    I updated to Windows 7.8 this morning on my Lumia 800, and I absolutely hate it.

    I've tried using the restore to last point on Zune but it keeps saying that my phone cannot be restored.

    Is there a way to revert back to 7.5?

    have you tried to hard reset your phone first to factory reset and then do that?

    That's how I did mine...

    Well from having no lag and smooth buttery feel to lagging and stuttering I'm pretty sure that's why, I know that's my reason for going back to 7.5

    I'd factory reset the phone, remove some apps, block some background tasks, 7.8's not normally that way. My parents phone has 78 on the radar, smooth as 75...

    hey, try this :
    1. Disconnect the phone from the pc and switch it off.
    2. Now, press and hold the power button + camera button + Volume Up key and after few seconds you will be in the download mode.
    3. Connect the phone to PC and the zune will automatically detect and open restoration screen.

    You can flash back to 7.5 with nokia care suite. The software is still downloadable. When i search for an RM-801 with product code 059l9q7 I find 1750.0805.8773.12220. And it works, i flashed my old L800 back with it and it runs normal. And after that you can upgrade it with zune. Your own product code is on the sim tray, take it out and read it then fill it in the data package manager.
