Earlier, I already showed you how exactly to install a 3rd party custom ROM called ‘LITE custom ROM v3.6’ on Alcatel Flash 2, which is actually the light version of stock Android Lollipop OS that comes with the phone out of the box.

Anyway, besides the LITE stock Lollipop custom ROM above, there’s actually another custom ROM that is also compatible with Alcatel Flash 2. And this one is called ‘CyanogenMOD 12’, which is still based on Android Lollipop 5.0 OS.

Well, if you’re interested to try out this custom ROM on your Alcatel Flash 2, below I’m about to show you how exactly to install CyanogenMOD 12 custom ROM on this phone.

WARNING!! Do this at your own risk!! I will not be responsible for anything wrong that might happen on your phone!

#1. Root your Alcatel Flash 2

Okay, the process of installing CyanogenMOD 12 OS on Alcatel Flash 2 is actually similar with the process of installing the LITE custom ROM v3.6.

So first of all, of course your Alcatel Flash 2 must be rooted by using Kingroot app. But if you have rooted this device, then you can just proceed to the next step.


#2. Download CyanogenMOD 12 custom ROM

The next thing to do now is download the CyanogenMOD 12 custom ROM that is compatible with this phone. This custom ROM is still based on Lollipop OS by the way. But hopefully, the new CyanogenMOD 13 (Android Marshmallow OS) will arrive soon on this device.


#3. Download TWRP (recovery tool)

After downloading the custom ROM, the second file you also need to download is TWRP, which is a custom recovery tool (like ClockWorkMod). This tool will be important later if you want to backup the system of your device and also flash the new custom ROM, or in this case, CyanogenMOD 12 OS.


#4. Transfer downloaded files to internal storage

Once you have finished downloading 2 files I mentioned above, now transfer them both to your smartphone, either internal or external SD card. But DO NOT extract these files. Just leave them untouched as zip/rar files.

#5. Download ‘Rashr’ to install TWRP on your device

Now unlock your smartphone and open your Google Play Store app. And then find an app called ‘Rashr’. This app requires root access on your phone by the way, which is why I already asked you above to root your phone.

After that, install the TWRP image file you downloaded earlier by using this Rashr. But if you don’t know how to do that, you can check out my old post that covers this topic.

#6. Backup your media files

It’s really important to backup your media files such as: videos, photos, mp3s, etc before installing the custom ROM because once you’ve finished installing CyanogenMOD 12 OS, your microSD card needs to be formatted in that new OS. Otherwise, many of your files might be deleted randomly by the new system.

So if you have many important videos, photos, mp3s or documents on this phone, I suggest you to transfer them to your laptop. Later, you can put them back in AFTER your microSD card has been formatted in the new CyanogenMOD 12 OS.

#7. Backup your apps/games along with their saved data

After backing up your media files, you may want to backup some important apps/games along with their saved data. To do that, you can use an app called ‘Titanium Backup'.

So later, once your phone is installed with the new custom ROM, you can restore all of your apps/games along with their saved data back into the phone.

I always do this every time I want to install any new custom ROM on my Alcatel Flash 2 in order to save some important apps like Mozilla Firefox, Opera and Opera mini along with the bookmarks, history list, passwords, saved pages etc.

#8. Remove your SD card

Okay, after backing up your apps/games and media files, now remove/unmount your microSD card out of your phone. But DO NOT put it back in BEFORE your phone is installed with the new CyanogenMOD OS.

#9. Your tablet must have sufficient storage and 50% of battery life

Before proceeding to the process of installing the new custom ROM, first make sure that your Alcatel Flash 2 right now has around 50% of battery life. This is really important to prevent anything bad during the installation process, so you can still fix your phone in sufficient amount of battery life.

Also, your phone needs to have a sufficient amount of storage space because it's gonna be important for the next steps.

#10. Go to recovery mode (TWRP)

Now it’s time to go to the recovery mode (TWRP). To do that, now open ‘Rashr’ app and then select the option ‘Reboot to recovery’.

#11. Create the backup system using TWRP

Before installing the new custom ROM (CyanogenMOD 12 OS), it’s really important to create the backup system of your device first. So if anything bad happens, you can still restore this ‘backup system’ and your phone can still be turned on normally without any problem.

To do that, select ‘Backup’ > and then, in ‘Select Partitions to Backup’, give check mark to all small boxes on the screen > choose the storage to backup > and finally, slide the toggle that says ‘Swipe to Backup’.

IMPORTANT NOTE: This 'backup system' will be removed automatically by TWRP if you use it to restore your phone back to normal again.

#12. Select ‘Wipe’ and ‘Swipe to factory reset’

Once the process of backing up is complete, now go back to the first screen of recovery mode > select ‘Wipe’ > and ‘Swipe to factory reset’.

#13. Select ‘Install’ and locate the custom ROM

Now it’s time to install the new CyanogenMOD 12 custom ROM. To do that, go back to the first screen > select ‘Install’ > locate the CyanogenMOD 12 file you downloaded earlier > and ‘Swipe to confirm Flash’.

#14. Wait for a few minutes until the process is complete

The process of installing the new CyanogenMOD 12 custom ROM usually takes around 2 minutes to complete. Once it's finished, press 'Reboot to system' to restart your phone and enter to the new system.

Once your phone is rebooting, your will then be shown with the boot animation of CyanogenMOD OS for around 15 minutes.

During this process, I suggest you NOT press anything on the screen. Just leave your phone on the table.

#15. Enter to the homescreen

Once the installation process of CyanogenMOD custom ROM is finished, you will be brought to the homescreen. As usual, before being able to enjoy the new OS, the system will ask you to enter your Google account and configure the main settings like: time/date, language, etc.

#16. Your Alcatel Flash 2 has been installed with CyanogenMOD 12

As you can see on the screen, after entering your Google account and configuring the settings, you will then be shown with the homescreen for the first time. This means, your Alcatel Flash 2 has been successfully installed with the new CyanogenMOD 12 custom ROM. Congratulations guys!

Conclusion

Well, there you have it guys, my step-by-step guide for you if you want to know how to install CyanogenMOD 12 OS on your Alcatel Flash 2 smartphone. Hopefully, this guide works perfectly on your device.

I know that this custom ROM is not any good compared to the stock OS that comes pre-installed on this phone. But if you want to try out something different with your device, then CyanogenMOD 12 OS can be one of very few choices out there.

I actually never use this custom ROM because it doesn’t support USB OTG (on-the-go). So you won’t be able to transfer your data to your flashdisk or the other way around if your phone is running on CyanogenMOD 12 OS.

Anyway, there’s actually another custom ROM that in my opinion is so much better than CyanogenMOD 12 OS above.

And that is the LITE custom ROM v3.6, which is the light version of stock OS that comes pre-installed with this phone. But I really like it because it offers many great features than the stock OS of Alcatel Flash 2.

So I believe you will feel the same way about this custom ROM once you get to try it.
