Hello everyone
Just got my hands on the Galaxy A90 5G from south korea SM-A908N KTC. I live in kuwait city got the 5G internet package from Viva telecom but can't seem to connect to the 5G network shows only LTE+ where ever i go even close to a 5G node. Checked our supported frequency band the phone supports it. Noticed in the settings there is a KT twophone service and when starting the phone 5G KT logo appears. My guess it's locked to KT telecom network.
So far only 3 firmwares available for this phone china, korea UK. Can i change the firmware to another region like UK BTU change the CSC file and check if it work?
Thank you and sorry if this thread is not suppose to be posted here i have low posts

Hi, I have the same issue, have u managed to solve this issue, did u manage to switch the korean version with UK version

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.
I remember there are certain china phones dont work with vodafone B20 4g band.
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.
eu model, android 11 stock

Resting Wi_Fi, mobile & Bluetooth...............or factory reset doesn't work I assume.
Maybe try this:

Thanks, but I am talking about using the US version in EU. The EU version will naturally work in EU.

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.
I received a Note 20 Ultra (Snapdragon) from a relative residing in the US. I am currently in Malaysia, the Exynos region. If I am not mistaken, the 4G+ here uses a combination of band 3 and 7.
On my note 8 device, using my simcard, my mobile connection would show 4G+ in certain areas and 4G in the outskirts. On the note 20 (Snapdragon) it remains on LTE and never LTE+ / LTE-A.
Would it be possible for me to change my csc from XAA (US) to XME (Malaysia)? If so how?
Or is there a way for me to force the carrier aggregation to occur?

I don't think you can change CSC from American region to non American. Not sure much can be done to enable CA

Exactly. Same as me using my HK version in the USA. No CA, I can't change csc to any usa devices.
What you could do is compare CA combos for all USA devices and see which one closely matches your region and then take it from there.

I think this hardware doesn't have defined Carrier Aggregation combinations used outside from US. Here is listed some supported Carrier Aggregation combinations here if this is same model what you have: https://cacombos.com/device/SM-G988U . You can contribute to webpage cacombo.com/contribute using scat logging method to provide more logs to complete list so then we know.
I think you can change CSC because Qualcomm vs Exynos - complete different device.
Qualcomm version does not support Band 3 (LTE). Only Exynos version supports it.
Hello i have S22 ultra SM9080 and somtime while im an in place where connection is bad like in elevator , 4g+ goes to H+ but after i come out in good place it does not returns to 4G+ himself i have to use airplane mode and then again i have 4g+
What could be the reason ?
What network?
I had similar with a note 10 when I changed provider. Was told to reset network settings. It worked for a short time. What actually fixed it was changing provider.

Hi Everyone,
I purchased a S22 Ultra while I was living in EU. It is the Exynos Variant. I moved back to India and I can no longer connect to any 5G providers. My SIM supports 5G and 5G works when the same SIM is inserted on any other phone. The model is SM-S908B/DS and is on the latest One UI 5.1. I have tried contacting Samsung support but none of them seem to have any answer for this.
Does anyone has the same problem or the Exynos Variant doesn't support 5G outside of Europe?
Apologies in advance if there's already a discussion thread for the same.
Regards
Yash

S908B Exynos is not sold in India so it probably doesn't contain 5G configs for Indian carriers. Good luck contacting Samsung India or Indian carriers, they highly won't provide support for S908B.
There's a thread about enabling all 4G/5G bands, but it's for Snapdragon only.
Best way is to trade in your device for an S23U S918B (sold everywhere except USA, Canada, China, HK, Taiwan and South Korea)

Did you try to reset all network settings only in settings? Or may be try to change region CSC.

I don't have S908B, but might worth a try.
Use Samfw tool to change to every possible CSC, see if it works.
Sorry bro, my fault.
