Samsung Galaxy S3 Unlock Issues - Galaxy S III Q&A, Help & Troubleshooting

Hey guys,
I've been trying to unlock my phone for a few days now. Long story short, I moved from Canada to Japan and now I want to unlock my S3 to use a Japanese SIM.
I bought an unlock code from eBay. I was previous running cyanogenmod but then I was told that rooting will cause issues, so I unrooted my phone after an unsuccessful SIM unlock attempt. (wiped the phone, installed stock TW)
Even after unrooting I still had issues, and was given directions for the Service mode. That did not work either. I have tried many different methods and troubleshooting tips and nothing seems to have worked.
Here are some screenshots of the debug mode, my phone details, and a simple root checker app I installed.

Thanks for reading, and I really hope someone can help ;_;

My first thoughts are that since its from ebay it might not be a real unlock code.

I have had a lot of difficulty unlocking my GS3, as well. I actually got the codes from ATT, my carrier. I've tried 4 times, each unsuccessful. It says that after 5 failed attempts, the phone is forever locked to ATT, so I'm afraid to try that last 5th time. I was wondering if you could root, and then unlock more reliably. Is that possible?

Root makes no difference, you probably don't have an i9300 if you are on ATT.

[I9100G] Network lock

Hello,
I received a Galaxy SII I9100G as a present last april in Morocco (I'm in France right now). They told me it was an "unlocked" phone (not bought from any operator).
The phone worked wonders with my SIM card (SFR, a french operator) from april until 2 days ago. It seems like it locked itself all of a sudden and asks me a code to unblock the network. That same SIM card worked well the same morning.
Anyone to explain what happened? I'm confused since I don't understand how it can lock itself without having to change the SIM card/flash/anything...
I called SFR and Samsung France to have the code, each one tells me to call the other.
I rooted my phone and used Galaxy S Unlock, it tells me that the phone is unlocked but after the reboot nothing happens. Tried also Galaxy S2 SIM Unlock, but it doesn't find the code.
I'm quite desperate right now since I'm waiting for some important calls this week and I tried everything, every tutorial but nothing seems to work.
I really don't know what to do to unblock it, I asked for help on many forums, spent yesterday looking for solutions but still nothing.
Please tell me there's a solution to this problem?
Thanks in advance for any help~
Samsung Galaxy SII I9100G
Version: 4.0.3 - I9100GXXLPN
PS: Actually, it does seem to work with a Meditel (moroccan operator) SIM card... Which I don't understand since it was supposed to be unlocked, hence why it worked with my SFT SIM card since april...
Hey i think some persons before you has coneckt it with a Samsung account and locked it now over the samsung dive webside. You can try to flash a new Firmeware to fix it
First, thanks for trying to help me.
I already flashed it with a new firmware (2.3.6 >> 4.0.3, always using official samsung), but still didn't work.
Unless should I go back to a previous firmware?
Any other idea please?

[Q] Factory Unlocked S3 from China Flashed w/Official JB ROM GlobeTelecoms Ph

Hi there! I really hope someone could help me
with my problem. Well first of, I'm an entire noob with
Androids as I have been a Nokia loyalist
(sucks to be me). I have a factory unlocked S3 GT-i9300
bought from China and was sent to me
here in the Philippines. I have tried
upgrading it to JB 4.1.1 via OTA and Kies
but I've had encountered roadblocks for
the longest time. That's when a friend of mine suggested to use Odin but the
mofo didn't tell me that there were
other stuff that I need to consider (all
the Phone, PDA and CSC stuff posted in
the first post of this thread). So I
downloaded from www.samfirmware.com an official JB 4.1.1 ROM for Globe Telecoms
Philippines since that's the network that
I'm using and flashed it on my S3 via
Odin. Everything went well except for
the part where I'm being asked for a
network unlock code! WAAAAH! My phone is now locked and I don't
even where it's locked to. Is there a way for me to unlock it again
without having to pay those unlock
code generators? PLEASE HELP!!! TIA!
Here is your answer.-> http://forum.xda-developers.com/showthread.php?t=1839200

[Q] Need my stock rom

Hi guys. I got my Samsung Galaxy SII on a T-Mobile contract when it first came out. Unfortunately I got into a bit of a dispute with them and left, and am therefore unable to get my unlock code.
So I rooted my phone and unlocked it and the phone worked fine for a few months. Then all of a sudden I lost my signal EVERYWHERE.
So I tried messing around installing a few roms trying to get my phone's signal back. And may have possibly corrupted my EFS also.
I know (using various guides) how to get my EFS and everything back. However I have no idea which rom to choose.
My phone came from T-Mobile, but I am now on a Three contract. So which carrier do I select when getting the stock rom?
Also CSC? Modem? There are several variants of the stock rom it seems and I have no idea which one to pick!
Sorry if I have missed something, this is my first post. I scoured the website for a good 20mins and couldn't find anything that would help with my particular problem.
Info:
Current Network: 3
Country: UK
Phone: Galaxy S2 I9100
Thanks in advance.

[Q] At&t S4 simunlock help

Hi all
I am newbie to the android world, i was gifted an at&t. S4 i337 model for new year. It was purchased as an unlocked device so it can work in india, but it wasnt,when i load my indian sim ,s4 always prompts with simunlock code.
I read lot of the xda thread to overcome this , intially s4 was in 4.2.2 MF3 build, i was able to root the device but i wasnt able to unlock for international band. So i updated to 4.3 using the thread "http://forum.xda-developers.com/showthread.php?t=2573080" since most of the reviews had positive feedback for unlocking. My software version got updated to 4.3 mk2 build But to my notice after this s4 loads with custom unlocked padlock symbol and rooting dosent work, it always fails when i run the supersu app in disabling knox step.
I followed every step as it said in the thread ,but failed every single time, the thread says it will work only with stock rom, since it boots with custom is this the reason for failure. How can i recover from this. Ur help will be appreciated, i have my s4 unused for past 1 month because of this.
Thanks

[Q] Galaxy i9300 || Unable to Network/SIM Unlock

I have seen a number of questions that are simular to this, but I have not been abe to find one that is like mine, therefore I am posting this.
I have a Galaxy S3 International version that was bought from Digicel Jamaica. It is completely paid for, I called Digicel to ask the for a unlock code. they informed me that they do not do that and I would have to go and get it professionally unlocked. the reason I want it unlocked is that I not longer live in Jamaica, but now live in the US and would like to use the phone for the next couple of months until I can get a phone on contract.
I have tried everything I have seen on this site, including getting a unlock key. nothing works.
I upgraded the phone 4.3 sometime ago and have also rooted it in the pass.
Whenever I try the *#197328640# , after [6] Network Lock I get no menu options see .
PLEASE HELP ME :crying: :crying: :crying: :crying:
I have also tried using RegionLock Away and Galaxsim Unlock, both tell me my phone is unlocked, but I still can't use another sim in the phone.
PS. I am using a T-Mobile Sim from straight talk
You can't region unlock on 4.3 at all, sim lock is possible but only if you buy a valid code -there is no other way and your posts are identical to hundreds of others.

I have a valid code, but the SIM unlock doesn't work with the code. I have tried everything I have seen online, downgraded to 4.1.1, replaced the stock 4.1.2 that came with the phone.... nothing works
