i was running rubix 1.9 off of system version 2.3.15..i wanted to try fabulous new rom but i needed a new system version to do so..so the easiest way i knew how was to flash back to stock using a sbf file with rsd lite,install the new ota update of .340,reroot my phone then install apex...so all that worked..liked the rom but not running to stable on my phone,so i installed the zip for rubix 1.9 back on my phone and it downgraded the system version back to .15..any ideas why this happened?thanks
