Keep in mind while this is the official OTA update things can still go wrong that being said remember your g flex must be running stock android 4.4.2 and you must have stock recovery.
Download: https://docs.google.com/file/d/0B5nbznglPEvILTFlWmF5a0J4X3M/edit?usp=docslist_api
Please note once you update you will loose root and you can root again by reinstalling Towelroot if you already have it installed. Make sure you have the latest version of Towelroot in order for it to work.
Instructions:
1-download the above link and place it on the root of your phone storage it will not work if it's not on the root storage.
2- power off your phone and boot into recovery (volume down and power)
3- once in stock recovery select "apply update from sd card" the OTA file you downloaded should be there select it and install it
4- it will take a while to complete and once it's done feel free to reboot your device.
If by any chance you get boot loops then reboot into recovery and wipe cache and then reboot.
That should be all if I missed anything let me know enjoy!!
Update: sorry about the privacy settings on the link I did not realize it was set to private I have hopefully fixed this issue so you guys can start downloading sorry about any inconvenience.

OTA update
Upgraded this AM...Can confirm also that upgrading with this OTA you will lose root. Use IOroot25 to get it back for the Spr version.

Noob question. I am on the 4.4.2 LS995ZV6 version of a GSM unlocked Sprint Flex. My device has just downloaded an update without my consent which. I believe is this. I am rooted by the way. Can I take this the update downloaded on my phone? Will I lose the unlocking status? Will taking the update on a rooted phone create any problems? Please let me know.
I don't think you will be able to properly take the update of your rooted. Also if it does you will lose root and you have to reroot (easy peasy)
If locked. Just look for the guide to sim unlock and delete few stock and (root first) then you will be fine

Hi all.
I had my Z1s rooted and decided to do the upgrade to Kit Kat. Download went well but on reboot it went into Recovery. I chose reboot system which started the phone but made me loose root while not upgrading me.
I downloaded Kit Kat again with the same thing going on and it happened a 3rd time. Upon opening my screen after every attempt I have the error message that the update could not install and that I need to try again.
Not sure what to do now as I have an unrooted 4.3 phone now that is not allowing the update.
Any help will be appreciated.
Thanks,
Doc

OTA update?

Yes, I tried doing it OTA instead of computer.
Also, I have noticed that I have the "fail notice" stuck in notice bar even on reboot.

OTA update will not work if you are rooted and/or have custom recovery.
You can only use pc

Didn't know that. Will do.
Should I re root first or root after update? I have SuperSu Pro which should allow me to keep root on upgrade.

How did you get root on that phone at all? I have z1s C6916 and I can't achieve root if my life depended on it.
What root exploit did you use?
Thanks in advance.

I used the Jcase method posted here in the forum. The main thing is to make sure USB debugging is turned on.

USB Debugging was on. Just wondering also, do you have the Xperia z1s C6916 version? Maybe you have a different version and that's why you were able to achieve root and I am not.

I have the C6916 which T-Mobile sells. Don't know why the method doesn't work for you.
About root, I don't know will root will still remain after update (probably not)
And also don't know if newest one is rootable.
Sent from my C6903 using XDA Free mobile app
From what I have read root can remain using SuperSu Pro. There is also a method of rooting after the update listed here in the forums.
Of course I lost root and it is still 4.4.2, but I can not find any documentation on what changed. Has anyone else received this update?
Baseband version: M8974A-AAAANAZM-2.0.20064
Kernel Version: 3.4.0
Update: TowelRoot does not seem to work with this update!
also got it. its a 220+mb update.
I just got this update as well. I got the message that says it is downloaded and wants to install. I am rooted with TWRP installed now. I have read that some people have had problems and been bricked when they tried to install some updates in the past. For this reason, I went into the hidden menu and disabled OTAs. Guess that didn't work. Has anyone else taken this update being rooted with twrp successfully?
You won't be able to rooted or with custom recovery. Check out the meta-inf script. It will fail if any fishy is going on with your device. I'm going to edit it later tonight so I can post the flash able zip for us to update. All its really updating is the radio.img and a few other apks as well as some security updates.
Checked no update for me. In the Houston area. But read online it was for the VoLTE update and In Flight text messaging

Once we flash and update, towel root will work again? Someone said they couldn't get towel root to work after the update. For now I'm just playing around with cm11. If someone would get it or another ROM working pretty good, I'd just use it. I had planned on selling the flex and use my bump to get a nexus 6 through t-mobile. But if things get rolling a little around here. I'm happy with my flex. I wish there was more I could do but its over my head. My previous two devices were a Nexus and HTC they were easy compared to this.
How do you disable OTA updates?
Sent from my LG-D959 using XDA Premium 4 mobile app
I pulled out all the "abort install if blah blah blah" lines from the Meta-Inf folder and all the lines to install the priv-apps and just for my sake i took out the priv-apps since it would replace with .odex and im deodexed. Checked the updater script for any other "abort or security" crap. Didnt see anything else. So i repacked the update into a flashable.zip and flash away. It adds this really cool "SECURITY ERROR" Under the LG logo on boot up. And transforms the device into a temporary outrageously expensive paper weight.
So i rebooted into twrp and restored. So far a no go. I think after digging through it and seeing what all is in it.....im just gonna make a flashable of the new radio.img incase it upgrades ours and gets better service or picks up those techno tunes from Venus.
I had 2 back to back updates, but I ended with D95920m.
I accidentally downloaded the update. I actually don't even remember doing it. I just saw that it was successfully downloaded. It hasn't updated yet. Is there anything i can do to get rid of it? I don't want to lose root. I don't have a custom recovery installed. I only have root access as that is typically all that I need.
Also, any chance anyone has tried to use towelroot on this after it breaks root? EDIT: Never mind, just saw the OP's update that towelroot will not work. F this. I need to get rid of this phone.
I renamed the file that it downloaded, so at least now it is just asking me to download the update again. I also installed a TWRP in the mean time. I guess I just need to disable updates now.
I am in the same situation... Can you please tell me where the update is downloaded to? I need to rename mine as well in case I were to accidentally hit install update.
How do you get the update notification to go away?
I have seen the option to hide it in one of the xposed modules, but can't remember which one...

I dont have lgdmsclient.apk either. I have the T-mobile (d959) model.
I unexpectedly got a nice surprise this morning with a hefty 400mb update via ATT Update Server OTA. It was 4.4.4, not 5 as hoped but at least it's something.
4.4.4
Baseband: G900AUCU2A01
Kernal: 3.4.0-3116194
Build: KTu84P.G900AUCU2AOA1
The strange thing is after the update, I got an notice that it updated successfully, it said a software update was available again. Downloaded it, and it was almost 500MB but then said there wasn't room to install it. I cleared a bunch of photos and file and then the cache and when I went back, continue update was grayed out. I'm thinking I managed to delete it when I cleared the cache. Wonder if that was Lollipop. Did the date trick and checked update again and said up to date. So who knows, but there was nothing in the FOTA folder.
I called ATT and they were not even aware that it 4.4.4 was being pushed out OTA yet. Said that only 4.4.2 was the most recent, and of course knew nothing about when 5 would be out.
Not worried about it til I can have root on it.
Mine said software is up to date and i'm on 4.4.2. Can someone grab and post update file please so i can sideload by ADB..
I am on 4.4.2
when i checked update it showed getting update, but i was on Data so cancelled it.
Will try in Wifi at home and see how this goes...
Here is the update from ATT website about this update...

Really buggy update and a visual POS!
- The Gallery app has text overflowing if the album has long characters.
- The Emergency Icon was poorly implemented you can see theres an ugly bar next to it and the AT&T logo if you have a passcode.
- When you press the recently opened apps icon the background turns a solid blue instead of showing your background makes it look like Windows 95 or something.
- App drawer lags every time you scroll a page.
So i had to Odin back to 4.4.2 nc build and then Ota to ng then 2nd Ota to this 4.4.4. Whew

I agree with you on the recently opened apps but everything else seems to be working fine for me. Maybe your phone didn't update correctly. Mine actually seems less buggy and quicker. Try a factory reset.

I was rooted on NG originally, but the OTA failed to installed. I Odin flashed to nc build (my phone shipped with NG) so I could install the OTA, but it failed. I redownloaded and tried 3 times. I even tried sideloading the NG update on SD card, but it fails every time too.
Did you have to do anything special to get NG to install? I can't for the life of me get it to work. Or were you originally on NC and in which case I'm screwed?

nope i was on NG - it was rooted like you but unrooting still left the custom logo at boot time. So I downloaded to stock NC - you must not flash the bootloader (BL) file in the 4 files in this rar at http://forum.xda-developers.com/showthread.php?t=2714455 - use the google drive download. You can't downgrade the bootloader. But as long as you don't flash the BL file in odin, flash the other 3 (AP, etc) and u should be good. (if you do flash the BL, no harm, odin will fail, pull battery and restart download mode remove BL from odin).
from there let NC load up and then OTA x 2 (advance date if needed) to the 4.4.4 build.

Hi there. For over 3 monts I keep getting OTA infos about upgrading to lolipop. I'm currently on Kitkat and my phone is being rooted because of the xposed installer + titanium backup and tasker.
As there are gudes on how to ROOT, I don't find any on how to unroot if one has Kitkat version of android.
In order to upgrade via OTA to lolipop one has mentioned I need to unroot phone and uninstall xposed installer as it might alter some files that unrooted phone can't.
So can someone pretty please link me to the guide on how to unroot phone on Kitkat so I can safely upgrade to OTA to lolipol? Thank you in advance and I apologise because I didn't find any explicit guide on how to UN_ROOT.

I did it just like you said. Application closed itself. And I when checking for root it says I'm not rooted. Problem is that when I select download update, it restarts phone and goes to stock recovery mode. Then there is a progress bar about upgrading but I allways receive error and then reboot and after phone boots I receive info about OTA not being successfull.
So my phone is not rooted (At least titnium backup says si). But I still can't OTA to lolipop :S
What are my options here?

Have you tried a factory reset?
Would be a good start to do a factory reset because just unrooting will probably not be enough for installing OTA. You have to revert all changes you did to the system like removing things like adaway (with restoring the original host file), unfreeze systemapps or reinstall them and so on . If OTA fails after removing all changes you did (or you can remember) you should flash stock kitkat rom.
