Hi everybody! :) I have a wonderful Oneplus One 64 GB Sandstone Black version and recently I decided to install, via TWRP, Android Lollipop 5.0.2. Now, my problem is: I can't be able to upgrade my CyanogenMod version, i'm stuck on the 12-20150402-NIGHTLY-bacon. In the Upgrade tab I can find and download the last nightlies (from 20150403 to 20150409), but when I select "Upgrade and reboot" and the 1+ reboots in TWRP nothing happens.. I can see for a very short moment some process failing, then only the homescreen of TWRP. Could somebody help me? :confused:
