Sideload App by SDB - Problem with uninstall wgt

Hi to all,

I have the smartwatch Samsung Gear S, I followed the steps to activate the device without pairing with a smartphone then I followed the guide published on this forum to rooting the device.
I succesfully used sdb program to install apps but when I tried to uninstalling I have a problem:

If I try to uninstall wgt file that has an appid in the config.xml like that:
<tizen:application id="niWLAQQEtB.XenozuPlayer" package="niWLAQQEtB" required_version="2.2"/>

sdb uninstall niWLAQQEtB

It's all right,

But If I try to uninstall wgt file that has an appid in the config.xml like that:
<tizen:application id="com.samsung.w-voicerecorder" package="com.samsung.w-voicerecorder" required_version="2.2"/>
sdb uninstall com.samsung.w-voicerecorder

An error occurs like taht: error: package type unknown: [rpm]

Anyone can help me? Or Anyone know how to do to uninstall by sdb command?

Thanks to all.

Alex
