Got my 9.1 update last night on my S2 649. I ran slicer and followed the script which took about 20 minutes and it rebooted (I think before slicer finished) then had a screen that said it may be hours so I went to bed. Now it takes 3 or 4 times of "powering up/just a few minutes" to finally boot completely up and once it does, it will reboot in about 5 to 10 minutes. Where would I look to see what's causing the reboots?
