Android Questions? Ask Android Device Experts for Answers ASAP
Hi, thank you for contacting JustAnswer.com. My name is Russell. I feel that your question deserves an answer, though you have evidently found a solution elsewhere.
If your download didn't start, but finally ran through, then that should have been simply restarted. A firmware download that has not even started you can interrupt without any ill effect, usually.
You would be welcome to return to ask another question here at JustAnswer.com... and no response to this whatever is required. Thanks.
