Question My Xperia 1 III is the Chinese version. Can I receive the OTA after I use the Taiwan system? - Sony Xperia 1 III

如题，最近台版、港版、都已经更新了61.0.A.11.92系统，但是我并没有收到，不清楚是不是因为我刷了TW版本的固件所导致的

MOD EDIT: English Translation Below
As mentioned above, the 61.0.A.11.92 system has been updated recently in Taiwan and Hong Kong, but I did not receive it. I don’t know if it’s caused by flashing the TW version of the firmware.

I have the Hong Kong version, Sony ha not released any update, only one app update.

Well, XPERIA 1 III is a special model - if you flash firmware of OTHER REGION, you will not be receiving any OTA. I found this by dialing *#*#7378423#*#* - normally you can find your region code in 'Software Info'. If you flash other version, Phone Software Version will be GLOBAL-C2-user, not HK or TW.

That's interesting. I have mine showing "GLOBAL-C2 - user". But I also received the 61.0.A.11.92 OTA.
(I didn't flash, btw.)

Just bought a 2nd hand Xperia 1 III 512G in China .
Seller said it's from H.K. but I'm not sure since the charger plug is 2 pins - For China & Taiwan
Not the 3 pins - For UK & HK . The charger type # shown as - AC-0540-CN
Current software version 61.0.A.23.20 / GLOBAL-C2 - user
Have all the Google apps and that's the reason I have to buy 2nd hand HK version since Chinese version don't have al the Google apps
My question .
It's 3/23 ; I still did not get OTA for Android 12 . I think this phone might be flashed before it's with me
How will I know if the phone is original from HK or original China version and flashed the ' GLOBAL-C2 ' software .

you have the china version, if you have the hk version the adapter is AC-0540-hk or XQZ-UC11 and the android 12, its regional, hong kong already has the android 12 update along time ago. whether yours is hk or china, if its f/w flashed, it makes no different.
btw the hong kong version is also a chinese version, but it has googles.b

Google search the below, xxx is your Sony Product Code. Click on the link that starts with software.sonymobile.com, usually the first one.
Code:
sony xxx
example from your screenshot would be as below.
Code:
sony 43040280
Search for the product code number on that page. If it matches, look at the <name> field at the top to find out your region.
It looks like you have a Customized_CN product.
You have a Chinese region phone flashed with HK firmware. In this case you will not get OTA, as mentioned by other people in this forum who tried flashing other region firmware. They do not get OTA.

Yes , I do believe above is just the situation I'm facing . What I don't understand is
Current version of 61.0.A.23.20 were OTA updated from earlier version when I go the phone and reset everything
Since I can get last OTA ; Why I can't get the Android 12 OTA

Is it possible you got scammed/lied to? That your phone is actually a China region phone with China region firmware. If it is then the behavior described above makes sense. As seen in the link below, the China region firmware was on the same version you are stuck on before receiving their Android 12 update.
Xperia 1 III (XQ-BC72) - Customized CN
The latest software and firmware versions for the Xperia 1 III (XQ-BC72) XperiCheck.com checks the Sony servers every 5 minutes to always display the latest information.
xpericheck.com
The China version only recently got the Android 12 update. And according to Chinese message board sources mentioned from:
New Update / Xperia 1 III / 61.1.A.4.78
forum.xda-developers.com
This latest update will be released on a new staggered schedule, meaning some phones get it first, others get it later in china. It means you may get the Android 12 update OTA later than expected. Maybe lets observe if you are getting the OTA update above. If you are, you may have been conned.
