AT&T Galaxy S5 Active downgrade? - AT&T Samsung Galaxy S 5

I know it's been asked previously, but not recently as far as could see. I have an AT&T Galaxy S5 Active SM-G870A with Lollipop 5.0 OF3 on it and I would* love* to roll it back to KitKat. Being an S5 Active, it already has connectivity/network issues, and then Lollipop on top of this has made the phone so unreliable that I've simply moved back to my Lumia 640 and put the S5 on the shelf. Failure to load webpages because it simply "lost" connectivity, constant data switching, and not able to get a call in or out randomly with even an apparently good signal. I like the phone a lot, but I like consistency and reliability much more.
So, as of yet, is there still no way of downgrading from OF3? If there is, I am all ears!
P.S. This device was never rooted and the 5.0 update came OTA
Thanks!

No this can't be done and I don't think anyone is trying anymore.

So am i better off installing the 5.1.1 update and giving up hope that downgrading will ever be possible? Does the updates fix connection problems, or is my phone's hardware just defective? I literally cannot load two consecutive webpages right now over the data connection. With Wifi there is no problems. Right now I can't even get an SMS to send. Mind you this is happening in all of the same exact locations in which my Lumia has no problems.

@x_orange90_x I've had no problems with mine. Perhaps this will help.

No. If you have 5.0 you can't downgrade. This is talking about downgrading from 4.4.4 to 4.4.2 back in 2014. It's just not possible.

Android 5.1.1 OTA being rolled out on T-Mobile for the S6 edge!

RELEVANT TO US BECAUSE WHEN WE GET THE UPDATE, IT LOCKS THE BOOTLOADER.
IF THEY LOCK IT FOR THE S6 EDGE, THEY'LL LOCK IT FOR THE S6!
DO NOT TAKE THE OTA IF YOU DON'T WANT A LOCKED BOOTLOADER.
Unassuming Galaxy S6 edge users are in for a surprise, as T-Mobile appears to be rolling out a freshly cooked OTA based on Android version 5.1.1 Lollipop for the device. The catch, however, it is so far reported only on the T-Mobile network.
XDA forums user Sunderwear mentioned about the OTA a couple of hours back (at the time of writing this story). Urged by other users of the device, the poster also uploaded a video of his Galaxy S6 edge running the latest firmware. The video can be found at the end of this article.
As noted from the narration, the update also locks the bootloader on the device.
So, how many of you have already received the update? What do you think of it?
Source: http://www.sammobile.com/2015/04/29/android-5-1-1-ota-being-rolled-out-on-t-mobile-for-the-s6-edge/
Looks like someone in the Edge forum was able to downgrade the bootloader and flash TWRP but still, tread carefully.

ok I downgraded the Bootloader ONLY and I was able to flash TWRP...dumping a system.img copy..

Coming from the ROM Flashing mecca of HTC and finding a place in Samsung is.. weird to say the least. I find that there are only minor things I need that require root but I no-longer need the overhaul that I needed with HTC. It's too weird.

If/when anyone gets this update try to grab the update before taking it. Also, the bootloader Doesn't actually get locked.

Isn't it odd that just one guy has gotten the update? T-mobile has sold hundreds of thousands of these units and only one guy got an OTA?
I'll believe it when I see it.
Is it possible to do the update if we are rooted? And I mean UPDATE not flash the entire new release.

This type of thing might happen with a lot of updates. You need to remember the rooting/moding community is very small compared to the people who just use their phone as is. So if anything I think its weird that someone in this community got the update.
Hey I hope it's true, I for one hope it fixes the memory management and battery issues.
According to this guy, it looks like the XDA member was part of a "Soak Test", or he is a guinea pig. Hopefully it doesn't take months to test it.

Damn I wish this would leak for AT&T. 5.0.1 TW has a bigger memory leak than stock 5.0.1 on my Nexus. This needs to be rolled out ASAP, but I know it won't.

Lags and stutters on my Note 4 after Lollipop

My N4 is from Singapore and I updated it to Lollipop 5.0.1 due to OTA update that was always in my face. Since then, the phone experiences lags and stutters a lot to the point where it will be unresponsive for 5 seconds and above.
also, i have very terrible data connection. sometimes the data arrows move but my app does not load. chrome also lags and hangs intermittently.
i have reformatted and cleared cache via recovery. any ideas what i can do to help fix the phone? I am running stock unrooted Note 4. any help will be greatly appreciated.
p.s. I prefer not to root at this point as I want to be able to keep my warranty status intact. Plus xposed on lollipop doesnt seem to have much apps for me so sticking to stock unrooted.
I've been having this problem too, tried custom ROMs and tweaks, things improved but not that much

I decide that I will not update my Note 4 any more ........... unless one day .......... there will be a better stable firmware.
I don't care about Lollipop .............. Lollipop is the most faulty Android version ............ keep away from Lollipop
Maybe we should wait for Android M in 2016

Same here! I brought the phone in for service and hoping it will magically come back with 5.1.1 fixing all these stupid bugs. Dont know why did Samsung ruin the perfect N910G! Sigh.

I know what you mean man. I took the adivce of everyone here and rolled it back to kitkat 4.4.4
will test out and see how that goes. otherwise i will let go of it and use the oneplus till note 5/next phone gets released.
ive never had any stutterings or lags whatsoever..im stock
I tried package disabler (yes, I know it costs money), disabled around 40 (non-essential) packages and my note is as smooth as when I first bought it on KitKat.

Nope, seems to be yet another placebo fix.
Same for my N916S, the stutters and delays annoy me so much, hard to believe it's a stock rom, it probably happens to S5 5.0 as well
But unfortunately, no kitkat for me, my variant is shipped with lollipop out of the box, sign
Factory reset always helps after an OTA update. I had N910F, the European version snapdragon and just few weeks ago replaced it with N910C, UAE version which has exynos chips. I find N910C lags way less. Infact, no lag at all. It came with lollipop installed then I flashed stock Poland firmware as they had the latest.
Everything is working great! Using Google launcher. Hate Samsung's folders and I find Google now one swipe away much more convenient.

AT&T Galaxy S6 OTA upgrade 3/3/2016

Anyone else receive this OTA this morning? I didn't see, or look for, a detailed change log before proceeding with the OTA push. Phone rebooted and is optimizing apps right now. I'll provide further details once it finishes.
I know, for sure, that I checked for new software within the past week or so and there was nothing available. I've been up to date with OTA upgrades since getting this phone on day one of its release.
Anyone know anything about this upgrade?
Model number: SAMSUNG-SM-G920A
Android version: 5.1.1
Android security patch level: 2016-02-01
Baseband version: G920AUCU3B0J9

-_- security patch, not marshmallow
Edit: ATT site says device security and performance updates
Bastards
thanks for the heads up. Downloading now.
I installed it and really don't notice much of a difference. I guess this means no M for another 2 months at this point.

Probably just updating security mostly since we were a few months behind. Could also be preparing our phones to take take 6.0 update since there's usually a small update before a big one. Wouldn't hold my breath on it though

Don't try to apply this update if you've applied one of the leaked insecure boot images (for getting a root prompt). There's a check of the boot image built into the updater and if you attempt installation it will wipe your phone back to stock.
D**k move Samsung, d***k move.
I was a fool to initially think that the update juuuuuust might be Marshmallow. And then I thought, "I have AT&T. They would've made the announcement before just releasing the OTA. Hell, they would've made a big deal out of it, even; as if they're doing us a favor. " And so, I took a Valium and went to sleep.
This update seems to break mms for many of the users myself included verified with AT&T that is indeed related to it Samsung is on process of updating. Anyway if you happen to get it just boot your phone to safe mode and then use mms there and restart back to normal, it works after . And hopefully marshmallow will be soon

I'm still getting MMS texts, what was broken?
So far I've noticed my battery life is better than it was before, on the OJ7 update i had a very odd drain as well as issues with my bluetooth and wifi that were only fixed with a reboot......so far knock on wood they seem to be resolved but it should take a few more days to fully confirm. I did also try Enhanced LTE again and just as before I had a nice drain on my battery so they still don't have that working great yet (my area has weak LTE and switches between LTE and 4G on a normal basis).

Update Available 895MB

My AT&T Galaxy S5 (Lollipop) says there is an "update available, connect to wifi". Its 895MB so I'm assuming its MM.
Any problems going to MM from Lollipop ? How can I find if all my apps are compatible with MM ?
I just turned on wifi and it started to download. I turned off wifi for now so it stopped.
Have they addressed most of the bugs with MM ?
These may be dumb questions, but I hate to change things when they are going good as they are...

here is ifo on update log : https://www.att.com/devicehowto/tut...tep_KB424848?make=Samsung&model=GalaxyS5G900A
After seeing the update availability on Sunday night (8/28), my wife and I downloaded and updated both of our S5s with the 895mb file from AT&T. Downloads took a little over an hour and updates about 20 minutes. No obvious problems and both phones seem as or more stable than with 5.1.1. Battery usage seems dramatically improved as well. We've each run through most of our favorite apps and nothing seems amiss.
Getting reading to change our SD cards to adoptable (internal storage) tonight. Hopefully that goes well.

No problems and although some people are saying battery life is unchanged from 5.1.1, that is definitely not the experience I'm having. My use is fairly consistent from day-to-day and I find i have about 20% more battery life left at the end of the day. However, I do no gaming of any kind and video is generally limited to youtube technical stuff and an occasional movie trailer.
Again, the experience is certainly not less than before the upgrade.
One disappointment however. Samsung does not support using the SD as an internal device, even though the OS does.
I'm now looking into rooting the device, but it seems a little early since MM was just released.

Thanks for the update.
So the phone does not see the SD card anymore with MM ?
I thought the AT&T version couldn't be rooted because the bootloader is locked..

I can see the SD card just like before, but one of the features of MM is to allow the SD card to be treated as internal storage so that apps can be loaded there. Unfortunately, Samsung has somehow caused this to be disabled on their devices (even on the S7 with MM). Rooting would be the only way past that as far as I know.
I believe there are instructions here on xda to root an AT&T S5, but only with KitKat at this point.

Since I use a MiFi for connectivity, I've never used the Mobile Hot Spot and don't have it on my plan.
I did check my phone for availability, however, and it's right there in Network settings. If I attempt to turn it on it just tells me I need to go to AT&T to get a plan. If you have a plan it should work.

Can I go back?

I am interested in rooting my Samsung S6. I have been curious about the process on Android phones for a while. I am currently experimenting with Android development and would like to learn as much about the concepts as possible. My questions are; if you root a device as mine can you later go back to their (AT&T, Samsung) factory setup? I mean like what the phone came new from AT&T? Is there a way to back this state up so I can return to it? Any suggestions or information is cool. Thanks

ODIN back to Stock is how you get back to original.
Now the bad news. The ATT S6 cannot be rooted unless it has very old firmware on it. I think it was back in the 5.0.x days.
I never rooted it so I cannot remember for sure.

That's cool; it is good to know this stuff before trying to do what is impossible. I have an S5 I could try, or I will just acquire a model that is good for rooting. I am interested in the concepts here, not so much fixing anything with my device (although that would be cool also). Could you recommend one? Why when using a program that backs up the Android (BackupTrans WhatsApp Backup) did I get a message that says "You need to root this phone"? Then it gave me steps showing how to do it. Are they just not aware of the limitations of this model (S6 AT&T)? Thanks

Are they just not aware of the limitations of this model (S6 AT&T)? Thanks

I do not know about the S5. The ATT S3 is still getting updates and is rootable. They have Nougat firmware they are developing.
Most likely the software did not have something right. There are several versions of the S6, but the ATT version has a locked bootloader now.

I am imagining that there must be a way (website or something) to plug in some numbers from the back of it, to figure out what version you have? I mean something that lets you know what's possible? Thanks

First simple check is in Settings-About Device
If it states Model Number is SAMSUNG-SM-G920A it is the ATT version.
Also, on the back of mine there is a label near the bottom. It is hard to read (faint), but it also states SM-G920A
Check those first.
