The phone needs 4.1.1. Once on 4.3, the bootloader is locked and the ROM can't be downgraded.
[AT&T Samsung Galaxy S 4 General] gerardfraser:
Sim Unlock Samsung S4 i337 Android version : 4.2.2

[MENTION=4673498]audit13[/MENTION]

Your post #713 was very helpful and with easy to follow instructions.

I have never touched a cell phone or owned my own phone.Brother bought locked Samsung S4 i337.I did a search and did some reading and in a couple hours the phone works great with his sim card.I hit the thank button.

How to flash the 4.2.2 modem and sim unlock the phone:
power off the phone;
Open Odin 3.10.7, uncheck everything except auto reboot and f.reset time;
click on CP in Odin and browse to the modem.bin file (changing the file name may cause Odin to fail, thanks to @droiduzr2 for this hint);
put the phone into download mode and connect it to the computer via USB cable (I recommend using the USB cable that came with the phone and a USB 2.0 port, not a USB 3.0 port);
flash the modem;
when the phone is booted, locate the regionlockaway.apk file, install and run it (this will remove the sim lock);
power off the phone.

Thank you Again

The phone must be running a stock 4.1.1 ROM in order to use the dialler method.

This means they know which version your phone is still, correct? I was thinking maybe carrier unlock made it think it was an unlocked phone so it wouldn't give you all that bloat:(
[AT&T Samsung Galaxy S 4 General] :
The bloat is like in a partition for the phone. Which you can't mess with till a bootloader unlock

[AT&T Samsung Galaxy S 4 General] :
You can use titanium backup to remove it though. It'll just come back with a restore.
[AT&T Samsung Galaxy S 4 General] DespairFactor:
remove the entire partition or?
[AT&T Samsung Galaxy S 4 General] :
The bloat apps. They'll be gone but they will still be in the partition so that when you restore it it reinstall the bloat and the phone restores everything as if you just bought it.

So how did you guys change the band's to work on t mobiles 4g network? I'm getting and at&t s4 soon and want to use it with t mobile
[AT&T Samsung Galaxy S 4 General] MrHomebrew:
Is there a way of re-locking turning back on the shaw255 or whatever its call? I dont remember exactly what it was called.

A reverse method to re-lock could also be useful, maybe for waranty purposes.
[AT&T Samsung Galaxy S 4 General] scott14719:
Unlocking your phone will not change the terms of the warranty. Many varieties of the S4 are sold unlocked already.
[AT&T Samsung Galaxy S 4 General] JoJo2211:
How are you guys able to unlock it fallowing the OP's method? I've tried twice, the phone reboots as OP says but when I put my tmobile sim in it asks for unlock code.
[AT&T Samsung Galaxy S 4 General] MrHomebrew:
So yoyr saying if I purchased the phone then unlocked I would not be voiding my warranty?
[AT&T Samsung Galaxy S 4 General] moobieboobie:
same issue for me. my brother has tmobile and i've tried this method like 10 times to no avail. as soon as i boot up the tmo sim, it says invalid sim and ask to enter unlock code.

also, unlike the pictures posted on this method, i get another option that says [4] RAT_FREE_SUPPORTING
[AT&T Samsung Galaxy S 4 General] scott14719:
Once you "restore the Golden Backup", you shouldn't be able to do it again. The next go around should tell you that a backup doesn't exist. Did you see this?
[AT&T Samsung Galaxy S 4 General] skedi:
I tried this on a Bell/Virgin I337M. May be I screwed it up the first time, but inserting a Fido Sim did not work form.
[AT&T Samsung Galaxy S 4 General] moobieboobie:
yup. it says a backup exist every time i've tried it. i'm familiar with the process as i've done with my friends S2 and not problems. so i don't know whats happening.
[AT&T Samsung Galaxy S 4 General] scott14719:
Yep, mine says, "golden backup not exist...cannot use menu [4] and [5]" or something close to that. So I would say for some reason your phone isn't restoring the "Golden backup"
[AT&T Samsung Galaxy S 4 General] ethem11:
it did not work for me i followed everything but it keeps saying sim network unlock pin i have att s4 i337
[AT&T Samsung Galaxy S 4 General] gaguzman:
Same here. To confirm if I'm doing this right: phone app, punch in digts #0011# ,then touch the offhook symbol. I get a

dialog box just like that and no menu. Tried the other numbers in associated threads. Same results. Is there supposed to be a message before the menu comrs up of any kind?
[AT&T Samsung Galaxy S 4 General] ethem11:
you should put star key before *
[AT&T Samsung Galaxy S 4 General] scott14719:
You are not doing it right.

punch this in on your dial pad exactly:

*#0011#

after the last symbol is entered it will automatically go to the hidden menu and then you follow the rest of the directions.

Anyone successful with a Rogers S4?

I have tried this a number of times with my S4 from Rogers with no success. I follow all the steps and reboot (everything appears to work). I then insert an Orange SIM and get prompted for the SIM network unlock PIN.

If I tried to repeat the operation without inserting the Orange SIM then I get the message that the Golden backup does not exist.

I would appreciate it if someone could tell me if they have been successful with a Rogers S4 and if so, whether there are any variations that need to be performed?

Thanks

Hi, i also have a Rogers S4 and it doesn't seem to work for me either...

I tried pretty much everything since yesterday and i still have the "SIM network unlock PIN" message.

Thing is, if it works on Telus, it should work on Rogers as it's exactly the same phone.

I had the "Golden Back-up Exists" but even Restoring it didn't work...

So if someone on Rogers was able to unlock it, i'd be glad if he/she can explain how he did.

Do you need a special sim card to get LTE with Telcel? or just a regular 3G Telcel micro sim card?

You need to continue and follow the last two steps:

Step 7: Now, you need to get back to Main Menu. To do this, hit the Menu button followed by the Back key. In Main Menu, now pick [6]COMMON, and then [6] NV REBUILD.

Step 8: The phone will tell you that a Golden Backup exists. Tap [4] Restore Back-up.
[AT&T Samsung Galaxy S 4 General] rfb813:
Did all that and still no results! I have a other Sim Card which works in my S3 but when I place it in the S4 I get the unlock key request

I have done this numerous times with no success. I am concerned now that I have done this it will not work with a unlock key from ATT. Normally if you try more than 4 or 5 times the phone locks itself.

[AT&T Samsung Galaxy S 4 General] Thermalwolf:
I think it's a combination of whether or not you have the 16Gb or 32GB on top of your firmware version and where it was manufactured. These menus have little differences between small hardware builds. Very specific stuff.

All these different reports from people in att where for some it worked and for some it didn't. I'm wondering if it has anything to do with where the pound was made. Some were made in China and some in Korea. The same where people with s4 made in China are reporting lag.

---------- Post added at 01:53 PM ---------- Previous post was at 01:51 PM ----------

I think that means that the sim card isn't activated or it isn't good anymore. But as long as it didn't ask you for the unlock code you should be unlocked.
[AT&T Samsung Galaxy S 4 General] ethem11:
I tried 2 diffirent phone several times. They are brand new att s4 usa. First phone, i did everything correcly but after rebooting it was asking unlock code. Second one, i did everything same like before and this time phone did not ask unlock code but it was saying emergency call only with my t mobile sim card. When i put my att sim it is working fine. I guess what happened is that maybe if you enter 10 times wrong unlocking code phone lock itself with whatever carrier it is. My guess is phone locked permanently on att network. So people be careful. probably something different for my first phone. it is still asking unlocking code though
[AT&T Samsung Galaxy S 4 General] milicigoran:
No I don't mean usa version. I mean where the phones were made. The s4 was build both in Korea and China. It says it on the box. Mine is made in Korea but some were made in China. The Korean ones seen to be built better. The China ones seem to have lag. And I'm wondering if the same applies for the unlock. You can unlock using this method the Korean one and not Chinese or the other way around.

[AT&T Samsung Galaxy S 4 General] dmplus:
I think i've noticed a common thread in those who do not have it working. It may be that you have to have a functional native network sim installed when you do these procedures. I'm not sure if it will work if there is no sim installed, or if you have a non-authorized sim installed. But I have done this twice on both t-mobile and ATT variants and it works.

[AT&T Samsung Galaxy S 4 General] scott14719:
Close to the same here. I posted earlier about the process working, but I went to my local mall today and got a T-Mobile pre-paid Micro sim. When I put it in the phone I got the "enter unlock code" as well. I went back into the setting, set it to "SHA 256 ON" and got a code from Cellunlocker.net. It cost $25, but I got the code in under 5 minutes. Put the T-Mobile sim back in, entered the code, and was unlocked. It was worth the $25 to me to get it actually unlocked.

It is strange that it works for some phones and not others. If I had to guess, I would say it has to do with the "SHA 256 ON/OFF" settings. I followed the OP directions exactly "SHA256OFF" and it acted as it was supposed to. After I restored the "Golden backup", I noticed that the backup didn't exist when I checked it again. However, when I changed it back to "SHA256 ON", a golden backup did exist. I didn't try to restore it again because I already had my code from Cellunlocker.com, but I wonder if I had restored the golden backup with "SHA256ON" if it would have worked then?

Oh well, at least my phone is sim unlocked now.

If the carriers had their way, rooting would be illegal. Considering that if you bought the phone on contract it also came with an ETF clause, I'd call it even.
