H520E RTK update problem

[polskipilot]

1.I am trying to update the H520E RTK drone software I am following the update procedure. Then I get the message "Installation blocked - For security reasons the tablet is set to block installation from unknown sources".
I deselected unknown sources in the settings, but after a reboot the DATA PILOT and only its update is blocked from the start (without a reboot also).
At the same time it is not possible to control the camera because despite the reconnection (of the drone with the camera) the control still does not work (there is an image and the drone flies normally).
What should be done in this case? (I attach a photo).
2. the current position is not displayed on the map.

Your screenshot shows the controller battery at 48%. The controller should be at a minimum of 50% to initiate an update. I don't think the update is actually blocked until 40%, but it would not be a problem to charge the controller anyway.
The file in this link is Version 2.2.53. You can copy it to your ST16E and try to install it manually.
datapilot.apk

Were you having the camera control problems before the attempted update?

Update.
I downloaded to version 2.1.22 and tried to use the normal OTA update to go the Version 2.1.53. The OTA update from the controller versions page failed, stating the new file signature conflicted with the existing file signature. It appears the file in the OTA update has an incorrect signature and may be corrupt in some manner.
@Enrico Jorysch may have more information about the file.

Again, the file linked above is the latest, and it installed on this ST16E with no problems by:
1.) Uninstalling the existing APP.
2.) Transferring the APK to the controller.
3.) Running the installation manually.
However, the manual update will also fail if you try to install the new APP with the previous APP still in place. I think I would not try to manually install until Enrico or someone else has a chance to comment on the security of Version 2.1.53

Thank you for the information, I will wait for Enrico and his instructions.
And the problem with the map and the location, how to solve it?

 

[polskipilot]

Yes the camera control problem occurred before

And the problem with the map and the location, how to solve it?

Please describe the map and location problem or provide a link to where the problem was described before.

Generally when I am outside in the bottom left corner there should be a map with my location and there is just a white rectangle and a triangle on a white field and that's it and there should be a location.

You may have lost your stored map during a factory reset or a firmware upgrade. The map should have restored itself automatically when you connected the ST16S to the internet via WiFi. Since it did not, try this to restore the map:
1.) Go to Settings/WiFi
2.) Select ALL WiFi sources (home, office WiFi) and "Forget" any that are connected. You may also need to "Forget" any that have previously been connected.
3.) When all have been forgotten, choose one available WiFi to which you know the password and reconnect to it.
The map should appear within a few seconds.
