Trendnet TEW-671BR firmware support
« on: January 03, 2013, 10:30:35 AM »
Is it possible to add support for TEW-671BR firmware in Firmware Modification Kit?
I've tried to extract firmware, but it returned me some errors saying that firmware image format isn't compatibile
Here are these errors:

Extracting TEW-671BR-APPS-V1-2-6-5.dlf to 1 ...
Error: filesystem not extracted properly.
 firmware image format not compatible?

Extracting TEW-671BR-KNL-V1-2-6-6.dlf to 2 ...
Error: filesystem not extracted properly.
 firmware image format not compatible?

There are some sources on http://www.trendnet.com/downloads/list_subcategory.asp?SUBTYPE_ID=1344 for this device

Probably nobody has added support for that firmware image type. Whether anyone will, who knows. Submit as a ticket on the Google Code project site.

Thanks for reply anyway.
I've created new issue:

What is the difference between Accepted and Started in status ??

Accepted means someone intends to start it. Started means they actually have.

  The TEW-671BR firmware cannot be extracted by Firmware Mod Kit because of 2 reasons.

1) Most importantly because of firmware files are encoded by unknown encoding algorithm
2) Firmware comes in 2 files, one with apps and another with kernel.

However what is most important and leading for my success in case of firmware extraction possibility is that the encoding
algorithm is simple enought that I was able figure out the most important part of how it works through reverse engineering
on about 250 diffrent ruter settings backup files which are also encoded same way as firmware image files. I said "the most
important part" because I don't exactly know how headers of these ancoded files are constructed(probably first 96 bytes),
but encoding is simple - original byte at given offset is mapped to some other byte. Byte at offset X ancodes axactly the
same as byte at offset Y if X % 8 == Y % 8, where X and Y are offsets in encoded files. Based on that fact I've written
little app for files decoding. Source of this decoder is at end of this post. I'm not sure if it'll compile with linux -
I'm not advanced programmer, just write only some little apps for windows only. However if it doesn't compile with linux
then it's very easy to modify code that it will. Using this app I converted TEW-671BR-APPS-V1-2-6-5.dlf file to app.bin file
and TEW-671BR-KNL-V1-2-6-6.dlf to knl.bin file.
Below is what I was able to do.

Please report all FMK issues to the Google Code site. That is what the bug tracker / issue tracker is for. Firmware Mod Kit

If you have contributions to make, please make them there. We can even give you commit access if you end up being a big (and cautious) contributor.

I have a question about FMK tools.
Does it is normal that after file extraction and packing it back without any changes to extracted content the original file and repacked file differ a little in size ?
Please look at this log:
http://rapidshare.com/files/306575985/log1.txt
Original file size is 2651422 bytes but after repacking it takes 2663678 bytes. What causes the difference ?. Is it normal ?

Yes, it is normal. The particular compression parameters used can cause small (or large) differences in the compression ratio. The FMK likely uses slightly different compression parameters than the OEM does.

    You were not exactly right about Your answer, that is I think that's true about particular compression parameters used but in some other case, not here. I know because I've tested it. The first firmware file is "squashfs-3.2-r2-hg612-lzma" file(after decoding it of course), however it can be also unsquashed(unpacked) with "squashfs-3.2-r2-lzma". When I packed back unpacked content with "squashfs-3.2-r2-lzma" then router refused to accept file(after encoding it back of course), but when I packed it back with "squashfs-3.2-r2-hg612-lzma" then it produced exactly same binary file except header, where is the timestamp. I was able to make my first modification to firmware - change language from uk to my native - well not completely but partially to test if it works ;D. It was simple thing - just changing strings in uk.txt file.
    And one other thing - FMK doesn't provide tools for unpacking and repacking U-Boot uImage files, so in fact I can't even completely unpack firmware
