I tried it with my smart device. As a result, I first need warp1.1.1.1 vpn, and the file after running von is an unsigned file, so I signed it with Lucky Patcher. (I don't think there's a need to change the sign to unsign in this part. I want you to upload it as a sign file as it should be.) After that, when you log in to the game, you'll see server error800, and after that, if you log in as a guest again, the game will run normally. After that, you can change your account and log in to Apple or Google. If I request Yunana24 again, I would appreciate it if you could also upload the sign file for non-root users.
