I've installed the New Mini 2 Firmware 01.07.0200 Release thenmy RC is not turning on or even charging. Have anybody facing with similar problem? Please help me to fix it.  

Hi, gnanatheepan. Thanks for reaching out, and apologies for the inconvenience. Please refer to the following troubleshooting steps to help resolve your concern:
1. Ensure that the remote controller is powered on correctly.
Power-on method: Press the Power Button for one second, then again, hold it to power the remote controller on.
2. Please press the power button once to check if the battery level LEDs are light on. If not, please charge the remote controller, then try it again. If the remote controller cannot be charged, please replace the charger if possible.
