I keep getting this error which says, "boot certification vertify". when I try to go into recovery mode. To begin with, I have updated my vs985 to 5.01 lollipop and then I had my device rooted. From this I have tried using apps like Flashify or using adb to flash TWRP 2.8.6.1 touch recovery for vs985. When I flash it I then boot into recovery to see that boot certification error. Can someone please help me fix this? If you need any more info just ask.
