General After October Update, my SM-F711B (Europe Version) lost 5G - Samsung Galaxy Z Flip 3

Hi, all
I bought Z Flip 3 5G from amazon.de (Unlocked Europe Version) and use it in China Mainland.
CMCC 5g coverage is very good and fast, SMF-711B with very good 5G/LTE frequency band support worked very well before I upgraded in October Update (F711BXXU2AUJ7).
It can only use 4G now, and when I try to use *#*#4636#*#* to force it to connect to NR (5G), it will directly lose the connection.
Same as
https://twitter.com/i/web/status/1459056362348969993, Z Fold 3 seems to have encountered the same problem.
I try to reset the network setting, It still only 4G.
I don't want to reset my phone to validate the problem, what else can we do to deal with this problem?
Thanks.

Wait please for next firmware.

Hey there,
Did you get the xxxxUJB update? Just got it on my EUX csc. Curious if you did and if it fixed your issue.

Yes, I get F711BXXS2AUJB,
But I still can't get 5G, only 4G(LTE).
Maybe the reason why is baseband firmware?

That is interesting. I guess it will probably get fixed with Android 12. I don't have 5G in my area, so I can't test but as soon as I go to an area with 5G I will test.

Down here its working

LM-V500N Korean KT version in UK on Vodafone 5G

Hi, I'm using the LM-V500N Korean KT version in the UK on the VODAFONE network. Everything else appears to be working ok except for 5G.
It doesn't connect to the 5G service, only 3G and LTE showing.
Does anyone have any help or suggestions on what could be wrong?
My SIM and 5G coverage is fine as I can use my SIM in a Samsung Galaxy S10 5G and it works fine on 5G.
Currently only EE sells the V50 in the UK, so I was wondering if the V50 is only compatible with the EE 5G service in the UK?
Ok since nobody is able to help answer, my conclusion is that my V50 is 5G locked specifically to KT carrier in Korea.
Only 4G LTE is working fine in UK.
So I guess 5G won't work until I can reflash the phone to European firmware?
Could this unlock the 5G ?
Thanks
where did you get the phone and do you get volte or wificalling..also how loud the phone gets trough wired jack.thanks

Yes, crossflashing is the key, but we don't have a working lgup right now. Let's hope we will.
just sound tested a lg v50 in uk today and is better than my htc 10 volume wise...i think i will go for korean version from wonda as its not worth paying EE 1800 over 2 years.SHOULD I PUSH THE BUY BUTTON OR NOT?
I'll recommend Korean version as it's camera has features like super steady mode which european I don't think it has. Also updates. Yes lg updates are very frequently on Korean. Sometimes twice a month.
In the meantime maybe we get working the 5G. Or maybe not.... For me 5g is not that important. The audio quality is. And the camera, it wasn't in the past, but now that I'm spoiled, it is.
dont really care either about 5g.....not worth price vs coverage...but audio is a MUST.Curious thing is that a month ago i listened to a v50 in an EE shop ,but today a different shop and the audio loudness was twice as the previous one.

By the way the bank aplications work on korean version.Especially barclays aplication or any banks app?
Yes all my banking Apps work in the UK on my V50 Korean KT version. I've not had any issues.
I use Natwest, Virgin Money, Nationwide.
The only app that did not work properly was Sky Go, but this is also now fixed with the latest update I received 2 weeks ago. V500N11r

Where did you bought your phone from?
I bought my V50 on ebay from Korean seller Funphone-International. The price was very good and converted to less than £370 Inc shipping.
I really want tbe 5G to work, so hoping for cross-flash soon as possible.

Hello, I've emailed KT Mobile Service because I was curious if the V500N KT version, which I own too, really locks 5G in a way in their phones and here is their answer:
My question: How can I use the 5G network in my country, Portugal, with my network (NOS). Is it possible, do you have to unlock the 5G network?
-Answer: Originally LG V50 is unlocked also KT doesn't have Carrier lock.
If your provider has 5G service you can use 5G but if they don't, you can not use it.
To check your service, you need to contact LG or your mobile provider.
I don't know why you can't use 5G in your network, but it's not because of KT network.
most of the countries require to have the 5g phones registered to their network and also you need a 5g plan.
Thanks for helping.
I'm on Vodafone Network with 5G service enabled, but the V50 still doesn't work on 5G service. A really mystery.
I've put my SIM card into a different Samsung 5G phone and it works with 5G service showing, so my SIM is ok.
Hi, I have done some more investigations and I used the hidden service menu 5457#*500# to check which radio bands my v500n was using.
Under the Multi Band Selection menu I can see all the LTE bands up to B41 listed and selected, however there is no B78 band in the list.
Does that mean my v500n does not support B78 band which I think is the Vodafone 5G band in the UK?
Can anyone else check their service menu and confirm if B78 band is present?
Thanks
korean is 5g locked ....was confirmed on telegram group
Ok thanks
Is that the reason why LTE band B78 is not appearing in the menu list?
Previous answer from Danix004 is saying 5G is not locked and confirmed by email from KT.
-Answer: Originally LG V50 is unlocked also KT doesn't have Carrier lock
If 5G is truely locked then did anyone on Telegram know how to unlock 5G on the Korean KT version?
Thanks
cant be done until root is possible
Ok I received the official Android 10 update yesterday and my phone is now at version V500N20b
Working really smooth with all the new features.
But still no 5G.

can such problems be fixed by software? I thought you will need hardware for that; not sure how this work.

How to enable carrier aggregation on Note 20 Ultra?

Hi Guys,
Does anyone know how to enable carrier aggregation on unlocked Note 20 Ultra (Hong Kong version but should be the same for all other regions)?
Thanks!
Hi,
It's enabled by default, and I doubt you can disable it unless you force it to use only one band (with Activity Launcher, search for a phone activity with the word "hidden"), but even then you won't be able to turn off intra band aggregation.
You can see if your phone connects well to multiple frequencies with an app called NetMonster

Thanks a lot!
The problem is that I imported the Snapdragon version from Hong Kong and it seems (from what I read about imported S20 Ultra) it doesnt have EU specific carrier aggregation so needs to be changed via Qualcomm tools and PC.
So I wanted to know the method for Note 20 too.
We don't know Carrier Aggregation combinations what HK-version support but there is way to list these from modem log. I think HK-version have Qualcomm so SCAT-method is best: https://mt-tech.fi/en/how-to-get-4g...tions-from-your-android-phone/#Scat_(Qualcomm
What region you try use? In Europe i think Carrier Aggregation should work but in US i think it doesn't support any combinations. If you just share QMDL modem log i can list all Carrier Aggregation combinations from your device.

Actually, carrier aggregation worked out of the box, without any fancy setup. Depending on network strength it shows either 2 or 3 bands combined.
So this issue is resolved.

Yes, I live in the UK and HK version works like a dream - except 5G that doesn't work yet...
And, yes, it should not fully work in the US as the bands are different. But in the US you guys have native Snapdragon variant (1 sim though) that should do it.

So I ordered A us note 20 ultra then i read on here that these past couple of North American samsung devices Arent been able to be rooted, I didn’t know this because my last Samsung phone was a s8+ but anyway i returned it and ordered the N980 varient because im a dumbass and i have never been on a android phone without root and i have owned androids for over 8 years. I just Hope the 4g service is not bad, I already sacrificed 5g for it but i need 4g ?:crying:

I also migrated from S8 and the difference is huge.
I was also a heavy root user but stopped rooting phones as use Knox and banking apps heavily and neither works with root. TBH I didn't miss root much, we can do almost everything without rooting nowadays.
Hi Guys. Anybody can explain me why Note 20 ultra Hk version with Snapdragon Dual Sim doesn't work on 5G. I'm on UK on EE network, my brand new Note 20 Ultra just show me on the screen 4G+ speed. Is the problem with only that model on EE? Please help me. I got EE plan with 5G essential plan. Just want now is that model Sm-n9860 is compatible working on 5G in UK Networks.

Hi ALL. Thanks for sending me maps with 5G Coverage in EE UK. Looks like EE maps are different like real coverage maps with 5G range!!!
Anyway,acording that much accurate map I was check 2 places where 5G must working i Northampton UK ,and....still didnot pickup 5G on device screen. All the time is trong 4G+ only...
I got official message from Technician Team EE UK about SM-N9860,and it looks like that device on that moment is not compatible with EE 5G network .Is all good with 4G bands but not with 5G.

Thanks! I am among the first people in this forum who got SN-N9860 from Wonda, right after it was announced in HK.
The area I live in has no 5G yet so I had to travel to other places to test. The screenshot I posted was taken in Weybridge, near the high street. Three only has a tiny 5G area in Weybridge so I assume the speed and latency would be much better in London or other areas with better 5G coverage.
Carrier aggregation is not setup on the sm-n9860 to utilize the lte bands that USA use - for t-mobile anyways.
Im not sure if changing to csc bri might help for this. Probably someone from usa can confirm?
Maybe @inningsdefeat500 can confirm or not. I believe he has the same device and on T-Mobile USA.

Enable LTE+/4G+ in Europe for US model?

Hi,
I bought my pixel 4a in the USA last month and now that I am back to europe, I noticed that carrier aggregation is not working.
I found on google that on previous pixels, carrier aggregation only works for the region on where you bough the phone... so now, I am stuck with single band connection.
Is there any way to force enable LTE+/4G+ carrier aggregation / CA2 in Europe for an USA, unlocked model?
I don't have root... but I would root it if that means enabling that feature globally.
in Germany LTE+ is working out of the box. no root

Do you have the USA model and not the one released for EU?
And are you running Android 11?
I tried it in Portugal, UK, Spain and France on Vodafone and I couldn't get any 4G+ connectivity.
In the US I had no issues with LTE+ at all, only when I came back to europe.

I was hoping more for some mod perhaps.
I have checked that my phone is only connecting to one band, without aggregation.
It worked fine in the usa, but not in europe, so most likely, they lock it on the oem.
The bands are supported. I have B1,B3,B7,B20 available on my network, and they are all supported individually, but not aggregated.
It does look like the North American model is the G025J, and the European model is the G025N.
I do wonder if getting carrier aggregation working might require some special registration with the carrier though.
It doesn't require carrier registration. I have 3 sims and they all do 4g+ on my old galaxy note 8.
Pixel 3 had the same issue. They block carrier aggregation outside the region on where you bought the product, at the OEM level.
Maybe some dev knows how to unlock it on the software. I've see this for other brands.

Either we wait for Asus official US release maybe they will push an update to fix this or if you have to return it I say go with One plus 9 pro as it seems the most compatible with T-mobile plus it's sold by T-mobile themselves.
There is a reason that so many of the sellers tell you to check the bands before purchasing the device for a specific carrier. It should also be noted that you cannot change the bands with a software update.
You can find the bands on https://www.gsmarena.com/asus_rog_phone_5-10715.php and then head over to T-Mobile and check https://www.t-mobile.com/support/coverage/t-mobile-network#tech to compare
5G bands1, 2, 3, 5, 7, 8, 12, 20, 25, 28, 38, 40, 41, 66, 71, 77, 78, 79 SA/NSA - Version 1 1, 3, 7, 8, 20, 28, 38, 41, 77, 78, 79 SA/NSA - Version 2, Version 3
5G​
Frequencies that can provide 5G:
Band n71 (600 MHz)
Band n41 (2.5 GHz)
Band n260 (39 GHz)
Band n261 (28 GHz)
Version 1 supports 5G just like any Samsung device out there. Versions 2 and 3, on the other hand, only have LIMITED support for 5G and SA cannot be used (Settings -> Mobile Network -> 5G SA Mode)
What this means, in the simplest possible terms, is that you CAN get 5G if the specific tower where you connect provides the band that your device supports. Not to throw salt on it, but Version 2 and 3 also lack 4G band 12, which is the extended range band for T-Mobile.

I appreciate your help. The biggest question I have is how to tell which version of the phone you have. Mine at the time of purchase was listed as I005DA. I think Asus's biggest mistake was not releasing the phone in the US to begin with.
I am sorry for off topic.
I am planning on buying a ROG Phone 5 Tencent Games Editor phone, as this is the only version available to my local stores.
My question is, will this phone get OTA updates in international / global rom?

No it will not as far as I'm aware. But updating it is extremely easy. Just download the WW updates from Asus website and put it in your phone and restart the device and you should get a notification saying your phone has an update press on update and wait for it to finish. Your phone doesn't need to be rooted or anything at all.
I ended up returning it guys, not getting 5g is highly unacceptable in today's world. I got a Sony 1 ii for now it's quite good and gets 5g. Will get the Sony 1 iii in few months once it comes out.

There will be US version with proper US bands support somewhere in May or June according to press release. For now you have to wait for announcement

Excuse the rant for a minute, but there are a whole bunch of eBay and other sellers out there passing off their reflash devices as new, which makes it really hard for anyone to know what they bought because you get a Tencent device with a WW ROM and a manual in Chinese with the global apps.
The easiest way to know which device you have is to look in the box where the case and SIM pin were located. There should be a wax paper sheet with two black stickers on it. That will give you the exact model number.
If you got anything higher than 12GB RAM, it's Chinese. The European 16GB release isn't until the end of May and the Pro / Ultimate will come after that. The US was estimated for Q2, but it will also be the 12GB in the first release. If you got one claiming to be US, it's probably European (or Chinese).

This is super helpful information. Really want that US release. Could please you share the link where you got this information?

Question [Solved] Unlock 5G on Korean model SM-S908N in UK

Hello everyone, so I got the Korean version of S22 Ultra, and I cannot enable 5G here in the UK, but the N78 band is supported by the Korean version S22 Ultra, and all the carriers in the UK are using N78 (I have tried both O2 and Three, and I cannot enable 5G on either of them).
I then saw this post [Philippines]SM-N9860 TGY/BRI/CHC Snapdragon Users|5G Reception Fix, and I've tried to enter the secret code *#0808#, but the phone does not react to it, so I guess something strange is going on. Also, I've tried this method, which is not working, too.
Oh, and I just want to mention that the S21 Ultra I brought in China can enable 5G on Three's network, but not on O2. This is just confusing. Could anyone help me to enable 5G on this model? Thanks.
Have you tried on of those Android apps that check your network speed connection? it might just be that you're getting 5G speed but the icon is not showing due to your CSC.

Hi, thanks for the reply. No, I don't think so, because the download speed is significantly lower (500m vs 10-50m), as well as the latency. Also, "SIM card status" in the setting showed that the "Mobile data network type" is "LTE" instead of "NR NSA" (or SA, but there's no SA in UK as far as I know).
And even 4G (LTE) signal is weaker on the newer S22 Ultra model, does this have something to do with the frequency band as well?

Did you try that method listed in the guide with the Google phone dialer?
Also this might seem dumb but in Mobile Networks, is Network mode set to 5g?

Yes, I've tried both methods for One UI 3.0 and 4.0, and the secret code is just not working. I suspect that Samsung either changed the code or prevented it from running on the Korean model (since I saw one website claimed that those secret codes do work on S22 Ultra). And yes, 5G is enabled in the "Network mode" setting.

Only thing left I think of suggesting is maybe flashing a different CSC (a compatible one) to see if it works.

Thanks, I will look it up, but I hope/think there will be an easier method out there that are less risky than flashing CSC. Have a great day!

Yeah sorry it's not working out so far. But imo your best bet will be to back up your phone and change csc, though you can change CSC without losing data by not flashing the Home_CSC file I think. Great day! hope you fix it.

I'm in UK and after years away from xda,I've come here as a last resort,my 5g doesn't work also,when selecting network to 5g/4g,I get no signal,1 bar if I'm lucky,calls don't come through,then WiFi calling kicks in,so at the min,my temporary solution is the network is set to 3g/2g,I tried your mentioned code,screenshot shows what I get
Ok folks, here's what I found yesterday. Using the app called "Cellular-z", it appears that both my Korean version S22U and Chinese version S21U support 5G in the UK, sort of.
But they do not support N78 (or there's no N78 coverage/ the wall is too thick in my home etc), the only 5G NR bands they support is N1 (and N3? Although it feels more like an LTE+ band).
When switching on 5G in the control panel, both phones are using the 5G network, however, only the Chinese version phone shows the 5G icon. The Korean version does not. But the speed is significantly faster on both phone when 5G are enabled. It boosts from 50Mbps to 450-500Mbps in my home (But the latency is similar whether 5G is enabled, maybe because it's not using N78 or the wall is too thick).
I suspect the Korean version S22U only think N78 is the ''true 5G''.

Do they run at same speed? I have same issue here in mx, i have the us version (sm-s908u1) that apparently does not support the n78

Yes, they both have a download speed ~450Mbps, and latency ~25ms, which is what you expected from N1. N78 is not supported by both versions (or there is no coverage in my area, which I highly doubt that).
No issues using EE in UK. This pictures are from EH16 Edinburgh UK.
5G reception as good as on other 5G phones, didn't do any tricks or hacks, just works out of the box.

Same issue, I hope someone can solve this.
did someone found a solution to this? same issue with us version U U1. 5G doesn't appear. also tried to flash firmware with bootloader 2 (AVDC) but no luck. Google dialer method wont workanymore on oneui 4.0 i think.
I have this same issue with my s21+ SM-G996N, supposedly supports n78 bands (5G) but is stuck on LTE+ everywhere I go.
What carrier would I have to move to in order for 5g to work? Would it work with EE sims?
