[fix] WIFI for JVU (useable on previous release to) 100% tested

I will be releasing the fix on my rom sometimes next week , and I will not compile this for every set up / theme / rom out there but if you know what you are doing this is pretty easy fix
Here is how the fix works :
Our present kernel source is 2.3.4 and we are running 2.3.6 base . So I looked at what was different in the wifi files from 2.3.4 to 2.3.6 and there you go .
Files attached at the end of the post are 2.3.4 JVQ (already modified for JVU)
(fyi these files come from apk manager just rename your jar files to apk to decompile them then copy the files attached at the end of the post in there respective places )
_framework.jar :
delete: \android\net\wifi\WifiStateTracker$1.smali
and copy paste the files attached and recompile
_services.jar :
copy paste the files attached and recompile
_'etc' folder copy paste into your /system folder in your rom/Phone
(not 100% sure its needed but better use them anyways)
IF you are not on JVU you need to change the ids manually , the names of the values are written in the smali so that will make it easier to port to other versions .
Tested on Belkin router (the worst of them all) and on public wifi with no dhcp assigned . after an hour no disconnect flawless victory
For beginers here is a guide by pantrif13 : http://forum.xda-developers.com/showpost.php?p=22032781&postcount=16
Credits to Shoman94 for pointing me in the right direction and providing files to help me diff(and being insistent about it )
suprstar for testing
and gtg465x who achieved this first on the SGS2

Will this fix the adhoc problem too ?

Pleasure.. Spam my thx button ?
Little mention on your credits maybe
To others if you don't know how to use apkmanager this mid is not for you
Tell your favorite rom dev about it it takes a few minutes to apply this
I could have kept this to my rom but I put it out there for all rom to use
This fix really works

As said in OP, until built for any ROM version: Be your own developer!
Adb pull the system .jar files, decompile with dependency, edit, compile, rename, adb push result.

are a beginner and I did not understand anything ,more clear PLEASE if you can, thanks!...I think your work is useful

I think many people could do with a step by step guide for this if anyone has the time to do it

Please note our desires about this topic...declared above..thanks!

I think that dagr8 explain very clear what needs to be done (but you need to have some experience with decompiling and compiling).
Here what you need to do in case you are on jvu:
1) First off all you need the latest JDK and JRE installed on your system.
2) Then go here to learn how to set up apktool.
3) After the setup of apktool pull the services.jar (services.odex if you have odex rom) and framework.jar (framework.odex in case of odex rom) and put it in your apktool folder
4)
a. If you are on deodex rom you only need to run these commands from the folder of apktool (go to apktool folder and press ctrl and shift -open command window here)
Code:
apktool d framework.jar
apktool d services.jar
You will find two new folders (servicesout and frameworkout)
Then do what dagr8 said in op.
b. if you are on odex rom: get the latest baksmali from here
then pull all your system/framework to your pc and put baksmali.jar there.
Open commant window and write:
for sevices:
Code:
java -jar baksmali.jar -c :core.jar:bouncycastle.jar:ext.jar:framework.jar:android.policy.jar:services.jar:core-junit.jar -xa 10 services.odex -o services.jar.out
for framework:
Code:
java -jar baksmali.jar -c :core.jar:bouncycastle.jar:ext.jar:framework.jar:android.policy.jar:services.jar:core-junit.jar -xa 10 framework.odex -o framework.jar.out
Then do what dagr8 said.
5)Both deodex odex: get the latest smali from here
Put it in the folder with out folders and write:
for services:
Code:
java -jar smali.jar sevices.jar.out -o classes.dex
you will find a new classes.dex file.Open services.jar with winrar and drag and drop (overwrite) there.
Then for framework:
Code:
java -jar smali.jar framework.jar.out -o classes.dex
Same here (open the jar with winrar and drag and drop)
5) if you are on deodex rom you finished just push the new services and framework to the system along with the files which provide dagr8 for etc folder.
6) if you are on odex...go here and follow the guide from the part odexing back...
I hope i helped!
Thanks a lot dagr8 for this!!

can dev provide the public.xml that this was made with for comparison of ids?

Thanks for your time and explanations given pantrif13 and dagr8, expecting something more simple ... you can install the CWM (example) ... so (who knows it's easy anyway)...expect other solutions!!!to solve the problem with wifi...

Great job. Thanks

i m on jw1 deodex jetpack custom rom 8.2 and i am using the jvt modem...
will you provide fix for jw1 rom next days? thank you !!!

Hey, if you upload the android.policy.jar (found in /system/framework) from the XXLEF ROM I can do this for you. If it's not deodexed I'll also need the android.policy.odex.
Alternatively you could DIY using the instructions on this thread: http://forum.xda-developers.com/showthread.php?t=1585309

Thanks Atarii!!:good:
but i have a problems on it,
I've extracted out a files from android.policy.odex and edit the KeyguardViewMediator.smali successfully, but how to compress it to a android.policy.odex............? Can you teach me?

Hey,
Good work getting the file editted. :good:
After you made the changes to the smali code, you need to compile it into a classes.dex file:
Code:
java -Xmx1024m -jar smali.jar out -o classes.dex
(Where out is the name of the folder with the smali code in)
Now drag that classes.dex file into the original android.policy.jar (keep a backup of the android.policy.jar somewhere else).
Then follow the steps from "ODEXING BACK" in this guide: http://forum.xda-developers.com/showthread.php?t=1208320 :fingers-crossed:
Let us know if you have any troubles

[Q] Decompiling android.policy.jar not working

Whenever I decompile my android.policy.jar with apktool all I get is a folder called android.policy.jar.out with the file apktool.yml in it. Whenever I decompile any other jar or apk it decompiles all the xmls and resources just fine. I got my android.policy.jar from the /system/framework/ directory. The jar was only 303 bytes so maybe I am missing the files or something. Anyone have any clue why this is happening?
If it helps, I did the if framework-res.apk command and it mounted it just fine and I can decompile other jars and apks just fine. I am on sgs-i747 4.1.2 TW stock.
Thanks

Can I just use apktool to decompile it like "apktool d classes.dex classes" in the command prompt?
After I make modifications how would I pack it back into a jar? Would I recompile the classes folder and then insert this into the original jar or what? Thank you for the help

After its recompiled open the android.policy with 7zip and add the new classes.dex to it, it will overwrite the old one

I have checked the archive in the android.policy.jar with 7zip and the only thing in it was a folder named META-INF filled with a MANIFEST.ML file no classes.dex
EDIT: this may help, but all my jar files in the /system/framework folder are 313bytes exactly. Is this normal or a sign of something wrong

The problem with that is I just reflashed rooted stock rom with odin and the jars are all empty (just the meta-inf with the manifest.ml file in them). What is going on here?

Hi,
In order to make changes in the android policy.jar file, you first need to deodex it. You can very easily deodex it using my software over here - http://forum.xda-developers.com/showthread.php?t=2213235
Then, follow this huide to decompile the jar - http://forum.xda-developers.com/showthread.php?t=1732635

You do not need to deodex your entire rom. Only deodexing the android policy.jar file will suffice. Decompiling a jar file is slightly different from decompiling an apk. We do not use apktool to decompile jar files but execute these two commands - (First extract classes.dex from anroid policy.jar using winrar and place it in the same folder as smali.jar and baksmali.jar)
Code:
java -jar baksmali.jar -o classout/ classes.dex
Make any changes that you want to do now.
Code:
java -Xmx512M -jar smali.jar classout/ -o new-classes.dex
Then rename new-classes.dex to classes.dex and put it back into the jar file.

Is there a guide how to return to odex? My rom is odex. I now have my mod android.policy.jar

AFAIK, when you deodex a framework file, all the rest needs to be deodexed also, something that doesn't exist with apps files...

I am sorry, I confused framework files with apks coz I have myself tried using a deodexed apk on a fully odexed rom and it worked. You are right, using a partially deodexed framework causes bootloops.

SystemUI deodexing (Solved)

Hey so I have noticed that Charles_l has made a Pixel home button animation for the Nexus 5X (found here : http://forum.xda-developers.com/nexus-5x/themes-apps/mod-pixel-navigation-bar-home-button-t3498614) and wanted to reverse engineer his work so I can port it to other devices. An important thing that I noticed was that he deodexed the SystemUI.odex file and build it back into the SystemUI.apk so he can add files found in the Pixel's odex files.
Now my first step to reverse engineer was to figure out how to deodex the odex files and build them into the apk. At the moment I have downloaded the baksmali.jar and smali.jar from JesusFreke ( https://bitbucket.org/JesusFreke/smali/downloads ) and shifted them to a folder to work in. I have extracted the odex files from the Nexus 5X
Code:
adb pull /system/priv-app/SystemUI.apk/oat/arm64/SystemUI.odex
and extracted the framework for baksmali to work with
Code:
adb pull /system/framework/arm64/
I then moved all the files to the folder containing the baksmali.jar file and ran the command to extra all the smali files
Code:
java -jar baksmali.jar x -c boot.oat SystemUI.odex -o SystemUI
Now I was wondering, How do you build them into the apk? I have tried a few things but they just cause the SystemUI to crash once booted.
If anyone can tell me how to fix this, then please tell me.

I figured out how to do this so it doesn't matter anymore.
If anyone wants to know you just need to make a small folder in the apk and don't the files to it.
