Sprint Galaxy S4 (SPH-L710)
Followed tutorial at
http://forum.xda-developers.com/showthread.php?t=2415587
to unlock SIM for GSM.
Experienced some difficulties on MDC flashing back to MF9, especially using links provided in the tutorial.
WiFi stopped functioning, couldn't make calls, and camera stopped working. Decided to switch from Stock to Cyanogenmod to see if it would help.
Used CWM, installed Cyanogenmod 10
WiFi worked again, Camera worked again, pretty much everything functioning normally, except:
Can't make calls, watch videos, do anything that produces or receives audio.
If I try to listen to music, I get errors saying the program is ending, especially saying DSP sound manager has stopped
Decided to try upgrading, upgraded to (currently running) 11-20141013-NIGHTLY-jflte
Android 4.4.4
Baseband: L720PUEMJA
Kernel version
3.4.104-Cyanogenmod-g52b4b50
[email protected] #1
Still can't listen to music, make calls, watch videos, record audio notes, use soundhound/shazam, the list goes on.
Basically, from what I can tell, the software just has no way to access the microphone and/or speakers, and won't allow me to do anything with the phone that uses them. I should add that everything else functions normally: SMS, internet, everything, all function as normal even on a GSM SIM card that I am now using in the phone.
Anyone have any ideas of how I can restore audio functionality to my phone? Obviously I know I did something along the way that affected this, but I'm not sure if it's with the modem, software, etc... Any and all help will be appreciated. If you need any more information I'm happy to provide it.
Hi,
Are you sure it's an L710? Cause that's an S3. If it is an S3 and you flashed anything made got an S4...that could easily explain your issues.
Can you confirm whether you have an S4 or an L710 S3 before I point you in a direction for help?
Thanks!

Sorry, yes it's an S4, SPH-L720.
In a bit of a hurry, so I typed 710 on accident.
To the best of my knowledge, I have flashed all S4-intended software to the phone.
In that case, I would suggest maybe you return to stock with Odin. If you need help, you can ask here,

And here is a very useful thread, your firmware for flashing with Odin is here as well, and much more...

One more question before I begin my journey back into stock ROM/Firmware:
When I return to Stock, do you think I will lose functionality on my GSM SIM card?
I've been reluctant to return to Stock mostly because I'm afraid it will "undo" the GSM/carrier unlock, which is basically the reason I started this process in the first place. I'm Studying abroad currently and for obvious reasons trying to keep the phone functional on a European (GSM) network.
You'd have to ask on the first thread I linked. ?
Thank you. Thread closed.
HI All
I have Rom'd the latest cyanogenmod (CM11 with android 4.4.4) on my phone. So it's rooted. Now I want to sim unlock. Even though I own the phone, Bell wants to charge me $50.00 to sim unlock it. This is ridiculous, and I refuse to give Bell more money.
So here are the questions I want to ask:
I have android 4.4.4 with CM11 on the phone. I want to downgrade to stock with android 4.2.2 - is there any reason why I can't flash the stock 4.2.2 rom
After I have downgraded, I want to use region lockaway. Then I want to go back to CM11 with Android 4.4.4 - will the sim unlock still be around
Can anyone tell me if doing the above will work?
Hi,
Don't mind the thread title, but you would be best to ask about that here,

Good luck!
Thank you. Thread closed.
Hello guys, I'm new to this community. I need help to unlock my Sprint Samsung Galaxy Note 3.
The phone was a gift from my friend since my nexus 4 broke. I'm currently on MetroPCS and I need
to activate my new phone, but since it is Sprint I havent been able to do it. I downgraded to Kitkat 4.4.2
and root it to install SSU. Since SSU was not working on Lollipop 5.0
So now SSU says that it is unlocked, but I'm still having the same issue with "invalid sim card." I read some forums
and they said that SSU works only for international, not sure if it works in US carriers like Metropcs. Lastly, I tried looking for unlock codes from paid websites, but they don't have offer any unlock codes.
I need some help with this, if you have a tutorial or know how to please help me. Thanks :fingers-crossed:

I have Note 4 from Europe
I have Rooted it and applied a nice cooked ROM from this great website.
Once I have install my SIM (first time since I have the phone), it comes with the SIM NETWORK LOCK.
Now, how com it is like that if i have ROOT and ROM not from Sumsung?
I need help on that as the prices out there are $35-$66
Can someone help? I have the IMEI and model (910C)
Many thanks to this great site and people

Hello, and welcome to XDA!
SIM unlocks are completely separate from actions performed by rooting, or installing custom ROM's, unfortunately. Also, you may find that if you get an unlock code, it will not work while running said custom ROM (I personally ran into this problem before). Samsung's are horrible for unlock code prices, but if you shop around you may find a good deal from a trusted source.
Ideas for that can be asked through the following thread, where your device experts are found:
> Samsung Galaxy Note 4 > Galaxy Note 4 Q&A, Help & Troubleshooting > [NOOB FRIENDLY] Ask the question!
Please note, you will need to have an XDA account to be able to post there.
Hope this helps, and good luck!
Hi,
New to the Forum but hoping that someone can help me.
I have a Samsung Galaxy S5 Active which I purchased off Amazon Unlocked. It is an At&t phone but I am using it in Canada on the Bell Network. I have been unable to get any updates and therefore am still running Kitcat 4.4.2.
I have downloaded the Bell Firmware but Keep Getting the Error Message "Secure Check Fail Aboot" Immediately after each attempt.
I have not been able to find an updated At&t firmware to load and as far as I can tell the Bell Marshmallow Update won't work because My Build version is G870AUCU1A..... Where as the Bell Build Version is G870WVLU1C.......
Is there a way to install this Bell Firmware on my phone ?
