Optimus_Robertus, Jun 23, 2018 : Hi all, I would like to flash AOSP Extended v5.6 (18-6-2018 version). However, in the XDA thread, it says firmware 5.1.2 is required. What does this mean? Does it mean I have to flash OOS 5.1.2 first, before I flash this ROM? At the moment, I'm on Open Beta 12 (NoLimits), so can I flash this ROM, without first flashing OOS 5.1.2? Thanks in advance!
