how could i connect my smart controller via pc even it keep restarting and it doesn't connect to my pc.

Is the USB Cable attached when restarting. Your USB cable may be suspect. Try a different cable.

Hi Panha Rith, thank you for your response. I feel sorry to know that still your smart controller is keeps on restarting. Would you be able to try a different USB cable if you have an extra, also try to let it connected to the PC until it detects by the PC even if it continuously restarting. If the issue persist, please send an email to our Support team to further assist you.
