Flash instructions:
1. On OEM firmware, login to the device (typically at http://192.168.1.1) and click 'CA'
in the bottom right corner -> Connectivity -> Manual Upgrade. Alternatively, browse to
http://<router IP>/fwupdate.html.
Upgrade firmware using openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.bin image.
Optionally install on second partition, after first boot check actual partition:
fw_printenv -n boot_part
and install firmware on second partition using command in case of 2:
mtd -r -e kernel -n write openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.bin kernel
and in case of 1:
mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.bin alt_kernel
2. Installation using serial connection from OEM firmware (default login: root, password: admin):
fw_printenv -n boot_part
In case of 2:
flash_erase /dev/mtd19 0 0
nandwrite -p /dev/mtd19 openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.bin
or in case of 1:
flash_erase /dev/mtd21 0 0
nandwrite -p /dev/mtd21 openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.bin
After first boot install firmware on second partition:
mtd -r -e kernel -n write openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.bin kernel
or:
mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq50xx-linksys_mx6200-squashfs-factory.bin alt_kernel
3. Back to the OEM firmware.
Download firmware from OEM website:
MX6200: https://support.linksys.com/kb/article/408-en/
From serial or SSH:
fw_printenv boot_part
in case of 1:
mtd -r -e alt_kernel -n write FW_MX6200_1.0.11.216041_prod.signed.img alt_kernel
else in case of 2:
mtd -r -e kernel -n write FW_MX6200_1.0.11.216041_prod.signed.img kernel
