Interesting. It might be possible to modify the firmware image before
re-flashing the device, if it is a bootable disk image. For example, the
IPcop router software is available as a bootable image that can be
transferred to a flash card and booted on a diskless system.
What does "file <router flash image file>" show?
Well, this router (a comtrend CT536+) gets its image depending on the ISP
supplying it, and my ISP hasn't published any image, as far as I know. The
other ISP has, but it is slightly different so I won't flash it with that
image. And I can not extract the current contents, there is no command for
it.
I can run 'file' on the other isp flash image, but it says it is just
data:

CT-536B-A101-302JAZ-C01_R05.bin
CT-536B-A101-302JAZ-C01_R05.bin: data
I do have the sources, but also for the other provider, and no "making"
documentation, so I will not try - you know the saying, if it works, don't
touch it ;-)
