[Q] Opinion/Suggestion on upgrading modem and baseband on AT&T S4 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Dear All,
A year ago, I bought the AT&T S4 SGH-I337. The android version was 4.2.2. Before I activated the phone, I rooted with motor chopper. The phone came with MDL baseband and modem. Before the MF3 OTA, I flashed the Clear Rom 1.0. Later I upgrade it to Clear Rom 1.5. The phone stays at MDL.
A year later, I want to upgrade to Kit kat so I flashed Golden Eye 29. Wifi and phone works fine. Except the occasional application freezed up in some app the phone was fine.
Today, I flashed Golden Eye 30. My baseband and modem still at MDL.
My question being... Should I upgrade my baseband and modem to the new version or just stay at MDL.
If I should upgrade my baseband and modem which version do you suggest?
Thanks in advanced,
Andrew

Stay on AMF. It's the only one where you can install loki and flash any roms to your hearts content! Otherwise you won't be able to install non TouchWiz roms.

Updating the modem alone using the recovery flashable zips won't upgrade the bootloader, so that's not an issue. Just don't try to use ODIN packages to do it. You can experiment and see which modem works best. The thread for them is in the general section.

How to update baseband/modem

I've been flashing ROMs since I got my phone many months ago but, despite flashing CM10.2, Omega 13, Slimbean build 2, etc... it seems that I still have the MDC baseband.
How can I find and flash an updated modem?
I ask because I don't get 4G or LTE on slimbean or Omega and others indicate that they did. I am hoping that an updated baseband will get them working.

Odin back to mdc unrooted and catch the otas to mf9 then use cf auto root to root, do a nandroid backup and flash whatever rom ya want. Thats what id do. I get lte on slim and all aosp roms..

So I Odin'd the MF9 baseband, that didnt help.
Then I Odin'd the entire MF9 ROM - THAT STILL DIDN'T HELP!
Even in stock MF9 I didnt get 4G. I was going to bring it into a sprint store but on a hunch i went to Update PRL (that didnt help) and then
Update Profile - Voila!
So, if anyone else has this problem, flash back to stock and do an "Update Profile."
I have since flashed back to SlimBean and retained my 4G. Still have no idea how I lost it but I'm glad it's back.
here you go bro (link below), Hope this help's it did for me, cheers

[Q] S4 / can I downgrade?

I have a S4 on MK2 on AT&T
The fact that I am stuck on TW is depressing. And to top things off AT&T has disabled WIFI tethering, which I was using occasionally.
Is it possible to ODIN back to stock and the firmware the phone came with a year ago?
Is it correct that the originally firmware would allow me to flash Cyanogen / Task etc?
What firmware do I need to get? I understand MF3 is also bad?
You cannot downgrade.

As stated above, you can't downgrade. You can enable tethering by the thread in the general section and use Safestrap to change to other TW ROMs like Foxhound which has AOSP theming.

You could only downgrade from 4.3 if you were using the leaked 4.3 ROM with the MJB bootloader. The official OTA 4.3 updates cannot be downgraded as Samsung blew a "qfuse" with this major (4.3) update preventing reversion of the bootloader.
However, you can change or downgrade the actual ROM filesystem, provided that you keep your MK2 boot loader in place. That means that you can't revert to a pre 4.3 stock ROM but you can use custom ROMs that are 99% stock while restoring the functionality that you'd like to restore.

Returning to stock australian 9505

Hey guys was hoping to get a little help. I am currently running foxhound 4.1 on my S4. The baseband version is I9505XXUFNA5. Its OS 4.4.2. In the process of flashing this rom according to the instructions on the dev thread said i had to flash a different bootloader and modem before flashing the rom. This process worked fine and i have been running without issue. Work has now decided that they want everyone on Android 4.3 so we can use apps they made to make our job easier so i need to go back to 4.3. I attempted this last night and when i try to flash a 4.3 rom via cwm it returns an error saying that the bootloader is the incorrect one and fails and i have to reinstall foxhound again to make the phone usable. Any one know how i go about getting back to 4.3 or where to get the correct bootloader and modem so i can flash them via odin and then install Androind 4.3? Any help would be very much appreciated.
Cheers Jeff
Nobody can downgrade from 4.4.2
WTF really?? Cant i flash 4.3 bootloader and modem and then go back to 4.3?

Nope not at this stage cannot downgrade to older bootloader, sorry.
The best you can do is install a 4.3 custom rom. Try an echoe rom, version 12.1 the final bean I think should do.

Has anything new come around in the last 6+ months?

4.2.2 / MDL here. I'm rooted to freeze the metric ton of bloatware/greenify/xposed. Didn't get into ROMs because I'm afraid of bricking my only phone.
Been sidelined for several months with health issues, wondering if there's been any new stuff down the pipeline or if I should stay at 4.2.2/MDL? TIA.
Sliced bread has come out. Jk, given the time taken for someone to answer you, nothing new has come out that's earth shaking. Other than new firmware. If everything works for you it probably isn't worth upgrading.
You're on mdl which allows you to flash a number of different roms which you aren't taking advantage of. The latest firmware, nc1, is rootable with towel root. You can flash touch wiz based roms but that doesn't seem to be an interest to you So you might consider updating to nc1 if you want the latest firmware. But many people would like to be in your shoes with mdl firmware.

If you have root and custom recovery (TWRP or CWM) and want to update to newer firmware I would suggest Sho-Stock-i V7.0 Then you w I uld have the newest firmware without having to use Safestrap and be limited to what you can do with your phone.
I would STAY AWAY from updating to the newest firmware (stock firmware) NC1 as right now you can do ANYTHING you want with your phone. That is why I suggested ShoStock to have the best of both worlds. Personally there is NOT MUCH different between your MDL 4.2.2 firmware and the newest 4.4.2 firmwares. Maybe a little smoother.

Would reception be better with 4.4.2? We recently took a road trip and on a very long stretch my hubby on 4.4.2 had coverage the whole time while I had 0 service for about 1/2 of the stretch. Other areas he was pulling data fine while my phone showed no service or a G and up and down arrows which was completely new to me. It's bizarre.

I don't think I have recovery? I only remember rooting, no option for twrp or cwm. Am I hosed now?

If you are still in fact on MDL then you can get TWRP or CWM recovery and flash as I stated above. You can use ShoStock-i once you have a custom recovery. First VERIFY you have MDL bootloaders. Then if you do look into "Motochopper +Loki" which will give you the custom recovery. Then flash to ShoStock-i. Then you can flash any of the modems in my thread to find which works best for your phone in your area. Maybe see which "baseband" (baseband=Modem) your husbands phone has (if it is also a i337 S4).

do you have a link for the Sho-Stock-i V7.0? I can't find it? Also would any version of CyanogenMod work? I can't find one that would work without me upgrading to 4.4 if my google searches are correct. Sorry for the delay in replying... health issues are a PITA.

You do NOT need to update to run ShoStock. Just flash his newest in recovery (TWRP/ cwm/etc.) It will give you the newer firmware of 4.4.2 but NOT give you the 4.4.2 bootloader. So you can always flash back to your MDL stock firmware via odin. Like I said, the best of both worlds. Keeping the bypassed bootloader while running newer firmware. Just use ShoStock 8.1 (NOT THE SAFESTRAP VERSION)

[Q] Upgrade SGH I337 to Andriod kitkat

Hello,
I have samsung SGH I337 phone and its not rooted. I bought this phone in Sep 13 and unlocked with some code. Currently its stuck at 4.2.2. and I want to upgrade the phone to latest 4.4.* . As I unlocked the phone, this stopped getting update from ATT and dont show any available updates.
Can someone share the process to upgrade to latest kitkat ?
First, if you're on mdb or mdl firmware you might want to reconsider upgrading. If you are you have the ability to use twrp or cwm custom recoveries and easily flash roms
But if you still want to go ahead and update then flash the nb1 tar file in Odin http://forum.xda-developers.com/showthread.php?p=50912149
This will wipe your device so backup anything on your internal sdcard. You will not lose the sim unlock.

My S4 build number is JDQ39.I337UCUAMDL.
Forgive my ignorance but can you tell me what is the significance of mdb or mdl firmware. Also does upgrading the Android would create any issues on my phone.
Need one more information on Kitkat version i.e. which kitkat version is stable and has no issues.

You're on mdl firmware. There are users here who would love to be on that firmware version. Being on mdl allows you to run custom recoveries. With newer firmware you can only use safestrap as a custom recovery which limits what you can flash.
Edit, once you go to nb1 firmware you will not be able to go back to mdl.
But you said you're not rooted and have not run custom recoveries. So if that is not important to you then flashing the nb1 firmware will up grade you to 4.4.2 kk.

If you upgrade to 4.4.4, and want to flash custom roms you'll have to use safe strap. If you keep 4.2.2 you can flash 4.4 roms also. I wouldn't recommend updating, but it's your choice.
