[install TWRP]How to unlock bootloader on Samsung Galaxy Note 4 / N910F / Marshmallow

Hello,
I'm trying to install TWRP recovery mode on my Samsung Galaxy note 4 ( version N910FFXXU1DPE3) running under android 6.0.1 Marshmallow
I have rooted my phone (installed the CF_Autoroot stuff with Odin) , but it doesn't seem to be enough, because when i install TWRP and try to boot in recovery mode, my phone show a message "unable to do normal boot" and switch in "download mode" and get stuck in it.
I Fixed it to work normal again, and try to find what i did wrong :
And It seems I missed to "unlock" my "bootloader".
I try to find on internet how to do it, but i can't find anything
Either the file links are missing,
Either it's only for Android 5
Either its for another version of Galaxy note, and not for mine : N910F
I can't find any good tutorial to do it, can you help me with this ?
Thank you !
I have the exact same problem, I know this thread is really old.
But I can't find anything about unlocking the bootloader for n910F, and as above - it's definately locked because I can't change the recovery,.

TWRP help

I updated to android 10 and tried following the tutorial to get TWRP on it, but everytime I try to launch TWRP it hangs on the logo.
Is it that TWRP has to be updated for a70 android 10? or am i doing something wrong?
TWRP does not work with Android 10 at the moment for the A70. I do not know about other phones. Android 10 changed the way they use recovery so it will take a while. https://twrp.me/site/update/2019/10/23/twrp-and-android-10.html
Hi, I also had the same problem, the logo screen remains fixed once I enter Recovery! We have to wait for the developers to find a solution in this regard. Regards! ??
Revert back to android 9 as android 10 is unstable for A70.
But if its working fine for you then wait for twrp to get updated

Can i install LineageOS 18 (Android 11) on my S20+ that has been upgraded to official OneUI 4 (Android 12)

Hi,
as the title states, I am looking at installing LOS 18 on my S20+ (I know LOS 19 is out, but i need the older version).
My phone currently is fully stock (boot loader locked) and on OneUI 4 (Android 12).
A quick search on the forums seems to indicate it's not possible to downgrade to an official Android 11 ROM on the phone even using ODIN.
the device as an exynos device.
i managed to get it to work by installing the Android 11 stock rom using odin.
the first attempt it got stuck on boot loop, then I attempted using the HOME_CSC file, it got stuck at prism.img
on restarting it gave an error on failed update.
even then plugging in the USB, OdIN was able to detect it and trying installing it again worked.+
