How to extract system.img

Requirements:
Quote:

* Windows XP or newer
* Ext4 Unpacker
* Ext2Explore
* System.img of your choice



Step 1:
The first thing you need to do is to launch the Ext4 Unpacker software and then you need to select the open button.






Step 2:
Select the system.img you want to extract.






Step 3:
Press the "Save as EXT4" button.






Step 4:
Select where you want to save the .ext4 file and enter a name with the extension .ext4, then press Save.






Step 5:
Wait while the ext4 image is being unpacked.






Step 6:
Launch the ext2explore software as a Administrator (Do that or it wont work!) and then select File then Open Image.






Step 7:
Select the file you saved earlier with Ext4 Unpacked software and then select "Open".






Step 8:
Now highlight the file you just have imported in EXT2Explore and then press the "Save" button.






Step 9:
Select where you want the unpacked system files to be placed.






After that is done just go to the folder and voila! The android system files should be in the folder.

Trying 3 times to unpack an system.img file from my HTC One SU T528W but the ICS/JB/Ext4 unpacker everytime gives me same error: "List index out of bounds (327680)".
And it stuck there.

Why?
What's happened?

Thanks for your answer.

Thanks. This thread helped me. I overwrote my systemui and needed it back. Is able to use this method to extract it from the Google factory image for my galaxy nexus. You do it once and it's pretty straight forward.

Make a update.zip, easiest way to do it.

I need to pack files back into a system.img file and it can't be an update.zip file. I need it for emulation purposes.
