How To Guide Converting Japanese Pixel 6 to Global version - Google Pixel 6

I live in a country with no Pixel availability and end up purchasing one in Japan.
Limitations(mostly forced shutter and screenshot sound) on Japan phones can be pretty annoying, so I researched a bit on how to remove those.
Search leads me to this reply by @ziand for same trick but on Pixel 5. Turns out Pixel 6 is different but similar. So I'll summarize what I've done here.
At the same time @ziand may also work on a magisk module or something when possible, doing the same thing but in a much safer way. Once his work is done please switch to his method.
Disclaimer
I'm not familiar with law in every country but doing this could have risk. Research before acting.
The instructions requires basic Linux/Android knowledge. You could brick your phone if not knowing what you're doing. You can always wait for ziand's work for more safety.
I confirm this works on my phone. But I'm not responsible for anything happens on yours. Use at your own risk.

This should be permanent, you can also revert root if you want.

Hi,
Someone tried this on pixel 5a?
I dealing with the same anoying japanese problem.

Curious if this would adversely affect NFC function as the Japanese model is NFC-F.

Did you flash Factory Image with erasing data, factory reset ?
The converting is success if you have:
- new Model ID in bootloader - Barcode -SKU;
- new Model ID in Settings - About phone - Regulatory Labels;
- appeared option to switch off the sound in settings of stock Camera app.
Do you have all of them ? Show some pictures.

---

Do you have possibility to insert another sim not softbank and maybe not Japanese carrier at all ? it is interesting how with this sound on other pixels 6 not Japanese versions there in Japan.

This is known issue as even global Pixel do have forced shutter and screenshot sound when a Japanese carrier SIM is inserted, no matter where you use it. In this case MID changing method can't help you.
The module from the other thread may work though as it's directly modifying system UI APK:
GitHub - AndroPlus-org/magisk-module-pixel6: Google Pixel 6シリーズ以降向けのMagiskモジュールです。
Google Pixel 6シリーズ以降向けのMagiskモジュールです。. Contribute to AndroPlus-org/magisk-module-pixel6 development by creating an account on GitHub.
github.com
Downside would be you'll always need Magisk installed. You can have a try.

Of course, because Pixel 6 and Pixel 6 pro are different devices.
Pixel 6 is Product ID "oriole" and Pixel 6 pro Product ID "raven". For now the module v2.05 and less is for Pixel 6 only.
Send me to PM some info from your device to upgrade this for Pixel 6 pro too. No problem, I will add everything into the script for converting.

I use HarryShan's guide. And change GF5KQ to GLU0G for my Pixel 6 Pro. It worked. My phone don't have sound when capture sceen and take photo.
Thank you.

You can also use a gcam mod camera for silent shutter . There used to be a workaround for the silent camera by simswapping in Japan but it was removed or patched in android 12. A Japanese sim will always enable sounds
