After having jailbroken give or take 20 phones with evasi0n 7 I have made some observations and these are the results: 1) If your phone is in a reboot loop, be patient, some iphones have taken up to an hour to realize they are working and going past the apple logo. 2) Sometimes holding home and power till the apple logo comes back helps, not always. 3) Hard resetting as stated in 2 is the worst way to turn off your phone if you want to avoid reboot loops. 4) Trying to hold power then volume up has 0 positive effects on getting your iphone to boot up. 5) Always power down via a method that isn't reboot, power off then power back on. 6) Be patient, its a frustrating process that takes a bit of effort, but hopefully a fix will be released for it soon. 7) If all else fails, dfu restore. This is a last ditch effort.
