Root Recovery works only with adb

[Sekhmet]

Hello.
I install amon-ra recovery on my LG P350.
If I write "reboot recovery" via adb, Recovery works fine.
But if I write that via terminal emulator or with {power off, call + vol down} - open hard reset.



Somebody know what is wrong?

Android Froyo, V10f, root via Gingerbreak.

Sorry for my English.
