Which of them? there are different images packed in different ways, system is yaffs2 image and boot.img is packed with mkbootimg tool from android source

[Guest vache]

You'll need unyaffs.exe, but you only extract data.img & system.img. Fot boot.img you can find a tool in this tuto (unpack-bootimg.pl). It will extract ramdisk & kernel from it.

I am reading those pages and downloading the "tools".

Any hint how should I deal with those "tools" with .pl extension?

Should I run it from cmd? or what?

I am definitely a dummy but I am trying to learn as I have some technical interest in Android......

Thanks.

[i am not good at programming but I have knowledge in Borland C when I was in college many years ago.....]

im assuming pl = pearl? lol

[Guest navygino]

Success to unpack yaffs Image, relatively easy......(Read some Wiki to learn what is it.....)

Reading and learning how to extract boot.img...Still don't understand but hopefully not too difficult.

Next step to learn to repack and compile stuffs.......... :(

I had packed everything need for the unyaffs here as a tiny tool for my own use.

• unyaffs.exe
  
• cygwin1.dll
  
• cygz.dll
  
• Unpack_system.img.cmd (Put the system.img in the same folder and run with this simple cmd...)

I wanted to do the same without starting up VMware and just extract some files from a system.img/data.img under Windows, so I modified the unyaffs source and made it Windows compatible! (more or less, symlinks & hardlinks are not implemented)

Source & binary: Download (same as Attachment)

There are two binaries inside: one compiled with VC 9.0 and one with MinGW. If u don't have the VC 2008 Redistributable installed, maybe the MinGW version works. Just drag&drop the ".img"-file onto the "wunyaffs.exe" and wait a few seconds - the files will get extracted directly into the directory where the ".img" resides in.

Commandline: wunyaffs IMAGE_FILE.IMG

Maybe someone finds it useful too, so I thought I'd share <_<

Thanks for sharing :mellow: This is really useful, because every start of the virtual machine eats my pc memory and I hardly work :(

Sorry for necro-posting so blatantly, but this person has saved me from a world of trouble. It's only fitting to thank him/her.

THX nv0 & navygino. It helps a lot to unpack my "yaffs2-1.img" file of "Trekstor MovieStation Antarius Plus". But after editing, (enabling telnet) how to repack?!
