R31.0.3-windows - Platform-tools
Version r31.0.3 is famous in the custom ROM community because it handles Seamless Updates (A/B slots) perfectly. Later versions (r32.0.0) temporarily broke the fastboot set_active command for certain chipsets (MediaTek and older Qualcomm). If you have a Pixel 3, 4, or OnePlus 7/8, r31.0.3 is frequently recommended as the "last reliable" build.
Some Windows antivirus software may temporarily flag adb.exe – this is a false positive. Add an exclusion for your platform-tools folder if needed. platform-tools r31.0.3-windows
Fastboot is critical for flashing custom ROMs, kernels, or unlocking bootloaders. With r31.0.3 on Windows, you avoid the "fastboot not recognized" error. Version r31
