I know I ask a lot of questions and it's because I am very cautious when it comes to expensive devices... Is this a good tutorial?
The last time I had help from a former friend doing this whole process took 4 hours. Will this take at most 1 hour?

Well if I start over, is the backup pretty much useless? Should I format or clean the SD card before proceeding?
