S21 Ultra is not updating

[masterandkisan]

Hi, my s21ultra is not showing android 13 one ui 5 update instead it shows system has been modified in an unauthorised way. Smart switch shows device software is upto date: VIF, And in Settings > About Phone > Status > Phone Status is custom, maybe due to I updated it by smart switch. Now what should I do? I'm from Islamabad.
