The ports of the CyanogenMod’s latest source code has been trending in the Android community. A lot of devices have been receiving the CM 13 port based on the latest Android 6.0 Marshmallow version that was recently released by Google. One such device is the Samsung Galaxy Ace 3 LTE and some of it’s variants. While the Nexus devices have received official Marshmallow updates, CM 13 seems to be the only way to get to the latest Android software for the mid-range devices like Galaxy Ace 3.

Moreover, it’s not an official release from CyanogenMod community and hence, users may expect some bugs. The port is at it’s initial stages and with further development, stability improvements and bug fixes can be seen. The CM 13 source code has been recompiled for the Ace 3 device and some basic functions can be seen running perfectly on the device.

However, in order to install the ROM, you will need to setup TWRP onto your device and then flash the ROM and Google Apps simultaneously. As we have already covered the TWRP installation guide, it won’t be a problem. Just install the latest available TWRP build else there is a risk of bricking your device.

To be sure, backup everything before you proceed. This may include the apps, media, documents and all of your internal storage just in case anything goes wrong.

How to Install CyanogenMod 13 on Samsung Galaxy Ace 3 LTE

  1. Download the Marshmallow CM 13 ROM from the download section. Also download the Marshmallow Google Apps of your choice.
  2. Now transfer the zip file 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. If you see the TWRP logo, that means you have successfully booted into the recovery.
  4. It’s highly recommended that you perform a nandroid backup. To backup your ROM, tap on backup option in TWRP and select all the partitions including System, Data, Boot, Recovery, EFS and swipe right where appropriate, to backup.
  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.
