[TOOL] Device ID Changer for Oreo

CoNsTaR · Apr 16, 2018

　　Android 8 (Oreo) has a major behavior change on how device ID is manipulated, this tool helps you Query / Modify the IDs on Oreo in a programmatic way.

For further information about the behavior changes of device ID in Oreo, see the page: https://developer.android.com/about/versions/oreo/android-8.0-changes.html#privacy-all

Looking for the App?

See This New Threadhttps://forum.xda-developers.com/android/general/app-device-id-changer-oreo-13-aprv0-9-2-t3777299

How to use it:

Root privilege is NEEDED.
Download the proper version for your phone - if not sure, armv7 is **[pretty much]** working on most phones.
You might need adb tools / Terminal Emulator.
Copy the executable binary downloaded to /cache or other ext filesystems.
Give 0755 permission to the executable.
Assign/Query IDs.

Command Usage:

See the link: https://github.com/CoNsTaRs/oreo_device_id_changer/blob/master/README.md

Step By Step Querying/Assigning IDs:

Have the downloaded exctuable placed at the root of your SD card.
Use either adb/Terminal Emulator to run the commands below.

Setting up

Code:

su                                 # Gain root permission if available
cp /sdcard/[EXECUTABLE] /cache/    # Copy executable from /sdcard to /cache
chmod 0755 /cache/[EXECUTABLE]     # Set permission

Querying

Query current device ID for package [PACKAGE].

Code:

/cache/[EXECUTABLE] -q -p [PACKAGE]

Query the default device ID for package [PACKAGE].

Code:

/cache/[EXECUTABLE] -Q -p [PACKAGE]

Assigning

Make a backup first using this command.

Code:

/cache/[EXECUTABLE] -b /sdcard/settings-ssaid.xml.bak

Preview changes. (This is not changing anything, just previewing the modification(s).)

Code:

/cache/[EXECUTABLE] -a [ID] -p [PACKAGE]

If satisfied with the result given from the command above, run the following command to make the changes.
Assign the ID [ID] to the package [PACKAGE] directly.

Code:

/cache/[EXECUTABLE] -i -a [ID] -p [PACKAGE]

※ Substitute [EXECUTABLE] to the file name of the executable, [ID] to the appreciated ID, and [PACKAGE] to the package name in the commands above.

Do not forget to REBOOT your phone after changing IDs.

New IDs go into effect only after a reboot is performed.

Just one question. Your notes contradict themselves.

First you say you cannot query and assign at the same time

Then you say to query and assign at the same time set ......the flags.

So which is true? Can you set and query in fact at the same time or not?

Thanks

I don't really find the contradiction in my note.

To clarify, I'll restate them again for you.

Querying both ID - NOT possible
Assigning both ID - Possible
Querying and Assigning in one command - NOT possible

Edit: whoops, just found the instructions

See the Release Page for downloads.

Use this tool through adb or terminal emulator are both possible.

I've just updated the original post, hope that gives more information.

I'm still not sure to where to put the executable so i can execute it with the terminal emulator

Any ext filesystem should be good.

Step by step:

Copy/Download the executable to the root of your SD card
Follow the commands below

Code:

su
cp /sdcard/dvcid-armv7 /cache/
chmod 0755 /cache/dvcid-armv7
/cache/dvcid-armv7 -q -p com.android.example    # Run commands as you want

it looks like it works, if i query the id i get the new id that i set, but the app wich i'm trying to use it on recognize that it is still the same phone, maybe i'm doing something wrong, thanks anyway!

Don't forget to REBOOT your phone after changing IDs.
The changes take place after the next boot.

Hi

Firstly thanks for your efforts; I've been after a device id tool since I updated to Oreo.

My system:
Xiaomi MIX (ARM64) running Resurrection Remix Oreo.

I used the ARM64 version of your tool and the query part worked fine.
The trial change reported that the id I had supplied wasn't a 16 digit number (it was) but I could use --force to do it anyway, which I did, and it appeared to work.
I made the actual change (again using --force) and rebooted.
Querying the id for the package now shows that it has reverted to the original id.

Any ideas? If there's anything I can do to help (logs...), please let me know.

Hi, thanks for your report.

Can you try again with This Release, and see if your problems are still there.

mmidders · Mar 29, 2018 at 12:49 AM

Thanks for the swift response.

I still get an error about the deviceid I'm using and have to use the --force switch, but the change worked with the above realease and has persisted after a reboot. Thanks muchly.

Thanks for the feedback. I'm happy it helps.
It appears that I mistaken thought that device IDs are numbers which actually are not.
I'll make some improvements based on your feedback.

They're sixteen digit hex strings, so technically numbers, just not in decimal.

Thanks for your help.

Just as an addendum, I found it quite difficult to find out where the ssaid settings file was in oreo; maybe because I'm new to Android development, but for google and anyone else:
Android Oreo 8.1 Device ID SSAID /data/system/users/0/settings_ssaid.xml

Bhabesh98 · Mar 31, 2018 at 3:51 PM

If it is possible.. Then please Make an App to Change the Device id

changing id through Commands is little bit complicated.. I m searching for Changing ID in my oreo Device with any module or App. But nothing working till now

it ll be very helpful and easy to me and to others too by an App to Change id.. Thanks

Hi Bhabesh,
I totally understand what you're saying, and it was actually my intention to make an android app in the first place I started this project.
However, I've hardly no experience of developing android apps as of the last time I did it was years ago.
Specifically, it apparently will take a lot of time for me to re-learn it, get my knowledge up to date, and maintain such a project.
The problem is, I'm currently busy working on another project which consumes most of my free time, and have no time to pay attention to this.
For these reasons, I'm not likely to get into this shortly, but I will finally make it an app for sure.
Hope you can understand my situation, if I made it, eventually, I'll as soon update this thread and let you know.
