Thanks Team M.A.D, time and again you have proved that your ROMs are the best for Coolpad devices. I'm stoned to see how you release ROMs without major bugs. Hats off!! A big fan of yours. Didn't even flash a single custom ROM ever since you released Mad os Nougat back in August.

Thank you so much M.A.D. Team for all your efforts.
Happy New Year guys.
I have a made a quick video on How to install this ROM.

Bugs and it's probable solutions

I am going to compile all the bugs I will encounter.
Try these on your own. These worked for me it may or may not work for you.
1. Screen Recorder is not able to save the video. (DU is saving but most of the time black and white and some yellowish lines) AZ and ScreenCam are not even saving anything.
probable solution: NONE

2. Performance lag is there. probable solution: flash magisk 15.2 and then after rebooting install latest magisk manager.
e.g. Typed whole word then it shows up suddenly.
When on call it takes time to reach Home after clicking Home button

3. Network drops when GPS is on (Airtel 4G SIM).
probable solution: delete system/vendor/bin/mtk_agpsd

I will add others when encounter.

I believe that network drop is due to low LTE signals of Jio and in mados we have fatser network switching when the signals are below specified limits. As Jio doesn't have any fallback networks(3g or 2g) it causes the network to entirely drop and it comes back when signals are good enough @DerTeufel1980
