Enable 1080p HD Video Recording On LG Optimus 2X And G2x [How To Tutorial]

In case you opted for an LG Optimus 2X or G2X, then there is some great news for you. Senior XDA member and Android developer LeJay has managed to mod the native camera to record 1080p at 30 FPS HD videos on these devices.

The mod actually replaces your genuine / stock Camera.apk with a customized version that unleashes true potential of Tegra 2 Processor. For the time being, this mod is only applicable on rooted Optimus 2X / G2x running CyanogenMod 7 Nightlies.


This modified camera application for Tegra 2 processor based phones also comes integrated with an updated media_profiles.xml responsible for enabling different Bitrates in a user friendly manner. And if you have already deployed the famous 64 MB RAM hack for G2x / Optimus 2X, then you will either have to disable it or get rid of it in order to let this camera mod function properly. The development so far has been great and I believe that this hack soon will be integrated in other Tegra 2 phones but for the time being, do not try this on any other handset except LG Optimus 2X / G2x. Currently there are 5 builds available with each one of them offering different recording capability at compatible FPS rate. The FuLLHDMod_High 1.0 provides you with HD: 1920×1088 @30fps @26mbps High: 1280×720 @30fps @12mbps, but needs a faster SD Card to handle the processing etc.

Here is a FAQ regarding this mod direct from developer:

Q: Does this work for non-CM7 ROMS?
A: Probably not. Certainly not froyo. But feel free to try and let me know. On stock rom-based builds, please look at somemadcaaant’s awesome work at http://forum.xda-developers.com/show….php?t=1090785.
Q: T-Mobile LG G2x support?
A: Yes.
Q: What are the disadvantages?
A: Larger file size. Takes longer to save (give it time to save before doing anything else with the phone). Potential issues with playback on phone.
Q: Does this work with 64 mb ram hack?
A: No. You can still use a high bitrate 720p mod for that kernel, though.
Q: It stutters after a few seconds of recording or freezes once in a while, why is this?
A: Your phone/sdcard is having issues trying to keep up. Try a lower bitrate mod. If there is no lower, ask for one. I’m experimenting a little myself, trying to find a stable bitrate.

So let’s see how we can enable 1080p HD video recording on Optimus 2X / G2x:

  1. The first step is to make sure that you have root on your phone along with CM7 Nightlies installed. You can head to Optimus 2X CM 7 Nightly thread or click here for G2x.
  2. Once you are done installing CM7 on your phone, head to the XDA thread here to download Full HD Mod version according to your choice and device’s hardware compatibility. You will also see files named:  BitrateMod(720p only)-signed.zip and Autofocus1.1-signed.zip. You can also download these files to enable BitrateMod and Autofocus after you have deployed the Full HD Mod.
  3. Once you have downloaded the files needed, connect your phone to the computer via USB cable and copy all the zip files to SD Card root.
  4. Although not necessary, but it is recommended to make a backup of your current Camera.apk file using Titanium Backup or an app of your choice.
  5. Now reboot your device into Recovery Mode. You can do it manually using the correct button combination or use ROM Manager’s simple Reboot To Recovery option.
  6. After you are in Recovery mode, navigate to Backup / Restore and make a complete Nandroid backup. Again, this isn’t necessary but I want you all to be safe if things don’t work out as planned.
  7. Once done, go to Recovery main menu and navigate down to Install Zip From SD Card.
  8. In the resulting menu, select and install Full HD Mod Zip file you copied to SD Card root.
  9. After the installation is complete, install BitrateMod and Autofocus 1.1 zip files respectively.
  10. Now reboot your device.
  11. Once your device reboots, tap on Camera icon and see if you are able to record 1080p HD Video.

If you are facing any issues with this procedure or Camera.apk is force closing on you, then I will suggest to consult the XDA thread link provided in step 2. You can also see 1080p in action on dev’s official YouTube Channel.
