My Xperia 1 is on HK firmware and hasn't gotten updates for over three months. Other regions have gotten the latest updates to fix the bugs but I still have to stand the crappy fingerprint sensor. Now I decide to flash SEA firmware but I hear that if I do so, I can't use VoLTE. Is that true? Does VoLTE support have anything to do with firmwares, SIMs, carriers, etc.? Thx.

If you live in HK, are using a local carrier and are on the HK firmware, then VoLTE will work.
If you live in HK and flash a non-HK firmware, VoLTE will no longer work.

HK firmware might have the necessary IMS profiles for VoLTE to work in China, which is why it could be working.
You could try flashing to a different regions firmware, if it still works, great. If not, you can flash back to the HK firmware.

In present situation I am busy working at home and have to use the phone a lot, so I have to think twice before doing so. That's why I asked the question first.?
Chinese carriers' VoLTE works on SEA firmware, but the signal strength is rather poor, you can simply flash the SEA firmware and receive OTA updates if you don't mind the signal problem. If you can't bear it, you can try this method to get VoLTE working normally. Beware that OTA updates would be unavailable, you'll have to repeat following steps every time you update.
1. Download both HK and SEA firmware.
2. Make a copy of these four files from HK firmware:
Code:
oem.map
oem_other.map
oem_other_X-FLASH-CUST-A2CD.sin
oem_X-FLASH-CUST-A2CD.sin
3. Paste them into SEA firmware folder.
4. Flash the firmware. (If you want to keep your data and apps, delete files starting with name "appslog diag userdata" before flashing.)

Thx very much! Could I try Taiwan firmware instead to get better signal and avoid replacing OEM files? Although it has slower updates than SEA one, it is still much faster than HK one. And it seems that no one complains its signal.

Update finished. I tried calling and no VoLTE icon appeared by the signal icon or on the UI of dialer, but LTE icon didn't change to H+/3G. Did that mean VoLTE was enabled?
Edit: VoLTE seems to work now. I typed *#*#4636#*#*, and in Phone Info I saw Voice Network Type is LTE, and Signal Strength is -82 dBm 58 asu which may be a good signal.

So I'm about to purchase the Xperia X and I live in the US. Is it better for me to buy the US version with a warranty and flash the firmware to enable the fingerprint sensor to work or should I buy the international version and if I did will it work okay in the US? Any help is greatly appreciated. Thank you.
if you bought US version. Just flash stock rom of other region. UK/europe/ MENA etc, and finger sensor will work. its more of software thing then hardware.
you can download other ftf (stockroms) using xperifirm under FLASHTOOL (www.flashtool.net)
Just flash european version of a firmware and you are good to go. I don't understand Sony's decision on this subject. Everyone has it available, but not USA.
You can flash the other regions firmware and BOOM! you have your fingerprint sensor activated.
The better thing you might not know is your device is still available for the official OTA, of that region. Just make sure you don't flash the 1 sim firmware for the 2 sims and vice versa..

I'm in the US and bought an imported ZX1 Compact with the fingerprint sensor enabled off of eBay, running Android 8.0.0. I'm getting notifications about an OTA system update from Sony; if I allow it will it disable the fingerprint sensor, or is that at a lower level than the OS?

If you've already flashed another firmware region that had the finger-print enabled, everything OTA update you're going to receive will be specified for that region devices and you will not lose finger-print function. Don't worry.
In a nutshell, just think that after flashing EU firmware (for example), you're owning the EU Xperia device, not US anymore!

i never tested that because USA firmware are for F5121 only and i have F5122,
but what you are saying make sense. if software updated only looks for the current version/build/region running on device irrespective of #imei & serial etc before pushing UPDATE then YES device once had USA firmware when left Sony Factory and Flashed EU firmware should get EU based OTA only ....
Please do let us know what happens
My question was about an imported G8441 that already had the fingerprint activated, I was worried that doing an OTA update in the US might overwrite it. However, based on robocopvn's comments above I went ahead and allowed the update (and one that came immediately after it) and everything is all good.

I actually clearly answer your question.
it's about the firmware you're running on your Xperia, not about the actually location you stay on earth when you hit the update button, thank you!
Hey everyone. I'm a proud new owner of a Realme 6. I bought it as being a global version (model RMX2001) 4/128GB.
I updated but found out that the firmware version was RMX2001_11.B.33. I think it must be a Russian Version even though I bought it through a spanish online retailer, since the box comes in russian.
I checked and there was a version for the Indian Region (RMX2001_11.B.37)with the same changelog as the one for the European Region (RMX2001_11.B.34). I downloaded the firmware for the European Region (RMX2001_11.B.34) and updated through the recovery mode.
Can someone explain to me what are the consequences of doing such a thing since I updated a RMX2001 model with a RMX2001EU model? Also, does this mean that from now on I'll get the OTA updates for the RMX2001EU model, European Region or only the ones for the RMX2001 model, whatever region I got?
Any other input regarding this subject is deeply appreciated. I'm curious more than anything. Thanks!
my phone is also a eu model, and didnt get the latest update to.
what i did is realme.com india region/market and find the o.zip RMX2001_11.B.37 and installed
everything working just fine for me. so i think all those phones are just the same..

I got my phone from amazon spain. I live in switzerland.
The latest OTA was B.30 for me. I downloaded B.37 from Realme Site and also updated via recovery.
Everything works however.
The hardware is definitely the same in all phones. But somethings still different. Some phones are able to unlock bootloader (india models I think) while EU models cant.

I definitely updated my Global Version with the EU Firmware. And in the settings I have the RMX2001_11.B.34 Version (which is actually the same as the RMX2001_11.B.37 according to the changelog, but not the size). I prefer the EU version since it may have less bloatware and ads due to the European restrictions. Also, I live in Portugal so I think it's better to use the EU version, unless a more recent version is available.

That's the strange part. It seems all roms are interchangeable, but then, what are the differences? Actually, how can one know what is their region? I say mine must be from Russia due to the text in the box and it also had a russian app installed. I updated with the EU rom and the model still is RMX2001 (not RMX2001EU), but the version is RMX2001_11.B.34. So I used a RMX2001EU_11.B.34 rom and it updated to the RMX2001_11.B.34 (missing the EU part). Furthermore, all package names and MD5 checksum are the same, when compared. Therefore, I actually think it is all the same and one can use any rom to update.

I didnt even realize that I downloaded the "non EU" rom from the india site. I honestly dont know if I had an EU rom when I first booted up my phone. I dont remember seeing EU in the OTA settings. However the latest OTA for me was the b.30, which is why I updated to b.37 manually because i thought higher number = latest update
Yeah its very weird. I only know that there is a global and an india version of the phone. We definitely have the global one or else we would have trouble with the 4g signal (or at least me here in switzerland)
EDIT: I think im a little confused now. I think you mean you had the RMX2001EU_11.A.34 (with the A)
There is A and B. Probably A for global and B for india
on 4pda forum some members mention that RU firmware supports "call recording", in all other roms(incl. EU) thats restricted due legal laws

You're right. I updated with the RMX2001EU_11.A.34 firmware version. Actually, I must have updated to the RMX2001_11.B.33 via OTA and then by updating with the RMX2001EU_11.B.34, I ended up with the build number RMX2001_11.A.34. At least that's what shows up.
I honestly think we can use whichever we want that any will work. I'll stick to the EU versions.

Well, both versions are supposed to bring the very same updates. I'd rather wanted to be on EU version too, even if its just for the file name and nothing else lol. My phone probably shipped with the A version and I mistakenly updated it to B

Hi. I want to buy a realme 6 in Spain but I need to record calls. The EU version does not allow to record calls, but the Indian Rom does include call recording. I have read that you installed the Indian version, can you see if you have the option to record calls?
To change rom is just install? There is no need to open bootloader, right? Can the Indian Rom be used in any country? I want to use in Spain
Thank you very much.

Could you answer me if this version with Russian box has the Brazilian Portuguese language?
How can I change the ROM?
It's my first time here, and much of this is new to me.
Anyways, I have an S21 (Snapdragon) with Multi-CSC? OYN, XAA/XAA/XAA that I use in Singapore. (SM-G991U)
I just learnt that apparently OTA updates are only given after the location of where the device is being used corresponds with the CSC.
What would my options be now, to update my phone? (Being able to have OTA updates would be preferable)
I know of (just learnt):
• Changing CSC via the phone app (using IMEI number). Never tried and I don't know if I'll get an error code. My main concern is that I'll not be able to update if I get firmware for Exynos instead (S21s in Singapore are Exynos), if I even get a Singaporean CSC on there.
• Flashing/ updating using Odin? (Heard it doesn't work anymore for changing CSC? I have One UI 3.1)
• Updating using ADB?
I'd love to learn something about this whole CSC mess too so I can understand what's happening and how everything works. And if it's not possible to get OTA updates, the best way to update my phone then. Thanks

Hi Mate
OTA are strictly Active CSC related , independent of the country you are using the phone. I have Spanish active CSC and i get the OTA in Panama
So you will get a new OTA as soon as available , the latest for you CSC (XAA) firmware is:
Date
Version
2021-06-27
11
PDA
CSC
G991U1UEU4AUF5
G991U1OYM4AUF5

https://www.sammobile.com/samsung/galaxy-s21/firmware/SM-G991U1/XAA/download/G991U1UEU4AUF5/1557396/
You can change the CSC but it will depend in what firmware you have and what CSC available that firmware has.
To your questions
1 You will not get an Exynos firmware in your phone as you can not force an exynos CSC into an Snapdragon , Singapore does not have Snapdragon firmware , so you can not force a Singapore CSC into your phone
2 Flashing new firmware does not change the CSC anymore ( in my case did not)
3 Update with ADB ? not sure what you mean but if you mean firmware , no is not possible

Thanks for the reply. Problem is, I've constantly checked for updates but I'm still stuck on the February patch which should actually have even came preinstalled on the phone. (basically, I've not received a single OTA update). This has led me to believe that the country you use your phone in affects receiving OTA updates.
I doubt there's other reasons why I wouldn't receive the updates (since other people have said that location/ connecting to the telco network? affects OTA updates).
Anyways, so to clarify, my only options to update then would be to use:
• Smart Switch (holding off because it is disabled from an app having device ownership)
• ADB (sideloading OTA update)
• Odin (unfamiliar with its uses)
I'm just looking for the path of least resistance to get my phone updated right now. And just to confirm, updating/ flashing (are they the same?) software will not wipe my phone?
Thanks.

Hi
Is hard to say what really going on , as i said I have an active CSC from one country and live in another and get the OTA with no problem ( lot of people do)
Easiest option for me would be doing updates manually with odin , download the correct firmware and flash using the home-csc file , that way the phone will not be wipe , will be like a regular OTA
Check this threads , here and here even if the thread talks about an exynos the procedure is still valid for a snapdragon
I still dont get OTAs. I flahed BTU, PHE and OXD but nothing. anyone else facing this?
I flahed with odin.
I have a Galaxy s21 olympic edition with number SM-G991Q and i am not receiving montly updates. The last update was the August 2021 patch and was installed on August 30th.
Also smart switch on Windows is not detecting Any new updates.
I tried to reset the device without luck getting new updates.
Does anybody has the same problems with the Galaxy s21 SM-G991Q not receiving updates?
I have this phone too, I also only got the August security update.
Don't worry, they probably lost their update schedule before switching to Android 12. I got updates yesterday for SM-G9910.
I have the same phone and find it odd that it doesn't show up on sammobile or anywhere else.
Does anyone know where to find original firmwares for it?
I have too G991Q and I need flash to XAA because I need BAND 20 LTE my country help me pls or altwrnative stock ROM?

I have a question about the G991Q, did any of you get the ESIM to work yet? It is currently software locked - in theory it should have it because it is a Snapdragon chip
Do you have Android 12 on G991Q already? Im checking every day but still no luck Should I install non olympic rom? Will that work? Thanks
@Corbik
This particular variant has yet to receive the stable One UI 4/Android 12 update.
@jussy
See here; the model number of this variant is SM-G991Q and the CSC is SJP. At the time of posting this, the latest available firmware version is G991QOPU1AUJ2.
my version is g9910 and still no update to android 12.
last version a11 octuber security update....
whats happend....
What standard version would be closest to G991Q? I tried to flash U1 ROM but no luck
Friends i'm also with the SM-G991Q olympic version.. I really need to switch to CSC from ZTO, to try to use VOLTE and WIFI CALLING from my operator in my country, Brazil!
Can someone please help me change CSC to ZTO ? I tried the tutorial above, but it doesn't open anything when typing the codes, were you able to change? I saw that it only works on android 10. but we are on android 11.
I saw that you have the option to change CSC ANDROID 11 via Samkey, but I believe it still doesn't have support for our SM-G991Q device.

Have you tried switching to another S21 variant's ROM with Snapdragon 888? it worked out ?
If it doesn't work, I think I found our ROM to perform restoration via ODIN, in brink event:

Yes I tried the U1 version since it should be US version with Snapdragon888.
That ROM you found, based on the numbers is exactly what is in my phone now.
I think I will just wait some more time to get official Android 12 update, hopefully our special version wont be forgotten
But If somebody know which ROM would also work for SM-G991Q and ideally would also support all languages and features (esim for example) please share

True, I hope we don't forget... friend know how I can change CSC to ZTO ?
Hi Everyone,
Can anyone help me with process for flashing UK version firmware of XQ-BC52 on Taiwan version of XQ-BC72. I need to know which firmware files such as ".ta" or any other files to be removed from firmware folder before flashing. The UK or US customization versions supports volte and Wifi calling in my country.
Currently the Taiwan firmware version is at 61.0.A.23.20 (android 11) and UK firmware version is at 61.1.A.2.211 (android 12)
Can I just flash the .oem files of UK firmware to TW firmware?. But, since device firmware versions are different, flashing may fail and corrupt the device. Can you confirm if this is safe to flash?.
Request your help!

I think yes but r u sure that customized UK fw supports voLTE and WIFI calling? the switches are in the settings? because I have the same model but with eea customized and have no volte or/and vowifi switches.... My carrier supports them btw
I've been told the customised SEA also has Volte and VoWifi wnabled, but I never got any joy out of it when I flashed it into my HK BC72 device. I have tried the previous firmware revision of the UK one, but nothing there either.

So if I flash it to my XQ-BC52 will it affect anything? I don't want to lose anything, but I want to use volte I have no idea why it isn't enabled when all of the carriers on my country support it
I would first update it to the newest TW Firmware and check if it works (so you can update, without loosing personal data).
If it still doesn't work, I would try the HK firmware, because of Over-The-Air–Updates (OTA). I have VoLTE and VoWifi in Switzerland with this firmware.
If it still doesn't work, try the BC-52 firmwares (but you loose OTA Updates).
Please just check after flashing a new firmware if you have the functions. If it works, first do a repair with Sony Companion before starting to install everything (like apps, files....). This makes a clean install and avoids a lot potential of failures/problems.
I bought the phone in Etoren and it is the model XQ-BC72, I live in the UK, and the update I received via OTA and is installed is 61.1.A.2.211 release-keys. you shouldn't, I guess Sony recognizes you're in the UK and installs the correct one

You won't lose your data if you explicitly tell it not to clear userdata off your phone, if that's what you mean. If, however, you're referring to certain functionalities I sometime hear of getting lost, then I myself haven't noticed such with all versions of firmware I have tried out so far.

I've yet to do a clean install, the way you have described it. I guess I'll do it just like that when I've given up on trying to activate VoLTE and VoWifi on my phone. It's interesting that your Hong Kong phone has that function over there. I suppose there is some substance in Sony's insistence that the one's network provider be engaged as well.
I was considering getting the Xperia 1 IV which would be a nice upgrade from my Xperia 1 II but with volte not working it would push me away. I managed to get it working on my Xperia 1 II by simply flashing SEA firmware. It was straight forward and has worked flawlessly with OTA updates. It doesn't look like the Xperia 1 IV will work that way. Even if I was to flash SEA firmware it looks like volte still wouldn't work. Come on Sony sort this problem out
