    I have a Lumia 620 running Windows Phone 8.1 (Lumia Denim). I am trying to update my phone to the latest version of the Windows 10 Mobile Technical Preview, but I am having no luck. I've tried both the fast and slow rings, but after it updates, it tells me that there was a problem updating and gives me the error code 80070020. Anyone have any advice? I had some issues with making room in my phone's storage, but I was able to clear enough space by clearing caches and temporarily files to install the update. I really don't know what to do next...

    If you really want to install the W10M, minimum 1.5 gb free space required to smooth install..
    Better wait for next build and Remember after installing TP "Hard Reset "will give you the true picture of TP..
