Preloader-k80hd-bsp-fwv-512m | Updated

: Never flash a 1G (1 GB RAM) preloader variant over a 512m device layout. An improper RAM structure configuration will permanently disrupt the BROM protocol, creating a state that can only be fixed by physically opening the casing to short-circuit hardware test points.

Solid for legacy FWV display support – works as expected with 512MB RAM config

The naming convention of this file provides crucial data about the hardware it supports: preloader-k80hd-bsp-fwv-512m

Because it specifies "512M," this file is required when replacing an EMMC chip to ensure the controller recognizes the correct RAM size.

If this happens after flashing, you have likely flashed an incompatible preloader variant (e.g., a version meant for a 1GB RAM board instead of your 512M board).

: Once RAM is ready, the preloader loads the lk.bin file, which manages the boot animation and fastboot mode. [Powered Down Device] │ ▼ [Hold Physical Boot
