thank you mohamad, i did this step and password changed succesfully but when reboot and try to login with my new password it's not working

Could you please repeat the steps located in this KB : https://support.f5.com/csp/article/K35811337
maybe there are some missing points , as I followed it and tested it on my lab and it worked great. 

> also make sure with your bootlocation such as "HD1.1 or HD1.2 .... " to mount 

mount /dev/mapper/vg--db--sda-set.2._config /sysroot/config
mount /dev/mapper/vg--db--sda-set.2._var /sysroot/var

there are platforms uses vda instead of sda so you need to change it in each mount script. 

Try it and keep me updated
