G900A-OC4 Downgrade and root available or not??? - AT&T Samsung Galaxy S 5

I read that a Samsung S5 G900A that took the OTA update could be downgraded and then rooted, yet I can't find that information on this website and don't really trust others. This info was specific to the G900A-OC4, not the G900F or others. Is it possible or not?
EDIT: There's even a service on eBay offering a remote IMEI repair where downgrading from 5.0 on a G900A is $10 extra. Mentioning this because they obviously have to downgrade and root to do that, and if they're able to downgrade 5.0 OC4 why can't the rest of us?

Probably because they are lying. Who though, they might have found a way and are just charging for it, as far as we know though, it is not possible to downgrade from the 5.0 ota unless you updated through flashfire.

If you used muniz_ri's method and flashed the rooted oc4, it should have came with an old bootloader so just downgrade to nce and it should work.

Easiest way is to just check what version rom you are using. Unless you are using custom rom, it'll either be MLG for leaked version Kitkat or NC2 which is the official latest Kitkat. I think the OP was talking about the leaked version Kitkat which has the old (better) bootloader.
The latest NC2 has updated bootloader which make it impossible to downgrade or root.
If you are still on MLG and never updated your bootloader (by installing NC2), then you should be able to go back to MJ5 JellyBean. Everyone or most of us on official NC2 is stuck with this version and regretting taking the OTA update.

I have the AT&T S5 running Lollipop.
I don't recall - but I *think* I got this device before Lollipop was released. I got the device in May'14. My research shows that Lollipop came out Nov'14.
So - if I got the device with the prior release - but it's running Lollipop now - is there a way to root it?
Thanks.
No I have the same problem. I have been waiting for months now

If you took the lollipop OTA then no, there is still no active root available.
Any news on root yet?

If you are on the official 5.0+ ota, through any means other than the prerooted flashfire method, there is no known way to downgrade, root, etc. If you flashed the ota for lollipop, bought your phone and it had lollipop, or took the ota, and it is an att s5 (G900A) then it is not, at the time of me posting this, possible to downgrade to KitKat or root or anything of the sort.

Does anyone have the firmware for the lollipop on s5 active?
Does anyone know if models of S5 being sold as new now are being released with lollipop or kitkat preinstalled?
Is there a way to know by serial number on the box?
The reason I am asking is I just purchased one online a few days ago on the daily steals website has it was advertised As new and unlocked. I did not realize being that I am from Canada that this was a lockdown AT&T model. It is scheduled to arrive in the next day or so and I would prefer not to open the box and affect my ability to return it without restocking fee if it already comes with lollipop on it. Hi I'm less concerned about achieving root and more concerned about having the ability to native flea tether on my plan back here in Canada.
Also if it did come with lollipop firmware preinstalled, is there a way to enable native tethering on the phone if root is not achievable?

I'm not aware of any way of knowing before hand.

I'm not sure either I would just see if it is a 5.0 and below and just achieve root its so simple then you flash native tethering it just sounds like that would be the easiest way
5.0 and below or just kit Kat?

Not getting my hopes up, but hopefully with 6.0 there will be an exploit.

KitKat 4.4.2, if you're on 4.4.4 you can downgrade, any higher (5.0) and you're stuck.

Downgrade to 5.0.1?

This 5.1.1 is ****. Any way to downgrade?
Very sluggish and unstable.
Sent from my SAMSUNG-SM-G900A using Tapatalk
I am still at 5.0 and I think I have corupted data files and need to do a total wip with a new firmware. If 5.1.1 is not good can some one tell me which firmware to get and how to get it? Also maybe a link on how to update it, I am no longer on the att network and I need my phone asap. Thanks a million.
AT&T Samsung-sm-G900A
So is it fairly accurate to assume that if I have an AT&T Samsung-sm-G900A with 5.1.1 update from AT&T I cannot root the phone because I can't downgrade the rom to a lower version that will allow me to root?

right,
I'm hoping though that 5.1.1 to 5.0.1 is still possible.

Root for S7 found. S6...?

So a thread on Reddit pointed to a thread on XDA claiming root has been achieved on the AT&T S7 via a leaked engineering bootloader.
The same was done with the T-Mobile S6 a while back. Anyone know how/where these leaks are coming from? Can we start a bounty for the same for our 920A? I'd consider chipping in...

Just out of curiosity on your rooted s6 edge. Are you on 5.0.1 and never got 5.1.1 and that is how you have root? I'm frustrated my s6 came with 5.1.1 and can't get root. I found a video that claimed to have root for 6.0.1 on att. So I grabbed the oj9, pd5 and pd6 and adb and sideloaded to 6.0.1. Then I tried that root, I found, which bricked my phone. I have since recovered back to oj7, thanks to the awesomeness which is XDA. Thanks in advance for your reply.

So for some background: I purchased the phone on release date so it came with OCE. Since I expected the phone to be difficult to root, I was careful when updating and only updated as far as OE2. As far as I know, that was the last version able to be rooted via Ping Pong. One of the reasons I purchased the phone was the ability to use Samsung Pay and I was tempted to update to 5.1.1 with Metalcated's method for rooting 5.1.1 but as I use the fingerprint scanner, the possible issues with it were a no go for me. I've been ever vigilant for possible ways to root, but nothing has seemed too promising.
TL;DR
I am rooted on OE2 via Ping Pong and haven't updated since then since I'm waiting for a full root.

Highest version successfully rooted?

Hello all, I picked up an N900A for a great price, didn't know about the locked bootloader, I assumed it would be the same as the T-Mobile one I used to have. No dice. I'd just like to know what the latest version is that can be rooted.
I don't need custom ROMs or any of that jazz...I always end up modding the crap out of them and changing everything so it's pointless for me to flash somebody else's preferences and tweaks I probably won't agree with anyway. I just need root, SuperSU, busybox, and xposed support.
Right now I'm on NC2 4.4.2 which is decent but I need Lollipop to run some apps I use. A few of them don't support Kitkat anymore.
Any advice would be appreciated

I'd like to know how to root as well. My n900a is on 5.0 and I've seen nothing but bad news on these forums...

You can root 5.0, but it has to be either a pre-rooted 5.0 Rom or you have to downgrade to Kitkat, then root and install 5.0. But you can't root if your already on 5.0.
