Hey guys developer of this ROM here and just wanted to let you know I will be checking all of our posts now and trying to help out so buckmarble doesn't have to handle it all himself
In regards to an OTA, if that were to happen you would need to sbf to stock and then take the update. By then I hope Maverick would be updated to run with the new OTA.
As far as safestrap goes please head guidot's recommendation. Safestrap is far superior to bootstrap and it IS the future of these locked bootloader systems. Do your research and learn how to use it, it will save you a ton of hassle and headaches, trust me
