Can anyone help me with the drivers please I don't know what to install them under everyone says just install the Samsung drivers well that's not working I keep getting that there's not an embedded file system in QPS t I manually install drivers from the Qualcomm diagnostics or whatever and I get the Snapdragon modem and everything to show up but it just won't connect can somebody tell me the right way to install it that guy does not work for me I keep getting that the embedded file system is not available or it's not there the same thing that other guy was talking about the problem he had he said he reinstalled the drivers with new ones and it worked well I used the newest ones and they didn't work I've uninstalled I reinstalled I'm at my wits ends I'm ready to throw this thing against the wall
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Have you tried all the suggestions in the comments here?

If you're on 5G open the port with X55 on the phone label.

Try to remove your sim or try another sim before doing this because some telcos blocked the access of efs.

What's the exact model of your phone?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Sm-g988u1

Here's the thing also isn't removing the sim pointless because when you have to insert the Sim you want to use all the settings you just changed revert back.

Sorry for sounding crazy I'm just at my wits end with this thing it's been nothing but problems I bet the stupid Sim is blocking it because it blocks everything else every damn cold is blocked too but with the OnePlus 8 if I go in there and change things and then I switch Sims then all the settings revert if I change carrier policy or anything all the settings go right back to the way they were when I change Sims.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Try all posible fix first before thinking other problems because your issue here is you can't access the efs.

There's a carrier policy file here that won't update the csc if you change sim. Try to read all thread comments most of the answers are already here.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
You talking about the device config file I seen that in my OnePlus 8 in the carrier policy area and you just change the true until false right and then the update doesn't happen does that really work?

I've been up for over 24 hours straight messing with this phone I can't do anymore I'll have to do it when I feel like it I'm just totally burnt out with this thing but I appreciate the help and I bet it's the sim blocking it because there's no other reason why it's not working

When you install the drivers do you just install the Samsung drivers on their own and it works or do you have to manually install them with the have disk option in the device manager like I did?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Actually I don't know if it works because I have no other sim to test it. Just try it.

I use the samsung driver installer I didn't install it manually like browsign the folder.

What sim are you using?

I think if someone with the same phone and sim read your comment they'll help you if they have successfully opened the efs.

And also try to browse other threads with the same model since this thread is for SM-N986xx
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
So you were right about the sin I put in an AT&t SIM and I got it to work QP St is up and running.

Could you kindly point me in the direction of the file you were talking about that doesn't change things the carrier policy they have in there since I just put a AT&t SIM in there to get it to be accessed but I would like to have a Verizon one or something similar
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
So I don't know but it seems like this phone has issues staying connected to 5G like when I reboot the phone it connects right away to nsa's connection but the longer it's on it seems to drop the connection more and just be stuck on LTE which is just weird but none of the edits I made stayed after I swap the SIM which really sucked but I seem to be able to edit everything when the AT&t card is inserted I cannot get to the band list at all but I'm able to connect with PCAT and qpst.

It also seems like with AT&t well really boost mobile that it sticks on NSA connections longer which seems pretty cool I also picked up some mm wave tonight as well with AT&t and it's stuck for a while Verizon says that this whole downtown area is ultra-wide band but yet I only picked it up for maybe two two different times for a 2 minutes each so it's just constantly dropping the connection and I don't know what's going on with Verizon but it just seems to be a constant problem no matter what phone I use.

Anyways even though the AT&t file carrier policy and everything is pretty wide open they do disable standalone bands it seems like so I'm going to re-enable those and then I'm going to play around with some of them prune files and see what happens since it seems to stick with the AT&t and I won't be having to do a Sim swap can anyone tell me what file they were talking about that you used that made the edit stick?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Sorry I just read your comment you should click the reply so I am being notified. But I know you already fix your problem because you found a way to access service menu on android 12.

I'm wrong about the carrier policy file that won't need to restart after changing sim. It doesn't work I just tested it now while testing my 5G to be activated.

And I give up now I already tried everything but still my 5G is Not Restricted. Thank you that you give me hope after you discover the samfw tool.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Hello OP @tribalfs add this on 1st page if it works on SM-N9860.

Access service mode menu on Android 12 one UI 4.1

Dial *#73# on native phone app then select BAND SELECTION, tap BACK 4X (on the 3 dots at the top right corner) to get to main menu of service mode.

Thanks to original poster

Thanks for this info, brother. Unfortunately, it does not work on SM-N9860. :(

The good thing though is that it seems that we do not anymore need to manually remove the NR whitelisting on SM-N9860.

5G now works right out-of-the-box on the latest firmware even after performing factory reset on the device .
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Wow congrats thanks for the info. So I think this method only works for U and U1 models of note 20.

I'm still struggling to activate my 5G I have a U1 model.

Tried everything but no luck!

The last thing I did is to add 5G ca combo manually with the right LTE anchor band which is band 3 on n41 5G band but still the 5G is not restricted using Smart sim.

I cannot test it on Globe since there's no 5G signal here.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jemfalor:
try removing gcf whitelisting
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Tried everything that I read on this forum.

Remove gcf whitelisting

Remove prune combos on LTE and 5G.

Enable LTE DIVERSITY CONTROL TO 4RX

Enable DSS.

Etc.

I'm suspecting that it is the settings for LTE anchor band. I think it is on one of the file on the rfnw folder just like the 0028874 file that contains LTE ca combo of LTE phones.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
I confirmed that the anchor band is really the problem by getting the ue capability logs.

Deleting cap_prune file or editing it manually to support the supported combo of 5G and LTE band (anchor band) doesn't affect on what the modem is configured.

The combination is still LTE anchor band 41 on n41 5G band (Sprint US CONFIGURED) based from logs.

Smart PH uses LTE anchor band 3 on n41 5G.

CSC change to non US telco isn't possible for u and u1 model.

00028874 file on rfnv folder contains the ca combo of LTE phones.

Maybe one of the files on that folder hold the ca combo of 5G too?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
Globe also uses band 3 and nr41 at least in my place
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Are you on U1? Or 0?

Smart also use band 1 anchor on some locations.

Edit: oh sorry you're the OP so you're on 0.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Did you figure out how to get your mm wave back? I accidentally deleted mine and somebody posted a file fix but you have to get to EFS explorer through qpst in order to install it and you'll have mm wave back do you still have the phone? If so I'll post the file and how to for you.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
Where is this file located that you're talking about above I didn't know you could edit the anchor bands and such I would definitely like to play around with that.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
It's just what I thought but sadly the anchor band settings are encoded on the firmware and cannot be modified so modifying it isn't possible for now I guess?

I'm waiting for the android 13 update maybe they will remove the anchor band limitation since s22 has no anchor band limitation on XAA CSC based from what I have read on the comment section.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] intheb0x:
I see. I hope it's coming soon!

They claim the beta is coming sooner than later!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
The note 20 ultra 5G puerto rico CSC are now on bootloader 3 so maybe the upcoming updates on all CSC will update the bootloader too.

If you're still testing something don't update the upcoming september security update if you still want to downgrade to A11.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ejoya:
same problem as my fold 3 us u1 model. I can get n78 on some spots in the ph (mainly malls, makati and bgc area) n41 CA does not work even if all tweaks have been made. It seems the anchor band is hardcoded. On my flip 4 US model, I can get 5g easily with the same settings without problems.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
Try this one. He change it to VZW CSC

https://xdaforums.com/t/how-to-enab...luding-sub-6-and-mmwave.4488435/post-87414309

And it's just softcoded on the firmware not hardcoded so it can be fixed by an update if they want too. I'll wait for the android 13 update.

Edit: don't try this if you're on note 20 ultra 5G it removes the esim subscription
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Romeo Nickolas:
I'm now on android 13 oneui 5 and still the 5G is not restricted. I think they did nothing on the modem settings or carrier config just the UI update.

So it's confirmed. This US varriant of note 20 ultra will never be support the 5G here in the PH.

Does the QPST method still works on Android 13 OneUI 5.0?

I tried the *#73# service menu to activate the bands on Flip 3 (F711U1). Was able to unlock few bands. The ones that are used in my country are 28, 78, 258. 78 is now there but not other two. Not sure if the 258 is even supported by this model or not. However 28 is supported and is present in the international version.

Can anyone help me or guide in unlocking the 28 band or possible make LTE+ work?

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kent800129:
On One UI 5.0 can use Samsung Toolkit on Google Play store follow the instruction to get into Service Mode.

But the shell exploit was blocked by Samsung After OneUI 5.1 .

So if you're still in the bootloader which can downgrade back to OneUI 5.0

Probably try Samsung Toolkit to see if you can use the settings in this thread.

I have a Galaxy Note 20 USA model (SM-G981U, technically not a Note 20 Ultra but the chipset is the same) that I'm trying to remove the CA prune files from, however whenever I try to open it in QPST EFS explorer, it hangs for a few seconds, then says the phone doesn't support an embedded file system. If I dismiss the message, it hangs for a few more seconds, then says the phone "probably doesn't support this file subsystem" and shows nothing in the window. The phone is on Android 11, One UI 3.1 (I tried Android 12 but it didn't work either), I have installed the latest USB drivers from Samsung's website, and I have installed QPST 2.7.496. How can I fix this?

Off topic, but I also have a HK variant Note 9 (SM-N9600), and I tried to remove the prune files from it as well, however after deleting them from EFS explorer (EFS explorer has no trouble recognizing and loading the Note 9), the Note 9's network connectivity will become extremely unstable and keep flashing between "emergency calls only" and the no signal cross "no network connection". On the rare event that it does connect, it will aggregate the proper bands, but after a few seconds it disconnects again. Is there some other config file I need to modify to get that phone to work?

Check again if 3 and 28 already show.

Same. I also have the same model but missing some bands. Maybe I should switch back to TGY from BRI to check?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] xUtsumi:

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] xUtsumi:
Update. The bands disappear when you update to the latest software when in TYG mode. Same with BRI mode.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
Somehow all the bands are present for me on BRI ROM but 5G is still not working im in a location where 5G should be on Band 1 (2100) but all im getting is 4G, also 4G+ is rarely seen....with exynos i had 4G+ everywhere.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] xUtsumi:
I've talked with the OP and shared that I was able to make 5G work with the CHC rom then switched CSC to WWD. Now WWD has the same bands as TYG. Maybe there's something other than the bands to make 5G work on our devices. I also have a locally sourced S21 Ultra that I tested here in my area and the 5G is strong. Apparently it's connecting to the 78 band which is weird cause OP said that 78 is reserved for modems and such of Globe. I have to experiment more on this and will share with you guys what I find. :)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jirka607:
Here the situation is quite more complicated because my provider is using some kind of whitelist to be able to connect to 5G.

Btw with S20 series from HK there was difference in available CA combos between TGY and BRI do you think it can be a case for Note 20U also? Because really strange is that i can get 4G+ but only on few spots so it seems like some combo is missing because my provider has 4G+ this way 800, 1 800 and 2 100 MHz

I just saw a method for opening the menu again for Android 11. I saw this on the US thread. :)

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.

I can finally go to UE settings with this.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kent800129:
Hi there,

If you want to activate the n3 n28 bands on BRI

Please go to [2] UE Settings >> [2]System

On the last page choose [1] SET LTE BAND CONFIG

Then click on [1] SET DEFAULT LTE BAND

Reboot your phone and check again the available NR bands.

Hi there! Glad I saw this thread. I actually don't have N20U but S20FE, with more or less same limbo. My 5G isn't working and I also have TGY FW installed. I still haven't tried to change CSC to BRI and see if it will make any difference. My office issued me a work phone, which luckily is a Samsung A42 5G and then and there I was able to confirm that my house has 5G signal (thank God yay). Now my question is - has 5G worked on BRI or this is like a matter of needing more research? I wanted to make use of 5G while my neighbors still don't have a capable phone so I can hog all the bandwidth lol
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kent800129:
As I know, the TGY S20 FE doesn't have BRI in the firmware, so you only can change to CHC (China) via flashing firmware by Odin.

SM-G7810 TGY CHC

SM-G781B BRI is in OXM CSC.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Andromeduh:
Would you know the supported bands for CHC? Or would it cause much issues if I change it to that CSC?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] khalidkls:
Can any one upload just CSC of CHC china from the extracted firware either android 10 or 11
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kent800129:
As I know, the S20 FE G7810 hardware supports:

5G: n1/n3/n41/n78/n79

4G: LTE Band 1/3/4/5/7/8/12/17/20/34/38/39/40/41

3G: Band 1/2/5/8 / GSM: 850/900/1800/1900 MHz

It's wired that it doesn't support B28.

So if you're in EU that needs B28 on your carrier, you may find out the 4G speed is lower than what you expect.
