Unable To Extract DD-WRT V24 Build 15778 for TP-Link WR841ND !!! HElp.....

[ifzaal002]

Can Any one tell me what i am missing in the firmware modification kit...
I am using UBUNTU 10.04 and  i want to extract the DD-WRT V24 PRESP2 to add the tcp/ip server file in the router..
Kindly tell me what is missing in the package or any library..Here is the log after running the extraction command..
Thankx in advance.....

[ifzaal002]

It seems no one wants to answer ... OK..
I tried factory-to-ddwrt.bin to extract , it extracted successfully but there was still problem when i tried to rebuild it without any modification to check only that is works or not. It creates the rebuilt files but they are not more than 1Kb(i think no one has still made NANO DD-WRT..... ). Here is the log and the terminal output after executing build_firmware.sh....Help if u can.... Its urgent as i am working on my final year project of BS computer Science... REGARD and THANKX in advance..

Same issues for me.

I'm trying to build a dd-wrt (factory-to-ddwrt.bin) for the tp-link WR741ND.


Scripts are exec as root and build is done for wnr3500L firmwares (NETGEAR)
Generated bins are 1Ko and trx is empty...

What's wrong?

I don't have a quick answer. I have not looked into that firmware. Support could be extended for that platform, there's no doubt about it. It wouldn't take much work, but the issue is that any change to the kit comes with a lot of extra testing and is generally painful. I don't have one of these devices to even test with myself. At this time I am relying on users to help contribute patches to the FMK. I've already added one new commiter/contributor to the project only last week, when he added support for a different firmware type. Anyone who wants to take the time to make the necessary adjustments, feel free.

It is unfortunate DD-WRT frowns upon the entire idea, as they don't like people changing their firmwares (yes, even though it is open source and 99% of it consist of the linux open source kernel). His scripts and web UI additions are apparently very valuable to their bottom line, so they prefer to try to keep control of them. That's another subject though. It just does seem to be a shame that a supposed free open source project is so difficult to tweak.

It would be trivial for them to provide something similar to the FMK, capable of taking their firmware images apart, allowing modification, then reconstructing them. Their precious web UI would still be protected, since the source code isn't distributed so you can't rebuild it. However, they have no interest in providing such.

Don't take it out on me, I'm just a volunteer who wasted a year of my life first hacking the WRT54Gv5 so it could run DD-WRT micro, and in other projects like the FMK. That was the poorest year of my life and I nearly destroyed myself financially as I tried to contribute to the F/OSS world. I still do contribute, but only when I can.

DD-WRT, on the other hands, *profits* from their work. It is not unreasonable for their users to demand such a tool from them. Heck, I think Brainslayer must have retired, as I sure haven't seen him around much, lol.

[ifzaal002]

Thanx Bro for ur detailed answer... I know that it is not easy to test the kit for each and every type of router ...
I appriciate ur work and contributions for the DD-WRT.
@tivier bro i have also wasted my full 4 to 5 months fighting with dd-wrt but now i am moved to OPEN WRT ..
It is easy to customize according to ur needs... I will suggest u to give a check to that... THATS all what i can tell u... By the way why u are trying to modify...

[Jeremy Collake]

You might want to try again with latest version of FMK. It has gotten much better the last month. A new contributor has joined. Also, add this as an issue to the Google code project for the FMK if it still does not work..

[ifzaal002]

I will try ......... even though i have got my work done through the OpenWRT .. but i will try ..
Thanx for ur update....

[Bgs]

Any news on this? I ran into the same problem.

FMK updated from svn to the latest. (At revision 238.)

Some additional info:

I strace'd the extraction and found where the problem occurs:

[pid 22290] execve("./src/squashfs-3.0/unsquashfs-lzma", ["./src/squashfs-3.0/unsquashfs-lzma", "-dest", "working_dir/rootfs", "working_dir/image_parts

[pid 22290] write(2, "Can't find a SQUASHFS superblock on working_dir/image_parts/squashfs-3-lzma.img\n", 80) = 80


Indeed, doing az unsquashfs in the above image from commandline also gives me:

Can't find a SQUASHFS superblock on squashfs-3-lzma.img

Some additional googling gave me a solution:

Yes, extract-ng.sh is a recent addition (last couple weeks) made by Craig Heffner. It will successfully handle many more firmware images than the original script and tools. I believe that extraction/rebuilding of the DD-WRT web UI is now possible as well.

[heffnercj]

Bgs: Glad extract-ng works for you! It should work with a lot of additional Linux firmware images.

Jeremy: Yes, we can now extract, modify, and re-build the DD-WRT web UI. I actually just announced it here on the forums (http://bitsum.net/forum/index.php/topic,891.0.html).
