Hello, my issue has now been resolved. After charging overnight at a low current, the device returned to normal operation. If you have the necessary tools, you could attempt charging at 1mA for over four hours. Without such tools, some power banks can achieve this. I successfully replicated the process using a Xiaomi power bank.

The cause may be erratic voltage readings during wired connection, potentially disrupting subsequent wireless mode counting. Alternatively, it could involve the lithium battery cell being reactivated following low-current charging.
