Hi,

some months ago I  installed with success OpenWrt on my Netgear DG834g v2, like explaned on this page http://wiki.openwrt.org/toh/netgear/dg834g

Now, I need to reinstall the original firmware !

That's the system actually installed:

root@OpenWrt:~# uname -a
Linux OpenWrt 2.6.32.10 #21 Tue Apr 6 14:55:04 CEST 2010 mips GNU/Linux

and that's the actual mtd layout on the router:

root@OpenWrt:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00010000 00002000 "loader"
mtd1: 00010000 00010000 "config"
mtd2: 003d0000 00010000 "linux"
mtd3: 002f0000 00010000 "rootfs"
mtd4: 00140000 00010000 "rootfs_data"

And those are the mtd's saved on my pc before to install openwrt (obtained with dd if=/dev/mtdblock/N of=/tmp/mtdN.bin ):

root@lordeb:/home/lorenzo/netgear# ls -al mtd*
-rw-r--r-- 1 lorenzo root    3211264  8 set  2002 mtd0.bin
-rw-r--r-- 1 lorenzo root     720896  8 set  2002 mtd1.bin
-rw-r--r-- 1 lorenzo root     131072  8 set  2002 mtd2.bin
-rw-r--r-- 1 lorenzo root      65536  8 set  2002 mtd3.bin
-rw-r--r-- 1 lorenzo root      65536  8 set  2002 mtd4.bin

How can I restore those mtd and get back the original system?

PS: I tried to enter via ADAM2 ftp server, but it seems to be not longer present !

Thanks in advance
Lorenzo

Can't you just use that? I have no clue about this router.. but can't that recovery be used to flash original firmware?

Hi Boompje123, thanks for your reply!

I would to try but :

"The image file is expected to be in the official firmware format, which I think is mtd2+mtd1+mtd0 concatenated."

I have those mtd0.bin .. mtd4.bin, how can I concatenate 2+1+0 ? And what about mtd3 and mtd4?

Other option: I downloaded from netgear website the last firmware for my router, but is .img instead of .bin ( all guides that i've seen used to flash a .bin )

Does Netgear's recovery utility expect bin as well?

Netgear utility cant communicate with Netgear, ntp2 too.

Other ideas?

However, sports performance analytics tools which use localisation or "tracking" technologies, such as GPS (which has minimal accuracy and precision), COPS (Centimetric Outdoor Precision System) and other positioning solutions are of the most dynamic and widely applicable on the market. As a result of monitoring each athlete's position continually, a wide range of information can be compiled, resulting in unique and varied insightthorinto game dynamics. The info is reliable and is often accurate up to the centimeter. Examination can be performed and assessed in real-time. Localisation doesn't simply capture the highlights. Sports performance analysis tools that utilize hyper-precise localisation technology are uniquely advantageous as they keep track of several KPIs for all athletes throughout the whole practice, training session or game.

Hi lorenzoasr,

Did you manage to restore your router to original firmware?  I installed OpenWRT last night, but can't get my internet connection to work, the interface is really slow and getting timeout issues.
