Its features include Dual-core 800 MHz processor with NovaThor U8500 chipset, 4 GB of internal memory, 768 MB RAM, TFT capacitive touchscreen with 480 x 800 pixels resolution, 5-megapixel camera with LED flash and many more. Besides, it was launched with Android 2.3.6 Gingerbread OS which was officially upgradable to Android 4.1.2 Jelly Bean OS.

After Jelly Bean, Samsung stopped further updates for this smartphone which disappointed many users. There was only one way to enjoy the latest OS on Galaxy Ace 2, which was flashing unofficial custom ROMs. Last year the Cyanogenmod community developed CM 11 custom ROM based on Android 4.4 KitKat OS, especially for Galaxy Ace 2 I8160 smartphone. So after the release of the latest Android 5.0 Lollipop, there were many hopes that this latest OS will be available for Ace 2 soon. But days passed by and there was no sign of any custom ROM till last month when a recognized developer from the XDA community launched the latest, stable and full functioning Android 5.1.1 based CyanogenMod 12.1 custom ROM for Samsung Galaxy Ace 2 I8160 smartphone. Here, we’ll discuss easy and simple steps on how to update Galaxy Ace 2 I8160 to Android 5.1.1 CM 12.1.

Steps to install Android 5.1.1 Lollipop on Galaxy Ace 2

Download both the zip package files in a folder on your PC. Do not extract them. Now connect your Galaxy Ace 2 to PC and copy both the downloaded files on your phones SD card. Safely disconnect the phone from PC & switch it off completely. Now you need to enter your phone into CWM recovery mode. Hence, press and hold the Volume up + Home button (middle button) + Power button together. Touch won’t work in recovery mode. Hence, use Volume keys for navigation and the Home button for selection. As soon as you land into recovery, firstly make a Nandroid Backup of your ROM. After that, navigate to the ‘wipe data/factory reset’ option and on the next screen select ‘wipe cache partition’ option. This will clear all the data & caches from your phones internal memory respectively. Now go to the Advanced option. Select Reboot Recovery option on the next page. Wait until you boot again into recovery. Let’s move to the actual Android 5.1.1 Lollipop based CM 12.1 ROM flashing process. Select the ‘install zip from SD card’. Then on the next screen select ‘choose zip from SD card’ option. As soon as you select this option, you’ll see all the data present on your phones SD card. Just select the CM 12.1 ROM which you’ve copied earlier using the home button. On the next page select the ‘Yes’ option to start the actual Android 5.0 Lollipop flashing process. It will take some time to complete successfully. So wait and be patient. Again select ‘wipe data/factory reset’ option and ‘wipe cache partition’. This step is must solve the boot loop issue. Similarly, flash the Google Apps (GApps) as you’ve flashed this Cyanogenmod 12.1 custom ROM. Just remember not to wipe data/cache after flashing them. Everything completes here, just restart your Galaxy Ace 2 by selecting ‘reboot system now’ option. Note that the first boot takes more time to start than usual. But don’t worry it’ll be normal after a couple of boots.
