"This device is already registered" — what the message means and how to fix it
Trying to add a device and the app says it already belongs to another account? Here is exactly what that message means, why it appears, and how the link is removed.
4 min readUpdated
You try to add your scooter, e-bike, robot mower or diagnostic tool, and the app stops you with a message: the device is already registered, linked to another account, bound to a different user, or belongs to someone else. It is the same situation behind all of these wordings — and it is fixable.
What the message actually means
Whatever exact words your app uses, it is telling you one thing: the device is still tied to an account that is not yours — almost always the previous owner's. The device paired to their account when it was first set up, and that link did not end when the device changed hands. The app is doing its job: it will not let a new person take over a device that still belongs to someone else's account.
Why a reset does not clear it
The obvious move is to factory reset the device, and it does not work here. The registration is held on the manufacturer's side, not on the device, so a reset wipes your settings but leaves the account link exactly where it was. A reset device can still show "already registered".
How the link is removed
It comes off through the manufacturer's own process, as the lawful owner — nothing bypassed, no account accessed. That is what we do. Start with the device's identifier, its model, and the exact message you are seeing.
Start a request and we review it first — you get a yes or no, with the price, before any work begins.
You do not need the previous owner or the original receipt. We act only for the lawful owner and decline anything that looks otherwise.
FAQ
Questions, answered.
What does "device already registered" mean?
It means the device is still linked to an account that is not yours — usually the previous owner's. The link has to be removed before you can add it to your own account.
Why does it still say registered after a factory reset?
Because the registration is held on the manufacturer's side, not on the device. A reset clears local settings but not the account link.
Can you remove the registration so I can use it?
Yes — we take the case through the manufacturer's own process as the lawful owner. Start a request with the device's identifier, model and the message you see.
Is a registered device stolen?
Almost never. It is usually a normal resale the seller forgot to unlink. We act only for the lawful owner and decline anything that suggests otherwise.
