T113’s system partition is usually ext4 with sparse format.

Convert sparse to raw:

simg2img system.img system_raw.img

Mount or extract the raw image:

mkdir system_mount
sudo mount -t ext4 -o loop system_raw.img system_mount

Or use extract.erofs if it’s EROFS (rare for T113).

Repack contents after modifications (e.g., add/remove APKs, edit build.prop, change fonts, etc.):

sudo make_ext4fs -s -l 1300M -L system new_system.img system_mount/

-s = sparse, -l = partition size (check original size via ls -lh system.img), -L = volume label. | Risk Level | Risk Description | Mitigation
