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

Search This thread
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.
What's your location exactly?
Is it worth it to import one or I will miss something?
Thanks

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.

How did you do it? I am always stuck with activating phone step at first phone setup.
I remember at activation process, it showed activation not needed.

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

Hola soy de España y compré la versión 9980. ¿Esta versión es compatible en mi región? ¿Funcionará correctamente? ¿La radio fm está disponible? Gracias

Translation: Hi, I'm from Spain and I bought version 9980. Is this version compatible in my region? Will it work properly? Is fm radio available? Thanks

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

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.
