我扎根了我的Android手机并获得shell thr adb。我想在Android中挂载一个ROM图像。但我总是失败：

mount -o循环/sdcard/myimage.img / mnt
挂载：无法设置循环设备：没有这样的文件或目录

I have rooted my android phone and get a shell thr adb. I wanna mount a ROM image in android. But I always fail:

mount -o loop /sdcard/myimage.img /mnt
mount: can't setup loop device: No such file or directory

最佳答案

尝试： mount -o loop /sdcard/myimage.img myimage 。 "myimage" 是您可以在后面查看内容的地方。

Try: mount -o loop /sdcard/myimage.img myimage. "myimage" is where you can view the contents afterward.

您需要编译一个能够安装循环设备的自定义内核，或者找到已内置该功能的该设备的自定义内核。

经过一点挖掘，我找到了本指南在我的手机支持论坛上。这有点日期，但信息仍然是相关的。它显示了如何启动Debian .img文件。不幸的是，它并没有详细详述循环支持所需的内容，只是需要循环支持。但它绝对可能，因为我亲自在手机上运行了很少的时间。

You would need to compile a custom kernel that is capable of mounting loop devices, or find a custom kernel for that device that already has that feature built-in.

After a bit of digging, I found this guide on my phone's support forum. It's a bit dated, but the information is still relevant. It shows how to boot a Debian .img file. Unfortunately, it doesn't really detail EXACTLY what's needed for loop support, just that loop support is needed. But it is definitely possible, as I've personally run this on my phone for a short amount of time.

我能在我的银河系上用股票rom使用mount Matthew Read 2011-01-25 21:40:17Z, License: CC BY-SA 2.5

安装，肯定。安装在股票rom上不是问题。但安装循环设备？我所看到的大多数库存内核没有默认启用循环设备安装。 c0mp13371331337 2011-01-25 23:00:42Z, License: CC BY-SA 2.5

@ C0MP13371331337在我的Android 4.2.1设备中发现的问题是使用股票ROM的山上二进制文件。它根本无法安装循环设备，而是忙音箱的挂载。 Firelord 2015-12-06 10:29:54Z, License: CC BY-SA 3.0

I was able to use mount on my Galaxy S with a stock ROM Matthew Read 2011-01-25 21:40:17Z, License: CC BY-SA 2.5

Mounting, sure. Mounting on a stock ROM is not a problem. But mounting a loop device? Most of the stock kernels I've seen don't have loop device mounting enabled by default c0mp13371331337 2011-01-25 23:00:42Z, License: CC BY-SA 2.5

@c0mp13371331337 the problem I found in my Android 4.2.1 device was with the mount binary that came with stock ROM. It was simply not capable of mounting a loop device but busybox's mount does Firelord 2015-12-06 10:29:54Z, License: CC BY-SA 3.0
