55.1.A.9.52 Xperia 5 security patch problem

[ijk_krakow_poczta.fm]

After 55.1.A.9.52 security patch install on Xperia 5, all SIM card mobile services stopped working. SIM Card is visible but phone radio is not working. Checked with other SIM Cards and other mobile providers, same issue. SIM Cards on other phone work. Factory reset does not help. Anyone encountered similar problem?

Something must have gone wrong in the update process.

Please charge your device to > 80%, read instructions for backup 

Let Google backup your device

• Swipe down from the top of the screen with one finger twice or with 2 fingers once

• Read the Google backup help page on the internet.

Make a separate backup for WhatsApp, Signal, Telegram or whatever you're using from inside the app itself.

Hi, Unfortunatelly software repair using Xperia Companion did not help. There is still radio module not working. SIM Card is visible by phone but radio module inactive. In this case I think only authorise service can help...?
