No.   There is no hardware reset to disable bad firmware. 

However, if you can still ping the router, there is some hope of making your router work again.

If you can ping your router, use the tftp.exe program to download the latest firmware into your router.

The tftp.exe program is the same as the "Setup Wizard" for the BEFSR41 v 4.1 , and it can be found at this URL:

http://www.linksysbycisco.com/US/en/support/BEFSR41/download

The instructions for using the tftp.exe file are located about 2/3 of the way down the page at this URL:

Well there is no Hardware reset for these Router. If you have uploaded the Incorrect firmware on your Router or the Firmware is not uploaded on your Router Properly, the only way to recover the firmware on your Router back to the Default Linksys Firmware.

Follow these setps : 

Click Here Download the TFTP Utility to upgrade the firmware on your Router.

Download the latest firmware of your Router from the Linksys Website.... And save the firmware file on your Desktop.

• hold down the reset button for about 30 seconds, then unplug the device, while you are still holding down the reset button.
• leave unplugged for about 5 seconds, while you are still holding down the reset button.
• plug the unit back in, while you are still holding down the reset button.
• after about 5 seconds, let go off the reset button.
• go to the webpage of the router.
• you should see the special mode.

 If you are able to see the Speical Mode on your Router, then under the Administration tab click on Firmware Upgrade and select the Firmware file and click on Upgrade... 

Once the firmware is upgraded successfully then Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Your router is probably still covered under warranty.

Phone Linksys support.  If they cannot get your router working again, ask for an RMA number.  If you get an RMA number, you can return your router for a free replacement.
