Because Android is communicating natively with another Android device over USB, configuration glitches can occur. Here is how to fix hot issues: "Permission Denied" or No Devices Found
A data-capable USB OTG adapter or a USB-C to USB-C cable to connect both phones. 2. Software & Settings Preparation
Method A — Unlock via fastboot from Termux (device supports fastboot mode and USB OTG with host capability)
Standard android-tools in Termux typically require root permissions to interact with physical USB-OTG architectures. To bypass this restriction, install a specialized library that routes ADB commands through the standard termux-usb wrapper: unlock bootloader using termux hot
The waiting period is a security measure from the manufacturer. Unfortunately, it cannot be bypassed. The best course of action is to wait the required time and then run the unlock command again. Do not remove your account from the device during this time, as doing so may reset the waiting period counter.
Require linking an Mi Account in Developer Options, waiting a mandatory holding period (often 168 hours), and using specialized unlocking tools. Community-built Python tools can sometimes run in Termux for this purpose, but they require account tokens.
You cannot use Termux installed on a phone to unlock that exact same phone's bootloader. Software & Settings Preparation Method A — Unlock

Your target device will likely prompt you to confirm the action. If successful, the device will reboot and perform a factory reset.
