-i9300 shows my sim as it is LycaMobile but also gives me 'Emergency calls only; so i cant call and etc... is there a way to restore it to full stock firmware ? because i also flashed baseband modem etcetera , and ididnt change to Gsm only ( i read somewhere that be a solution...?
Changing to gsm only will only give the phone data access at edge speeds.
To return to stock, flash a rom from sammobile.com using Odin.
I bought an unlocked phone to change operator when i want and i still have to pay ? Oh misery... :'(

Did you confirm the phone was network unlocked when you first got it? The phone supports your carrier's radio frequencies? SIM card works in another phone?
You can use turbosim for unlock but i dont know what happen to you. Its only suggestion.
You can't network unlock an s3 for free if it has ever been updated to 4.3.

Phone displays "Network Locked SIM Card" Inserted after flashing a stock firmware
I recently uninstalled Magisk, and was able to only boot into download mode after. So, I downloaded a stock firmware for my s9+ 965f and flashed it through odin (using AP,BL, CP, CSC(didnt select HOME CSC). But after rebooting, the phone displays "Invalid SIM. Network Locked SIM Card Inserted".
It asks for PUK code to unlock the phone and the cellular service alone is not working now. My phone is already region unlocked and I have been using it for the past 8 months. Has anybody got this issue and any suggestions on how to solve it?
Previous OS: soldierx rom for 965f v12 on Oreo
What I did,
i) uninstall all modules in magisk,
ii) uninstall magisk,
iii) phone auto-reboot
iv) Now phone stuck in download mode. Cannot boot it
v) downloaded stock firmware G965FXXU2BRGA
vi) flashed through Odin(AP,BL,CP,CSC)
vii) Phone completely formatted and boots up.
"Error:Invalid SIM card inserted. Network Locked SIM card detected "
I am now being asked for PUK code or cellular service wont work
You need to contact your carrier for PUK code, its protective measure against too many wrong PIN attempts on specific SIM. Can't fix that with any flashing.

This is where the problem is. You put any sim card in that phone, you get the same error. The sim card works fine if I put in any other phone. I am not sure but unistalling Magisk has caused "SIM Card Read Error" in my S9+. I even upgraded to Pie from Oreo and flashed 3 different stock firmwares but the sim card error exists.
@topjohnwu
I would appreciate if you can help me on this. Not sure how to fix the issue
Looking up the error message itself points to some sort of network/carrier lock. If I am reading regional lock and carrier lock definitions correctly the two are not the same..
Did you have the phone network unlocked or was it network unlocked when you had root installed? If the device was network unlocked when it was rooted and you flashed back to stock (which removes root) this might explain what is going on...

This is an unlocked phone. I had magisk installed and when trying to uninstall it to upgrade to latest magisk, the device wont boot except download mode. So, I downloaded stock firmware and flashed it. Once I boot up with the new stock firmware, I get this error
There is some sort of lock on the phone, which is why your being asked for the code.
I think you should definetly try was what was suggested above.. trying to contact the carrier and see if they can give you the PUK code. If I recall correctly you get a few tries to enter it correctly before it won't let you anymore (and it might lock the phone up good or damage the sim)
I'm having a similar issue on a Verizon A50. Any progress?

depending on what method was used to unlock it, its likely no longer unlocked. some sellers of unlock codes neglect to mention that part. im betting its locked again
