Khrys, 

Give Buffalo a call they may be able to help you reflash it via tftp or something. This router takes longer than most to flash new firmware, it'll do that 2 diag blink and appear to just be restarting for quite some time, but you need to be patient and it'll eventually come back up and be fine - bottom line - be patient. I think since you unplugged it during it's update process you'll not be able to flash it again via the normal process....

Thanks mit. My situation is kinda different. I bought the router from a seller in Korea and I am from Brazil. So I am tryin' to solve this without buying another one ><.

 

Thanks for your reply.

 

I found some tutorial using tftp but it didn't work for me... so today I bring the router to my work to get some help from specialists.

 

Thanks again.

I would try holding the reset button for 30 seconds and then waiting two minutes. If that doesnt work then in order to recover the unit a tftp boot would be the only way to recover it. Unfortunetly you cannot transfer the buffalo firmware that way, so you would have to use a 3rd party firmware but it would void your warranty to do that.

I found a tutorial here: http://g300nh.blogspot.com/2010/06/firmware-flash-and-brick-recovery.html so I tought ir might work... My friend will come here today to help me with this tutorial.

 

 

Bottom line: Its sad 'cause I was so confident if the flash process get wrong I could put the firmware in the pendrive, boot up the router and everthing was back to normal... but yeah... I didn't read the manual and i trusted too much in a way I realise it wasn't possible.

 

As I told before, I am from Brazil, this router came from Korea and if I can't recover it... it's a big $$$ loss to me...

 

Thanks again.

The reset process you did was correct. You could try and go to DD-WRT.com and look up their tftp boot process. I got it to work with a WHR HP G54 and thats how I learned to do it. It may work to recover your unit. But again doing this would void your warranty. And that tutorial page linked says page not found. I've never tried to load the firmware from a pen drive but my guess is that it wouldn't work.

I will look at dd-wrt.com, thanks. For the tutorial, please remove the comma at the end of the link. Void the warranty isn't a problem, 'cause to me it's cheaper to buy another hence send it to korea. Thanks again.

That tutorial seems legit. I would give it a try. It looks like it actually came from DD-WRT.com
