in order for me to flash firmware.uimage i had to hook up serial to interrupt the boot up process. every time i flashed firmware-us.bin i use the Buffalo UI. the buffalo UI would not take firmware.uimage it would give me an error message saying "invalid firmware"
When i didnt have the serial connection the only way to restore the router to factory is to hold a AOSS button infront of the router so that it can start to look for a file called "firmware_WHR-600D.ram" which is stock buffalo firmware. at one point i did try to rename firmware.uimage to firmware_WHR-600D.ram but it didnot like that.
since i got the adapter now i was able to flash firmware.uimage r43516 thru the serial terminal however i get the same result
ill keep an eye on it for the next few days and report any issue i encounter.
Some thing Ive notices on virtual all builds, When i used routers as access points. Ill disable Wan, set a static IP,Assign WAN Port to Switch, and set dhcp forwarder to my main router. the time settings will not update the time on the router. ive tried adding different ntp server. enable/dissable NTP Client.
the only way it updates the time is if i use as a router.
Not major just something i saw.
