Flash instruction using initramfs-factory.bin image (StockFW WebUI):
1. Boot WG1800HP with router mode normally
2. Access to the WebUI ("http://aterm.me/" or "http://192.168.0.1/") on
the device and open firmware update page ("ファームウェア更新")
3. Downgrade the stock firmware to v1.0.2
4. After downgrading, select the OpenWrt initramfs-factory.bin image and
click update ("更新") button
5. After updating, the device will be rebooted and booted with OpenWrt
initramfs image
6. On the initramfs image, upload (or download) uboot.bin and
sysupgrade.bin image to the device
7. Replace the bootloader with a uboot.bin image
mtd write <uboot.bin image> bootloader
8. Perform sysupgrade with a sysupgrade.bin image
sysupgrade <sysupgrade image>
9. Wait ~120 seconds to complete flashing
Flash instruction using initramfs-factory.bin image (bootloader CLI):
1. Connect and open serial console
2. Power on WG1800HP and interrupt bootloader by ESC key
3. Login to the bootloader CLI with a password "chiron"
4. Start TFTP server by "tftpd" command
5. Upload initramfs-factory.bin via tftp from your computer
example (Windows): tftp -i 192.168.0.1 PUT initramfs-factory.bin
6. Boot initramfs image by "boot" command
7. On the initramfs image, back up the stock bootloader and firmware if
needed
8. Upload (or download) uboot.bin and sysupgrade.bin image to the device
9. Replace the bootloader with a uboot.bin image
10. Perform sysupgrade with a sysupgrade.bin image
11. Wait ~120 seconds to complete flashing
Notes:
- All LEDs are connected to the TI TCA6416A (marking: PH416A) I2C
Expander chip.
- The stock bootloader requires an unknown filesystem on firmware area
in the flash. Booting of OpenWrt from that filesystem cannot be
handled, so the bootloader needs to be replaced to mainline U-Boot
before OpenWrt installation.
- The data length of blocks in firmware image will be checked
(4M < threshold < 6M) on the stock WebUI on some versions (v1.0.28,
v1.0.30(latest), ...), so needs to be downgraded before OpenWrt
installation with initramfs-factory image.
