Hey everyone - Long story short: I want to extract the firmware from my generic chinese headunit. I've done something similar in the past (Well someone smarter than me did it LOL). I've already dumped the firmware from the headunit, and been examining the firmware by the ways i know of.
- I've ran DMDE on it (No results)
- Ran binwalk on it (Gave a lot of interesting results)
- Searched for filesystems (There is definitly one or more of them)
- Looked for clues as to what kind of partitions there might be (No results)
What i know so far is: The operating system appears to be 'eCos'
I'm not entirely sure, because the processor's identification has been washed away, but my guess is, that it is some type of ARM processor.
I've found boot sections, uImage headers, and lots of LZMA compressed data.
Ultimately the end goal is to replace the boot logo (I've already extracted some photos from the firmware, that i've never seen when using the unit itself, but i haven't found the boot logo so far), but i'd love to extract the firmware totally and have fun browsing around and exploring
Hopefully someone in here, can help me on my way.
Thanks!
(I've attached the firmware below.)
: I have to attach the firmware this way, because the file is too large otherwise :
