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

  1. Building from source: branch apjet01-802.11n is probably what you want as it is the only one with qcn5502 support
  2. Using unofficial images (NO WARRANTY! BACK UP YOUR FLASH!)
    1. 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”)
    2. checkout the apjet01-releases/v1 tag and look inside asus-apjet01-releases directory
    3. select the file depending on the name (and version!) of your device
    4. *squashfs-factory.bin is 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.

  1. Connect router's LAN port to your computer
  2. Set static IP of computer to
  3. Make sure the router is turned off
  4. Hold the reset button
  5. Turn the router on and keep holding the button a few seconds until you see the power LED blinking slowly
  6. Use a tftp client to send the image file to IP at port 69 (example with atftp: atftp --put -l /path/to/image 69)
  7. If there are no errors from tftp client, bootloader is installing OpenWrt; wait 2-3 minutes
  8. Remove static IP from your computer's network interface, switch back to DHCP

Another updated custom build, with package management working:

partition start end Name
mtd0 0x000000000000 0x000000040000 Bootloader
mtd1 0x000000040000 0x000000050000 nvram
mtd2 0x000000050000 0x000000060000 Factory
mtd3 0x000000060000 0x000000f80000 linux
mtd4 0x0000001ecb00 0x000000f80000 rootfs
mtd5 0x000000f80000 0x000001000000 jffs2
mtd6 0x000000000000 0x000001000000 ALL

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
