[MOD][FIX] Grorkmod (STABLE|SYSTEMLESS|LOS-Version)

[vsrookie]

Hello.

After many many tinkering and a small hint from @rovo89, finally i can present you the first stable version of the grorkmod.
Added v1.7 LineageOS-Version

Fix for bluetooth
Updated Audio_policy.conf will be copied. Result is a working audio.

Added v1.0 LineageOS-Version

Until the fix is integrated in the Rom, you can use the LOS-Version for a working fm-radio.

The Fix will add the following rights to selinux:
system_app fm_device:chr_file {write, read, open, ioctl}
This is a quick'n'dirty way.

Added v1.1 lite

In this version the fix is the same, but the script dont need an installed superuser. Also it will leave the system untouched.
Ive tested this version with Eragon v4.0 (With Gravitybox as testmodule, guess what... its working. Ive NOT tested if magisks will work properly with banking apps. please do it for me.

Review betaversions

In the past versions i have tried to workaround the problem.
At projectstart i have seen many audit denies. I tried to eliminate them with injecting allows to the sepolicy.
This was a part of the little success i had with the first versions. The other part was to set the classes internally to permissive.
These two components and the "bootprocesshack", in which i changed the sepolicy-binary in root, made the beta versions working.
The problem in the beta version was always, that in some cases the workaround didn't worked.

Stable

After an hint that @rovo89 gave me, i saw the problem in seconds, and.... *FACEPALM*
I've saw the problem and didn't saw it anyway.....
For a reason i don't know (maybe it's just a fault from Elephone or mediathek?) they "forget" to setup the contexts files not correctly.
With this mod i fix the entries in the seapp_contexts and file_contexts.
This is the whole magic.

Installation

1. • Wipe Dalvik/Cache
   • Install ROM
   • Install SuperSU
   • Install grorkmod
   • Install xposed
   • then boot to system

Have fun with a fully working ROM!

About

This is a solution to get the xposed framework running in enforcing mode AND keep it running after a reboot, dalvik cache wipe and installation of any app.
The main goal is for sure the working xposed framework in enforcing mode, but as we all noticed there are several issues that come with a script that only set the selinuxmode to permissive. That's the second part of this project, trying to not change the behaviour of apps like on stockrom.

Background

As i get the p9000 and installed eragon the first time, i installed the xposed framework as fast as i can and.... everything works? Installed modules and... nothing worked!? I tried some things to get it working, but with everything i tried, i had to take a smear.
Pretty annoying, isn't it?
I took a deeper look into selinux and tinkered.... and tinkered ... and tinkered!
Now i think it's time to share my stuff with this great community and i hope that i will help with my mod.

BEWARE/Disclaimer

If you don't know what selinux is, then i think you have to read a "little bit" about it. (pure linux stuff; non Android)
If you google it, then you find everything you need, to learn more about it. If you don't know what rooting is, then play Angrybirds instead.

Understand this:
SELinux is a abbreviation for Security Enhanced Linux. That isn't just a name, it's the programm.
With this mod you will loose the S in the name.

Please be sure you have made a backup from everything that's important for you.
I've done this mod in all conscience, but I'm not responsable for bricked devices. Realize it!

You have been warned! :good:

The idea behind

This mod installs setools binaries to /su/bin, so you use them on terminal with this mod. We need them to inject permissions to the sepolicy binary. The next problem is, that the original sepolicy is compiled into the kernel (rootfs). Thats why it will be overwritten on boot. If you inject permissions manually, they are gone with every reboot. So i wrote a script that injects permissions on boot to a patched (with superkernel) sepolicy binary and copy it to root.

Installing

Now the funny part! :highfive:

What you need
I tested this mod on Eragon v2.8 and Aerom V3.
So you need one of these Roms (i think it will also work on rooted stockrom and Darksense, cause the two three other based on stockrom)
superSu 2.74
xposed framework v85
and of course my mod (see the attachement).

How to
Download everything to your SDCard.
Make sure you have wiped your device, so you can start fresh. (I don't have tried, only to flash this mod.)
Dont reboot. If you reboot, then reboot into recovery again!

Install the rom of your choice. (If you install Eragon v2.8, then be sure to delete the script inside /system/etc/init.d)
Install SuperSu 2.74
Install XposedFramework v85
Install Grorkmod

After this step just reboot. And check if everything is fine.

If not then let me know!

Hi.

Thank you. Didn't noticed!

I've added "the idea behind" to the first post.

do you need the xposed app?

 

[vsrookie]

Hi.

What do you mean?

You have to install it for installing xposed modules. Just install it after boot.

ok, thanks. did a quick test with AeromV3. At first gravitybox, app settings, flat color keyboard* worked after a soft reboot. Ebay app also worked.

Then on next soft reboot there was 2 loops of optimizing apps and only gravity worked.
Shut off the phone and restarted, none worked. After what I have read that was expected.

Did a soft reboot in xposed,then loops of android is starting- optimizing app . after third loop i shutdown the phone and restarted. Then xposed did not work. Tried another soft reboot, this time no loop and xposed modules are working and ebay app works.

Hi.

Never tried to softreboot the phone. I will try and report back as fast as i can.
Did you made a clean install? Or dirty flashed the mod?

[mangoman]

clean AeromV3 install. normal reboots do not work

Good I have 3 sim cards on same number the way I mess with my phones.

 

[vsrookie]

Hi.

Tried to softreboot the phone from xposed installer. That don't work, that's sure.

On Eragon normal reboots work. I will test with Aerom soon.

ok, will test eragon. It stopped working altogether now on AeromV3 after several soft reboots, shutdowns and normal reboots.
gravitybox seemed to work, but other modules seemed to stop. Disabled gravity but that did not seem to work.

Also the android starting, optimizing app message loops seems random.

Seems better on eragon. Works after normal reboot, and from powered off. Ebay also works.

edit2..
so after installing same apps and some reboots, xposed modules will not function sometimes. A few reboots and this time they came back working.

one app that does not work is amplify, maybe just coincidence but that one seems to brake the other when selected.

Is your edit 2 referring to eragon 2.8?

 

[mangoman]

yes.
3-4 reboots, and not working. 1 soft reboot and they came back.

so seems a luck of the draw when it works after a reboot.

 

[arlrb]

Thanks, I'll leave it for now.
I made a backup of my eragon before I did any xsposed stuff, I can install that for eBay etc ...

PS - so I can't install this with xposed already running?

 

[vsrookie]

yes.

That s not true.... sorry.

I am on aeromv3 right now rebooted around 5 times (normal, not over xposedinstaller).

Everything works as expected. Even with amplify.

Do you use backuped Apps?

Hi.

You have to do a clean install of the Rom of your choice. Install newest supersu and xposed, install this mod.

Everything should work fine.

If it is not so, there is another Problem. Maybe backuped Apps?

PS: if you install Eragon, don't forget ti delete the initd Script.

[mangoman]

yes, strange. At first on eragon it worked with reboots, but after a few of them not so much. Then soft reboots seemed to do the trick.

Right now got amplify working. This time did not enable it in xposed first, but rather ran the app then enabled it in xposed when it asked.

They say you should flash the framework before installing the installer & modules.
So should I install this after framework but before installer, or after framework & installer?

Hi.

Can you give the new version 0.7 a shot?

I had issues if the phone shut down completely. At this point i had also no running xposed anymore.
Fixed this.

Now i can reboot also out of xposed installer.
