Phone: Redmagic 8 Pro (12GB RAM / 256GB Storage) Condition: Never serviced According to the information provided by the previous owner: The phone has an unlocked bootloader (rooted), and the RAM has been optimized for gaming performance. Because the bootloader is unlocked, there are some issues: 1. Android updates are not available 2. The lock screen does not work at all However, the positive side is: 👉 Gaming performance is 10/10 (100%) with no issues. The seller told me that: If I want, I can lock the bootloader again, and then: The lock screen will work properly Android updates will be available But the problem is: 👉 I don’t know where or how to lock the bootloader. For this reason, I want to change the phone, 👉 and I am also interested in exchanging it with another mobile phone.
