hi is there a way to load old firmware? go back to previous initials since assistants eliminated them, I found an old .rar file 300 but how can it load usb does not work
SOMETIMES you can load apk files which are the "modules" by pointing at them with a File Manager on Android devices. It will ask if you want to install. NOT all apk files will load that way.hi is there a way to load old firmware? go back to previous initials since assistants eliminated them, I found an old .rar file 300 but how can it load usb does not work

RAR files are a form of "zip" files. They are a package in which there might be an firmware file and maybe a readme or other text or document file. So you would need to UNpack the .rar file and see what's in there. It might have instructions.I have .rar files how do I insert it I want to understand if downgrade firmware works
