The OnePlus One is a computer enthusiast’s phone. It’s the new Nexus. So it’s a shame that upgrading this phone to Lollipop hasn’t been as smooth as candy.
If you are in India, you are not even sure if you will receive the OTA update of Cyanogen OS 12S. The rollout is slow, and users get frustrated when checking for updates returns nothing. And OxygenOS might be the biggest mistake of all. To install the official Lollipop upgrade from OnePlus, you need to unlock the Bootloader, manually flash the custom recovery and then flash the zip file. You can also just root the phone while you’re at it.
It’s a good thing OPO has been set up as a geek’s phone. Can you imagine a Samsung or HTC phone coming out with such a terrible upgrade system?
But you want Lollipop. You need it. So you will spend few hours to get it. And honestly, you like this part a little bit. It gives you a strange sense of power. It makes you feel good about yourself.
Ok, so below you will find instructions and links to files for flashing OxygenOS (Android 5.0), CM 12S (Android 5.0) and CM 12.1 (Android 5.1). This won’t be short, so grab a coffee.
Choose, choose, choose.
1. Manually update to OxygenOS
OxygenOS is OnePlus’ official Lollipop ROM. But because it’s not Cyanogen, it can’t update OTA. Actually, there is no easy way to flash this thing.
While you don’t need root access, you do need a custom recovery to flash OxygenOS (because you’re currently running a CM restore and that obviously won’t work well with OnePlus). And you need to unlock Bootloader. That means all your data will be deleted.
All about custom ROMs: Take a look at the top three custom roms, what makes CM 11 great, and the tools that make the life of a regular custom ROM flasher easier.
I covered how to unlock OPO’s Bootloader and install custom recovery in the OPO root guide. The steps here will be the same. So click here and follow steps 1 to 4 and come back.
Step 1: Download the zip from here and extract it. You will find two files. Zip file with can flash finally the one you want.
Step 2: Copy the file to the root folder in OnePlus One.
Step 3: Now we will boot into TWRP recovery by holding the . key Power + Volume Down keys. I am assuming that you have now unlocked the Bootloader and installed the TWRP custom recovery.
Step 4: Before we start, let’s back up the current ROM. Clap Support then swipe to confirm.
Step 5: Now make sure that CM is gone before we install OxygenOS. Clap Wipe it off then swipe to confirm. This will do a factory reset.
Step 6: Go back and press Setting and click can flash zip the OnePlus file and swipe to confirm flashing. Once done, tap System reboot.
Your OnePlus One should now boot with a fresh install of OxygenOS Lollipop 5.0.
2. Manually Update to Cyanogen OS 12S (No Root Required)
If you’re tired of waiting for the Cyanogen OS 12S OTA to arrive, or if you’re in a country where you’re not even sure you’ll get the OTA (**cough** India **cough* *), why would you? does not update itself to CM 12S. Hey, it’s much easier than flashing OxygenOS, I’ll tell you that.
You don’t need to unlock Bootloader or flash custom recovery. You won’t even lose any of your data.
Step 1: To get started, first download the CM12S flashable zip from here and transfer it to your phone.
Step 2: To be on the safe side, back up all your important data before starting the update.
Step 3: Enter About phone and tap the build number seven times. Then go to Developer Options and from the top, activate Advanced Reboot.
Step 4: Press and hold the power button, tap restart and choose Restart recovery. You will now be rebooted into CM recovery.
Step 5: From here press Apply the update -> Choose from internal memory -> 0/ and select the CM 12S zip file. This will start the flashing process. It may take a few minutes.
Step 6: You will then return to the recovery menu. Here, select Wipe cache partition and then reboot the system.
You are currently running CM 12S.
3. Manually update to CM 12.1 (Need root)
If you want to skip the whole official process and just want the latest and greatest from CyanogenMod (which is different from Cyanogen OS), this is the way to go. In fact, this is the method I took.
For this you will need an unlocked Bootloader, a TWRP custom recovery and you will need root access. You can follow instructions on how to do that here.
Once you’ve done all that, we can flash the CM 12.1 custom ROM. Remember, when you flash a completely different ROM, your data will be erased.
Step 1: Download the latest CM 12.1 Nightly from here and get Gapps. Transfer both files to your phone.
Step 2: Press Power + Volume Up to boot into TWRP recovery. Here, press for the first time Support and swipe to confirm to backup your current ROM.
Step 3:: Now, we need to delete the current CM ROM. Clap Wipe it off -> High level wipe and choose Dalvic cache, System, Data And Cache. Swipe to confirm.
Step 4:: Go Backside. From the home screen, press Setting and select the CM 12.1 zip file.
Step 5: Now again go back and delete Cache And Dalvic cache.
Step 6: Go back Setting and this time flash the Gapps zip file. Once that’s done, just reboot the system.
