I upgraded my OnePlus One smartphone from Oxygen 1.0.0 to 1.0.3, see Installing OxygenOS 1.0 on the OnePlus One Smartphone.
Download OxygenOS 1.0.3 from OxygenOS 1.0.3 with the latest Stagefright patches, and check MD5. Then upload the zip-file.
adb push ~/Download/ONE_12_A.01_150827.zip /sdcard/
It is stated in Oxygen 1.0.2 Release with Stagefright security patches that “If you are already on OxygenOS, this update does not require a reset.” I had to factory reset my phone as TWRP didn’t recognize the system partition; it was encrypted, although encryption in my previous efforts never worked. It looks like it worked for TWRP only.
Shut down phone, and reboot with power-button and volume-down pressed, boot into TWRP, select your image on
/sdcard. That’s it.
These are the versions displayed:
- Android version 5.0.2
- OxygenOS version 1.0.3
- Kernel version 3.4.0-perf-g2e81366, email@example.com #1
- Build date 27-Aug-2015
- Build number A0001_12_150827
Using OxygenOS 1.0.3 I noticed the following:
- Battery consumption is still high.
- It is no longer possible to initiate SIP calls with the build-in telephone application, although you may still receive SIP calls, see also shahazadkm in OnePlus forum.
- Apps apparently no longer install automatically after factory default.
- I didn’t try encryption as this was a fiasco in OxygenOS 1.0.0.
For an answer as why not update to a higher OxygenOS version see OxygenOS 2.0 Q&A:
As for all of you wondering when the OnePlus One will get an update to the latest OxygenOS version, the answer is that we are working on it but the official date is not quite set yet. Since 2.0 is optimized for Snapdragon 810, it will take us a bit of time to port things over. In the meantime, the OnePlus One will still be officially supported by CM.
The OnePlus One has a Snapdragon 801.
