I was wondering if anyone can shed some light on this. I woke up this morning and did a factory reset on my kindle fire HDX. When I checked the device version it stated I was on 22.214.171.124.2 whereas before I was on the latest update. Not being one to pass up on opportunity I rooted the HDX and accessed the system and renamed the otacerts. Anyone have any suggestions on what to do next? I'm a big noob when it comes to this tab it's way different from the other tabs I own.
