Q：The computer requires a password to boot.
A：1. A PIN code (lock screen password) may be set in the system, requiring you to enter it to unlock. If you've forgotten your password, you can try entering Recovery Mode by simultaneously pressing the power button and volume up button while the device is powered off. Select "Wipe data" to clear the lock screen password and other data. If you cannot enter Recovery Mode, the only solution is to flash the ROM.
2. When the device detects a saved PIN code on the SIM card, it requires you to enter that code to access the interface upon startup. This is a protection mechanism for the device and SIM card. If you have set a password for the SIM card, you will need to contact your mobile carrier for assistance.
