[Q]Downgrade from Lollipop to KitKat (ATT Galaxy S4 SGH-I337) - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have an ATT Galaxy S4 (no longer under contract) that is now running on StraightTalk. I did the upgrade from KitKat 4.4.4 (I337UCUFNJ4) to Lollipop 5.0.1 ( I337UCUGOC3). I really do not like the update and hopefully you all can help me out. I’ve been reading online about using the Odin software to flash back to a previous version. Can the flashback to KitKat be done without any ‘rooting’ as I'm not into that just yet? At this point but simply want the easiest way to return to KitKat 4.4.4. Is the process fairly simple and what are the steps and how can I get access to the I337UCUFNJ4 software? Thanks.

@ThinkWolfpack

[Q] Can I upgrade to 4.4?

So when I first got my note I imediately used this guide to flash kitkat and completely ****ed it up, it just stuck on the Samsung n9005 screen.
This was a link to C4ETech's video called "Galaxy Note 3 - Samsung Official Kitkat 4.4.2 - How to Flash/Install" but I had to remove it.
I assumed it was something to do with the CSC code (mine being BTU) so I installed a BTU rom using this guide.
This was a link to TheSmokingAndroid's video called "HOW TO UNBRICK & UNROOT SAMSUNG GALAXY NOTE 3" but I had to remove it.
Now I want to install a kitkat rom preferably a stock one but there isn't one for BTU. So I looked at the custom roms as some support BTU but require the device to be on 4.4 already. How can I get onto 4.4 if every 4.4 rom requires a 4.4 phone? Will I have to wait until an official BTU update comes out?
I've attached a screenshot of my About Phone page (which doesn't have BTU anywhere, I don't get it).
I probably have the complete wrong end of the stick so sorry for wasting everyone's time but if you have a minute to help I'd really appreciate it.

Try *#1234# might come up there. Anyways, go over to Sammobile and grab any of the latest 4.4.2 KitKat ROMs for your device (9005) as you said. And it should work fine.
Advice: Wipe your phone, not compulsory but advisable. Cheers!
I have a canadian variant note 3 900w8 and i want to flash 4.4.2 as well but i was hoping to flash the t-mobile version as i have heard of issues with the 9005 rom compatibility, just wondering if anyone has had experience yet, or if it has been done.

Thanks for your help but I've already done that and the newest version I can get is 4.3 I'll just wait until my phone gets the update, Thanks anyway
I've managed to get onto 4.4 now by flashing a polish ROM after reading that they support BTU, I don't know how to delete this thread so I'm just letting everyone know my issue is resolved

If you want the ability to flash back to 4.3 from 4.4, install custom recovery and roms and keep your Knox 0x0, head over here and do some reading ( if you haven't been there already ).

@Claudio21CH
1 Download the firmware from sammobile.cpm
2 Pc ODin you must have used it fpr rooting.
Flash the firmware with pc odin to your phone via usb cable.
Same procesure you have used to root your phone.
Sent from Galaxy Note 3 SM-N9005
thank you very much, will try and keep you posted!!
I visited sammobile and checked their firmware section. Seems for my build (N9005XXUMBI6) there is NO firmware update to 4.4.2, only for 4.3. My phone was bought in Switzerland without carrier lock. Can I just use one of the firmware where it says 'country unknown' or do I risk to brick my device? Thank you once again

What is your CSC?
Use this app Phone INFO ★Samsung★ to see what is your CSC.
Also in this app. you can enter the Menu --> select 'Firmware Browser...' to see a list of available stock firmwares for your phone, including the latest one.
Thank you very much

Nope, it is CSC version, not the actual CSC code.
I mean the 'Active CSC code' in the CSC INFO section.
Anyway you can enter the menu and select 'Firmware Browser' to check for the latest firmware by yourself.
________________________________________________________________________________________________
EDIT: Ok, AUT is Switzerland and the latest firmware is N9005XXUENB4 on March 2014, Android 4.4.2
The download link for this firmware is also given in this app.

What is your KNOX state, If its still 0x0, the you would need the mobile odin pro 4.0 method to update to keep knox 0x0.
Thank you all. Finally managed to upgrade to 4.4.2 with firmware from sammobile.com but now realized that I don't have root anymore. Will use CF autoroot for 4.4.2.
Cheers

Use odin program. Download files from sammobile. Com
Download for your version.
Read some more ^^
what is best way to ensure correct version
Bootloader is N9005XXUGNI4
Baseband is N9005XXUGNL1
PDA is N9005XXUGNI4
CSC N9005OLBGNL1
it says 4.4.2 is current however everyone else I know has 5.0 Lollipop
how can I update this to lollipop
better dont
You should wait a bit more and stick to the kit kat since lollipop is not polished an fixed entirely for average use. Don't get me wrong but if you don't know how to do it better don't do it yet because it can provide problematic install and/or bootloop. Even Samsung official update is stopped because of lollipop problems.
Cheers!
When you search for sm-n9005 in sammobile firmware section, download open German lollipop (not carrier ones). When you download firmware, there you can see how to install as the instructions are there. Gl

[Q] What model (version) of s4 is exactly this?

What model (version) of s4 is exactly this phone? which software is installed on it? is it stock or not ? plzz help and tell me its complete version details
My phone is sgh-i337 or gt-i9505 ? Or only baseband version is i337...or any firmware version difference ? Help
Open the back and remove the battery. Look on the label. Unless the person who sold you the phone physically changed the label, or removed it, it will accurately tell you the hardware version of your phone.
Given that the boot loader and modem (baseband) are for the AT&T version, SGH-I337, it seems likely that the hardware is I337.
Edit: Also, check that it's not a cheap fake clone. There are apps that can check hardware, and run benchmarks, etc. Search "Genuine Galaxy" on the play store.

I've really no clue. I'm not aware whether an AT&T modem will even work on that phone.
If the hardware is genuine GT-I9505, then you will most likely get a more definitive answer in the XDA-Developers forum for that phone.

It's most likely an I337 with an I9505 system. Either way, since the bootloader is i337, that means it's locked so if it ever was an I9505 it's not now, but mist likely it wasn't ever.
I checked indownload mode its sgh i337....can I install back stock firmware ...see this site http://www.att.com/esupport/softwareUpdateArticle.jsp?sid=KB419415&cv=820
is it possible to flash through odin this stock lollipop firmware?
Finally I got it....its i337...I checked imei on imei.info it says it is i337 and also checked for blacklist its all clean....and I opened back cover and see it and its written "MADE BY SAMAUNG" ...spelling of samsung is wrong ...it means sticker and software are of 9505 and hardware are i337 at & t usa carrier....I think its changed in korea...phone is converted....now planning to download stock firmware of i337 lollipop and install through odin...
if anyone have link plz share

The boot loader is locked, so you can't do this exactly. You can install stock KitKat, install safestrap, and upgrade to lollipop that way. You need to read through the forums to understand what you are doing before you proceed. I'd suggest you do quite a bit of reading, and only flash when you are sure you know what you want to do.

You seem to understand what you are doing. You should be able to figure this out on your own.
Start here.
Also this.
And this.
Or try some of the fine custom firmware in the Android Development forum.

I do not own this phone, so I can't test or speak from personal experience. I already gave you the links to the information you need ^^^. I don't know if you can receive Over The Air (OTA) firmware updates. You may not be able to if you're not in USA. Also, I'm not sure if you need to be on an AT&T sim. If you can, you can get stock lollipop without root with this method: go to the "[GUIDE]Odin to Stock, Updating, Rooting, and Installing Safestrap" which is the second link. Go to the second post titled "Odin to Stock, Updating, Rooting, and Safestrap Instructions" and click the button to expand the instructions for "OPTION 1 - Stock Lollipop (No ROOT)"
If you cannot receive OTA updates, then currently your option would be to first flash NB1, manually flash the NJ4 update, root and install safestrap. In the Odin to Stock guide, perform both step 1 and step 2 under "NJ4 -- KitKat 4.4.4" After this, you can use the "[How-To] Update to I337_OC3 - 5.0.1 and KeepRoot (4/7/2015) " thread, which is the third link above ^^^.
Your third option would be to wait until the developers post a method for flashing Lollipop directly from Odin.

I successfuly updated to 4.4.2 stock NB1 software manually thorough odin then manually flashed NJ4 by stock recovery...now im not receiving ota update to lolipop....now what nxt to do ? should i root NJ4 and install OC3...
And actually I dont want to root i nedd unrooted stock OC3 ...if you know any direct method to flash..
After update to nj4 4.4.4 im getting delays in sending text msgs and making calls....what to do now should i flash different modem or baseband any ideas ?? :/
Now that you have updated your user account, we can see that you are in Faisalabad, Pakistan using Mobilink carrier. As far as I know, you will not be able to receive an over the air update, nor be able to use Kies to update. Someone who knows more could give a definitive answer on this.
Assuming that you will be unable to use OTA or Kies, your options are:
- root, install safestrap, install rooted OC3
- wait unitl (and if) developers post an Odin flashable version of stock unrooted OC3.
As far as your other issues, you could install the NB1 modem (baseband) and see if that clears up the issues, as it was working before.

I downgraded modem to NB1 and no signal then i used OC3 modem it works bit better than previous one.....lags sometimes ...is there any way to flash 9505 modem to i337 phone ? :/
I upgraded to 5.0.1 using keeproot method of flashfire...thanks broo very very much.....
baseband problem still exists on OC3 modem....i maximum get 3/5 signal bars....can i flash i9505 modem using mobile odin or ant method ?
EDIT: i flashed successfuly 9505 modem but baseband version goes unknown and no sim/signal....is there any fix? Flashing efs?
What if I dwld 9505 lolipop from sammobile and install by odin or flashfire?

Can I downgrade my S5 from Lollipop 5.1.1 to Kitkat?

So I had to finally use my warranty for my S5 with Tmobile. I have the replacement but it came with Lollipop 5.1.1 and not Kitkat. I've started using Lollipop and it's a nightmare. I absolutely hate it and many of my apps are incompatible. I am a bit new to this but am well aware Samsung has pretty lousy performance with S5 and lollipop.
Knowing this, is there an efficient and safe way to downgrade without tripping knox? I did some googling but find more information on 5.0 Lollipop than 5.1.1. I'm surprised S5's got that update.
you can with no problem ( right now no one have problem with imei )

Thanks for the reply. What is the best way to get started reading up on that? I am a bit new to the rooting scene etc. I don't want anyone to spoonfeed me an answer--just kind of a general "where can I get started" thing so I can understand what firmware I need etc.
1. Go to sammobile website and click Firmware button.
2. Enter your device model in the search box
3. Select your country and the android version you want (in your case select 4.4.2)
4. Click Download button to download the firmware (you need to register to be able to download, don't worry it's free).
5. Download Odin and use it to flash the firmware you've downloaded (Google how to use it if you don't know how).
By the way, your phone doesn't need to be rooted to do all this. In the contrary, if it is already rooted, it will lose the root after doing these steps.
Hope that helps
