Help Needed - Downgrading 4.4.4 to 4.3.2, and Rooting after downgrade - I337UCUFNJ4

So AT&T recently force pushed the I337UCUFNJ4 (4.4.4 kitkat) update from the previous 4.4.2 version, and I am not too thrilled about this. I really want to downgrade it back to 4.3 (jellybean) if possible with a root. Not sure what the best order in terms of downgrade and root is. But is it possible to downgrade it now and I know there a way to root the new pushed version (4.4.4 - http://forum.xda-developers.com/gal...to-root-i337ucufnj4-4-4-4-11-13-2014-t2939553). Please guide me in the right direction in terms of the steps to do the downgrading.

I checked out that link you provided, however that says I can go back to MK2 only if I started out with MLD, MK2 or an earlier base? Is there still no way to revert from 4.4.4 or 4.4.2 to 4.3.2?

then I followed the instructions on this post (to downgrade from 4.4.2[NB1] to 4.3.2[MK2]):
http://forum.xda-developers.com/showpost.php?p=50667360&postcount=1
After that, the attached image shows the current setup I have on my phone. Is that how its supposed to be after doing the downgrade (baseband version: NB1 and build number: MK2)? Also, after using saferoot, would I be able to uninstall the regular stock apps? If so, it does not allow me to do so...
Also, Wifi and 4G/data network wasn't working after doing all those steps so I added the apn settings for my network and 4G was enabled, so that's working fine.
However I am still not able to get wifi working on my phone. I have no idea how to load the bypasslkm exploit into my phone to get the wifi working. Could someone please explain to me how exactly I can do that. I read somewhere else on the forum that it could be flashed through safestrap, however I am not sure what file can be flashed, and how to flash through safestrap. If there is any other way, please provide some details as I am doing this for the first time.

[Q] Help root S5 G900V, after NCG flash unit wont boot up to continue next step.

Using the following method to Root Samsung Verizon s5 when I get step 5 and flash the NCG my phone will not boot fully and just keep resetting but will not completely boot up. what do you suggest?
1: Download the RootS5.zip file and unzip it to your desktop.
2: Copy tr_v2.apk, BusyBox.apk, Safestrap-G900V-3.75-KitKat.apk and UPDATE-SuperSU-v2.45.zip to your extSd card on your phone.
3: Run Odin3 and load G900V_NCG_Stock_Kernel.tar.md5 in the AP slot. Towelroot will not work with anything newer than NCG.
4: Shut your phone off and enter download mode by holding down the power, home and volume down buttons until it boots to download mode and then press the volume up key.
5: While in download mode connect yoUr phone to your PC and Odin should say you are connected. Now press the start button to flash G900V_NCG_Stock_Kernel.tar.md5 to your phone. The phone will now reboot and update some apps, let it finish. After this there will be a bunch of force closes. Just close them until they go away
6: Open your file browser, go to tour extSD, install and run tr_v2.apk, BusyBox.apk and then Safestrap-G900V-3.75-KitKat.apk in that order.
7: Shut down the phone, enter download mode again, flash NI2_stock_kernel.tar.md5 or whatever kernel you were on in step 1 and reboot into safestrap.
8: While in safestrap install UPDATE-SuperSU-v2.45.zip from your extSD card and reboot.
If all went well you should be on your original firmware, rooted and safestrap installed. For those who do not want to install safestrap you can skip those steps and update superSU from the playsotre.
** Safestrap will no longer work after updating to OA8. You can access Safestrap by flashing back the NK2 Kernel and then the OA8 Kernel when you are done using Safestrap.**

I believe to root you have to flash the whole ncg Odin tar itself, not just the kernel. See #5 in the "notes" at the bottom of the original post of this thread. While this thread is about updating to lollipop, to first get root the part in the notes is applicable. Flashing just the kernel gets you nowhere if you don't have root yet and safestrap installed.
What firmware are you currently on, 4.4.2, 4.4.4, or lollipop?

[Q] Just got a new S5... and it has OA8 preinstalled on it. And its not rooted.

Hi all,
Just got my fiance A Verizon S5... and it came with OA8. Unrooted. I've been on T-mobile since the G1 and have had pretty much every android phone with custom roms since then.
Just a quick question, what would be the fastest method to get this thing rooted? Should I downgrade, and if so to what verizon, root it, then use the keep root methods? I dont think I can find a way to Root OA8 directly, and I'm not sure WHAT version to downgrade to, to get root with, then to keep root on the Oa8.
Any Suggestions?

Flash the NK2 retail tar from here to downgrade (using Odin included in this same thread's root zip). You'll load the file in the AP slot of Odin, press Power+Home+Volume Down while starting your phone. Press Start.
Then just follow the instructions to root.

Just follow the guide linked below.....except since you are on Lollipop, Load the NK2 Stock ROM in AP slot, flash it, and boot up normal before moving onto Step #3.

Oh... forgot that after the NK2, you'll have to boot back into download mode on your phone and flash the NCG kernel only (included in the package), since safestrap doesn't work with NK2's kernel.

Hmm... any step by step?

Coming from Stock (UNROOTED) OA8:
Check here for downloads: [SOFTWARE GUIDE]***Odin Back To Stock***[Root Files] Retail Verizon S5 Firmware Files
1-Download ROM.zip, TowelRoot.apk and Safestrap.apk and put it on an External Storage
2-Put phone in download mode by holding volume_down + power + home_key
3-Put NK2 Full Stock TAR [G900VVRU1ANK2_G900VVZW1ANK2_G900VVRU1ANK2_HOME.tar] in AP Slot in ODIN and flash it
4-Put phone in download mode holding volume_down + power + home_key
5-Once phone boots into stock NK2, go back to download mode, put NCG Kernel [NCG Kernel Only] in AP Slot in ODIN and press Start
6-Once it boots, install and run TowelRoot.apk [Towelroot] and make it rain! Then install Busybox (I use Busybox Installer) from the play store and then install Safestrap.apk [Safestrap Recovery v3.75] and once installed open it and Install Recovery. Some have had to repeat the Busybox and SU install before it will ask to update SU and disable knox.
7-At this point you should be able to boot into SS Recovery and make a backup and do an advanced wipe of everything but your SD card
8-Flash ROM.zip of your choice to stock slot, press HOME and if you are using an Android 5 ROM REBOOT and select DOWNLOAD MODE
9-If it is a rom later than NK2, flash the appropriate Kernel for your device and Android version in AP Slot (PDA) in ODIN (AGAIN, DEODEX VERSION WILL TAKE UPWARDS OF 10-30 MINUTES ON FIRST BOOT ONLY)
For Android 5 ROMS, although Safestrap is still installed, you will have to flash NK2 kernel, do what you need to in SS and reboot to download mode, flash the Android 5 kernel and reboot the system.

i find the fasted method of rooting any device to be:
1) go to the general section
2) look at the stickies
3) click the one that says ROOT

[How-To] Update to G900P_OD3-5.0 and KeepRoot w/Knox(0x0)

**You can begin the following process from any Build/ROM but you must already have Root Access**
**Required** FlashFire - Play BETA - PREVIEW

2. Sign up to receive the BETA versions from Play Here.
- Use the link provided after sign-up to download the app.
Downloads:
- G900P_OD3_Stock_Rooted_ROM
Set your screen timeout setting to 10 mins before beginning!
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 G900P_OA6_Bootloader using Odin's PDA/AP slot.
*If you are already on the OA6 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 Sprint splash screen for about 1 - 2 minutes before completely rebooting. Done!
Tip: for blazing fast speed turn off animations from Developer Options and reboot!
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 to OD3. The ROM will not update your bootloader to OD3 in order to allow downgrading to previous firmware versions.
3. No need to wipe prior to flashing! The ROM will automatically perform a factory data reset.
4. If you do not already have root access (or to unbrick) you must flash the NE5 full Odin .tar using Odin's PDA/AP slot and root with TowelRoot, before continuing with the above process.

3. No need to wipe prior to flashing! The ROM will automatically perform a factory data reset.
4. If you are currently unrooted and on a non-"Towelroot-able" firmware version you must a)downgrade to NE5 using Odin, b)root using Towelroot then proceed with the above process.

Hi, I'm current at OD3 stock and sim locked. I just wanna ask, if I do this, will I be able to downgrade to 4.4.2 and unlock sim using SSU? Thanks.

Since the ROM will not flash the OD3 bootloader you will be able to downgrade back to 4.4.2, however you will need to Odin flash the OA6 bootloader in order for the ROM to boot. As for sim unlock, I know nothing about how that works on this device.

Okay, can you check if I understood the process correctly?
1. I'm in stock OD3, not rooted so I need to root my device first. (Is root necessary? and do you know how to root OD3?)
2. Get flashfire app.
3. Copy G900P_OD3_Stock_Rooted_ROM to storage.
4. Flash using flashfire app.
5. Flash G900P_OA6_Bootloader using ODIN.
6. I can now downgrade to stock NE5 using ODIN. (can I use the one from sammobile.com?)
Can you check if I understood the process correctly? Thanks.

The point of this process is to keep knox (0x0). Twrp will trip the warranty bit so use towelroot. If you do not know what root is I suggest that you first do alot of reading before flashing anything.

Okay. Let me just clarify if I understood this.
The things that I need:
1. Flashfire
2. G900P_OD3_Stock_Rooted_ROM.zip

4. SM-G900P_NE5.tar
Process:
1. Flash G900P_OD3_Stock_Rooted_ROM.zip in flashfire.
2. Flash SM-G900P_NE5 .tar in ODIN. What will happen after I boot this?
3. Towelroot
4. G900P_OA6_Bootloader.tar.md5 in ODIN.
Can you check if I understood it right? Thanks.

Success but I have a question....
I successfully updated to 0d3 using this method. I was wondering if it is possible for me to downgrade if needed to 0A6? I .am rooted using odin and superuser.
Thanks in advance

Rooting Tools For Lollipop​Edit: I reuploaded the Rooting_Tools_For_S5_Lollipop.zip as the md5 was not right if your md5 is not b3dc378a34c0551efe4925912bfa1a9c please redownload and delete the .1Stock_Firmware_Zip from your internal and external sd card and reflash zip
Here is every thing you need to use safestrap without odin. This zip will install the files need if you have to return to KitKat NCG to obtain root. It will also install the firmwares that can be flashed in safestrap so you will not need to use odin. This zip will also install Lollipop SafeStrap Recovery which will allow you to use safestrap without having to use odin to flash kernels and firmwares. I recommend using safestrap to flash for the simple fact if something goes wrong you can still have a chance of booting back to safestrap to reflash something as where using Flashfire if something fails there is a good chance you will have to odin back and start all over. For you who prefer Flashfire I still recommend installing safestrap just as a backup just incase flashfire fails. This zip will also install the Flashfire app

It will open Safestrap App wait for the SuperUser Request and grant permission(This may take a few seconds be patient) once you grant permission you may have to go back and reopen the app. Then install SafeStrap. wait for safestrap to install then click install safestrap again(Sometimes on BOD5 firmware it takes 2 times to stick this is why I say do it twice)
4. Open Lollipop SafeStrap Recovery
5. Click on Recovery Reboot
6. Click The Flash Button Grant SuperSu Root Access
7. Click the Reboot To SafeStrap Box
8. Phone will Reboot to SafeStrap. (If for some chance it doesnt boot to safestrap you will need to use odin and manually flash one of the lollipop kernels below. Then once rom is rebooted install safestrap again and problem should be fixed)
9. To return to rom from Safestrap you will need to flash the the stock kernel matching your rom or if your flashing Firmware then just flash that zip there is no need to flash kernel if you flashed a firmware zip. The Firmwares only need to be flashed if the rom you flashed is a different firmware otherwise just flash the kernel. The Firmwares will be located on internal and external SD cards in a file called 1Stock_Firmware_Zip folder and the Kernels will be in 1Stock_Kernel_Zip folder They should be at the top of the list of folders
10. If a problem happens when flashing a rom and you bootloop you will then need to use odin to flash the NI2 Kernel then you can get back to Safestrap

Did you unzip and load the md5 tar in odin? Are you on BOE1 firmware if so you can not flash older firmwares.

Yes, I just did this two or three days ago from stock oc4 in order to install AllianceROM. Follow the instruction in the first spoiler and it works like a breeze. All you need is an internet connection for towelroot.
Edit: I was trying to reply to a post in discussion but it won't quote the post, and I have too few posts to reply there

long time lurker, first time poster. All boils down, nothing works, especially with locked bootloader.
I stupidly took OG5 OTA update, now I lost my root and that also locked my unlocked bootloader! I had tried everything that I could find on this form and google, NOTHING. I even ran Linux on VM and created custom ROM to work with OG5, nada. It didn't work.
I ODIN'd my phone back to the OG5 OTA update.
Until someone finds the way, I am stuck with extremely bloated stock which I hate so much.

@jrkruse, I'm a little unclear on something here. Maybe I'm just dense, just ask my wife.?
I'm currently on rooted stock NK2, with SafeStrap, and if I understand correctly I need to flash the OG5 room, and the OG5 kernel. Since I'm already rooted, I don't need to run the RootTools zip, correct? Also, what about the bootloader? Did I miss something somewhere?
