How to extract vendor.img and img files held in Samsung firmware file

A few weeks ago, I was trying to install a GSI on my Galaxy A20e and wondered how I could obtain the vendor.img of my device. It seemed very complicated and I could hardly find how to do it. So I’m gonna explain it in this article.

Step 1: Download the firmware for your phone (We will extract the vendor.img from this firmware) To download the firmware, I recommend you samfw.com, wich is free and accountless while allowing fast downloads.

Step 2: uncompress the firmware file (if you do not have installed a tool that can do this, I recommend Ark, made by KDE, that does the job very well). You are not forced to uncompress everything. I made this little table with files and their contents:

File	AP	BL	CP	CSC	HOME
Images contained	dt dtbo recovery system userdata vbmeta vendor	cm param sboot vbmeta	modem modem_debug	cache omr product	cahe product

Step 3: uncompress the specific file you want

Step 4: You obtain a .img.lz4 file. To get the .img file, just open the .img.lz4 with your archive tool and uncompress it. License
