Please a little help! Note 10+ 5g sm-n976n

Hello and awesome Easter everyone!
I live in Norway and used to have an Asus ROG Phone II until last week, I swapped it with a Note 10+ 5g Korean edition.
The phone is working nice and it is A LOT BETTER than the ROG, that phone is a powerhouse, but the software, not so much...
With this phone I have a few problems:
•Lots of stuff in Korean
•Cannot save home numbers with country code or the contact name won't show when anyone calls or text.
•Norwegian language not fully supported.
Everything else works flawlessly and I love the phone so I wonder if there is anyway I can fix this, even if I have to root, it's not a problem. Been thinking if I could flash firmware from the 975f as it 8s the same soc.
Will be very appreciated if someone could help me with this!
Have no problems with flashing and rooting, just don't do it for a long time. Thanks in advance!

Is it carrier branded? If so, try flashing the KOO csc firmware, that may help with some of your issues.
You can't flash the N975F firmware, as it's not meant for the 5G variant.
The N976B model is the 5G variant, but it also cannot be flashed to the N976N.

I have KOO installed now and i have all the "problems". I know the 976b have snapdragon 5g modem and i have exynos. Oh well gonna have to live with it! Thanks for the help!

SM-N976B is Exynos.
Edit: just curious, have you been able to get it working with 5G?

my sim is not 5g nor we have 5g in my area yet unfortunately

Same situation

You can use PD MDM package blocker to kill the bloatware at boot up. Useful to have.

Thanks it's work =)) not exactly what i wanted to but it's fine . I disabled all the korean blootware :good:

If you open a individual app in PD, in the upper left corner is a box. If you check it the PD MDM widget will toggle any checked app on or off.
If will clear data in apks better than doing it in Settings can; presumably PD leaves no nulls.
If you ever get the flashing screen warning thing *oh no* you need to deactivate PD MDM as system administrator.
PD runs in safe mode! It's been very stable and haven't seen this happen in years.

flash koo firmwere download through sammobile

I have bought SM-N976N but the seller had flashed SM-N975F firmware in it. I have now flashed it with KOO version of SM-N976N but my problem is that the phone is not recognizing sims or carrier in it (not even 3G or 4G) Ping test is always failing. BTW I am from Pakistan.
So my question is , Can I flash OXM version of SM-N976B cz my region will be covered in it. Because samsung has not launched a PAK version of firmware of SM-N976N.
Please help how will I be able to get my sims working in Pakistan with or without root? Please help anyone.

Flashing S20+ SM-G9860

I recently obtained a Samsung S20+ SM-G9860. However, I am in the US and am intending to flash the AT&T firmware for the SM-G986U. When I try to do this, I get a secure check fail on the PIT file due to the differing model. Is there a way to circumvent this? The two models have identical hardware from what I can see.
Is it possible to do this, and what is the process for doing this if it is indeed possible?

You cannot flash a rom built for a snapdragon chipset on a phone with a exynos chipset
Be thankful there is that safety check built in. Lol

It's not Exynos, it's also a Snapdragon.

Oh, the Brazil variant. Still dont think it will work. They might be dual sim

It's the Hong Kong variant. It does appear to be a dual SIM, however.

YES PLEASE!! I need to change my S20+ Snapdragon SM-G986U firmware to SM-9860 too!!!

The hardware isn't identical, SM-G986U is a Single SIM Device, your's is a Dual SIM.. TGY is the CSC in your device and even if you could flash SM-G986U Firmware the CSC would not change, it will still be TGY. If you're looking to get full AT&T call functionality on your device it's not possible as the CSC doesn't support AT&T compatibility. Firmware is CSC specific as well.

But mine has two IMEI numbers though 1 for physical and another for esim, HOWEVER the esim option to add another QR code for another network is not visible. Its like the device is locked for VERIZON esim use only.
Oh well, guess gotta wait for another few month for newer updates to be able to use another network esim or firmware flashing that can enable this option soon...

If your device is the SM-G986U it's a Single SIM Device which doesn't at this point doesn't support eSim. Does the SIM Management Screen actually display the word "eSim"? Share a photo please. The device is likely still locked by Verizon. What is your motivation to change the Firmware to SM-G9860, do you live in Hong Kong?

Im sorry unfortunately I cant post links for my screenshots or upload any pictures..

I bought my phone online.. When I start up my phone it says Verizon, but its unlocked though because I can use any country physical simcard. Like right now im using my local simcard in Malaysia. I live in Malaysia and the reason I want to flash rom my SM-G986U device to Hong Kong firmware is so that I can use any eSim network in my country for my other network phone number.... If its a software for eSim that I can get for firmware that will be very helpful. Because the main local Malaysian samsung s20+ 5G firmware model is base on Exynos 990 which I doubt will fit for my US phone model..

I don't think you can flash SM-9860 Firmware onto your device but even if you could you still won't have eSim capability. Mix and matching firmware typically has more success on Exynos International Variants since they are Multi-CSC Enabled Devices. So if you have a British CSC (VOD) you may have success flashing German Firmware (VD2) since both CSC's are already stored in the device however even then some call features may not work. Snapdragon Devices don't have Multi-CSC's and as mentioned previously the Firmware is CSC Specific, they're made for one another. IF you had an Unlocked Bootloader, which you don't, there may be a method to modify the CSC once you root the device.. I did follow a thread a couple of years back where a gal had some success modifying her CSC on a Snapdragon Device but I believe that was a Galaxy S8. Also, I'm still curious if the word "eSim" actually appears in the SIM Management Screen on your device.

Damn.. that is some nice insights.. I read a thread somewhere too that US SM-G986U cannot and will not be able to enable its OEM or unlocked bootloader.. the eSim actually doesnt appear in the Sim Management Screen on my device. I really want to upload some links of the screenshot but for now I cant do anything as Im a new member.. I just have to wait for the network shop to open up to change my current esim card to physical simcard.. its been 2 months plus of this coronavirus lockdown and our network providers cant do much about it too..
Anyways I really appreciate the insights, like you said even if I could flash in Hong Kong SM-9860 in to my US SM-G986U, I might run into some software or calls dysfunctionalities..

Anyone got th atct update for the sm-g9880 yet? Seems the u.s has got this update before Asia?

S20+ CSC Change

Hello Everyone,
I have the SM-G985F/DS in Canada. The current CSC is XSP/XSP,XSP/XSP.
This phone is the international variant. Can someone please guide me on how I can change the CSC? I am a total noob. I would like Samsung Pay/ VoLTE to work. Preferably Fido CSC or Unlocked Canada, some bands aren't working properly.
If this isn't possible will I get updates for my phone?
This has been a big headache.
The phone is Exynos and I'm in a Snapdragon country.
Thanks

Since you're using an Exynos phone in a country where they officially sell the Snapdragon variant, you won't be able to flash the Canadian CSCs since they're only available for the Canadian variant.
VoLTE should work after you insert your SIM and reboot the phone, I've seen multiple reports of VoLTE no longer requiring the correct CSC to function.
Messing with band support is almost impossible on Exynos variants and I believe Samsung Pay requires the correct CSC to work so you're out of luck there.
All this aside, you will still get OTA updates based on when they're released for the XSP CSC.

eSim on Galaxy S20 5G, SM - G 9810.

I recently got the Galaxy S20 5G, SM - G 9810.
The menu item "eSim" is missing in the SIM card management for the mobile phone.
Thought all S20 can also eSim?
Does anyone have any idea how to get the menu displayed?
Maybe with a different firmware? There is firmware from China on it.
Wanted to run an eSim, SD card and another real Sim in the cell phone.

You have the S20 Hong Kong Variant. eSim isn't available on your device and changing firmware from TGY, which is the CSC on your device, to a different CSC usually creates more problems than it solves. The Forum is littered with users who have numerous issues after changing firmware. Firmware is CSC specific so altering this compatibility can have adverse effects. Carrier Aggeration, Wifi Calling, Samsung Pay, Samsung Health, Secure Folder as well as your Warranty may be at risk.
Another option if you want to have Dual SIM and SD Card is adding an adapter. I wouldn't consider that since it's a pretty funky setup.
https://www.simore.com/en/dual-sim-adapter-galaxy-s20-ultra-samsung-speed-zx-twin.html
On my Galaxy S8 I shaved a SIM Card, fixed it to the back of my SD Card to facilitate the setup you're hoping to achieve however Samsung squashed that option on S9's and likely S10's and S20's. I'm curious why you feel eSim is vital? It's much easier just to swap out the SD Card with a SIM when Dual SIM is beneficial.

Which S20 Snapdragon variant can support Nano Sim + eSim + Micro SD? I thought the HK version could do that and was about to buy.

According to Samsung Support, which I would take with a grain of salt, a future update may enable eSim on Snapdragon Devices. The Snapdragon 855 SOC is compatible with eSim as evidenced on the Galaxy Fold and I would think the 865 SOC on the S20's is as well, however at this time I'm not aware of any eSim enabled S20's with Snapdragon SOC's.

Question: Convert US unlocked to EU unlocked

Hello flashers.
Question here.
I have a US unlocked version G781U1/DS. Is it possible to convert to G781B/DS? The reason for this is European B version has dual sim support, whereas apparently it is disabled on US models. Otherwise why would Samsung put DS into model name for U1 and snap in a dual sim tray?
I think both devices have same hardware specs.
Will it work?
Thanks.

No, it will not.

Why would you want to do this? The U1 version is a multi-CSC firmware and should work as needed in any country. I have not been able to secure a FW set for the S20 FE5G as of yet, but if it was available, it could be confirmed or denied that the specific CSC you need is contained within. Again, I'm rather curious about the issue you're facing to lead you to want to do this. Technically, you should be able to flash any Snapdragon CSC that is built for the same device. That is speculative as ive not confirmed this, but that is how it has been historically from the S8 onward

I have tried all CSC versions available in CSC menu, none of them enables dual sim. Note CSC available are most for US carriers like TMB and ATT. There is XAA (international apparently) available as well but does not enable dual sim either.
