我已经从下载了一个 SD 图像加载器恩智浦网站。下载的项目的名称是O8.1.0_1.4.0_ANDROID_TOOL_7ULP_GA（顺便说一下，这不是一个 Android 问题）。
我的 SD 卡上加载的图像位于压缩文件中，名称为
recovery-imx7ulp.img
我想在将此文件加载到 SD 之前修改此图像。我应该使用什么软件来打开此图像？我无法识别文件系统。
该.img文件可能是原始图像。但是，我仍然不知道如何安装它。
这是我的尝试。

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
