Download Mode
Download Mode is also known as Odin Mode on the XDA Wiki. The Galaxy S4 Active features the Android Download Mode which is a sub-system of your device that can be used to flash stock firmware files or any other type of customization file. Download Mode for Samsung devices allows you to install new OTA Updates by pushing them from your computer directly to your phone using only a data cable. Also, for your computer to work with the Download Mode you will need to have the Odin software present.
To enter Download Mode, make sure the phone is fully powered down, pull the battery if you’re not sure.
With the phone powered off, press and hold Volume Down + Home + Power.
Continue holding all three buttons until you see the Galaxy S4 Active Boot splash screen. Once the splash screen appears, released all three buttons.

Odin
From AndroidCentral:
Odin is software that was first leaked back a couple years ago from Samsung. Samsung uses or used it to "flash" or "install" firmware/os/kernels/radio's onto the devices. Samsung still uses it or a form of it in certain releases as a Window's Upgrade Tool as its been known. Its still basically old Odin underneath a custom Window's UI skin. Odin is your friend, respect it. If used improperly it can brick a device since it has the ability to flash very vulnerable sections of your device.

IMPORTANT: Odin is a very powerful program that can make significant changes to your firmware and bootloader. When Odin is flashing files to your phone, do not unplug the usb cord, turn off your computer, or interrupt the process. You could permanently brick your phone making it completely unusable.
As posted by @O-T, you cannot have Kies installed in order for Odin to work properly. If you are having issues with Odin, make sure Kies is not installed.
Unfortunately there isn’t a central location for downloading Odin. The Odin Program can be downloaded from several locations on the internet, so be careful where you get it from an make sure you trust the site you’re downloading it from. There are also several different versions of Odin: v1.83, v1.85, v3.04, v3.06, v3.07, & v3.09. Most Samsung S4 Active users have had success using v3.07, which consequently comes bundled with some of the firmware downloads. If you are having trouble flashing files with v3.07, try using v3.09 or v3.04, users have reported having success when using other versions of Odin.
For any update process, make sure to back up anything you don’t want to lose to an external SD card or source. Many of the updates will completely wipe the phone taking your back to the way the phone was when it came out of the box. Once everything has been backed up, remove the SD card and SIM card from your phone and follow the steps below.
IMPORTANT: If your phone has 4.3 or 4.4.2 firmware on it, then there is no way to downgrade to 4.2.2 firmware. If your phone has 4.4.2 firmware on it, it is still possible to downgrade to 4.3, but many users have reported bugs after downgrading.

Turn off your phone and reboot into the phone’s stock recovery. For more information on how to enter the phone’s stock recovery, please read the recovery mode section in the first post.
Once in stock recovery use the volume buttons to scroll to “apply update from external storage” and press the power button to select.

You may use other usb cables, but Odin may not detect your phone. If Odin does not detect your phone try connecting to a different usb port or a different computer.
If your phone has connected properly it should show up properly in the Odin window similar to the following picture:
Once Odin has detected your phone, hit Start. It will take a long time to flash the package to your phone and will completely wipe your phone. DO NOT DISCONNECT THE CABLE OR TURN OFF YOUR COMPUTER. If the process is abruptly interrupted you risk permanently bricking your phone, so be careful.
When the program has finished it is safe to disconnect everything and reboot your phone. Your phone will be completely stock, unrooted and you will have to setup your phone from scratch again. If you wish to root the ML2 firmware, please visit the towelroot website.

NH3 to NC9 (Official: Released 2014-04-16)
In order to return to stock, unrooted NC9 firmware, you must first be on stock, unrooted/unmodified ML2 firmware. For instructions on how to update to ML2, please see above. IMPORTANT: If you have rooted ML2 or modified ML2 system files in any way you cannot update to NC9 without wiping and reflashing the ML2 firmware. If you have rooted ML2 you cannot simply unroot, you must wipe and reflash the stock ML2 firmware.
Once you are on unmodified ML2 firmware, download the NC9 OTA File from the i537 Firmware Thread.
The file you download should be named 2400258.cfg. You will need to rename this from “2400258.cfg” to “update.zip” This is an important step because the file must be named “update.zip” in order for it to be flashed through stock recovery.
Place the update.zip file on your phone’s internal storage. Updating the phone to NC9 will be done without a computer so the file must be on the phone itself.
Turn off your phne and reboot into the phone’s stock recovery. For more information on how to enter the phone’s stock recovery, please read the recovery mode section in the first post.
Once in stock recovery use the volume buttons to scroll to “apply update from external storage” and press the power button to select.
Select the update.zip file that you put on your phone to begin installing the update. This process will not wipe your phone and should save all your settings and data from ML2.
Once it has completed you will be on stock, unrooted NC9. If you wish to root the NC9 firmware, please visit the towelroot website.

For any update process, make sure to back up anything you don’t want to lose to an external SD card or source. Many of the updates will completely wipe the phone taking your back to the way the phone was when it came out of the box. Once everything has been backed up, remove the SD card and SIM card from your phone and follow the steps below.
IMPORTANT: If your phone has 4.3 or 4.4.2 firmware on it, then there is no way to downgrade to 4.2.2 firmware. If your phone has 4.4.2 firmware on it, it is still possible to downgrade to 4.3, but many users have reported bugs after downgrading.
I537UCUCOC6 (5.0.1) Released 2015-04-21 - OFFICIAL
This post will be updated with the proper procedure for downgrading from OC6 firmware to other firmware once time permits. If you're looking for methods to update to the OC6 firmware, please see the other posts above.
How do I know which firmware I'm using. I recently just got this Samsung S4 Active with root but I really want to upgrade to the 4.4.2 update. I do have recovery mode working finally. Just need a pointer on which one I should download.

Remove the SIM? Never did that before- last update was from update.zip which was actually ON the SD card. Is this just an extra precaution for the fragile 'secure element' cards?

Exactly. Odds are that there won't be any problems, but when using Odin (a very powerful program) it never hurts to be overly cautious. I'm sure there are people out there that say nothing bad could possibly happen with the SIM card in, but I'd rather not take the chance. Ultimately it is up to the user, these are just my recommendations.
I can't seem to find the answer anywhere... Are any roms able to run on the ne3 firmware, or should I downgrade? Thanks in advance!

ODIN the stock firmware for 4.3, then use the ML2 modem fix, and use the OTA file, rename it to "update.zip" and use the stock recovery to flash it from external SD.
Use the stock firmware thread by @Devo7v under S4 Active General to obtain what you need. It should work so long as you dont like set your phone on fire somehow..

Thanks. If I wasn't headed out to dinner I'd have it done sooner. Man ART really takes a long time after an update to rebuild the binaries. LOL! But ART is definitely the way to go. Especially in light of the revelation that it's default in Android 5.0.
As promised, full image is up. Enjoy!
Looks like I got the OTA update today. Will it not work since I am rooted from your last full restore for 4.4.3?
It'll work fine if you've not modified anything. I sideloaded it while rooted.

I must be blind because I'm not seeing it I am on 4.4.3 but modified.
Yes you are missing it. The little link that says full rooted. Don't know what to tell you.
Sent from my XT1053 using Tapatalk
Would you mind posting link please?
Nvm. It is not under the full rooted header but instead the downloads header
Worked like a charm even with CWM and Xposed
Samuri, I am so, so grateful that you keep us updated on the I9505G! Thank you!
Just in case anyone else finds themselves in the same situation as me, I had used Samuri's previous Full Rooted Restore for 4.4.3 with ODIN (here), then installed CWM Recovery (via Heimdall) and installed the Xposed framework. Obviously I could not use the OTA update directly! But using ODIN to get this 4.4.4 image worked just fine.
My steps, in case anyone wants it spelled out:
Uninstalled Xposed framework from within the installer just to be safe. Settings are not removed. This step is likely unnecessary, but can't hurt
Used ODIN to flash the full 4.4.4 rooted image, verified working and rooted
Re-installed CWM via Heimdall. (When rebooting, CWM asks if you want to fix root. Yes)
Re-installed Xposed and rebooted -- previous Xposed settings reactivated with no problems
There were some nandroid backups made along the way as well of course, just to be safe.
The only place I had an issue, this time and the previous time, was finding the right Samsung USB drivers. The ones on the Samsung website are ridiculously out of date and a lot of the links I found were broken or suspicious. Maybe a good driver link is something that can be added to these posts, for people who are starting fresh?
Anyway, thanks again!
I had a link to ODIN and the samsung driver but the site I linked to was serving up malware so I pulled them. I'm hosting my own ODIN link now and I don't have the latest Samsung drivers. I wonder if sammobile has them. I bet it does.
If I uninstall root, will the phone still get the next OTA?
I'm pretty sure, but wanted to be 100% sure. Couldn't find a stock image that I could flash via Odin that wasn't pre-rooted.
Nor will you find a stock ODIN image that isn't rooted because Samsung doesn't release them for us. I have to manually create them. Root and the OTA have absolutely nothing to do with each other. I routinely flash OTA's on mine while rooted. Half the time I don't even lose root by doing so. Whether you choose to leave it or remove it won't have any impact on receiving the next OTA.

So I found out while I was on vacation. sigh. The site I was linking to had a malware infected version apparently. I've been using this version without issue for quite some time. It came from this site with all the versions included.
Custom kernel via odin?
Your image worked perfectly; thank you.
Have you ever run across a way to get a custom kernel as a flashable Odin image?
Looking for the alucard kernel..
Thank you sir for any information that you might have.
I imagine you could make a flashable odin image from it. There are some ODIN image tutorials/guides out there that you could follow. I have no experience with that personally.

Do you have a non-rooted version for the US I9505G. I need to return to stock as I have attempted to use "unroot", but Good for Enterprise is still saying my phone is rooted.
**Make certain that your reactivation lock in security settings is off before beginning this process**
1. Take the NG3 OTA update.
2. Download and install Towelroot-v3.apk(this version does not require internet access).
3. Place your phone into "Download Mode" (press and hold the Home, Volume Down, and Power keys until the phone powers on and displays warning screen, then press Volume Up key) and flash the G900A_ND3_Stock_Kernel using Odin's PDA slot(AP in Odin v3.09+).
4. Open the Towelroot app from your app drawer and press "Make it Rain" to root your device.
5. Power off then boot into "Download Mode" again and flash the G900A_NG3_Stock_Kernel also using Odin's PDA slot(AP in Odin v3.09+).
6. Install SuperSU to manage root access. Done!
Notes:
1. After flashing the ND3 kernel your phone may run a little wonky and towelroot may not root on the first try. If that happens reboot and try towelroot once again. Once rooted and after flashing the NG3 kernel your phone will once again run like a champ!
2. Following the above process will not affect your User Data or Knox Warranty Flag.
3. Should the NG3 ota update fail consider returning to stock NCE by flashing the G900A_Downgrade_to_NCE.tar using Odin's PDA slot(AP in Odin v3.09+) then taking the NG3 OTA update (or place the G900A_NCEtoNG3_OTA.zip onto your ext-sdcard and sideload from stock recovery). Once updated to NG3 continue from Step 2 above.
Alternative Method for Safestrap Users:
1. Place the G900A_NG3_100%_Stock_Rooted_ROM.zip onto your ext-sdcard.
2. Use Safestrap's Backup Function to back-up User Data.
3. From the Safestrap recovery perform an "Advanced Wipe" and wipe everything but your ext-sdcard.
4. Flash the G900A_NG3_100%_Stock_Rooted_ROM.zip using Safestrap's "Stock Slot."
5. Then press "Home" then "Restore" and restore User Data.
6. Once complete press "Home" then "Reboot" and reboot into "Download" mode.
7. Last, flash the G900A_NG3_Stock_Kernel.tar.md5 using Odin's PDA slot(AP in Odin v3.09+).
Notes:
1. The G900A_NG3_100%_Stock_Rooted_ROM.zip process will update your Modem, Non-hlos, System, Kernel, and Stock Recovery to NG3 but does not include the NG3 Bootloader.

No. I ODIN back to NCE, no root. Then I rerun update from About/software update. It does download 162MB file, then boot into AT&T logo. It will update until 30% and reboot, then the firmware is still NCE.
I am starting to think the file that people download from NCE is actually the same as those with ND3. However the file expects ND3 so it won't install (hence I get the error both with running the app and install in recovery). Notice all those people saying update fail in another thread?

Ahha! You have the wrong non-hlos.bin! I will package the NCE modem and send it to you. It should work after that.

The NCE Odin .tar that you flashed does not contain the non-hlos.bin. The non-hlos.bin is in the BL file in that set of .tars which the OP tells you not to flash. Likely beacuse if you are on the ND3 bootloader your wifi may go out or your phone may run wonky if you flash the NCE non-hlos.bin.
Here is the NCE modem pkg including non-hlos.bin. Flash in PDA or AP slot in Odin: G900A_NCE_Stock_Modem
Just go into stock recovery after flashing and re-sideload the NG3 OTA. I will put together an All-in-One_NCE_Odin.tar with the non-hlos so that other won't run into this issue. Someone will have to test.
I rooted with ping pong root, followed these guides to do my "OTA" updates:
http://forum.xda-developers.com/att-galaxy-s6/general/g920aucu2aof3-flashfire-update-t3156221
http://forum.xda-developers.com/att-galaxy-s6/general/g920aucu2aof3-to-of4-flashfire-update-t3181135
Then I used this file with Odin, to factory reset:
http://forum.xda-developers.com/att-galaxy-s6/general/odin-tar-files-sm-g920a-t3103835
Now it seems to have factory reset it but it says I have no IMEI, network unknown, etc....
I am suspecting that its something to do with those updates I did and flashing the Modem drivers, which maybe need to be downgraded now? or if i can update my software somehow with a legit version?
Any help is greatly appreciated.

To my understanding, the downgrade to OE2 from OE3 or OF4 causes these issues with the imei and such.
Sent from my SAMSUNG-SM-G920A using Tapatalk
from what I have gathered... seems right.
so I am thinking now if I can upgrade to OE3, or OF4 in a legit way... then my modem will work again....
but If i use the upgrades mentioned on those 2 threads, those are pre rooted? so ill just be rooted again (but working modem)
correct?
My files are working fine. the problem is that you're trying to keep root and the modem you flashed is NOT compatible with the bootloader you current have.
Sunderwear, no problem with your files at all, I think the problem is with me.
I am trying to remove root.
How can I put a bootloader on my device that will be compatible with my modem?
I had the same issues. I ended up using Odin to go to OCE, then OE2 then I used PPR to root, and used FF to go to OF3 then OF4. Cause a BUNCH of problemt so I went to BBuy and had them force a flash of the full OF4.
You could always try doing the Odin OI2 files and see if that leaves you fully updated with everything working. You will lose root and will not be able to downgrade.
Well, depending on your desired outcome (rootless OF4, or 5.1.1), you'll have to do slightly different things, both will wipe your phone completely.
To move to rootless OF4, just download the Full OTA from the bottom of the first post at this link this is where things get different.
The next step is to reboot your device to recovery, not download mode (hold power home and vol up). You may see a updating android icon, but nothing should be happening yet.
You should now see the manual menu for the recovery, select the sideload update option
On your computer with ADB, sideload the OTA zip Do not unplug your phone
Your phone should reboot and you're now running OF4 while rootless
For 5.1.1
Flash the ODIN files with ODIN
Please note, you must be already rooted for this to work: I made the same mistake of upgrading to of4. Here's what I did, and my phone works just awesome and is still rooted with the Of4 base band.
1. Odin 3.10.6 OCE2
2. Reboot, at this point you'll have no carrier signal/data.
3. Ping pong root, install flash fire.
4. Install Rayman's ROM, Clean ROM, or Dennis ROM with flashfire (wipe first!).
5. Download the of4 root update here. forum.xda-developers.com/att-galaxy-s6/general/g920aucu2aof3-to-of4-flashfire-update-t3181135 ONTO YOUR PC. unrar. Flash via Odin the two files you unrar'd according to these instructions:
In Odin put boot.tar.md5 in the AP slot.
Put modem.tar.md5 in the CP slot.
Leave all other settings alone and click start.
Reboot, and you should be up and running with cell data and carrier signal.

DISCLAIMERI am not responsible for any damage done to your device. The following guide is to be used at your discretion, you are taking the risk of rendering your phone unusable. It is also advised to Factory Reset while following this guide, so backup, backup, backup! Only attempt if you are confident in doing so!
Marshmallow to LollipopA recent development has allowed us to root the G900A/G870A on 5.1.1., which you can find here. There is a guide for G900A users to downgrade from 6.0 to 5.0, but I wanted to provide a guide for Active users to do the same. Once you have downgraded to 5.0, you can root using this new method, or update to 5.1.1 and root. I was regretting my upgrade to MM, it wasn't worth the cost of root and custom roms, so this was exactly what I needed to love this phone again. Now, on to the guide.
Step 1
Download the necessary files using the following links:
G870A OF3 ODIN TARBALL
ODIN 3.11
Step 2
I will make the assumption you have the Samsung USB Drivers installed and can see your phone in File Explorer. Extract both of the downloaded files wherever you'd like, you'll have an Odin folder, and four files from the tarball: BL, AP, CP, and CSC files. Put them in their own folder, just to avoid any mistakes with flashing. Run Odin as Admin and you'll see 4 slots, which you'll fill with the 4 tar.md5 files you just extracted. You'll load the tar files into their appropriate slots, IE AP_* into the AP slot, and you will encounter delays as Odin reads and verifies the files.
Step 3
As a precaution, it's recommended to have your phone charged to at least 75%. Now to restart the phone into Download Mode, you do so by powering off the phone, then power on the phone holding the Volume Down + Home keys. Once in download mode, hook the phone up to your USB cable attached to your PC. (Most failed ODIN flashes are due to USB cables, you may need to try a few)
Step 4
Go back to Odin and you should see your phone show up in COM box. Once you've verified that the phone is showing up, verify that you have all of the tar files loaded into the appropriate slots, and push Start. You'll see the progress as each file is flashed, look for any error messages. Once everything is flashed, your phone should reboot and you'll see a green pass. At this point, I recommend doing a battery pull or hold down Volume Down + Home + Power keys until the phone reboots. Once it shuts off, immediately hold down Volume Up + Home to boot into recovery. Now just do a quick factory reset, wipe the cache, and reboot. You should now be back to OF3, you can verify this in recovery, or by going to About Device under Settings, under baseband it should read G870AUCU2BOF3.
Step 5
At this point, you can use the previously mentioned guide to obtain root. If interested, once you have root you can head over to the Unofficial List of Roms and use FlashFire to flash a shiny new rom.
I'd just like to thank @AptLogic for his contributions, as well as @719c6 for finding the OF3 tarballs.
Thanks a lot! Just wanted to report I downgraded successfully and will try to work on rooting next. Thanks!

The lowest you can downgrade to is OF3, which you can do by following the guide. The OF3 firmware uses the same bootloader as MM, so we were able to downgrade, NE4 uses an older bootloader, and we are not able to downgrade bootloaders.
Sorry.

It was linked in the OP, but it's in this thread. Apparently, they're having an issue getting it to root now, so if you get it to root, report feedback on the thread and make sure to keep it. I was lucky enough to downgrade, root, and flash my favorite rom, Xtrestolite. Finally have my phone running nice and smooth again, I won't be jeopardizing my root on this phone anymore.
Good luck!

Are you using Supersume?
That app (it is paid) automatically uninstalls kingroot and replaces it with supersu, and as far as I know, you have to use it for everything to work properly.
Good luck!

Yea, refer to the linked root thread in OP, there was some modification to kingroot that broke the exploit. I haven't been there in a few days, not sure if they found a workaround yet.
It's unfortunate, but another method or workaround could pop up anytime.

I need more then that to go on. Off the top of my head, I'd recommend a different USB cable and also a verification that the PIT files were downloaded properly, as in, they aren't somehow corrupted.

Downloaded the files 3 times, and used 2 different usb.
With this guide could I change from the pb1 update? I'm on a g870a. If so what are my options?

Please, i want to know, does root work on this? I need root for my device. Thank
Just want to check, but for obtaining root I would follow Steps 1-6 in the OP linked guide and then do I follow through with Step 7 (flash 900a PreRooted OF3 ROM -- as described in the link) or do I jump straight to a new custom ROM?
If it helps, I'm trying to flash this ROM (XtreStoLite) to my 870a, which should work based on this post

Im already on OF3, but when I try to install the "combination" file from the guide you mention, ODIN doesnt install anything, tried different PC , usb ports, and usb cables aswell. is this the only way to get root? I mean it would be easier if we had a TWRP working for our device.
That's not for the active. It's for the 900A
