Box for Root

BOX

Transparent Proxy for Android (Root)

Introduction

Box for Root (BFR) is a Magisk, KernelSU, and APatch module for running transparent proxies on rooted Android devices. It supports Clash/Mihomo, sing-box, v2fly, xray, and hysteria.

Features

• Multiple proxy cores and network modes, with configurable app and process filtering.
• Automatic service start after boot and service control from the manager or command line.
• Optional network-state controls, scheduled updates, and cgroup resource limits.

Installation

Download a release ZIP and install it from the Magisk, KernelSU, or APatch manager. Recovery installation is not supported. KernelSU versions below version code 10670 are not supported.

The installer offers interactive options for download acceleration and proxy-core binaries. Connect to the internet if you want it to download binaries during installation. Reboot after installation. Existing data under /data/adb/box is backed up and restored during an update; the installer also offers to restore supported settings from the previous settings.ini.

Apk Manager

You can use the BFR Manager app (optional) to manage Box for Root on your device. Download BFR Manager

⚠️ If you receive continuous notifications, open Magisk Manager, navigate to SuperUser, search for BoxForRoot, and disable logs and notifications.

Files and Configuration

• Module files: /data/adb/modules/box_for_root
• Persistent data, scripts, and proxy-core configurations: /data/adb/box
• Main settings: /data/adb/box/settings.ini
• Runtime logs and state: /data/adb/box/run

The selected core is set by bin_name in settings.ini (clash, sing-box, xray, v2fly, or hysteria). Its executable is stored in /data/adb/box/bin; its configuration is in the matching directory under /data/adb/box (for example, /data/adb/box/clash/config.yaml). Edit configuration files only while BFR is stopped, and keep their proxy listener ports consistent with settings.ini.

Network modes

Set network_mode in settings.ini to one of the following:

Mode	Traffic handling
redirect	Redirect TCP; UDP is direct
tproxy	TProxy for TCP and UDP
mixed	Redirect TCP and route UDP through TUN
enhance	Redirect TCP and TProxy UDP
tun	Route TCP and UDP through an auto-routed TUN interface

Supported modes depend on the selected core. xray and v2fly require tproxy; hysteria supports redirect, tproxy, and enhance. clash and sing-box support the modes their configurations provide. tun mode is available for clash and sing-box.

App, process, and interface filters

• /data/adb/box/package.list.cfg controls app filtering. Choose mode:blacklist (the default) to proxy all apps except listed packages, or mode:whitelist to proxy only listed packages. Add one Android package name per line; a user ID can optionally prefix a package (for example, 0:com.example.app).
• /data/adb/box/gid.list.cfg contains numeric group IDs (GIDs) for process filtering. The mode in package.list.cfg also determines whether listed GIDs are excluded or included.
• /data/adb/box/ap.list.cfg controls network interfaces. allow <prefix> includes an interface and ignore <prefix> excludes one. The default allow-list includes ap+, wlan+, rndis+, swlan+, ncm+, and eth+.

When package or GID filters, or an ignore interface rule, are configured while Clash uses fake-IP mode, BFR switches to redir-host at startup for supported network modes.

Optional settings

IPv6 support, network-state service control, and cgroup resource limits are disabled by default. To enable them, edit settings.ini while BFR is stopped:

• Network-state service control: enable_network_service_control, use_module_on_wifi_disconnect, use_module_on_wifi, and the SSID matching options.
• Resource limits: cgroup_memcg / memcg_limit, cgroup_cpuset / allow_cpu, and cgroup_blkio / weight.
• IPv6 support: ipv6.
• Scheduled Geo and subscription updates: set run_crontab and the relevant update options to true, then set the interva_update schedule. Its default is 0 0,6,12,18 * * * (four times daily). The subs command documents subscription updates for clash only.

Manage Service Start/Stop

By default, BFR starts after boot. Enable or disable the module in the manager to start or stop its service. You can also use the installed /dev/sbfr command:

su -c /dev/sbfr start
su -c /dev/sbfr stop
su -c /dev/sbfr help

The equivalent direct commands are:

su -c /data/adb/box/scripts/box.service start && su -c /data/adb/box/scripts/box.iptables enable
su -c /data/adb/box/scripts/box.iptables disable && su -c /data/adb/box/scripts/box.service stop

To prevent automatic startup and manager-based service control, create /data/adb/box/manual. In manual mode, start and stop BFR using the commands above.

Maintenance commands

Run box.tool help to see all available commands:

su -c /data/adb/box/scripts/box.tool help

Commands include check, geosub, geox, subs, upkernel, upxui, upyq, upcurl, reload, webroot, memcg, cpuset, blkio, bond0, bond1, and all. The subs command documents subscription updates for clash only. Service commands are start, stop, restart, status, cron, and kcron; firewall commands are enable, disable, and renew.

Logs are stored in /data/adb/box/run. For more detailed configuration guidance, see the English guide, Indonesian guide, and Chinese guide.

Uninstall

Uninstall the module from the Magisk, KernelSU, or APatch manager. The uninstall script removes /data/adb/box and its service startup script. If data or service files remain, remove them manually:

su -c rm -rf /data/adb/box
su -c rm -rf /data/adb/service.d/box_service.sh
su -c rm -rf /data/adb/ksu/service.d/box_service.sh
su -c rm -rf /data/adb/modules/box_for_root
