Thank you for the reply. If I had the nRF DK I likely would not have ordered the Thingy:52. I went with the T52 due to the following:

"The Nordic Thingy:52™ is a compact, power-optimized, multi-sensor development kit. It is an easy-to-use development platform, designed to help you build IoT prototypes and demos, without the need to build hardware or write firmware."

thinking that I would not need to write firmware or need anything else to use the available pins on the board, as stated in the users guide. It is also interesting that even creating prototypes and demos requires some other hardware, since the board itself cannot be programmed, without writing firmware. I will likely move to a different platform, and use this as a sensor node.

If you have a nRF DK with a segger chip you can use this as programmer. description here.

Ok, since the Thingy does not have any methods to upload the bootloader since the USB cannot be used to upload anything to the board, I would assume the only way to actually change the FW is to purchase the programmer. Which means the Thingy is actually locked off to regular individuals. Wish I had this response before spending time getting the FW compiled.

As stated in the comment you copied above: only way to unlock the bootloader is by flashing user's own secure DFU bootloader with user's own public key

So I'm afraid you need to recompile and program the bootloader including your own public key, so that you can create a valid signature for your FW.
