Getting AllShare Cast working on modified devices

[TheCyber]

Well, i've hacked libWFD_ENGINE.so some time ago for my own needs. The way i've able to make it work only by disabling HDCP. So, this hacked version uses clear data without HDCP to talk with AllShareCast dongle.
I don't know if generic miracast dongles will accept data without HDCP as i don't have such device.

Included version for I9500 works with I9500XWUBMG1, I9500XXUBMG9, I9500UBUBMH1. Probably, it's compatible with other firmware versions.

P.S.: Since it's developers forum, you should know how to replace the file.
P.P.S: You can use this patched version in any ROM you want, but please give a credit to me.

My tv use Miracast and my S4 not work with this patch... please help me

Hi,

I had made the patch for Note8 successfully but with the recent update to the S3 (4.3) , my S3 had the same issue.

Unfortunately I can't find the pattern for the 3rd patch in the lib file.
Can anyone help with this ?

I need a solution on my Note 2.

I found a patched one, and it works like a charm on my rom N7100.XXUEMI6
I'm happy to share it

Please I need a similar solution on my Note 2.

I'd appreciate if you could help me.

attached is the file from my Note2

If I can get the instructions (or patched lib for S4) from Sorg, I will do it both for S3 and Note2 (Android 4.3)
I promise

Is it flashable and does It works on GTN 7100?
Edit: im sorry. What i meant to ask was if it works on GT-N7100 stock 4.1. But i already tried and it does not.

@MohammadAG , you've done a great job by updating the first post. Thanks.
I believe we should refer to this thread from device specific threads because there are many users who are using modified roms and have no solution for Allshare Cast dongle issues...

 

[monkeydrufy]

Sorry guys to disturb you

any hope to see the all share cast work on I9505?

thanks

 

[daciangeorge]

I've thought Cydia Substrate gives something special, but after quick look i've found it providing not more than XPosed already provides. You cannot make patch for this using Cydia Substrate because the only thing you can do by this is to hook JNI functions called from Dalvik code (you can do the same in Xposed). You cannot hook internal lib functions where the "magic" happens.
The only way is to replace the whole lib i've provided so far.

thats pretty obvious no offence to anyone who thought different,if you read the cydia substrate is basically xposed in a different form, if you read up on xposed it modifies app_processes file file to allow you to modify code through the dalvik(thats how i added xposed with preinstalled modules in one of my roms), cydia substrate works somewhat the same as i understand? but patching C++ in no easy task at all im not sure if we will ever be able to do that without actually touching the actual file itself..

Hi, I am wondering what it would take to extend this to other devices and maybe even make an app. I have a tesco HUDL which I bought as a present for someone for xmas, they have a brand new samaung TV, it would be great to get this working. After enabling screen mirroring on the HUDL it tried to connected and exhibited identical problems as my S3 did before this fix, it connected then dropped reporting a hardware problem. This suggests to me this fix could work for any device with wifi direct screen mirroring.

What is required to write a fix for the HUDL, what changes need to be made to the S3 fix?

 

[studentjunk]

I don't know about the hudl. This method circumvents the security checks the app uses. So it needs to initially work on the unrooted device. Decompiling the lib files and searching for the modifications mentioned might be enough to extend to other Samsung devices. All of the details are above my head. Otherwise I would have tackled it already.

Hi all,

Im having a similar issue with allshare cast myself and was wandering if anyone can help.

Firstly when i select the screen mirroring quick toggle my settings immediately FC. I can however access the screen mirroring options direct from the settings menu, i am able to connect to the dongle for about 3-4 seconds then it disconnects itself.

Im running 4.3 rooted but on stock kernel, the logcat for the toggle error is below:

D/STATUSBAR-AllShareCastQuickSettingButton( 2781): onClick() - state : true
D/STATUSBAR-AllShareCastQuickSettingButton( 2781): WFD activate
E/AndroidRuntime(15827): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.android.settings/com.android.settings.wfd.WfdPickerDialog}: android.content.res.Resources$NotFoundException: File res/raw/allshare_confirm.ogg from drawable resource ID #0x7f080000
E/AndroidRuntime(15827): Caused by: android.content.res.Resources$NotFoundException: File res/raw/allshare_confirm.ogg from drawable resource ID #0x7f080000

I would really appreciate it if anyone can help me out.

Thanks

Mike

Hi,

I keep receiving PMs saying "how did you do it?" about the patch.
First of all, I am not the developer who made this patch. I am just copying modifications made by him.

Here is a short description of steps to follow if you want to do the same for other devices:

1. download and install IDA Pro
2. download and install WinHEx
3. download and install any text compare util
4. Open patched and unpatched version lib file of the same device (any device) with IDA
5. get text output of both files to the text compare utility
6. find the 3 differences. analyze where they are in the file (look for seacrhable text patterns)
7. open YOUR device's unpacthed lib file with IDA pro
8. find the correspondances found on step 6 in your own file.
9. note the line number (hex address) of each 3 correspondances
10. now open all 3 files on Winhex
11. jump to the noted hex addresses and change the bytes according to the difference of 2 files of the same device.
12. make the change on your own file and save.

I hope it helps some of you..
