Galaxy S10 5G SM-G977N - Samsung Galaxy S10 5G Questions & Answers

Hi,
I bought this off Gumtree and unbeknown to me it was not the UK version. Is there anyway to flash this onto the UK firmware and get rid of the korean apps etc? If I click a number even thought the dialer is set to system it pops up a Korean one which it then states is not supported.
Thanks

Why did you choose this model ?
I think there is a different model released for Europe? G977B if I am not wrong!, the issues you mentioned could be resolved by away or another but you will not be able to activate the 5G capability of the device!. furthermore, as far as I know, no one has proved successful flashing of other models firmware to this Korean model!.
If 5G network is not important for you, then you may be able to customize the phone to meet some of your required customisation.

When I bought it I didn't know it was not the UK model. It's only when you use it more that the differences come up.

My situation might be similar to yours!. however, I was somehow aware of the model and it's possibly shortcomings!, but I was able to modify a lot of features until it becomes almost whats I want except the ability to use 5G feature!.
BTW: Although the phone is KT oriented still you can use it and do some changes that meet your local settings. nevertheless, ultimate changes/customization could be achieved if you can root the device and install custom ROM.

Same Problem of G977N in Qatar

Dear, I have the same phone and my Vodafone Qatar 5G is not working. I am using LTE only. I know how to root and install custom firmware. Can you tell me how you attain 5G working on your korean S10 5G?
Your help will be highly appreciated.
Thanks

[Q] UAE camera in the US - Any caveats?

Bought a EK-GC110 off Amazon. Stated as "New, not refurbished" but price was more along the lines of a used / refurbished, so I was OK if it arrived refurbished (it did). However, it's a UAE "model".
Any caveats before I get too attached to it? Obviously there's no warranty regardless, but I don't want a month later to find out some feature won't work because it's a UAE model and I'm in the USA (not even sure what would be a problem, but...)
Thanks
wifi version has identical hardware worldwide.
even if someday you find a feature that doesn't work you could just flash the official rom for the US version, but I think the software is the same everywhere too.

Hey thanks for the reply. So nothing you can think of that may be 'different' - If I recall there's a few extra wifi channels that the rest of the world has that the USA doesn't - that's fine obviously, I just want to make sure there's not say frequencies this UAE version wouldn't have that the US would. Or some encryption or - I don't even know what else but if it's the same, no problem.
Thanks
I have the same camera.
Im looking to restore it back to factory after root but am not sure what firmware to use. Also, it seems i would benefit from using another regions firmware based on what you said. Is that correct?

Is the P20 Pro the same in all countries?

Hi!
So I've bought a Samsung S9 Duos recently and to be honest, although I like the phone and have been on a Samsung streak for the past few years, I'm getting seriously tired of their country dependant shenanigans. Because I live in Canada, when I buy a Global phone there's a bunch of stuff that either doesn't work or does only partially. And because the Canadian model is a SD proc, not an Exynos, it's an absolute nightmare to switch CSCs and get everything working right...
I hesitated long and hard to get a P20 pro, but the fact it wasn't available anywhere in Canada made me nervous. But my carrier (Rogers) recently announced it so, being really tired of this Samsung ****e, I'm considering returning the S9 and getting the P20 pro (even if it doesn't have a lot of stuff I like such as the headphone jack, SD card and wireless charging).
TL;DR
My question is, if I get an international (dual SIM) model of the P20 pro, is it going to be different than the Canadian one? Is there an equivalent of CSC codes with Samsung that I have to worry about, or can I assume it will be the same phone and I just need to activate it to get carrier specifics?
Thanks
I'm not an expert, but before I bought my P20 Pro, I made sure that it worked with the AT&T's network frequency bands. Each network has different bands and if the phone doesn't support the band, it won't connect.

Thanks for the input. I checked the bands for sure, and they are covered since it will be sold on my carrier soon. I guess what I meant is more the model itself, if there are variants per country or if we (Canada) are getting the same global version.
You see I come from a Samsung user's background and they have these silly country codes that dictate what you can use and where. I'm not sure it's related, but I found that even if on paper all LTE bands are covered with my S9, it still has shoddy reception compared to a Canadian S7. I could try to flash my CSC code to the phone, but a) it's complicated and risks bricking the phone and b) since the Canadian model is NOT the same as the global one, my CSC cannot be applied to this phone no matter how hard I try...

FunkyHuawei offers a rebranding tool, which changes the region of the ROM. I used it because I bought mine from a Chinese e-commerce website. I rebranded to European region.
I couldn't find anything about International or Global versions of the phone. I know they are region locked, but the rebranding tool will fix that. You can also flash a firmware from FunkHuawei or use HuRUpdater tool from TWRP custom recovery.
I have used both tools, and had 100% success.

Cool thanks, I'll see how this could help me out. I'm giving my S9 one last chance but short of that, I'll cough up another $1000 for this phone; I just don't want to end up in the same trap!

Question CSC question- Currently SIN and need to use with Tmobile or Verizon in USA

Hi all. I have the a few sm-g998b phones, rooted with magisk, and I am a bit confused about which CSC I should flash to the device (SAMKEY). I ordered the phones from Singapore and need them be more compatible with USA verizon and USA tmobile. Only using one sim per phone. Which CSC should I replace the current SIN csc with for each, and is there anything else I can do to make these phones play a bit nicer in the USA? I am currently having issues with no 5g, poor wifi calling, no updates, etc.
1. Avoid SamKEY. Do your own work.
2. Flash the HOME_CSC, or the CSC of the firmware of the carrier. HOME is usually a safer bet though.
You're going to have issues in the US until you flash the proper CSC. AFAIK, every S21U has all radios, but the CSC activates the correct one.
For the absolute safest, download the TMOB stock firm, and flash the HOME_CSC (as well as the BL, AP, etc), then put the Tmob SIM in after boot.

Tmobile or any US firmware can't be flashed on any Exynos Global device.

Why would you aquire the Exynos Global variant knowing your service provider isn't optimized for your firmware? Did you save money? If so I hope saved a lot otherwise it was a poor choice. Your best option is keeping the stock SIN Firmware, at least you'll get timely updates. You MIGHT get Wifi Calling and VoLTE enabled but forget about 5G and Carrier Aggregation.
Missed that you mentioned an Exynos variant. Yeah, you're ****ed. Exynos is not compatible with US bands, or at least aggregate banding.

Unfortunately, these phones are company. we needed root for some applications.
*don't use SAMKEY
This is a bit tricky because US is Snapdragon-based.
My best bet would be to factory reset (don't forget to backup) and flash a multi-csc Exynos ROM (OXM). This would detect the most compatible one for your US sims.
I would suggest getting the XSP for Singapore because that's the unbranded one.
Other than n71 5G band for US Cellular, I don't think you'll have much issues.

"This would detect the most compatible one for your US sims" Nope, that's incorrect, Exynos Global variants aren't able to detect the most compatible US Networks. It's apples and oranges, there is zero integration for US devices.

Thanks for correcting me. Least that's how it was for me using NZ sim on a G9980 SD variant.

The Exynos variants are Multi-CSC Devices, mainly for Europe, not for the US. The SM-G9980 isn't a Multi-CSC Device unlike some US Models, it's Dual-Sim. In Settings under Network Operators you can have the device select the "Best Network" but it isn't analyzing call features, it's only matching the network with the Active CSC (SIM Card).
Bro,
On the stock phone dialer key in
*#2263#
You will see the bands the 998b supports.
Now u need to check on the networks u plan to use in the US what bands are used. Not sure what u plan to do but these exynos phones should be able to roam into the US with voice n data services. Not blazing gigabits but one should be able to roam globally with these phones.

Question Best region?

Folks, I'm interested in getting a GW5 (not pro) with LTE.
I wish to use all features it offers while also keep OTA (SPay, BP, ECG, etc).
I know it could be tricky to change the region nowadays (CSC), so I would like to overcome on this, and buy from that region where by default everything is supported.
Which is the most supported region for GW5? With which CSC, and Product code?
Thank you!
What's the difference between SM-R915U, SM-R915F, SM-R9150?
I know: USA version, Global version, China version.
But I don't know the details:
hardware-wise? Maybe different LTE radio for USA?
software-wise? Of course different supported CSCs, anything else?
Guys I have a follow up question.
I wish to purchase the GW5 pro LTE and wish to use all features it offers while also keep OTA (SPay, BP, ECG, etc).
I can get it from the UK or UAE. I would highly appreciate your suggestions.
P.S - Did a CSC change on GW4 LTE, lost OTA and no way to go back now. The watch has warranty but would require a motherboard replacement.

Question S21 Ultra SC-52B Questions

So, I have an S21 Ultra running Android 13/OneUI 5.0, it is an international model from Japan known as the SC-52B (I think also may be referred to as SM-G998D?). The reseller on eBay listed it as "unknown carrier" but I did not expect it to come as a non-US variant, though everything does seem to work except 5G due to the correct bands being disabled. I can't find much info on SC-52B online, I know it has the Snapdragon 888 but no idea if it's any different to flash/program, or if I am just not doing what I need to do.
First, I was trying to flash USA U1 (stock) firmware to remove the bloatware but no luck, Odin gave me a "re-partition" error and some google results said this could be due to incompatible firmware. Sammobile does have firmware matching this model but they are all Android 12 and have the same carrier software I have now (Docomo). I assume I am probably out of luck on this conversion, I did read some info on changing CSC first but not sure if this will actually fix it.
Second, I am trying to unlock the correct bands for 5G operation on Verizon, and I found that Samsung Toolkit can do this as well as some ADB commands. From my understanding, this works on UI 5.0 but not 5.1 due to a patch from Samsung. I have 5.0, but I am getting the same issues as those with 5.1, and going via ADB does not bring up the hidden Service Menu either.
Lastly, is there any way to change the boot logo without root? I just want the normal Galaxy boot logo instead of this "DOCOMO" one, which I do understand would be achieved IF I could get the USA firmware loaded, I just don't want to brick it.
Just curious if anyone has any ideas or suggestions, or should I just trade this in on an S22/S23 Ultra? I only paid $300 and Samsung would offer $600 for trade-in, which is nice alternative but a $300 fully working S21U would be preferred. Seller does offer returns so I could also just look for an actual US S21U.
