adb pull /data fails I have rooted my device HTC Evo Design 4G and I try to adb pull /data data and it says "0 files pull 0 file skipped"

I was able to pull /System/build.prop. How can I pull root folder. 

Thank you

Files and directories below /data/data are protected from the "average user", so you cannot simply "pull" them unless the ADB daemon is running in root mode. Other than the file you were referring to (/system/buildprop is at least readable by all apps), folders below /data/data are "invisible" (except for root), so they cannot even be read.

To be able to use adb pull on them, you need to make your ADB daemon run in root mode first. Depending on the device, a simple adb root command might do that – but most devices will refuse to do. In those cases, you can use chainfire's adbd insecure: Install this app on your device, start it there, and manually switch to "insecure" mode. Now the pull should succeed.

Remark: It's called "insecure" because running adbd as root gives everybody with a computer and an USB cable access to everything on your device. Just in case you wonder.
