We should add to the tutorials that for the 7+, you should reinstall cydia substrate first thing to stop the respring/reboot problems. Once that gets done, everything is steady freddy.
So others had this issue? I thought I was just unlucky.
Mine's been fairly smooth, no random reboots yet since I reinstalled cydia substrate. Although my iPhone runs hot now, it never ever did that before, kind of makes me nervous.
