  1. Suddenly current off while reset set box processing ,so continuously software loading page restarting (screen displayed-loader data download in progress).long time it only show ,how to rectify it ,

    1. You can not upgrade it now as updates are pushed by OTT. Trying to update may corrupt the firmware.
      Please contact customer care or switch to new STB by surrendering current one.

  2. I have balane then only home channel is coming and not any other channels are coming error 133.4 is coming what to do??

  3. I have d2h rf2244 set top box and the remote is not working. I tried to connect with smartphone but rf remote is not checked on YouTube, it saying require bluetooth dongle to connect smartphone. Can you please suggest another option. As i am not able to operate my STB.

    1. Bluetooth adapter/dongle is the primary requirement since set top box doesn't have inbuilt Bluetooth device. The another option to try using MI Redmi or any mobile phones having infra red capability i.e. IR blaster. Many small to medium range Redmi phones have this functionality.

  4. Hi I have some problem with my dth connection some channels are playing others are not playing it showing technical error or no signal what should I do please tell me

      1. Dear sir
        I have Videocon led DDB tv3 years old
        Tv . Now it is not getting boot not get updated. Just hang.
        Tv ,android ,u tube everything is working but d2h related section is just hang.
        Due to Videocon problems not getting PCB of D2h part.i need Videocon D2h software . As display saying no staware so can not update.

    1. User's you try to connect your d2h box with mobile d2h remote app but you not stye connect this is not problem
      1. Switch off your box
      2. Setup your Bluetooth adepter in USB
      3. Switch on your box
      4. Go to your Android phone and
      download d2h remote app
      5. Open your Bluetooth connection in
      mobile now your Bluetooth adepter
      address appear on your mobile tap
      This in few seconds your d2h box is
      connected to your mobile now start
      Your d2h app in mobile and use as a
      Virtual remote.


  5. can we download this software and update manually through USB...As my product is Inbuilt DTH TV (no separate DTH Box) & is in hanged state.

    1. I am not sure about that. But I think the upgrade should be provided with the TV software update it self. Also, if inbuilt DTH is in hanged state then better try resetting TV settings if not tried already. The best way to find out a solution is to contact the TV company's customer care irrespective of TV is under warranty or not.

  6. Thank you it worked.
    What is pin for "Restrictions"?

    Tried all regular pin as 1234, 9999, 4321, 0000 etc. But none worked.

    Technical pin is working for "sat entry points" is working as 4th6th8th10th digits of box serial no.
