Since versions change, use this as a roadmap for your research:
Connect your ISP modem to one LAN port (configure as WAN via network -> interfaces) and your home switch to another LAN port.
Remove the rubber feet to find hidden screws. Open the casing to reveal the PCB.
Plug a USB hard drive into the USB 2.0 ports. huawei ec6108v9 openwrt
If the box boots, you will see OpenWrt's familiar ASCII art (in the serial console). It will have a default IP of 192.168.1.1.
Connect your PC to the LAN port. Run:
ssh root@192.168.1.1
(Password: usually blank or password/admin – check your build notes). Since versions change, use this as a roadmap
Once inside, expand the root filesystem to use the full eMMC:
fdisk /dev/mmcblk0
# Create new partitions
sysupgrade /tmp/openwrt-sysupgrade.bin
You cannot flash OpenWrt over the stock Huawei firmware directly. You must first flash a secure boot or unlocked bootloader.
Official OpenWrt does not natively support the EC6108V9. This is a "target of opportunity" for community developers. The most successful ports come from the OpenWrt on Set-Top Box community, primarily on Chinese forums like Right.com.cn and GitHub repositories (e.g., hdhomerun or darkflame builds).

These custom builds use the OpenWrt 21.02 or 22.03 codebase, backporting drivers for the Hi3798M SOC.
Critical note: The EC6108V9 has multiple hardware revisions. The most compatible versions are those with Hi3798M v200 chips and eMMC storage. NAND flash versions are trickier due to bad block management.
Open the EC6108V9 case (use a spudger; the clips are fragile). Look for a 4-pin header labeled J15, J16, or TX/RX/GND/VCC. If it isn't populated, you will need to solder wires.
Connect your USB-to-TTL adapter:
Open a serial console (PuTTY, screen, or minicom) at 115200 baud, 8N1. Power on the box. You should see bootlog text.
