This short guide describes how to upgrade your OnePlus One Smartphone from OxygenOS version 1.0.3 to 2.1.4. In this case the initial version of your OS is of no relevant importance -- you can also upgrade from version 1.0.0, but see Installing OxygenOS 1.0 on the OnePlus One Smartphone and Upgrading from OxygenOS 1.0.0 to 1.0.3 on the OnePlus One Smartphone.
Before start we need adb and fastboot. On ArchLinux these programs are in android-tools:
1pacman -Syu android-tools
Copying the OS image to the phone takes almost three minutes.
1adb devices

3time adb push OnePlus_Bacon_OxygenOS_201601190107.zip /sdcard/

Upgrading from OS 1.0.3 to 2.1.4 is apparently not possible by using TWRP. OxygenOS 2.1.4 for the OnePlus One says [more_WP_Tag]
Please note you will lose all your data. Also, do not try to flash this build through TWRP. You will most likely lose your radio and IMEI which means a trip to our customer support.

In above listing adb and fastboot are Mac executables!
With all these prerequisites boot into OnePlus recovery (power-button and volume-down pressed) and proceed as follows (as given in [MAC] Flashing OxygenOS 2.1.4 on OnePlus One (dead link)): · Select the language of your choice · Select “Wipe data and cache” · Select “Wipe data and cache” again · Select “Yes” · Select “done” · Select “Install from local” · Select the OxygenOS zip that you downloaded and copied before. · Select “Yes” · Click “Install” · Select “Yes” · Select “Reboot” · Select “Reboot” again
I exercised "Wipe data and cache" three times. Only the last exercise was a success. The previous wipes just booted into my "old" OS. I have no idea why this happened. Sometimes perseverance pays off.
OxygenOS 2.1.4 features:
- Android 5.1.1
- 3.4.0-perf+OnePlus@ubuntu-56 #1 SMP PREEMPT Tue Jan 19 01:15:39 CST 2016 armv7l GNU/Linux
- A0001_12_160119 build number
See screenshot with the versions:
So far my experience after two weeks of usage is positive: the phone works flawlessly. Battery life is as before, i.e., the battery lasts for one day.
Unfortunately the problem with SIP got even worse: You could not call outside with OxygenOS 1.0.3; now you cannot even get called and have acceptable voice. The VoIP functionality in the phone is now completely broken. For "best" results I used:
- Make calls with: Ask first
- Use SIP calling: For all calls
See screenshot in "Phone account settings" menu:
If you rely on VoIP this OxygenOS release is not for you, or you have to install a separate VoIP app.
What is striking when you go to the settings menu is the so called "dark mode", which I switched off:
There is a new "Shelf" application from OnePlus which I first did not activate during initial configuraton, but later activated, just to see what it does:
"Shelf" is somewhat similar to Google Now cards but less fancy.
