Can't Clear Partition Cache

As part of troubleshooting another issue, Samsung's tech support advised that I follow instructions to Clear Partition Cache. Having followed the instructions given, found instructions online and watched videos on how to perform the activity, I could not Clear the Partition Cache. Instead my phone displays the following system message: 

 

[PDP] 

back-up : fail 

setup-wizard [ FINISH ]

 

Many webchats and calls later, including a 'repair, Samsung have not been able to confirm the problem or provide a solution.

Any thoughts on next steps welcome!

 

thanks.

Turns out that the phone needs to have a wired connection to a computer to be able to load the Recovery Menu from which the Wipe Cache Partition option exists. Once the phone is off and connected to a computer, then follow the existing instructions: hold down bixby and volume up buttons until it loads the recovery menu.

 

According to Samsung Tech Support the need to have a wired connection is a consequence of Android 11.

 

Getting to this point has required many calls and webchats, and an unnecessary repair. Sounds like the need to have a wired connection has caught Samsung on the backfoot as they said this was a 'workaround'.

While your device is powered down are you holding the power button and volume up button at the same time?

yes. I have followed the instructions provided verbally and published online. I have also watched video tutorials. No matter what I have no luck.

 

Discovered the problem before sending it to Samsung for repair, which they said was not required!

 

Could it be related to upgrade to Android V11?

I was able to clear the cache by simply plugging in USB c headphones then power off and use the procedure mentioned elsewhere to clear the cache partition.
