[Solved] evobox lite decoder update error 0xa6 then crashes anyway over and over again.

Hello, I have a problem with the evobox lite decoder, namely the decoder updates every time I turn it off and it takes more than 10 minutes, then it starts downloading and after a while the error 0xa6 is displayed, then it turns off and so on over and over again.
Interestingly, it already has the latest soft.
This is the third decoder.
Antenna 80 assembled by a professional converter from the polsat antenna.
MER at the level of 13.5 - 14 signal strength around 80 quality 75

I wanted to ask if anyone else had a similar problem because they did not help much on the hotline, thank you in advance

This is not normal behavior. What type of converter do you have set up in your antenna configuration?

The converter is set to universal

1. Disconnect the power.
2. Disconnect the cable from the antenna.
3. Connect the power of the decoder and wait for it to start up.
4. Go to the Settings / Hardware Settings menu and restore the decoder to the default settings.
5. After rebooting the decoder, the first installation screen will appear.
6. Disconnect the power and reconnect the antenna cable.
7. Reconnect power and perform First Time Installation. During the first installation, do not connect the set-top box to the network.
8. Write down how it went.

So far I have a new one that cannot be activated, I suspect that it has something wrong with the card because there is a different number on the screen than on the bottom of the decoder

If possible, connect the set-top box to the Internet, then the activation will be faster.
The customer number displayed on the message screen is for technical purposes.
The most important information for you is in the menu Settings / Diagnostics / Conditional access.
The card inserted into the decoder is not currently being used, so do not take it out and do not be influenced by its data.
To activate the decoder, turn it on and leave it on channel 1 or 23.

but the converter was nuts
