Applying the Unlocker

If you select a feature which requires the EZ-GUI Unlocker, you will be asked if you want to unlock. If you say yes, you’ll go through the usual Google Play Store in-app purchase process – confirming the price and so on – and then taken to the Play Store to install the EZ-GUI Unlocker.

Once the Unlocker app is installed, you can’t open it – you don’t need to. Just return to MultiWii EZ-GUI and select a locked feature again. You’ll get the “Do you want to unlock” question once more – but when you say yes this time, you’ll be taken to the unlock screen. Select Unlock there, and you’re done.

Note: Applying the Unlocker unlocks all locked features, not just the one you select.

      Could you describe it with more details? Because if you buy something from google play store it should stay yours as long as you use the same google account as in the time of making purchase. There is even no possibility to pay again. If the app ask you to install unlocker again and you go to the google play store app and it asks you to pay again something is wrong. Either you don’t use the same google account as before or (I’ve heard it many times) the problem is on google side. In this situation please contact google support and they usually solve the issue.

      This is what I can see on my side (I’ve removed order IDs):
      GPA.xxxxxxxxxx 15/05/2017 14:37 EZ-GUI Ground Station Unlocker Charged $4.49
      GPA.xxxxxxxxxx 15/05/2017 14:36 EZ-GUI Ground Station Unlocker Refunded $0.00

      It looks strange that the app was refunded before it was purchased. Probably you will have to contact google support to clarify that, as I don’t have any control over it. This above is all info that I can get from Google.

      Lets discuss it here so the other people with the same problem can read.

      I want to solve this issue also as I got few complains like this but we never have found what was the real problem.


  2. Can you explain the in-flight PID tuning function?

    • In-flight PID tuning is the same as the normal PID settings but it allows you to change one value at a time. The values are not save permanently in the EEPROM because writing to EEPROM takes some time and produces glitches during the flight (I’m talking here about MultiWii, not sure how it works in cleanflight). So after you finish playing with In-flight PID tuning you have to land and save the values using red buttons in top right corner. I hope this is clear enough.

  3. I can’t get Google Play on my Fire HD. Can I purchase on my android phone and side load to my tablet or does it need google services to operate?

    Si tuviera que cambiar de móvil, ¿como puedo recuperar el unlocker?

    • You can do it as long as you use the same google account on both phones.
      If you bought the unlocker you can download it and install without paying on other devices as but the google account used to do it has to be the same along all devices.
