Q: the wireless module doesn’t seem to work at all. I have tried many firmwares and it will not recognize. do you know of a specific fw that will fix this? or is this a bad board/module?

How to reflash BPI-R4.

Note: You can only burn NAND via SD card. If you need burn emmc, you need to boot via NAND.

mount /dev/sda1 /mnt/sda1 ;
echo 0 > /sys/block/mmcblk0boot0/force_ro ;
dd if=/your path/8G/bl2_emmc-r4-8g.img of=/dev/mmcblk0boot0 ;
dd if=/your path/mtk-bpi-r4-8g-MP4_1-EMMC-20250318.img of=/dev/mmcblk0 ;
mmc bootpart enable 1 1 /dev/mmcblk0 ;

For example, My firmware is stored on a USB drive, and the mount directory for the USB drive is usually /mnt/sda1. Since I have distinguished between 4G and 8G firmware, the final form is

mount /dev/sda1 /mnt/sda1 ;
echo 0 > /sys/block/mmcblk0boot0/force_ro ;
dd if=/mnt/sda1/8G/bl2_emmc-r4-8g.img of=/dev/mmcblk0boot0 ;
dd if=/mnt/sda1/8G/mtk-bpi-r4-8g-MP4_1-EMMC-20250318.img of=/dev/mmcblk0 ;
mmc bootpart enable 1 1 /dev/mmcblk0 ;

mount /dev/sda1 /mnt/sda1 ;
echo 0 > /sys/block/mmcblk0boot0/force_ro ;
dd if=/mnt/sda1/4G/bl2_emmc-r4.img of=/dev/mmcblk0boot0 ;
dd if=/mnt/sda1/4G/mtk-bpi-r4-MP4_1-EMMC-20241216.img  of=/dev/mmcblk0 ;
