55.1.A.9.52 Xperia 5 security patch problem

ijk_krakow_poczta.fm — Sat, 25 Jul 2020 21:26:06 GMT

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
Tap on the cogwheel and you're in settings
Scroll to System -> Backup and switch on <Backup to Google drive> and <Google photos> -> Backup & sync. (Do not forget to read the Back up & sync help by tapping the ? in the top right corner of the screen)
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.

Connect to a computer and do a software repair with Xperia Companion.

Instructions can be found here.

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...?
