Installation:
Please check the Wiki for this device for a more convenient solution than the one below.

1. Disassemble the device, desolder and dump the flash chip with a SPI programmer.
2. Separate the partitions with dd:

dd if=spi_dump.bin of=u-boot.bin     bs=1  skip=0        count=196608  status=progress
dd if=spi_dump.bin of=u-boot-env.bin bs=1  skip=196608   count=65536   status=progress
dd if=spi_dump.bin of=factory.bin    bs=1  skip=262144   count=65536   status=progress
dd if=spi_dump.bin of=firmware.bin   bs=1  skip=327680   count=7995392 status=progress
dd if=spi_dump.bin of=bdinfo.bin     bs=1  skip=8323072   count=65536   status=progress

3. Download the sysupgrade firmware at openwrt.bin.
4. The firmware size should be 7995392 bytes. Fix the size of your firmware putting zeros to the end, with:

truncate -s 7995392 firmware.bin

5. Combine all the parititions:

cat u-boot.bin u-boot-env.bin factory.bin openwrt.bin bdinfo.bin > spi_new.bin

6. Erase and flash the SPI chip with the new file. Solder the chip and boot the router.
