Android 4.3 Jelly Bean via Cyanogenmod 10.2 on LG Optimus 2X P990 [CM10.2]

LG Optimus 2X is the first mobile in the world with dual core processor. Officially it has been updated to 4.0 ICS from 2.2 Froyo. Unfortunately it never updated to it Android 4.1 Jelly Bean. And with the release of Android 4.4 Kitkat, it is very unlikely that LG will announce any update for it.

Still there are some other ways to get this update that is flashing the custom ROM. Cyanogenmod 10.2 (CM10.2) custom ROM which is based on Android 4.3 is recently compiled for LG Optimus 2X. Though Android 4.3 is a minor improvement over 4.2, you will come across few new features like improved camera app, graphics, better location detection, improved keyboard, Bluetooth smart support etc. For perfect AOSP experience, Cyanogenmod is best of all.

You will also get typical Cyanogenmod tweaks. However this ROM is in alpha state, so it might happen that you may come across few bugs. All the bugs from CM10.1 are still there in this update. But since these bugs are negligible, you can go for it.

Follow few simple steps written ahead to install Android 4.3 Jelly Bean via Cyanogenmod 10.2 (CM10.2) custom ROM on LG Optimus 2X P990.

Pre-requisites

  • Charge your mobile at least up to 75% before executing the steps so that procedure won’t get interrupted.

    I have done this to my phone and it is not working. It is stuck at the boot screen and is displaying two LG logos next to each other towards the top half of the screen. Any help, even a point towards stock ROM would be appreciated.

  • Bigfoot

    I just installed this and it seemed promising. But there is a showstopper – the camera is not working at all. The camera app says that it “can’t connect to camera”. I tried some other camera app, but they all crashes or stops responding. I tried an additional factory reset but that didn’t help.
    Is this a known bug or does it only happens to me?

    • Viraj SK

      It’s a bug.

  • Karan

    Even after following all the steps properly my LG OPTIMUS 2X P990 is not booting up. Boot Loops. please help me. reply

  • http://www.denisgottardello.it mrdebug

    Ok, I have downloaded the 2 packages but now is impossible to go to recovery mode. Rom manager says that there is a problem flashing your mobile. Is impossible to reset the mobile to factory default and holding power button – volume has no effect.
    Can you help me?

      • Jubair Siddeeque

        Thank you Abhijeet.
        Is there an option to change the primary storage card as it was in a 10.2 build?

  • Marco

    Uhm, I don’t get it. The CM installation runs perfectly, but when I try to install the latest version of GApps, it gives me a fatal error and it stops. If I start the phone up and go to System info, I find that both the CM and the android versions (respectively 10.1-20140105-NIGHTLY-p990 and 4.2.2) are the same as before the installation. What shoult I do? Tanks
