Bricked MR3020 (e) failed to erase block

Hi,

I just bricked my mr3020 after I tried to restore to the original firmware and got this "(e) failed to erase block". It's kind of a hard bricked and all the led lights except the power button are blinking with 2 seconds interval. I was unable to enter the failsafe mode like I did before when I first bricked it. Is there still a way to repair this or do I just need to buy a new one?

Thank you very much :)
