It seems to be used free fall down !!
As you see the picture, all landing gear doors still opened even L/G down.
that means could be empty of green hydraulic fluid due to engine burst. As you know A380 hydraulic system powered by 5000p.s.i. so, if engine driven pump line damaged then just takes few minutes to make empty reservoir.
Nose and wing L/G system operated by green hydraulic system and main L/G operated by Yellow system.
