Im confused about this whole downgrading situation.
Heres what i did.
Always use omega rom since i got the phone. So have gone from omega 4.2.2 to omega 4.3 to omega 4.4.2. Iv always updated bootloaders and my phone was originally on 4.2.2 MDE i think.
I decided to restore my phone to 4.2.2 and it worked however i cannot make or receive calls it freezes up the phone. So i tried to restore to 4.3 and odin gives a fail. So in the end i restored 4.4.2 changed the modem and used omega v12 on 4.2.2
What i dont understand is if downgrading is not possible why was i even able to flash the stock 4.2.2 firmware and why did i have these calling issues.
Any help?

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..

Actually, just odin the full mf9 tar file from sammobile and you won't have to do the OTA crap.

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

Can someone explain how to do 'Update Profile'?
Hello,
I have tried to downgarde S4 i337m Bell Canada from 4.3 to 4.2.2. Sam Mobile version - and the flash crashes at 2% (fails) using ODIN. Using Odin I can flash back to 4.3 and it works.
Is this an issue with the firmware file itself, or do I need to root and prep the phone in any other way?
I think the file is the cause, I don't see how the Phone's 4.3 would 'block' the flash.
Thanks,

I believe it is ALL S4's that took the updates to 4.3 and IF you try flashing back from 4.3 to 4.2.2 you can brick your phone. Check out the international S4 forums and see these results. The bootloaders do NOT ALLOW going backwards any longer. The same thing is happening on the S3's that updated to 4.3 as well. At least with the S3's they can still get a custom recovery and flash any Roms, including 4.2.2 based Roms that do not flash bootloaders.

Use mobile odin and flash the old firmware. MobileOdin does not flash bootloaders. Also I have seen 4.3 bootloader mixed with 4.2.2 firmware disables wifi for some reason.
Let us know how it goes.
Mobile Odin not working in 4.3 ....

I have Samsung Galaxy SGH-i337(AT&T) which I rooted and tried adding a twrp custom recovery which sent the phone into ODIN download. I was able to unbrick with flashing the 4.4.2 kit leak. The problem now is, it's not really the kitkat OS but still 4.3 which the phone came with but in about device settings it says 4.4.2. My question is, how can I get it back to the original OS 4.3? I have looked everywhere for on the internet for a stock 4.3 rom to no avail. Tried factory rest that does not work. I can however find stock 4.2.2 rom for my phone, can I flash it? Need help!!!!!
You should search and read before doing anything.

Never mind.
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

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.

Hey guys,
I successfully downgraded to MK2 from NB1 after taking the OTA update several weeks ago. I have rooted the MK2 and installed SS 3.72 with success on installing the recovery. I have tried multiple times following the guides on updating through ODIN to 4.4.2 again using GoldenEye and SkyFall and CM ROMs with no success. Each attempt ends with the phone not loading past the boot screen. It isn't bootlooping but pausing after the boot screen and not doing anything. What have I done wrong? I am getting tired of using this 4.3 rooted stock rom with no wifi. My data bill is going to be through the roof.
If you would have read the entire downgrade post you would know that there is a simple fix for WiFi.

I understand that there is a wifi fix for 4.3. However, that was not my main issue. I am trying to upgrade to a rooted 4.4.2 and followed the guide to a T as far as I know multiple times. Not having wifi between 4.3 and 4.4.2 was expected as I did not expect to be on 4.3 this wrong. I would really appreciate help on getting up to 4.4.2. The ROMs are not loading after the boot animations. Any ideas?
Nevermind guys. I decided to just revert back to stock 4.4.2 via Odin. I appreciate all the work by the devs to put up these guides for us to follow, keep up the good work guys.
