The Redmi 4A (rolex) is powered by a Qualcomm Snapdragon processor, not a MediaTek chipset. This means the process for unlocking the bootloader unofficially will differ from MediaTek devices. Unlocking the bootloader without a Mi account on a Qualcomm-based Xiaomi device is risky and may void your warranty or brick your device. However, if you still want to proceed, here’s an unofficial method using Qualcomm tools.
Prerequisites:
- Backup Your Data:
- Unlocking the bootloader will erase all data on your device. Backup your important files.
- Install Qualcomm Drivers:
- Install Qualcomm USB drivers on your computer to ensure proper communication with your device.
