This is not an question but a fix to the problem my sisters had. When she tried to transfer all the data from the other Phone it said it failed. What i did to solve this problem was just to remove videos from the phone. She have 64gb storage and didnt work before. According to my calculations was that you needed 20% (12.8) extra storage with no use. If now your phone doesnt start, dont worry, just wait some more. If you now have a 256 you need to get rid of 50gbs what i heard.

i heard another problem which was solved with taking the old sim-card from the old phone and putting it in the new phone.
