Reclaiming Used Particle Boron Batch

Hello, I purchased roughly 30 devices from a company that closed their doors. The previous owners did not disclose any information or release any of the devices. i have all of the boxes and im able to connect and pull the imei, device ids. but i am unable to claim or unclaim them. i need to start a support ticket to reclaim these used devices. Unless there is another method? They have been inactive over a year. If the used product works i plan on buying 5g/ sattelite dev kits in bulk within the year. Just wanting to test on my project.

Can you please DM me the device ids? I'll see what I can do.
