Android Install Guide

This method requires your Android device to have at least 25GB of space free. You do NOT need to be rooted, this method should work on all devices. If you have less than 25GB of space free (but enough to fit the game), please use the low space tutorial instead. This method was discovered by Hero and refined by FeatherSnek and I. Some of the text on this page is taken from a guide written by FeatherSnek. If you need assistance, please feel free to e-mail me at niellis@caramail.com

Pre-requisites

• Uninstall any existing Rays app. Note that this process will delete any existing save files! There is no preventing this. However, if your device is rooted or happens to be an emulator, you may be able to recover your save file.
• The game needs ~11GB of space once installed.
• While it is possible to install the game onto Bluestacks, this guide does not support it, and at this time I am not interested in writing a guide to support it.

Guide

Windows users: If you are installing from Windows to an Android device or an emulator, this link will provide an easy installer, created by Nexogone, that does the entire process for you, including downloading the game files. To use it, download the file to your computer, unzip the archive, and run the .bat file.

If you're using MacOS or Linux, please read on.

1. Download this modified version of the Rays APK and install it to the device or emulator you wish to install Rays to.
   • You will be asked to allow installation from this source. Allow it
   • Do not open Rays (if you do by accident it's not the end of the world. Make sure you fully swipe close it though)
2. On your computer, download the Rays complete install and unzip it on your computer somewhere easy to find.
3. Install ADB (Android Debug Tools):
   • If you have a package manager: If you use a package manager such as homebrew, macports, winget, chocolatey, pacman, apt, or similar, it will make your life slightly easier to install it from said package manager if it available. ADB will likely be listed as either "android-tools", "adb" or "android-tools-adb". If you aren't on Linux and don't know what a package manager is, you can ignore this and follow the link below to download ADB for your operating system.
   • Otherwise: Android Debug Bridge can be downloaded for all three platforms here. The link you want will be labeled "Download SDK Platform-tools for [your operating system]".
4. If you downloaded ADB in a zip file rather than installing it, unzip it on your computer. Locate the "files" folder inside the complete install you downloaded in step 2 and move it inside of the folder containing ADB. This folder should contain multiple files and will likely be called "platform-tools".
5. Enable developer mode on the Android device or emulator:
   • Physical device, such as a phone or tablet:
     1. Open the settings app
     2. Go to "About phone"
     3. Go to "Software information"
     4. Tap "Build number" until developer mode turns on
     5. Return to settings
     6. Go to "Developer options"
     7. Turn on "USB Debugging"
     8. Do not do anything else, back out and close your settings app to encure you do not change any other settings
   • Emulator: This varies widely from emulator to emulator, unfortunately, but it will be somewhere in settings labelled something like "developer mode" or "debug bridge".
6. If you are using a physical device, connect it to your computer. Ensure the cable you use is capable of transferring files and that you have selected "file transfer". If a prompt shows up asking you if you trust your computer, hit yes. Emulators just need to be opened and started.
7. Open a command prompt/terminal window in the folder containing the "files" folder:
   • Windows: Open the folder, type cmd in the navigation bar of your file explorer, and hit enter. This will open the command prompt in your current location
   • MacOS: Locate the correct folder and right click it. Select "New Terminal at Folder".
   • Linux: This will vary heavily, but you can usually open the correct folder and then right click the background of your file browser and select "open terminal here". If this option is not available, place the folder in your user directory (it should be named the same thing you login as) and rename it something easy to type. Then, open a terminal emulator (it should be named something like "konsole" or "gnome-console" or "xfceterm") and type cd [whatever you renamed the folder to]
8. All further instructions take place on your computer in the terminal/command prompt opened in the previous step. You will be copying anything formatted like this into this window. The exact formatting is important, including spaces and punctuation. Depending on your operating system, pasting into the terminal may require you to use ctrl+shift+v rather than simply ctrl+v.
9. adb push ./files /data/local/tmp/
   • A prompt may show up on your phone asking if you want to allow usb debugging access. Allow access
10. adb shell
11. run-as com.bandainamcoent.torays
12. cp -r /data/local/tmp/files .; echo Finished; date
    • This may take several minutes depending on your device. Please be patient. When the process finishes, it will tell you inside the window and print the current time and date.
13. exit
14. cd /data/local/tmp
15. rm -rf files
16. Rays should now be installed! Close the terminal/command prompt window, properly disconnect your phone, and try opening the game. If it works, please do go back and disable debug mode in the settings. If it doesn't work, feel free to get in touch and ask for help at niellie@caramail.com .
