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.
