R6220 Router might be bricked. Need help

I was doing a firmware update when my power trip. When i try to connect to the gateway ip to do the firmware update, it doesn't load and there is no internet connectivity. The router 1 and 2 is blinking continuously. I think my router has bricked. Appreciate help as im not sure what to do. I tried to use the tft2.exe but it wouldnt work and im not sure what steps have i done wrongly. Im not really good with router so might have a bit of difficulty understanding you guys explanation. Thank you for being patient with me in advance. Bless all!
