need to revert to 5.0 or 5.0.1 not sure how

I am currently on 5.1 but work for at&t. I just put my work email on my phone that also requires a monitoring service called mobile iron that monitors my phone. My company now thinks my phone i rooted because I have "prerelease" software on my phone and am in danger of getting in some pretty serious trouble. I talked it over with my manager and they're giving me time to fix it, but I need to get off 5.1 as fast as possible.
I can't root and I can't unlock bootloader but I need to get off 5.1.... can i just flash a 5.0.1 ota zip? Really not sure what to do but don't want my company phone taken from me. all my clients know this number.
Thanks in advance

I think the only way to downgrade the version is to flash through the bootloader or flash a custom rom but you can't do either, but 5.1 is officially out so its no longer pre release software.

You have to unlock the bootloader to flash anything. No you cannot flash an older ota (ota patch existing files to new versions, not replace entire files) and as mentioned l, 5.1 is not pre-release.
How did you get 5.1 in the first place?

At&t hasn't approved the software I guess, so by their standards it's considered prerelease. I honestly don't see why it's even an issue, we use the exact same images that gpe versions get so it shouldn't matter. Not sure what to do at this point.

I just installed it as an update.zip using adb. No unlock required.

FYI, AT&T have no control over the update process. The update comes directly from Google, for all carriers. As long as you didn't install M or I, you're fine. There is nothing that AT&T could do to prevent anyone getting the update. Except maybe sending a memo out to a staff saying "you'll receive an update from Google. Please, please, please don't accept it"

Can't you root and go back to 5.0 and relock bootloader and reinstall the mobile iron app?

Doesn't need root. He could unlock the bootloader, willing the device and then flash the system.img and ROM.img for a 5.0 ROM. Then relock
But its pointless. 5.1 has been released to both versions on the nexus 6. The north American one and the international one. AT&T do not.control updates going to their "branded" nexus 6 device. They're coming from Google directly.
Edit..
Hmm maybe I'm wrong...

Maybe like tmo, Google will be releasing a different 5.1 for at&t. This is disappointing news for nexus devices.
So yeah, unlock BL and flash system.img and boot.img from 5.0

Its not a different 5.1, but they delay the updates. As soon as the update is apppved it won't be considered "prerelease" and everything will be fine. It's a complete formality. But, it is what it is. I guess I'm going to just pull my email off my device and hope the "trackability" breaks. Not willing to risk boot loader unlock as I'll have to give the device back at some point. Again, as long as I don't put any "at-risk" firmware on the device and relock it shouldn't make any difference, but it does.
*sigh*

You can unlock the bootloader and relock it (so long as you check it boots first). There isn't a flag or trip or anything that they will see.,

Oh, I was thinking the boot loader status would show "relocked" when in fastboot

How to update my AT&T S5 G900A to 5.0 from 4.4.4

Not rooted or anything. I cant seem to receive any OTA from AT&T. Tried Samsung kies at it says my phone is on latest firmware, even though its only on kitkat 4.4.4
I found a solution by quick googling. I'm just wondering if this is advisable and wouldn't void my warranty.
http://www.droidviews.com/install-rooted-lollipop-on-att-galaxy-s5-sm-g900a/
Note: it does say install "rooted" lollipop on the link, but it was only optional. Seems pretty shady to me. I just don't want to flash anything unsafe that will mess up my device.
Is this reliable or is there another way? Not planning to root/void my warranty atm.

You could root and go to 5.0 and never use a root application. You could also unroot your phone using the app that prompts access to administer those privleges. Technically you would void your warranty but you can always downgrade back to Official 4.4.2 for any reason (sadly you can't root 4.4.4). Just a suggestion, my friend. ?

Root and upgrade out of country G900A

I'm not very hacky or what you call it, my know-how in this region is not very good, so I'm hoping someone here is able to help me.
When I was in USA I bought myself a AT&T Samsung Galaxy S5 (G900A), paid it off and had it service unlocked (called AT&T and they unlocked it for me). Then I went back to Ukraine and now I want to to be rooted... and have lollipop.
I don't know how to upgrade it to lollipop... Kies and the phone says I have the latest firmware and I cant get it updated. On top of that, I've read in posts here that if I update before rooting it, I might be in trouble later on the road.
Towelroot V3 says that my phone is not supported so I can't root it that route...
I've read tutorials here about rooting with the ND3 update... first of all, I don't know what the ND3 update is and how to obtain it since I can't update my phone OTA in Ukraine.
How do I go about this?

More information about my phone (since I learned more information about this process).
Kernel date is Tuesday July 22 2014... towelroot is said to work for any before June 3, 2014... this is probably why my phone isn't supported.
Also, is it true that Android 5.0 removes the SD Card functionality???

Well, I got it rooted... thanks to muniz_ri!
I just went ahead and risked it, not knowing what ND3 or NG3 was.
My next step is flashing it to Android 5+ ... that is if it doesn't remove the SD Card functionality

Well, I found these instructions on flashing my G900A to a pre-rooted stock lollipop... the problem I'm having is with FireFlash... I can't seem to find that app anywhere.

Thank you!!!!!

Wait, I'm confused - you say you were able to downgrade your G900A to a rooted 4.x state? I thought root was impossible once you take the 5.0 update?

You can only if you didn't take on the 5.0 OC4 bootloader and kept OA1

I didn't take the 5.0 update since I am out of the country and OTA updates don't come here... but I did have the NG3 update... so I downgraded to ND3, rooted and went back to NG3... then I flashed a prerooted 5.0 stock ROM with OA1 (I think...) and now I'm using it...

Rooting Questions

Hi Experts,
I am plannign on rooting my SM-G925T butu I have a couple of questions before I continue, I have an out of the box version and not updated yet as far as I know, it is currently on 5.0.2. I see a guide to Root but it is for 5.11.
- Is it better to update my phone first before rooting as the guide I saw for rooting without tripping knox is for 5.11.
Thats all my question for today, I may think of something else later though.
Thanks

You can root 5.1.1 without tripping Knox, but that means your fingerprint scanner will be rendered useless.
Personally, I stayed on 5.0.2, rooted with PingPongRoot and flashed a debloated ROM using FlashFire — all with Knox still intact.

If you want to root without tripping knox and have functioning fingerprint reader, stay on 5.0.2 and root using ping pong as stated by above poster

Thank you both for your response, I would stay with 5.0.2 then.

OK guys I have a question that I am not sure is the right thread but I need to SIM unlock my phone. The only ways currently out needs the phone to be rooted. I have a question of a plan I have and wondering if you guys would know if it works?
I plan to do what you said above and root 5.0.2
Get the phone unlocked.
Then flash the stock rom and get rid of root.
And then upgrade to 5.1.1.
Do you guys happen to know if this will work without messing with my fingerprint reader? Thanks!

It won't, but you may lose the unlock depending what method you use

FYI, this worked completely perfect. Used Ping Pong to root, unlocked and then flashed stock 5.1 and still unlocked

How do I root 5.1.1 DOI1 without tripping knox? I'm aware Samsung pay and fprint scanner are gone but I have a question.....If I decide to unroot and flash back to stock (with knocks untripped, hopefully) is it possible that Samsung pay and fprint scanner should work as a result?

You cannot root 5.1.1 DOI1 without tripping Knox since Samsung updated the bootloader and we don't have an engineering bootloader for it. If you were on 5.1.1 COF6/8, you could still use the engineering bootloader while sacrificing the fingerprint scanner and Samsung Pay. As long as you don't trip Knox or use a custom recovery, you can still use Samsung Pay after flashing back to stock.

So who ever is on 5.1.1 DOI1 non rooted stock(brand new phone) and attempt to flash custom rom ,root phone etc will not be able to revert to stock (like from the box) and will lose SamPay and Fingerprint scanner?
In case we root, we will Tripp Knox and disable Fingerprint scanner?

Can you share what debloated ROM you used? I can't tell how to know if a rom works with FlashFire. I am still on 5.0.2, rooted, but still stock. I would like to try some more roms.

I'm using Looper 2.0. There really aren't that many options for those still on 5.0.2; it seems like the only other one is XtreStoLite. You may have more luck in the Unified Development forums, though I'm not sure if you'll be able to take advantage of T-Mobile specific features (like WiFi calling) on 'universal' ROMs.
I almost forgot to add: it's absolutely essential that you remove the boot.img from any ZIP before flashing or else you'll end up tripping Knox.

I was already looking at XtreStoLite. Do you know if its Aroma installer options work with FlashFire?

Im on this version of 5.1.1. and looking to root. I don't care about knox. I only care about the fingerprint scanner which I am under the impression only gets disabled with that developer bootloader used for not tripping knox. Anyways I flashed a version of TWRP which worked but wouldn't let my phone boot. Itd get stuck on the Samsung screen (not bootloop). I got the recovery is not seandroid enforcing message. I managed to get back to stock after that but Can someone point me into the right direction for which TWRP or CWM I should flash and or kernel after that. I just want to get a rom on this thing. Might as well since ive already tripped Knox.

Basic Q: PingPong Root my AOE2 S6 Edge and flash custom ROM based on 5.1.1?

Hi,
This is a very basic question, but I haven't been able to find the answer in one place.
I have a new Galaxy S6 Edge G925A on AT&T, baseband version G925AUCU1AOE2. I don't want to take the OTA update because apparently then the bootloader will be locked and can't be rolled back. I'd like to root the phone and not lose any features but I'd also like to be able to flash a ROM based on the most current version of Android available (and continue to upgrade in the future). Right now I only know enough about rooting, bootloader, baseband, kernels, custom recovery, ROMs, Android, KNOX, radios, modems, fingerprint scanners, Samsung Pay . . . to be dangerous. Every search I've done over the past couple days seems to teach me something while also confusing me a little bit more.
What I'm wondering is - if I root my AOE2, am I then able to flash a custom ROM based on 5.1.1 (or later) versions of Android without losing any other features (Samsung Pay, fingerprint scanner, etc.) and without locking myself to a certain version of Android? If so, what steps would I have to take (e.g., 1) root, 2) install a custom recovery, 3) flash a later kernel, 4) flash ROM, etc.)? Thanks in advance, and sorry if this question is answered elsewhere already!

So - if I want to have the latest version of Android possible on this phone does that mean I can't also be rooted (or be using a custom ROM)?

Correct. Since you are still on OE2, your choices are as follows:
1) root with ping pong and go to
A) custom 5.0.2 ROM, keeping root
B) stock OF3, keeping oe2 bootloader and recovery via odin/flashfire, keeping root
C) stock OF4, keeping oe2 bootloader and recovery via odin/flashfire, keeping root
2) don't root, update to full stock OF3/OF4/5.1.1 (I forget the build number), lose the ability to root, lose the ability to roll back. Possible that this will never be rooted.

Dang. Thanks for confirming. They're sons of *****es. Why do they need both an early contract termination fee AND to lock down the phones so you can't get full enjoyment out of the hardware you're committing to a 2-year contract to get?

My phone is reporting the following
Android Version = 5.1.1
Baseband version = G920AUCU1AOE2
Though my phone has the 5.1.1 update but my baseband didn't get updated does still mean I'm SOL for a future root?
