Install Official Cyanogen OS 12.1 OTA Update on Yu Yureka/Yureka Plus

YU Yureka and Yureka Plus users can now enjoy Android 5.1.1 Lollipop and new features like Smarter Screen, Redesigned Launcher, etc. on their device. Yu Televentures has released Cyanogen OS 12.1 (based on Android 5.1.1) update for YU Yureka and its plus version. Users will receive the OTA notification for the update in the coming days

The Cyanogen OS 12.1 update (YOG4PAS3JM) for Yu Yureka/ Yureka Plus will fix many bugs found in the previous build, improves stability and increase security. The update will include an enhanced Thermal control feature, which will fix the Yu Yureka’s annoying over-heating issue.


Also, this update will include improved memory optimizations, better data connectivity and the Camera Next app is optimized for more battery and thermal efficient.

Other new features in Cyanogen OS 12.1:

a) Smarter Screen: LiveDisplay intelligently adjusts your screen based on environmental conditions.

To install Cyanogen OS 12.1 update on YU Yureka and Yureka Plus, first, check for the update by going to Settings -> About phone -> System update. If the update is available, just download and install the update. However, if you have not received the update for some reasons, you can install it manually by downloading the firmware.

Manually Update Yu Yureka/ Yureka Plus to Cyanogen OS 12.1

Note: The below file is an OTA update file. To apply the update, your device should be running on the latest version of Cyanogen OS 12.

1. Download Cyanogen OS 12.1 OTA update zip file [HERE] or [HERE] ( and transfer the update zip file to your phone’s internal storage.

2. Now, boot your Yureka into recovery mode. To do so, switch off the phone and then hold down the Volume up + Volume down + Power buttons at the same time

3. From recovery, select Apply update -> select the zip file you have transferred in step 1 above.

Once the flashing process is finished, go back to the main recovery menu, select the Reboot system now option and wait for the reboot process to complete (Source, 1, 2)

    • Kannan

      Jul 28, 2017 at 8:14 am

      I thought that you have tried Android 7.1.2 Nougat based custom ROM. Your issue may be due to outdated bootloader, so update the bootloader and try custom ROM. Also, let us know the exact error messages you have got.

    I have yureka plus 4.4.4 and yet I not got any system update. I rooted my device and now what I do for update phone.

    • Kannan

      Jul 20, 2017 at 8:41 am

      As CyanogenMod is dead you will not get the update. However you can install official firmware from Yu or custom ROM LineageOS (Android 7.1.2)

    I m helpless for install new 128 mb update I had download it lots of time but it is not install at my device. I had format my device two time but this problem is still facing. play store & many other apps are not run. please help

    • Kannan

      Feb 9, 2017 at 2:19 pm

      To apply the OTA update your device should be on latest version of firmware and meet certain requirements. I think the problem with Play store and other apps are not related with the system update.

          Yes, since it is a official CM release you can update your device with out root access

    • Kannan

      Dec 11, 2016 at 4:54 pm

      The mentioned file is OTA. Since it is very old, you have already got this update. If not, you need to download the full ROM from Cyanogen support and flash it manually

      • kamal

      To apply partial OTA update, your device should have on most recent update or you need to download and flash full OTA update or full ROM

          • Kannan

            Sep 6, 2016 at 8:51 am

            Check for update by going to Settings > About phone or download and install the ROM from Cyanogen Support page. Usually, new update will enhance device performance

      If you can boot into recovery, you can install the OS. Make sure that the battery is fully charged (at least 80%)

      Delete cache partition in recovery and then reboot your phone. If that not helped download full firmware from Cyanogen support page and flash it

      • Asif

        Jul 18, 2016 at 12:05 pm

        You say about this file official Cyanogen OS 12.1 (5.1.1) (
        Is it file flash ???

        • Kannan

          Jul 19, 2016 at 8:27 am

          The file mentioned in the above article is official OTA update (not full system image), which requires certain requirement on the device to install. If any issue updating your device, download full system image (fastboot or recovery image) from Cyanogen support page and flash manually

            Yureka Plus comes with Cyanogen OS. You can flash CyanogenMod with TWRP custom recovery

          • Harish

            May 27, 2016 at 1:44 am

            The mentioned file is incremental update, so your device should be running on the latest version of Cyanogen OS. Or you can install the full rom by downloading it from Cyanogen support page

    Will the previous ROM be removed on it own or will it take up some space?

    • Kannan

      Wiping cache partition won’t remove previous ROM. Required some technical knowledge on flashing ROM manually.
