[MOD/ HOW TO] Enable WiFi Tethering

Nottach · Apr 30, 2013

THIS IS FOR THE BRAVE PEOPLE ONLY!!!

I deodexed my own system in order to do this modification.
I replaced the files manually using an on device file explorer.
I do not recommend doing this if you aren't comfortable dealing with smali.

I got tethering working by modifying:

TetheringProvision.apk

/com/sec/tetheringprovision/TetheringProvisionActivity$5.smali
--return -1 instead of 0

Code:

    .line 990
     iget-object v0, p0,  Lcom/sec/tetheringprovision/TetheringProvisionActivity$5;->this$0:Lcom/sec/tetheringprovision/TetheringProvisionActivity;

[COLOR=Red]--    const/4 v1, 0x0
[/COLOR][COLOR=YellowGreen]++    const/4 v1, -0x1[/COLOR]

    #calls: Lcom/sec/tetheringprovision/TetheringProvisionActivity;->sendResult(I)V
     invoke-static {v0, v1},  Lcom/sec/tetheringprovision/TetheringProvisionActivity;->access$800(Lcom/sec/tetheringprovision/TetheringProvisionActivity;I)V

&&

/com/sec/tetheringprovision/TetheringProvisionActivity$TetheringPlanCheckTask.smali
--change auth links to localhost

Code:

   .line 1081
    const-string v0, "[COLOR=Red]127.0.0.1[/COLOR]"

     iput-object v0, p0,  Lcom/sec/tetheringprovision/TetheringProvisionActivity$TetheringPlanCheckTask;->ATTTetheringPlanCheckURL:Ljava/lang/String;

    .line 1082
    const-string v0, "[COLOR=Red]127.0.0.1[/COLOR]"

     iput-object v0, p0,  Lcom/sec/tetheringprovision/TetheringProvisionActivity$TetheringPlanCheckTask;->ATTMHSPlanCheckURL:Ljava/lang/String;

It fails the authentication quickly and anonymously by calling localhost (127.0.0.1) and allows hot spot enabling after.

The modified APK is attached. Rename existing APK and ODEX file to .BAK then place modded APK in system/app and reboot.

UPDATE: The attached APK is out of date and obsolete. See my dev-resources thread for an updated deodexed system installer based on the newest system release that includes this mod.

Does the S4 need to be rooted to use Foxfi/pdanet?

Supposedly not, that's their selling point.

I guess I'm not that familiar with .smali but how did you get root permission?

Harsh much? The "original" Android development forum had one topic and one sticky. I didn't even think to look there. My bad but seriously I hate when people post rude comments that don't even answer the question asked. Keep it to yourself if you don't feel like being helpful.

Since you modified the apk already we should be able to push the apk into the system and change the permissions using a root Explorer. Even if you mess up this apk won't brink anything. The worst case is your tethering just won't work. You can even just rename the old system files to .bak just incase.

Can you post up the modified apk...

You installed PDAnet from their website, right? The Foxfi branded version is blocked for AT&T customers on the play store

yes I did, I only installed FoxFi off the PDA site because it could be tired before you buy. Has anyone else gotten the free one to work? Or do you need to have the full version?

The free version works fine for me, no extra configuration or anything. Are you rooted?

no I am full stock, but I do need this to work. I will re-download and re-install to see if that works.

I'm rooted, but PDAnet never requested root access. Does it give you a specific error or message?

it just stops and says "unfortunately, FoxFi has stopped

Nottach · Apr 30, 2013

I think you guys should make a discussion thread for FoxFi in another section.
Please keep discussion here in regard to the posted mod.

okay, I got it to work :good:
I had gone to the FoxFi website like it said in the store, I now went to PDANet+ site and downloaded the bundle and it worked, thanks for the tip this will help a lot until the custom ROMs come out.
