Can't seem to figure out the way to enter the cable shifter which broke while riding!!!
Can't also find a manual or video out there helping me to replace it.

For the RD, shift to the smallest sprocket i.e. activate the inner lever for as long as it clicks. Pull the brake lever, hint: open the caliper in the way you would to remove the wheel. That way you can push the gear cable out of the brifter.
