"adb sideload" worked but "adb shell" not.

[JasonLong]

Hello.
I have a Samsung "Galaxy Tab 10.1" and want connect to it via "adb" but i can't. I booted my device into bootloader and can send file via "adb" but...
$ adb sideload /home/jason/test.pdf
sending: '/home/jason/test.pdf' 100%
$ adb devices
List of devices attached

What is your idea?

adb on your pc talks to an adb daemon (like a server) on the phone.

It can only do what the daemon is set up for.

When you enable USB debugging on a running phone, all you've done is start the adb daemon.

When you're running at a lower boot level, like a custom recovery, you may get limited adb services - devices and sideload. That's it. It's running a separate daemon.

You can't change it. You're not going to get more out of it. It is what it is.
