SIM Unlock, blocked??? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

has anyone tried to sim unlock their phone AFTER the update to 4.3???
I'm asking because I have a BELL i337m, upgraded to 4.3 and decided to unlock my phone after.
I tried 3 different sites to unlock my phone, they all gave me the same code and nothing happens
I tried downgrading to 4.2.2 but this wasn't very successful, its stuck in the boot animation screen
any ideas?

I know it's not helping, but I received my Bell phone yesterday and it was shipped with baseband I337MVLUAMG1. I tried the "free sim unlock method" found on this forum, but it doesn't work. I cannot access service mode (*#0011#, Menu button, Back, Menu button, KEY INPUT, 1, OK).
Still searching for a stock rom that will have the service mode enabled...

Dont waste your time looking for a free unlocking service..Pay 29.99 USD and have it umlocked from cellunlocker..you will be happier in the long run as i am..thank me for not wasting time unlocking for free..

I am having pretty much the same problems on my Telus/Koodo i337m. I recently updated to the most recent firmware (4.3) on the advise of cellunlocker because the code I was given was not working. None of the codes work and I can't even access the screens to do it manually. I have recently rooted it, props to Chainfire, but have no luck with most of the service screens. I'm still working with Cellunlocker to resolve the issue. I had access to all the service screens/menus on MDJ but not MG1 or MK6. Wondering if maybe the update missed some files or if the update locked some features. not sure if this is helpful but I'm happy to share whatever information I have to help others with the same problems.

Same here,
Bell with MK6. 3 sites provided same unlock codes. Nothing works, service menus different, etc.
Can't downgrade to 4.2.2 since image found crashed (bricks the phone). Image I found was at Sam Mobile
Apparently BELL will unlock it for 50$ but require original sales receipt, which I don't have (purchased phone on ebay)

Just paid BELL $57 to unlock, and their code is the same as all the sites... NOT WORKING !!!
I wanted them to give me the 1st 2 digits and last 2 digits so I can refuse before payment. But they insisted on pay first - code after - code by email. Luckly I had an employee of Bell at Bell Boutique confirm code not working.
I'm now on hold (1hr) to try see if they have another code?

I think you're right... I ended up buying a code from unlocksamsungonline.com for 29.71$ CAD with a coupon. Received the codes in 55 minutes. Hope it works...

My provider Bell Canada, gave me the same codes as all these sites, and they don't work on 4.3. Looks like Samsung has a major BUG in 4.3 in regards to unlock. Bell says call Samsung ! Go figure!
Problem is that will take a while to fix, aka get it out to consumers....
Chatted with Samsung, they say call BELL !
WoW !!!

Are you sure your phone is locked to bell?
Did you try putting different simcard other then Bell? Did your phone ask for unlock code when you put the other carrier's sim?

this still doesn't work.
Paid and tried from 3 different sites, they all gave me the same exact code
I think that the update has locked the bootloader and anything else.
I was reading somewhere that Samsung may be blocking the sim unlock and forcing people to pay roaming fees
Well all I can say is that this has been a huge step backwards for Samsung (from my point of view) locking/blocking features, really is a major turn off for me.
I think its time to look at other options until someone from XDA figures this one out.

100% locked to Bell
I have the original sim from Bell and is working fine
Put a Fido sim and asks for the unlock code, when I enter it, it says unsuccessful
everything is correct, IMEI has been verified many times and the codes also
Samsung is blocking something here with the latest 4.3 MK6 update

please let me know
BTW, I just got off the phone with Samsung, they say that I have to take this issue up with my service provider.
they are not able to help me and answer why my unlock code isn't working.
he did admit however, that there have been multiple calls about the 4.3 upgrade and that Samsung is going to release an update very shortly
let's just hope that this will rectify the issues that we have been having

I restored my stock rom (Bell I337MVLUAMG1) and was able to unlock successfully my phone. I used a Telus SIM and was able to receive a phone call. BTW, I never updated my phone to the stock 4.3 update.
So it seems that you must be stock for unlock codes to work. For the record, I was using KANGAKAT KOT49H 6.0 when the code was not working...

I unlocked mine on 4.2.2 AMG1 flawlessly.I never updated to 4.3 and looking at the threads regarding KNOX and locked boot loader, probably I never will.
I am wondering if you can flash the MG1 radio from 4.2.2 and try unlocking the phone.If successful install the radio from 4.3 again.
I am not sure weather we are able to flash old radio on 4.3 though.

Vibrant unlock through T-Mobile

I am a T-Mobile customer and I am using a Samsung Vibrant.
Before I contact T-Mobile customer service for an unlock code for the Vibrant I wanted to verify some stuff.
The Vibrant was on stock 2.1 then it was updated to stock 2.2 (KA6) via Kies Mini, at some point it was rooted and a voodoo injected stock kernel was flashed using Odin, after that I flashed back to stock JFD using Odin and updated to stock 2.2 (KA6) via kies mini, and now I am on stock 2.2, no root, no lagfix, nothing...
If I get the unlock code from T-Mobile and I manage to unlock the device, what would happen if I flash back to stock JFD for whatever reason or flash some custom ROM ?!
Would the unlock remain intact? If no would I be able to use the same unlock code to unlock it again?
Thank you.
Sent from my SGH-T959
The unlock should remain.
My unlock has remained through flashing several ROMs and using Odin to go back to stock.
Thanks guys. I will call t-mobile today and request the unlock code.

I would go for this method.
For some reason when I asked for the unlock code when I still had my nexus they refused to give it to me. Probably didn't know what in the bloody hell I was talking about.
hate that about customer service reps.
If you had the phone for more thn 3 months they will give you the code without any issues...
Just go into the Market and search for the SGS Unlock App. It gets your unlock code automatically for you. With the GSM Galaxy S devices the unlock codes were loaded onto the devices, and somebody created an app to exploit it so there ya go.
Sent from my Vibrant running GingerCloneR2
There are multiple threads right now about unlocking. You can do it yourself and there are several methods, just search.
To be honest I read several times that the market application only worked for those who used it on JFD, once upgraded to JI6 it would not work. Right now I am on KA6.
I am a T-Mobile customer and have been for a while and in the past I requested the unlock code for other phones at least 3-4 times and always got it within a day or two... so I see no reason why I would fiddle with any other method if I can get it from the source...
What are you waiting for then?
Yesterday I placed a call to T-Mobile and requested an unlock code. Today within 20 hrs. from the request I received an email with the unlock code.
I requested codes before for other phones and I gotta say this was the fastest response by far for me.
Yeah its an easy process to just get it from tmobile.. did it a couple times with no problems. Just used the bs "im going abroad blah blah blah" story

I too experienced problems unlocking my I337M device (not AT&T, it's the Canadian version, hence the "M" in device model). After trying the keypad menu method and failing, I tried sending my IMEI number into a website to generate a key, but apparently the Samsung servers were experiencing a global delay and they refunded me after two days. (This delay was confirmed from multiple sources.) I then tried a tethered method using an application offered by an unlocking website. It cost $15 (compare at $35 for the IMEI method) and it worked instantly! This was after two days' worth of trying other methods. I won't give you the exact link, but if you google "fastgsm", it should come up. Make sure it's the tethered method. Good luck.
thanx!

The FASTGSM website says:- Warning
Check your phone’s software version by going to Settings > About device. If Baseband version ends with MI1 or later (e.g. MJ1), your phone is not supported for USB unlocking. Use a different unlock method or downgrade your phone’s firmware.
And iam on mf3. So i think it should work!( f comes before i)
I used the FastGSM tethered method, and it worked on my MF3 stock rooted rom. Granted, I do not have MF3 bootloaders, but it otherwise seemed to work. The instructions included inside the program have you dial *#0808#, but other instructions (like the ones on their website) have to go and install a bunch of crap to your phone and dial some other number, but I found the *#0808# will get you straight to the options you need to switch your phone over to DM mode. Also don't forget to switch it back to MTP + ADB (or MTP-only if you don't want ADB debugging on).
EDIT: also make sure you have a completely unfiltered network connection. I tried it on my work's "guest" wireless that has far fewer restrictions, but it blocks something within FastGSM's app that reaches out to their servers right before performing the unlock. It's a safety to avoid them handing out a bunch of free unlocks.
Also! I forgot that I didn't have a 100% success. It didn't unlock the phone by itself, but it did at least provide me the network unlock code. I manually entered this on my phone and it worked the first time. Don't try entering the code multiple times if it doesn't work the first time! Save a copy of the log it makes, but don't post it here (includes IMEI).

I have tried using their usb method and it didnt work and they give me full refund.
I tried free method many many many times with original firmware and the lastest and it failed everytime. I even got the unlock code from att and it also didnt work. I was able to get my phone replaced because of the unlock code didnt unlock the phone. They gave me hard time but i was able to get replacement.
The replacement had the latest firmware, so i didnt try the free method or usb unlock, i just got the code from att and it worked. The free unlock method def. does something that prevents the phone from being unlocked.

This is exactly how I have unlocked all of my devices on AT&T. I just chat with international support, tell them I am going out of country and would like to use my phone there. They ask for the IMEI and within a minute give me an unlock code. Never had anyone say no, and never had issues. Unlocked S2, S3, S4, Atrix. All phones except S3 purchased on contract and still no problems.
Idk why anyone would pay $35 for something that is so easy and free and the unlock code is guaranteed to work.

MF3 Sim Unlock Experience

For members who are on the MF3 firmware, what is your experience of Sim unlocking? It seems many are unable to sim unlock. Has anyone successfully sim unlocked, and how have you done it? I'm sure there would be a lot of members who would appreciate the feedback.
i buy my att s4 at full price and requested an unlock code from customer service, they gave me a 10 digit unlock code that worked fine, i am on the f*****ing mf3 firmware... thinking of selling the phone and getting an european version... will see later...
in the past i tested an unlock apk that brute force the unlock code, as it's a 10 digit code you could try that, it will take some hours of key testing, but you will get the code finally and for free don't remember the name of the application have a look on the play store or on aptoide
Cheers
I just did the chat with international care and they gave me the code.

galaxy s4 sgh I337 at&t unlock

Hey there, I have a samsung galaxy s4 sgh-i337 locked to at&t.
I bought an unlocking code from an ebay user.
it doesn't unlock my phone, it writes: "unlock request unsuccesful". I tried to use the defreeze code and then again the network code, still nothing.
I was referred to a guide that suppose to show me the "service mode menu", by entering *#0011# . so service mode goes on when i put that number in the dial pad, but then I suppose to do 'menu key'->'back'->'menu key'->'key input'->'1', but after I do that nothing happens, the service mode menu with all the options doesn't pop up, it stays in the same page of the service mode. somewhere down on the ServiceMode page it writes "Service:Limited". what should I do?

Someone... Help.. please
no Mega genius here that can solve my problem?
same boat here man, this is a new problem since not everyone has 4.3 yet. Att won't even give me the unlock code since they changed eligibility few months ago to "only off contract or fulfilled contract phones." I've read one person saying the eBay unlock code didnt work on 4.3 either. And the only success i've heard is another post here on XDA saying they unlocked 4.3 using the regionlockaway app, but they apparently Odin flashed 4.2.2, did the regionlockaway while the phone had no sound/wifi etc., then Odin flashed 4.3(locked again), then flashed 4.2.2 odin again, regionlockaway'ed, then odin'ed 4.3 again and the unlock stayed. That sounds ridiculous and is not an exact science.
So i'm done with At&t's phone slavery and switching to T-mobile on a nexus till the Xperia Z1 is out. I thought this was the future.

And the only success i've heard is another post here on XDA saying they unlocked 4.3 using the regionlockaway app, but they apparently Odin flashed 4.2.2, did the regionlockaway while the phone had no sound/wifi etc., then Odin flashed 4.3(locked again), then flashed 4.2.2 odin again, regionlockaway'ed, then odin'ed 4.3 again and the unlock stayed. That sounds ridiculous and is not an exact science.
So i'm done with At&t's phone slavery and switching to T-mobile on a nexus till the Xperia Z1 is out. I thought this was the future.

so what you're saying is that there's no future for these phones?

Take your phone to one of the shops which do unlocking using a box. It is possible to do it.

can you explain a little bit please? I am not aware of that method
how much do you think they'll take?
If you have another $20.50 go to Myhoian's website it's unlockcode247.com it'll take about a full day or over 12 hours usually but not longer than that he's never failed to unlock any of my phones.
I used region unlock. Unlocked my phone, put in a T-Mobile sim and it didn't asked for a code. Bam unlocked.

guys please explain, i'm a noob. what's region unlock? by the way, my phone is a GSM phone.
also, what's unlocking using a box?
and about that unlockcode247 - can they help me if I already got a code from another source?
I am not from the US and I want to use my phone outside of the USA (the phone was bought in the USA and is AT&T locked).

I used Cellunlocker.net and it was done in 24hrs. It did cost $29.99. Since I was on MK2 the only way to get it unlocked for free was through my carrier and they would not unlock.

My carrier said I was qualified to do the unlock. How are these services? Paying that much money on a limb sounds sketchy and most endorsers seem to be part of the sketchiness. Anyone else have experience using the only sites?
Jeez...

I unlocked mine using method 2. You will not have sound until you flash modem back. At least I didn't.

Unlock AT&T S4 to T-mobile

Hello,
I am sorry to ask this again but I have an AT&T S4 that's currently stock and runing 4.4.2 and I was wondering if there is any way to unlock it for T-mobile? I tired following some of the posts on here but they seem to be old and outdated. Does anyone have any other suggestions?'
Thanks!

I haven't heard anything yet..did more digging and it seems like you have to downgrade but then it's not guaranteed that you can unlock it.. I bought an unlock code for $30..still waiting to get it so I'll let you know if it works lol

If you are an AT&T customer or a previous member you can unlock your AT&T phone by going here. It is FREE and i have done it with all my phones so far. They provide you with an unlock code and all you have to do is insert the new non-at&t sim and enter the unlock code.

Yeah I am not an AT&T customer. I tried going that method and it didn't work. I got an unlock code from cellphoneunlock though

Since you have the unlock code, it will be almost the same thing. All you do is insert the non-att sim card and it will ask you to enter the unlock code. Enter the code and now you have an unlocked phone.
