    I've tested now for a few days these Cloud Ibox 4 with the VuJ chip modification on two original VuDuo image files, with the latest version Openpli and OpenaAtv without any problems.

    So, as far as I see it is the VuJ security chip perfectly working with this box.
    The security chip can be found on the print side, the UU1, you could remove it, or disable the chip from the Sda/Scl cpu circuit by changing the direction of the two resistors, but that is more difficult to preform and also a bit of risky because you could break a solder track on the motherboard..
    Anyways, pictures say more, so I have made (of course) a information drawing of how it can be done.

    Good Luck...

    I've bought some defective Cloud Ibox 4 boxes to play with and since I also modified one to the VuJ chip I place a repair story from one box here.

    I started with one box, which is death, only a red led but the terminal output shows the famous Epc error which could be related to the security chip or a wrong cfe loader.
    In any case, because I already had decide to modify it to the VuJ chip, I started first to modify it, but this time without removing the security chip UU1.

    I've disabled the Scl/Sda output from the chip by disconnecting the two 33 ohm resistors R700/R710 from the UU1 chip, just as the instructions drawing shows in the beginning of this topic and added two thin wires to the Scl/Sda resistors.
    Not a easy thing to preform, but with a little patience and steady hand it can be done.

    Then I've placed the motherboard back in the case and brought the two wires to the parts side like this.

    Then it were time to mount the VuJ adapter board and to see if the issue solves.
    Just as the instructions drawing shows, I had soldered the two wires, used the screw for the ground, and taken the 3.3vdc from the L001 inductor which is the output side.

    Picture shows the L001 wiring,

    Okay, so far it seems fine, and now the test....
    Well, it didn't helped, it still showed the Epc error as if the chip doesn't work.
    Later, when I was at home I saw probably why it failed, despite the fact I had designed a pretty nice VuJ adapter board, at least in my opinion, and had it wired it the good way, I have made a little mistake with the Sda/Scl text on the board, because it needs to be swapped. :oops:

    So, there is still some hope that it will be fixed, this story will continue. :rolleyes:

    ----------- Update,

    Indeed, after connecting the two wires Scl/Sda the correct way this receiver just works flawless.
    And so again a duo box cloud-ibox 4 rescued from the death, and is ready to run the newest software. ;)
