Hi,
So I've followed the instructions to downgrade my S26 Ultra from the beta program; opted out via Members app, then using Windows Smart Switch PC attempted to downgrade. However it seems I'm getting stuck on 100% "Checking the Downloaded update files..." popout. This was after being asked to ensure the phone was not in AutoBlock mode.
Does anyone know roughly how long this stage takes, as I'm worried it's crashed.
Also feedback for the developer of Smart Switch - please give more details as to what the program is doing! A 22gb download for One UI 8 and no speed or ETA is quite frustrating! Just let the end user know what is happening!
Thanks in advance.

I hadn't realised this to be honest.
The issue I've had is my AOD hasn't worked once since installing the beta. I had hoped to downgrade but kept putting it off.
I now just get failure / bugs when trying to downgrade so guess I'm stuck for now.

If the downgrade process is still getting stuck at “Checking the Downloaded update files…”, please report this through the Samsung Members app so the issue can be investigated. I’ll also pass your feedback about the lack of progress information in Smart Switch on to the relevant team for further analysis.
