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

A lot of people including myself have the problem with 2.1 where we cant send text messages longer than a single text.
But it says here that vodafone have worked with SE to fix the issue and have released an updated 2.1 firmware.
Is this firmware available yet for flashing? if it is where can i download it?
It tells you in the link you posted. Update/Repair using PC Companion.
But i have a rooted and unbranded phone with the nordic firmware. If i was to try and update i'd imagine PCC would not detect a vodafone firmware and not update to it... or that would not matter if SE have fixed all firmwares and not just done a vodafone fix, does anyone know? would PCC even work correctly with a flashed phone?

Sorry, from your OP it sounded like you were on vodaphone firmware already. The easiest way to flash it back to vodaphone is by the CDA change method as you are rooted.
see here:-
http://forum.xda-developers.com/showthread.php?t=824711
you will need to change the codes to 1234-4579
Although as you were having problems with it on nordic firmware it would say to me that its not a firmware issue, more likely a network one but i'm no expert.
also, probably worth you keeping an eye on this thread, and PM Jeff-SEAnswers ...

Thanks mate
I dont think it's a network issue because other people have the same problem on all kinds of networks and in different countries.
I have a vodafone SIM but i've always had a unlocked/unbranded phone... what would happen if i tried to use PCC to put the new firmware on my phone without flashing back to my phones original firmware? and are all UK firmwares the same or would this one with the fix be specifically for vodafone?

Using the above method I linked to would install the newest Vodafone firmware (ie. The 'fixed' one in your link). It doesn't matter what firmware you are currently on. No, all UK firmwares are different, some will come with provider settings preinstalled, specific apps or features enabled/disabled depending on network. If you don't want to go back to branded try flashing to generic UK 2.1 using flash tool, thats what i'm on and I never had any text problems.
Think i'll just try flashing to the firmware you use and see if that fixes it... could you link me to the UK firmware you used? Cheers again!

X10i Generic UK - http://www.multiupload.com/TVLQVFW4OA
just put the files in the 'firmware' folder of flashtool then run it.
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!
Could someone please explain why my NEW Xz1 phone (and Sony companion) think that I have the latest updates when according to XperiFirm much newer versions exist. Currently I have:
47.1.A.2.281 currently installed on the phone yet
47.1.A.12.235 is the latest available in other geographical areas.
Is it ok to flash this latest one from a different geographical area onto my phone ?
I live in New Zealand and was considering flashing a UK Customized 47.1.A.12.235
I would use Flashtool by Androxyde.
Would this void my warranty ?
Why is it that Sony put out updates but we just don't get to see them - who's dragging the chain here ?
And since posting the above I'm aware that two more updates have happened:
47.1.A.12.270
47.1.A.16.20
WTF is going on ? Why are we not getting ANY updates ?

You can flash firmware from other region, but you may lose FOTA update pushes, this means you can only upgrade your firmware through Flashtool or other similar tools in the future.
As for the warranty, I have no idea about it, but I have already flashed my Chinese version XZ1 to Malaysian firmware, since the Chinese firmware does not have any Google apps, and it just works fine, I also replaced the oem.sin file from Chinese firmware to Malaysian firmware in order to have VoLTE enabled.
But as I mentioned before, I lose FOTA after flashed my phone, so I have to download the entire firmware via XperiFirm and flash it manually. If you flash the original firmware without modifications, you may not lose FOTA, if you do so, please tell me!
EDIT: You can only flash firmware matches your model, so don't flash a G8342 firmware into a G8341 or other.
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.

please explain method flash rom for resolve this problem . thank you.
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.
