Here is what I did to bring my Nexus 5 to version 2.0.4.13: - Download the magic-device-tool from https://github.com/MariusQuabeck/magic-device-tool because I'm lazy - Install Sailfish OS using the tool - Update to 2.0.4.13 using the instructions on this page https://wiki.merproject.org/wiki/Ada...for_hammerhead by replacing the RELEASE number Job done... but, the battery still drains at the same speed haha silly me ;-p I guess the way to go is to flash and patch as advertised on the first page of this thread if you are looking for less battery drain.
