I understand your frustration with the bike computer not picking up data after re-inputting all the information. It seems like a common issue, and I have a few suggestions that might help.
Firstly, ensure that the bike computer is properly connected to the sensors. Sometimes, re-pairing the device with the sensors can solve the problem. You can do this by resetting the sensors and then re-pairing them with the bike computer.
Secondly, double-check the battery contacts to ensure they are clean and making proper contact. Corrosion or dirt can interfere with the connection and cause the device not to pick up data.
Lastly, if the issue persists, you may want to consider contacting the manufacturer's customer support for further assistance. They may have specific troubleshooting steps for your device.
I hope these suggestions help, and I wish you the best of luck in resolving the issue.
Best regards,
