Samsung Galaxy Note 5 Rooted Firmware lets you underclock overclock

A new ROM on xda developers has surfaced that lets you attain root by flashing a pre rooted firmware. It is based on official Samsung Galaxy Note 5 source N920CXXU1AOGE and is compiled with Google ARM Toolchain GCC 4.9. It roots the system automatically and installs busybox as well. Of course this voids the warranty as it bumps knox counter to ‘1’. It also lets you overclock underclock Galaxy Note 5 as it install a custom kernel that lets you do it. It works only on the SM-N920 variant of Galaxy Note 5.

Samsung Galaxy Note 5 Rooted Firmware

* SELinux PERMISSIVE  (for Titanium Backup and other apps to work correctly)
* adb insecure
* init.d script support (drop in script & set permissions to 755 or 777 and reboot)
* Possible Screen Mirroring / AllShare Cast fix
* Secure storage = false (should prevent WIFI settings & passwords wiping on flash)
* Synapse app support for many kernel configurations

Rooted firmware: Installation instructions

Uninstall any CPU control apps, tweaks and init.d scripts etc.
Recommend: Disable or remove KNOX (you can disable with Synapse once kernel is flashed)
Install Synapse app from Google Play.
Device Settings:
Enable Developer Options > OEM UNLOCK
If flashing from previous SkyHigh kernel > Device settings > Applications > Synapse > Force Stop > clear data
If not installed > Install SuperSU from Google Play: Boot into Download Mode & connect to PC and Flash SkyHigh kernel with Odin 3.10.6 in [AP].
After boot:
a) wait at least 120 secs to stabilize
b) Open Synapse
c) Tap "Understood"
d) Tap the "" to apply new defaults
IMPORTANT: Synapse > FS > [Wipe Cache & Dalvik-Cache Reboot] !! (maybe help with reboot issue during call)
