Linksys WRT54G v7.2

WRT54G v7.2 units presumably have serial numbers prefixed with CDFK.

"3763-14141905R" is silkscreened on the board according to the picture on TechInfoDepot below. This is the same board ID as the Linksys WRT54G 8.0.

WRT54G v7.2


 * 1) Reset the router to defaults on the Linksys Admin page, and let it reboot or manually reboot it after its finished.
 * 2) go to the firmware upgrade page and browse to the VxWorksPrep-Gv72-v1.bin file and click on the upgrade page. Wait for 30 seconds for it to reboot on its own, if it does not then powercycle the router manually.
 * 3) again go to the firmware upgrade page and browse to the VxWorksKiller-Gv72-v3.bin file and click on the upgrade page. Wait for 60 seconds for it to reboot on its own, if it does not then powercycle the router manually.
 * 4) Tftp the DD-WRT firmware to the router dd-wrt.v24_micro_generic.bin, after successful tftp, wait 3 min for the router to finish writing new nvram defaults, etc... It should reboot on it's own at least two times, so give it the three min's and then goto http://192.168.1.1
 * 5) Check for recommended builds here.

Reverting to OEM Firmware from DD-WRT

 * 1) Reset to defaults
 * 2) goto the Admin screen firmware upgrade, and browse to VxWorksRevert-Gv72-v3.bin and click upgrade. During this time the Web browser may say upgrade successful and to reboot -"Do NOT REBOOT"- Wait for 2 min's and then reboot.
 * 3) Go to http://192.168.1.1 and you should see a mgmt mode screen, this is where you browse to the original Linksys Firmware, and and upgrade.
 * 4) Wait for 1 min, even if it say's upgrade successful and to reboot, believe me, in my tests, it has not finished yet.
 * 5) go to http://192.168.1.1 - you should have the regular Linksys Firmware.

DD-WRT Notes
It may be necessary to completely close and reopen the browser, it sometimes will return to a mgmt screen, if you only refresh the browser after upgrading, just close the browser and try again.
