Trouble installing MK2 Roms - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

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.

[Q] New And Need Help

Hey Guys What's Up !!!!!!!
I an new so try not to bash me to hard.
I am trying to flash a custom rom to my AT&T Galaxy S 4 (SGH-I337) running Android 4.3 Baseband Version MK2
without any success at all.
I have root, I used saferoot and rootchecker says I have root as well as other apps, I also have rom manager premium v5.5.3.7. And paid for the touch option And here is where everything goes south.
No matter what I do when the phone reboots into recovery mode it boots into the standard android system recovery mode.( Manual Mode)
I see no clockwork anything.
I am dead in the water. Please Help.
The only modification other than root that I have done to the phone is change the tetherprovision.apk files with one I found out here
to reenable tethering. It worked like a champ (Sweet Thanks For That).

You would have better assistance here: AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshooting
Anyways aside from addressing thread maintenance to staff, to my understanding you cannot flash a ROM for the AT&T S4 MK2 bootloader. The bootloader is locked and thus making it impossible to flash a ROM. There is however a Safestrap Recovery recovery for your device but no ROMs.
The only recovery available for MF3 and MK2 i337 is Safestrap here:
http://forum.xda-developers.com/showthread.php?t=2448925
You can only flash 4.3 touchwiz roms. No AOSP or such. The number roms that you can install is also currently limited.

[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!!

Unable to update baseband/modem.

Baseband version is currently OA3.
No matter what I do, it's stuck on OA3. I've tried flashing the standalone OD2 modem and I've also tried ODIN'ing the full stock firmware. The baseband does not change. I even found a guide that says ODIN the stock firmware, root and run Triangle Away, then ODIN the stock firmware again. No dice.
Am I stuck on OA3 baseband forever or is there something I"m missing?
Try this, power phone completely down (pull battery out if you want). Boot into download mode and flash modem again.
Deactive reactivation lock if active

Check settings/security/Reactivation Lock, turn it off. Triangle Away hasn't worked since Jelly Bean. Also turn off Auto Reboot and F Time Reset in Odin.

Search how to flash firmware with Odin, simple stuff and it should get you out of your pickle
Fully aware how 2 use odin but not sure how that's going to help I've installed 2/3 firmwares to no success m8No m8
Do you not upgrade firmware through Kies.
Sent from my SM-N930F using XDA-Developers Legacy app
No m8 I don't really upgrade just either bang a rom on it or download firmware and odin it
Fully aware how 2 use odin but not sure how that's going to help I've installed 2/3 firmwares to no success m8No m8
Kies as in to fix factory mode .
You can download stock firmware from sammobile
These are odin compatible.
I had a similar situation when i flashed custom rom with latest twrp. (I used twrp 3.0) So i got stuck on download mode. After many searches i found how to use odin and flashed stock firmware. Then rooted it, changed recovery to custom and then flashed custom rom with twrp 2.8.7
Also provide your model no. and what you flashed so that more experienced guys can help you to come out from download/factory/odin mode.
Will do I've flashed a few bobcat and darklord to name 2 of them with same outcome I'll take screenshot on boot up

			
				
Just went ahead and googled for the heck of it... would "This" be a solution to your problem?

Would you know what would cause the recovery/boot program to update system - show Erasing after flashing ? Thx in advance!
I have a Samsung Galaxy S7 G930AUCUBCTB1 purchased in Colombia, I need help! I've upgrade it to 8.0 and the phone has signal, detects the sim but Emergency calls only. I want to downgrade to 6.0 but I cannot find the proper firmware that works. Any help?
