Sitecom WL-351

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

→ Install OpenWrt (generic explanation)

Currently installing OpenWrt requires you to access the bootloader using the serial port (3.3V level converter required). Set up your server to serve the firmware image (openwrt-ramips-rt305x-wl-351-squashfs-sysupgrade.bin) using tftp.

NOTE: Rename it to a shorter name (or use a symlink), the bootloader truncates the filename to 50 characters!

Hit '2' after it shows “Board: Ralink APSoC DRAM: 32 MB 2*16 MB”, followed by 'y', IP for the device, IP for the server, tftp filename. The file will be transferred, flashed and booted automatically. Congratulations, you are now running OpenWrt! (Using '4' instead of '2' you can enter the uboot prompt)

Notes

The original firmware image WL-351_fw1.5.zip contains two files: WL-351-APPS-V1-5-0-7.dlf
WL-351-KNL-V1-5-0-7.dlf

These are prefixed by 0x60 bytes header and the remainder is xor-obfuscated using the following key: 

0x78,0x3c,0x9e,0xcf,0x67,0xb3,0x59,0xac,0x78,0x3c,0x9e,0xcf,0x67,0xb3,0x59,0xac
