How to Flash CM12S YNG1TAS17L on your OnePlus One

How to Flash CM12S YNG1TAS17L on your OnePlus One

Earlier this week, you might have heard that OnePlus One was pausing roll out for CM12S due to wanting to add an additional voice search feature. Then today, the roll out went back online, and it turned out that it wasn’t voice search at all that caused them to pause the roll out, but really just a bug in the OTA.

Every OnePlus One owner I’ve ever met (and I spend a lot of time in the forums. It’s a lot) hates waiting for OTAs. They make such a big deal about updates and then we have to wait weeks for them. Whenever I hear someone complain about waiting for an OTA, I always ask, why wait? Flashing an update on the OnePlus One is so easy, even for the beginnerest of beginners.

Now, if you’re looking to flash this update, you’re in one of three scenarios. 1) You’re on CM11S and you’re waiting for the OTA, 2) you’re on the first version of CM12S and you heard that there’s more features that you’re waiting on, or 3) You’re on OxygenOS and you realized that it sucks and want to go back to CyanogenMod.

Good news. All are easy. The following instructions apply to everyone.

  1. First, download the CM12S zip file to your phone from here. You can download directly from the link to your phone or you can download it from your PC and copy the file to your phone’s internal storage.
  2. Shut off the phone
  3. While holding the volume down button, press power to turn on the phone. Do not hold power past when you feel the phone vibrate because it will shut the phone off. This will boot you into recovery.
For CM Users
  1. You should be booted into Cyanogen Recovery. Select “Apply Update”
  2. Select “Apply from Internal Storage”
  3. Navigate to the file you downloaded and select it.
  4. Follow the onscreen instructions to set up the phone. Your data has not been erased.
For OxygenOS Users

Now, if you are running OxygenOS, you’ve flashed before, which means you’re running TWRP recovery.

  1. The first thing you need to do is wipe your phone. If you don’t do this, CM12 will install but there will be lots of errors.
  2. Once you’ve wiped your phone, select Install
  3. Navigate to the file you’ve downloaded and select it.
  4. Swipe to confirm the flash and follow the instructions to set up your phone.

Once it’s all said and done, your OnePlus One will boot as normal; however, at some point you’ll get a notification (within a couple minutes of booting it up) to set up the voice commands.
