[How-To] Update to G900A_PA2 - 5.1 (Unrooted Stock ROM) - AT&T Samsung Galaxy S 5

**You can begin the following process from any Build/ROM but you must already have Root Access**
The 5.1 kernel's selinux hard enforcing prevents this build from booting when rooted. This means this build cannot be rooted! I created this ROM for those on previous, rooted builds that would like to try 5.1 while maintaining the ability to downgrade back to 4.4 and re-root at anytime. Enjoy!
**Required** FlashFire - Play BETA - PREVIEW
Download:
- G900A_PA2_Stock_ROMwTethering.zip
Previous Build:
- G900A_PA1_Stock_ROM.zip
1. Place the ROM onto your device (use either internal or ext-sdcard).
2. Open the FlashFire app and "Agree" to the Terms and Conditions.
3. Press "(+)" twice to bring up the "Actions" menu.
4. Press "Flash Zip or OTA" and locate and select the ROM. Leave "Auto-mount" unchecked under the "Options" menu and press the checkmark to continue.
5. From the main menu Uncheck all options under "EverRoot" and set "Reboot" setting to *"Download."
6. Press the lightning bolt then "Ok" to begin the **flash .
7. Once the flash is complete and the device reboots into "Download" mode, flash the G900A_OA1_Bootloader using Odin's PDA/AP slot.
*If you are already on the OA1 bootloader, set "Reboot" setting to "Normal" and skip Step 7.
**The screen will turn black then display the contents of your system before beginning the flash. FlashFire will pause for about 1 minute while flashing the "system" partition.
Once complete your device will reboot and pause on the AT&T splash screen for about 1 - 2 minutes before completely rebooting. Done!
Tip: for blazing fast speed turn off animations from Developer Options and reboot!
Recommended: Package Disabler Pro for disabling unwanted bloatware (root access is not required).
Known Issues:
- None!
Notes:
1. The above process will not affect your Knox Warranty Flag.
2. The process will update your Modem, Non-hlos, System, Kernel, and Stock Recovery. The bootloader will not be updated to allow for downgrading to previous firmware versions.
3. No need to wipe prior to flashing! The ROM will automatically wipe UserData.
4. If you do not already have root access (or to unbrick) you must flash the G900A_Downgrade_to_NCE.tar using Odin's PDA/AP slot (Caution! Do not flash if you have taken the OC4, OF2, OF3, OI5, PA1, or PA2 ota updates!) and root with TowelRoot, before continuing with the above process.
5. To learn more about FlashFire's capabilities on locked bootloader devices see here: http://forum.xda-developers.com/showpost.php?p=60070810&postcount=2

Thank you so much @muniz_ri boss.

Hopefully we will see some 870A instructions lol

Well done muniz_ri. Ditto on the Active!

Will this work on oc5 bootloader @muniz_ri ?

since I'm on 4.4.4 still can I make a slot in ss and install it there

Now installing

Thank you for this, running well so far with root. Will try xposed in 36h or so.
Edit: Su removed on reboot. Guess it was never rooted.

I didn't do any over the air update just use the forum here

So now u used this process to get 5.1.1

Yes when I first got the phone I used this link to root http://forum.xda-developers.com/showthread.php?t=3021120 been on 4.4.4 with ss and ff then used ff to flash 5.1.1

And muniz mentioned there this is unrooted version of 5.1.1 becase it is unrootable we dont have root on this 5.1.1 if u need root u have to go back to 4.4.2 and root

Galaxy S4 Active 4.4.2 Kitkat ROOT

Hello everyone. It's me again now this time I bring you root access to the new OTA KITKAT for our S4
Disclaimer : I'm not responsible if your phone suddenly dies, explodes or your cat catches fire. Be warned.
SOME PEOPLE REPORT MOBILE DATA NOT WORKING AFTER THIS PROCESS SO ALL YOU GOTTA DO IS GO INTO YOUR APN SETTINGS MENU AND DO RESET TO DEFAULT SETTINGS AND WRITE YOUR CARRIERS APN SETTINGS AND IT WILL WORK.
This process has a lot of steps but if you follow them correctly you will end up with stock rooted 4.4.2 kitkat with super user and safestrap
Requirements:
If you already took the update and your system version is 4.4.2 keep reading.
1. Patience
2. Pwned Kitkat OTA Update link
3. Pwnedkernel for 4.3 Download
4. System image from stock 4.3 Tar file Download
5. Safestrap for the Galaxy S4 Active Download
6. Stock 4.4 Kitkat Kernel Download
7. Chainfire's SuperSu.zip Download
First after you finish downloading the stock 4.3 image extract it somewhere you remember and you'll see the following files:
BL_I537UCUBML2_2244695_REV06_user_low_ship_MULTI_CERT.tar
AP_I537UCUBML2_2244695_REV06_user_low_ship_MULTI_CERT.tar
CSC_I537UCUBML2_2244695_REV06_user_low_ship_MULTI_CERT.tar
CP_I537UCUBML2_2244695_REV06_user_low_ship_MULTI_CERT.tar
Put your phone in download mode and fire up odin. Under PDA select and flash
AP_I537UCUBML2_2244695_REV06_user_low_ship_MULTI_CERT.tar
This will downgrade your system back to 4.3 because yes the new kitkat bootloader allows you to flash 4.3 signed firmware. Note: YOU CANNOT DOWNGRADE BOOTLOADER SO DONT ATTEMPT IT
Wait until odin finishes flashing the firmware and when the phone reboots itself put it again in download mode. Now you must flash pwnedkernel.tar.md5 selecting PDA again in ODIN and wait for phone to boot up. If your phone gets stuck in the ATT logo then perform a factory reset .
Once your phone boots up enable USB debugging mode and root it using saferoot or vroot. GOOGLE it and you'll find it...Then you must install safestrap.apk
adb install safestrapactive.apk
Click to expand...
Click to collapse
Now copy pwnedkitkat.zip and update-Supersu.zip to your SD Card and once that's finished open up safestrap in your device and tap install when that's done tap reboot to recovery.
Now you'll be at the safestrap recovery screen so go ahead and select install zip file.
IMPORTANT : DO NOT DELETE DATA/CACHE OR DO A FACTORY RESET BEFORE FLASHING THE KITKAT.ZIP OTHERWISE YOU'LL HAVE TO START ALL OVER AGAIN.
Install pwnedkitkat.zip and once it finishes go ahead and install update-supersu.zip to enable root access.
AND FINALLY VERY IMPORTANT YOU MUST FLASH THE 4.4.2 STOCK KERNEL IMAGE USING ODIN AND SELECTING PDA OTHERWISE YOUR PHONE WONT BOOT
Wait for your phone to reboot, open up superuser and disable knox security.
Enjoy your rooted 4.4.2 S4 Active.
Credits : hashcode for making safestrap possible and the other amazing developers at XDA that discovered these exploits in the past and special thanks to Samsung for "letting" open these loopholes
If you are in official 4.3 ML2 see my next post.

Thank you!
Can't wait. When is the ETA? estimate, 10 minutes?
I just can't wait transforming my S4 to S5!
Edit: 40 minutes passed
Now it is probably close to me. I can feel it!
THANK YOOOOOOU!!!!!!!!!!!!!!!!!!!!!!
If you're currently running 4.3 ML2 official update and you want to upgrade to 4.4.2 but dont want to lose root then keep reading.
In the following steps I'm assuming that you're currently running stock 4.3 Rooted ...see my other guide...and that you didn't modify any system apps otherwise the update will fail and you'll have to restore using the Odin package for 4.3.
1. Download pwnedkitkat.zip from 1st post.
2. If you dont have safetrap installed then you must download it and install it.
3. Copy pwnedkitat.zip and update-superuser.zip to your sdcard
4. Restart your phone in safestrap recovery and install pwnedkitkat.zip and when it's done flashing install superuser.zip.
WARNING : DO NOT PERFORM A FACTORY RESET BEFORE FLASHING THE ZIP. THIS IS A MODIFIED OFFICIAL UPDATE SO ONLY SYSTEM FILES WILL BE UPDATED. YOUR DATA WILL BE UNTOUCHED.
5.Put your phone in download mode and flash the 4.4.2 stock boot.tar.md5 kernel and your phone will boot after a few minutes with root access enabled.
Enjoy.
Deleted. As I managed to do it.

You guys should try flashing the 4.3 Odin package and starting from there. I know I have a lot of modified system apps, so I'm likely going to re flash 4.3 just to make sure I'm stock. Thanks again sunderwear!! Good luck rooting everyone. I'll post back with an update in a bit!!

what about us 4.2.2 stock rooted users?
I'm sure most S4 Active owners are still on 4.2.2 rooted. What is the best procedure for us?
Should i unroot my phone via SuperSU then accept the stock 4.4.2 OTA update, then follow the method in the OP?
Or can i leave it rooted and flash stock 4.4.2 via Odin and then follow the OP?

I was in a similar position with being rooted on 4.3 ML2 (Sunderwear's method). I unrooted thru SuperSU, unfroze everything under TiBU, unchecked every module under xposed framework, reboot phone then proceeded to uninstall all my root apps. I then did a factory reset, then I flashed back to the stock 4.3 under ODIN and following that I took the 4.4.2 OTA successfully.
In the end it's up to you, but IMHO I consider it wise to begin anew with a fresh clean phone.
Yes if you get stuck after downgrading system you must do a factory reset otherwise you'll get stuck in the ATT LOGO.
sunderwear thank you I downloaded it kitkat zip file. I flashed it with safestrap and then I flashed suprSu then I reboot the phone won't boot ... I flushed with Odin the kernel 4.4.2 every things works greats

[How-To] Root GS5 Active - G870A_OA1 - 4.4.4 (2/7/2015)

**Make certain that your reactivation lock in security settings is off before beginning this process**
1. Take the OA1 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 G870A_NE4_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 G870A_OA1_Stock_Kernel also using Odin's PDA slot(AP in Odin v3.09+).
6. Install SuperSU to manage root access. Done!
Troubleshooting:
1. Should the OA1 OTA update fail consider flashing the G870AUCU1ANE4_Full_Odin.tar to return to factory stock then take the OTA updates to OA1. Or, place the G870A_NE4_to_NG3_OTA.zip and G870A_NG3_tA1_OTA.zip onto your ext-sdcard and sideload each file from stock recovery beginning with the G870A_NE4_to_NG3_OTA.zip. Once updated to OA1 continue from Step 2 above.
2. When flashing the kernel the most common cause of an Odin flash failure is a bad usb port or cable. Please check before reporting a failure!
Notes:
1. The above process will not affect your User Data or Knox Warranty Flag.
2. After flashing the NE4 kernel your phone will 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 OA1 kernel your phone will once again run like a champ!
Alternative Method for Safestrap Users:
1. Place the G870A_OA1_100%_Stock_Rooted_ROM onto your ext-sdcard.
2. From Safestrap recovery press "Backup" and backup your User Data.
3. From the main menu press "Wipe" then perform an "Advanced Wipe" and wipe everything but your ext-sdcard.
4. Next, press "Install," then select and install the G870A_OA1_100%_Stock_Rooted_ROM.
5. Once complete, press "Restore" and restore your User Data.
6. Last, from the main menu press "Reboot," then "System." Done!
After following the above process your phone will pause on the AT&T splash screen for about 2 minutes before rebooting.
Notes:
1. The above process will not affect your User Data or Knox Warranty Flag.
2. The ROM will update your Modem, Non-hlos, System, Kernel, Stock Recovery, and Bootloader to OA1.
3. The "Backup" and "Restore" steps in the instructions are not mandatory but will greatly reduce your device's set-up time. All currently installed non-system apps and settings will be automatically restored.
4. The ROM does not contain BusyBox which is required by the Safestrap.apk. Download the BusyBox Installer to re-install BusyBox.
Let me be the first to comment...I rooted doing this but since I was already rooted I had to Odin back to ne4 then ng3 (sideload or ota, what ever works) and then update to oa1 (sideload or what ever works). After that, everything is exactly as the tutorial says.
Sent from my SAMSUNG-SM-G870A using Tapatalk
Did you have to revert just the kernel or the whole ROM before you could install the OTA update? I'm currently Towelrooted on NG3 and patiently awaiting the OTA download.

I had to Odin the whole ne4 Rom and then from there use the ota update files to get to oa1 and then use the kernel trick to root with towelroot. Other wise it kept giving me signature errors even if I Odin'd just the system partition

Can anyone tell me whether the G870AUCU1ANE4 full odin tar file will reinstall previously deleted system files or not. I was thinking of using titanium backup to remove a lot of bloatware but want to know first if this will get me back to stock with all factory equipped apps. When I flashed this full odin tar so that I could update and then reroot, my home screen and all my apps went unchanged so I'm skeptical to believe it's similar to flashing the phone back to stock.
thank you for any help

So it will replace deleted system apps but leaves user installed apps alone?
Will performing a factory reset on this phone replace deleted system apps?
The phone i had prior was an s2 and when using odin to flash it with a stock rom, it would be similar to factory resetting it but when i flashed the full ne4 on this one, I still had all my apps and home pages, settings etc. I know the flash worked cause i was able to install the update that i couldn't before flashing due to towelroot.
I just realized the full ne4 file linked to in this thread (.rar zip file) isn't exactly the same as the stock firmware file available from sammobile (zip zip file). Is the ne4 .rar file linked to here modified to leave the users apps and settings alone?
Thanks. Worked great. :good:
I used safestrap. Very easy, after days of annoying update notifications.

I hadn't looked at the one on here but if it's a .tar.md5 then flashing through Odin should reset it back to ne4 stock out of the box with everything. I used the firmware to fully go back to stock

I installed ND via Odon, made it rain, rebooted, & am still on 4.4.4 (0A1A or something of the like.
Didn't even have to follow (or get to) the step to Flash newer kernal to get back to 4.4.4. Thanks all involved

You were right bigwillg. Didn't really get a chance to test it 1st. After noticing choppy stuff & a bigger than usual battery drain, I "Odin'ed" the newer kernal. Now its like butter. Still on stock ROM with frozen bloat stuff. Considering uninstalling em all together at a future date. Gonna get to know my phone 1st I guess.
In case I didn't already hit thanks on OP, I soon will. And on a side note THANK you for this topic/forum.

Unable to install latest OTA
My G870A was rooted before the previous OTA was sent.
This latest OTA gets to about 27%, then fails.
I have looked around to see how to fix this, yet I can't seem to find anything.
The steps here start with the OTA, so they're currently useless to me.
I have tried going back to 4, but towelroot has no way to remove root once set.
SuperSU mentions a removal of root, but it appears to be just to uninstall itself.
Anyone have any ideas?

The sequence is silly, but whatever.
I started with 4.4.4, rooted, safestrap. Very light root usage - props file changed to enable SD card usage for more apps, logon sound replaced with silence, TiBu (with bloatware/et. al. frozen but not removed), ServiceDisabler, Busybox, Safestrap. Otherwise stock.
Made safestrap and Kies backups.
Used your zip under safestrap to wipe and restore, rebooted w/o odin flashing the boot/kernel from you the first time (didn't catch the reboot fast enough).
After allowing the device to sit black-screened for a few minutes to make sure I wasn't being impatient, I powered down, brought it up into download mode, and ODIN flashed your second step (bootloader/partitions/whatever else is in that flash).
Power cycled phone, it again locked up black-screen without getting even the Samsung animation.
Waited a few minutes to to be sure, and power cycled again to be sure.
Brought phone up, used ODIN to flash the 'downgrade to NCE' package.
Power cycled, phone booted normally, let it go into setup sequence but skipped everything until I could tell it to shut down.
Brought phone up, used ODIN to flash the next two OTA files to bring it to 4.4.4.
Again, power cycled, phone booted normally, let it go into setup sequence but skipped everything until I could tell it to shut down.
Brought phone up, used ODIN to flash the 5.0 OTA.
Brought phone up, runs as expected (of course, no root).
Addendum. I have extra fun with ODIN because my PC runs Ubuntu Linux, so I use Odin within Win 8 running inside VMware Player. Seems to work fine but I would never guarantee it doesn't introduce quirks.
I may at some point in the next couple weeks backstep and again try your safestrap based root-keep setup, but want to take some time with it 100% stock and see how things run.
Cheers.

The sequence is silly, but whatever.
I started with 4.4.4, rooted, safestrap. Very light root usage - props file changed to enable SD card usage for more apps, logon sound replaced with silence, TiBu (with bloatware/et. al. frozen but not removed), ServiceDisabler, Busybox, Safestrap. Otherwise stock.

Thank you, but based on what you have stated you never flashed the OC4 bootloader which explains why you were able to downgrade.
At this time there is no downgrade method for those that have taken the OC4 ota update.

YES! If your phone is on official ATT 5.0 OTA, then there is NOT a way to root or even downgrade to NCE. You will have to wait until root exploit is found or bootloader unlocked.

STEPS I TOOK TO ROOT.
You will have to start from scratch and factory.
Download on your pc and flash in download mode the G900A_Downgrade_to_NCE.tar using Odin's PDA slot(AP in Odin v3.09+) This will bring device to stock factory.
Setup you phone first use.
Download and place the G900A_NCE_to_NG3_OTA.zip onto your ext-sdcard and sideload from stock recovery.
Flash the G900A_ND3_Stock_Kernel using Odin's PDA slot(AP in Odin v3.09+).
Install Towelrootv3.apk and run app and update SuperSu
Install safestrap.
Make a nandroid backup with safestrap To ext-sdcard.
Extract the G900A_OC4_Stock_Rooted_Backup folder from the .rar archive and place it into the following folder: ext-sdcard/TWRP/BACKUPS/xxxxxx, fyi...the name of this folder will vary.
From Safestrap recovery press "Wipe" then "Advanced Wipe" and wipe everything but your ext-sdcard.
From the main menu press "Restore," then select and restore the G900A_OC4_Stock_Rooted_Backup.
Once complete from the main menu press "Reboot," then reboot into "Download" mode.
Last, flash the G900A_OC4_Stock_Partitions_wOA1_BL using Odin's PDA slot (AP in Odin v3.09+) and reboot.

Stop giving wrong information! Did you read the OP? This is about downgrading stock OTA 5.0 and not rooting. You cannot downgrade if your phone is on official stock OTA 5.0……! You will brick your phone. The information you have provided only works if your phone is Still on NG3 or OA1. Again if your bootloader is already on OC4, then you cannot downgrade. The reason @muniz_ri method can be downgraded is that he using a 5.0 ROM while keeping the bootloader at OA1.

If you need help I solved my soft brick. Put your phone into download mode then flash the stock kernal using odin. Reboot then flash using odin the stock partition. While this wont downgrade to 4.4.X because you are on ota 5.0 you will be able to get your phone back to 5.0 lollipop. Thanks to Fitz110 who uploaded these files and for the solution.

Great work! Glad to see there are still some developers left for this device!
Just curious - for the modem only, I see it includes non-hlos.bin and mdm.bin. What does apnhlos.bin do, and why is it not included in the modem tar? I also noticed previous modem-only's have not included apnhlos, but I am wondering if we are missing out on added functionality by not keeping that up to date as well?
Thanks.
It is compatible with TWRP, but I assume it isn't compatible with Philz Recovery(CWM), correct?

The non-hlos is the lte portion of the modem and you can get away with it on unlocked bootloader devices but still a good practice to have all matching partitions in my opinion.

Yes, it will replace your custom recovery with stock OD2.
The idea was to share a way to update to stock, rooted OD2 without first having to Odin back to stock to successfully take the ota.
You can then reflash Twrp after flashing the ROM or continue using FF for flashing zips/backups, etc.

So I was referenced here by the main thread: http://forum.xda-developers.com/gal...ginal-galaxy-s4-update-zip-od2-t3105607/page5
I rooted a long time ago but went back to stock (through recovery) about a month ago. I'm attempting to update to OD2 but I keep getting error 7. Can I just download this zip and push it via ADB?

[GUIDE] Root, ROMs, and Other Cool Stuff

Rooting the G900A
*Note for Mods: if you could sticky this thread that would be great, I think its really helpful
NO THIS DOES NOT WORK ON THE G870A
Updated with even newer-er method on 03/04/2017
DISCLAIMER:
Code:
Your warranty is now void. I nor XDA is responsible for the effects this may have on your device or your life, whether that be bricking, loss of data, combustion, nuclear war, or the election of businessmen as President (wait what).
Remember, its not root that puts your device in danger, its how you use it.
If you don't know what a locked bootloader is, or think that Chainfire is a new video game, you shouldn't be here, go read a little about Android and the Galaxy S5 before continuing
So let's begin:
What You'll Need:
This *experimental* firmware: https://androidfilehost.com/?fid=745425885120704448 (Thanks @NavSad !)
The SuperSU APK, Towelroot, and FlashFire, all available from this zip: https://www.androidfilehost.com/?fid=673368273298935990 Mirror
This modified "from-noship" pre-rooted OF3: https://www.androidfilehost.com/?fid=673368273298933039
What To Do:
Step 1: Goin' Wayy Down
Use ODIN to flash the experimental firmware.
MASTER CAUTION: This will wipe ALL data on the device!! Backup your stuff before proceeding. I nor XDA is responsible for loss of your memes!
Simply flash the .TAR.MD5 file in the zip using the AP slot in ODIN, and then wait for the phone to boot (which is literally all of 10 seconds).
Step 2: Our Old Friend
After the OS is installed, go to the file manager and install Flashfire, SuperSU, and TowelRoot.
Run towelroot. Simply hit "make it ra1n" and 3 seconds later you'll have the root binaries installed.
Now open the SuperSU app and hit "new user", let it do its thing and then update the SU binaries (don't worry, its safe to reboot!)
At this point you've got root! Now, let's get back to the present!
Step 3: Back to the Future!
Open FlashFire, grant it root access, and flash the modified OF3 with these settings:
Mount /system read/write
A wipe isn't required, but it is recommended (if you do wipe, make sure to put that card B E F O R E the flash zip/ota card!)
Hit "flash", let it flash, reboot, and load.
Guess what? You're done! That's right, you've done all the steps!! Simpler than before, right?
The OLD Method:
This method is not recommended and is only here for historical purposes.
--TESTED WORKING ON BASEBAND G900AUCU4COI5, if ya don't have it, go get it!--
WARNING: THIS ROOT METHOD ONLY WORKS ON BASEBAND VERSION G900AUCU4COI5, IF YOU DON'T HAVE IT, GET IT IN POST #2!
ANOTHER WARNING: THIS IS A TEMP ROOT ONLY, REBOOTING WITHOUT FLASHING THE PREROOTED OF3 WILL RESULT IN A BOOTLOOP!!
Bootlooped? Flash the AP file in the OI5 repair ZIP to get going again. Flashing the AP slot ONLY will save your data
Here's some instructions to get you going:
STEP 1.
Install:
- Kingo ROOT v4.1.9
- KingRoot v4.8.1
- SuperSU
- SuperSUme v6.0
- FlashFire
- Any Root Checker app
STEP 2.
Disable these:
- WiFi
- Location
- NFC
- Sync
- Powersave mode of any kind
STEP 3.
- Open KingRoot
- It will say "root method available", click the blue root button, the process will fail ***THAT IS OKAY***
- Root using Kingo ROOT v4.1.9
It will also fail **THIS IS OKAY**, what this is doing is installing the binaries for KingRoot to hijack.
NOTE: Kingo ROOT must not show Install Recommended App below Android version.
If it does, you didn't disable the above toggles. Clear from Multi-Task and start this step over.
STEP 4.
- Open KingRoot v4.8.1
It should show you the Security Index page where you see the big blue numbers. Press the button saying Fix Now/Continue.
Let it run its course...
STEP 5.
- Uninstall SuperUser (installed by Kingo ROOT)
Just press and hold the app in the app drawer and drag to uninstall. Simple step.
STEP 6.
- Open Super-Sume
KingRoot should ask you for permissions. Allow it.
Tap the big blue button and let it run.
Congratulations, you've got temp root!
STEP 7.
- Use FlashFire to get on the PreRooted OF3 ROM (zip is in Post 3)
Flash Order:
- Wipe All (Wiping internal storage is recommended but not required).
- Select the pre-rooted OF3 zip
Upon selecting, an options screen pops up. Toggle Mount /system read/write.. Important..
Begin the flashing process.
* Why do I have to use KingRoot 4.81? KingRoot 4.82 and above blocks the use of Supersume.
Thanks @NavSad, @DejaVuAgain, and everyone else for their help and hard work!
COI5 Rollback Zip
Now that we have root, we're obviously gonna attempt a ROMing of the phone. But, sometimes (most of the time) this can go awry and leave you with a $4-600 paperweight.
Get the ODIN-flashable zip for G900AUCU4COI5 here: https://www.androidfilehost.com/?fid=24438995911970945
BOF3 Rollback Zip
Thanks @NavSad for finding and uploading an ODIN-flashable copy of STOCK OF3!
Get the ODIN-flashable zip for G900AUCU4BOF3 here: https://www.androidfilehost.com/?fid=529152257862696776
How to Roll Back
Step 0: Make sure you have the Samsung USB Drivers installed on your PC, if they are not installed get them here: http://org.downloadcenter.samsung.c...G_USB_Driver_for_Mobile_Phones_v1.5.45.00.exe
Step 1: Get ODIN 3.11.1 using this link: http://forum.xda-developers.com/attachment.php?attachmentid=3813736&d=1468609625
Step 2: Get the ODIN-flashable zip for G900AUCU4COI5 using the link above.
Step 3: Extract both zip files to a temporary location.
Step 4: Make sure your phone is at least 75% charged, then power it off and boot it into download mode with these steps:
Step 4a: Hold down the VOLUME DOWN, HOME, and POWER buttons.
Step 4b: The phone will boot with a warning that says "A custom OS can cause critical problems... blah blah blah", press the VOLUME UP button.
Step 5: Connect the phone to your PC and launch ODIN
Step 6: Put the appropriate .md5 files in their slots (the one beginning with BL goes in the BL slot, AP in AP, etc). When putting the AP and CP files in their slots the program will hang while it checks the md5 hash. DO NOT PANIC!! This is normal, give it a minute or two and it'll move along.
Step 7: Ensure all the right files are in their slots and click "Start" to begin flashing. WARNING: DO NOT unplug the USB cable during flashing. This can potentially result in a hardbrick! Ensure that your computer has an adequate power supply to prevent errors!Do NOT mess with the "Options" tab. These are for expert developers only and inappropriate use of them can result in a hardbrick!
Step 8: The phone will restart after the flash is complete, and the ODIN screen will light up green with "PASS" in bold lettering. It is now safe to unplug the USB cable. Just let the phone reboot and do its thing. It will hang at the AT&T logo for a bit. This is normal, but if it stays there for 30 minutes or more, pull the battery out and restart the device.
Do NOT attempt to flash a custom OS or earlier releases of Android! You will get an auth error (if flashing a custom OS) or and aboot fused 4 > binary X error (if flashing a previous version of Android).
Flashing ROMs
I have stayed up over 8 hours experimenting, bricked my device about 3 times, and probably lost a couple panoramas from New York to bring you guys this guide!
It is now possible to flash G900A ROMs from ANY BASEBAND VERSION!!!
This is a 2-step process, your phone will be flashed and wiped twice, so back up all of your data before proceeding. I'm not responsible for the loss of your memes because you didn't back up!
Part 1: Going back to good ol' 5.0
Guys, this step is MANDATORY!! If you don't do this step you could lose your root and/or SOFTBRICK!
In this part we'll be flashing your OS down to G900AUCU4BOF3, pre-rooted stock, using FlashFire by Chainfire.
Prerequisites:
Rooted using the guide above.
Download FlashFire from the Play Store
Download the G900A_OF3 pre-rooted stock ROM from here: https://www.androidfilehost.com/?fid=24052804347788226
Put said OF3 zip on your phone's external SD or internal storage.
Okay, time to flash!
Go to FlashFire, tap the "+", select "Flash Zip or OTA", find and select the OF3 zip, leave "auto-mount" unchecked.
Uncheck ALL EverRoot functions. The ROM is pre-rooted.
Set reboot setting to "Normal"
Tap the lightning bolt, tap OK
The device will flash and reboot, go to AT&T Splash for 1-2 minutes, and then completely reboot.
That's all of Part 1, pretty simple lol.
Part 2: Custom ROM time!
Prerequisites:
Install FlashFire from the Play Store
Download your custom, G900A ROM (in this example we are using Alliance 8, https://www.androidfilehost.com/?fid=23991606952596246
Put said ROM in your phone's storage (Internal Storage or External SD)
Time to flash!
Go to FlashFire, tap the "+", select "Flash Zip or OTA", find and select the ROM zip, leave "auto-mount" unchecked.
Uncheck ALL EverRoot functions.
**CRUCIAL** Tap the "+" again, select "Wipe", and check every box EXCEPT "Internal Storage", then tap OK.
Arrange the "Flash Zip" and "Wipe" cards so that "Wipe" is before "Flash", FlashFire likes to put it the other way around, and if you let it do so, you've got yourself a softbrick and have to ODIN back to OI5 and start all over.
Set reboot setting to "Normal"
Tap the lightning bolt, tap OK
The device will flash and reboot, it will stick at the splash screen anywhere from 2-8 minutes (mine stuck around 4).
That's it! You've got yourself a nice, shiny new ROM to use!
Please remember to leave a thanks if you found this guide useful! Enjoy being able to ROM like all the other S5 variants!
ROM Index
These ROMs should work using the guide above. To be put on this guide, the ROM must meet these requirements:
Be on the OC4/OF2/OF3 Kernel or Above
Be tested on an AT&T S5 by an xda user with screenshots of the About/Software Version, Home, Lock, and Notification screens.
Be flashable with Chainfire's FlashFire
To request that a ROM be added to this index, please post a reply in this thread and mention @AptLogic. Links to screenshots are required or you will be ignored (not trying to be mean, its part of the requirements)

Attention:
After you flash a ROM for another G900 variant, you have to replace the kernel via Odin. This is because the kernels that these ROMs come with don't work with our locked-down versions of Android. To replace the kernel, put your phone in download mode (Vol. Down + Home + Power) and flash the OC4 kernel in the AP slot in Odin.
In most of unofficial ROMs, you will have to manually install the Google Play services 10.0.84 and Google Play Store 7.3.07.K-all [0] [PR] 139935798. For that, download the .apk, transfer to your phone or SD card memory and install it via some file manager. Remember that you have to go into "Security" and enable "Unknown Sources" in your settings.
ROMs That SHOULD Work
These ROMs most likely work with the G900A, but are pending screenshots from a user to verify. Feel free to give em a try if you feel adventurous!
Again, if you would like to request that a ROM be added to the index, please post in this thread with appropriate links and screenshots, and mention @AptLogic in the post.

Well it seems that with Kingroot 5 it doesn't let super sume run on most devices. I had a problem with using it with KR 5, so I had to do the whole downgrade thing.
I'm also gonna try Phoenix, just moving files off my device and I'll flash it
I heard they blocked super sume on the new kingroot
Will this method work on G900AUCS4CPA4?
No only OI5

You can try it on CPA4, we really don't know yet but if you can get as far as root you should be fine.
Go ahead and try it and tell us

You need to use SuperSume to get SuperSU. You can get it from the Play Store for $3.99 (I think), or you can look for an APK on xda somewhere. You need to make sure you have Kingroot 4.81 or it will reject SuperSume and it won't run.

Kingroot now works on the Galaxy S5 Running OI5
DISCLAIMER:
Code:
I nor XDA is responsible for the effects this may have on your device or your life, whether that be bricking, loss of data, combustion, nuclear war, or the election of businessmen as President (wait what).
Remember, its not root that puts your device in danger, its how you use it.
--TESTED WORKING ON BASEBAND G900AUCU4COI5 AND BELOW--
Here's some instructions to get you going:
Install KingRoot 5 from http://kingroot.net
Now, this is where it gets weird: You have to keep running KingRoot until it works. It took someone 2 tries, took me 10 or 11. The phone will keep restarting but eventually you will have root!
After you are rooted: REMOVE KingRoot 5, and replace it with KingRoot 4.81 (found here: http://forum.xda-developers.com/devdb/project/dl/?id=17153
You have to do this to run Super-Sume without it hanging at the "Processing, please wait" part.
After installation, run the root again. Your phone should restart once and you will be rooted again (if it takes more than one try that's okay).
Get Super-Sume from the Play Store.
Run Super-Sume and bask in the joy of having SuperSU on your G900A
I hope to see an uptick in the development for this variant now. Maybe we'll finally get Nougat on it XD
Another Disclaimer: I did not personally find this out first. I'm just putting it in an easy to use guide so you don't have to go through about 12 pages of a different thread to find these instructions. Thanks to @lingo2012 for figuring out that Kingroot works.
Post replies saying which ROMs work with the ATT S5 so we can get a list going!

Can we get Safestrap working?

I was just testing that. I managed to get Safestrap to work by just installing busybox and then safestrap. Unfortunately I bricked my device soon after trying to install Phoenix ROM and I'm waiting for it to restart XD (Update: Debricked successfully, PM me if you need the OI5 restore files )
If I do find a way to install a ROM, the instructions (as well as a list of compatible ROMs) will be put into Reply #3 in this thread.
If we could get one of those Nougat ROMs to work that would be AMAZING.
I stopped updating OF3 back when @muniz_ri was the one leading the charge. Is there a preferred method to OI5 (or PA2?) that will allow for trying out this root method while preserving the ability to get back to rooted OF3?

No, sorry. But if you're already rooted on OF3 you may as well just stay on it until we can figure out ROMing on phones with newer basebands.
Okay SO after THREE bricks (count em), I have come to the conclusion that ROMing this phone on Lollipop with Safestrap is NOT POSSIBLE.
At this point I'm going to invite @Chainfire to the party, maybe he can give us a helping hand. There is a possibility that we can use Flashfire. I'll probably try that next. I plan to be up pretty late working on this.
If anyone else wants to share input please do. Right now I'm trying to flash the Resurrection Remix 7.1 ROM.
Yeah i tried with flashfire but it just sat at the Galaxy S5 screen.

Is there any chance of bricking the phone if i try to root CPA4?
Can anyone help me with this? I am currently on CPA2 and I can run kingroot 5.0 and then uninstall it to run 4.8 and re root which works fine. Then I run Super-Sume and that works fine too it installs SuperSU but then SuperSU asks me to update which I do and it reboots after a successful attempt and I am no longer rooted. Has anyone had this issue?
