Dear,,,
- download WindowsDeviceRecoveryToolInstaller.exe, to install drivers.
- download the OtcUpdaterZip.exe if unable to use it use winrar to extract it to a folder and name it c:\wp
- run the otc tool from the directory that you creat it once is running connect your phone wait untill updated
- restart your phone couple of times untill the final version is installed.
note that 've been using MS products since the early 90s and they are simple as solitaire so kindly do as advised and every thing will be done and more than fine and okay after the final update is installed you may go to the store and use your applications as you want today is July 7th 2020. i bought the Lumia 540 in june 2020 and it is running great
