Can't connect after changing MySQL root password in WAMP

P.S----I HAVE NO ACCESS TO PHPMYADMIN

Answer 1

go to your wamp installation drive, and then go to wamp folder traverse it if the drive is C: and installation folder is WAMP C:\wamp\mysql\data\ you will see the folder as the name of your database here copy it to other place and paste it after reinstall phpmyadmin in the same position

Answer 2

Okay, assuming that you know the new/old/current root passwords run the following

mysqldump -u root --all-databases -p

This should ask you the password and dump sql onto the stdout.

To save it to backup.sql,

 mysqldump -u root --all-databases -p > backup.sql
