Ok, you must be wondering why the heck anyone would want to downgrade from 4.4.2. Well I had one noob moment and a couple of unfortunate coincidences. I haphazardly flashed a rom for an I9505g onto my phone. Luckly I can still boot up and connect to my wifi. If I turn the airplane mode off then the phone goes haywire. Im sure that isnt fixable.
My difficulty is finding a stock 4.2.2 ROM to flash.
I would just flash the recovery i have, but, it somehow is corrupt and sends my phone into a bootloop so i have to reflash the 4.4.2 again to get anything to work. Really, i think all i need is a link to get me going in the right direction for the files i need. If anyone could hook me up i'd really appreciate it.

I rooted my AT&T Galaxy S4 i337 a while back using Motochopper and it worked absolutely fine. After installing Cyanogenmod, I decided to go back to stock. I used triangle away and Odin to return myself back to stock, however, I always had issues. When I would recovery boot, I got an error and I couldn't wipe my cache partition. I tried to re-root my phone today using Motochopper and then Odin, but neither of them worked. I got a fail on both of them. Motochopper installed Supersu on my device, but didn't actually give me root access, and Odin just gave me a fail. Now, my phone is working with stock, but I still get errors in recovery mode and I can't root. Can someone please help!?

That's what i was afraid of. With mf3 you can't root with motorchopper or flash roms like you could on mdl. You also can't put on a custom recovery. Give me a second and I'll give you some links.

MF3 has a completely different root and recovery method now. Search the threads and you'll find them. Unfortunately it's pretty risky as you won't be able to flash back to stock using ODIN on MF3.

Because you were on mdl firmware. After you Odin'd it had to have taken the ota update to mf3.

Ok, so I read the links. Now, I'm not so much interested in rooting as I am getting my phone straight. Is there any way to get back to mdl? Will the rumored 4.3 update this month fix that? When I tried to update or recover with Samsung Kies, it said my phone wasn't compatible to recover. Does that mean I won't be able to get the update?

First, there is no way to go back to mdl. Idk if you'll be able to get the 4.3 update but I would assume so since you are on the stick firmware now. But, each new update is going to make it harder to root your phone or run custom roms. So you probably need to choose whether you want to keep your phone stock and take updates if and when they come out. Or have some snooty to run custom roms and root your device and put safestrap on.

Hi, I was wondering if there is a way to install this Modem on my Canadian S4. Without it, turning off the screen when Running any 4.3 TW ROM will make the phone too loose signal. When using Odin, it fails and nothing get installed.
Thanks!

First, this question should be asked in either the Q&A section or the specific thread. Second, from what I read someone already tried and even posted in the thread and it didn't work.
Hello,
First off I am very new to this. I always try to be as careful as possible and do as much research as I can. I follow all the steps as directed and ask questions ahead of time before screwing things up.
My problem now is I accepted an OTA update to 4.3 from what I thought was a stock 4.2.2. Apparently I was wrong and the superUSER app was still installed on my phone. I no longer have the ability to use my WiFi- (I switch the toggle and it just stays off) I have tried to reset and restore. I have tried to delete all data and re-install. I have tried everything I'm comfortable with at this point. I dont know if I should try using ODIN to flash stock since I probably have a knox bootlocker and dont want to do more damage. I am posting photos because I noticed my naseband and my build number don't match up. I am afraid im stuck in between 4.2.2 and 4.3. I would greatly appreciate any advice or even a push in the right direction. I have been searching trying to find a solution for over a month and the most I can get is... "your an idiot, dont update OTA while rooted, etc etc" Hindsight is 20/20. Thank you again for your time.

I am not an expert but from what Im seeing your on a 4.3 rom but the modem did not update. Your modem is still mf9. I would flash a 4.2 rom and go from there. I don't want to give the wrong info hopefully someone can chime in that knows more than me.

Yeah that is what I was noticing as well. I have soft bricked my phone twice now trying to use odin and going back to a stock 4.2. The flash says fail everytime. I am wondering if KNOX is blocking ODIN from flashing the new ROM. Thanks for your quick response and I guess this means I am on the right path. Now I just need to find a way to flash a stock 4.2 on my fluster clucked half 4.2 half 4.3 phone.
I do know that once you're on MJA there's no going backwards. Try odining the modem. Make sure you turn your phone off...then boot to DL mode. Don't just boot to DL mode seems to work better that way.

I would suggest first trying to reinstall your mf9 modem via odin , if that doesn't work I'd try to install the mja modem via odin. You can find the links to files here http://forum.xda-developers.com/showpost.php?p=42954149&postcount=2
And a thread about a similar issue so you can get a better idea of what you need to do.

i root my gs4 with odin, everything went fine but I wanted to get my gs faster so i downloaded kernel for gs4 and flashed it. mistake here. i didnt check if it supports 4.4.4. it only support devices under 4.3 so.. no wifi. that was the problem i had other than that, all was good. than I downloaded some OTA file for my gs4 and when i tried to flash it with safestrap, it kept said fail. so i thought it's maybe because i already have OS installed... so i wiped system,data and i tried to flash that OTA file, fail again. now im screwd. there is no OS on my gs4. when i trun it on, it vibrates, than reboots and than goes into Odinmode and say something like "nornal boot not possible" in red.
so i spent couple days searching how to get my phone work again but everything i tried didnt work. and for galaxy s4 sgh i337 nj4 version 4.4.4 it even made me think it was made just for me.
i tried kies, failed it told me to do emergency recovery but my phone does not show on list.

You'll have to use the ODIN file from this thread: http://forum.xda-developers.com/showthread.php?t=2674223
Flash that in ODIN, use the rootable version if you want to root it using towelroot.
Besides that, you can't flash any custom kernels on the S4 unless you're on the 4.2.2 MDL bootloader, and there's no way to get back to that from 4.4.

I have a GT-i9505 that I've been running the stock Jellybean Touchwiz 4.2.2 ROM on since forever (I9505XXUAMDD). I recently discovered compatibility issues with some updated apps and decided to give the latest Touchwiz a spin. Since my phone is rooted i couldn't get the update via OTA so I downloaded the latest Touchwiz ROM (I9505XXUHOL2) and flashed it manually. It went well but I didn't really like it and I didn't have the time to set everything up again so I restored my original setup using a nandroid backup but now things are all wonky. I can't mount my SD card and wifi won't turn on. I suspect this is because the kernel is still the one from the 5.0.1 flash while the ROM is back to the 4.2.2 one. Under the about device menu the android version shows 4.2.2 and the build number is the original I9505XXUAMDD but the baseband version shows I9505XXUHOL2 and the kernel version shows 3.4.0-431985. In addition when booting up the phone it shows the "SEAndroid...kernel" message in the top left corner; not sure what this is.
Is there a way to remedy this or am I SOL and forced to use a later version of Android? Thanks in advance!
Edit: So further research suggests it's actually the Baseband version that is causing the problem so flashing the correct modem should fix it. Could someone please show me which modem is correct for I9505XXUAMDD? Also, will this fix the kernel message I keep getting? Thanks!
You can't downgrade from lollipop that easily
There's threads in general relating to downgrading
Could be a mismatch between the phone bootloader and baseband. What bootloader version and baseband is on the phone? If they match, it could just be that the bootloader and modem are too new for the rom.

Yeah, I realize that now. I put too much faith in the nandroid restore. I had tried out the JFLTE-GPE ROM once before and a nandroid restore reverted the device without issue so I just assumed it would do the same in this situation. I will look into the downgrade process.

I was under the impression that a nandroid restore would flash the bootloader as well but my faith in nandroid backups isn't what it used to be
Guess I'll have to look for the appropriate bootloader and modem for the ROM.
You can install the Samsung Phone Info app from the Play store to confirm your bootloader and modem.

Wifi is out so I don't have access to the play store
I used the terminal emulator to check the bootloader version and it's indeed still on I9505XXUHOL2. I've read somewhere that once a newer version of the knox bootloader has been installed, attempting to flash back to the 4.2.2 bootloader will brick the phone. Is this true?
Thanks again!
I don't know about the 9505 but you can't downgrade on the s3, i337, and note 2.
Personally, I would flash back to stock to make sure everything still works.

Will do. I'll pull up the I9505XXUAMDD from sammobile and give that flash when I get home this evening. Thanks again!
So I flashed to stock I9505XXUAMDD but the wifi and sd card issue remains and the bootloader still shows up as I9505XXUHOL2. Not sure how to proceed.
I'm starting to get the feeling that 4.2.2 is a lost cause...I guess downgrade on GT-i9505 is not possible.
Edit: Baseband version is now I9505XXUAMDD and wifi is still not working.
Update: Flashed to I9505XXUHOF2 and everything seems to be all peachy keen for now. Will update again once I restore all my apps and data.

No it's not. It's not possible because you cannot downgrade the bootloader.
Perhaps you can still go back with 4.2.2. custom rom but in my opinion it's really not worth it. It's not worth to stay on an outdated version with all the security vulnerabilities. I would recommend anyone to use CM because then you can run the latest software on your phone.

Thanks for confirming and thanks for your input :good:
I really did enjoy the Jellybean experience on the S4; going to Jellybean from ICS felt like an upgrade. I feel like that was the best match for the phone and it just went downhill from there (as far as the S4 is concerned). I suppose it's time to move on.
Update: All apps and data fully restored and it seems stable save for some small quirks. Not liking Lollipop though.
