Hi Juan,
There is not a straight forward way of downgrading unfortunately.

You can have a look here: How to downgrade nRF Connect plugins?

There are possibilities to downgrade but we will have to request that with R&D and they will need to create a package for us.

But I would say that the programmer should work exactly the same when you flash a hex file. I would suggest to use the command line nrfjprog.exe to program.

It's the command line backend tool that nRF Connect Programmer uses to do programming.

Hi Juan,

Could you please let me know which firmware did you test with ?
Have you tried with very simple sample for example such as blinky ?

What I can see from the log is that it has MCUBoot, and seems like there is an issue with it. Please try also to test with simple application that use Mcuboot, for example the SMP_SVR sample.
