[DEV][Tools] simg2img for Windows

[8ohmh]

Hello, although I'm working in Linux (VM too) I rewrote the SIMG2IMG so far for Windows (PE32, x86)

Usage: simg2img.exe -i <chunked Image file name> -o <outputname>

Optional: -d for debugging messages, listing all chunks of the image (.ext4.img) files to stdout (in case there are partial image files )

MD5: e5fc02b2f27756c1de270d31e29447e6 *simg2img.zip

Error calling ftruncate() to set the image size

simg2img.exe -i system.img -o system.ext4
packed img filename: system.img
output img filename: system.ext4
Error calling ftruncate() to set the image size

Note: system.img is 1.9G.

simg2img.exe -i system.img -o system.ext4

output img filename: system.ext4

I got the same problem when I ran this on system.img.ext4 from the Samsung Galaxy S5 Lollipop firmware. However, the output file still looked like it was the right size, and EXT2Read opened and extracted it without a problem.

Same problem here:
packed img filename: system.img
output img filename: system.img2
Error calling ftruncate() to set the image size

Output file was 2.8GB, input file 2.4GB wich looked OK, so I tried opening the output file with ext4_unpacker_exe wich failed, then I tried opening it with ext2explore-2.2.71 and it was able to open it !!!!

Thanks

G:\vbox_share\simg2img>simg2img.exe -i userdata.img -o new-userdata.img
packed img filename: userdata.img
output img filename: new-userdata.img
Wrote "new-userdata.img"

The userdata.img only 21.4MB , but the new-userdata.img is 1.19 GB . Is right ?

I couldn't get this version to work, but I did find another version that did. I then created this thread with complete instructions: [GUIDE]How to extract /system from Samsung S7 OTA/FW in Windows without a Phone Hope it helps. Thanks!
