Hi, I have also one Hong Kong variant bought by Internet.
I live in Spain and mostly of things works fine (only Samsung Pau and others small things don't work due to the different country).
I'm looking if it's possible to change the firm or CSC to another mostly European in order to have all of features available but I don't know if this is possible.
I know that GM-S9730 have Qualcomm inside and the others countries with Qualcomm are USA and Canada.
So could someone tell me if it's possible to use Spanish CSC over Hong Kong firmware or change to Canada (Multi-CSC) firmware?
Thanks in advance

Thanks @yakapa40 for your info. My question is if it's possible to change only CSC to have Spanish resources over TGY firm because I don't want to have an expensive brick...
I also updated my phone to ASC8 yesterday.

Sorry it's impossible. That model have only two CSC regions - TGY and CHC. For all other regions exept USA Samsung made S10 based on Exynos chip and it is incompatible with Qualcomm-based S10.

Can you guys who have the Hong Kong version of the S10 confirm whether there is settings in the contacts app to sort by last name & display by last name.
I'm asking because my daughter's S9 is a Hong Kong version and it doesn't have these settings

I am using the G9730 in Bulgaria and the only problem is with the Carrier Aggregation for VoLTE.

Here is the same like in your daughter's S9.

Use US contacts app

I would think US contacts app could be used to solve this issue. Surely some kindly XDA member could provide it for you.
zen123, out of curiosity, which order are your contact names displayed?

It's not issue, it's feature of the region. The programs can do nothing, the setting appears and disappears from the menu in different regions and depends on the value in the configuration files in the CSC.
As for me, I long ago changed in contacts places a surname and a name. Now I don't need this setting.

same situation in Italy. Any chance to enable at least the VOLTE functionality?
(carrier aggregation 4x4 is too complex...)

Awesome to know for the update! I checked just two or three days ago and it wasn't on samfrew.com just yet (for GM-G9750). I'm going to have to use Odin to update because I unlocked my bootloader. First time owning a Samsung and using Odin. Anyone else in the same boat?
Edit: actually, using Smart Switch does seem a lot less like a pain in the butt than Odin, so I'll do that.
Edit 2: updating via Smart Switch was super easy and didn't take very long at all. I was worried I might get a factory reset and have to restore everything, but that was not the case.

[WANTED][INFO] Post your CDA / Fingerprint number

From the Xperia X10 there is a easy method to change the firmware (debranding/branding) by changing the customization number in the build.prop. Similar threads exisits for those forums, but not yet for Xperia S. So I'm creating it here. Post yours and I will add to the first post as and when I get time. Even though the root isn't available, this will surely be useful for many.
How to find your customization number:
- Go to the dialer and press *#*#7378423#*#*
- Go to service info
- Go to software info
- Post the customization version (a way to check if your firmware is to look at the bookmark in the internet browser, a generic firmware version will always start up with the Sony mobile site)
Or look up the number in the build.prop file in /system
Please post the your location and any branding information as well.
Information is provided as given by the users. I'm just compiling it and not responsible for any wrong info.

Did you flash/debrand?
ah, that would be the reason then, i'm unlocked and upgraded to .67 nevermind then.
Edit: I will update this post later today with my partners system settings (unlocked but not flashed, so the info should be the same as T-Mobile NL) if they are different.
Edit 2: turns out it was flashed without me knowing, so same as me

I did, using the software on this forum. Only because the PC software kept insisting my software was up to date (I was on .62 before).
My phone is used in Australia on Telstra but was procured from Hong Kong. Firmware version on there before was Generic / World, but I didn't keep the customisation details.

lollipop region release chain

502 lollipop for france is out for g850f.
i have a question - there is a chain or a specific path that samsung follow for releasing updates in specific regions?
to be more specific when lollipop arrives in romania for galaxy alpha g850f?
i saw that orange lollipop has been released for g850f in romania, but for the unlocked variant is still missing!
if someone has any idea about region releases, please post some details and i will give a BIG THANKS!
michael
no one?
somebody? any clues?
WTF?
There is no Orange Lollipop ... there is only a late update to KITKAT from Orange Romania that as usual is the crappiest mobile provider ever!
yep, sorry, my bad!
i saw something wrong.
still, about when will the update drops nearby, from first french release, there is a country pattern or something?
Nope, it could be hours, days, weeks, months depending on the mobile providers. The France release could be a test phase and after if results are positive they could go global.
Problems with software could lengthen the process and the recent apps button bug that some experienced is bound to do just that.
Or you could update to lollipop with odin. But so far only the french version is out.
5.0.2 is out in france. You can download the update from sammobile.com. Go to their site, search for galaxy alpha in firmware section, then follow the links to download it. When done, follow the tutorial on how to install odin and drivers for windows PC.I did this, first try and worked like a charm. I'm using 'international' 850F. It's really a simple procedure.
yes, but...
i have installed the french version, but i need my country version when comes out from the motive that i hope is less buggy...
there are tests now to ensure the other versions are bugless, but i dont know how many weeks we must wait for.
in the end they will push the 5.1.1 update, cuz 5.0.2 is difficult to make it clean considering google got issues too with him
when on android we have to be able to control oure frustrations regarding updates, especially from oure carriers ...so...
KEEP CALM AND WAIT FOR IT cuz im not calm and im reconsider my next strategy of buying future phone
anyone with some news about when lollipop is released in other regions? ...for G850F
there are 2 weeks from france release?
how much do we have to wait?
i hope not another 2...
The best sourse for news remains Sammobile. When the update is ready, it will be posted there. We just have to have patience.

It is carrier specific. The french version is basically a test release to the public and all carriers get the same firmware. It is up to them to release that version related to them.
Basically dont blame samsung, ask your carrier when it will be released
what carrier? i'm a free carrier user! i relay on a carrier just with contract but phone was bought from shop. i can choose any carrier i want! so... who gives the updates for unlocked phones? it's samsung, i think.
corret me if not

Your csc is your carrier since thats what you were asking for, in my case my unbranded DBT alpha still has to wait for debital, the german unbranded version.
Also since you dont care, then you have your version with the french release.

Doesnt matter, it will work on the SM-G850F regardless and its a new build. Plus this is a thread about Region updates.
I would flash but I dont have time at the moment but I am sure its featured with multiple CSC's so it should not effect the use to anyones area. All SM-G850F have the same hardware and features. The difference in CSC are region tailored with specific bloatware and minor differences like lockscreen shortcuts and signal icons (some use LTE and others will have 4G). Most importantly this build has a new changelog which means Samsung may have fixed some issues with the French build.
Can i get it on danish?

Helloo,
So, if i flash the new UAE, can i still get everything on Danish? I mean, is there multiple language on? English would be fine too ..
Another thing, would this trigger knox? Thinking its not a custom, but a official ROM from Samsung, so it shouldn't trigger, am i right or?
I haven't flashed it yet but I believe it will have all supported languages. It won't trip Knox as long as its official from Samsung it won't touch knox.

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

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.

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.

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.

Change CSC on Samsung Galaxy Devices with *#272*IMEI number# (replace the red text with your device’s IMEI number), not working any more.
(You can change CSC on Root Devices.) ​NOTE If bootloader modification to Unlocked state does not trip KNOX, U can uses this tutorial to changes CSC .
NO PROOF
Important Notes:
Only unlocking the bootloader of your Samsung Galaxy device will not trip the KNOX counter.
However, flashing a custom binary such as TWRP or Magisk patched AP firmware will trip it. This may have an effect on your device’s official warranty, so make sure that you check with your regional Samsung support if you’re concerned.
Furthermore, apps like Secure Folder, Samsung Pay, etc rely on KNOX integrity to function. Once KNOX is tripped (that’s after you flash a custom binary), such apps will stop working.
Samsung Galaxy devices with a Snapdragon chipset that are sold in the USA and Canada come with a non-unlockable bootloader. The only way to unlock the bootloader on US Snapdragon devices is by using a paid service such as UNSAMLOCK.

You should see the “OEM unlocking” option greyed out in an ON position stating – “Bootloader already unlocked”.​
Why Should I Change CSC?​There are a plethora of reasons why you might need to change your Samsung device’s CSC code. For example, if you have purchased an unlocked (carrier unlocked, not bootloader unlocked!) device from any other country, then it would have the language and device settings for that foreign country. Along the same lines, the APN settings and the pre-installed apps will also be of that region only. To overcome this issue, you could easily change the CSC on your Samsung device and flash the firmware of your home country.
What’s CSC on Samsung?​CSC is the abbreviated form of “Consumer Software Customization” or “Country Specific Code“. CSC is an essential component of Samsung firmware binaries and it contains customized settings, system configurations, localizations, and geo-specific things such as the system language, APN settings, and carrier-branding.
How to Check or Find CSC on Samsung Devices​You can check the CSC of your Galaxy device by dialing a code on your device’s dialer itself. The secret code you need to dial is *#1234#
My result.
Look at the line CSC: T225 OLM1 BVGB
it's separated into 3 part. Device model , CSC code , firmware version no.
Since I flashed the CSC code "OLM" (Multi-CSC region XEV "Vietnam") firmware and switched to THL (Thailand) Region CSC, it shows me both the CSCs.
In the 3rd line, you can see the activated CSC, that is THL. This simply means that I’ll keep getting official OTA updates.
Note: After finished installing , bootloader auto relocked again. then before flashing you must installed Stock firmware , toggle on Debugging mode and OEM unlock in developer options. No root.
Click to expand...
Click to collapse
Now, let’s come to the 3rd line in the above screenshot: THL(1)/THL(2)/THL(3).
The first CSC value, that is THL in my case, shows the active CSC. This determines the access to services and updates. You will receive updates on this channel. This is also the country used for Samsung’s Beta programs in case you want to join one.
The second value "THL” shows that my Galaxy Tab A7 Lite is a One-SIM variant. This value only shows what SIM you have inside, and doesn’t affect any aspect of the experience.
The 3rd CSC value, that is THL again, shows the country code for which the Samsung device has been manufactured and configured. This one cannot be changed and it doesn’t need to. In case you get the phone from a carrier, this value will have the locked CSC code. In case the other values don’t match, your carrier can refuse warranty service (since warranty goes through the carrier in case you’re on a contract.

NOT LIKE A12 wants to return back to A11
May I ask is this useable also when switch from different multi CSC? I have XTC now and planning to switch to DBT. And both have different group to try ANdroid 13 if it fixes my light sensor since A11 downgrade is not possible

Question Unlocking full band 28 on the Ace Pro. Possible?

So, will it be possible to unlock n28? The Ace Pro uses band 28A for LTE as well as N28A for 5G. But Reliance Jio, the operator in India uses N28B and that's not compatible with the Chinese version. I wonder if flashing a global rom will fix it. The reason I want the Ace Pro is due to the 512GB variant. The Indian as well as European variant doesn't have 512GB max. So, is it possible to unlock full n28? I don't have the phone at the moment, but planning to get the Ace Pro, probably during the 11/11 sale on Aliexpress.
Here are the bands the Ace Pro supports. The problem here is the N28A
4G: FDD-LTE bands 1/2/3/4/5/7/8/18/19/20/26/28A
5G: NR SA:n1/n3/n5/n8/n20/n28A/n38/n40/n41/n77/n78
I'm hoping it's possible to unlock using Qualcomm tools QPST and QXDM.
Will await your replies.
Wait for Jio Phone 5G launch to verify whether N28B is available for the device or not in India ? BTW most of the Chinese Phone launched in 2022 do support N28A not sure about N28B.
Devices that mention support for N28, (support both A & B)
N28 SPEED IS SLOW BUT NETWORK COVERAGE IS GOOD.
10T Global Bands
FDD-LTE: B1/B2/B3/B4/B5/B7/B8/B12/B13/B17/B18/B19/B20/B25/B26/B28/B30/B32/B66/B71
TDD-LTE: B38/B39/B40/B41
SA: n1/n2/n3/n5/n7/n8/n20/n25/n28/n30/n38/n40/n41/n66/n71/n77/n78
NSA: n1/n2/n3/n5/n7/n8/n20/n25/n28/n30/n38/n40/n41/n66/n71/n77/n78
In China N28A Frequency is- n28a (Uplink: 703MHz-733MHz, Downlink: 758MHz-788MHz)
In India N28A Frequency is- n28a (Uplink: 723MHz-748MHz, Downlink: 778MHz-803MHz)
N28 WILL WORK WITH JIO CHECK BOTH CHINA AND INDIAN FREQUENCY IN THE CHART.

Hey thanks, although I won't need the Chinese 10t due to reasons specified below.

Yes it's slow, but not that slow. Should give a good 10 to 20Mbps on 5G indoors when the tower is about a km or two away even with a bare minimum of 10MHz block.

Thanks. Was checking a forum and found out your said frequencies for China are correct.
Xiaomi Community
c.mi.com
This thread shows that the Chinese N28A frequencies differ a lot. Funnily enough, the Indian variant has the same modem and the same band config as the Chinese variant. India and China both have 1Gbps 4G modems whereas the EU variant is packed with a 2Gbps modem. Now I won't get the entire 2Gbps, but I would be able to attain a good speed over the other phones thanks to the speedier modem. So, I've dropped the idea of getting the 512GB version. Will get the EU variant for now, and then plan on upgrading to a better phone with mmWave by 2025 to 2026.
I do thank you for your help though! It looks like you got the attachment from Esmail's spectrum chart on Onlytech.

I will flash a custom rom that should work with Jio VoWifi when they come out, so that won't be a problem. I'm finding out if it's worth buying the phone during the Aliexpress 11/11 sale, or wait until March 2023 for the custom roms.
@gonetask another thing to add, the global variant has more band combos as compared to the Chinese variant which I assume has the same combinations as the Indian variant.
Global: https://cacombos.com/device/CPH2415
China: https://cacombos.com/device/PG110
As you can see, there are over 3.2k combinations in the global variant which are pretty important, whereas the Chinese variant has just 190 combinations.
Does simply changing from the chinese rom to the global rom enable the global bands?
Edit: nevermind, found my answer. Looks like you need to modify the nvram which is not overwritten when switching roms. it looks like OnePlus has, in the past, included a toolkit which allows for enabling/disabling bands called RFtoolkit along with another apk called Comms or Bands or something like that.
