Is it safe to downgrade after 6.0.1 update - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Hi
Like so many other users have been reporting, I am having terrible battery performance after MM update. With the bootloader locked now after MM update, Is it safe to downgrdade to LP. I have been searching but i haven't found a clear answer yet.
My Model is SM-N910T 6.0.1, Baseband N910TUVS2EPG2 and Build No. MMB29M.N910TUVS2EPG2 .
Can someone point me in the right direction, method, guide so I can downgrade, Root and may be install a Custom ROM
Thanks

I have the N910T and I can downgrade to DOK2 without problems. I heard people with N910T3 may have problems.

If you already rooted your device and want to stay rooted and upgrade to lollipop, follow the directions in this post:

If you are not rooted (stock) and want to stay stock but upgrade to lollipop, follow the directions in this post:

Thanks for reply
But I didnot find lollypop 5.0 update for this specific Base Band Version :N900AUCUCNC2
My device is not rooted I just want to install original at & t lollupop update..
Thanks
You don't need to find the nc2 baseband... you said you are already on NC2. NC2 is kitkat.
If you want to install stock lollipop 5.0 on the att note 3 n900a phone... then you need to install the lollipop rom that ends in OC1.
You cannot stay on NC2 and have lollipop, because the current stock lollipop is OC1.
You don't need to be rooted to install it. You need to use ODIN to install it and you will still be stock and not rooted.

Help, G870A-0F3, Downgrade.

I am wondering if I can downgrade my Samsung galaxy s5 active to "NE4" (The stock firmware which i can use towel root) from "0F3" (The newest firmware) does anyone know a guide or is it just not possible to downgrade/root once its at 0F3
I heard that the G900's cannot but the G870's can.
If the bootloader was updated to OF3, downgrading is almost certainly not possible. See http://forum.xda-developers.com/att-galaxy-s5/help/question-regarding-root-s5-active-t3185231 and http://androiding.how/how-to-keep-root-and-update-att-s5-active-to-of2-build/
The first link has instructions for finding out which firmware's bootloader is installed. The second link contains reports from people who attempted to downgrade from OF2 and OF3 bootloaders.
I suggest killing future OTA updates, in case a root exploit is found for your current firmware that doesn't exist in a future update.

need little information...

i am using android version 5.0 with baseband version G900A AUCU4BOF2.....

Downgrade question

Simple question guys can i downgrade my G920A 6.0.1 to 5.1.1 or 5.0.2 , with odin or anything. i accept the risk

Downgrade Options? SM-T710 Nougat

I have a tab s2 sm-t710 on nougat T710XXU2DQCL that was installed OTA and would like to know if i am able to downgrade to 6.0.1. The device is 100% stock and was wondering if ODIN would give me any grief about downgrading. The PDA number of the 6.0.1 file is T710XXU2CPK1 (Cellular South).
Thanks
On paper, I think you should be fine. :angel:
I'd also like to know this as battery life seemed much better on 6.0.1 for me.
i did downgrade my T 815 from 7.0m to 6.01 using odin. didnt face any difficulties. i did a complete wipe/format after i downgraded .
Can you not downgrade with TWRP as well?

I used Odin and firmware downloaded from sammobile and it worked flawlessly. I've performed downgrades on over 100 tablets so far and they have all worked good.
Downgrded my t713 long time ago and didn't have a single problem, you just need to download a compaitable firmware from sammobile!

You're safe to downgrade as long as it's allowed. Older builds will fail immediately so there is no harm to downgrade.
I've seen a few people asking about downgrading. Whats the reason behind this? Is N glitchy?

N does not work at all well with DJI drone remote controllers. I foolishly updated my brand new SM-T719Y 8" and Now I cannot connect to my drone at all. I have an pre 2016 Tab S2 on Android 6.01 and bingo works.
This size pad is the preferred size for drones and has enough grunt to provide stutter free vision. Cannot comment on anything else about N as this pad will only be used for my drone...

Hi Beut,
I have been trying yo downgrade my Tab S2 SM-T719Y LTE from Nougat to 6.01 and have correct downgrade and Odin. Every time I try to downgrade it fails straight away, so I was wondering what you ment by "as long as it is allowed" & "older builds" will fail immediately.
I need to get this happening as I cant fly my drone.
Cheers Yts...
I don't have your model so it cannot verify. However, other models I can downgrade to older builds close to the Nougat.
Like SM-T580 or SM-P580, both are Android 7, QF1 and QE4 respectively. I can downgrade them to PL4 or PL2, Android 6 but not the PG1.
Q: 17 or 2017
P: 16 or 2016.
The second letter is the month it's released.
You also need the right bootloader, different OS has different bootloader. Many just flash the AP file only without bootloader, it'll failed when downgrade.
Is it possible that you cannot downgrade Nougat to 6.01 as every time I try on my SM-T719Y Tab S2 LTE, it fails straight away. I have tried 3 different downloads and all failed, but Odin will let me overwrite my Nougat with a downloaded version of Nougat from the same web location as I got one of the 6.01 firmwares from.
Here are my fail messages.

Is it me or is it this model of the Tab S2 SM-T719Y????
When downgrade to MM you need the BL ( Bootloader ) goes with the AP . Boot loader of Nougat is not the same as MM , however bootloader of LTE version is locked
Sammy doesn't want you to downgrade.. nougat is planned obsolescence, I'd say.

Hey I've been trying to downgrade my T719Y for days now. Constantly failing and googling everything I can to find where I'm going wrong.
How would I know if I have the LTE version? And if I do and the bootloader is locked, does that mean I can't downgrade?
If I don't have the LTE version, you're saying I need the bootloader and AP to downgrade? Where can I find the bootloader?
I'll keep searching and trying but this is wearing me down. Any assistance would be greatly appreciated. My surveyors can't do a damn thing with our giant UAV until I fix this
LTE version is the one that has SIM, usually it's next to SD slot. Most LTE versions have locked bootloader, that's why you cannot downgrade firmware.
I just kept an older phone for apps available only for 6.0. Like scr recorder. Otherwise there are no reasons to downgrade
