Windows 8 - Safe mode

Safe Mode is a great way to get into your system when something won't allow you to start up normally. Troubleshooting becomes a breeze when corrupted drivers and files aren't loaded that prevents a system from functioning. It used to be as easy as pressing F8 when the system starts up, but doing so with Windows 8 will take you to Automatic Repair Mode. The trick to getting back to good old fashioned Safe Mode? Hold down the Shift key and press F8 while booting up.

This takes you to the Recovery mode. Select "advanced options," then "troubleshoot," then the "advanced options" again (there are a lot of advanced options). Select Windows Startup Settings and finally the Restart button. This will reboot the computer and give you the option to boot into Safe Mode.

If you need to get into Safe Mode from within Windows, open the dialog box (the Windows key + R) and type "msconfig" (no quote marks). Select the Boot tab and check the Safe boot box. The system will continually boot into Safe Mode until you go back and uncheck the box.

Comment your workaround below, mine is the first one. If you are still on Mavericks, be there till Apple provides a fix for this.

Nexus 5 : IMEI 0 issue
