参数2文件夹路径

erofs 打包

tool\mkfs.erofs -T 1230768000 \
--mount-point /system \
--fs-config-file system_fs_config \
--file-contexts system_file_contexts \
-zlz4 system.img system/
在 windows 中,请用一行
tool\mkfs.erofs.exe -T 1230768000 --mount-point /system --fs-config-file system_fs_config --file-contexts system_file_contexts -zlz4 system.img system/
参数说明
help帮助

mount-point挂载点
fs-config-filesystem_fs_config 文件路径
file-contextssystem_file_contexts 文件路径
zlz4压缩方式(有 lz4,lz4hc 等)
末2镜像路径
末1文件夹路径

去除 avb2.0 校验

使用命令
fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta_system_a vbmeta_system.img

镜像文件
https://blog.xzr.moe/archives/226/
https://github.com/libxzr/vbmeta-disable-verification

挂在镜像

mkdir /temppath
mount imgfile.img /temppath

注意

  1. vbmeta.img 和 vbmeta_system.img 需要关闭 avb2.0 校验
  2. data 分区加密在 vendor.img 里,去除之后 data 分区就不会根据密钥加密了
  3. erofs 解包后,添加或删除文件时都需要修改 system_fs_config 和 system_file_contexts ,可以用记事本打开它
