WNR2000v1 owners, I'm working on building new images for you.

Stay tuned..

Took out my old WNR2000 and look OpenWRT is available now for it. And look someone said something about new image for it .... damn I am lucky.


1 question if possible. I just have STOCK V1.2.3.7NA firmware and I do have TELNET activated so I can go in and stuff. So my next step is wait for your image or I need to do before something. Link to instructions if possible.

Thank you ! And amazing that people still work on this.

Couldn't wait had to install what I had using

<code>
cd /tmp
snarf http://fuhry.co.cc/b/wnr2000/ubootenv-s … itions.img
snarf http://fuhry.co.cc/b/wnr2000/u-boot.bin
snarf http://downloads.openwrt.org/backfire/1 … uashfs.bin

mtd -e mtd0 write u-boot.bin mtd0
mtd -e mtd1 write ubootenv-stockpartitions.img mtd1
mtd -e mtd2 write openwrt-ar71xx-ap81-rootfs-squashfs.bin mtd2
mtd -e mtd4 write openwrt-ar71xx-uImage-lzma.bin mtd4
reboot
</code>

Worked like a charm. I did see I had only 170 kb or so and I had to damn try to install something ..... what an idiot.... anyhow I was trying to install bmon to "monitor" stuff and abviosly it didn't because of lack of space, but now I have only 8kb left. Guys .. anyone know how to cleanup bad install ?

HEre is what happened

I am looking at Overview page and it looks like it's not hopeless afterall. I See total available is only 67% full , so I guess some memory allocated for software that could be installed and another for system criticall files and Linux Kernal.

2 LAst questions guys. I See I have OpenWrt Backfire 10.03.1 / LuCI 0.10.0 Release (0.10.0) and it looks like 12 is latest version. IS there a quick upgrade available or hwo do I update it to the latest version, and second question is there a way to upgrade memory ? I have WNDR3700v1 and with that router it's easy, stick 1TB in the back usb slot and you're set, with this one I need to do something else .....

Thanks guys I'd really appreciate on that software debris thing help.

I'm new to this forum but I have flashed similar firmware on a wrt54g several times. I have a WNR2000 v1 and would like to flash openwrt. Can this be done with tftp now?

No, but it's not much more difficult than using tftp.  See the instructions in previous pages.

YAY /cheer !

Now let's see if I can flash it without breaking anything .......again.

I have read through every post and I'm unclear on what to download to load onto the router. People reference the newest build of attitude adjuster but there's many versions in the downloads section. I am aware that you have to telnet into the router and use commands, but the problem is there doesn't seem to be one way to do it. I'm confused...

Follow the instructions on post #161.  The links to the files are functioning as I just checked.  Those are the commands you need to copy/paste in telnet.

I use putty for telnet but you can use whatever you prefer.  But you have to make the router "telnet-enable" first.  Google "enable netgear telnet".

It's as simple as just copying/pasting the following in the telnetEnable.exe cmd file: telnetEnable 192.168.1.1 "yourroutermacaddress" Gearguy Geardog

The links in the post #161 are for the backfire builds.  If you want the attitude adjustment, change the links for ar71xx-ap81 files.

I think I messed up...I was able to enable telnet, then I copy and pasted the command into telnet...

I did this while wired directly to the router with wifi off.

I then waited for it to reboot and no lights came on. After a minute, I unplugged it and plugged it back in and pushed the on button, still no lights sad

Did I brick?

Maybe.  Are you sure you have WNR2000 V1? Not any other version?  Go through the posts and you'll find ways to revert it back to stock.

I did research and on the back of the router if it was v2 3 or 4 it would say, mine just says WNR2000. It was bought when they first came out too so.

It doesn't even turn on. So I fear the only way to revive is through a jtag.

You can find out about the version based on the router's FCC ID.  http://wiki.openwrt.org/toh/netgear/wnr2000

Also, there's sticker on the board that indicates the hardware version (remove the stand, unscrew and slide the side panels out).

USB-serial would be more convenient instead of jtag.  I can't tell you what you did wrong but good luck.

Welp I think I bricked my v1 router as well trying to revert to stock by accessing ssh, and running the listed commands

mtd erase u-boot-env
mtd erase uImage
reboot

I think tried to tftp flash, but I never got a ping response at all from the router no matter what I tried, even using arp. It just booted up with a solid power light, and lit up whatever port I connected to. However, it was inaccessible. I tried holding factory restore, which someone suggested, but this did not help, not providing a ping at all, but now the power button blinks.

I am trying to figure out how to use a serial cable to debrick the router - not the connecting part, but what do I do with the connection?

Once the serial connection is made, hit any key to stop the booting process, & type the following:

mtdparts default
erase nor0,4
erase nor0,1

Then reboot, set local ip to 192.168.1.x, & flash to stock firmware via tftp.

I have tried using a usb to serial cable and have the cable connected but when I power on the router the light comes on a split second then shuts off. Has anyone had this issue? I've tried googling and nothing seems to come up sad

Hello, Guys and thank you for great works.

I have a stupid question.

Is there any way to re-flash u-boot instead of re-soldering?

Recently, I ran the following command in order to fetch u-boot

snarf http://www.simcop2387.info/wnr2000/u-boot.bin

and I think at that time I didn't have internet connection and snarf created a 0byte u-boot.bin
file. Damn snarf!
I didn't know this and flashed it to mtd0. LoL

My router is WNR2000v1 and doesn't have JTAG port (according to http://wiki.openwrt.org/toh/netgear/wnr2000 ) but it seems to have the port-out.

Anyone experience this?

Cheers,

enddl22, maybe the pin short method would work to recover your firmware. 

Be careful, though.   I never tried it on a WNR2000v1.

Could anyone tell me how to restore to the stock firmware my WNR2000v1  ?  thanks

Done as you said but now my router is bricked. Even if I push the reset button while turning it ON to activate the TFTP recovery mode wating until it starts to blinks green slowly, I can't ping any other device than my laptop (192.168.1.2) so I can't upload via tftp the stock firmware

any idea?

Exactly the same here, someone told me to follow the post #202 on page 9, now my router boots up bliks slowly green and there's no ping at all

did you find a solution to this problem without using serial jtag ?

DONT'T FOLLOW THE POST #202 on page 9 to revert to STOCK FIRMWARE I JUST BRICKED MY ROUTER AS ANOTHER USER IN THIS THREAD


THANKS

When using TFTP and router in recovery mode I'd be surpriced if router pings or provide IP at all. With all Netgear ( I just did it with 3700v1) I manually set my IP to 192.168.1.10 and flash with TFTP, using router IP as 192.168.1.1 even if router have no IP at all at the moment.

Thanks but I tried to TFTP the stock firmware and I got a timout  error, even seems that I'm able to connect to any TFTP adress (192.168.1.X)  once the router is in TFTP mode but none of them is able to receive correctly the router firmware

do you have any suggestion ?
