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

Just because it shows the 3 welcome screen doesn't mean it's not unlocked, just branded. If you continue past the welcome screen, are you sure your Orange SIM doesn't work? If so, what method did you use to SIM-unlock it?
Thx a lot for the reply.
Initially i have used Chainfrie's Galaxy S2 sim unlock. but didn't work. Then i have used Helroze's Galaxy_S unlock. After that i pressd *#7465625# it says
Network lock OFF
Network Subset lock OFF
SP Lock OFF
By this way i believe its unlocked. But dont know its really unlocked.
Cheers
Tony
Branded means network branding and add on .
Your is 3 branded
Locked means locked to a network unlocked and it will work on any network .

Not recognize sim first question has to be does it reconize any other sim .Second question have you entered the network settings for orange ???

Mr jje,
thx a lot for your kind reply.Thx.
I only tried orange sim but no help.

Yes it does show the original IMEI no.

By the info youve given already your phone should be unlocked. Will it not make or receive calls or is it just the web that aint working? Does the sim card work in another phone?

Kindly let me know anything else u like me to look for.

Sorry to jump on this thred but noticed the OP had the same kernel, build and baseband numbers as my newly bought S2.
Ive been looking about for the right files to download to root mine but have been puzzled by the right ones to get.
Which are the corect kernel and firmware files I need?
Currently on Three network also looking to unlock and debrand.
Hope you can help

Only two possible answers left .
One you have not entered your networks settings or they are wrong .
If you have then phone is not unlocked .
Simple test .
Phone works with original sim = software OK .
Other sim works in another phone = sim ok
Phone works on another network sim after network setting have been entered if not then its not unlocked phone .

thx for all your support. its working now
Hello
i have rooted my phone because i need to use a different sim. Because i was with 3 it wont let me to use a different sim even after rooting and unlocking it.
The only way if u want to use a different sim is to flash a unbranded official uk firmware on it.Because even if u unlocked the phone after rooting all the bloat ware and the fiemware from 3 wont let u use any other sim (i mean in my case.) but make sure u have already backed up the current firmware before flashing a new firmware.
Please use method only if u bold enough to do it. because if u done anything wrong it may void the warranty.Please do all this in your own risk, to overcome this use a jig u can buy from ebay. or goole it or there is lots of information about this in you tube to reset the flash counter
I will explain what i did to my phone
Step1, Rooted my phone using the method described in android authority and firmware xwlp7 which is described on the above site. here is the link for it please copy and paste on your browser then u will see the method how to do it.
http://www.google.co.uk/url?sa=t&rc...xMSnBw&usg=AFQjCNEAJtIUKzYLRTUMggMwJWe2V-SseA
Step 2,Once u have rooted Get the sim unlock apps from Google play, in my case the Chain fires one didn't work, use this app only once, if u use it more than once u r phone may get locked. Then i have tried Helroz's Galaxy_S Unlock and it did worked.You can check this by typing *#7465625# in u r dial pad once the app run and if u r phone is unlocked it will say sim lock 'OFF'.
But at this stage my phone wasn't working with my other orange sim . The reason was the phone was still on 3 uk firmware that's why the phone wont let me to use any other sim. So i need to find a unbranded original firm ware close to XWLP7 which was my original firmware because i don't really want to try any other firm ware.
So i have found that carphone warehouse uk was using XWLP7 firmware in their sgs2 which is same as mine. Because phones from carphone ware house can use any sim i thought this may work with any sim on my phone as well, You can get this from SAMWARE site where u can find all the firmwares for sgs2, new and old. This site is free and only need a registration. Down load it and extract it in to a folder(tar file). Once you are in the site look for the carphone ware house uk's firmware. I hope you are in Ice cream sandwich 4.0.3
Step 3, Before flashing this do a back up of your current firmware just in case if anything goes wrong , u can flash back. U can do that in recovery mode, (Turn your phone off, turn it back on again by pressing volup+home+power) U have options there to back up, once you done the back up of original firmware in the reoverymode
Step 4, Do a factory wipe/ reset
Step 5, Do a cache wipe as well on the recovery mode this will help u to do a fresh start.
Step 6, Tun the phone off again and turn it on back on down load mode( vol down+home+power button)
Step 7, Start odin which you have used to root the phone in step 1 then connect the phone using the usb cable and odin will recognise your phone (yellow colour on the left hand corner of the odin page) Once this is seen on the pda choose the firmware you have downloaded ( carphone ware house oen from SAMWARE) And make sure only reboot and F.reset time and pda are checked,make sure nothig else checked in the odin. Then let it run, this will take few mins and the phone will reboot.
Hope fully this time u don't see any 3 welcome screen, turn it off and try using the 3 sim first, it should work then try any other sim, in my case that was orange it did worked fine including mobile data so you don't have to change the APN settings for each network provider.
Thanks for the xda develpers, android authority and samware for all their hard work in providing lots of information.
Any doubt let me know. Please do not do anything unless you are really comfortable with
Thx
Go to any of the supermarkets and buy a PAYG sim from another network,{around £1.00}, youi don't have to register the sim to see if your phone is unlocked.
{EDIT} I see you said your coming from a iphone.... So that means its a cut down sim {micro-sim} card.
Parhaps it is not seated in the correct position.
Just a thought..
My phone is doing the exact same thing, can anybody help?
Originally on three UK. Got unlocked in a shop. Orange sim card worked fine. Restored to factory defaults to erase phone. Orange sim card no longer works, but phone is showing as unlocked. Every other network sim card works fine.
Its bugging me, took it back to the shop where i got it unlocked and the man said he had never seen anything like it.
Any help would be great. Thanks
Hi
I have a sgs2. It is originally a bell cellphone/simcard. I now have a telus simcard. The phone now asks for a sim unlock code, when the telus sim card is inside. I have just installed wanamlite 13.0 rom. The phone is rooted, and galaxy s unlock app doesnt seem to work.
A couple of questions. In order to unlock the sim, should I put in the bell simcard, then run the unlocking apps, then get code, write it down. Shut down phone, then install the telus sim card, restart and put in the code from bell sim card?
Im a little fuzzy on the whole process.
The weird thing is that on android 4.0.3 galaxy s unlock will seem to work, and unlock the phone. And it wont re lock after a hard restart. It only seems to stay sim locked under 4.0.4 android.
If anyone could offer some help that would be great. I have also looked into editing nv file with hex editor but I cant seem to find the strings..
Just look for an app called "galaxy sim unlock" and install it and then run it ... u know what to do

hi guys first time here, i have galaxy s2 i9100 says claro when booting, not sure which country, it has spanish and portugues in the languages ., when i do the test for network lock, all four values say off, when i put my simple mobile Sim card , i swap the screen after starting it says network locked, and a figure of padlock, and a button of dismiss, nothing else no place or option to put unlock code, i press dismiss, and back to use all functions of the phone , but no phone service or network, i realized when i put the simple mobile card it addS gsm on the network options and it gives me t mobile and at&t as options when click any of them it fails to register to any, i gave it to my expert friend , he told me it is hardware locked for too many attempt to unlock it, and he will do software unlock , after three days he told me no way it is permanently locked no way to do it at all?? the phone runs android 2.3.4 model gt-i9100, baseband version i9100uhkg4, kernel version [email protected] #2, BUILD NUMBER GINGERBREAD.UHKG7, MY FRIEND TOLD ME IT CAN ONLY WORK ON ORANGE CARRIER WHICH WE HAVE NONE IN US, I EVEN OBTAINED UNLOCK CODE FOR IT BUT NO PLACE OR OPTION TO PUT THAT CODE, PLEASE HELP THANK YOU
You flashed a branded ROM, Claro is a mexican mobile network.
Why don't you go ahead and flash an unbranded ROM?
either way, you're gonna have to deal with the sim lock.
if you have a code, just insert a diffrent carrier on you device and the code screen will pop up when android starts.
here's a few threads that could help you with that matter:

Hello, I'm wondering if there is a guide or any info at all about rooting the KDDI's SGS3 LTE. I saw a bunch of thread for the NTT DoCoMo version but none about the KDDI version. No idea if they use the same hardware or not.
Root success by flashing CWM recovery and sgs3_rooting_supersu_v3.zip. Those tools are specified for Galaxy S3 NTT Docomo (SC-06D) but they also worked for Galaxy S3 Progre from AU KDDI (SCL21).
Just wondering how to unlock this SCL21, if anybody knows, please share.

Hi,
First step is flash the CWM recovery via Odin. You can download CWM recovery from here:
https://docs.google.com/folder/d/0B...ZhbUE/edit?docId=0B98X7HyfoaGaNzNvR052dUp0Wmc
Choose this file: SC06D-JB-KBC-CWM-V6.0.1.2_r10-recovery-odin.tar.md5
Flash that file in Odin, choose the PDA in Odin.
I assume you already know how to flash via Odin, if you dont know just ask me again or try to browse other thread.
Step two is run the CWM recovery. Also, I assume you already know to get into recovery mode. Make backup first in recovery mode, you need to insert external SD card and save the backup in the card.
Step three, download this file sgs3_rooting_supersu_v3.zip from here:
https://docs.google.com/folder/d/0B...ZhbUE/edit?docId=0B98X7HyfoaGaR21wdXZweDdYSXM and save it to the external SD card that you used before.
Step four, run the recovery mode again and choose install from SD card, then choose external sd card and choose the file you donwloaded (sgs3_rooting_supersu_v3.zip). After completing all, reboot your phone and you will see the Super User app. Make sure you download root checker in Play store so you can check whether the phone are rooted or not.
Note: If you run the recovery, the screen will reverse. Dont worry, it works eventhough the screen reverses.
Thats all. I am looking the way to unlock this phone, *#197328640# doesnt work. If you have a clue, please let me know.

Updated:
I found a new thing regarding this phone. This phone doesn't support non LTE sim card, even you have micro sim (3G) card from AU KDDI. I am trying to find other LTE sim card from other carrier in order to check whether this phone works on that sim or not.
May be somebody can explain why this phone doesn't support non LTE sim. In case of Galaxy s3 LTE from NTT Docomo, it works when I used 3G sim (FOMA). I cut the 3G sim to fit the micro slot.

well, my purpose is/was to unlock this phone so I followed the samsung galaxy s3/note unlock method from here: http://forum.xda-developers.com/showthread.php?t=2014982
(I have/had this S3 Progre SCL21, the same phone in this thread)
I can access all the menu and procedure from that thread below, despite this phone being stock Android 4.04!
----------------
"Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone..."
---------------
I put 3G/2G sim card and the phone shows no service. I even put CDMA network sim, no luck. I don't know if this phone is unlocked. I'm wondering if this phone works only with LTE/4g sim. Right now, there's no 4G/LTE in my region
I assume the phone must support all other bands, if properly unlocked.
Now, I'm wandering through the threads and googling.
So far, I'm looking for Jelly Bean 4.1.1 for this phone, which doesn't seem to be available anywhere, even on samfirmware, only stock firmware
Root/flash CWM recovery and try some other unlock method from out there, (after making a backup Stock ROM and sensitive IMEI/NV data of course)
Please keep everyone updated and keep the spirit alive

Actually this phone, SCL21 can be used with LTE sim card only. I already tried to use non LTE sim card from KDDI AU with no luck.
What I am thinking is actually this phone maybe unlock-able by using the procedure as you mentioned (NW Lock NV Data INITIALLIZ). Since the phone can only be used with LTE sim card, we need to try LTE sim card from other carrier in order to test.
The problem is I dont have other carrier LTE sim card right now, if you have you can try it.
Update: Also I am wondering how to make this phone works with not only LTE/4G but also with 3G/CDMA. I changed the band to automatic, but there is no luck. I think this phone is locked to be used only with LTE/4G sim card. So, if somebody knows how to deal with this matter (make the phone not only accepts LTE/4G sim card, but also 3G/CDMA sim card) please share with us here.

Hi everyone ^_^
I just got the SCL21 about two weeks ago. I think it's really strange that even on the Japanese forums, there is very little info on rooting this model. From everything I've found, some Japanese sites also both say it's OKAY to root using the Docomo SC-06D recovery and Superuser zip while others say that it's NOT safe to use that same method and it will result in a bricked phone. Really odd, conflicting messages I think.
What is even more strange is the apparent issue with the screen "reversing"? One of the Japanese sites literally said the screen becomes "upside down" after flashing the SC-06D recovery.
Brong, since you got the root to work successfully , could you please elaborate on the "reversing" of the screen? Is the image upside down and only during the recovery mode? Also, do you know if the root caused you to lose the "osaifu Keitai" touch feature?
Thanks a lot to Brong and everyone else helping out with this model phone!!

Status of SIM access
Hi,
I tested both a 3G micro SIM and a 4G LTE nano SIM from Softbank in this phone and neither card is recognized. The phone acts as though no SIM is inserted at all. (Complete with the "no smoking" symbol (circle with diagonal line through it) instead of a signal meter. I have confirmed that this phone is indeed sold already SIM unlocked from the factory as the MSL is 000000 just like the Verizon Galaxy S III which is also sold without a SIM lock. Additionally, KDDI lists the SCL21 and all other LTE phones they are selling since the debut last winter as being SIM unlocked devices.
According to some Japanese forums, they are suspecting that this phone has some type of hardware lock (hard locked?)... I contacted the only known person who was successful at using a 3rd party SIM on the Vietnamese Viettel GSM network as in a YouTube video. He wouldn't give me any details except that he must have the phone physically in his shop to modify it and it can't be done remotely. This individual also has screenshots showing the stock ROM version running in Vietnamese which makes me believe that he flashed something to the stock ROM to gain SIM detection of 3rd party cards.. Anyone have any ideas about such a hardware locking mechanism?

Actually this phone, SCL21 can be used with LTE sim card only. I already tried to use non LTE sim card from KDDI AU with no luck.
What I am thinking is actually this phone maybe unlock-able by using the procedure as you mentioned (NW Lock NV Data INITIALLIZ). Since the phone can only be used with LTE sim card, we need to try LTE sim card from other carrier in order to test.
The problem is I dont have other carrier LTE sim card right now, if you have you can try it.
Update: Also I am wondering how to make this phone works with not only LTE/4G but also with 3G/CDMA. I changed the band to automatic, but there is no luck. I think this phone is locked to be used only with LTE/4G sim card. So, if somebody knows how to deal with this matter (make the phone not only accepts LTE/4G sim card, but also 3G/CDMA sim card) please share with us here.

my phone need to unlock, please help
He's referring to the service mode. In that case, here are the steps to perform an unlock using the service mode (tested to work ONLY on the docomo models SC-06D and SC-03E; NO GUARANTEE IT WILL WORK ON THE SCL21):
1. Enter service mode by dialing the code in the dialer.
2. Press "UMTS".
3. Press "Debug Screen".
4. Press "Phone Control".
5. Press "Network Lock".
6. Press "Perso SHA256 Off".
7. Menu->Back (if the menu button turns up nothing, then just push "back") then wait 30 seconds.
8. Press "NW Lock NV Data Initallliz" then wait around one minute.
9. Reboot the phone and it SHOULD be unlocked. Works great on the SC-06D and SC-03E, no guarantees with the SCL21. And with the SC-03E newer basebands either hid it away or blocked it out so an older one needs to be flashed in before it will show up for unlocking.
Anyone looking to get one should only do so when they've got a trip to Vietnam in their future (to go get it done in a shop there; they still seem to be the only country with shops doing it) or be using au in Japan.
s3 scl21
that`s the first instruction i found when i was browsing the net and tried it but unfortunately it didnt work...... there are still settings in the service menu and all you have to do is click everything that has something to do with the wcdma to gsm..gsm to wcdma or g to wcdma something like that. There`s also a setting that tells somethin like resetting cant remember the exact word and you have to wait for 90 or 60 secs.and restart the phone .and then go back to changing gsm to wcdma .,there`s a setting also that you have to change the frequency .cant remember the step by step guide but because of my eagerness to use the phone i clicked everthing in the service menu and searched every command listed in there.(dont worry it will not brick your phone).After doing all that... this is what happened .. i thought i failed again because the no smoking sign was still there ...so what i did was i clicked the settings and i was so surprised that the menu for mobile network comes out meaning to say that i was able to unlock the settings on the network ..im telling you guys this is what vietnamese unlockers have been doing to unlock this phone that is why they need the phone physically....thats all thanks
And it never prompted for a SIM unlock PIN again? Somebody really needs to go through this carefully and document it; an SCL21 is only 24-25k yen in Japan; I've heard of people paying more to fix broken screens on their international/American S3s.
scl21
as far as i know this particular phone model (s3 scl21) from AU KDDI is not sim locked . The first time i inserted the 3g simcard, it didnt ask for a pin code or anything ...what i could see was the no smoking sign and the simcard icon is there in the apps menu.
it's diffcult to unlock... i can't use in my country... please help

can you list out the step you taken ? i have 2 phones.
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.
