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.

After downgrade to NCE 4.4.2, you have to OTA to NG3, OA1, and finally OC4 (5.0). You will lose root, and if you accept the 5.0 OTA you will not be able to root or downgrade anymore. Use this method to update to 5.0 and keep root,

Hey ho guys. I have a 5S with the Downgrade to NCE flash found on this board. I would like to have the latest Kitkat without updating to Lollipop and getting the locked bootloader. I just downgraded today to NCE and bravely did one OTA. It got me to NG3. Can I OTA again to get OA1 or will it jump me to OC4? Or should I use one of the methods here on the board to upgrade and totally avoid OTA? Thanks, later.

If you want root capabilities i wouldn't take any OTA. You'll still have to go back to NCE to root anyhow i believe. As far as the boot loader it is and always has been locked on the AT&T S5. The only method for root is towel root and I'm not sure if it'll work on NG3. If not you'll have to go down to NCE

Yeah, I should have preference that I am after root. But towelroot works on NG3, you can read about that here.

After I took the brave OTA I followed the threads instructions and it worked. There is a thread here that talks about root for OA1.
http://forum.xda-developers.com/att...to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120
It says just to take the OTA. I guess its still safe to take the OTA then after NG3? And I can't seem to find any rom on here thats stock OA1. Anyone know if I aren't seeing it? Thanks.

Most of the roms are based on nce or ng3. If you go to oa1 and flash a nce or ng3 rom your phone will be slow because of the different bootloader, and the camera is screwed up. I'd stay on ng3 and not worry about oa1. That's my opinion. I'm on 5.0 running the Twi5ted rom and having no problems with it. Most devs have moved to 5.0 lollipop and the 4.4.2 - 4.4.4 roms will be more and more abandond in my opinion.

Ah see I haven't tried any of the custom roms posted on here yet. But can I have NC3 as stock and on another ROM Slot (using Safestrap) have a Lollipop rom? Having one slot be 4.2.2 and the other be 5, basically. So the bootloader is different from NC3 to OA1, good to know. I'm glad I stopped at NC3 then. Thanks for your help.

I'm not sure on the different slots and bootloader mainly because when i used different slots the battery drain was unbearable. I don't know if they every fixed the battery drain issue when using different slots. It was bad enough that i just stuck to the stock slot and flashed only in that slot.
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...
Hey guys. I've been out of the loop. Is it safe to flash the DOK2 baseband/bootloader? Or should i just stay on COG2? Does it still have problems with root? You cant downgrade to 5.0.1 or 4.4.4 after flashing right ?

If you wish to stay on 5.0.1 or 4.4.4, then its not safe. Correct, you cannot downgrade. I tried going back to Darthstalker (5.0.1) and it bootlooped after going to DOK2 baseband/bootloader. I heard there is a way to downgrade the bootloader, but its not a very straight forward way
Plus, to add to that, there isn't a regular root method i do not believe. It's Systemless Root with means you don't have full root capabilities
Just upgrade baseband only like i did. Its fine then.
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.
