to create custom ROMs or modified bootloaders for devices with this specific "k80" board ID. Where to Find It preloader-k80hd-bsp-fwv-512m
Developers building custom ROMs for older MTK devices use this BSP to ensure the kernel communicates correctly with the display and memory. How to Use the Preloader File
Many white-label tablets (brands like Onda, Chuwi, Teclast, or Allwinner-based clones using MTK chips) rely on such preloaders. If the device shows no signs of life but connects/disconnects from USB every 3 seconds, the preloader is corrupt. You would use this file with in "Download Only" mode, ensuring the "PRELOADER" checkbox is ticked. : The primary image loaded by the device’s
: Indicates the RAM mapping profile. This file is hardcoded to initialize exactly 512 Megabytes (MB) of low-power volatile storage (LPDDR2/LPDDR3). Flashing this onto a 1GB version of the same motherboard will result in a hard brick. The Role of a Preloader in MediaTek Architectures
If you’re targeting an FWV display with exactly 512MB RAM and the reference K80HD panel, this preloader is a time-saver. For other configurations, expect to modify the source. Where to Find It Developers building custom ROMs
When the phone is connected to a PC for firmware flashing (unbricking), the preloader enters a special mode. The boot channel is usually set to MSDC_0 (Memory Stick Device Controller 0), which is the internal eMMC storage channel. The block size for data transfer is set to 0x20000 (131,072 bytes), which is standard for MediaTek boot roms.
