I had issues flashing on custom Roms others had no problems but as soon as I went to my nandroid which was bone stock with cf root I had no issues... We haven't tested enough to figure it out ... There's just so many more variants to the equation unlike HTC.. I came from HTC as well and the s world is fairly different

As far as I can see, from the dates indicated on the download sites, the no aws and unlock AWS radios/modem files have been NOT changed/updated so you should be fine.
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
Yup exactly ... The files here are specific to north america so these files are the latest here... There are other radios that are newer then these but if course they were intended for the i9505...
[AT&T Samsung Galaxy S 4 Android Development] :
so, just wanted to add.. i was going to try switching modems today...HA big mistake. Lost my WiFi.

No matter what I flashed (carbon, kernel, modems) in Odin or Mobile Odin, no WiFi.

I tried the initial flash via Mobile Odin while running Carbon. Afterwards downloaded and flashed a tw ROM (fh 0.7 + faux 006m) ...still no wifi...but installed mobile Odin and after modem flash WiFi came back......I wasn't home at the time otherwise I would have restored a backup which included the modem (my sd card died two days ago, so I didn't have a backup on me...waiting on new card to get shipped...)

Just wanted to share my experience. Long story short, I don't recommend flashing a modem while running AOSP through mobile Odin. YMMV, but I know I'm not trying that again lol.
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
Did you try the WiFi fix big rig? Or going back to your nandroid?
[AT&T Samsung Galaxy S 4 Android Development] :
which wifi fix? The only kernel that booted 0630 nightly was k-toonez 0630 based off MFD/GE source...otherwise I would have tried an older kernel. I had tried the current CM and that KT build multiple times, but they are same source bases (not MDL/MDJ)

i tried the wifi fix for MF8 from 9505...it flashed in mobile odin, didn't fix it... on a PC with 1.85/3.04/3.07 it would not flash at Phone which is how it was supposed to be flashed apparently...

I was out when I did most of the troubleshooting, so didn't have access to most...I had the FH and kernel on my dropbox, no nandroid there though...should have put it up there...it was on my sd card that died the other day, and my computer at home...

But it does not work. Here is the complain message:

Hopefully the device reboot, but with the old modem working.
[AT&T Samsung Galaxy S 4 Android Development] :
for HSPA it seems slightly better on average....but maybe the effect is placebo. signal seems to be about the same (same dbm+asu). I do not live in a LTE area to check LTE speeds.

[AT&T Samsung Galaxy S 4 Android Development] :
No. I didn't have any success flashing via CWM/TWRP. I haven't had success with Odin on a PC, but I didn't try the new method (no auto-reboot, flash, reboot phone, flash modem again before letting boot).

Maybe if did flash but didn't change the version number reported on the device. I never lost wifi via CWM/TWRP flash though.

I only had success with mobile Odin. But last time I tried I was on Carbon (CM/AOSP base) and I lost WiFi until I flashed a TW ROM then installed mobile Odin and flashed a modem while running a TW ROM...

I was on the go, didn't have a nandroid..the nandroid likely would ahve fixed it too... i didn't have the space to make a nandroid either as I'm still waiting on a new SD card to get here and my internal is pretty full....

on that note....in the 9505 forum they say it's impossible to change the modem via ANY custom recovery....not sure how true that is though, that's just what I read.
[AT&T Samsung Galaxy S 4 Android Development] AlEjAnDrO812:

[AT&T Samsung Galaxy S 4 Android Development] AlEjAnDrO812:
Its not a prerequisite, you only change your modem if you want to try if the modem receive better signal... You can have any modem in any rom.. The only thing is that if you flash a modem with a different firmware you will have to flash a custom kernel

If you want to change your modem in 1337M variant you have to use the odin tar in mobile odin

In what variant? In att its supossed to change... Canadian variant you cant flash a zip have to use mobile odin with the tar

Enviado desde mi SGH-1337M usando Tapatalk 2
[AT&T Samsung Galaxy S 4 Android Development] :
lol, ya I don't want (or even like the idea of) software looking at what mods I make to my phone.

yes my version does change. it does NOT change when using the Zip files. In the 9505 forum they say you can't flash via custom recovery. Yet the AT&T version is supposed to work fine via custom recovery (looks like you have that version). it makes no sense...

anyhow, I use mobile Odin. choose open file, or manually put modem in both modem #1 and modem #2. thats' my preferred method.

you can also use normal Odin. disable the auto-reboot. flash the tar in odin, manually reboot the phone into download mode again (the 3 finger salute) and flash the modem again just like the first time (you can either enable auto-reboot or reboot it manually after)

Personally I'm not changing modems when I'm on AOSP base. I lost WiFi and all the kernels for AOSP are MFD based source now, not MDx based. so at the present you won't get a kernel that will match the modem to fix wifi if on AOSP base...
[AT&T Samsung Galaxy S 4 Android Development] fmark:
I flashed stock rom via Odin and for some reason it did not help. Modem is still showing the wrong one. Wifi is not working.

I'll try to factory reset the phone and flash stock again. This is unbelievable how difficult it is to get back to Stock firmware and modem...
[AT&T Samsung Galaxy S 4 Android Development] igotroot:
Honestly, when I had the Evo 4G (OG) and the Evo 3D we HTC owner used to enjoy easy flashing of ANYTHING once we had our root/bootloader unlocked......but your obviously are correct! I have been reading and reading and reading.....and still reading, about the S4 and how its so different than my old HTCs, and to this day its been like 4 weeks and all i've done is root my phone. Im still not confident enough to flash anything yet, but will as soon as I see my rom of choice get it's upcoming update.

So once again, someone (you) has claimed than even an Odin flash doesn't change the version of modem listed on the phone....wow.

Yes, I agree, and it is very frustrating at times. I had S2 before and it was much easier to move from one modem/firmware to another etc.

Anyways. I finally succeeded to get my WiFi and Stock modem back. Kies helped me here. I managed to flash i337MVLUAMDJ modem using Mobile Odin (Radio2).

Then I went to Kies and did 'Firmware Upgrade and initialization'. Then switched CSC to Fido using ( *#272*Phone’s IMEI # ). I then rooted my phone, Installed CWM and restored my Nandroid backup. I'll do my best to not to play with Modem again. :) Thanks for helping me!
[AT&T Samsung Galaxy S 4 Android Development] igotroot:
Not sure what I did to help, but your welcome LOL :p

So, Mobile Odin does in fact work on the S4, Cool.

I thought Kies was a phone to phone transfer thing by Samsung.

Whats CSC to Fido using ( *#272*Phone’s IMEI # )?

If we were discussing HTC, I'd be good. Samsung has me lost. So the fix for you was to put back a pre-update modem. Wow. I havent even looked at desktop odin neither.

So from what I read, there are two places with Modem data?
[AT&T Samsung Galaxy S 4 Android Development] fmark:
My thanks were for everybody who've helped or wanted to help (including you :)).

>> Whats CSC to Fido using ( *#272*Phone’s IMEI # )?

This changes operator specific settings (including bloatware). Original Stock rom that I've downloaded had Bell's CSC and my phone is from Fido.

Nothing serious actually, just wanted phone to be the way it was before I started to play with modems.

>> So from what I read, there are two places with Modem data?

This is an option in Mobile Odin. Normal Odin has only one modem choice. The problem was that normal Odin failed to flash my stock radio, but Mobile one did when I flashed it as Radio 2.
[AT&T Samsung Galaxy S 4 Android Development] igotroot:
Thanks.

So for future reference, Mobile Odin will flash the zipped modem file, or does it require a different format? How does it recognize where to put the modem in?

So is that *#272*Phone’s IMEI # a standard command on all variants of the S4 or just for Fido (who is Fido?)
[AT&T Samsung Galaxy S 4 Android Development] fmark:
Mobile Odin is using the same files as a normal Odin. You just put your modem in the Modem (and/or Modem#2) sections of Mobile Odin and flash.

>> So is that *#272*Phone’s IMEI # a standard command on all variants of the S4 or just for Fido (who is Fido?)

I don't know if CSC switching with *#272*Phone’s IMEI # work on every phone. I know it worked on my Canadian S4 (from Fido - my mobile operator).
