    Hi All having a pretty serious issue with a lumia 520 since giving WP 10 TP a try out... basically I left it installing overnight and the next morning it was stuck with the cogs going and rebooting over and over, thinking something obviously went wrong with the install I eventually managed to flash it back to win 8.1 the intention of trying again. All seemed fine I downloaded insider preview selected fast ring etc but when trying to download the update it error'd... then it really got fun.

    Now all apps crash the phone when opened, settings aren't being saved ( like date / time or to use the SD card when turned on ) and not receiving any SMS or calls. I'm also unable to flash the phone again, trying gives an error. It's as if the phone has been write-protected or something - I can view settings pages that only seem to display info like the about page, but anything that might need to save anything crashes.

    Any suggestions?

    Did you already do a hard reset?

    If a hard reset won't work, you could try to use the "Windows Phone Recovery Tool" on your PC to re-flash your phone with Win 8.1. Sorry, I can't post any links yet...

    Edit: This will do the trick (just copy&paste):

    Wow, this is really bad. I don't know any other method of "low-level" reset than the recovery tool.
    Did you try it more than once to reset the phone?

    Edit: did you try to remove the SD and SIM card and hard reset?

    yes tried several times resetting, but not without the sim i'll try tonight. I'm wondering if the win 10 TP installation puts it in this mode, and the phone is expecting win 10 to be installed hence the error trying to flash 8.1 again? just a thought.

    No, with the recovery tool on PC the phone is completely reset, a new Image is downloaded (hence this procedure will take a little longer than just a hard reset) and flashed onto the phone.
    There should really be no leftovers from Win10TP.

    But after flashing, I started the process on win 10 TP again and it's only when it tried to install win 10 the second time and gave an error that these issues started...

    Never managed to get this working again, turns on but still crashes and reboots when any app is opened or wen tryna update... Perfect timing though as my contract was up for renewal so now have a shiny new 640 :D ( and no, TP is coming nowhere near it lol )
