Restoring original Buffalo firmware

[Clive Backham]

I have just bought a Buffalo WHR-HP-54 router, and am interested in
trying out the Tomato firmware for it. However, there is this warning
in the Tomato readme file:

"WARNING: Be aware that Buffalo only has encrypted firmwares on their
web site. You will not be able to revert the router's firmware back to
Buffalo's without an unecrypted version of their firmware."

Unfortunately there seems to be no additional advice regarding what to
do about this. I am concerned that if my attempt to install Tomato
fails, or if I don't like it, I make end up unable to revert. Is there
anywhere with some more information about how to restore original
Buffalo firmware?

I believe you may find a link to one decrypted version of
the Buffalo HP firmware somewhere on the DD-WRT site. It
doesn't have to be the latest, just something that works
well enough to flash the firmware again with the lastest
version from the Buffalo site.

However, I wasn't able to locate anyone who had actually
done this. In the end, I just left the stock firmware
alone. The only thing it does that isn't so great is that
it drops everything when it renews it's lease from Cox at
the mid-point (12 hours). It either doesn't wait long
enough to get a response from the DHS server, or it can't
find the same one it used to get the lease originally, or
something, but the log confirms that about half the time
instead of a seamless renewal, it drops everything and
negotiates a new lease. Of course everything online at the
time is cut off, and has to recover. I don't know why it's
so all-fired insistant to do the renewal - it could wait
till the 3/4 point, or even later. But no.

Anyway, it's no huge deal. So, I just let it be. But if I
ever need any of the more advanced functions, I would
probably do DD-WRT. I don't know anything about Tomato.

Good luck.

How to recover from a bad flash on various Buffalo routers:
<http://www.dd-wrt.com/wiki/index.php/Recover_from_a_Bad_Flash#Buffalo_WHR-G54S_and_Buffalo_WHR-HP-G54>

I've never had to go back to original firmware on a Buffalo router, so
I've never tried any of the recommended procedures. However, I have
read somewhere that the only reliable way to revert is to use the TFTP
method, which takes a bit of skill and some timing practice. Frankly,
I've never seen the need to switch back to the original firmware,
although I've jumped between OpenWRT and DD-WRT many times, and
bricked the router a few times. Incidentally, the way I've bricked
various devices during the flash procedure is to start tinkering
prematurely. When the screen says it's ready, it's usually too soon.
When you upload a new flash image, just go away and do something else
for perhaps 5 minutes to be sure it's really done.

See:
<http://www.dd-wrt.com/wiki/index.php/Installation#Buffalo>
for the installation instructions which include something on TFTP.

The above article recommends you search the DD-WRT Forums for
"WHR-G54S bricked". There are enough debricking threads, you don't
need to start your own.

The article also includes this suggestion:
Once you flash to DD-WRT on the Buffalo
WHR-G54S/WHR-HP-G54/WZR-RS-G54 and you, for whatever reason,
want to flash back to the Buffalo firmware, look in the
downloads section of dd-wrt.com in the "buffalo factory revert"
folder for unencrypted firmware that will load from the DD-WRT
gui. The WHR-HP-G54 image is the German version. Download the
English version from Buffalo's site. Flash the German version
and use that to flash the English version.
The files mentioned are buried here:

Yes, revert to DD-WRT. :)

Thanks to everyone for their comments.

Seems like most people are recommending DD-WRT rather than Tomato. I
did briefly compare the two firmwares and it seemed to me that Tomato
offers the features I need in a fairly friendly-looking package, while
DD-WRT looks aimed more at the serious networking specialist.

Anyhow, I tried flashing with Tomato and TFTP kept saying "Timeout
Occurred", so for now I'm still on the Buffalo firmware (and the
router seems to be working well). I'll probably try DD-WRT next.

Give the computer a static adress.
and connect direct to the routers lan port
and ping the router to se connect.


Static add
ip =192.168.1.2
mask 255.255.255.1
gate away 192.168.1.1 (router lan adress)


reboot comp and bring the router in recovery mode if you can
then go to start > run cmd to get consol mode
type tftp -i 192.168.1.1 PUT (the firmware name) enter.

Hope it's work

Multiple methods here:

Follow the DD-WRT instructions carefully and get that on there first.
Then flash within the interface to Tomato. That should work.

Let us know how you like Tomato. Many people who don't need DD-WRT's
extensive feature set recommend Tomato for good bandwidth monitoring,
quality of service and as being very stable.
