As i visited a friend's place he told me that his redmi phone was not powering ON and when he tries to switch it ON or connect the charger only the notification light starts breathing( blinking dim to bright) so i tried to solve the problem by disassembling the phone using a army knife as i was not having any tools with me, the steps i tried were successful and solved his problem.

Take care and do the repair on your own risk.

Thank you for watching. Have a GOODTIME.
