why am i not able to update application via ota DFU in MCP

[deepu]

hello,

i am unable to update application or softdevice or bootloader via master control panel 3.9.0 while doing so, it shows error:"FAILED TO OPEN TRANPORT BACKEND".

The thing is i have successfully updated the same via MCP couple of times may be after trying 100 times.

But most of the time this error occurs

please help me

thank you

I had two issues. So far one has been solved. Further details are located in the linked questions. Thanks!

1. Failed to follow instructions properly and burn the bootloader (solved).
2. nrfjprog does not accept multiple arguments (unsolved so far).
