Lumia 640. Win 10.0.14926.1000 . I looked for an update, got the message "cannot update blah blah..." Error 0x8024800a . I reset. Went through the whole hours long ordeal. To arrive at..... Same problem "cannot reset....error 0x8024800a" PLUS - now a number of the few apps offered wont work or install!!!!
Among them Whatsapp. It keeps asking if it can install on "C drive" saying it need someting like 30 megs and 3 GIGS are available on the "C drive" . I say yes install there.... same loop , same problem....
