Acquiring Satelilites after update to 25.24

Hi,
I have a problem after the last update. The device cannot connect to any satellite. The indicator is at the smallest line. I've already tried resetting all settings but it doesn't help. I only use original Garmin maps, these are enough for me. The device connects to the speed sensor, although it calculates the average speed strangely because I covered the entire route at about 16 km/h and the average was 10 km/h. Throughout the entire route, I received a message that I was determining satellite positions. After the last reset, I put the device out on the balcony for 3 hours and nothing happened except the battery ran out quickly, but it was cold outside. The current software version is 25.24, the question is whether it is a software issue or the device is broken. Does anyone have a file with older firmware? Unless you have other ideas.
