I'm not sure if they patched this or not, however, there's a good likelihood that this is not compatible with Unlocked devices =(. I was able to enable this on my T-Mobile Note 20 Ultra, however, after exchanging that for an Unlocked S21 Ultra, I can no longer enter menus through Google Phone as my screen flashes and then deletes the whole phone number as well now...

The funny thing is that depending on which carrier's SIM card you inserted, it automatically limits your phone's band support to what that carrier uses. But I really miss being able to unlock my 5G bands on my S21 as this phone gets pretty terrible 5G cell data (but it's WiFi chip is pretty darn good). Regardless, when I unlocked the 5G bands on my Note 20 Ultra, my cell data speeds over 5G went from 15MB/s max up to 150MB/s lol.

It works for CHC and TGY. Maybe others as well. We just checked only on those two yet since in Russia we are mainly use that CSCs (chinese for call recording and TGY for other stuff like Spay etc).

not to difficult to follow alright.....but i could'nt get past efs explorer......because it only recognised modem.....not phone.

any clues
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] edwardob:
how did you get it to work
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
i installed both the samsung and qualcomm driver but it made no change to me...still no 4G+ in places where i had them with Exynos version :( Tried on both TGY and BRI firmwares
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] edwardob:
i installed both also...mmmmm which bands did you install
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
All of them plus deleted the prune file to get CA but no luck...still exynos version had 4G+ almost everywhere
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] edwardob:
all from lte band calculator and leave prune file deleted

can i just delete prune file on its own...?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
yes you can
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] a43:
I don't know regarding on how to edit 5G bands unfortunately yet. Still messing with that stuff up. Looks like those aggregations I've done with QPST are not full. On elder Qualcomm modems/processors there was another file with aggregations we could edit but here in our new device there is no such a file and I don't know how to enable full aggregations yet. At least something started to come out. For those who need faster internet maybe better to downgrade to 10 Android and use engeneering menu code to unlock all bands and aggregations there for now?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
Is there a difference between available aggregations for TGY vs BRI because on S20 it was like that. On S20 TGY supported more aggregations than BRI
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kent800129:
Just check the code on my N9810 BRI

This method only works on Qualcomm versions

I use *#*#276633683782#*#* on Google phone dialer

and it brings up a service mode screen.

Press [5] RF Test and choose [2] PREF MODE SET

（or other options also works ）

It will show Please use *#2263# for mode set

Then just tap three dots on right top menu and choose back

It will bring you back to the main menu.

The above procedure worked for me on US unlocked Note 20 Ultra XAA with Tmobile SIM. None of the other codes work before with One UI 3.0 and Feb update.

There is a little additional work we need to do to get OPs service mode options, but the above instructions worked perfect.

Enable DSS did not work for me on XAA with TMobile Sim, but that is fine. Once I rebooted the phone, I see a new set of LTE and NR5G bands enabled!

Now I see Tmobile is connecting to lower bands. I was getting dismal download speeds on 5G (<10Mbps) and now it is 36Mbps when connected to lower 5G and 20Mbps in LTE.

Thanks

Help please.. I have a ATT N986U that I'm trying to change the CSC from ATT to XAA. The service code *#272*MY_IMEI# isn't working. SIM removed. Did they change the code or I can't do it?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kent800129:
If you are looking for a free method which will wipe all your data on your phone

Then try to downgrade your android version from R(11) to Q(10)

The secret code should work fine on Android Q

Or use ChangeCSC Samsung Free Tool to install the specific theme to change it.

If you want to keep all your data and settings

You can use SamKey to change CSC but it's costly.

Noob question:

Is any of this possible on the N986U devices? I have an unlocked N986U (T-mobile) and I was wondering if there were any extra bands and services I can enable and switch on before I take an international trip.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mindseye0803:
Yes, it is possible on N986U devices.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
Any advantages with the U or U1 devices in regards to being able to open up international bands if I do this? In the OP's post all the carriers/ bands listed look like they are all U.S based so I wasn't sure if it would help me in my case for future trips in Europe and Asia. I'm quite happy with my overall t-mobile network connection where I'm located here in AZ.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mindseye0803:
U & U1 devices have same hardware so same bands capabilities. U should enable always bands supported by hardware.

About if u can use them in your future trips to Europe & Asia, would depend on country, provider and their band support.

I would recommend checking U or U1 specs online and then compare them with country, provider and their band support you plan to visit.

I believe I may have either wiped out (deleted) or disabled the mmWave bands on my Note 20 Ultra because NR 260 and NR 261 are no longer on the NR5G Band Preference list.

How do I get them back?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] a43:
*#*#276633683782#*#* - [5] RF TEST - Band Selection - Sim 1 - 3 dots menu - BACK - 3 dots menu - BACK - UE SETTING MENU - SYSTEM - [3] NV REBUILD - [4] ALL mode, reboot. This will reset all the changes you've done to default and you can start experimenting from scratch.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Nastrahl:
I think the Note 20 Ultra doesn't support mmWave in the first place.

I can't find any information about it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rjohnstone:

NR 260 and 261 are supported on the Ultra.

I've tried NV REBUILD, but that hasn't brought mmWave back. I've tried factory reset, but that didn't work. I have even flashed it with firmware I downloaded from Sammobile, and that didn't work either. Samsung Band Selection doesn't work as well.

Prior to losing mmWave, I did tap on mmWave DB as I thought it would show a list of mmWave bands, but instead "deleted" appeared on the following page. Why would Samsung make that a permanent deletion?

I had taken screenshots of the speeds I was getting from AT&T's 5G+ mmWave and from Verizon's 5G UW mmWave before I lost the mmWave. As you can see, once you've experienced mmWave speeds there's no living without mmWave.

I ended up taking my Note 20 Ultra to uBreakiFix because my Note is now having network connectivity issues with LTE and cellular; there's just a circle with a line through it. uBreakiFix ran a diagnostic test, and their test didn't or couldn't find what's causing the issue. So now, Samsung, or rather Asursion, is sending me a replacement Note 20 Ultra. I'm a little worried that they'll find out I messed around with *#*#276633683782#*#*, and another thing that worries me is that Knox Warranty Void is not showing up on my Note 20 Ultra either.

Does "RPMB fuse Set" mean that Knox was tripped? I just wonder why Knox Warranty Void is not showing up. I don't want to have to end up paying $1299 for the replacement.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rjohnstone:
RPMB = Replay Protected memory Block

"Set" and "provisioned" means you can flash lower bootloader versions that the current version. Once it's "blown", you cannot go to a lower version.

FRP lock = Factory Reset Protection (Means you can't factory reset the device without your Google ID and password)

Hey, If! are you familiar with the efs file explorer...? Or QPST. I found out how to get it mmWave back working

https://ufile.io/dd6xbxej

Use this file... Save it to your phone... Remove the (.bin)... Transfer to your computer... Use efs... Go to /nv/item_files/rfnv/

Copy the file here

When you download the file it comes with (.bin)... Remove that from the name

Then save it to your computer

Once you save it to your phone using efs explorer, power down your phone and then go to the Samsung secret menu and enable all the bands like normal,

( I have a Note 20 5G N981B/DS and tried lots of ways but no luck. )

If your device is rooted then you can use other app to get into the service mode.

And for the 5G on Exynos devices, make sure your current OMC code includes your region

So you can get 5G connection while the default settings of OMC_BASED_NR_PLMN is Enable.

My SM-G991Q is still on Android 11 UI 3.1 and I can't do the tricks explained above. Is it blocked somehow?

Edit: So I might have done it:

Instead of calling the number from this post, I called *#*#276633683782#*#*. The only option you see is [5] RF Test, but when selecting that, selecting [2] Pref Mode set and then tapping the 3 dots and select Back, you will get all the options in the Service Mode main menu. Then you can select [2] UE SETTING & INFO and follow the tutorial from this post.

Summary:

Call *#*#276633683782#*#* Using Google phone

1) [5] RF TEST

2) [2] PREF MODE SET

3) 3 dots and Back

4) [2] UE SETTING & INFO and follow the rest of the steps as usual.

Is it correct that I should see this on the last step? I can't select anything, tapping the option SET LTE BAND doesn't do anything.
