Nice.

I found this for the future. Since you had stock recovery.

DO NOT follow everything here. It's for reference only.

https://blog.zauberstuhl.de/flash-your-recovery-image-via-adb-shell-on-android/

Commands are:

adb shell

su (NEED TO BE ROOTED to access partitions)

dd of=/dev/block/mmcblk0p10 if=/external_sd/recovery.img

You are essentially manually flashing TWRP recovery.img via a command line directly to the partition.

So from here https://dl.twrp.me/treltexx/

You would download twrp-3.1.1-0-treltexx.img and rename it to recovery.img and copy it to your external sdcard or sdcard.

If using SDCARD you would obviously need to change the command line to dd of=/dev/block/mmcblk0p10 if=/sdcard/twrp-3.1.1-0-treltexx.img

Flashing it Old School. :cool:

If you don't have adb loaded

This requires a Windows PC though.

For future reference below is a list of partitions of the SM-N910C.

So can you flash a modem this way..... Yes !

dd of=/dev/block/mmcblk0p13 if=/external_sd/modem.img

Proof it works.....

Notice I did not change the TWRP filename to recovery.img. Helpful if you want to track what version of TWRP.

Didn't have time to take of a pic of reboot into TWRP to show I'm on version 3.1.1-0. But I am....

As [MENTION=8233634]Voytec83[/MENTION] stated, it is not an issue. IF you have flashed the correct recovery and kernel for your phone.

It is a message warning not a problem. It is simply saying the kernel and recovery are not stock. That's it.

If you flash back to stock recovery and stock kernel, you will not see this message.

Security enhanced (SE) Android is based on SELinux, a set of kernel add-ons and access control tools that let apps and other software run with only the minimum privileges they need to work correctly.

Since TWRP is a modded recovery and the kernel is modded, to allow us to do what SEAndroid was made to prevent, it's simply telling/warning you of this fact.
