If you don’t care about the data on your device you can now find Windows Phone 7.8 ROMs on Navifirm for Nokiaâ€™s full range of Windows Phone 7.5 handsets, including the Nokia Lumia Lumia 510, 610, 710, 800 and 900.
The firmware is available for most European countries and APAC variants . It includes Microsoftâ€™s Windows Phone 8 updates, but none of Nokiaâ€™s exclusive features.
If you are brave and reckless, here is a guide for flashing the firmware. Everyone else should hang on, as the arrival of the software for all devices is a clear sign the software will be pushed out to devices pretty soon.
