worksforme!! Very Happy

Boot log looks normal now, I went ahead and burnt the proper rf mac's while I was in there.

I have to say, that was fun and great for learning, I hope i don't have to do it again anytime soon. Smile

I find myself in a similar situation... I have read all the posts (really). I'm greener around the gills than Dark_Shadow, but I am capable or changing mac, running a tftp daemon, ect. Can you guys help me out a little by consolidating the necessary steps that were taken in the order to take them? Question

Sure, can you give some details about your brick? What happened?

And what is the current status of the router and what have you tried so far.

I first flash DD-WRT, and found that wireless N could not be detected.

So I mtd erase linux partition. Use tftp to upload original netgear chk.

Back to netgear firmware, the MAC address are all wrong, 00FFFF FFFFFF and 00FFFF FFFFFE.

So I use /sbin/bd* to write back serial, model and mac address.

But still can not flash any chk from web.


Then I do a 'erase linux'


After reboot, I can only get to tftp.

But no matter what I upload, it seems not being flashed..

So which other 3rd party firmware was on the router when you flashed it to dd-wrt?

The router upgrade to WNDR3300_V1.0.45_1.0.45 at first launch.

Then DDWRT dd-wrt.v24_std-wndr3300.chk from router database, initial.

Then back to WNDR3300_V1.0.45_1.0.45.

Thank you~

Ok, I was only trying to understand how this could happen since dd-wrt does not have access to the factory board data partition that has been trashed.
The linux partition ends before the factory board data so mtd erase linux can not erase board data.

The solution how to fix it is likely to be found in this thread so read it from the beginning and follow Dark_Shadow's steps.

The strange thing is, after DD-WRT to original firmware, the board data is already broken. Wrong MAC address, and does not accept firmware upgrade from web.

Sad Sad Sad Sad

already looking for Nokia cable to serial connect it..

are there any CFE boot loader that support telnet and can replace stock boot loader?

hmm, I don't understand how it happened, it is the symptom of a too big file being loaded but the dd-wrt .chk file should be within limit. A std-generic dd-wrt firmware is too big though.

There is no CFE with telnet support, terminal session is only available through the serial port so you'll have to wait for your USB<-> Serial TTL cable to arrive.

I've been doing a lot of research on the safest and best way to revert this router. I need to revert one.

If you search through the piles of threads & mountains of information, It looks to me that the trashing of the board data partition is fairly common. Many posts of serial outputs in which the macs are all ff's.

I don't know if it happens when dd-wrt is installed, upgraded, or when the unit is reverted.

What about the Netgear Recovery Utility?

http://www.dd-wrt.com/phpBB2/viewtopic.php?p=459998#459998

Seems to me that it is a much safer way to do a revert than the general tftp method.
