If the script in boot is what is enabling app installation, couldn’t you just use a standard rooted boot image after all apps are installed? Wouldn’t that disable installation but keep root?
that too 
Definitely easier than editing services.jar
Though I was using this yesterday, pretty great:
Thank you for responding.
I like what @ars18 wrote downthread though.
Should work, report back.
Just tried it. Worked great!
Thanks
Great
@ars18 posted somewhere how to block WiFi
Change the line in the build.prop

Is there any way to have filtered Spotify and filtered WhatsApp on a qin f21
Are you looking for a modded APK or you are gonna use hosts files…?
what ever works I don’t really know these things
Not that I can help you with either option, I just wanted your question to be a bit clearer for those reading.
The short answer if you say “I don’t really know these things” is, No it’s not simple to accomplish what you want.
will if there’s apk file I’ll do it that way or if you know anyone that does it or sells it
What do you mean by filtered spotify? No pics?
Yes and videos of you know any filters for qin
Are you looking for info on how to do it yourself, or for someone to do it for you?
someone to do it for me I want to buy a filtered phone for myself
There was a thread somewhere about a new kosher phone, came in a flip and bar version, the flip version looked like a Cat S22 with upgraded specs.
Anyone know what I’m talking about?
Where is it?
Found it.
