Hi I am struggling to sim unlock my SPH-l720 so that I can use it with cricket, I've tried all the sim unlock methods and can't seem to get it to work.
MF9 -> MDC changed the servicemenu settings and what not
Everytime I try to simunlock I just get a "SIM card not found" error, nor can I edit my APN settings even after adding the two lines in the build.prop editor. I also notice all the guides are using 4.2.2 firmware, which I'm not sure how to downgrade to, or if that is even possible.
Downloading an APN editor lets me add a new APN, however it never saves.

Ok so i rooted the phone.
Unlocked sim from srint to rogers in canada
And no data obviously.
I know i have to enter the ##data# code, but it will not work since it is on 4.2.2,
I get the 6 digit code but the phones reboots because it will not accept the code.
I tried as well to change the build code but when i try to save, it gives an error code.
I did the mf9 radio change over as well.
The phone works but no data.
I have read all the posts, but to no avail.
Am i blocked for real, or should i install an older series instead of 4.2.2. And try it all over.

I have the same issue and I am using an App ( APN Setting Shot Cut) to work my data
I hope there is not a super obvious solution I missed somewhere, I apologize if I am hasty in posting this question, but I cannot understand why my AT&T l337 is not working with my Canadian mobile carrier, Wind Mobile. I do not get the network lock screen with the pin/dismiss options, and the phone picks up on signal, but it gets no data and still prompts "emergency calls only" when I try to make a call.
Phone is rooted stock 4.2.2 NC1, safestrapped, with an MF3 modem. I got the phone new when it was already on NB1 in May 2014, so the service menu unlock method was obviously not an option. I followed the steps in method 3 (@NewToGalaxy) from the @bvzxa3 "possible method to sim unlock" guide, http://forum.xda-developers.com/showthread.php?t=2595457, it does not seem to do anything but remove the initial "pin/dismiss" network lock.
I tried enabling AWS using the "enable AWS on AT&T samsung S IV" @zaryan guide (http://forum.xda-developers.com/showthread.php?t=2291589), but when I try to enter the *#7284# into the dialer for step 3, I get the same "Connection problem or invalid MMI code" I get when trying to use some of the options in the *#0011# service menu.
I have searched around XDA, but I did not find anyone who was experiencing the same issues I had. What am I doing wrong? Flash the MF3 modem, run regionunlock, insert non-AT&T sim (and all the combinations of steps therein). How can I enable AWS if my phone can't access those service menus?
Based on the information cloud-x provided in his sim-unlock thread http://forum.xda-developers.com/galaxy-s4-att/help/i337-sim-network-unlock-assistance-t2808211, it seems like receiving an unlock code from AT&T is not an option since I'm only three months into a contract, and normal unlock code vendors may not be able to pull codes. At any rate, I am in Canada for a limited time and I hope to solve this issue before I return to the states and cannot test my Canadian sim.
I'm sorry I'm kind of a noob and if this situation or issue has been dealt with before, I just hope someone can point me in the right direction.
http://forum.xda-developers.com/showthread.php?t=2285431 follow the state at the beginning of this thread after rooting and installing shortcut master lite use the secret code explorer and scroll down to code 27663368378 there you will see all the options needed. I was on NC1 when I did this
I337 stock NC1, rooted, unlocked
Sm-T537A NE1stock, rooted
Ok this is the 4-5 Sprint Galaxy S4 factory unlock i have done. but for some reason this one will not work on metro.
here are the steps i followed
Phone was stock NG2
i factory reset the phone and installed the MDC Modem
i then did the internation unlock and then the domestic unlock.
after i did all this it will accept all sim cards but it gets no service with my activated MetroPCS Card.
so i changed the APN setting and still nothing so i called to metropcs and they said they needed to add the imei to my account. but when they try they say they can't add it to there system that the unlock did not go threw all the way.
so i then rooted the phone and installed CM nightlies rom and still can't activate it anyone have any ideas on what i can do and why they cant add the imei number to there system
no one has any ideas. could it of been because i was on NG2 rom with MDC modem should i of rooted and installed a rooted MF9 rom and then install MDC modem then run the process. any help would be greatly aprecaited
Could be that the imei is blacklisted?
that was the first thing i checked and everything came back clean on 2 different websites
OK, I finally got Sprint to uicc unlock my phone yesterday. Now I need to figure out how to change carrier options., any help would be greatly appreciated. Also now that it's carrier unlocked shouldn't I be able to access the hidden menus and stuff or can I only do that after root?
No getting unlock didnt change anything. It just unlocked the uicc slot for a different sim. Have to get another sim and pop in phone and then you can set ur apns for that network.
Nothing else gets "unlocked" and is nothing near the access root gives you.
That's what I thought ugh. But I've tried to do that and can't get the APN to save.... I've tried to edit it with##debug# I have my msl also. And I also like I idiot purchased a unlocking app off eBay and all it was is hidden menu apk. You can add APN with that but still don't save. I inserted my Verizon sim card in the phone and it shows me roaming for service. I'm going to root my phone hopefully tomorrow afternoon. Once I do that the way I understand it that I'll be able to change and access more things. Sorry I'm a newbie when it comes to rooting, can do a lot with phones but some stuff is all new learning experience

Dont need to root.
If you have msl you can use cdma workshop or another efs program. Need to change ur prl to a vzw one. Then set apns.
Root will fix the issue with apn not saving as the hidden menue stuff needs root to activate the right menues.
But you should be able to swap prl to vzw one and put in sim and do *228 to activate. But rooting will make easier.
Root and flash a vzw rom and profit instantly lol
Quick question? i have the vs997 and i rooted and flashed the vs996 to utilize my Verizon sim. I am able to access and edit apn settings, lte and such work fine but are you saying i could flash a verizon rom to this vs997 so i dont have to use the vs996 rom with the debug kernal?

OK I'm want root also cause I want to tinker lol, I love messing with the different menus and stuff. I'm kinda nervous to root cause will be first one and don't want to make expensive paper weight.... But I ran into some issues the other day with trying to root but didn't know needed SD card and couple other things. But like other guy said I can flash the VZW ROM and be golden? Also will I pick up all the band's that VZW towers put out?
Trying to use straight talk in Verizon s10+. Adding apn is grayed out. Any help is greatly appreciated.
In order to unlock the APN menu on a Verizon phone running Oreo, I had to insert a friend's T-Mobile SIM card and it let me change the settings. The new settings stuck after removing the SIM and reinserting the Verizon MVNO SIM card. Otherwise, it would not work.

it works just fine on combo and even stock vzw afterwards if you enable keystr and hiddenmenu on efs partition while on combo
to add, if u kno how and have the files i recommend not changing the mps and omcnw codes as they will stick when going back to stock and u might need to start over lol
the attached screens are from a vzw g975u
