Hi,

It's unfortunately not possible to determine the root cause of this issue based on the log from the phone. You will need to use the debugger, and see if you get any asserts in the bootloader code.

You might also want to check if packet receipt notification is enabled in nRF Connect app (Open the menu -> Settings -> DFU options).

I am using softdevice 8.

Yes, I can see the bootloader in memory

The devices are not bonded.

Hi,

What SDK version are you using ?

Are you sure that the bootloader is flashed to the nRF51822 ?

Is the phone bonded to the device ? If yes, could you try to delete the bond on the phone and try again.
