Switch from sm-n9860 taiwan to hong kong

[Revivexda]

Hi, I have a sm-n9860 with the taiwan samsung pay and I want to switch to the Hong Kong sw version (both are sm-n9860) as I travel there often and I'd like to add the public transportation card on my phone.
How can I do that? Will a clean install work?
Thanks

Should do as both stock ROMs are for SM-N9860 variant.

So is the stock Chinese ROM compatible with this variant (I'm using it - I switched from Taiwan stock ROM) ).

Make sure you backup all your data to an external memory first, then clean flash the HK stock ROM via ODIN.

Have you done anything special?

I was on android 11 BRI

I downloaded android 12 TGY using frija

I Removed my accounts from my phone, removed SIM & SD, and entered download mode

I've used Odin3 v3.14.1_3B_PatcheD to flash it, by simply adding the 4 files

Once done, I'm still on BRI

What else can I try?

I give up.
I tried downgrading and it won't work.
I tried flashing TGY again and it stays on BRI.
Oh well, I guess that I'll never have the Octopus card on my phone.
