[Q] Flashing Back to Stock Assistance Please?

Hey guys,
I purchased the Galaxy S5 back in April and now I am selling it so that I can purchase the LG G3. The problem is I'm trying to flash back to stock with Odin and it won't work. I downloaded the stock firmware from Sammobile and loaded it into Odin, put my phone in download mode and hit start and it says "fail." I can't get it to flash. I'm rooted but I haven't installed a recovery or custom rom. Any guidance would really help. I have no idea why I'm getting fail errors.

I'm rooted but I haven't installed a recovery or custom rom. I used the Supersu update by chainfire to disable knox. I remember on previous Galaxy S versions that if you took the OTA update it prevented you from flashing custom roms of flashing back to stock. But I haven't taken an OTA update or anything so I can't figure out why it keeps saying fail? Do you think I need to re-enable knox? If so, can I do that in Supersu? Or is there another problem? Any guidance would really help.

How to root the Samsung Galaxy S5 Active on the NG3 update

A new update is being released for the S5 Active, since i didn't see a thread on how to root the device... Here it is...
Towel root works on the NE4 build but will not work on the new NG3 update.
So what i did was downgraded with the firmware file found on Sammobile with the NE4 build.
Then used Towel root and installed SuperSU, it said it failed to install Supersu but after a reboot all was well.
Oh this was a AT&T S5 active.
SuperSU worked fine and root was verified!
I haven't posted much before. I would like to give back to the awesome community who has done so much for me!
Hit the thanks button if i helped!

Could really use your help

Trying to use your same method
I am trying to root my phone with Towel root and it won't recognize my phone either. My phone deleted all it's text messages, for some reason, last night and I need to root my phone so I can save some of the messages. Came across your post and figured you can help me. I downloaded the may version of the sm-g870A and odin. Odin won't open. I've never done this before and could use your help. If I can downgrade my firmware, or change it, in a way where Towel root would recognize my phone that would be exactly what I need. Also tried all the Modstrings, did no good. Whatever you could say to help, can hit me up personally and help me, idk if you could do that, but it'd be awesome if you could help me.

NE4 and NG3 are official kernel images...
Downgrade consists of flashing the NE4 kernel image via Odin...then rooting the device....and then flashing the NG3 kernel via Odin which will give you a fully rooted rom that is the latest version...
Knox will NOT trip if you follow the thread instructions...
We are forced to downgrade the kernel to gain root due to the exploit being patched in the latest update...
The root method works perfectly....g

Thank you for your help

Lol. That is not what I'm asking. what I'm asking for is what firmware do I need to step backwards to kit Kat. I know if I can get it on revision 2 bootloader lollipop, I can downgrade to revision one kit Kat. I did this in the past but I forgot how. Right now I downgraded to 5.0 and I'm trying kingroot and Kingo root. It's not working

Find the latest 4.4.4 Kitkat version and try.

I did. Says fuse binary of 2. That's why I need the lp firmware with the binary of 1. So that I can downgrade to 4.4. Believe me I know what I'm doing, I just can't find the appropriate firmware. I need the boc 5 firmware. But that was an OTA I think

Need help with root on S5 (AT&T)

I am having trouble rooting my S5 (SM-G900A) . I tried using the Towelroot method with the different codes, it always said that the phone is currently not supported. Since I really don't know that much about rooting, it would reaally be helpful for me to have an easy-to-understand explanaition on how to get this thing rooted.

Root S5 At&T
Hi, I have the same problem, I have an S5 from ATT with lollipop 5.0, I tried to root it and now is showing me a notification that says that I have to take the phone to an ATT center to undo whatever was done, but no root, if you had any help with this topic please letme know, thank you

If you have lollipop installed, there is no root method and no way to downgrade. Boot loader is locked down like fort Knox as well. Not many devs use this 2 year old phone anymore.

super duper easy root

You can't flash back. If you have taken the 5.0 or later update, THERE IS NO POSSIBLE WAY TO ROOT OR DOWNGRADE CURRENTLY.

ah he didnt specify that he took an OTA update to 5.0. thanks for the clarification

I have Android 4.4.2 installed, but Towelroot still does not work. I bought the phone back in the USA, then unlocked it and took it to Germany two years ago. For this reason I can't get any newer Android versions.....

also which towel root version did you use v3 is the easiest it doesn't require Internet access.

Same problem here. Got a code-unlocked AT&T S5 on T-mobile SIM running 4.4.2. Kernel is from July, so Towel root doesn't work.
AP: G900AUCU2ANG3

I want to do the following:
1- Root the phone without loosing the unlock
2- Update to Android 5
3- Replace the OS by unbranded android, ideally also get rid of the samsung bloatware as well.
Is it possible? I Spend 8 hours already looking for answers, but none f them apply to my specs.
Many thanks

Unlocked is unlocked. You can't lose that by flashing.

You can't do the OTA update anymore because its not available anymore. But you could download the OTA update file and sideload it.

1. Yes, you don't need the OTA because you are already on NG3 so just start from step 2.

It works! Thanks so much. Now I have a rooted Samsung Galaxy S5 on running Android 4.4.2. Baseband G900AUCU2ANG3. Phone was originally from AT&T, unlocked and rooted, currently being used on T-Mobile.
1- How do I upgrade to a current Android version?
2- How can I remove all AT&T bloatware and have an unbranded phone?
Thanks.
