I am currently using twrp 2.2.2.0 recovery on my Xoom WiFi. I would like to upgrade to twrp 2.3.3.0. I have found twrp 2.3 wingray zip. Can I flash the new twrp zip over the older twrp or do I need to wipe anything first? Am running jelly bean based cm 10.1 ROM. Any input would be greatly appreciated. Thanks!
