Create multiple profiles for ISLAND app

create_multiple_profiles.md

Setup multiple island spaces

Note: Must have an work profile already setup, So that we can modify fw.sys.max_profiles to allow more work profiles

su # to gain root access
resetprop ro.debuggable 1 
am restart

Modify fw.sys.max_profiles prop

setprop fw.sys.max_profiles 10

Create new work profile

# this is the user id of the initial island which was setup from the application
exid="10"
id="$(pm create-user --profileOf 0 --managed Island | grep -Eo '[0-9]+')"
echo "ID: ${id}"

Open /data/system/users/11.xml and add following code below <name> Island </name> but above <user>

where 11 is the user id of newly created work profile

<restrictions no_wallpaper="true" />
<device_policy_local_restrictions>
    <restrictions_user user_id="10">
        <restrictions allow_parent_profile_app_linking="true" />
    </restrictions_user>
</device_policy_local_restrictions>

It should look like this

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<user id="10" serialNumber="28" flags="4144" type="android.os.usertype.profile.MANAGED" created="1652171823625" lastLoggedIn="1652351262370" lastLoggedInFingerprint="Sat Apr 23 21:25:20 IST 2022" profileGroupId="0" profileBadge="0">
    <name> Island </name>
    <restrictions no_wallpaper="true" />
    <device_policy_local_restrictions>
        <restrictions_user user_id="10">
            <restrictions allow_parent_profile_app_linking="true" />
        </restrictions_user>
    </device_policy_local_restrictions>
    <lastRequestQuietModeEnabledCall>1652340558380</lastRequestQuietModeEnabledCall>
</user>

Execute these commands

cd "/data/system/users/${exid:?}" || exit 1
cp app_idle_stats.xml appwidgets.xml \
   device_policies.xml \
   package-restrictions.xml profile_owner.xml \
   settings_secure.xml settings_ssaid.xml settings_system.xml \
   "/data/system/users/${id:?}/"

@danielsanaw almost any ROM will work (tho of course some weirder more exotic ones may make things harder)

Basically if both Magisk and the ancient magiskhide propsconfig module work chances are high this trick will work

hey linda could you help me out here please, i keep getting this error.

"No Busybox found"

i've flashed "built-in busybox" magisk module + copied the binary file into root/data/adb/modules/busybox. directroy.

still when i run "props" command in terminal su , it kept saying "busybox" not installed.

im using apatch root.

+i kept getting "system read-only" when try to install busybox via busybox-installer.

modules in apatch= magisk's builtin busybox, magical overlaysfs, magiskhide props config, nsg sepolicy for A11, zygisk next, lsposed.

please help me out here, guys. Thanks in advanced.

@danielsanaw
I don't have any experience with apatch root, but magisk has its own busybox which if memory serves lives at /data/adb/magisk/busybox

Apparently the propsconfig module expects it to be present which I presume is not the case with apatch root

Do bear in mind that module appears heavily dependent on other magisk instrumentation, such as resetprop tool and Magisk's early boot script semantics.

I don't know how closely can apatch root emulate the necessary environment.

However, if you have Zygisk and Lsposed you can try this tool which does what my lifehack does but via lsposed hooking

(In fact my hack was born from carefully looking at what alwayscreateuser does and finding a way to recreate it without Zygisk, because getting Zygisk on Graphene is a massive boondongle I am too lazy to mess with)
