[GUIDE] Automatic dual sim switching on latest official OTA

[harpreet.s]

Anyone able to get code for OP6 version 9.0.7 !!
I tried 175 , 177 both not working for me

 

[alexbergsland]

I had success. Oneplus 5 with Pie
I discovered that with Pie it is necessary another step between 2 and 3, because the step 2 now gives .cdex files (compact dex) instead of the .dex files, and jadx (at least the versions I tried) can read only .dex files.
In the github page of vdexExtractor I found a section about the vdexExtractor#compact-dex-converter, that is necessary to convert .cdex to .dex.
I used the Linux x86-64 - Statically compiled binaries, the shared libraries version didn't work on my Virtual Machine with linux Mint (I have only windows 10 on my pc)
Using that converter I obtained the .dex files that jadx can read and follow step 3 and 4 of the guide.
I hope to be of some help

Awesome!
At last, I tried this before but gave up, I had it working before Pie, but have been toggling it on and odd manually since Pie.
This time I got it and for my Oneplus 5 it was 176.
I used compact_dex_converters but that produced a filename like .cdex.new, I renamed that to .dex and opened it with jadx-gui and did a search with "Code" ticked, just to clarify for others.

Does this fully disable the second SIM Slot? Like if you run this does it make your device think it only has one SIM Slot? If that's the case has anyone tried using this on Google Fi to see if they can enable RCS on their device?

Took forever, but finally got it working. All via Windows. I have a OnePlus 5T and my number was also 176. OS vers 9.0.9
-Used latest vdexExtractor.exe from https://github.com/fOmey/vdexExtractor/tree/master/bin
-Then referenced kevinminions9 post from https://github.com/anestisb/vdexExtractor/issues/23 to download the android version of the converter tool, and then followed the directions to push the converter and pull the dex files back to my laptop
-Couldn't get Jadx working for some reason, so used "Bytecode-Viewer" to find the magic number using the path mentioned in the OP

It works fine also on OnePlus 5 9.0.11 :good:

Thx a lot

This is some Godmode level stuff right here. You're amazing!

Has anyone found the command line for android 11?
The command line above worked fine for a Oneplus 8 running Android 10, but couldn't find the number for the new version.

 

[harpreet.s]

There goes for Android11 , works on NORD , not checked but last digit 1 should be replaced with 0 for sim1
service call isub 41 i32 1 i32 1 (enable sim2)
service call isub 41 i32 0 i32 1 (disable sim2)

Sorry but it doesn't work with the Op8. Do you have the source of your information so that I can work on the subject?

 

[harpreet.s]

Assuming you have root , can you try this -
su shell -c 'service call isub 41 i32 0 i32 1'

This should disable sim2.

You can decompile framework.jar , all source is there for how this code is called.

Thanks, works kind of (on Nord), however it turns on or off sim1 instead of sim2, easy fix would be to swap the cards
Allthough that will make for some calls from the wrong number as I have had them the other way around for a couple of years on the OnePlus 5.
Changing the last digit to 0 does nothing for me.

Also, I did have to use

su shell -c 'service call isub 41 i32 0 i32 1'

as a Run Shell command in Tasker for it to work on my Nord.

 

[alexbergsland]

Strange, I did swap the cards around, but now it's sim2 that gets toggled, which still is my private sim and not the one I want to toggle.

 

[harpreet.s]

Just play with these 3 commands , any 2 will disable your 2 sim cards -
su shell -c 'service call isub 41 i32 0 i32 1'
su shell -c 'service call isub 41 i32 0 i32 2'
su shell -c 'service call isub 41 i32 0 i32 0'

and to enable that sim , replace the 0 in between of command with 1.

For me first 2 commands work for disabling sim , although command ending with 1 disables sim2 while command ending with 2 disables sim1. It is because the 1,2 at end are sub id values. You can know what value is assigned to your sim card , you can run in dialler *#*#4636#*#* and go to phone information.

 

[alexbergsland]

su shell -c 'service call isub 41 i32 0 i32 2

Yeah, thanks, that one did it!

If anyone is interested how to disable one SIM per need, there is a way to do it with Tasker app (root needed). Here is howto.

I found an easier way to get magic number after some research.
I tried and it works on Android 10 -

Disable Sim 2 (Root)
