Downgrade from 5.0 stock to 4.4.4 kitkat - AT&T Samsung Galaxy S 5

Hi All,
I had S5 on 4.4.2 . Upgraded to 5.0 in following manner using OTA packages - using stock recovery
4.4.2 -> 4.4.4 -> 5.0
I would like to downgrade back to 4.4..4
Which method can I follow?
Want to downgrade because QXDM mode is not working in 5.0
Thanks

Not possible yet , I can't find a 4.4.4 firmware or tar file to try either . I Ave tried everything else I could find

The bootloader on 5.0 makes it impossible to downgrade. There are multiple threads about it.
No solution as of yet, and possibly never will be. They locked the piss out it.

[Q] Safe to root 4.4.4 after starting 5.0 update process?

Well, I checked to see if at&t had 5.0 available before noticing that 4.4.4 has a confirmed process for rooting now. It sounds like it's possible to keep root while updating from 4.4.4 to 5.0. So, I'd like to do the 4.4.4 root process before updating. The only issue is at&t doesn't seem to allow you to cancel the update process once started. What are my options for canceling the update / rooting 4.4.4, and updating the OS through other means?

It sounds to me that all u did was download the update, because when it installs the phone will shutoff. So just downloading it technically has no effect on your phone. So if ur check onn att galaxy s5 xda u should be able to find what zips u need and how the process works. Muniz ri is the op of the post to root on 4.4.4. god luck

Razr i - KitKat Downgrade ?

Hi guys,
as I am facing severe bluetooth connectivity problems since updating my Razr i to Stock 4.4.2, I am now trying to downgrade the Phone back to Jelly bean. The Bootloader is unlocked - is there any way to downgrade from KitKat without bricking the device?
I could also imagine trying one of the KitKat custom ROMs out here - but since the update I am unable to boot my phone into recovery (tried lebobo recovery flasher with latest version of TWRP, installation looks fine but launching recovery doesnt work :-/)
Any help on solving my problems is appreciated !
The best way is yo downgrade manually then.
See here http://forum.xda-developers.com/razr-i/general/index-razr-t2832722
And go to section "J". Than manually downgrade the version.

Downgrade to NCE

I have a Galaxy S5 (G900A), rooted on Lollipop 5.0 (0F3) using prerooted firmwares to upgrade from rooted kitkat. My bootloader version is still OA1. I want to downgrade now to kitkat so i can use safestrap. I was wondering if i could downgrade using the G900A_Downgrade_to_NCE.tar mentioned here and here, since i still have to OA1 bootloader, to downgrade without bricking my phone.

Yes you can use that downgrade file. I have used it many times. Your phone might run real laggy though after you downgrade. There is a thread somewhere that shows how to fix that issue. I'll see if i can find it for you.

Root for 5.0 lolipop without having to downgrade

I wanted to ask if there is a root for 5.0 yet without having to downgrade or using Safestrap ( I had no luck with safestrap nor with the downgrade). I was either hoping for something like towelroot for 5.0. Or even a custom rom with odin install.
