Samsung Galaxy Note 4 to Android 5.1 Lollipop With Unofficial AICP Custom ROM

Samsung is currently rolling out the Android 5.0 Lollipop update for owners of the Galaxy Note 4 in a select few regions, with more regions expected to receive the update in the coming weeks. While you wait for the Android 5.0.2 Lollipop update to arrive on your Galaxy Note 4, developers on XDA have already developed an Android 5.1 Lollipop based ROM for the Galaxy Note 4. The first to offer Android 5.1 Lollipop is the Unofficial Android Ice Cold Project Custom ROM meant for the Samsung Galaxy Note 4 SM-N910F and SM-N910G Qualcomm Snapdragon variants. If you own the Exynos 5433 powered Galaxy Note 4, you should not flash this ROM on your device as you will end up bricking your device. The Unofficial AICP ROM for the Galaxy Note 4 comes from Team Emotroid comprising of XDA recognized contributors aukhan, kabata, Pafcholini, and Jcanonico as main contributors. The ROM is based on AOKP and offers a number features and improvements that you won’t find with stock Android OS variants. Additionally, the ROM also includes performance and stability improvements over the stock Android firmware offered by OEMs such as Samsung. Some of the main features included with this ROM are screen recording, ad blocker, notification FC disabler, LCD changer (persistent), Gesture Anywhere, recent panel settings, omniswitch, app circle bar, network traffic on statusbar, CPU info, boot animation changer, CM Theme Engine, Slim launcher, Slim Heads Up, QS screenshot tile, QS screenrecord tile, QS quick and smart pull down, QS Wi-Fi detailed tile view, and QS Location tile with advanced settings. The ROM is largely stable and can be considered good enough to be a daily driver ROM. There are a few minor issues but they can be fixed easily with a few workarounds.

In this tutorial we are going to walk you through all the steps that are involved in flashing this Unofficial Android Ice Cold Project Custom ROM on your Samsung Galaxy Note 4. You will need to make sure that you follow this guide carefully and perform each step that is mentioned in the guide correctly. If you skip a step or use your own judgment to do anything differently in any step, you may end up bricking your Samsung Galaxy Note 4.

Before we get to the actual installation process, we are going to discuss all the pre-requisites that need to be taken care of before you will be able to install this custom ROM on your device. The very first thing that you should do is to take a backup of all your important data as well as apps.

This is a very important step and you should always have a backup ready whenever you install a new ROM on your Android smartphone or tablet. To take a backup of your data, you can install any of the popular backup and restore apps from the Google Play Store like Titanium Backup, Helium or MyBackup. You can also perform a backup on your computer by using the Samsung KIES PC software. Apart from backing up your personal data and apps, you will also need to take a Nandroid backup of your current ROM so you can revert to your current ROM in case you are not happy with this Android 5.1 Lollipop custom ROM.

it is very important to make sure that you have at least 60% battery charge remaining on your device. Performing a ROM installation when you have low battery remaining can be risky as your smartphone will get bricked in case the battery runs out before the installation process is completed. So if the battery on your Galaxy Note 4 does not have around 60% or higher charge remaining, plug your device to the charger and let it charge before you proceed to installing the ROM on it.

make sure that the USB Debugging option under Developer Options has been checked. You can check this by going to Settings – Developer Options – USB Debugging.

Update Samsung Galaxy Note 4 SM-N910F/G to Android 5.1 Lollipop

The first thing that you will need to do is download the AICP Unofficial 9.0 V2 ROM ZIP file to your computer from this link. Along with the ROM ZIP file, you will also need to download the GAPPS (Google Apps) package for Android 5.1 to your computer as the ROM does not come with any Google apps or services by default, just like any other AOKP/AOSP based ROM. You will find the GAPPS ZIP file at this link. Additionally, you will also need to download the ZIP file from this link to fix music and video freeze bug that exists with this ROM.

Once all the three files have been downloaded to your computer, connect your Samsung Galaxy Note 4 to the computer using the USB cable. Now transfer the three files to the internal storage of your Galaxy Note 4. You should make sure that you transfer the files to the internal storage only and not the external SD card. You will not be able to flash these files from recovery if they end up on the external storage.
After all the three files have been transferred to the internal storage, unplug your Samsung Galaxy Note 4 from the computer. Now turn it off and boot into recovery mode.

In recovery, tap on the ‘wipe data factory reset’ option to perform a factory reset. Once the factory reset is complete, tap on the ‘advanced options’ to individually wipe cache, dalvik cache, data and system partitions. This is a very important step and should be followed each time you flash a new custom ROM to your device. In future if you are upgrading to a newer version of the ROM, you will only need to wipe the cache and dalvik cache.

Now return to the main recovery menu and tap on the ‘Install zip from SD card’ option and then ‘choose zip from SD card’ to choose the ROM ZIP file that you transferred to the internal storage. Wait for the flashing to be completed.
Once the ROM ZIP package has been successfully flashed, proceed to flashing the GAPPS package in the same way.

After the GAPPS file has been flashed, flash the fix ZIP file as well.
Now tap on ‘reboot system now’ option.

You should now have the Android 5.1 Lollipop Unofficial AICP custom ROM installed on your Samsung Galaxy Note 4. The first boot is likely to take slightly longer than usual, so do not worry if your device takes a few minutes to boot to the homescreen.
