If none of the above work, the components inside your reset button on the side of the unit are probably too corroded. You’ll need a replacement part, which Withings won’t send you. This is a basic design error that Withings are ignoring. This is the 2nd product I’ve had design issues with. Take from that what you will but this user will never be buying from them again.
A headcount for all the connectors that need to be exposed when reassembling would be really useful here. I count 15. If you have less you’ve missed something.
