[Q] Odin OD2 --> NG2 Possible - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I'm currently on Lollipop OD2, and rooted. Using Odin, can I take the stock NG2 tar and downgrade back to stock Lollipop 4.4.2?
I am assuming it's possible but wonder if the modem/kernel will also make the downgrade appropriately.
Any thoughts?

You cannot downgrade via Odin.

So I guess I should look for a NG2 Rom then, preferably as close to stock as possible, and then flash it via recovery, correct?

Yep

It doesn't. he'll need to flash MK2 as you suggested, use Safestrap, and use the KitKat Magic Toolkit for a 4.4.2 ROM.

[SOLVED] i337 Flashing Modem from MK2 or MBL to NC1?

[Q] i337 Flashing Modem from MK2 or MBL to NC1?
Hi,
My phone build number is i337ucufnc1 and my original baseband version is i337ucufnc1.
However, after following this tutorial "Possible method to SIM unlock on MK2 *must be rooted*" Method 2 , my phone was sim-unlocked successfully but now the baseband version is MDL (and I flashed MK2 later and it worked) I couldn't go back to NC1. I flashed it with I337_NC1_Stock_Kernel.tar.md5 but It didn't work.
Edited: I forgot to mention that the Wi-Fi is not working.
Can you please guys guide me on how to restore it back to NC1?
Thanks!
Have you tried doing a data factory reset in recovery? It may not help but worth a shot. Try it after flashing NC1 again.

I am about to try to flash it with the combined MK2 tar (found here)
Edit: It failed.
I tried to root it using Towelroot/Saferoot/Kingo Root but none of them worked.
Dude that is really odd, I have no idea as I have not come across that problem. You tried flashing NC1 and MK2 with odin and no dice? Have you tried flashing the NB1 .tar?
In order to root you need to flash the NB1 kernel I think it is, but if you flash the entire NB1 stock .tar file it should flash the kernel too.
Alright, I flashed it with ALL_ATT_I337UCUFNB1_I337ATTFNB1_505595_REV06_user_low_ship_MULTI_CERT.tar.md5 in Odin and it worked like a charm! thanks a million!!

Trouble installing MK2 Roms

I have a Sprint Galaxy S4, and previously I had the Echoe Galaxy S5 port Rom on my phone. It worked great until I got a new number that needed to be programmed to my phone. Since this Rom isn't optimized for Sprint, it is missing the update data profile setting, and the dialer codes for sprint such as ##update# and ##72786# I would normally use to reprogram the phone doesn't work. So I decided to install a different Rom and I installed the Triforce S4 rom with MK2 modem. But with that modem after the Galaxy S4 splash screen the screen goes black. So I had to go back to the echoe rom that doesn't work.
How do I install a MK2 Rom without my phone freaking out?
Odin the NG2 tar, flash the ROM. I don't recommend trying to downgrade firmware.

Is NG2 the latest modem? I've been in a terrible string of unsuccessful fixes. I've soft bricked it because one of the modem flashes didn't go through, so it shows the missing firmware error when I boot it up. Download mode works, but recovery is dead at the moment...
Yes, it's in the Android Development section, flash in recovery mode through Odin.

Cool. I found a stock NG2 tar. I flashed the NG2 modem and I'm in the process of getting the rom installed via odin. It has made it a lot further than my other attempts, so I think it's good. I guess I was just trying with the wrong modem before.
I'll just have to reroot, but that shouldn't be too bad.

Can't downgrade your firmware, but you can flash any KK ROM.

KitKat (4.4.2 and 4.4.4 are both KitKat, 5.0 is Lollipop or LP for short, 6.0 is Marshmallow or MM for short, etc)
ROM is short for read only memory, try Wicked X, that's my ROM (there's a KitKat and Lollipop version, so make sure you get the KK).
