New Xenon claim problem

I bought two Xenon boards from Sparkfun maybe a year ago. They were laying in a box all the time. When I finally try to use them, I get a surprise. No Mesh, can’t claim them. They are useless.

Is there a way to use them through Web IDE just like any other board? I try to claim it with auth token I get on boxes and boards, but get the message “could not claim device”. I can not do it with my phone, because I don’t have any Mesh. Is there any way to use them like any other board, or I need to go with CircuitPython? If so, those will be my last boards I bought from Particle. Just to mention I send them an email two weeks ago, with no response.
