Question S21 Ultra Hong Kong (G9980) can not flash CHC rom - Samsung Galaxy S21 Ultra

When I flash CHC rom via Odin. It says successful. But when I first setup the phone. It is stuck at activating phone page. I agree with all terms. When I click on Next, nothing happen. I can not go pass that stage. With TGY or BRI rom, there are no problem like this.
I want to change to CHC rom for native call recorder. I have try install TGY rom, then use Samkey to change csc to CHC. It restart but still there is no native call recorder option.
Anyone have the same issue?

Hey, i have a question for you since you own HK version.
Are you living in HK?
Does it miss any feature like Volte? Or 5g?
Anything worth noting before importing one?

I live in HK, Volte is active and 5G as well, just upgraded to that.
Samsung Pay and all is there, I don't think it's missing anything.
You can ask me if you need me to try something...
Also SD888, yay ^^
Edit:
I don't use call recording... Seems that's what's missing for OP!

I do not live in Hong Kong. I can't use Samsung pass or Samsung pay at all. It keep singing in screen for forever and get stucked there.
P/S: I have manage to enable native call recording by changing TGY (Hong Kong) csc to CHC (open China) csc but keep everything unchanged.

I live in Vietnam. At the moment, I am totally happy with my S21 Ultra HK version. I have use exynos version before. To be honest, exynos 2100 is not bad this year. But compare to snapdragon 888, it loose on every match. Especially battery and gaming, there is still a gap.

I have flashed successfully my G9880 TGY to CHC firmware. No problem.

So you don't need the full CHC firmware? Did you face any issue?
But I guess you won't get OTA updates now?

Yes, should work fine.

Thanks for your reply. But the radio doesn't works. Any advice ? Thanks so much again ☺

No s21 has radio in any region. You can download FM application from the store.

Ummmm sorry but I read that the snapdragon version had a radio fm. Is not true ? Thanks again

Does the G9980 have a 5g Network Whitelist like the Note 20 Ultra N9860 ?
Anyone been into the service menu to verify?

I have tested the 9980 in my region which is kuwait.
Dual sim works, volte works, 5g on sim 2 only, u ca not have both 5g.
Haven't tested call quality tbh and just went with the exynos that is being sold here.
Also i have some friends who reported that they lost 5g after some updates.
So you guys can check and make sure.

CHC firmware received update today that enables 5G on both SIM.
TGY/BRI should follows.

Note 8 Exynos: do you have the 5 GHz option in the advanced hotspot configuration?

I posted the same question on the S8+ forum:

My Exynos S8+ SM-G955F doesn't offer this option for selection, only 2.4 GHz.
I suspect the 5 GHz option for hotspot is only available on the Snapdragon version...

Well, your SM-N950U1 should be the Snapdragon version.
Now let's see if also the international Exynos version has the band selection option.

I'm on the Korean Exynos N950N and I have it.
Actually both the posts were useful, so now I know that this option can be available both on Snapdragon and Exynos version.
It looks like that there is no limitation in the Exynos SOC itself, it's apparently a Samsung decision to show or hide this option in the regional firmwares.
Hi guys,
Just found this old thread while searching in Google for a similar question. I have the Note 8 too, Exynos version (SM-N950F) and, as seems by the previous post, Exynos also allows to broadcast the hotspot at 5.0 GHz, so it might be a firmware limitation.
Do you know if there is any specific ROM, CSC, tweak; anything that would give me that option to use the hotspot at 5.0 GHz? I have found this post by @phatWares mentioning a quite old tool by Wanam. Can anybody confirm this still would work? I ask because I'm fully on stock on my Note, so I'd like to have some assurance before tripping Know, flashing ROM, etc.
Thanks in advance for any feedback you can provide.
I had the same question and did some research.
It seems there is a new EU directive that restricts the use of 5ghz frequencies for mobile hotspots and this is why we are running into this issue (has to do with interference with police radars and such).
Logically one way to circumvent this limitation is to change CSC to a country that does not have such limitation.
I am outside the EU and I have a EU phone with British firmware and CSC, I have yet to find a proper CSC to switch to.

Thanks for your reply aljazzair. I'm also outside of the EU and US, but I think my phone is (SM-N950F) is an international unlocked version; I don't know what that is supposed to comply to.
Are you rooted? Have you tried the tool that I've mentioned in my previous post from Wanam? It seems to be a CSC Editor that allows you to enabled the 5.0 GHz option with a checkbox.

Hi,
My phone is not rooted. Like you, I have a SM-N950F (european unlocked).
.
I did change the CSC on my phone successfully once, it was a couple of weeks ago.
.
The reason was that I was on a TUR CSC due to an OTA update whilst in Turkey with a Turkish SIM on a TIM phone which had XFE firmware.
.
I was annoyed by the resulting samsung software notifications in Turkish, which is a language I do not understand, so I wanted them gone.
.
My CSC is now BTU/BTU/TIM.
.
The procedure I used involves using odin to flash what is called a "combination rom".
The combination rom essentially replaces the stock rom with samsung software used by samsung support engineering staff for diagnosis and repair.
.
It is critical to only flash a combination ROM that is compatible with your bootloader version.
.
I had the DSG1 stock ROM with the latest bootloader when I flashed the combination ROM, so the version I used is:
.
COMBINATION_FA71_N950FXXU7ASG1_CL12991683_QB24738638_REV00_user_mid_noship.tar.md5
.
There is a seemingly cumbersome procedure to follow involving Odin, several factory resets and reflashing multiple times, and it worked flawlessly for me.
It is described here:
.
https://forum.xda-developers.com/showpost.php?p=74324845&postcount=87
.
I would re-use this procedure again without hesitation.
.
But I have yet to find a CSC code that would allow 5ghz hotspot capabilities (so non-EU) whilst retaining Samsung Pay and avoiding software notifications in a language I do not understand
.
If you know of such a CSC code, pls share
Perhaps somebody that tried that Wanam application to edit the CSC could confirm? That might be worth rooting for

Quick question, do I need only UK CSC?
E.g. If I flash a BTU firmware on an ITV phone is it going to work, or given that it is a multi CSC it will just switch to ITV when I insert the sim?
Got this new beta and the best thing about it the keyboard which seems much better at auto correct now.

I use combination firmware and Realterm to change CSC. I successfully changed CSC to BTU (England). I flashed BTU firmware. Run phone and turn on Samsung members App. Registration to BETA program pop-up on me. But when I click it and click enrol to start firmware download I get error that my SIM card is not from correct region. Even when sim card was not in phone. Only solution is to buy Sim card from England operator which I cant in my country. So I was unsuccessfull. Hope someone who has ability to download firmware will get download link a share it here with us. Thanks you very much and sorry for my bad English.
Could anyone do this who lives in the UK?

Not at all mate, thanks for trying at least. Seems an OTA is the only way to get it without the samsung members method. Hopefully someone catches it soon, itching to update.
I think we will have to wait for the second beta, so that those who could not because they formatted, can do it there
Has anyone made use of this new chat feature on the Samsung stock message app? I click on it to enable but nothing seems to happen. I don't know if it's to do with some future Google rcs chat option? Do you guys know much.

Guys,
Does Google Pay work for anyone on this beta?
For me (I'm on the Russian ROM (SER) and installed the beta unofficially, via "update.zip"). Now Google Play Store says device uncertified and Google Pay doesn't... well... pay.
Samsung Pay does though. I hate it though.

I have one of these TGY (from Hongkong) N9600 devices... It is still stuck on the Dec security patch, NOT sure if Android 10 will ever make it. All updates so far have been slow.
I use the device mainly because I need to maintain 2 different phone numbers, so the dual-sim helps. But using it on AT&T postpaid, the service sucks... NOT to hijack this thread but I can't seem to pull anything above 25MBPS or push above 2MBPS, NO matter where I am. My wife's iPhone is easily able to download at 100+MBPS. May be it is time to jump over to the dark side (?)

Odin + ROM available for Samsung S20 FE SM-G7810?

Bought an S20 FE in China. Has Google play services but had to download Google Play. Also has Chinese apps embedded like Baidu. Also random things won't work e.g. Voice wake up for Google Assistant, Netflix "not compatible with this device" in app store etc.
Would be ideal to install the standard international OS but don't want to brick the phone. Wondering if possible? Is there an Odin and ROM available?
Thanks

there are some S20 firmwares floating around on sammobile.com/firmwares but not for your specific model. The FW's have been cross compatible for the last 5 galaxy s devices so long that youre using the FW for the processor type you have. I have a 781u1, for which there isnt a FW available for downloading ATM. If its a qualcomm, you should be able to flash any other qualcomm based FW, but youll likely need patched Odin to do it so it can ignore the version errors that surely will crop up

Hello. I live in Italy and will receive the same phone in the next few days. I have already downloaded the firmware for my country, but it is for the SM-G781B version, do you think I can flash it with Odin, or I get errors. I would like to do the operation, even before doing the first start, to make everything clean! What do you recommend, based on your experience? Or do I leave it like this and use it regularly? Thanks.

According to past experience, Samsung mobile phone version of mainland China and Hongkong version of the same hardware, ROM can be universal, but before the official release of S21, no one can be sure.

The mobile phone software system of any mainland China brand is bloated and complex, so I immediately wrote it to Hongkong version ROM after receiving the goods, so I have no conditions to recommend the use of the mainland China Version System.

So it means that if I buy the s21 ultra in mainland China I can flash the HK firmware on it, if they have the same hardware, right?
Because of my foreigner ID I can't go to Hong-Kong and go back to mainland. And I don't know if it's possible to buy HK version of the s21 series from China. That's why I plan to buy the Chinese version and flash the HK version on it
According to the experience of S20 series, it is recommended that S21 should pay attention to hardware configuration and pay attention to relevant forums in Chinese mainland after listing, because no one here cares about the relationship between Hongkong and Chinese mainland ROM.
I also bought the Chines version (SM-G7810) which was flashed to Hong Kong version by Etoren store. I would like to flash to a European frimware. BUT the Chinese version has 8GB of Ram. In Europe etc it has 6GB of ram. Will that cause issues?
On a Hong Kong version I was able to flash the Chinese ROM. I did it because call-recorder is working then and essential for me.
I suppose the other way, from Chinese tot Hong Kong rom will also work.

yes, that is the same phone. (SM-G7810). But the europeans have 6gb in stead of 8gb and are SM-G781B or something.

Question 5g in UK on G9980 BRI

Hi,
I recently purchased a G9980 from Asia and received the BRI CSC version.
I've tried a 5g Giffgaff SIM in slot 1 and 2 and can't get 5g in a 5g area.
I've done a bit of research that says that there are 5g problems with the BRI version in Europe, but the listed problems seem to be mostly about 5g not being listed in the network options 2g/3g/4g/5g etc which is present in this version so not sure if changing the CSC will fix that.
Can anyone shed any light before I go down the samkey route to changing to TGY as to whether this will work?
Thanks in advance
Check this thread. The solutions may work in your country.

Changing CSC is NOT possible with Samkey for G9980. You'll have to use ODIN to flash the CSC.
On Sammobile I checked and both TGY and BRI seem to have the same CSC file lol

Oops. So what does that mean? It's been uploaded/labelled wrong? Do I need to source from elsewhere?

Although reading in the S20 forum the same thing was said about the S20 that the firmware was the same just needed to swap the CSC in samkey Here so maybe it's the same for S21 ultra? To be honest this CSC stuff is new to me so I'm probably not understanding it properly. Thanks for your help so far!

On HK variant, no need to change CSC if you just want to enable some 5G bands and make 5G work. Did you already try methods on the link I shared specially the "Remove NR Whitelisting" one?

Sorry I struggle to navigate the XDA website on mobile. The layout is not great. So I didn't see all your post but now that I have read it, it seems to be exactly what I need! I'll try it when I get home later and I can concentrate on not messing it up and can check the band's I need. I'll report back layer. Thanks again!

Hi!
It worked! Thank you so much for your help!
I didn't get the 800mbs above, only 200, but it's a good start! Cheers!

The speed depends on your location and network.
Thank you.
So do I gain anything from changing to TGY which seems to be universally recommended over BRI? Faster updates? Less bloatware? Anything else?
