Default Failing to Flash back to Stock

Hello Guys,

Model SPH-L720

Okay so I have been having nothing but issues with my AOKP roms I installed on my S4, I have no sound anymore phone calls dont work the phone constantly freezes and restarts.. nothing works.

I have been attempting to flash back to an Original Rom I have tried every ROM in Rwilco12's repo, nothing is working every time I attempt to flash it does this.

UPDATE:

- First issue I had when attempting to flash back to stock, I couldn't via ODIN on Windows without this issue.

- Second issue After I was able to flash the phone via ODIN Mobile I still had sound issues, I believe as daniel4653 stated you cant roll backwards I remember the last update before I flashed I was running 4.3 so I am guessing I was attempting to flash the device to Older Stock roms.

For that error when you are trying to flash via ODIN, I am guessing that only happens when you try to flash the phone to an older Stock ROM than it previously was running.
Try downloading one of the latest Stock ROMs and attempt to flash that, that should fix that error.

If the errors continue follow the instructions on Rwilco12's Repo and for flashing via Mobile ODIN, then reflash a custom recovery like TWRP after that is complete.
Reformat everything /data /system /dalvik etc... everything.
Then attempt to flash it again via Odin on Windows, and it should work that's exactly what I did.


What can also be done.. you can always download the modem separate via Rwilco12's Repo HERE and after flashing via Mobile ODIN, just flash this via ODIN on Windows and then you wouldn't have to reformat everything and reflash as stated above just for the modem to work, flashing the Stock ROM via Mobile ODIN doesn't flash the Modem so its required to be done manually typically. However if you are experiencing the sound issues like I was.. I would recommend following the instructions above and ignore this section.
