Fix: On Android 11 (2021), Google broke USB accessory mode for internal fastboot. You must use:
adb reboot bootloader
# Then connect via OTG cable, OR use simulated fastbootd:
adb reboot fastboot

#MAGISK
The effort to download, compile, and package ADB and Fastboot using the Android NDK into a Magisk module represented a convergence of several advanced Android techniques: cross-compilation with NDK, systemless modification with Magisk, and deep understanding of Android’s boot and debugging architecture. In 2021, this enabled a new class of on-device recovery and flashing workflows, reducing PC dependency for developers and power users. While official Platform-Tools remain the standard for PC-based debugging, the NDK+Magisk approach illustrates the flexibility and openness of the Android ecosystem for those willing to venture beyond conventional boundaries. download adb fastboot for android ndk magisk module 2021

This guide explains how to compile static ADB and Fastboot binaries using the Android NDK (r22 or earlier, 2021 stable) and package them as a Magisk module.
The module installs the binaries to /data/adb/modules/adb_fastboot/system/bin so they are available system-wide in rooted Android environments.
To build ADB and Fastboot for an Android Magisk module in 2021, the typical workflow was:
# Install NDK (e.g., r22 or r23)
# Set environment variables
export NDK=/path/to/android-ndk-r23b
export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/linux-x86_64
export TARGET=aarch64-linux-android # for 64-bit ARM
export API=21
