Cool

Warning

The new services.jar seems to have a bug that blocks adb install.

Installing apk’s on the phone itself works.

Performing Streamed Install adb.exe: failed to install C:\Users\jhjhjhj\Downloads\in.krosbits.musicolet_6.6_build400-40000_minAPI16(arm64-v8a)(nodpi)_apkmirror.com.apk: Error: adb install not allowed 1!!

@KosherFlipper said he will patch later, then I will update.

Not sure what you are trying to say

148

Hopefully someone else will try. Anyways, it’s getting patched.

“They originally added code that only userdebug devices can install (userdebug is what’s usually used during testing vs regular user builds).”

Tried the powershell route? Whaddya think?

149

whos they

150

I’m assuming qin

On the stock builds, this is the error you get. Dunno why changing what he changed did that though.

I must’ve missed something.

151

not sure - works for me though

152

Didn’t you remove adb from /system/bin?

153

Nope

154

Temporary fix:

Change this in the build.prop and adb install will work.

  • ro.build.type=userdebug
  • ro.debuggable=1
  • ro.secure=1

I can just add this to the exe permanently, but I’d rather take a look at services.jar, for the meantime.

I’ll probably add it temporarily

Update

Added it to the powershell and exe install method. ADB install works. Will work on actually fixing services.jar a different time.

Run the command or download the zip with the exe and you’re good.

Update 2

Man, this really a rollercoaster. I’ve confirmed a bug with the new services.jar…

Volume shortcuts do not work anymore… Time for me to take a break for a while.

Pretty sure I fixed all issues. Will upload soon when I’m sure and then turn the instructions into a full guide.

  • ADB install working without any hacks
  • Volume shortcuts exactly the same as before
  • Apps not getting killed

The issue was that the services.jar that was patched had allot more than just the apps not getting killed part.

Update

All updated, the irm command and zip download should be all good.

Still waiting on confirmation that I did is alright, then I’ll make a full normal post.

Whoops. Will remove now and decompile 1.1.1 later too be sure.
