kindle is bricked, pc shows tate, but cant get adb to work!

hello

i have a kindle that needs a new firmware, along the path of fixing i made a fastboot cable, pc wasn’t able to detect the device at first however, if i push the plug into the kindle, it gets recognized as tate pvt 8, which is good but when i use the adb drivers for it, i get “this device cannot start error 10”, im going to try on a fresh install of windows then linux, if the problem persists i may change the usb port

whats ur input, will this be useful and not a waste of time ??
