Tried it on two S22u (S908U1) both with XAA csc one is using a foreign sim (Globe Tel PH) and another T-Mobile on the other s22u and a fold 4 for on u1 (F936U1).

Changed both csc's to VZW and did the steps.

I had to use adb shell pm uninstall -k --user 0 com.samsung.android.cidmanager in order to remove the annoying popup and forces a reboot then boots into a CSC based on carrier which nulls csc change depending on carrier.
[Samsung Galaxy S22 Ultra] peacey8:
Thanks Big Dave. I didn't think about this step since I installed the drivers ages ago, but you definitely need them for this to work. I will make a note of it in the tutorial.

Glad to see it worked for you and @formula666 after installing the driver!
[Samsung Galaxy S22 Ultra] netnerd:
after i installed the Samsung driver. it works on android 13 beta2 !

thanks !
[Samsung Galaxy S22 Ultra] peacey8:
Thank you for confirming it works on Android 13 as well. Very happy to see it worked!
[Samsung Galaxy S22 Ultra] jorgelreza:
hi folks, can i flash s908u1 on my s908u att S22U?

I would like to remove everything that the operator brings, what fw do you recommend?
[Samsung Galaxy S22 Ultra] dj24:
Assuming the other way works as well I presume? That is if you're travelling internationally outside of the U.S you'll pick up more bands?
[Samsung Galaxy S22 Ultra] peacey8:
Yes that's a valid use case as well.
[Samsung Galaxy S22 Ultra] WannaB101:
This. Verizon does a horrible job previsioning their service in my area. I will constantly have full bars, but zero service. Since disabling this, i don't have to turn airplane mode on and off to regain signal.
[Samsung Galaxy S22 Ultra] phormskaran:
Hi i have done the Steps but im not receiving 5G here in Germany as you can see only 4G not even 4G+ kindly let me know how i should proceed further and if the 5G Bands are ok thanks :)
[Samsung Galaxy S22 Ultra] peacey8:
It seems like all your 5G bands are unlocked and enabled.

Which ISP are you using? Do you know which 5G bands they use, and whether it's NSA or SA?

Have you confirmed you're able to get 5G or 4G+ before in this area with a German phone?
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Does Globe sim can detect the 5G signal using your phone?

If yes can you screenshot the phone info using code *#0011#.

I want to know what's LTE anchor band of the 5G. Thank you!
[Samsung Galaxy S22 Ultra] Abaddon:
Yeah on n41. Even with Smart n41 and n78
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Thanks for the screenshot Globe uses LTE band 1 for anchor band on your location.

I tried your method but I'm on note20 ultra 5G U1.

I'm using Smart but it shows not restricted on 5G with n41 band.

5G on my location uses band 3 for anchor band.

Have you done other methods because on my case the combo on LTE anchor band and 5G uses anchor band 41 with n41 5G. Even I removed prune combos or edit it manually.

I confirmed it when I tried to get the UE logs.

Did you try something else before that?
[Samsung Galaxy S22 Ultra] phormskaran:
Hi the Problem got solved thank you very much for your idea with the bands im running 5G here in Germany with high speeds and that without having that laggy at&t U firmware

I have attached a Screenshot of the Speedtest

Thanks a lot againView attachment 5707743
[Samsung Galaxy S22 Ultra] peacey8:
That's good to hear! How did you fix the problem? It just fixed iitself or did you do anything?
[Samsung Galaxy S22 Ultra] aspiens:
After all the manipulations through the * # 73 # menu, the item in the smartphone settings menu with the choice of the NETWORK MODE has become inactive. Only automatically. Can this be changed somehow, or can I reset ONLY these settings, and not reset the entire smartphone? I tried to do all the points of the instructions as it was at the beginning, the item in the settings is still inactive. Device model 908U, T Mobile.

Can I flash through the CSC_HOME file alone to restore all the aggregation settings to the factory state, without resetting the entire smartphone to the factory settings?
[Samsung Galaxy S22 Ultra] digheaditya67:
Ok , a new thing about note 20 ultra....

I just went through the file for esim of note 20 ultra using qpst , and it has this in its comments file in the xml file for carrier policy

( carrier_policy.xml_Subscription01 )

View attachment 5851429

So it does support n78.

I have a US based Verizon model running unlocked U1 version.
[Samsung Galaxy S22 Ultra] sebdevF:
Hello, I have an S22 Ultra SM-S908U1 and updated to ONE UI 5.1

I would like to be able to access 5G and LTE+ in France.

My question is should I flash or can I directly open the access with the codes? When I enter the codes I get an error message. THANKS
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Setting CSC to GCF unlocked all supported bands of your phone and based from my research modems are soldered differently on U/U1 note 20 so editing software files does not unlocked more bands.

Sorry but I'm talking about the n41 5G NSA which is already unlocked. But the problem is n41 is locked on b41 LTE anchor band only and it is configured on the firmware and not on the modem so it can't be modified.

I tried everything on qpst tool. Removing gcf whitelist. Adding combos manually. Editing carrier policy, etc. But still it doesn't work.

I need the b3+n41 or b1+n41 combo so 5G NSA will work on my network. (SMART)

[Samsung Galaxy S22 Ultra] peacey8:
Please read the OP instructions. You are already on U1, you don't need to flash anything. You just need to unlock the secret codes with SamFW Tools first then you can use the codes to access service menu (see part B and C of instructions).
[Samsung Galaxy S22 Ultra] sebdevF:
I use SamFx latest version 4.1

I don't have « DM + MODEM + ADB » .

I have :

View attachment 5852801

Which is the good one ?
[Samsung Galaxy S22 Ultra] peacey8:
Turn on ADB debugging in the developer options first of your phone. Then DM+MODEM+ADB will show up.
[Samsung Galaxy S22 Ultra] sebdevF:
THANKS. How do we do that ?
[Samsung Galaxy S22 Ultra] peacey8:
Go to Setting -> About Phone -> Software Information -> Click Build Number 5 times. Then go to Settings -> Developer Options -> Turn on USB Debugging.
[Samsung Galaxy S22 Ultra] sebdevF:
Yes now I have the DM+MODEM+ADB.

But I can't go any further than waiting for DIAG ???

Any idea to fix it ?

View attachment 5853013
[Samsung Galaxy S22 Ultra] peacey8:
Did you install Samsung USB drivers first? It's linked in the OP.
[Samsung Galaxy S22 Ultra] sebdevF:
Thank you so much. Everything works now.
[Samsung Galaxy S22 Ultra] peacey8:
You were able to unlock the bands and 5G works for you now? That's great!
[Samsung Galaxy S22 Ultra] digheaditya67:
Well I am very less aware of the NSA 5G, coz my operator has got only SA deployment, which makes it even harder to connect.

Well, in your case does DSS ( Dynamic Spectrum Sharing ) not help you ?

-----------------------

I guess you are right, we are left out with nothing .

I actually have a Verizon - note 20 ultra // but flashed with U1 firmware

I had certain hopes after reading this post, and there even 2-3 more related to s20 ultra claiming the same, but seems like they must have mistook something else for that.

[Samsung Galaxy S22 Ultra] Anmolkvm:
Tried this. Worked on my fold 4. 5g works fine too with good speeds. But whenever i make or receive a call, 5g switches to LTE and even after the call is over, doesnt switch back to 5g again. To make 5g work again, either i have to leave the phone idle in standby mode for a couple of minutes or manually have to switch to LTE and then back to 5g in network selection. Used to work fine before UI 5.1 update. Been a problem since i have updated. Quite frustrating to do it everytime. Any resolution please? Am i missing something?
[Samsung Galaxy S22 Ultra] ElIT3ShOOT3R:
Will this work on A53 OneUI 5.1 if I can flash the US firmware?
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
When I said I tried everything I really tried everything that is available on the internet so DSS is also one of those.

Maybe rooting or using the shell exploit can be used to fix it but no one knows how to do it. Only Samsung can make this thing work.
[Samsung Galaxy S22 Ultra] abuchison:
This thread helped me to open up 5g SA mode but it is kind of stupid Samsung disabled SA by default. My S22+ could only connect 5G NSA before the hack.

really appreciate
[Samsung Galaxy S22 Ultra] ms.goofy:
I can confirm that this method also works on S21 Ultra 5G SM-G998U1 with the latest updates (One UI 5.1). You can add it to the "confirmed to work on" list.
[Samsung Galaxy S22 Ultra] JazonX:
Hey There;

Which method exactly worked ?
[Samsung Galaxy S22 Ultra] ms.goofy:
For SM-G998U1:

A. Device ready had US U1 XAA firmware.

B. Had to use SamFW FRP tool to unlock service menu secret codes. (Do not forget to install samsung usb drivers)

C. All bands could be unlocked using the service menu (method 1)
[Samsung Galaxy S22 Ultra] prrhoh:
Hello Folks,

I have the S22 (S901U1), using in Dubai.

When I first inserted the Physical SIM - upon booting - my phone instantly showed 5G. But, in order to first set it up, and trransfer data from my earlier S20-5G (also US variant) - I removed the sim from s22, installed all the updates Transferred my data from S20 (with 5G working), re-inserted the sim back in S22 to start using it - and never saw 5G again - Only LTE.

Everything works but 5G.

So last night I unlocked all bands using method 1. ( Successfully I presume)

- Got Samsung android drivers for s22

- FrpTool - unlocked verizon secret codes (with difficulty - SS attached) as I never got the option of "DM + MODEM + ADB" - so selected all options one by one and eventually unlocked the Secret Codes.

- Followed the steps - unlocked all bands, and I think Im looking at LTE+ (I dont remember looking at LTE+ earlier) -

but still no 5G

.

My s20-5G however does get 5G intermittently with the same sim card at the same locations.

Attached screenshots of RF TEST MODE, USB Selection , as well as CELLMAPPER.

Can anyone please tell me if I have unlocked all Bands or atleast the required bands (n78 for this region).

- Have spoken to the operator customer support - and reset network settings many times - useless.

- S22 with OneUI 5.1 and march security patch.
[Samsung Galaxy S22 Ultra] TechSavvySourabh:
thanks man, this is actually worked in my S22 ultra US variant, holy moly ,youre awesome bro, very very thanks, this will work in india with jio 5g,prevoiusly i cant use jio5g but this method will enable jio5g which is not officially supported by network.

sorry for my english
[Samsung Galaxy S22 Ultra] RaulRivera:
I hope someone can help me.

I have an unlocked s21+. When I go into download mode, my carrier is Verizon. The binary is official Samsung.

I flashed the XAA firmware via Odin with the most recent update and it gives me a GCF/GCF,GCF/VZW.

I enter *#73# and I can do all the commands in the instructions perfectly, but when I restart the phone, my bands are still blocked and only the default ones work.

Can anybody help me? I have been trying to fix this problem for 3 days and I haven't been able to. I'm desperate.

Thanks in advance.

Any chance of getting this to work on an S21 FE? G990U1? Its not working
[Samsung Galaxy S22 Ultra] Dyonas:
I have an S21+ in the UK but it's a USA phone with SnapDragon. I can confirm that it works for that too. I originally had G996U firmware on it, flashed it to G996U1 firmware then enabled the service menu. Method C worked for me and enabled 5G on O2, band n78 is used by all UK carriers. The previous security patch didn't change it but the 1st April patch disabled it so I had to redo the process from method C and it works again. Hope that helps someone!
[Samsung Galaxy S22 Ultra] drnhzn:
Hello, I need help

This was working for me for a few months now until it broke last week. Tried reformatting and flashing the firmware then redoing the instructions and it's still broken.

What's happening now is everytime it switches from 5G to LTE or vice versa both sims loses signal for 10-15s this happens multiple times a day and my battery depletes like crazy and my phone gets hot.

Attached a screenshot below of what it looks like when the signal drops. Using S22 Ultra SM-S908U1 (XAA) with one physical sim and one e sim

Thanks!
[Samsung Galaxy S22 Ultra] Sillyhippyjoe:
Is anyone else having issues with the CSC changing back after you put in your sim card?

I tried finding and disabling CIDManager - I couldn't find it nor could I find an option to show system apps

So I took out the SIM card changed to CSC to Verizon, followed steps to unlock Verizon secret codes and I still can't get to the service menu I get error "Enabling secret code... Error when send command The 1/0 operation has been

aborted because of either a thread exit or an application request."

[Samsung Galaxy S22 Ultra] ljohn2:
Yes it is service mode. It's an option under

my question is what does this option do?

[Samsung Galaxy S22 Ultra] DrPhant0m:
I searched this thread for 908B and got no results. S908E has some results, but I don't think any relating to my question...

I'm trying to find out if the International versions (SM-S908B, SM-S908E) support ALL of Verizon's 5G bands, including UWB. (Obviously I want root and 5G).

I can't find a straight answer online from a reliable source that I also understand (some sources have a lot of technical info that I can't process).

Many sources just say something like:

SA/NSA/Sub6/mmWave

... but don't articulate which bands. Does "mmWave" suffice to say that n260 & n261 are supported?

Bonus points if you can comment on the S23 as well.

Thanks!

[Samsung Galaxy S22 Ultra] DrPhant0m:
Is this an emerging exploit for the S22 series, including the US "U" versions? I just checked the "development" filter for this device, and didn't see any other mention of it yet - just the typical TWRP and ROM posts that assume you have unlocked BL and/or root already.

What can be achieved? Just root or bootloader unlock as well? Would either/both be permanent?

Thanks for the info! (I just don't understand all the technical details...)

I have a Rogers S908W, never flashed any firmware on it. I've dabbed in flashing firmwares a loooooong time ago (last time on a 1st gen Pixel XL) and just haven't had the need to do it again until now. Tried searching the forums but haven't found a clear answer.

- Will doing this enable Dual SIM, Dual Standby (DSDS)?

- Should I go with the XAA firmware, as I understand XAA is the US Unbranded one?
[Samsung Galaxy S22 Ultra] jcsww:
There is no dual-SIM on US models. There is one pSIM and one eSIM for DSDS but you can't enable dual pSIM.

Hello, I followed all the settings for enabling the 5G bands on my Samsung S-S908U1 (S22 ULTRA), and in band selection i see all the bands are showing active, but i still dont see 5G on the phone , it always stay to LTE but yes the speed of internet has improved and i get high speed many times but then after a while the internet again gets stuck
[Samsung Galaxy S22 Ultra] nnighthawk:
Hi, what carrier (operator) are you using and in which country? If you did all the steps correctly your phone should be able to connect to 5G without issues, unless the network explicitly does not allow your device to do so.
[Samsung Galaxy S22 Ultra] nnighthawk:
Only the U / U1 models have the mmWave antenna, I don't even think the W models (Canada) have it. This also applies for the S23. Also, no guarantee that international models work with Sub6 5G on Verizon.

Would Be Great if anyone can help

How can I restore all these settings to default original settings?
[Samsung Galaxy S22 Ultra] po8pimp:
You can reset all of your network settings by following this Reset Network S22 Ultra. After you have done that go to Settings>Connections>Mobile Networks>Access Point Names, click on top right 3 dots, then select Reset to default. **Note** if you have a custom AP configuration, it will be lost so I recommend screen shots so you can rebuild it. Also you will lose all your connected devices and have to re-pair/reconnect them after the Network Reset.

Hope this helps.

@peacey8 recommend adding this to your OP so others have it. You can re-write it however you feel. Great post/writeup BTW.
[Samsung Galaxy S22 Ultra] varun.jaiswal:
Hi - Why will anyone enable bands if they are staying in US/CA? People are looking at this option only when they move out of their respective geography and devices refuse to work in other regions. Samsung Customer care has been pathetic in addressing the concerns of their consumers for devices they sold for $1000+. Have experienced that personally. Samsung is not giving any options to customers - either throw their mobiles or resort to ways like this. Thanks
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Yes. For roaming, people who bought the phone because of snapdragon processor and for band locking purpose.

If you're on US just stick to the default settings.
[Samsung Galaxy S22 Ultra] wr3cckl3ss1:
BadSpin works fine on S22. I've compiled for S23 as well but the exploit just runs on and on.
[Samsung Galaxy S22 Ultra] wr3cckl3ss1:
You must be new around here.

Welcome!

Let me be the first, to say this in the most professional way possible.

WHO....CARES.....!?

Customers shouldn't be held down like slaves to a carrier company. You buy something, you should be able to access any and all information on something that's yours without fear of losing service or be penalized for enabling a band thats yours anyways but because AT&T or TMO say you can't use it because it's incompatible....give me a break please. The biggest thing, companies do is keep customers out of the loop and held under their false pretenses, to control and dictate the market and spectrum.

I have recently bought Fold3 in india via amazon which delivered me US varient unlocked Fold 3 (XAA) ,i.e , no 5G, no Call recording issue. Call Recording problem was fixed with Automatic Call Recorder by Appliqato ACR.

Now this 5g problem was still there, i have tried chainging CSC, Firmware, no luck so i have droped the idea of getting 5g from rest for my years untill now. i have came accros this post and got a guy updating JIO 5G working with this method. SO gave a try and i have finally got 5G network sucessfully working on US varient Fold 3 5G 512gb Confirming with screenshort attached. for JIO app itself showing non 5G device in 5G network, Speedtest 5G vs 4G

Have you found a fix for this issue? I'm having this now tried different settings on the service menu but now the 5G status only shows not restricted.

Edit: it connects again to 5G for a few seconds then it lost signal everytime
[Samsung Galaxy S22 Ultra] SidRose01:
Which step are you exactly referring to when you said, "you need to change the NR5G stack before changing the NR5G related options above" ??
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Found a temporary fix on this.

Firmwares after March security update has this issue.

So downgrade to S908U1UES2CWB7 .

I don't know if this is a bug or samsung is getting rid with the bypass?

I also experienced signal loss when I'm experimenting on note 8 and note9, when I put an unsupported CA combo manually using efs tool. So I'm positive that this is a bug on the modem configuration only.

I blocked the software update using samfw for now. Maybe I'll update this when oneui6 is released.

Here's the proof.
