I am trying to downgrade my EG-25 G firmware on windows 10. I get the following error on Qflash_V4.19 whenever i select the firmware downloaded from the link given below.
" No Key (json,blf) file is found, this zip file maybe a invalid zip or you downloadmode is not right, please check it".

Please try QFlash v5.4 again!
