Install Android 5.0.2 Lollipop On Galaxy Tab 2 P3100/P3110 Using CyanogenMod 12 Custom ROM

Galaxy Tab 2’s software life ends on Android 4.2.2 Jelly Bean. The device won’t be getting any further official Android updates because of its hardware limitations that make the device incompatible with any other Android version higher than 4.2.2 Jelly Bean. Users who want to run a higher version of Android on their Galaxy Tab 2 can do it easily using a custom operating system. There are quite many famous custom ROMs based on Android 4.4.2 KitKat and now on Android 5.0 Lollipop available for the device. The latest iteration in Android’s line is Android 5.0 Lollipop, so we’ve selected it to install on our beloved Galaxy Tab 2 for now.

We are going to install Android 5.0.2 Lollipop on our beloved Galaxy Tab 2 P3100 and P3110 using CyanogeMod 12 Custom ROM. Those who are not aware about the CyanogenMod custom ROMs, they may want to know that CyanogenMod is the aftermarket distribution of Android OS and happens to be the most popular and most widely used custom operating system. The ROM is available for almost all the device which have been forgotten by the device manufacturers in the software regards. The ROM we’re going to install in the on-going guide is stable, but it may not be kept for everyday use, and newbies are recommended to stay away from it. Let’s go through some quick early preps and then install it right away.

First boot may take up to 10 minutes, you may not worry if it’s taking that much long. In case it’s taking too long, you may boot into TWRP or CWM recovery and wipe cache and dalvik cache and reboot your device as it may fix the issue. In case your device is having issues, you may return to your old system using the Nandroid backup or follow our guide here to install stock firmware.

    • @disqus_cO2tZ9MMy0:disqus Clear the cache and dalvik cache of your tab, make sure that the USB cord you’re using works well and also make sure that your adapter is fine as well.
