Unable to register Mangoh Red on Airvantage


How is your step???

Removed device because firmware version error. Device will not register to my account now

did you find problem if register another device?

I only have the one device. I get Subscription not linked to system when trying to register it

then can you delete the device in system view?

I already deleted it. I want to add it back
