Hi Asad890
do you want to delete all the messages from phone or only selected
if you want to delete everything then, you can try this
>settings -> apps -> messages -> clear data
>if you want to delete selected one then , settings -> apps -> messages -> clear cache, later try to delete those messages
let us know

NOTE:
Rate me If you are happy with my Resolution, Thanks 
the only way i can offer is delete one by one!clear data will delete ALL of yor txts
try to lower the number of txts from 25000
It will take some time,even if you delete a whole conversation.You can also use myphone explorer.
yes it will say it take time and deleting wiil apear but if you let it to be for hours at final not even a txt will be deleted
i face this problem on my ol' optimos one with 6000 txt...delet one by one..at the end getting tired and reset it to factory! 😐
