    Main point is:

    self-signed installation package or not?

    which UID (unprotected or protected)?

    which capabilities (some require protected UIDs, which prevents use of self-signing)?

    also, check the installation settings on the phone (cert check required or not).

    Well,

    I am using protected range UIDs like: 0x20048E3F, 0x20048E41 and capabilities like: TARGET.CAPABILITY = All -TCB -AllFiles -DRM.

    So for the above any kind of signing is required? I checked in Wiki... the capabilities related to device manufacturer, so may be developer certificate required..

    What your views on this?

    Thanks...
