Prepare or rename the iGO_Arimi folder, fill it with everything you need, and enter the following in sys.txt:
[folders]
data_folder_name="iGO_Arimi"
Run the installation of iGO_Arimi_9.18.27.955559_VRSD.apk. Due to the additional security in A14, devices with an unlock code will need to enter it. It will complain about the version being outdated, etc. Ignore it, select "Install Anyway" and agree (Yes). Next, the installation should ask for permissions. Grant all permissions, of course. If not, don't launch. Long-tap the new icon, select "Information", "Permissions", grant all permissions, launch the program, go through the initial settings, exit. You can replace the new save file with a save file from an older version...
