Hi, try resetting system cache and repair apps in the recovery menu. If that doesn't work you need to try and backup your data and factory reset the phone.

If you've reset the device there's no point clearing cache. Is the phone under warranty?

Make sure your device is fully charged and connected to Wi-Fi. Swipe down from the Notification bar and select Settings. Scroll to and select Software update, then Check for updates. Follow the on-screen prompts to download and install the update.

 

Regards,

Will

Did you get a fix for your problem. I am having the same problem with my s21 Ultra when trying to update #29. The failure ode is 402.  I went to a Verizon storefront and they could not fix the problem.
