The signal isn't the problem since I'm here on the center of our town and towers are in walking distance.

I also checked the logs on netmonster but there's no 5G detected.

I tried to change my CSC using the samfw tool if I can activate the DSS but no luck it still says "NR DSS not support" maybe changing the firmware like yours VZW not just the CSC can activate it. I'll try it later.

And btw some CSC like DSH, ATT etc that I tried cannot access the service menu using *#27663368378#* but the *#73# works but not directly you need to select BAND SELECTION then press the BACK (on the 3 dots) 4 times to access the main menu. Edit your post and add the *#73#.

Here's a video how:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
So you use my method to get the codes to work correct? Also in that monster can you click on the Little triangle next to NSA and tell me what it says when the box comes up at the bottom does it say disconnected but not restricted by carrier or does it say just say disconnected? Also in that menu you can see the list of cscs available in your phone I have like six of them but none of them is dish but I'm curious if I flash dish if I get all the bands unlocked I think I may try that next but I noticed that the LTE band stick but not the 5G bands and you can't individually select the 5G bands.

If you go back to the second or third page, there's a guy named rain something look for his username his post he's posted screenshots on his band selection screen and in his screen he had tons of 5G bands that's what I'm trying to get to and I'm going to do it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Yes your method should be made before accessing the *#73# otherwise it will show a blank menu.

I think the DSS should be enabled so I can connect to 5G because I think it is required on 5G NSA since the function of DSS based from google is "enables the parallel use of LTE and 5G in the same frequency band". NSA 5G uses LTE to work. And I cannot locked the band without enabling LTE bands since it is required on NSA 5G.

What band are you tryng to unlock?

I can't find the comment of rain.

Here's the screenshot.

I already tried downloading something if it triggers 5G but still it is not restricted.

The phone is really the problem since I already tested the 5G signal using my sim on both android and iphone with 5G capability.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jemfalor:
hv you disabled gcf whitelist
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
What is GCF whitelist I've seen it and I've disabled it but I don't know what it does? And to the guy having 5G problems what firmware are you running? And what kind of sim are you running? Like what service provider I've never heard of smart.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
I am getting 261 mm wave here in the area but the thing I don't like about the Samsung phones is that they don't stick on the 5G signal like OnePlus phones and other phones do like it constantly drops down the LTE and then when you use the data then it jumps back up to 5G I just wish it would stick on 5G all the time and I've been messing with other settings but I can't seem to find out how but I'm really really trying to figure out how to get these 5G bands enabled and that person who posted way earlier in the thread had every one of them available for selection I'm trying to figure out how that's possible and how I can get that way.

At least band 77 or 78 for sea band you know what I mean.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jemfalor:
gcf whitelist blocks hidden or disabled 5g bands when you enable them. the only way to get those bands working
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Doesn't seem to do anything if I do that afterwards and then I go to band selection and enable all bands they don't stick and they don't show up in that top list where you can enable and disable them.

Any other options or info you may have? I still really need to find out about that person earlier in the thread who had all the bands available.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Perhaps there's a way of doing it that makes them stick like enable the bands and then remove the white list or remove the whitelist enable the bands and then go to band selection I'm not sure but they're not sticking and I can go in the list and I can enable everything but disable the main ones that are that always stick and it will not connect to any 5g. And it'll just refresh the list after I go back to it showing that it's not connected to any 5G there's no 5gs left in the list when I remove all the standard ones that show up I'm kind of stuck.

I will try different ways of doing it perhaps you need to reboot after doing the NR whitelisting removal?

What about the other option in that menu should that be turned off perhaps it doesn't seem to have anything to do with NR though..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Lucky for you because you are on US and 5G there are 5G SA that doesn't need LTE signal.

I tried to flash Verizon firmware and now I can enable the DSS settings but still no 5G.

I already remove GCF whitelist, remove all prune combo. Enable 4x4 mimo. I tried everything that can be turned on but no luck.

Shows 5G sometimes but not really connected to 5G based from netmonster.

BTW *#73# works without doing your method maybe the settings sticks even after flashing new firmware or IDK maybe they open it after an update because I tried that *#73# few months ago but it shows blank.

If someone read this just use *#73# first before trying the samfw tool method.

So I therefore conclude that LTE anchor band is the only problem and I don't know if someone knows how to modify it so it can support my carrier SMART COMMUNICATIONS (Philippines).

I think this phone is configured to anchor on LTE band 41 only for 5G n41 band. (Configuration for Sprint)

I'll try some more CSC before I give up lol 😆

Here's my software info if someone wants to activate DSS.

Edit: it's not about the CSC if you want to activate DSS it's the model.

If you are on U firmware DSS settings is accessible but not on U1 (Note 20 Ultra 5G)

U can't access EFS folder but U1 can.

Edit: U1 with sprint csc can edit DSS settings

That's how you get them back I wiped mine out too and was screwed did everything but you add that file back and it'll work.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Fyi DO NOT under ANY circumstances hit the option Remove_mmawave_Card.

When you are on that screen of options be extremely careful because if you click that and I accidentally did yesterday night you will lose mm wave almost forever.

If it wasn't for the Post above where somebody actually got an engineer to help them and find the right file to re-add we would be screwed so make sure you are extremely careful messing around in there.

I did everything to rebuild the NV I went ahead and flash new firmware and everything and it could not bring back the mm wave card and that's because it's a separate modem add-on.

When you click remove mm wave card it actually deletes the file from the NV database in your phone and no matter what you do you cannot get it back. Well that was until whoever was kind enough to figure out how to fix it above but just be extremely careful because this phone almost made it in the trash yesterday night because of that issue and it was through a lot of Google searching that I found a remedy to the fix I actually talked to the author as well but he no longer has the z fold 2 , where the file came from and that's because it shares the same modem as we do the phone is based off of the same phone as the note 20 and the s20 ultra and so on so everything's the same so that's why it worked.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
I'm on you one firmware and I have it available.

I was going to tell you I thought it had to do with your firmware anyways but I'm a you firmware flashed over to you one firmware but I've had that feature available in both I think it has to do with the firmware is here in the USA and also there's only one carrier that has standalone 5G here and that's T-Mobile.

Almost all of our 5G currently is non-standalone based off an LTE anchor.

So you are incorrect on that but as time goes on other carriers will release standalone 5G but currently T-Mobile is the only carrier with standalone 5G. But for whatever reason I cannot connect to it with my OnePlus 8 even though it's provision for it but I can connect to the Tower on this phone, but it's not anything special anyways The Golden child is n41 here I usually get downloads everywhere I go at least four or 500,mbits all the way up to 800 on T-Mobile with the OnePlus 8
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
If someone read your fix there is another one if that doesn't work. I don't know if it works on other samsung device but on my Note 20 Ultra 5G here's a fix:

On the first release of note 20 ultra 5G esim is disabled try to flash oldest firmware with the same bootloader of your firmware now. The phone should have no esim after flashing.

And then flash the latest firmware available. It will reset all the settings of the modem too since they will make the esim available. That's it!

I discovered it when I messed up editing efs files and my phone shows no signal. Reviving using the backup files is no longer possible because the phone keeps disconnecting when connected to QPST tool. So this is the only fix that works. Hope it helps someone.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Man I wish I had Esim working on my s20 ultra I can actually find the SIM card manager and I can find the activation screen for the QR reader and the activation code where you manually enter the QR code for esim activation but I don't have any esim activation code so I can't try to activate or mess with it LOL

Also earlier today I flashed the dish firmware the latest one on you one and when I inserted my Verizon sim I had four extra 5G bands enabled but they were T-Mobile's 5G bands along with Verizon's 5G bands they included n41 and 71 and I forgot what the other two were it was really strange but I ended up doing a Sim swap and they disappeared not like they really mattered anyways but I'm starting to think there is no way to enable extra bands for this phone sadly.

But I'm still waiting on a response from the person who posted earlier in his thread that they had all the 5G bands available when they flash the dish CSC I also flashed the dish CSC but it didn't turn out that way for me.

But I'm curious if that person flash the dish CSC and left their phone without a SIM card that might happen.

Because I think the bands are enabled via the file that the SIM card tells it to load so it sees what carrier the SIM card is and it enables the 5G bands that that carrier uses within reason of course now if Verizon adds n78 they're not going to add it to our devices but they will add it to the s22 and the s21s I think already have n78 showing up in their band selection list it's just not on.

And sadly those of us with the s20s or any device from this era are left without support for that band.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Yes because our firmware are made for US telcos adding a band is a hardware thing.

I'm incorrect about the SA 5G since you posted a photo with SA band so I expected that you won't have a problem with the anchor LTE band.

But you are really still lucky because you're in the US and you're using the model that is made for that specific country so you have higher possibility to get what you need on that device except for the hardware part.

I gave up activating my 5G. I'm tired of setting up my apps after firmware flash lol.

The speed of LTE+ on my town is pretty good though for my personal use so I'll just wait if someone tries to mess with the Nv files to make the 5G works.

BTW if you are still on U firmware try the CSC change on the samfw tool it works without flashing if you want to test the DSH.

If you're on U1 I think there's no modem modifications after csc change using the tool but still try it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Can you tell me how you know this?

And what steps to take to make it work?

I also have a new gem I found that may help with enabling more 5g bands but I got very sick and I haven't tested it personally I'm starting to recover. Pray for me guys I've never been scared before like this.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
This is the result of removing gcf whitelist on my SM-N986U1 it unlocks some 5G bands.

https://xdaforums.com/t/guide-servi...vices-5g-low-band-on-u1.4182293/post-87304529

Here's how:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Thanks I knew how to do it thru the menu,I just wondered if there's any specific method to doing it as it doesn't unlock any extra bands for me.

Only time I had extra 5G bands was after I flashed dsh firmware but it was a combo of Verizon and T-Mobile bands after a Sim swap it reverted back.

Switching CSC via Sam app or the one I buy credits from I have both and used both but sadly after switching CSC if you have a sim card in the phone as soon it boots ot sees the CSC is wrong and reverts .

So it's a waste we cannot use any CSC not related to our Sims in our phones after Android 11 I think because we cannot stop the reboot/reset.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
I found a method about that and it really works just using an adb command

Check it here

better to disable only not Uninstall

When you dial the last * in the string above, the service mode menu will automatically show. YOU SHOULD NOT HAVE TO HIT THE CALL ICON BUTTON TO MAKE A CALL AT ANY POINT.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Use *#73# not that it doesn't works on some csc

Use native dialer not google

If doesnt work then what? And what does U1 stand for maybe i dont have u1. Does it mean ONE UI VERSION? if so im on 4.1

As I've said even u and u1 works so it doesn't matter.

If it doesn't work try to read more comments on the thread.

U1 is the unlocked firmware without bloatwares.

Hello everyone, i have a device unlocked usa U1, with XAA,XAA,XAA.

I unlocked secret codes for verizon in frp tool to use codes, but i cant activate 4g+ aggregation, maybe i have to change csc to this work?

I tried to set disable ca combo check and set to lte 4rx all enable

I have a non-USA sim card
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
What's the exact model of your device?

Set the LTE band config to default so the ca limitations will be removed.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] esemyuron:
Mine is S22 S901U1, but instructions are same

I have done set lte band config but doesnt work
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Check if the ca combo doesn't exist.

If not you successfuly removed it. If there's still no CA (LTE+) maybe there's no available CA in your location or you're far from the cellsites.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] esemyuron:
I have done all, but still dont work

I have an S20 for my region certified, in s20 all aggregation work
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Here's what I noticed on XAA they prioritize TDD bands than CA like mine.

In my place band 3 and 28 are aggregated but my phone connects to TDD band 41 most of the time.

And I don't mind this since it's faster in the morning and night but CA on early morning (1AM) is faster.

Try this check what band you're connected now using *#0011#

Mine is band 41

Then disable the band on the Band Selection menu. Then check your data indicator if it becomes 4G+ or LTE+.

Do it again on the band currently connected if still not on CA.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] esemyuron:
I enabled only 3, 7, and 20 bands which is needed, but aggregation not work they work separate
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
If you confirmed that there's a CA on your location and you've done all the setup here.

Changing CSC is the last thing you need to try. It won't reset your phone using samfw so just try it.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Can confirm this works on s20 ultra but doesn't unlock n25 but unlocks n41SA (which TMO has blocked )and unlocked all other carriers 5g bands together but no n25. Still working on that.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Nope it's the september security patch

Notify Update

I think I posted on the wrong thread this should be on the note 20 ultra section. Sorry.

Btw the thread you provided doesn't unlock any other bands like n78 on U1 note 20 ultra since removing SA permit list and setting lte band config do this results too.

It doesn't affect the NR combination too.

I need the b3+n41 combo but the firmware only supports b41+n41.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
How did you downgrade and what did you downgrade to in order to get the extra 5G bands? I was reading back and I found this post if you can enable n25 then I should be able to enable n25 on my ultra as well but I'm afraid I'm already on Android 12 so I bet the downgrade to Android 11 probably won't be possible.

I have also heard there was a beta for Android 11 that was released that did indeed unlock most of the 5G bands and they quickly remedied it with a fix but I'm sure the beta is still rolling around out there somewhere or available.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
The thread that I posted with the IMEI simulation tactic or option only unlocks the bands that are FCC verified for your phone so basically if you go ahead and do that and change that to GCF you will open up all 5G bands that are supposed to be enabled for your device not anything more not anything extra so when I'm on the T-Mobile SIM and the T-Mobile CSC I only get the T-Mobile bands available but when I go to GCF it unlocks all the 5G bands for every carrier that this phone is enabled for and since it's a US version it's the 256671-41 and so on but I seen in the earlier post that you were able to unlock in 25 and such and 25 will help me because I know T-Mobile is using n25 for their Network.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
I just warned users since there's a fix by downgrading when you messed up something on nv files. (Efs explorer)

(SM-N986U1)

Downgrading also is the only way to access the service menu before the other trick has been discovered (samfw tool).

If the android 11 beta to unlock other bands is real then they should never update the firmware with bootloader 3.

On my end I don't need to unlock other bands since n41 is the only available 5G band on my location and it is already available on my device.

The ENDC combination is my only problem that is encoded on the firmware and can't be modified.

I'm looking forward for the android 13 oneui5 if some miracle will happen lol.
