I just received my Xperia 1 IV USA version today from FocusCamera.com today, I was a little skeptical if it was even the USA version, since it wasn`t shipping from Sony until next week, I originally had pre-ordered on Sony website, then with a little looking around I had found the USA version on ebay in-stock, then I saw the seller name and went to there website yesterday and verified with there live chat that in fact it was in stock and would ship, so I ordered and use next day air shipping, everything works flawless and actually has the 5G bands like my Pixel 6 Pro, so I can get proper 5g speeds, on Band N71, That was missing from the Global version I was using 2 weeks ago, now I need the Firmware from Sony so I can root. I`m a happy camper
Congratulations
What carrier are you using it on?

yeah I had t-mobile then I switched to GoogleFi last month, and wifi calling works perfect, inside my work place service from all carriers suck, since it big steel building, but my Xperia 1 IV will say emergency calls only, but I can receive calls and make calls and receive text, ad everything just like had full bars of carrier service.
I guess you were not able to root it?
To know exactly how capable the device is then its necessary take modem logs and let smart people parse it.

Unfortunately not, so this will be going back for refund, I can`t justify spending 1600.00 on phone and not able to root and do with it what I want with it, but there`s always the global version I could go back too, I`m going return it and wait and see if Sony does eventually allow it to unlock the bootloader, until then I`ll just use my Pixel 6 pro for now.
Can you please let me know if :
a. the NA model has Dual SIM support ?
b. Face unlock works (was told the fingerprint scanner is a bit finicky)

a. there is dual sim support, but you will lose the micosd card, because Sim 2 uses the microsd slot
b. no face unlock and both global and USA version`s the fingerprint readers worked perfect.
Is the 5G SA standalone or NSA only?
Should be both on all versions, USA model difference is mmWave support.
Would also like to know if they finally enabled 5G SA on T-Mobile with this year models.

You can know that without buying phone. Download the firmware with xperifirm, extract modem.img and use ELFextract to extract your hw variants .mbn file. This will reveal the carrier/band policy files (in policyman folder) which live in the modem. There you can see which bands are enabled for specific operators and if they are enabled for SA and NSA.

Thanks for the tip. I got as far as extracting mbn files. I can't seem to find ELFextract tool you've mentioned. I'm assuming this is different than readelf utility.

Hi everyone
I am in the UK and bought the Note 4 Global version, as in the UK my provider uses Band 20
I am on Tesco, which piggy-backs the O2 network
However, on inserting the sim I receive the No Network error.
Tesco give me the usual "we don't sell those handsets so we can't provide technical support blah blah" "It must be locked blah blah"
The sim is fine as it was in his iPhone 5 (and still is because this won't connect to Tesco)
The Mobile Networks setting has been changed to what was on the previous phone, but with no joy.
Any ideas anyone?
Thanks in advance
Edit for stupidity:
Android 7.0 NRD90M
MIUI ver 9.0.5.0
Have you tried any other sim card in the phone? You can get one of those cheapie PAYG sims (for example, EE) from Tesco or your corner shop and see whether it has the same problem (which might point to a hardware issue or something funny going on with your ROM). I am not sure why you would have had to change the mobile networks setting. That should not be necessary at all.

I have an EE pay monthly sim. Tried that. Same thing. No Network.
Irony in the fact that it says TESCO 4G in the top band by the clock when he puts his sim in the Note 4 and 2 bars on connection.

Ok, it definitely should work with EE, and so this is clearly not a Tesco mobile problem. Either the hardware is faulty or the ROM (particularly the modem drivers) is faulty. You might want to return the phone.

It looks like the same issue (on a different Xiaomi phone). The solution is probably the same - flashing the appropriate modem (firmware) files, or flashing a new complete ROM. I wasn't sure you wanted to go down that route, as it would give the vendor an escape route if something goes awry, or if the process doesn't solve the problem.

If the phone sees the signal and it does detect 4g ,than the phone is ok.
The problem is that 110db . That's practically dead zone. I would say your location is the problem. I know you said that Samsung has 2 bars but this is crappy phone .
Just to be sure, can you check in a a place with strong 4g signal?

It seems that you will have to go down that route, unless you return the phone. Whether it works or not will depend on whether it is a hardware problem or just a ROM/firmware problem.
By the way, there is a firmware repository here: https://forum.xda-developers.com/showpost.php?p=73534612&postcount=89
This requires you to have TWRP recovery.

These things are often a hit-and-miss affair, especially when buying from outside the EU. I bought mine (two) from eBay (UK and Ireland based sellers) - much easier to get refunds via PayPal (and more likely to get a proper Global ROM). But it is possible that your problem will be fixed by flashing the latest global stable ROM.
Update
Took it to the Tesco Phone Shop this morning and they couldn't get any of their settings to work. Consistently No Network. Wouldn't even connect to the Tesco guy's Vodafone sim.
Tried a Virgin sim and it wouldn't connect either
Guessing something wrong with the global rom now?
As with Note 3, MIUI 8 and the missing modem drivers?
Sparked an email back to Geekbuying to see what they can do
Thanks all

Possibly - but there is also a possibility that it is a hardware problem. That will only become clear after successfully flashing a complete ROM (global or otherwise). Whether the ROM is global or China should not have any effect on connecting to a phone network (especially EE).
Which version of MIUI are you on? Try updating of there is an update available and see if that helps.
Just got my Xperia 1 III (XQ-BC72) couple days ago, flashed SEA firmware with no problems so far. Except too bad it doesn't support Volte in Canada, which used to be fine on my previous Xperia 1 J9110 with SEA firmware as well.
I was wandering is that possible to flash it with US firmware to unlock that, plus features like more 5G bands support?
Anything helpful would be appreciated.

I flashed US firmware yesterday but it appears that it still wont work with Verizon even though all the 4G bands are there. I could care less about 5G where I live. I have CMDA less feature activated too but still no go. Worked fine on the HK version of Xperia 5 II so I though I would be OK on this one as well.
@i7killpii you are unlikely to get VoLTE to work (aside from maybe on T-Mobile). Its possible that a Canadian provider may also allow it but I doubt it. You also wont get access to more bands just by switching firmware. Whatever bands came with the phone is all you have access too.
@charlatan01 you can follow the directions here: https://forum.xda-developers.com/t/guide-flashing-xq-at51-firmware-on-xq-at52-device.4147027/
These are for the Xperia 1 II but its the same process for the 1 III as well. If you use Verizon and somehow figure out to make it work, let me know. Please note, flashing firmware will erase everything. Also I am not responsible for any bricking or issues you may get into. It worked for me on the first try.
I flashed my XQ-BC72 using XQ-BC62 rom before. I cannot afford 5G plan so I didn't try. About VoLTE, I am using Fido and the carrier services are not available (including VoWiFi, VoLTE, showing 4G instead of LTE, etc.). Also I got a lot of problems such as LTE connection disconnection about every 30 seconds. So I flashed it back to TW rom. Still all carrier services are not available but at least the LTE is functioning.
I've searched about the carrier services issues. It seems it's because the carrier isn't cooperating with Google so no carrier configuration is available (I'm not sure because fido has android phones on their website).

Thanks for the follow-up. I managed to cancel my order for the Asia version and am going to snag the NA version when I can.
try only flashing /OEM partition with the OEM files of the firmware from your area.
Usually that brings VoLTE functionality and stuff

I called Verizon and got them to add the IMEI to my phone line along with CMDA-less feature. It actually worked. I can make phone calls and send/receive texts so it appears its possible to get Verizon to work on Asian model. However, VoLTE is a different story. I dont think I will get that work.
I was able to flash my XQ-BC62 (US) model with the XQ-BC42 (JP) firmware using newflasher. Everything seems to work OK except the mobile radio. The radio is completely disabled (as reported by *#*#4636#*#* status screens), not just unable to connect. The hardware is still fine since flashing back to XQ-BC62 firmware gets a signal again.
Unfortunately I need to use XQ-BC42 as the other firmware images are missing the VoLTE support for my JP carrier and it fails to provision. At best I can force it into data only mode by setting radio to LTE only. The carrier does not support 3G at all.
Extra steps I tried:
- Perform factory reset after flashing
- Swap out the files for the modem firmware from the US firmware and reflash
Has anyone had luck with this, or are there any additional steps I might need to try?
This phone keeps getting worse. I literally bought it to use in the US and Japan. Sony support said it is officially unsupported by all US telcos. No SA 5G, no VoNR, no VoWiFi. Now I hear that it doesn't work in Japan?!
I already know it's close to useless in French Polynesia despite having all the right radio bands.
You can try swapping both OEM-xxx.sin files from the XQ-BC42 firmware folder into the XQ-BC62 firmware folder and flash there XQ-BC62 firmware with that, then you should be able to get VoLTE and modem working at the same time.
If that doesn't work, there are other methods but they will require root access.

But you will need the profiles for your vendor. One could play around and try to integrate these profiles into your XQ-BC62 Firmware and see if this would work out. But well - keep fingers crossed that you don't brick anything.

No, they don't support overseas models. I don't know if it's ignorance around the security or an attempt to prop up their own phone sales. Both are honestly believable over here.
This is the only reasonably priced major carrier plan with unlimited international roaming included (ahamo from NTT Docomo). Not being able to use the 1 iii sucks but I'll just write the 1 iii off if it can't be fixed and continue using my JP variant 1 ii.

Why did you get yourself the "American" Variant? Docomo has, as well as softbank, there own supported devices. Kind of similar to TMobile US. Sounds you are spending most of the time in japan. I know that the Docomo version isn't so well supported regarding updates though ...

I have the US model - the same as this thread topic.
It's Sony tech support themselves that told me that there is no carrier support for the US model in the US. It was such an incredible conversation that I saved it. An excerpt:
(Adrian) said :I'm asking you this because at this moment Verizon is currently the only U.S. carrier that supports 5G on the Xperia PRO model. The 5G network service is
not currently available in the Xperia 1 III model and this is why you're getting that
issue. In this particular case we recommend you to check with your phone carrier
if there is a way for them either to provide a different network service or if there is
a work around on their system for you to use your Xperia phone with their service

Don't repeat Sony's claim about 5G being in development. T-Mobile has been running SA 5G where I live for nearly 2 years. I've done side-by-side comparisons between an older phone with SA 5G and my Xperia by swapping the SIM. The XPeria has a lot of "no service" problems because it's using SA 5G channel aggregations without having SA 5G. There's another thread on this - Sony has explicitly disabled SA 5G on all US NR bands. https://cacombos.com/device/XQ-BC62
The Sony phone was unstable roaming in PF and could not see several 3G, LTE, and 5G bands that were available to it. Again, an older phone worked better. I used a much more modern coverage map than your 2017 document.
I haven't been to Japan with this my Xperia yet due to COVID restrictions, but I normally spend ~2 weeks a year there. I know my old phone works well there so I'm going to be mad if a new Xperia is stuck looking for old 3G cells that only exist in subways.
I have an XQ-BC42 that I'm using in Europe with 5G working (which isn't supported officially).
All I had to do was flash the XQ-BC42 firmware with the following 3 files replaced by their equivalents from the XQ-BC52 firmware:
* modem_X-FLASH-ALL-4BA8.sin

So in your case you just have to take the 3 files above from the XQ-BC42 firmware and combine them with everything else from XQ-BC62 firmware and flash that.
From what I've gathered, assuming your phone has XQ-BC62 firmware on it already, it might only be necessary to flash the XQ-BC42 modem files and nothing else, but I haven't tested this.
I'm assuming you can swap other files too but what definitely didn't work for me was the oem .sin files from another model's firmware. I don't know if there's something incompatible about the XQ-BC42 compared with other models but using non-XQ-BC42 oem .sin files disabled my radio completely.

I have the US model - the same as this thread topic.
It's Sony tech support themselves that told me that there is no carrier support for the US model in the US. It was such an incredible conversation that I saved it. An excerpt:
Don't repeat Sony's claim about 5G being in development. T-Mobile has been running SA 5G where I live for nearly 2 years. I've done side-by-side comparisons between an older phone with SA 5G and my Xperia by swapping the SIM. The XPeria has a lot of "no service" problems because it's using SA 5G channel aggregations without having SA 5G. There's another thread on this - Sony has explicitly disabled SA 5G on all US NR bands. https://cacombos.com/device/XQ-BC62
The Sony phone was unstable roaming in PF and could not see several 3G, LTE, and 5G bands that were available to it. Again, an older phone worked better. I used a much more modern coverage map than your 2017 document.
I haven't been to Japan with this my Xperia yet due to COVID restrictions, but I normally spend ~2 weeks a year there. I know my old phone works well there so I'm going to be mad if a new Xperia is stuck looking for old 3G cells that only exist in subways.

no, i am not saying it is under development. The standards are there. How ever - in different regions some of the 5g is still not rolled out / will never been seen (mmWave,SA 5G - at least for private customers).
Well i read the message you quoted a bit different - and i would love to know what other carriers have to say about that.
I personally would find it completly unlogic to sell a device like the Pro, which is said in your excerpt, to have 5G support on Verizon - but then sell the 5G capable phones which have this deactivated at all.
Supported Major U.S. Carriers: Verizon (5G), T-Mobile (4G), AT&T (4G)*
*As of 9/27/2021, please consult with your network operator to ensure compatibility with their network.

Might be, that t-mobile is using some more advanced features. how ever: here where i live most phones up to now don't support 5G SA, at least thats what the carriers say, as there are updates needed to make this work. So we will see here some selected phones using 5G SA - as the providers are working together with SOME of the major OEMs.
You can know ask who is responsible for supporting 5G SA or providing updates... As much as i got from t-mobile usa, they where always not really open to devices, which they don't sell directly ....

sad to hear - but just out of curiosity:
Why did you get yourself the "American" Variant? Docomo has, as well as softbank, there own supported devices. Kind of similar to TMobile US. Sounds you are spending most of the time in japan. I know that the Docomo version isn't so well supported regarding updates though ...

I happened to be in the US at the time to pre-order and it wasn't clear that Sony would release an unlocked dual-SIM model for the JP market. I checked the radio bands before purchasing but all of this client provisioning stuff is new to me. Seems like all these laws were made to force carriers to unlock their phones / allow any standards compliant phone on their networks, and then they find this loophole with provisioning that requires more than just a SIM card...

You can try swapping both OEM-xxx.sin files from the XQ-BC42 firmware folder into the XQ-BC62 firmware folder and flash there XQ-BC62 firmware with that, then you should be able to get VoLTE and modem working at the same time.
If that doesn't work, there are other methods but they will require root access.

Unfortunately this didn't work. But I did learn that the radio problem isn't an issue with the firmware itself.
Immediately after flashing the mobile radio was OK and I could use it with my alternate SIM card. As soon as I inserted the JP SIM card it triggered OMA client provisioning and killed the radio. After this happened not even the US SIM card would work anymore, and any radio related configurations can no longer be changed.
My hypotheses at this point are either (a) the client provisioning step found something off with my phone and forced it to lock down (not sure if client provisioning has the authority to do this though), (b) the client provisioning is interacting with the modem firmware in a JP-specific way and the US modem firmware is borked by this.

I have an XQ-BC42 that I'm using in Europe with 5G working (which isn't supported officially).

Other than the issue after provisioning the OEM files from the JP model did work for me. If (b) is true then flashing both the oem and modem files might be a solution. I'll give that a try!

Same result, no radio after client provisioning runs and it stays borked even with the SIM card swapped out.

Have you tried with only the modem files taken from the XQ-BC42 firmware? Might be worth a shot.
Also, it might be worth asking on the 5ch thread if you speak Japanese.

I spent a few more days trying various combinations of flashing, factory resets, etc. and finally have it working. I don't know if this is the only way to achieve this, but I can share the sequence I did most recently. This was inspired by the discussions in that 5ch thread - thanks for the link!
1. Install JP variant ROM with full factory reset.
2. Install the JP SIM card and wait for provisioning to finish. The radio stops working at this point.
3. Create and flash a hybrid ROM, using the modem*.sin files from the JP variant and everything else from the original (US) variant. Do NOT factory reset.
4. Set the correct APN (sp-mode.net for ドコモ).
After this both the JP and US SIM cards are working.
@cjmovie
Congrats on this achievement! Hope you can now use your device as you wished!
Hello there!
So I've been watching this forum for a solution a long time ago now and I've seen that there's a plenty of you, who didn't find any solution just like me. Because I didn't want to ruin my phone with unlocking and root. But I managed to make it work, not just volte, but vowifi too. All you need is another phone that works on VoLTE (and/or vowifi) in the same country ( same carrier is better bu not requirement). Put your SIM card in that phone, enable VoLTE (and VoWifi) and put it back in your Xperia. For me, it worked with a T-mobile HU SIM card (They don't even have on sell this phone ). It was in my iPhone 8 plus, it had working VoLTE and VoWifi. When I put it in my Xperia both options popped up in the settings and they both worked like a charm. My perso SIM is a Yettel HU one (I bought the Xperia from them), it isn't VoLTE enabled by carrier, so I'll contact them today about it.
Hope, you guys manage to make them work too

Tried that yesterday, didn't work still. If I am right, I believe that the issue is that there is no network provider in my country that supports (has customised firmware) this phone.
I do a bit of travelling every once in a while; so my best bet is taking my phone in by a network provider in a country where this phone is sold and get that network provider to flash their firmware in it, buy a local sim card and have them make VoLTE work in it. Then my home SIM card should work with VoLTE afterwards.

Sorry to hear that it didn't work for you. In my country we have only one carrier (Yettel HU) that sells this phone. They use the international one XQ-BC52 Customised EEA. I bought it from them, so mine is also that. Idk but it did work for me. So they don't have own firmware. They had on Xperia z3, since then they sell unlocked devices.
My model is originally the xq62 but i flashed hybrid of xq72 SEA to make it work but it didnt so i just kept using it as it is. I tried this on this and still it dosent work. Maybe if i flash same model as yours xq52 or the original 62. Too much flashing and checking.....

I have no idea why does it work for some and why it doesn't for others. My perso SIM was voLTE disabled in their system. Maybe it's your case too. Call your provider's tech support (or so) and ask them about it, worth a try

Telecom Italy appear to never turn on VoLTE if not specifically asked, even if your telecom app say VoLTE enabled. I also had to ask multiple times till i was able o talk with an higher tier "technician".
This remember me when at work (AASP) we need to talk with ACS to solve an issue with various customers Apple products. Sometimes only escalating to higher tier will allow us to solve something. Lower tier employee, even for ISP, sometimes are not able/allowed to disclose something

Mine didn't work in my iPhone either. It turned out that it can be disabled in 2-ways at my carrier. There's an android and ios disable option after it has been enabled, still no volte, but after I put it in iPhone (volte works) and put it back then it worked in Xperia too maybe that's a coincidence but I searched the internet a bit and I found some guys who made it work like this too.

What is the app bro?
Hi, i bought a unlocked xq-bc62 in US. I travel a lot and discovered 5G won't work in several carriers networks, no matter what I do in the phone ( I spend more time outside US). I called the carriers support and they confirmed their network doesn't have any lock preventing the use of overseas 5G bought phones. So far, I tried to use it in Portugal, UK, Ireland and Brazil but 5G is not recognized by the phone. I changed the sim for a 5G local one, changed ASN, manually chose network (5G ones are not displayed) and no success. I even tried to pray, but again, no success. I contacted Sony Support and they said phone will only work in 5G in 2 of the 3 main carriers in US and not outside US, despite the phone tech specs says it will work in all the frequencys used by above carriers. There are some threads here that confirm xq-bc62 Is not a full 5g phone. All said and done, my Question: is it possible to flash another region Image like xq-bc52 or xq-bc72 in this hardware? Will it work fine and, mainly, will 5G networks be accessible outside US? Tks
Some times its hardware but you can try mtk engineer mode settings there may be something of use there
If you can get the original vendor file usually have (user low ship...) its usually international
Unless the phone is using 4.5G and not real 5G

Yep, the US models have numerous disabled features and run late on updates. I've also noticed it's crippled or disabled while roaming. I'm not sure if it's directly from disabled features or it it has been blocked by telcos because it malfunctions. (It gets kicked off cell towers in the US)
The US model has slightly different radio hardware so I would expect problems flashing the OS from another region. There are some tricks for changing the feature lists that might be a safer bet.

How would one check what is and isn't turned on network wise??
I was able to flash the XQ-BC52 ROM in my XQ-BC62 hardware. So far, working fine in 4G+, but I´m in area with no 5G coverage. Tomorrow I will go to an 5G area and check f it worked. If not, I will try the XQ-BC72. I will keep you posted.

Maybe something along the lines of Getting VoLTE and VoWiFi on unlisted carriers by flashing mbn file or 5II/1&5III VoLTE patch. [Guide to release the root] or https://band.radio/
I haven't rooted yet so I haven't tried them. I bring a T-Mobile LG Velvet 5G with me when I travel. It's a little slower but doesn't have all the telco problems.
Test done, xqbc-52 doesn't see 5G network as well. XQ-BC72 SEA is a no go, don't even recognize the SIM card in the phone.
Will try another firmwares and the tweaks kevinmcmurtrie mentioned above, but my feeling is: I paid the 5G price for the Phone and actually got a a 4G Phone. Very frustrated with Sony. Thinking seriously about going back to Samsung.

But hey here's the pros, best physical camera sensors, Micro SD card Slot and headphone jack...
UPDATE!!! 5G is working!!!!! After Several Attempts, I finally got 5G. What worked for me, in Claro BR Network, was flash a Hybrid ROM. I Flashed A XQ-BC52 ROM with Modem files from XQ-BC72. So far everything working as it should. My only concern, next month I will be in Germany, may I have trouble in LTE over there with XQ-BC72 modems?

Ok, major setback. it worked for 3 hours and when I turned on my second Sim card the phone 5G was gone. Turned it off, reset radio configs, but no success. Apparently turning the second sim on override the BC72 configs. Time to get serious now and root the phone, what I'm very reluctant to do.
