I get the hash prompt, but I can't list the files in /data (or do anything that requires superuser permissions). I don't have Superuser.apk installed, I don't want to install it because of that grant/deny access dialogue that pops up if you wipe the device. What does Superuser.apk do that I can't do when I unpack the *.img files?
输入 su 首先。
＆gt;苏
＆gt; ls / data
确保您的设备已植根。
Enter su first.
> su
> ls /data
Make sure your device is rooted.
对于某些操作，adb也必须作为root运行。
您可以通过运行 adb root ，轻松地重新启动具有root权限的adb守护程序。。
然后，您可以再次输入 adb shell ，用 su 并在您想要的地方进行导航。
当我完全相同的问题时为我工作。

其他人的补充：
某些超级用户应用程序在配置中有一个选项，以允许根权访问APPS，ADB或两者。默认值不一定允许adb根访问。
For some operations, adb must be running as root as well.
You can easily restart the adb daemon with root permission by running adb root.
Then you can enter adb shell again, switch to root with su and navigate wherever you'd like.
Worked for me when I had exactly the same problem.

Small addition for others:
Certain superuser apps have an option in configuration to allow root access to either apps, adb or both. The default is not necessarily to allow adb root access.
