Please create a new case, with more information, sniffer trace and debug log on the bootloader.

Hello all, I have the same problem to update major softdevice version. I want to update S132 v3.0 -> S132 v5.0, I think the location of the bootloader is the same. Now I meet the situation is I can update the SD+AP+BL with the nRFconnect APP and the APP doesn't show any error and update to 100%. But after that, I can't scan any device anymore. Also I try to update only SD+BL. The result is the same. How can I do next step? Thanks.

Hmm,I'm not sure that's correct. The limitation if any is with the start address of the bootloader. It's not easy to modify that.

Thanks, that's good to know. I used it with SDK12 a few months ago and remember that limitation was still documented.

Hi Stas,

The reason I mentioned in the blog that you can update the softdevice and application is that, there will be still 2 phases, first updating the softdevice (and bootloader most likely), then after the softdevice+bootloader running, updating the application.

It's just the DFU master make the process transparent as it's just one shot, but it's actually 2 connections under the hood.

When you change the softdevice, and if it's major change (from SD v3 to SD v4 for example) you need to update the bootloader as well, because old bootloader won't work on new softdevice.

@Nguyen Hoang Hoan: It's fine now to update major softdevice version as long as the MBR are the same. It was the limitation long ago where the location of the application ( size of softdevice) is hard coded in UICR.

You need to follow the instruction described in the link Peter gave you and the pc-nrfutil that you already know.

I am afraid you cannot upgrade major SD version. OAT allow allows upgrade minor version of SD only. For example upgrading (SD+APP+DFU) from SD 3.- to SD 3.2 is possible but not SD 3 to SD 5. A major update requires you to reflash the whole thing using a jtag.

Have you created a zip package according to this?
