Has anyone successfully unlocked the SPH-L720 from Sprint with this newest firmware? I found instructions on another thread for unlocking the L720, but they are for Android 4.2.2 and do not work with 4.4.2. When I attempted to downgrade the modem, it bricked the phone. I've managed to get the correct firmware re-installed and un-brick the phone, but now I'm back to square one.
The phone is rooted, I just need to carrier unlock it from Sprint and remove the CDMA lock so that I can use a GSM sim (attempting to use the phone with NET10 which uses T-Mobile/AT&T compatible sims).
I'm having the same issue here. Let me know if you got through. I want to use my Galaxy s4 outside the USA on a GSM network.
same issue
I need to know also my contract is about over will sprint really unlock it for me I am rooted or can I go to a MDC baseband version and do the unlock codes....... please help ty

no problem this told me what to do http://forum.xda-developers.com/showthread.php?t=2415587 soon as I get away from my contract I will be trying thx
Bumping this to see if anyone has figured this out?
I've got a GoogleFi data only card and would love to get my S4 back online but it seems I'm SOL since I'm on L720VPUFNG2.
Someone on reddit said they figured it out but hadn't provided the details (nor replied to PMs), I don't want to brick my phone as it's still an excellent backup.
Is unlocking an L720 on NG2 possible?
Please I need this too
Have you guys tried the unlocking thread in the General section?

Hi Guys,
I just got my note 3 this week and I was thinking it'll be easy to have custom roms like my S2.
Totally wrong about that !
I managed to install custom roms after following instructions - X-Note build 15.0 N9005-ND5 which was to install Poland's firmware and then port over to the custom firmware... It booted up but i have no Network Coverage which requires me to insert a sim card which is already there........
I then spent countless hours trying to get it back and even went back to stock rom... but to no avail
Super frustrated and confused why has this happened..
Please help :crying::crying:

What about IMEI number? Type *#06# and see if it shows the IMEI number. If not your IMEI is corrupt, Do not give up just.

Good to here you got it working. But henceforth always remember to backup your EFS partition before flashing any rom. Though some Roms have the built in feature there are other tools available here on forum.

That's because it's referred to just by OA3. Why does he need a modem?

Here are the stock ROMs- http://forum.xda-developers.com/showthread.php?p=59310363
I would try www.sammobile.com for the firmware. I downloaded it from there before I had to return mine.
I had purchased an I9502 through olx.in, last week.
Second hand.
Due to rare users, there is no dedicated thread on XDA for my device
Now, many questions arises.
I had updated to official lollipop (5.0.1), by SAMMOBILE's official ROM. After upgrading, my second SIM cant connect to network. So I revert back it to KK (4.4.2). Still the problem persists !!!!! . I couldn't use it as a dual sim phone Is PDA and CSC version is important while flashing? or we could install any PDA/CSC rom version on samsung phones? I don't know the original ROM so, I had downloaded all firmwares available at sammobile and tested. only 2 of them managed to register my SIM(first) on network. Is it a hardware issue? or by a wrong ROM ? anyway now my mobile admitted at hospital and specialized doctors have been studying his disease
Is there anyone using dual SIM without any errors?
The PDA and CSC are vital to ensure you get the right regional variant for your device. The only exception is if the phone is unlocked for use on another carrier, in which case you can use a ROM from any region. Where you have the dual SIM version however, you only have one region available to you, but with multiple Android versions. The firmware here is the latest for your device. Do a factory reset before flashing through Odin.
I am totally disappointed.
My technician said that it had lost IMEI !

What will I do?
Is there anyway to recover its IMEI?
I had followed all guidelines available through search.
But, I couldn't...
Please help me on this....
Flash just the modem through Odin. You can extract it from the firmware download. Sometimes the modem needs to be flashed twice before everything functions correctly.
Other than that, I'm not aware of anything else software-wise that can be done. You'll need to take the phone to Samsung themselves and have them look at it.

I had the same situation and it worked
I have a few concerns to address. I recently bought the Galaxy i9505 (or in my case, the Sprint SPH-L720T version). The device comes unlocked with stock firmware/software, Lollipop 5.0.1 baseband OH2.
Now I will try to make this as clear as possible. We don't have the Sprint network here, I'm on Vodafone. I just flashed an official ROM from Sammobile with a different baseband version (this one) because I can't find the version that my phone came pre-installed with. I upgraded to address the StageFright and widgets app draw issue that was on the stock ROM.
Now my question is: by flashing a different baseband version, will I lose the ability to have an unlocked device and incur roaming charges on my network, or is the unlocked to work on multiple networks feature on a firmware level so I don't have to worry about it?
Thanks.

You will lose your domestic/international unlock of you upgrade the Baseband unless it was actually unlocked by Sprint.

Yeah, I kinda figured that would be the case. Good thing I made a backup.
I suppose you wouldn't know where I can get a StageFright Patch for the OH2 version by any chance?
So I have a sprint s4 onrunning octos (cm13 build) on 6.0.1. I have the OK3 already, as I came from 5.0.1 already using OK3. My question is, what modems can I flash BACK to? Better yet what firmware can I downgrade / flash ? I am having the worst time trying to get my network settings to work. The APN settings are COMPLETELY GONE. There is no way for me to edit them. And the best I'm getting of service is 2 bars of 3G MAX, when I usually get almost full bars of 4G here at my house. I struggled to even get 3g working. Can anyone help me out?
Sph l720 sprint running Octos CM13 6.0.1. MY PHONE IS ON STRAIGHT TALK. I REPEAT MY PHONE IS ON STRAIGHT TALK. THE SERVICE PROVIDER IS NO LONGER SPRINT IT IS STRAIGHT TALK.
But for some reason, when I was having the phone activated I was having trouble getting the sim to work. But they told me that was because it did not take a sim card with straight talk. Also they never told me to use the provided network access code. The phone was literally sitting there for 3 hours NOT ACTIVATED. Because they said it was in progress. I asked if it was taking so long because of the sim card not being inserted. They told me no. But for some reason as soon as I put in the sim card BAM IT WAS ACTIVATED. could anyone please help me out in some way
