LG G4 Android 6.0 Marshmallow latest update


How to Install CM 13 ROM on LG G4 H815

Earlier this month, the LG G4 recently started receiving the official CM Lollipop Nightly builds. Now, following the CyanogenMod 12.1 ROM, the G4 pockets two CM 13 builds as we write. The international H815 variant is the first device to have received this build. With time, more such variants will follow.
The support for the international variant of the G4 seems to be incredible. Earlier this month the device received an official update with build number H81520A based on the latest Android 6.0 Marshmallow firmware form it’s manufacturer. We also have a TWRP flashable zip file of the official firmware. You can find it at the bottom of this post.
CyanogenMod is known to build some of the best third party ROMS for Android devices. Nightlies are stable as they are being developed for a long time now. The best part about CM 13 ROM is that it’s light weight, fast and most importantly Android 6.0 Marshmallow based.
Besides the ROM, you will also find a new CyanogenMod custom recovery image file in the recovery. This is a new custom recovery from the community meant for easy OTA updates. However, TWRP will work just fine with this release.
For the latest updates stay tuned and let’s begin with the tutorial.

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.

  5. After performing the ROM backup, perform a full wipe. Return to the TWRP main menu and tap the wipe button and select Advanced Wipe. Then select Dalvik CacheSystemData, and Cache. Now swipe the confirmation button to wipe.
  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.
If you see the new 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 backup.
