EROFS stands for Enhanced Read-Only File System. It is a read-only filesystem introduced in Linux 4.19. It supports compression and deduplication, and is optimized for read performance.
This guide will explain how to unpack super.img to get system, vendor, product and odm etc. We'll also show how to extract these if they're in EROFS format e.g system
Requirements
- Download these binaries @ https://mega.nz/file/owhn1BTY#YBhswbqJN9...na0rVPehEs
- Download erofsUnpackRust @ https://github.com/thka2016/erofsUnpack/releases or https://mega.nz/folder/Joo11QBA#W6EKGnJTuupJewH7inAyHw . I'm using a 64-bit PC so the above zip includes erofsUnpackRust_x64linux. Download one for your PC type and extract
- super.img for your device
- A Linux-based PC. Windows users can use Vmware Workstation Player
How to unpack images in EROFS format
- Extract the binaries and super.img into the same folder. Your folder should contain lpunpack, erofsUnpackRust, simg2img and super.img
- Run this command to unsparse the super.img
Code:./simg2img super.img super.raw
- Unpack super.raw using the command below
Code:./lpunpack super.raw
- Extract system (mine is system_a.img) using the command below
Code:./erofsUnpackRust_x64linux system_a.img
