For a device which got so much sales on its release, it becomes compulsory for developers to regularly release Custom ROMs based on latest Android firmware for it. Similar situation with Galaxy Note 2, which was very popular phablet and now although it is old but that hasn’t stopped developers from releasing CyanideL Android 5.1 Lollipop custom ROM for AT&T Galaxy Note 2 I317.
If you happen to be AT&T subscriber with their own Galaxy Note 2 (I317) then I am sure you are reading this only because you want Lollipop on your phone. Don’t worry, we have posted a detailed step by step guide to help you install Android 5.1 Lollipop custom ROM on AT&T Galaxy Note I317.
- Make sure your AT&T Galaxy Note I317 is at least 64% or charged.
- Ensure that you have complete backup of all your important data.
- Make sure USB debugging is enabled on your smartphone. [If not, enable from Setting –> Developer Options]
- Download Galaxy Note 2 Drivers and install them on your computer.
How to Update AT&T Galaxy Note I317 to Android 5.1 Lollipop with CyanideL ROM
Step 1: Download the custom ROM and GAPPS. For easy browsing, place both the downloaded zip files on desktop of your Computer.
Step 2: Connect your AT&T Galaxy Note I317 to your computer to transfer the download zip files to your phone SD card. [Make sure latest Samsung drivers are installed, otherwise your PC won’t recognize your phone]
Step 3: Turn Off your phone and boot it to recovery mode. For that, press and hold “Volume Up + Volume Down + Power” buttons simultaneously until you see boot menu. [You can’t use touch in recovery mode, so use Volume Up and Down buttons for navigation and Power button for selection]
Step 4: In recovery mode, first tap on “wipe data factory reset” option to perform a factory reset. Once this is completed, go to advanced options and select “wipe the cache” followed by “dalvik cache” options to clear the cache.
Step 5: Go back to main recovery menu and select “Install zip from sd card” followed by “choose zip from SD card” and select the ROM zip file you have transferred to SD card in Step 1. Once ROM flashing is completed, repeat the same step for GAPPS.
Step 6: Repeat the above step for Google Apps (GAPPS) installation.
Step 7: Once the installation is completed, go back to main recovery menu by selecting “+++++Go Back+++++” option and reboot your phone by choosing “reboot system now” option from main menu. For the first time, your phone might take little more time than it usually takes, so don’t be panic as it is normal and will be only for 1st time.
