Hello guys, I live in Europe and I own the Korean Samsung Galaxy Fold 5G version SM-F907N and I was wondering if it's possible to flash the SM-F907B (global 5G) firmware on it. Basically they have the same chip and modems so do you think that it will work?
The software updates are much slower using the Korean firmware.
Me too

I'm trying to use an S20 (G981U1) outside of US, but can't seem to do CA for LTE band 3 1800MHz (B3+B3). I'm currently stuck with LTE on that band, it seems that this version isn't capable of CA_1C for band 3. Does anyone knows if this can be activated somehow? I've seen that for the S8+ was a method to add new combos , but I'm not sure this will work for S20 and I really don't want to mess with the EFS at this moment.
Any heads up?

You might be able to flash that countries firmware to the phone.
Samsung S20 5G (US) doesn't support 4G CA combos used in EU: https://cacombos.com/device?model=SM-G981U .
And because Qualcomm version used in US, you can't flash EU-version firmware because in EU networks use Exynos.

Don't know - free to test but I recommend global variant for Indian market not HK.
Hi everyone,
I got a S20 Ultra (Korean version) as it was one of the few with Snapdragon to work on UK bands but I am struggling to trick the phone to show me content in english on native apps (Samsung Daily, Weather, Members app...).
Don't get me wrong, the initial content is in english but once you try and get more info, about the weather for example, it takes me to a korean website. Members is in Korean all around and daily has Korean cards inside.
Which I think is normal due to the Korean CSC.
I changed the CSC from SKT to KOO but it only removed the network branding and default carrier apps.
Is there a way to bypass the CSC or install an English CSC from UK for example?
did you find how to change it ?
Also have the same issue. I am in Australia. I was thinking about installing australian firmware?
I have an SM-G9860, which is the Hong Kong S20+, and live in Romania. Anyway, I'm pretty much in the same boat as you, having the TGY csc instead of ROM or ORO. Samsung Weather sends me to samsung internet to accuweather.com, which is just what my old exynos s10+ would do, and samsung daily seems about normal, with only the spotify recommendations card showing something in chinese. On the other hand, Samsung Members, which had been acting like I was living in Hong Kong (showing me the offers from there and so on), has, since a few days ago, started showing me content from Romania. Upon randomly launching it last week, it gave me a message as such: "App might reset due to regional settings change" or something like that. My csc is still TGY and samsung pay for instance still is the hk variant. Other than that everything is pretty normal.
Thats why I was asking if its possible to dowbload firmware for the Australian version of the S20 Ultra which is not snapdragon (the reason I bought Korean version because it is snapdragon). Will things still function as normal if I put on Australian firmware that is designed for a korean phone? Sammobile has the firmware for all countries spec phones.

No. Quite simply put: You can only flash Firmware intended for that specific handset.
For example: I own the SM-G9880, which is the (snapdragon 865) Asian version of the S20 Ultra 5G.
I can only flash three firmwares: TGY (Hongkong), BRI (Taiwan) and CHC (China "open"). NO other firmware. Certainly not, say, the EU Firmware, which is for another CPU entirely (Exynos 990)

Thanks Roman. For example I cant use Samsung Pay because it says 'cards must be from Korea'. And a few other things of that nature.
Firmware of a US s20 Ultra running Snapdragon chipset wouldn't work either?

The same way I can't use it because I'd need a card from Hong Kong, but I just use GPay instead, works like a charm. Nope, nothing, I'm afraid. You can only flash the Firmware intended for that specific model number. I am in a slightly different conundrum - I got the SM-G9880, and I'm using it in Europe. While LTE and 5G bands are similar, they aren't identical. LTE, it's barely noticeable, since 1,3,7 and multiple others are supported, 1,3 and 7 work in 4x4 MIMO and the most important Carrier Aggregation Combos like 7-3-3-1 (12) work too. Only thing I don't have is CA with Band 20 (only supported in single mode) and on the LTE side that's basically it - I even have 28-7-3-1. However, 5G wise, different story. Only Bands I got for the EU are N1 and N78, which luckily is exactly what my carrier uses, but there might be N3 and N28 down the road like in other EU countries so it'd be nice to have that...

like i can see carriers/KTC and only Korea ...
i just don't know how to modify the file like how to unpack and repack so i can flash it i search for a guide but nothing on google or here in XDA
Is it possible to flash F926B firmware on F926U device? I checked their specs and both have same 888 chipset, only different I see is radio SAR rate (international being higher).
Is it possible to flash international firmware on US variant?

No its not because the F926U has got mmWave Antennas and slightly different software for the mmWave Antennas, while the F926B does not have mmWave Antennas.

No absolutely not. It won't flash. And if you manged to, you'd end up with a brick. Two different devices with different hardware.
Us and Europa work on different freq
Is anyone using a Korean or Chinese s20 in the US? If so, what carrier are you using, and do you have any issues? I know 5g probably won't work, but other than that, any problems with service on these phones?
To answer my own question, the s20 Ultra Korean model (S988N) with KOO csc works perfectly in the US on Verizon and Tmobile, including 5G.
I live in India. I have a HK Variant of the Samsung Galaxy S22 (9010).
Airtel just launched its 5G in 8 cities. I checked NetMonster, and the tower near me is 5G enabled.
However, it appears for 5G to work on Samsung phones, an OTA update is required.
Since I don't have an Indian variant, I won't receive this Airtel specific OTA (which appears to have been pushed for Indian Galaxy S22s).
Apart from changing my CSC thru Chimera Tool etc, is there anything I can do? Please help.
You could contact your service provider

I too have the same variant. Samsung Galaxy S22 (9010) -- Taiwan BRI version.
Same issue.
Maybe once the Android 13 stable is rolled out to our devices, it may work then.

I wonder if there are enough number of us out there for Airtel & Samsung to consider fixing this issue.
Requiring an OTA to just connect to a band seems too much of a hoop to jump to, especially if people are visiting from overseas and have compatible bands. I'm hoping you're correct about the stable Android 13 update, let's see how they approach this.
I have heard S22 series doesn't need an OTA 5G update to work with 5G network. It's enabled already. The OTA is only for the mid range and previous gen S series. Due to some 5G bands and implementation. There are some people with S22 series device in Chennai receiving 5G signal without any issues.
