====== TP-Link TL-WR703N 刷DDWRT,OpenWRT======

===== 在DDWRT基础上刷OpenWRT =====

USE THESE INSTRUCTIONS AT YOUR OWN RISK

I have only done this procedure once and sharing because of the lack of information on the web on how to do this.

Some of the sellers of the TL-WR703N are shipping the routers with DD-WRT pre-installed – some with a Chinese interface, some with an English interface.

Regardless, you need telnet or SSH access to the router as upgrading via the web interface will not work.

==== Step 1 : ====

Get the OpenWRT image onto the router.
e.g.
<code>
root@DD-WRT:/tmp# wget http://192.168.1.142/openwrt/ar71xx/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin
Connecting to 192.168.1.142 (192.168.1.142:80)
openwrt-ar71xx-gener 100% |*******************************| 3840k 0:00:00 ETA
</code>

Other methods can be found here :- http://wiki.openwrt.org/doc/howto/generic.sysupgrade

==== Step 2 : ====

The TRICK is that the partition names are different between OpenWRT and DD-WRT.  Whereas all OpenWRT instructions will tell you to write to the ‘firmware‘ partition, this does not exist on DD-WRT and you have to use the ‘linux‘ partition instead.  Use the ‘mtd’ command as per the example below to write the OpenWRT image onto the router.  Note the ‘-r’ argument will reboot the router as soon as the flash is complete.  (As usual, do not power off or disconnect during the flashing!).

<code>
root@DD-WRT:/tmp# mtd -r write openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin linux
