Problem resolution
Step # 4: if it does not detect your device, go to Settings -storage and Access on your device and make sure it is set correctly either ' Windows ' to connect to Windows or ' connect to Mac ' for everything else.
Step # 5: don't click on ' Download All ' unless ' Device ' is set correctly. It should say ' Connected ' and NOT ' Above ' the Us. If your device is not connected, see # 4.
If your download is very slow or stop, you may want to use a Download Manager such as jDownloader instead. In this case, use the ' Grab ' Link instead.
Step # 6: If the installation does not work, make sure it's not the phone company. Your phone company may have a policy that is assigned to block the install.
Step # 7: If your phone feels the train after the install, it may be because you did not install the OS + Radio + Apps together. Install the OS separately can cause problems because your settings will not be migrated, if needed. This can be Your hose install fully so make sure you upgrade the file together.
If something weird happens if not during this process, please contact the developers with Your bug report so I can fix it.
