Is your NS hacked or is the original unhacked?
1. The original is not cracked: After charging for a short time, press the power button for 15 seconds, force a restart, and see if the battery icon appears.
2. Cracked version: After charging for 2 or 3 hours, charge the dongle for a minute, and then press and hold the power button and the key can be turned on, and then every time you shut down or no power, you need to turn on.
Both of the above still can't solve the problem, just go fix it!!!
