The starting address of 'factory' partition is 0x40000, and the
starting address of the next partition is 0x50000. It's obvious
that the correct size for the 'factory' is 0x10000, just like
other MT7620 devices.

Flash by the native uploader in 2 stages:
1. Use the native uploader to flash an initramfs image. Choose
openwrt-ramips-mt7620-snr_cpe-w4n-mt-initramfs-kernel.bin file by
"Administration/Management/Firmware update/Choose File" in vendor's
web interface (ip: 192.168.1.10, login: Admin, password: Admin).
Wait ~160 seconds.
2. Flash a sysupgrade image via the initramfs image. Choose
openwrt-ramips-mt7620-snr_cpe-w4n-mt-squashfs-sysupgrade.bin
file by "System/Backup/Flash Firmware/Flash image..." in
LuCI web interface (ip: 192.168.1.1, login: root, no password).
Wait ~240 seconds.
Flash by U-Boot TFTP method:
1. Configure your PC with IP 192.168.1.131
2. Set up TFTP server and put the
openwrt-ramips-mt7620-snr_cpe-w4n-mt-squashfs-sysupgrade.bin
image on your PC
3. Connect serial port (57600 8N1) and turn on the router.
Then interrupt "U-Boot Boot Menu" by hitting 2 key (select "2:
Load system code then write to Flash via TFTP.").
Press Y key when show "Warning!! Erase Linux in Flash then burn
new one. Are you sure? (Y/N)"
Input device IP (192.168.1.1) ==:192.168.1.1
Input server IP (192.168.1.131) ==:192.168.1.131
Input Linux Kernel filename () ==:
openwrt-ramips-mt7620-snr_cpe-w4n-mt-squashfs-sysupgrade.bin
3. Wait ~120 seconds to complete flashing
