Phone Locked

Hello everyone,

I have a Galaxy A70 on latest May 2021 One UI 3.1 update, phone was working fine till this morning, when I tried to manually update some system apps.

I downloaded Device Services latest release from apkmirror, once I installed it, the device showed a "Phone Locked" screen, with IMEI on the next line, followed by:

"This phone can't be used without authorisation"

WiFi was connected for a few hours, I can receive phone calls, even Whatsapp calls, Google Assistant & Bixby are working fine, everything is cool except the fact that I can't bypass this lock screen.

I can use ADB, my bootloader is still locked, my phone has never been modified. I don't want to lose internal data by doing a factory reset.

Any help would be marvelous. Thanks.
