In this Tutorial i will tell you how to fix the following issues in CoolUI 8 and CoolUI 8 based RoMs:
*No Charging shown even when put to Charge.
*Power Button doesn’t work while phone is put to charge
*Volume Button doesn’t work.

Well , this happens as your phone is rooted partially which causes MTK logger to mess up the system

Don’t worry we can fix it. [TESTED IN NOTE 3 & NOTE 3 LITE BOTH]

1st Step:
[You need to be rooted – obviously ]
Open SuperSU
-Go to settings of SuperSU
-Scroll down and select “Full Unroot”
-Click on Continue

– Now it will ask “Attempt to restore stock boot image……..” Click on “NO” 

NOW YOUR DEVICE WILL GET UNROOTED AND IT WILL REBOOT.

2nd STEP:
When the phone reboots click , open directly TWRP and flash this :

Root and Factory Text Remover by Uday
( not required but follow this to ensure success  )

Now REBOOT TO SYSTEM.

Put the phone charging and check the power and volume buttons , it should be fixed by now

Now , Reboot back to TWRP and flash SuperSU.zip to root the device
Done , now you won’t face this issue next time – and if you do do this again
