Hi i am hoping to be able to put open-wrt on a buffalo WZR-300HP.
I am not very technically inclined however i do know enough to wreck something.
I was wondering if there is a openwrt version that can go on this router? by simply doing a "firmware upgrade" from the webgui.

I have this one download:
             openwrt-ar71xx-generic-wzr-hp-g300nh2-squashfs-tftp.bin

However when i trade to do a firmware upgrade, it said it was sucessful however the origanal firmware remained and i could not telnet to 192.168.1.1. only 192.168.11.1 (dd-wrt router router default). Which mean it was not sucessful.

I tried reading the wiki but found it a little confusing and it made me kind of nervous for fear of bricking my device.

Any and all help would be appreciated!

Hi.  Wanted to let folks know that I tried to install OpenWrt (attitude adjustment, pulled from nightly build section on 16 November 2013) on a WZR-300HP, revision B0A1. Seems that I bricked it. I first tried to load the image via TFTP.  Despite trying several times with and without a switch, I couldn't get that to work.  I eventually used the MTD method; I was able to telnet into the router with the stock firmware. The MTD method seemed to work until I rebooted, then it was a brick.  I plan to open the case on this thing to see what I can learn from its innards, and how it might be different from the B0A0, which I understand will work.

I'm in the exact same boat. Did you have any progress?

Not much yet.  Got the cover off and am planning on attaching a serial cable. Markings on the board are a little different than earlier models.

PCB is marked:
WZR-HP-G302HV2
21514 W302HV21A3 Rev:A3

To get off the cover, you need a T10 "tamper proof" torx bit, the kind with the little hole in the center.

Same markings on mine; i was able to recover mine back to the stock dd-wrt firmware today without having to serial port the router.

Just picked one of these up.  This is my 3rd one and they are all different revisions lol.

Its good that it flashed back to stock keyboardgnome. 

beckolamuffin are you actually adding the port so you can see what failed in the boot process; maybe driver issue or something?  Interested in seeing that output and please update this thread on any progress.

Two tricks:
First trick was not using windows or the linksys util, but linux and tftp. In windows, it would get up to, oh, about 70-75 percent reflashed, then bomb out. In linux, smooth and silk. (http://g300nh.blogspot.com/2010/06/firm … overy.html)

Second trick was making sure that the switch for router mode (auto/on/off) was set to ON, and not the others.

Here's the obligatory bootlog on the new one

I got it to boot using the tftp in linux and the latest beta firmware. The red diagnostic LED will flash, but it's booted.

by beta I assume that you mean Openwrt trunk? more specifically, http://downloads.openwrt.org/snapshots/ … s-tftp.bin ?

These are the steps I do right after flashing trunk to make configuration easier, in case you might find this useful.  I assume this is still applicable since my last upgrade some months ago:

## POST FIRMWARE UPGRADE FIXUPS
opkg update
opkg install luci
ln -s  /etc/init.d/uhttpd /etc/rc.d/S50uhttpd
/etc/init.d/uhttpd start

in luci i think there's a section regading LED configuration (IIRC)

@keyboardgnome Do you mind updating the thread on what you've achieved so far?

I also picked up one of these WZR-300HP routers and got revision B0A1.  I flashed the trunk build (revision 38999).  I then applied your "Post Firmware Upgrade Fixups" and it all seems to be working for me.  It still detects it as a WZR-HP-G300NH2 but I am not sure how you could tell the difference between them in software yet.

Yes, I want to put on the serial port to find out what is going on, and wrong, with the boot process.  I am also hoping I can coax the boot loader into loading a different firmware image.  I just got the parts I needed today from DigiKey.  I hope to do the soldering sometime this weekend.  I will report back.

Hi

I have a Buffalo wzr-300hp BO A1

I first tried openwrt-ar71xx-generic-wzr-hp-g300nh-squashfs-tftp.bin - but that was a mistake - it paniced

Then I tried to flash
http://downloads.openwrt.org/snapshots/ … s-tftp.bin

and it seems to work, I get this result on the serial console:

Cool!

Thanks for posting!  How did you flash it?  Using TFTP?  If so, what operating procedure?

Thanks!

I flashed it from dd-wrt

cd /tmp
wget http://downloads.openwrt.org/snapshots/ … s-tftp.bin
mtd -r write openwrt-ar71xx-generic-wzr-hp-g300nh2-squashfs-tftp.bin linux

/Peter

Was curious about different model references in the code.  I haven't custom rolled openwrt before.

for file in `find . -type f`; do if [ $(grep -c WZR-HP-G300NH2 $file) -gt 0 ]; then echo $file; grep -c WZR-HP-G300NH2 $file; fi; done

Lorenzen do you mind posting your `cat /proc/cpuinfo` while booted on openwrt?

Here is openwrt_release, cpuinfo and u-boot-env

At long last, I was able to put on a serial header to my WZR-300HP, revision B0A1, that I thought I bricked. I had loaded Attitude Adjustment 12.09 via the MTD flash method, and it quit working.  Here is the serial console output:

I was able to flash openwrt-ar71xx-generic-wzr-hp-g300nh2-squashfs-tftp.bin from Barrier Breaker's snapshot directory (25 January 2014 {OpenWrt Barrier Breaker r39382 / LuCI Trunk (svn-r9951) }).  The flash was accomplished using TFTP.  Note that I used the LAN port furthest away from the WAN port to accomplish this.

I used the following settings on my Linux desktop (the TFTP server).

ifconfig em1: 192.168.11.2
arp -s 192.168.11.1 02:aa:bb:cc:dd:1a
tftp -m binary 192.168.11.1 -c put openwrt-ar71xx-generic-wzr-hp-g300nh2-squashfs-tftp.bin

Note that when setting up the serial terminal, I did the following:
*Soldered on a 4 pin header;
*Attached a cell phone data cable, in this case an old Radio Shack "Mobile Phone Data Cable, Cable 22" (part number 170-0762){might not be available any more};
*Connected pin 1 (VCC +3.3v) {left hand side pin, where all ethernet and USB ports are on the left} to nothing;
*Connected pin 2 (GND) to green;
*Connected pin 3 (TX) to white;
*Connected pin 4 (RX) to orange;

I did not have to short any resistors.

I was able to install the stable version of barrier breaker on this rig.

Note that I had best success using minicom on the serial port with hardware and software flow control both set to 'yes'.

Also, the Linux laptop is the tftp client. I misspoke in the previous post.

trunk (chaos calmer) is listed as supporting this model which i interpret as initial support given hardware variances are not known and also implies using the wzr-hp-g300nh2 image.  i installed trunk on the older wzr-hp-g300nh (no 2) variant tonight and it is running well so far.

at some point i may try the mtd flash method if things seems safe.  i really don't want to do the serial port mod.
