any ideas how I could get from openwrt back to dd-wrt (or buffalo original fw)? i was testing the build 20453 and bricked my wbmr, only way to get it back running was to install openwrt via using firmware.ram upload over tftp...

neither dd-wrt or buffalo stock firmwares can be flashed using bootloader requesting firmware.ram from tftp server -method. or have i understood something wrong?

After the brick you have to flash a openwrt image by sftp ramdisc method
http://wiki.openwrt.org/toh/buffalo/wbmr-hp-g300h
(How to recover from bricking) you must join
wiki.openwrt.org/_media/toh/buffalo/openwrt-lantiq-ar9-wbmr-uimage.tar00.zip and wiki.openwrt.org/_media/toh/buffalo/openwrt-lantiq-ar9-wbmr-uimage.tar01.zip to get firmawe.ram , once you have openwrt recovery you have to flash the file webflash truncada.bin in openwrt gui (its simply a cutted version of a previus webflah firmware).

it should work if you follow the instructions in this thread. make sure that your firewall is off.

Problem was in the power on with aoss pushed. When I switched off the power my MAC was shutting down the ethernet interface and the time to set it up when the router power is on seems to be too long with respect to the tftp request. I solved by changing computer...

Hello


from (k24043) thanks to him

------
follow th instructions in http://tuananh.us/2012/12/05/how-to-debrick-buffalo-wbmr-hp-g300h/

for that you need pc with ip-address 192.168.11.2 running TFTP server and all firewalls off

then buffalo runs openwrt and you can install below pacakge and it is back to dd-wrt.

Then I would do a full reset and install some of the 19xxx builds

Download this file ftp://dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2013/01-24-2013-r20548/buffalo_wbmr_g300nh/uImage.bin

And HFS (for send file to router) http://www.rejetto.com/hfs/

Follow instruction in this page http://wiki.openwrt.org/toh/buffalo/wbmr-hp-g300h#how.to.recover.from.bricking

After your router is booted.
- Change your computer IP Address from 192.168.11.2 to auto (DHCP). And wait for new IP.
- Start HFS and add file uImage.bin to root.
- Telnet to router 192.168.1.1, chdir to /tmp
- wget http://[Computer IP]/uImage.bin
- Flash new image "mtd -r write uImage.bin linux".
- Wait for router reboot.

Your router is now DD-Wrt r20548.

thanks a lot guys...i have successfully unbricked mine.

just for anyone else wants to go through this process:

i followed this guide
http://tuananh.us/2012/12/05/how-to-debrick-buffalo-wbmr-hp-g300h/
all the way to step 5, and then i followed joei007 instructions.

After step 5 you should not reboot the rooter, even if there are no lights (mine's power light went off)

also at the step where you have: wget http://[Computer IP]/uImage.bin do not forget to add the port as well as shown at the HFS file. for example mine was
wget http://192.168.1.161/8080/uImage.bin

thanks again
