Installing OpenWrt
NOTE! There is no official support at this point. The following link leads to an unofficial, personal repository where the development is taking place.
You can download the WIP source code and community images at https://gitlab.com/alexconst.sh/openwrt.
- Building from source: branch apjet01-802.11n is probably what you want as it is the only one with qcn5502 support
- Using unofficial images (NO WARRANTY! BACK UP YOUR FLASH!)
- make sure your stock flash layout matches the table under the “Flash Layout” section below on this page (rootfs doesn't matter as long as it's contained inside “linux”)
- checkout the
apjet01-releases/v1tag and look insideasus-apjet01-releasesdirectory - select the file depending on the name (and version!) of your device
*squashfs-factory.binis what you want for full initial install
In recovery mode, the bootloader will start a tftp server and wait for you to send the image.
- Connect router's LAN port to your computer
- Set static IP of computer to
192.168.1.10/24 - Make sure the router is turned off
- Hold the reset button
- Turn the router on and keep holding the button a few seconds until you see the power LED blinking slowly
- Use a tftp client to send the image file to IP 192.168.1.1 at port 69 (example with atftp:
atftp --put -l /path/to/image 192.168.1.1 69) - If there are no errors from tftp client, bootloader is installing OpenWrt; wait 2-3 minutes
- Remove static IP from your computer's network interface, switch back to DHCP
Another updated custom build, with package management working: https://github.com/looi/openwrt/releases/tag/qcn550x-tag

You can backup a partition like this:
- Login via ssh, telnet or serial console
- Use dd command to backup (Danger, wrong usage can overwrite rom):
dd if=/dev/mtd6 of=all.img - Use scp to download the image
