Thinking about flashing factory firmware

[Faceplant15]

Hi all,
Looking for advice. I'm thinking about flashing factory FW on my note 20 ultra vs carrier firmware. I started thinking about doing it when I tried to use the Samsung Smart Call feature and found it was replaced by my carrier. I also have not been able to find a free visual voicemail app either, I tried to side load Samsungs but it didn't work, wondering if it was because of the US Cellular modded firmware. If I load factory FW will I have any trouble with connecting to US Cellular for phone and txt?

Good thing is you can go back and forth between unlocked firmware and carrier

My phone is still locked by US Cellular. Not sure if I can even flash factory FW on a locked phone.

You can but it won't be Sim unlocked until you do that on the current firmware

Its worth asking, my primary reason to replace the US Cellular firmware with stock samsung firmware is to restore the dialer, and the ability to use Samsung Smart Call and hopefully Samsungs visual voice mail. Will loading stock firmware scrub the US Cellular dialer and misc. bloatware?

Unlocked firmware can takeaway certain carrier features , thats something you have to experiment with by flashing the unlock

I'm doing more research on potential pitfalls I may run into when flashing my note 20 ultra 5g. I'm on US Cellular, not sure if my phone is carrier locked or not. I ran into this article on Itechify.com https://itechify.com/2020/11/09/install-stock-firmware-on-note-20-or-note-20-ultra/?amp
It has the following warning. Looking for firmware on sammobile site I see nothing for US Cellular specific firmware. If I do find the carrier specific firmware and am able to flash it, will it still have the US Cellular specific dialer etc in it?

Remember, downloading the appropriate firmware is very important. If your phone is carrier-free. Like it’s not branded with any carrier like T-Mobile or Verizon. You can easily download any carrier-free firmware with the origin of your country for your phone from the Sammobile. If your phone is carrier locked, you will have to download the specific firmware for that firmware. Also, some carrier-locked phones are not easy to install firmware into. The process is different for those phones.

All carrier firmware are universal, your sim should dictate what goes on it .

Highjack, but same topic. I'm using a Note 20 Ultra 5g on Verizon. There's a known issue with Note 20s losing signal, and the fix Verizon offers is to download Samsung band switcher and select 4g only.
I'm wondering if flashing a stock Samsung firmware would in any way help this. I know the Verizon Sim card will dictate the service.... Any thoughts???

You on the carrier or unlocked version with Verizon?

Carrier.

Carrier.

I don't think flashing the carrier firmware or going to unlocked will help
