    I have a Pandigital Planet running 2.3.4 that's been rooted

    So I wanted to create a .zip file which I use to update during the recovey process to batch add apks ( the boot loader menu is Android system recovery <3e> )

    The format seems simple enough:
    there are two directories META-INF & system and it seems simple to edit an updater-script (tons of examples out there) and add the right stuff to the systems apps directory

    where I'm struggling is what appears the signing process
    - I've tried zipsigner1.1 autosign.jar, signapk all which sign the zip file from my windows 7 PC and even tried ZipSigner 2_2.3 which signs right on the tablet (they all seem to use test keys)

    - everytime when applying the update during the boot I get "E:signature verification failed&#8221;

    I know I can apply updates which others have created (that how I go the tablet rooted)

    how does one going about creating a proper .zip file that can be used ?

    thanks in advance
