Hi guys. I own a 1020. Trying to update from cyan to dp gdr1 i m getting this error

801881e8

There is nowhere such an error... I m the first facing that or ms did something new with developers?

i tried with wifi, 3G, another wifi, soft resets, checked date/time and more. 3 days now keep getting this...
