DFU Upload failed is not displayed on Xperia1Ⅱ(Android11).

[YoungSooBae1224]

I tested DFU on Xperia1Ⅱ(Android11).
I accidentally clicked All on the "Select scope" screen. (Application only test)
The Xperia1Ⅱ started to transmit strangely.
The problem is that the nRF52805 freezes after doing these uploads.
Is there any way to fix this situation?

I accidentally clicked All on the "Select scope" screen. (Application only test)

The screenshot says the Scope is "All".

The Xperia1Ⅱ started to transmit strangely.

What does it mean strangely?

The problem is that the nRF52805 freezes after doing these uploads.

It depends on your firmware. If the ZIP file contains SD+BL and App, the usual upload (All) would transmit SD+BL in first connection, then restart and upload App in the following one. The App's init file should be configured to require specific SD version, given in --sd-id parameter in nrf util. If you created a package without giving this parameter, or you provided the same as in --sd-req, the App upload would be successful, as the verification would pass, but your new App would not be compatible with the old SD. So, it all depends on your firmware and how you created the ZIP file, with which parameters.

Is there any way to fix this situation?

I don't know what is the issue, so can't help here.
