Downgrade to kitkat with TWRP from Marshmallow - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Hi,
I have Note 4 N-910T with Kitkat baseband version N910TUVU1ANK4 and the phone is fully unlocked i.e. I am using it outside USA and on other network sim not T-Mobile
I want to update it to
EPJ2 6.0.1 Marshmallow BL and Modem (as of October 2016, Latest)
https://drive.google.com/open?id=0B6...WRvVmJWTzItS0E
My question is
1. Should I first flash TWRP on phone and take back up and then flash the Marshmallow firmware ?
2. Will my phone lock to T-mobile network after update ? What If I flash some custom Marshmallow ROM, will it still lock ?
3. If it is locked or something bad happens, can I safely restore the TWRP back up I created ?
Please help me
Thanks
Aiden

You cant flash via twrp
First you have to flash 6.0.1 full stock firmware via odin to get marshmallow bootloader/baseband.
And dont worry it will not sim lock the device
After that you can flash twrp and flash any 6.0.1 custom rom
Keep in mind once you flash lollipop or marshmallow you cannot go back to kitkat. Your bootloader will be locked and impossible to run kitkat again.
And also your twrp backup of kitkat will no longer work.
I suggest you stick with kitkat cuz it's best for note 4 till date.many users are pulling their hair to go back but they can't. Marshmallow is good in performance but kitkat is best in battery life and speed.

But I was able to downgrade my W8 N4 from MM 6.0.1 to stock Kitkat 4.4.4 by Odin 3.09 without any problems, It doesn't lock the BL, I am not sure for other models but at-least mine BL was not locked.

i have gone up , down and sideways betweeen 4.4.4 and 5.0.2, with these, 1 thing to note updates may be done with locked bootloader, BUT downgrades require unlocked bootloader.

[Q] Anyone downgraded from 5.0.2. to 4.4.4

Hello, I have upgraded to 5.0.2. via OTA a few days ago. My phone was RetEU .23, and the update notification that 5.0.2. became so annoying, so I decided to give it a shot. Lollipop is a disappointment for me, battery drain issues, lagging all over the menus, slow dialer, the phone was running better with KK installed, so I want to return back to 4.4.4.
Unfortunately there is no clear opinion whether this could be done, some say that when you have 5.0.2. bootloader installed with the OTA, you cannot go back, others say that it is no problem to do so. Really confusing.
Anyone tried to go back to 4.4.4. after getting the OTA? Could you please share how did you do so? Unlocking the bootloader and flashing one of the 4.4.4 stock ROMs from the General Section?

Hello,
i actually switched from 5.0.2 back to KK 4.4.4 from Pizza_dox
when your bootloader is unlocked and you have TWRP installed
follow these instructions
1, go do a factory reset
2, go to advanced wipe and select :dalvik cache/system/data/internal storage/cache
when you did that there is no system on your phone so when you restart you will be going into an endless bootloop.
3, go press install and select the Microkat.zip file from Pizza_Dox
when that is done you have agian kitkat on your device
i think there some other methods but this is how i did it succesfully.
Also dont forget to make a backup because you will lose everything.

Thanks for your comment. I actually plan to go back to the stock 4.4.4. I have a basic idea of bootloader and things but not deep into this and have never done it before. From what I have read , I will have to:
1. First I need to unlock the bootloader, as per the instructions in the Moto website.
2. Then I will need to do a factory reset. (settings-secuirity-factory reset or some other way of doing this?)
3. Download 4.4.4 firmware + script.
4. Start up with Power+VolDown buttons and have bootloader menu on screen
5. Run the downloaded script from its .bat file.
6. Wait for some time for the flashing to end, then have stock 4.4.4
Please correct me if something is wrong or missed.

What i did...
Download the correct kk stock rom
Setup my drivers and mfastboot correctly (simple fast boot works too)
Unlocked bootloader. (Voids warranty coz gives bootloader status 3)
Reboot in bootloader now...
Flash all files of kitkat except gpt.bin and motoboot.bin (they never flash for me lol )
Flash all other files (i typed filenames manually)
Fastboot reboot
Ps - no matter what i do..i have not been able to lock my bootloader once i downgraded from 5.0.2 to 4.4.4
Locking bootloader works well on 5.0.2

well guess im gonna try - but no need to do, as makes no difference except to downgrading.... So best off unlocked
simply use the 4.4.4 link in my signature and pick firmware 2 or B called DSDSALL to go back to 4.4.4 .23 ret(xx)
So, it has been confirmed by several forums that when you have officially received the 5.0.2 OTA download update, you cannot go back to KK.
It has something to do with the new L bootloader. I guess that there is no way of doing this, up to now at least. Don't know if someone has tried and succeeded.
When you have flashed the 5.0.2. OTA however, you can have KK installed back, as most of the users on xda.

Help! How to downgrade from marshmallow ( nexus experience rom) to lollipop (stock ro

Can anyone pls tel how do i downgrade from marshmallow 6.0.1 to lollipop 5.0.2?
Currently my bootloader version is 48.83. I dnt remember what it was on lollipop. Pls help!
Just use your backup that you made prior to upgrading to Marshmallow. If you don't have the backup, just flash a different ROM. Plenty of guides on the site.

I have made the backup. But i have heard about many people hard bricking the phone when trying to downgrade and then again upgrading via ota. Thats why i askd.
If u are on custom rom other than motorola marshmallow soak test ota.. you will not get ur phone bricked when downgrading. Hard brick occurs if u downgrad from soak test ota to lollipop. In your case u just need to flash retaildsdsall firmware via fastboot mood. Search for tutorials for reverting to stoc 5.0.2.
Just DON'T CHANGE BOOTLOADER. You shouldn't be able to downgrade bootloaders but Motorola screwed that and with M bootloader you "can" downgrade, but bootloader downgrade results in BRICK. Just flash the rom you want, EXCEPT THE BOOTLOADER. For custom roms you shouldn't have problems.

I have made a nandroid backup. Currently m on nexus experience rom. One of my friend was in resurrection remix (marshmallow) he faced some bugs so he came back to lollipop. It worked fine for him. But when he tried to flash the soak test ota, he hard bricked his phone... Why did that happen??

All I can say is that I was on Nexus Experience 10.0.4 (Marshmallow) but could not get adopted storage to work so restored my previous AOSP lollipop ROM from TWRP backup and no issues. My Bootloader is 48.82. I have never used the soak test version or OTA version of marshmallow.
I have also in the past restored stock lollipop V5.0.2 from other lollipop versions with no issues.

My bootloader is 0×4887 I am running a stock mm and I wud like to downgrade to lollipop to use the stellar kernel way shud I do...???pls help
Just a noobie....
Sry if tat was bad English..!!
Just don't downgrade your Bootloader and you should be fine, if you're using an easyinstaller script to flash stock Lollipop make sure and remove the lines of code that flash motoboot.img & I'd also recommend removing the line that flashes gpt.bin to be safe.

Has anyone confirmed downgrade from MM?

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 ?

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

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....

Oh my bad, you're trying to downgrade. Downgrade not possible for t3. Flash stock 6.0.1, problem resolved.
I am happy with marshmallow but when i was running lollipop the ( unable to mount preload error was not there )
I did flash 3 times 6.0.1 firmware but the error still came up in red letters when i do wipe data factory reset.
Any solution to fix that ?
I'm trying to downgrade my n910t3 phone as OP too. Currently I'm on N910T3UVU3EPJ2, never rooted, never flashed with custom ROM, Knox counter 0x0. Is it true that It's not possible at all to downgrade it?
If so, is it mean that you can still flash the older 6.0.1 MM stock ROM or it is not possible as well?
