Netgear R7000P Bricked

Hello,

I have a Netgear Nighthawk R7000P which I accidentally Bricked when I unplugged it while it was on. It is now in a boot loop, and TFTP doesn't work. Serial flashing used to show the boot sequence, but after coming back to it, nothing shows on PuTTY.

How would I go about fixing this?

BTW, this is the TTL adapter I used:

Any help would be much appreciated.

My major issue is that board

My major issue is that board_id shows incorrectly with U12H270T00_NETGEAR due to me flashing tomato with the wrong firmware (R7000 not R7000P). This resulted in bricked R7000P. I was hoping that nmrpflash would correctly set the board_id to show U12H270T20_NETGEAR and unbrick my router.

History context:
Netgear R7000P firmware -> WWDRT R7000P firmware -> Tomato R7000 (bricked system, tried to use other R7000P images but serial console to router showed that router rejected different firmware because the board_id now shows R7000 U12H270T00_NETGEAR, "nvram set board_id=U12H270T20_NETGEAR" did not persist across reboots) -> nmrpflash with "factory-to-dd-wrt.chk" (successfully did set to R7000P U12H270T20_NETGEAR and flashed to WWDRT R7000P firmware)
