Welcome to the forums @williamooi.
Verify that you have downloaded the correct firmware for your model. Be sure you unzip it and compare the hashes to ensure the download wasn't corrupted.
Restart the computer you're using to perform the update with. Note that 'Restart' is not the same thing as 'Shutdown'.
Do you have any USB devices connected to the router? Safely remove them via the GUI, physically remove them from the router, then reboot the router via the GUI. You should now be able to flash the firmware you want.
With no USB devices, reboot the router via the GUI, and then flash the firmware you want.
If the above doesn't work, try an electrical reset. Leave the power button 'on', on the router. Unplug the power cord from the router and the AC wall outlet. Wait a few minutes and plug them in again. See if flashing the firmware you want works now.
Finally, if none of the above works, you may need to do a full reset to factory defaults. Use the appropriate method for your router from the link below.
Hope this helps.
