No sir. Never sensitive. I know better than to never stress anyone or anything especially on any forms of social media. I'm all for helping each other out and yes unfortunately threads like this have to come out. I, too have been around for awhile. And have worked with many good Devs. There's one thing i can say. If something disappears or get patched. It always comes back. They always forget to patch things again. There's just too much they think about when they release a phone and there's too much code to decipher. I'll give you an example....there was an EDL script used awhile ago. That could send your phone in EDL mode. Now that got patched awhile ago. And guess what...it works now. And all you have to use is a regular USB cable. No EDL cable. There's also one more thing thats part of it but i won't disclose that. It's that EDL script that they forgot to patch. To get a Samsung device into EDL with a regular cable...a script and the other thing is very big. It shows that they they're not perfect at all and that it's only a matter of time before they once again forget to patch something big.
[Samsung Galaxy S22 Ultra] wr3cckl3ss1:
I'll take back, the thing about respect. You comment came off as disrespectful. But that could if just been me, reading it completely wrong.
[Samsung Galaxy S22 Ultra] peacey8:
This method has been the same one since the S20 and before and is posted here on these forums in multiple threads for many years now.

Samsung isn't stupid, they already know about this method and decided not to do anything about it. When they decide to do something about it, that will change, and it will have nothing to do with this thread. Don't give me too much credit.
[Samsung Galaxy S22 Ultra] peacey8:
It looks like it's all enabled correctly to me. If you're not getting 5G, not sure what else we can do... It might be 5G coverage in your area, have you tried to go to other areas in the city?

Can you also try Step 2 to enable DSS & CDRX, and also try Step 3 to enable SA & NRDC? Try those then restart the phone to see what happens.

Is there any way you can confirm you can connect to 5G in this area by using a local phone? And even better if you can see what bands it's working on.
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Are on PH now? Can you do it now for me. I have to confirm something. Thank you!

And last thing in band selection what CSC shows on the menu?

Note20 ultra.

Tried this

Using SamFW FRP tool, go to MTP tab and click on "Enable Secret Code for Verizon". See the picture below. Note it works on any US CSC even though it says "for Verizon".

If in the program output you see it's getting stuck on "Waiting for DIAG", then dial *#0808# on your phone to open USB settings and select "DM + MODEM + ADB" then press OK. The program should then complete the step and then get stuck on "Disabling DIAG". When it does, using the *#0808# menu again, select "MTP + ADB" this time and press OK. Now the program should complete the step and say that secret codes was unlocked.

When I dial *# info nothing happens. On default call and google call app. Nothing happens. I dl'd samsung driver and when going to install says driver already installed.
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
We have the same phone but it works for me with VZW CSC or even XAA using both U and U1 firmware.

If you have a spare sim on other network try to insert it first then try it again.
[Samsung Galaxy S22 Ultra] killahax6:
Im on stock unlocked phone. This doesnt matter correct.
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Yes it should work since its a US firmware.
[Samsung Galaxy S22 Ultra] killahax6:
Why would i need another sim card for it to work? I cant just get one for no reason.
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Some CSC blocked the access of some codes.
[Samsung Galaxy S22 Ultra] killahax6:
I have old tmobile sim but not active. I switched to verizon.
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Expired or not it will change the csc no matter what.
[Samsung Galaxy S22 Ultra] wr3cckl3ss1:
The SamFw app can change CSC to anything that's available inside your firmware. If your CSC firmware is US based, you're only allowed to use US based CSCs. You can't change to XXV....INS because the firmware doesn't have it. The current SamFW app is compatible with Sept firmware and all betas of OneUI 5. Samsung has not patched that ability as of yet.
[Samsung Galaxy S22 Ultra] lolDayus:
Hey so I have an S20+5G (Verizon) and yes it's not a 22 series but a lot of the steps so far have given me similar results, and I'm just trying to get back to the hidden Band Selection screen that seems to be available to most recent Samsung phones. Up until I updated a certain app manager app a couple days ago, I could access this menu and lock on to the single band that provides me with decent internet where I live. Well, said app manager has run into some issues and that's no longer an option for now (I have an S9 that isn't my daily driver that I haven't updated that app on that can still get to the menu of course).

Anyways, I've been trying all the different methods mentioned, downloaded Samfw's little program thing and got the "You can access VZW hidden menu now" message and everything. Everything looks good until I get to the Service Mode menu *#27663368378# but my screen then looks like this:

View attachment 5714121

I've tried doing the hamburger menu > Back 3 times as well as pretty much all the other options, but it seems like I've hit a wall here because nothing actually shows up on the page. Can I go anywhere from here or maybe I made some error along the way? I can also get to the Testing Menu *#*#4636#*#* if that makes any difference
[Samsung Galaxy S22 Ultra] dubblecup:
In my selection it's Sim1 XAA

and Sim 2 TMB. Unfortunately whenever I click on Sim 1 the LTE options still don't have B17 included. If I click on the menu option and click "back" and then click on LTE the result is the picture displayed.
[Samsung Galaxy S22 Ultra] dubblecup:
I know when I had the s10+ I had the option of adding the B17. Can't seem to find the option anymore.
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Sorry but I'm asking from different user.

As far as I know after setting the LTE BAND CONFIG to default from the menu it will unlock all the available bands that hardware is configured so if the band you want still doesn't show hardware doesn't support it.
[Samsung Galaxy S22 Ultra] peacey8:
From your screenshot it looks like B17 is enabled. I can see 17 in the LTE list. Have you checked if your phone is connecting to B17 with an app like LTE Discovery?
[Samsung Galaxy S22 Ultra] peacey8:
Sorry I don't have the S20, but I'll try to help.

If you use *#27663368378#, it should directly take you to service mode main menu and you shouldn't have to use the three dots -> back here. If you restart your phone, is this menu still blank?

Second, if that code doesn't work, have you tried the code *#73# to get into RF Test mode and then click Band Selection? Or does that code not work either?
[Samsung Galaxy S22 Ultra] lolDayus:
Thanks, I know it's not exactly the same phone but the narrow subject matter is more similar here than anywhere else. Yeah both of those codes take me to that exact screen, I just mentioned the Back thing because I saw it in another post. So I just have what the three dot menu shows when I click it once because otherwise everything else is blank lol.

One thing that may be unique that I've seen a couple times elsewhere is that the Testing menu below is only accessible from the Google Dialer specifically, as opposed to using the native dialer for the ServiceMode menu (which doesn't work with the Google Dialer). Appropriately, the key code for this has the extra *# symbols associated with the Google Dialer -- *#*#4636#*#*.

The "phone information" option seems the most relevant and it takes me to the much more analytical "Phone Info" screen, but the only thing that seems to be helpful in any way on this screen is being able to switch to "LTE only" Preferred Network Type. When I hit the 3 dot menu here, there's several options including "Select Radio Band" which would seem to be the most helpful, but when I go there I only have the options of "Automatic" "United States" and "Cellular 800", not the actual numerical LTE bands. Am I overlooking something maybe on the Phone Info screen? Or is the Select Radio Band supposed to give me some other options?

I get stuck on this step. It doesnt go past this part. When i hit ok it still on waiting on diag...

*#0808# on your phone to open USB settings and select "DM + MODEM + ADB" then press OK. The program should then complete the step and
[Samsung Galaxy S22 Ultra] dubblecup:
No wasn't aware of that app. Will check and report back.
[Samsung Galaxy S22 Ultra] dubblecup:
Yes
[Samsung Galaxy S22 Ultra] peacey8:
Yes what?
[Samsung Galaxy S22 Ultra] dubblecup:
Yes to a previous question you asked. So basically this isn't saying these are the channels I have enabled now or?
[Samsung Galaxy S22 Ultra] peacey8:
Did you install Samsung USB Drivers?
[Samsung Galaxy S22 Ultra] peacey8:
That screen shows the bands that are enabled on your phone. Since 17 is listed under the LTE list, that means band 17 is enabled.
[Samsung Galaxy S22 Ultra] peacey8:
Sorry, I'm not sure. The screen shouldn't be blank. It's supposed to have a bunch of options to press. The only suggestion I have is try to flash XAA firmware first, and then try the codes again from the Stock Samsung dialer (not Google dialer).
[Samsung Galaxy S22 Ultra] dubblecup:
Ok cool. Thanks.
[Samsung Galaxy S22 Ultra] phormskaran:
Hi thanks to your method i have attached a Screenshot of the Speeds with Connecting the new Built 5G Tower from German Telekom at the Octoberfest here in Munich, Germany I’m really Speechless and Thankful to you :)
[Samsung Galaxy S22 Ultra] SyCoREAPER:
This sort of worked for me using SamFw FRP.

*#73# worked after but not the longer code. I did find that after selecting a SIM, (at least for me) if I kept hitting back in the three dots in the upper corner it eventually took me to the same menu as the long code.

- S22 Ultra Unlocked on Carrier (U) firmware

Edit: If anyone is wondering why I did all that if I had an unlocked version anyway, T-Mo CSC has specific coding to differentiate in the notification bar what subset of signal you're on. For example 5G, 5G UC, 5G UWB (though it's broken in the beta on eSIM)
[Samsung Galaxy S22 Ultra] peacey8:
Very happy to hear it worked for you! I love to see those sexy speed tests!

Is that 5G NSA or SA, and is it 3500MHz or mmWave?
[Samsung Galaxy S22 Ultra] peacey8:
Happy to see it worked for you. The longer code doesn't work on all CSCs, but btw, the *#73# code and three dots -> back instructions to get to service mode main menu are in the OP. Though, I'm glad you figured it out nonetheless!
[Samsung Galaxy S22 Ultra] SyCoREAPER:
I'll be honest, I rarely RTFM
[Samsung Galaxy S22 Ultra] phormskaran:
Usally the German Telekom hasn’t given 5G SA to their Private Customers only Business Customers can use 5G SA but because of the Massive Public, Uploads and Downloads are happening so that why Telekom has given 5G SA only for the Octoberfest Area. In Germany we don’t have mmWave that why your trick helped me out a lot;)

I’ve honestly faster 5G Speeds then my friends with their European Exynos Samsung Devices 😄
[Samsung Galaxy S22 Ultra] mjohnson4580:
I'm not sure if I am doing something wrong. I have the S22 Ultra unlocked on a esim from Verizon. I followed the steps in the first post. I did have to use the samfrp tool. Everything went fine with that. My problem is any time I try to access the service menu a little pop up happens( screen shot attached). I have tried restarting the phone. I have ran the samfrp tool several times and I still always get that little pop up. Would disabling the cid help? I am not sure what to do at this point.
[Samsung Galaxy S22 Ultra] peacey8:
The code should work without you pressing call. It should open the service mode menu directly after entering the last "#" character.

Did you try both codes to see which one works? Did you try the *#73# code and not just the long code? Also make sure you're using Samsung Dialer.
[Samsung Galaxy S22 Ultra] mjohnson4580:
Yes I've tried both codes. The only code that works is *#0808#
[Samsung Galaxy S22 Ultra] peacey8:
Hmm, that's odd. *#73# should definitely work after unlocking the codes with SamFW, as it did for multiple people here on S22U.

When you used the SamFW tool, did you get a pop-up on SamFW telling you that the secret codes were unlocked at the end of the process?

Also, what software version and build number are you on, and which CSC are you using?
[Samsung Galaxy S22 Ultra] mjohnson4580:
I dont really remember (secret codes were unlocked) that pop up just a donation one. I'm on verizon Esim csc. When i get home from work im going to try to swap sim cards and see what happens.
[Samsung Galaxy S22 Ultra] peacey8:
Ya that's right, the donation pop-up means it should have worked.

I am on the exact same version (One UI Beta 2) as you and *#73# is working here. I couldn't see the CSC in your screenshot, what does it say for "Service provider software version" when you scroll down in that software info screen? The CSC line is something like XAA/XAA,XAA/XAA or VZW/VZW,VZW/XAA for example.

One thing I would try is to use SamFW to change CSC to XAA (or change it to VZW if you're already on XAA), then try the steps again (including SamFW unlocking codes step). You can also try to change your CSC to GCF if none of those work.
[Samsung Galaxy S22 Ultra] mjohnson4580:
Here is the csc I have.
[Samsung Galaxy S22 Ultra] peacey8:
Ya honestly, it should work fine. I was on VZW too when I got the secret codes working.

As I said, I would try to switch CSC using SamFW to XAA or GCF and try the instructions including unlocking codes again.
[Samsung Galaxy S22 Ultra] mjohnson4580:
What CSC are the XAA and GCF? If that works do i change it back to VZW when done?
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Those are for any other networks outside US so if your outside US use it but if your using US sim change it to the proper CSC to unlock all the features of the network.
[Samsung Galaxy S22 Ultra] peacey8:
XAA is US unlocked and GCF is factory-default (global certification forum). You can change back to VZW if it does work and see if it still works on VZW afterwards.

Btw, why are you trying to unlock all bands if you live in the US and using a US sim? Do you want to enable all bands for when travelling?
[Samsung Galaxy S22 Ultra] mjohnson4580:
Yes I live in the US. Baltimore, Md to be exact. I was planning a trip and want to be able to use my phone.
[Samsung Galaxy S22 Ultra] peacey8:
A valid reason. Did you end up getting it to work by trying to change CSC first?
[Samsung Galaxy S22 Ultra] mjohnson4580:
No I tried two different csc like you suggested and nothing. I might try a factory reset then see if it works.
[Samsung Galaxy S22 Ultra] peacey8:
Ya maybe that is a good idea to try. I would also try to go back to Android 12 if you're resetting and it didn't work. Though it should work on Android 13 as it did for a couple of people.

One more thing, is your phone locked to Verizon currently or it's past the 60 days?
[Samsung Galaxy S22 Ultra] lexcyn:
Thanks for this! Flashing the U1 actually changed my CSC from BMC to XAA, and now I am showing XAC as my current home CSC which is fine with me!

And now I'm on Android 13 beta 3 which is running MUCH better than Android 12 was for me - plus 5G working great even though we only have NSA here.
[Samsung Galaxy S22 Ultra] warriorvibhu:
@mellojosh also has written this guide for Note20 Ultra.

Josh haven't seen you in a while buddy. Sending you best wishes. Hope you are doing well.

Also thank you OP for sharing this information along with your own updates.
[Samsung Galaxy S22 Ultra] peacey8:
Yes it's so nice to have n78 on Android 13 in Canada! I clocked in at 1.3 Gbps on Bell's network.

View attachment 5722577
[Samsung Galaxy S22 Ultra] lexcyn:
I don't have it at my location yet but I seem to have 5G icon all the time now vs before it would come and go (due to carrier aggregation). That's a plus too since that's how all other OEMs display it.

Also isn't n78 standard in the Canadian version anyways?
[Samsung Galaxy S22 Ultra] peacey8:
Yes it is in the Canadian CSCs already since a couple months ago, but I'm on XAA CSC on Android 13, so had to unlock n78.
[Samsung Galaxy S22 Ultra] danielcampos:
Good morning, I confirm the method works on the SM-G998U1 with android 13 beta 2, YES IT WORKS
[Samsung Galaxy S22 Ultra] Paradox:
After all the steps, bands are showing like this. Can anyone confirm whether I have unlocked all bands or not?
[Samsung Galaxy S22 Ultra] peacey8:
Yes all LTE and 5G NSA bands seem to be unlocked from your picture. SA bands are still disabled since you didn't enable them, but SA bands aren't needed unless your carrier uses standalone 5G networks (very rare right now). So everything looks good.
[Samsung Galaxy S22 Ultra] fsmeurinne:
If I do this would I lose the Samsung Care warranty?
[Samsung Galaxy S22 Ultra] thenormal1:
First, thanks for the great Guide 👍 all bands are enabled on my U1 XAA (both sims), but have still some issues...

Note: Its an eSim with 5G (o2 Germany)

1.Band 78-NSA-SA is enabled for Sim2 (I think only NSA is supported) eSim connects only to LTE5G (no solid 5G icon) what could be wrong?

View attachment 5728733

2. still struggeling with Network switch (while driving) it switches to N/A no network. Need to set FlightMode to enable it again. did already this, too:

Optional if you have issues going from LTE to LTE+ (carrier aggregation not working properly): Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> AS -> Next Page -> DISABLE CA COMBO CHECK -> DISABLE ON.

Thx for help
[Samsung Galaxy S22 Ultra] nnighthawk:
Hi, thanks for the guide. Extremely useful.View attachment 5728759

I'm on SM-S908U (locked) TMB firmware, One UI 5 beta 3, but had the same issue as Paradox above. All LTE and 5G NSA bands are enabled, but 5G SA bands are not. Only n41, n66, and n71 SA are enabled, as is default on Android 13 [edit: for TMB of course]. I've tried messing around a little more in the service menu to no avail, I can enable NRDC but not SA on all other bands.

Not sure what I can do, could the TMB firmware have something to do with it? Thanks again though, I was still able to enable other bands which is very useful, was just hoping I could do the same with SA. Specifically I want to enable n25 SA.
[Samsung Galaxy S22 Ultra] peacey8:
I don't think so. You're not modifying the software or installing non-official mods. But don't quote me.
[Samsung Galaxy S22 Ultra] peacey8:
I would try to disable SA bands if you don't use them, having them on can cause issues if your carrier is testing them but not using them.

So disable SA from the service menu and see if it helps connect to 5G. Also, are you sure you're in an area with 5G coverage? Have you tried to go around town to different areas?
[Samsung Galaxy S22 Ultra] Paradox:
esim has more SA enabled by default.
[Samsung Galaxy S22 Ultra] peacey8:
Oh it's weird some SA bands are not enabled. All of them should be if you enabled SA.

Did you change both of the following options in the service menu? Also since you're using eSIM, please be sure to change NR5G stack selection to Stack 2 first, or they will only apply to Sim 1.

Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> NR5G STACK SELECTION -> Select STACK 2.

Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> NR5G SA/NSA Mode Control -> SA/NSA ENABLE.

Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> PROTOCOL -> NR5G -> NR5G SA/NSA Mode Control -> Remove SA permit list.

After that restart, then dial *#73# and go to Band selection. Select SIM2. Then press [8] Select all bands. Then press [9] Apply band configuration. Then exit the menu and go back to it again to check that all SA bands were enabled.

Please see if the above helps.
[Samsung Galaxy S22 Ultra] fsmeurinne:
Thank you! It worked now I have 5G in my country with my US phone. Brilliant! I think I opened everything just in case. Just a question at least where I am now it is a bit intermittent connects to 5G and then changes to LTE+ not sure if it's the antenna of the place I am in?
[Samsung Galaxy S22 Ultra] danisonco:
Many thanks, got this to work on my G998U1
[Samsung Galaxy S22 Ultra] peacey8:
If you scroll down in your NetMonster app, you should find 5G NSA signal stats (RSRP and SNR), see picture below. What you're showing here is only LTE signal stats. How stable 5G is will depend on 5G signal level in your location.

Check to see what the 5G RSRP and SNR are when connected to 5G. If the 5G RSRP is very low (close to -100 or less) or SNR is very low (like < 5 dB), the signal to the 5G cell is not very good and it will switch to LTE+ intermittently when the signal drops. If the RSRP is high (-60, -70 for example) and SNR is high, then 5G should be very stable.

Did someone test this on sm 908 E? O couldn't find any specific method for the E version. Many thanks!
[Samsung Galaxy S22 Ultra] nnighthawk:
Hi, I've done these steps in that order multiple times to no avail :(
[Samsung Galaxy S22 Ultra] peacey8:
If you have a 908E model, you should test if this works for you and tell us. I don't think it will though, because you might not have access to the service menu.
[Samsung Galaxy S22 Ultra] peacey8:
That's really weird, I'm not sure why they're not showing up for you. That's all I and others had to do on their phone to get all NSA/SA bands to show up.

The one thing I can think is you are on U firmware instead of U1, and I'm not sure if that can make a difference. Is it possible to flash U1 firmware with Odin and see if it helps you, or do you need U firmware? If you use HOME_CSC (instead of CSC), it shouldn't wipe your device when switching to U1 firmware.

Before you flash U1 though, you can also try to switch to GCF CSC first like this (instructions courtesy of @wr3cckl3ss1). GCF CSC should have all bands unlocked, but I'm not sure if it's available on U firmware. So might as well try first before flashing U1.

1. Go to: Service Mode Main Menu -> PROTOCOL STATE -> PROTOCOL SIMULATION -> IMEI PRE CFG SIMULATION.

2. In this menu, click [1] AP, then click GCF (last option). Then click [2] NET1 and change it to GCF as well. Do the same for [3] NET2. All GCF.

3. Press [4] Write. Then restart phone.

4. Check if all SA bands were unlocked. If not, repeat the band unlocking instructions and then restart and see again.

The above instructions won't change CSC completely (phone info will still have old CSC), but will "simualte" changing the CSC so that the service menu options reflect that new CSC.
[Samsung Galaxy S22 Ultra] nnighthawk:
Ok. I did the second method (all TMB --> GCF) and it worked perfectly! Most SA bands were enabled except n1, n3, n8, n20, and mmWave SA, which is completely fine. Thanks so much and if anyone else has the same problem, this method should work. Nothing changed besides the CSC in the service menu.View attachment 5729689

Are there any code for unlocked S908E with INS CSC? the one's mentioned in the OP does not work

No sorry I do not believe this method works for the E model, this is only for the U/U1/W North American model.
[Samsung Galaxy S22 Ultra] cass89:
Any workarounds for 908E? The Samsung band selection app says "hidden network settings activity not found on device".. I saw a post for another device to re-install it, but it requires a writable system
[Samsung Galaxy S22 Ultra] fsmeurinne:
I also think it's because if the 5G battery saving mode, as long as I am navigating it keeps it up, if not on use it drops to LTE+
