Samsung Note 4 (N910F) DRK Problem - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello guys, I have a Samsung Note 4 N910F which a friend gave to me as a gift. He has been using it though.Did an upgrade to Android 6.0.1 and just before it booted, got an error that" DRK missing,Please install DRK first" then another one like "Please Flash ENG then install DRK". The phone boots ok but is a bit sluggish when typing or scrolling.The fingerprint scanner has also failed and gives an error when i try to set up. Please help solve this problem coz i really wanna use this device :crying:

How can I downgrade from Nougat to Lollipop 5.1 ?

Hello
I tried to downgrade my 7.0 A510F but Odin failed and Download Mode gave an error saying "sw. rev. check. fail. device 4 binary 2". I think it's because of old bootloader and I kinda guessed it will happen.
So is there a way to downgrade to Lollipop ?
Up

I try to do the same with my galaxy A7 but i cant find any aption cause I read that the problem is the bootloader seems like its a new version that its not compatible with older versions and something about knox that really i cant understant i hope you can fix your problem and share here

Can't install latest stock Rom from sam-mobile.

Guys I want to install a fresh stock Rom on my galaxy s7 Edge g935-fd because my front camera is giving an error saying camera failed...so I hope maybe it fixes it... but when I flash there is an error and following is written in download mode of mobile.. "cant install,device 4 ,binary 3". I know it's due to security reason that we cannot downgrade the bootloader but it's the latest Rom available on sam mobile. Any help will be greatly appreciated.

I had the same issue just wait till the latest rom gets uploaded and you'll be fine flashing it
these S7s are not EZ to mess with. I have a stock one I want to install TWRP on but might not after reading all these problems.
Would be cool if a Dev here would do a guide on the exynos with oreo 8.0.0
I would TOTALLY donate!
