Moving drom DD-WRT to OpenWRT

Hi Everyone,

I have a couple of WL500gPs (v1) that have been running dd-wrt for about 4-5 years but I want to move them to OpenWrt to use them with worldspot.net's hotspot service (some features are not available if using dd-wrt due to the age of some installed apps).

What's the best process to follow for this - from what I have read in the wiki and elsewhere, the following is OK:

Code:

---

cd /tmp/
wget [link to image]
mtd -r write /tmp/[image].trx linux  (having verified the target folder name)

---

Also, any specific comments on which firmware version and type to use (backfire, attitude..etc.) - I understand I need the brcm47xx variant.

Any relevant advice would be appreciated.

Thanks
