cambium wireless acess point device unclaiming , claiming , onboarding

if your cambium device was original setup under someone else's account, and you are the owner, you want to manage your owner device,
you created your own login / network / onboarding key
you enter the s/n to the portal

you need to provide docs to Cambium to prove you are the owner

maybe after a long while, someone unclaim it from the old account, you onboard to the new one

it may not show up ,  I will have to manually enter the device 192.168.0.1 admin / ad

manually enter
cambiumID
onboarding key
url
cloud.cambiumnetworks.com

in this case , I can see the firmware updated during the onboarding process
