Raspberry 4 Long 5 Short flashes

My raspberry pi 5 8gb wont boot up, it just constantly flashes 4 long 5 shorts even with just only power attached. Im using the official power supply. help

Try to reflash the bootloader.

Hey @Arif282635, welcome to the forums!

As seen in the Raspberry Pi 5 documentation (pictured below), this error code simply refers to “fatal firmware error”.

This is typically either a bootloader error, or a hardware fault. As @lia262073 advised, try reflashing the bootloader.

I’m assuming you purchased this product from us, if this is the case and reflashing the bootloader does not work, contact us at support@coreelectronics.com.au with your order number and a link to this forum post so we can assist further.
