I'm on a Lumia 635 with OS version 9941.12498. I've been on the Windows 10 Technical preview Slow Track and a few weeks ago the phone notified me that there was an update however there wasn't enough space on the phone. I moved a huge amount of apps over to the SD card and began the download. I've tried many times and have also received the error code 800b0100. Phone free space is at 1.91GB.
I don't wish to use the recovery tool because my backup does not work. It encounters an unknown error every time. Thanks.
