Hello everyone-
New user for the Samsung Galaxy S4 here. I used to own both the iPhone 3GS and 4S prior. My general background was writing VB in version 3.0 for AOL back in the late 90s for all you old school people, progs/punters that may remember those days. Unfortunately, even now I'm still have issues following along with new technology. So far, I have really enjoyed the android system and have made modifications through various launchers. I did use SuperSU and rooted the phone by the automated process. I realize these may be 'noob' questions, however; everyone I suppose goes through it at some point. I do have some general questions and several of them that I have read about have conflicting information. This will be somewhat long, but I do appreciate any input:
The Galaxy S4 that I have is SPH-L720, MK2, and 4.3 version.
At this point, I backed-up and installed several Google Games, Books, and Sprint ID, Sprint Worldwide, etc.....general bloatware using Titanium Back-up. Again the root method I used was SuperSU by Chainfire. I have NOT use TWRP/Clockwork Mod or flashed any custom ROMs. I just have it rooted and diabled some bloatware, installed Xposed Installer and other root only apps. I checked my phone and its status says 'custom'.
1. Given this set-up, can I still get OTA for new Android versions ? I don't care if it removes root, but I was just wondering if I can get OTA updates to get new versions for my phone. Some threads I have read say yes, others say no. If I cannot, how can I then get new updates ? I don't want to not be able to permanently update to 4.4 in the future. I know there is a way to update via Kies to the computer.
2. The root access via Chainfire SuperSU involves 2 components from what I understand. SU.apk and busybox. I was using Terminal Emulator based on the advice from this thread: http://forum.xda-developers.com/showthread.php?t=2565758
I could not get it to work when typing in the prompts on the screen, it just would not go through. I tried downloading Total Commander which allows root access. Can I instead of using Terminal Emulator to get rid of busybox, use Total Commander to get into the /system/xbin folder and manually delete all busybox files prior to using the permanent unroot of SuperSU feature in settings ? Or does the Full unroot remove everything ?
3. Maybe I still don't understand the flashing process, but it seems, you download Odin, then use the ROM file you need under the PDA selection then start the process while the phone is in download mode (home button, down volume, etc...) Is this how all custom ROMs and re-stores are performed ? Is this form of the restore different that the phone Samsung settings (back-up/restore) ? I've read about TWRP, custom recovery, Clockwork Mod, etc....but I dont understand what all these are. It seems easy enough to download files then put them via Odin then hit start....
At this point, I've refrained from doing anything other than back-up/uninstalling some bloatware and using some cool apps that supposed xposed installer. I'm worried that I might brick my expensive phone or render it unable to get anymore updates :crying:
Thanks for the input !

I can answer 1 & 3 for you.
1. No, you won't be able to take an OTA because you removed or modified system files. This will cause the update file of the OTA to abort once it encounters the modded file or can't find the file your removed. The best process to take an OTA would be to return the phone to stock before taking the OTA. The easiest method is to use Odin and install the full stock tar file that you are currently on. In your case it would be the MK2 tar file. This will return your phone to stock with the stock recovery and allow your phone to update via OTA, then you can re root.
3. Odin is used to flash things like stock tar files, modems(basebands), recoveries & firmwares. If you are installing a custom rom, that is usually done using a custom recovery like Phillz's or TWRP. These recoveries can be installed via odin or TWRP via goomanager app in playstore. Once the custom recovery is installed you copy the rom file or other mod to your sdcard and install through recovery.

Thanks for the response....Does it matter what version of Odin I use if I were to restore the phone back to stock ? Also do I need to manually remove all rooted program and features, or can it be flashed back to stock ROM as is ? I have a lot of apps that I also don't want to lose and I've tried manually back up files on my SD card, but I didn't know if there was a way to back it up, so that it literally can be dumped right back in when stock is restored.

I believe if you are on MK2 you will want to use the latest version of odin which is ver3 3.09. If you are using the MK2 complete stock tar file it will rewrite everything in system and restore all the apps that were removed or modded so you don't need to manually remove root. Currently, the stock files available to us do not wipe the data partition so anything you have in that partition will remain there unless you do a factory reset. One thing you will want to make sure you are doing is backing up to the external sdcard and not the internal. You can then use TB to replace any files if you did a factory reset.

I'm using Kies 3 and using the data back-up feature ? I assume this is backing up to the computer then I was planning on using the 'restore data' feature once they phone is back to stock. Will this revert it back to the way it was previously customized before root ? So if I understand correctly, once I download Odin 3.0, I load the MK2 .tar file into the phone, enbable download mode, then hit start and the phone will be like it was out of the box and ready to be OTA and restored with prior data ? I may be confusing flashing the stock firmware with factory reset ?
I also noticed there is an update firmware feature on Kies 3, if I try using this while SuperSU is present and the phone is rooted, will I also have a failed update/issues ? Again, thanks for your help. Do appreciate it.

I have never used Kies and heard that it doesn't work with the MJA or MK2 software yet. I don't believe Kies will work if your status is custom but I could be wrong on that. If you odin the MK2 full tar file your phone will be back to stock but your data should still be there. You will only lose your data if you do a factory reset in recovery. Remember, a factory reset is just wiping the data partition and does not restore any software or apps.

Ok, I think I have the general idea. It sounds similar to putting back on the stock 'image' nothing else.........I currently have the Odin 3.0 software, but I have been having a hard time finding the stock firmware online and downloading it. I will keep looking. Once I get the .tar and flash in download mode, will I just see all the bloatware back on, but everything else the same ? I was wondering what will happen if I kept Titanium Back-up, SuperSU, and Xposed Installer on when I do this ? Does it just render them all un-useable, but the new OTA will still install anyway ? Thanks.

Every thing in the data partition(titanium backup) will remain and everything in the system partition (SuperSU & stuff modified via xposed installer) will be gone and replaced with the bloatware.

Ok, so it appears to have worked. I flashed the 4.3 prior version however it was hooked up to wifi and automatically downloaded the new version and removed root (not a big deal). My status says custom still, but I am assuming that I can OTA after the flash b/c it updated to the most recent 4.3 in Dec 2013. I re-rooted so it is back to prior, but I know now how to do it.
Is there anything that I may delete or uninstall that cannot be replaced by flashing the stock firmware ? For example I was thinking about getting rid of the 'help' on the phone and Titanium Back up said it is odexed or something to that extent and can only be replaced by using Titanium Backup and the exact same copy ?
I figured that I might as well just try deleting the bloatware and not back up b/c worse case scenario if something happens I can just flash back the stock ROM and all is well ?
Being able to flash the stock .tar through ODIN gives me peace of mind from screw ups, even if it removes root and takes time.

If you haven't spent much time customizing, that'll work fine. Most of us use custom recoveries (like Philz or TWRP) to make "nandroid" backups of our setups. A nandroid is like a drive image on a computer, so restoring it will restore all of the customizations you've done (accounts, apps, app data, bloatware deletions, etc). Nandroids don't back up firmware (modem, bootloader,etc), but back up the ROM completely. A Titanium backup is almost as good, but requires a bit more work.
As for deciding what apps you can delete, most of the custom ROM creators post a list of the bloatware they remove. So, if it's on their list, it's almost certainly ok to delete it on your phone too.

Thanks being able to flash the stock .tar and use ODIN gives me peace of mind of any potential screw ups. So far I'm just using stock rom and toggling some of the features with xposed installer and titanium back up.
I'd like to explore more eventually with custom ROMs and I've heard of Clockwork mod and TWRP, Nandroid, Cyanogen, etc... but I don't know what any of that means or what it is.
Is TWRP/Philz like ODIN program then you download custom ROMS like Cyanogen the same way as the stock firmware. tar ?
As you can tell I am extremely new to this.....this is also my first time owning an Android phone as well, but I never messed with jailbreaking my past 2 iPhones in the past. I just have used VB 3.0 back in the day....

To me, one of the hardest parts of this whole thing is getting to the point where the basic terms make sense. I've been at this for a couple of years with an HTC Evo and now the GS4 since October, and sometimes it still makes my head spin. Here is an attempt to explain my understanding of a few things:
1. Booting...you can boot into Download mode, recovery, or system. Download mode is what you use with ODIN, you need the correct drivers on your computer (which can be found lots of places), so that ODIN and your phone can communicate. In download mode, the phone just accepts whatever ODIN sends it, so it's the easiest way to totally brick your phone. Don't mess with partitions and follow the instructions for whatever you're doing very carefully, because I think this is the only way to "hard brick" your phone.
2. Recovery - something you use to create images of your phone's ROM (nandroids), flash ROMs and mods, and restore past nandroids. The stock recovery will only flash approved updates from the carrier, so to do any of the things I listed you need a custom recovery. Most people use Philz (which is based on the ClockworkMod recovery) or TWRP. To flash the custom recovery, use ODIN and follow the instructions in the thread exactly. There is a way to flash recoveries without ODIN, but I've never done it. I was using TWRP, and switched to Philz to flash the rooted stock 4.3 update because the thread suggested it. They both seem to do the same thing, and I have been happy with both. I'm sure there are technical differences, but I couldn't explain what they are. You can switch back and forth as much as you'd like between the recoveries with ODIN. Recoveries can flash a complete ROM or just partial changes (like the hotspot mod). In a custom recovery (or the stock) you can also do factory resets and cache cleaning (most ROMs suggest you do this before flashing). Factory reset doesn't return the ROM to the factory original, it just clears out all of the user data (including user apps). A nandroid is the fastest way to restore a phone if you screw it up...I always make one before making significant changes to the phone. It takes several minutes to do, but I think it's well worth it. The operating system can't be running when you make one, that's why you need to boot into recovery mode. You create a Nandroid in Philz by selecting "backup and restore" then "backup to" which will allow backup to the internal storage or external SD card.
3. ROM - the actual operating system used by the phone when you actually use it as a smartphone. There are 2 basic flavors for the GS4...touchwiz and AOSP (Android Open Source Project). Touchwiz is Samsung's "flavor" of Android, AOSP is the "pure Google" version of Android. A lot of the things the GS4 will do rely on touchwiz (multiwindow is one example...but there are several). Some people really like the AOSP ROMs (Cyanogen is AOSP), but make sure you understand their limitations. I've never used one on the GS4. There are several touchwiz custom ROMs which have various features. I've tried a few and just settled on the stock rooted touchwiz ROM, but there are lots of options from great developers. I think most custom ROMs require you to use a custom recovery to flash them, but there might be ways to do it using ODIN. I like having a custom recovery, so I've only used ODIN for flashing modems and recoveries.
4. Firmware - as far as I can tell, there are two important parts of the firmware...the modem (sometimes called "radios" or "baseband"...find your version by looking in "about device"->"Baseband version"...the different modems are described by the last 3 letters you see) and the bootloader. The modem and the version of the ROM you flash need to match or you'll have problems with the radios in the phone (wifi seems to be the biggest problem if you have a mismatch). MF9 was the last modem version based on 4.2.2, and 4.3 has had MJA and MK2 (MK2 is the latest). The bootloader is what the phone uses to initially decide how to boot up. If you have the 4.3 version of the bootloader it will include "Knox", which will prevent you from flashing older versions of the modem, so you'll have to use a 4.3 ROM. Knox also "trips" a counter if you flash a custom ROM and Samsung claims they won't honor the warranty on a phone with the "Knox flag" tripped. If you have the 4.3 bootloader you're stuck with it (for now at least). I still have the 4.2.2 bootloader, so I don't have much more to offer on this subject. There are ways to get the 4.3 modem and ROM without the 4.3 bootloader. There is a lot here (and lots on youtube) on how to navigate the Knox minefield if you care about it. If you still have the 4.2.2 bootloader you can flash older (and newer) modems as much as you'd like without getting the updated bootloader using ODIN.
Hopefully this helps...this is a great place with lots of great people. Sometimes the scale of the amount of information here is overwhelming. But, search is your friend along with lots of time! Feel free to keep asking questions.
thanks for explaining this nobody-
The information does help quite a bit and I am still learning, however; I do enjoy the process of messing with the phone. My GS4 now runs the RAM at 750-800mg instead of a bloated 1.2GB which was happening quite a bit. I had to originally not use a lot of apps I wanted to like Facebook bc the programs themselves bloated up to accomidate the existing bloatware which was also running. I did flash my phone back with the stock firmware today and it looks like it installed all the stock software. My status said 'custom' when I looked at it however I was already connected to wifi and it went from 4.3 (Oct 2013 version which I flashed) to Dec 2013 version automatically so it appears that the OTA feature works.
I assumed if I accidently delete something from the phone that I really need to affects the phone, I can always flash the stock ROM to fix it. Losing the root is not that big of an issue, but I did lose Superuser and had to re-root the phone. I suppose I do have a few more questions, one was when I was reading another carrier provider thread.
1. Is there anything I can delete from the phone that I could not eventually recover by flashing the stock firmware ? When I uninstall for example the 'help' app on the phone Titanium Backup says this only copy can be replaced by using Titanium 5.1 and it's existing copy ? Could this just be replaced by flashing the stock firmware as well ? I like being able to flash the stockfirm ware rom at any point as a fail safe.
2. The other issue is the bootloader that I heard about ? It was on a Verizon thread where the person was able to flash the stock firmware on his phone, but then after an upgrade, he was not longer able to flash the rom b/c the carrier in the most recent upgrade he did blocked ODIN ? Is this something that I should possibly be concerned about in the future not being able to flash stock firmware via ODIN ? As you can tell, I'm pretty OCD about being able to have a failsafe for my phone. LOL. Thanks again for your help, I do appreciate it.

Yes, you can always flash the stock firmware to fix whatever you do to the ROM (just to the ROM, use ODIN very carefully). In the case of the Help file, you could also back it up using Titanium, then delete the app, and restore it later using Titanium if you want it back. This is probably obvious, but use Titanium to delete the app, but don't delete the backup.

Sprint is a lot more friendly toward its users modifying their phones than Verizon. But, they could change their minds any time. For now, there are no issues (other than the Knox warranty issue). But, don't presume that'll always be the case. The best precaution is to not take OTA (over the air) updates. OTAs are the ones that pop up as a notification on the phone saying "system update available, tap to install". Kit Kat should become available in the next month or two, who knows what'll come along with the OTA. Threads will start here almost immediately when the update rolls out; watch those threads and don't do the update until you're comfortable with what's inside. I will wait and flash something from the development section, even if it is just the stock ROM.

It was good that you mentioned the Knox bootloader issue with the 4.3 upgrade. When I purchased my cell phone back in Nov, I believe it had the 4.3 (1st) version loaded, but it already had Knox features as I do recall seeing them. If I were to try and flash 4.2.2 like the version you initially had, would the phone have a bootloop error or fail to flash because there were some free wifi tethering exploits that were not yet fixed in the 4.2.2 version ? This may have been the error I read about due to the new Knox feature.
I think since my phone is currently rooted and I altered some of the bloatware system files that the update if it were made available OTA should not update anyway due to the root. Will the stock ROM/firmware .tar files eventually be posted in the developers section that can just be flashed via ODIN later on ? With that, if I were to load 4.4 and not like it, could I flash back 4.3 ? I am guessing this is the part where you mentioned that the carrier may decide differently later on.....I suppose I will just keep an eye out in the meantime.
Good good............, I'm picking up this pretty well so far.............

I'm not sure what symptoms you'd see if you installed 4.2.2 with the 4.3 bootloader. Most likely the phone would fail to boot. ODIN will flash whatever you tell it to, I don't believe it does any compatibility checking on its own. You can still get the wifi hotspot feature to work even with Knox and the 4.3 bootloader, I don't think that was what they were trying to do with the update. There are threads discussing 4.3 and what changed, but there wasn't much obvious to the user. For now you can't go back if you're on 4.3, but there might be an exploit discovered down the road that lets you get the old bootloader and go back.

Yes, they won't be available immediately though. It can take some time for the community to re-obtain root too, depending on how big the changes are.
With that, if I were to load 4.4 and not like it, could I flash back 4.3 ?

I think you alluded to the answer already, but it depends. It took a month or two before you could flash the stock 4.3 without the 4.3 bootloader. There were custom ROMs available that used custom kernels sooner, but there was a problem trying to use the stock kernel with the 4.2.2 bootloader. So, always read and read and read some more before flashing updates.
So far i think i got the hang of it. I have been modifying the phones original touchwhiz. I ended up freezing alot of files instead of deleting them so the ability to turn them back on is there. Some of the files while there are not meant to be frozen/disabled/turned off. I tried a few methods for keeping SuperSU over an ODIN with no luck. I do have a question though. If i turned off (but did not delete) alot of system files and were to run ODIN again will all of them including the bloatware be turned back on and restored? That would be bad if i flashed, lost root, then simultaneously had all the system files disabled with no way to turn them back on......
This also a dumb question but what exactly am i flashing with ODIN? Its a 1.5 GB file with Sprint and it is a tar that restores all bloatware and turns the phone status back to official so i can get OTA updates. Am i flashing the entire stock ROM or just the firmware? Its nice that i have not lost any existing apps or data. It just restores the bloatware and removes root
Reading the above posts im guessing firmware....along the lines of the previous question will this restore system files and apps as well that have been shut off because ive been on a roll disabling and freezing a lot of files and apps and not sure what to turn back on to restore function to some of them. If the ODIN firmware flash resets all settings then that will also be very useful as well. Thanks much

The .tar you are flashing from sprint is what we would call stock firmware image. This is the image that shipped on the phone from the factory. I'm an avid flasher and would highly recommend installing twrp or philz touch, creating a nandroid backup and giving some debloated touchwiz roms a shot. You'll see some significant improvement in battery life and performance and some really cool upstream features. I use odin as a last resort, when I need to go back to stock for whatever reason (ie domestic sim unlock) or have fubar'd my current setup past a point of no return.
Okay, I wasn't sure where would be the best place to port this, so excuse me if I'm in the wrong place:
So, I was thinking about rooting my phone (S4 Verizon) and flashing the Cyanogen Mod 11 on it. I was wondering a few things about it though before I decide to do it...
1. Is there any way that I can flash the ROM, and still have my phone the EXACT way it is now, except with CM11? When I watch installation videos on YouTube, it seems like it refreshes your phone to simply having the stock Google experience, which I don't want. I'm currently using Nova, which I love, and I just really want... A. TouchWiz off my phone B. The Notification center of CM11 and C. The status bar. So, if there was any way to flash the mod and keep everything the way it is, similar to how you jailbreak iOS, that'd be great.
2. Is there any way to UNROOT the phone, if I ever need to? I have insurance on my phone with my carrier, so if it ever suffers a cracked screen or the like, I can get a free replacement, and I'm sure if I were rooted that'd probably be voided.
3. I was planning on picking up a Gear 2 Neo tomorrow. If I'm rooted and running a custom ROM, will I still be able to use the Gear to its full extent (as in, not like a G2 connected to it) while running the custom ROM? Or will the Gear detect that the device no longer has TouchWiz/has been modified?
4. Also, if it isn't possible to load CM11 like you would jailbreak, and you always start with a clean boot, how would I go about reloading all my data/ contacts/photos/apps/Nova setup? How/what should I use to back everything up?
Thanks a ton in advance, I know, I'm a noob lol
1. Mostly , but there will be slightly difference maybe, depends how you look things. I don't really get your point B and C.
2. Unroot yes, but you must know there is something called KNOX, which will avoid your warranty, and by now this can NOT be undone.
Which means, unroot is easy, but if your carrier checks KNOX, you are so dead...
3. I think, gear support is part of TW framework, which means CM11 will be act like any other non-samsung connected to it.
4. I don't really understand it
If you mean the content in your internal/external sdcard, flash ROM will not delete them as long as you don't choose to (like option of format sdcard in recovery ) but you are on Verizon s4 , I don't really know about it, if it requires unlock bootloader, then you better back up sdcard first.
And yes, clean flash requires you to do apps backup and wipe data / cache / system before flash
Hi all,
It's been a few yrs since I've flashed a phone (the last being my SGS1 variant) and I'm very out of practice. That being said, I just need a little help in understanding how to flash my SGS4. So far, I've had this phone for yrs and I would've jumped to custom roms as I did normally but there was the whole KNOX debacle and I didn't want to do anything to damage my phone - while within warranty. I've been out of the loop for awhile, so I need a little help in my choices here.
My phone is still running on it's original software (that's right, I completely haven't updated in yrs), so it's a 4.2.2 and the build is I9505XXUBM4 (pre-KNOX). If I am going to root, I was thinking that I should use the method from this thread: [GT-I9505 + GT-I9505G] CF-Auto-Root. Would I be right in using this method or is there something better?
Secondly, I've only ever used CWM. I'm assuming the recovery to use currently is TWRP since I've seen it brought up in a good number of threads. Can I make a nandroid with TWRP the same way it was done with CWM or do I need to find another way to backup my data?
Lastly, this is the rom I'm leaning towards; [JDCTeam][6.0.1][9 July] The Android Open Source Project MOB30M. Could I just flash this on top of my stock or do I have to update first and then flash this?
TIA for your responses.

For first you MUST update your phone, if you have root, update with odin on the latest firmware version and then flash flash recovery(cwm, twrp, philz) and flash the rom, because firmware request of the rom is android lollipop stock. Try cyanogenmod 13 nighty for this smartphone

Ok, so after I root the phone, can I go straight onto CM13 or do I still have to get lollipop first and then flash CM?
I'm still trying to avoid getting KNOX on the phone.

Knox does matter once you're on a custom ROM.
Most content creators recommend to use the latest modem and bootloader in order to avoid problems.
You don't necessarily have to update the whole ROM to have the newest modem and bootloader, there are Odin flashable packages.
I don't know if CF-Auto-Root works with 4.2. I know it works for 4.4 and above.
As long as you do your wipes (this means system, data, cache, dalvik) you can flash anything over anything.
Yes, you can do nandroid backups, but TWRP and CWM backups are not compatible with each other. Also, TWRP has a problem with TouchWiz backups, meaning you can make and restore a TouchWiz backup, but it either won't boot or will give you lots of errors.

Ok, so is there a way that I could at least get to lollipop w/o getting KNOX and have a nandroid that would work or should I just OTA all the way up to current and then root and flash?

Why are you so obsessed with Knox? I just told you that it won't be an issue on custom ROMs. There is no knox on custom ROMs. Knox is a Samsung thing. So, unless you plan on staying stock, there is no reason to be concerned about it. Even if you stay stock, there still is no reason to be afraid of it, it's just some security crap, and it won't affect you in any way. Why are you so afraid of it?
My device came with Knox pre-installed and it didn't do jack.
Just update if you want to update or flash a recovery (flashing custom ROMs doesn't require root, just a custom recovery) and flash your desired ROM.

Well, I've been out of the loop for a while (the last time I was active was circa late 2013/ early 2014), but I do remember there was a lot of concern regarding warranty and the flags. I do admit that there was a lot of speculation from losing a section of memory from tripping the flag to actually burning the motherboard. I originally decided to wait until the dust settled but life took over and I ended up only sporadically checking the forums before disappearing for long periods of time. I actually don't know what the end of the story is to be honest.

The only concern is about the warranty. Since your phone is some years old, I doubt that is an issue for you anymore.
By losing memory you mean losing data or actually losing storage space?
Either way, I haven't heard of anyone with such a problem around here.
Nor about somebody with a fried motherboard.
There might have been some unfortunate cases, but this is to be expected when you modify your device. There always is a risk of damage, it doesn't matter if it's by rooting or by flashing a ROM.
I meant lose storage. As I understood it, KNOX worked like a container and once the flag was tripped, you'd lose whatever it contained - as in never being able to access that bit ever again.

You have to use the knox app first for that to even be considered a risk.
Knox will not put anything in that container without user input.

Ok, so to get the steps straight:
1. I'd need to get a lollipop bootloader & modem
2. root + nandroid (CWM) + titanium for app data (non-system app data)
3. change recovery to TWRP
4. flash rom + gapps
....and then I should be ready to go, correct?

1) Is not mandatory, it's just recommended. The only exception is if your device is a Verizon or AT&T phone, then don't - and I repeat - don't update or you risk losing the possibility of any custom ROM flashing or rooting due to the locked bootloaders.
2) and 3) CWM and TWRP backups do not have cross-compatibility. If you backup with CWM you have to restore with CWM.
Please tell me you haven't flashed anything yet. I can help with the entirety of the procedure.

No I haven't done anything yet. I found something else to occupy me for the last few nights - a chromecast that seems to hate me.

Haha I hear ya. I've been building a kernel for about a year now and finally (knock on wood) arrived at something I'm happy with. Lesson learned, electronics are definitely conspiring against us.
That said, please feel free to pm me when you're ready for the flashing process. Though it's a silly skill, it's become second nature to me and something about your situation flipped a helpful switch in me : P what's the Chromecast like?

Well, so far, the chromecast is only plugged into my tv and basically did the setup by itself only for the google cast app on my phone to not recognize it when it said that it's ready to cast. I've ran out of things to do aside from going to the google forums (which I've already done). I'm starting to wonder if it's my phone that's causing all the issues.
Hello,
A few months ago, I was able to successfully root my AT&T S4 (SGH-I337, builld LRX22C.I337UCSGOK3) using KingRoot. The KNOX warranty bit was not set at the conclusion of the root process.
After wrestling with storage problems, including the "system memory" taking up 6.29 GB out of the meager 16 GB that is on this phone (preventing practically any Google Play updates from occurring, as the available space would always dip below 500 MB periodically), as well as performance problems (very long delays for some touch events and a general resentment of TouchWiz), I decided that enough was enough, and I decided to change my ROM/OS out for LineageOS.
LineageOS offers builds for jfltexx, which is reported to work for jflteatt since they are similar enough. I am not really willing to try "older" builds, as one of my goals is also to bring the security of the operating system up to date, so I am not exactly inclined to go for old CyanogenMod builds. The LineageOS install guide stipulates that I install TWRP to successfully install the OS via a supported recovery; however, the message SECURE MAGICCODE FAIL: recovery appears, as the upgrade process seems to be expecting something signed by Samsung (right?). Other guides warn that the stock recovery only allows stock OS installation and not custom operating systems, so I decided not to try that route. This effectively prevents me from installing LineageOS due to a problem that is inherent in OK3.
Why did I make the mistake to install OK3? More than a year ago, I decided to do the final update that AT&T pushed out for this phone. Thinking that it would be something significant, I went for it, only to find out months later that it was a minor update whose purpose was also to add an additional lock to the bootloader. As this phone is "fairly old" (is 2013 already considered ancient times?), I have not found many guides that cover OK3, and those that do pertain to either rooting the S4 (already done) or something about downgrading (but I can't really do that, seemingly due to the OK3 lock-in). Oops.
That said, is there any hope to bring more life out of my phone, or is it time to throw the phone out and buy a Pixel or related product like any typical consumerist would do? My goal is to move to another OS to end the storage problems and other quirks of this phone that I have grown to deplore; that is all I wish to attain.
The phone is relatively reliable: it had ~1200 hours of uptime before I had to reboot it a few days ago to fix a data connectivity problem. The battery is also very manageable and can last a day and a half in regular use, but it can last 2-3 days under maximum power-saving mode.
I have read the rules and done some research on this forum, among some others. Thank you for your assistance.
Upgrading the phone to 4.3 locked the boot loader which prevents the installation of TWRP.

Yes, anything past MDL has the bootloader flaw patched. MDL firmware and below have a flaw in the bootloader that allows loki doki to be installed bypassing the bootloader lock so you can install TWRP recovery and custom AOSP ROMs.
Since you're on OK3, you're forced to use safe strap recovery and can only install custom touchwiz ROMs like golden eye and albe95.
If you want to read up on the MDL bootloader, I have written a guide here: https://forum.xda-developers.com/galaxy-s4-att/general/how-to-one-guide-to-mdl-bootloader-t3584122
My wish is to escape TouchWiz, so I suppose I have hit a dead end.
Thank you for your help anyway.

If you want away from touch wiz, I think there's a Google play edition ROM for the galaxy s4 that you can use with OK3, but I am not too sure. I would just check the galaxy s4 ROM section for it. I'm on the MDL bootloader which allows me to use TWRP, so I don't know too much about safe strap recovery.
Even if one wanted to do a TouchWiz-based ROM, I don't think we on OK2/OK3 even have the option to install SafeStrap, so far as I can gather
Hold the phone, I think I've found something. Evidently we can Odin back down to NB1 and go from there! Experiments, here we come.
Yes, NB1 is as far back you can go I believe without bricking your phone.
