Here is another Android 6.0 Marshmallow based AOSP ROM for the LG Optimus G. Following kevinjoa’s Marshmallow ROM, DevSwift1 has stepped into the development for this device. This is a Pure AOSP ROM developed from the Android 6.0 Marshmallow Open Source Code released by Google. This makes the ROM close to the other Nexus device firmware with the Software version 6.0.

Although LG G may not receive the latest Marshmallow firmware update despite its good hardware specifications, you can still install the custom ROMS we have been listing for the device on our portal. Being an AOSP ROM, it’s lightweight, minimalist and excludes all the unnecessary bloat and animations that we find in most stock firmwares. Apart from this, the ROM comes bundled with SuperSU, material design, and some tweaks for reboot options, init.d support and more.

To install this ROM, you need the compatible TWRP version installed on your device in order to flash the ROM that has been listed below. We have also listed some compatible Google Apps that have been fixed and tested on other AOSP ROMS for many devices including the Nexus series. So let’s begin with the tutorial.


  • Download | Android 6.0 AOSP ROM for LG Optimus G (File: (299 MB))
  • Download | Recommended Google Apps (Fixed for the ROM)
  • Download | Mini Google Apps for Android 6.0 Marshmallow
  • Download | lg-optimus-g-twrp-2.8.7-recovery.img


  • This is a clean AOSP ROM for LG Optimus G. Do not try it on any other device.
  • You need Recovery TWRP installed on your Nexus 4 in order to flash a custom ROM. To install the ROM, download this recommended TWRP version for your device from here. Install it using Flashify. For detailed TWRP installation instructions using fastboot, get to our tutorial through this link.
  • You must have device drivers installed on your PC so that you can transfer the ROM and Google apps to your device’s storage.
  • You must fully charge your device or at least to 60%, as the process may take a while.

Backup your Apps and Data

Before you proceed, make sure you backup all your data. This process will wipe all the data from your device except for the internal storage. Hence, a full backup or nandroid backup is recommended. Also backup all your internal storage files just in case anything goes wrong. Take a nandroid backup from the custom recovery before flashing the ROM.

Warning: Warranty may be void if you root or install custom ROM on your device. We at DroidViews won’t be liable for any damage to your device whatsoever. We are not responsible if you brick or damage your device. Reader’s discretion is advised.

Get Pure AOSP Android 6.0 Marshmallow ROM for LG Optimus G

  1. Download the AOSP ROM and the Google Apps from the download section.
  2. Now transfer the two zip files into your device’s internal storage. Place the zip file where you can easily locate it.
  3. Now reboot into Custom Recovery (like TWRP). To boot into TWRP, first turn off your device and then press and hold volume down and power keys at the same time.
  4. Although this is optional, it’s highly recommended that you perform a nandroid backup. To backup your ROM, tap on backup option in TWRP and select the following elements: System, Data, Boot, Recovery, EFS and swipe right where appropriate, to backup.
  5. After performing the ROM backup, return to the TWRP main menu and tap the wipe button and select Advanced Wipe. Then select Dalvik CacheData, and Cache. Now swipe the confirmation button to backup.
  6. Now go back to the TWRP main menu or home screen and tap on the install option. Navigate to the ROM file and select it.
  7. Swipe the confirmation button to proceed with the installation. The ROM will be installed.
  8. Now return to home in the TWRP and tap on the install option. Navigate to the Google apps zip file and select it.
  9. Swipe the confirmation button to proceed with the installation.
  10. Once installed, reboot to system.

When you see the boot logo, that means you have successfully installed the ROM on your device. If you come across any boot loop or face system errors, try a factory reset from the recovery or you can always restore your previous ROM from the backups.
