I am facing a critical problem with my Raspberry Pi 4 B(8GB) after using rpi-update (which installed a bugged kernel and kept on overloading the processor and the Green LED kept on lighting continuously until I shut it down...) I tried reinstalling many distributions such as Kali and Raspberry Pi OS for more than 4 times and it always fails to boot (kernel panic even if it is a fresh install without any changes) and the keyboard&mouse are not working and sometimes it can't transmit voltage to the mouse and keyboard and they aren't even lighting (those RGB LEDs)...

after a lot of attempts I found that Keyboard&Mouse seems like it doesn't transmit or receive any data except when the ACPI and CPU reach 40 Degrees Celsius I don't really know how but this is a big possibility

• please note that i tried reflashing the boot loader but that didn't work too...
