Thanks. I have installed ADB and fastboot drivers for Win from https://www.getdroidtips.com/how-to-install-adb-and-fastboot-on-windows/ I have installed according to the attachment. But is not recognized in Windows. I did reboot the system after installation but did not add any new env variable. H:\>fastboot devices -l 'fastboot' is not recognized as an internal or external command, operable program or batch file.
