Has anyone confirmed downgrade from MM? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

As the thread states....has anyone tried to flash stock DOK2 firmware from the new MM update? I have searched and asked many questions but have not gotten a solid answer. And if no one knows or no one has tried yet, would someone who had already taken the update be willing to try flashing stock DOK2 firmware? For developmental purposes. Thanks in advance. ?

Anyone got root for Marshmallow?

Root works perfectly fine. Use SuperSu Systemless root. I believe the version number is 2.74-2. It's the latest beta if I'm not mistaken.
First use ODIN to get TWRP onto the device and then flash the supersu zip like usual.

I was thinking of just using flashfire to flash BL and modem only then install the rom..that way it doesnt overwrite recovery... bad idea ?

Yes, bad idea. No shortcuts on base updates.

I was able to downgrade to DOK2 but I only flashed the bootloader & modem file not the entire firmware

If you flashed BL then we are good. I wonder if the MM bootloader is like n910G.....they couldn't go from 5.1.1 to 4.4.4 but when they got 6.0.1 they were able to got back 2 steps to 4.4.4.like a magical BL unlock ha

What files did you use? I tried flashing the entire dok2 firmware through Odin and kept getting stuck in a bootloop. If I could just flash those 2 files that would be great.

I have downgraded from a full PE3 to OK2. Worked fine.

Awesome...that makes me feel safer...I might try to odin nk4 later just for ships and giggles haha

does anyone know if you can downgrade from MM PE3 to KK ANK4? I know that you can't go from DOK2 to ANK4. Love firekat too much

I had a T-mobile Note 4 (N910T) on 5.0.1 , downgraded to KitKat 4.4.4, when Lolipop 5.1.1 came out I upgraded. rooted, and then flashed custom rom Tekxodus .. phone used to restart randomly .. later discovered that once you upgrade OK2 you get locked and no longer can downgrade to KK.
later on, the phone started to give mmc error and then just died.
Lesson Learned, stay on 5.0.1 or downgrade to 4.4.4 and stay there.
I still wonder if Android 6.0.1 Locks down the downgrade process to 4.4.4. I doubt it will allow it.

Ok. You just downgrade, but I have a question.
After you flashed BL and CS, you still have to flash the firmware, right? So, I have to have the firmware OK2 too, right?

Yea if you want everything to be OK2 but its not necessary....if you are gonna use twrp, u dont need to odin recovery....and if you are gonna use a custom rom instead of stock then you dont need to odin system...so basically anyone with twrp and a custom OS is only using BL and Modem

But i always just flash it all just to be thorough....

Kitkat wifi issue

Haven't seen a thread for this, so here it goes. I followed one of the guides to get me to kk. I was having trouble doing ota so I flashed the 2400258.zip file, and rooted with tr. Not sure if the problem was there before root, but after every restart, I have to re enter wifi password. I have tried udroid, and firekat ,and still same issue. Any help is greatly appreciated, thank you. Would also like to add my wife is on 100% official kk, rooted with tr, and she has no issues.
You must be on nc2 rom with old bootloader.
i have the same wifi issue.
1. Flash the nc2 bootloader
or flash a older rom that is not nc2.

What thread is the bootloader, and if it's Odin, what option do I flash it? ap?
Everybody say do not flash new bootloader cus you can't downgrade back to jellybean. But why would you want to go back?
Check the general thread titled nc2 bootloader/download fix.
Thanks bud. I'll give it a go.

Reverting to G900AUCU1ANCE from G900AUCU2AND3 (AT&T)

Hi all,
My phone is using G900AUCU2AND3. It has been rooted and I also removed a lot of bloatware with Titanium Backup. Because of this, OTAs are failing.
I would like to flash the stock rom G900AUCU2AND3 again, so I can do that. However, I haven't been able to find it.
I only found G900AUCU1ANCE.
If I flash that ROM with ODIN, since that I'm downgrading, will I run into any issues?
Thanks a lot for your help.
the AND3 software is not out. if you have to fix a hard brick, bootloop or want a fresh start, you will need to downgrade to the ANCE firmware, flashing via odin.

This file, flashed via odin, will downgrade you to stock NCE ( minus the bootloader). Once on NCE you can take the ota update to the latest firmware, NG3:

The file from sammobile includes the NCE bootloader. Since you already updated the bootloader to ND3 you are unable to downgrade the BL back to NCE, hence my file minus the NCE BL.

The reason why i want the stock firmware is becuase i flashed a rom through SafeTrap and it has some features missing which i use.
I've pretty much googled all night however on sammobile i only get the NCE firmware and i believe i cant flash that through ODIN since my baseband is on NG3, Right?
You can flash nce even if u've gone to ng3. I thought same but works as long as u flash all 3 files and not BL (bootloader)

Thankyou so much for taking out time and helping me out. So what you're saying here is that after i download the NCE firmware i'll get 3 or more then 3 files, right?
If thats the case then it would be very easy for me to flash that through Odin.

Stock G900a downgrade from Marshmallow to Lollipop

Searching via cell isn't great for me at the moment. I've found a few threads with lollipop files to use in Odin. But I haven't read anything that says it's simple to flash them and downgrade properly from Marshmallow to Lollipop. Is there a tutorial/file thread already on here that I am missing via search? Is this something I can do without rooting?
Da hell is that chipmunk woman
Sammobile doesn't have the stock 5.1 firmware.. is that an omen against downgrading?
Most of the posts ive read are indicating Marshmallow is not able to be downgraded, bootloader locked.. looks like a dead end
It's a different boot loader, will not be able to downgrade. There is no root option at this time as well.

sorry, but i disagree. i just flashed from 6.0.1 to 5.1.1 using odin and firmware found here on XDA. I have no problems with phone so far.
At the time of my post months ago, this was not possible. It is very possible now, I have also done it.

This is for the AT&T model, I haven't been able to crack into mine. I have battery issues since marshmallow and want to go back to 5.1.1 as well... where did you get the files, and what process did you use?

following this guide for rolling back to LP, work for me downgrade from MM and getting root on LP.
Mine didn't... version DPH4, october 1, 2016 security patch, odin gave me an error something like level 4 > 3 and didn't start the reflash process. I was able to reflash the same 6.0.1 and its not the same as what was on there, so maybe the ota updates had a problem? I'm still locked out of downgrading.
Mine also from DPH4 oct 1, 2016. Having issue with lte, i cant receive call but i can make call. So im rollback to COI5 and follow the instruction from page 2. Get odin 3.11.1 to flash BL,AP,etc. Have you try with other usb cable?

i also have the at&t model, but used some info in this post: https://forum.xda-developers.com/att-galaxy-s5/general/guide-merry-christmas-heres-t3516196
i used odin to flash full OI5 firmware, minus the bootloader file. Only use the AP, CP, and CSC files. the bootloader is the same. and really, i had already flashed the PA2 build earlier that day i remember now. would probably do that first. flashing the PA2, i used all four files, BL, AP, CP, and CSC . they both flashed the first time, if they dont then try a different cable first. usually that is my issue.
so , i flashed from 6.0.1 down to 5.1.1 pa2, then down to oi5. still have no problems other than getting root..... im focusing on bootloader now, i have unlocked them on htc's before, but havent tried any other phone yet. the work continues tonight.

Bootloader/Modem?

Hi guys. It's been a while since I rooted this phone because my work wouldnt allow it. Anyway I finally got it rooted (v 6.0.1) and TWRP going. I was thiking about flashing the CMRemix rom and they mention "You MUST be on the Latest Bootloader and Modem for your Carrier - D0K2 for Tmo SM-N910T". Where do I even find out if im using that? My current baseband is N910TUVSEPG2 if that helps.

Choose BL tab in odin to flash bootloader
Choise CP tab in odin to flash modem
Must Flash both files otherwise simcard and wifi will not work in cm13.
On cm13 first boot if sim does not work just restart device and it will work fine
