Got the notification that G955WVLU8CTF3 /G955WOYA8CTF3 was available to download (Security patch July 1 2020). Normally it works without a hitch, but after this update it says i have an invalid sim card in the notification tray. I cannot make any calls, text, or use mobile internet.
My phone is unlocked and had been working flawlessly prior to this update. Any ideas on how to fix this? Thanks.

This latest update bricks modem part of firmware on some devices, ways to solve that is to wait for official fix with no ETA or flash modem part from the latest XAA firmware for SM-G955U1 ( US unlocked version ) <HIDDEN> ive uploaded latest odin and modem file. Turn phone off and hold bixby + volume down + power till it boots into download mode, vol up to confirm, connect phone to laptop, start odin, click on CP , pick modem file and press start. phone will auto reboot and becomes fully functional. Not sure it will get all the ongoing updates automatically after that modem swap but it turns brick back to life.
