Amazon logo bootloop. (Possibly because of corrupt recovery?)

I’ve had this tablet for about 4 years now. I bricked it about 3 years ago but I don’t remember what bricked it. I tried to fix it several times but I never had success. I don’t have a lot of experience with android devices (I’m an Apple guy). My guess is that I was installing a custom recovery but it was for the wrong model. When I tried to boot it up for the first time in about a year there was nothing on the display. I reconnected the display cable and it showed the battery charging symbol when I plugged it in. Then it started to bootloop on the silver amazon logo (not the fire logo) as I remembered. It refuses to enter recovery which leads me to believe that I’m correct about the recovery being corrupt. As far as I know there is no other way to connect it to a computer. Apple devices have DFU mode which can always be entered even if there is no NAND flash chip at all. Is there any DFU equivalent for this device so I can try to flash the stock recovery? Its not a big deal, I bought this tablet for $50 4 years ago and its only worth about $25 now. It just annoys me that it’s been bricked for 3 years. Thanks!
