I'm using a Lumia 1320 DP windows phone 8.1 update 1 .. Yesterday I got the cyan update after waiting so long .. But the problem is that every time I download the update it stops at 90% and give this error code (801882cb) I've tried like 20 times till now and every time I get the same error at 90% .. My internet connection is good so why is this happening and is there a solution??
