any method to protect it from getting removed on every time "factory data reset" ??
[Samsung Galaxy S22 Ultra] OneOfMany07:
Do more unlocked bands mean higher power usage over time? Or does it just unlock use with more towers? Or the ability to detect them too (like for cell tower mapping).
[Samsung Galaxy S22 Ultra] OneOfMany07:
I assume you'd need to modify the image somehow. By default the service menu is disabled, right? I've never tried to do anything like that.

Wonder if an image of before/after could be done, and you focus on the difference(s)? Then you'd know what it changes when applied.
[Samsung Galaxy S22 Ultra] soyeb786:
same with me and speed is also slow

Is restoring the factory can fix this?
[Samsung Galaxy S22 Ultra] Sumsun:
Does this method still work on Android 14? To unlock a S908U.
[Samsung Galaxy S22 Ultra] volcolm:
Method 1 works fine, all bands enabled. Latest update, have had XAA FW since buying this phone a year ago and kept updated. No issues enabling anything. Went without a hitch aside from wireless kb/mouse dying halfway through.

Read the manual thoroughly. Don't touch menu items that don't need touched.
[Samsung Galaxy S22 Ultra] markuycalasin:
I already enabled all the bands but I still can't pick-up stable 5G. 5G logo will come out for a maximum of 5 seconds then it'll be gone. I live in capital of the philippinrs with very good 5G network. All my other devices are showing 5G except this one. 😭

[Samsung Galaxy S22 Ultra] jcsww:
Devices won't sit on 5G unless it's SA or the significantly better of the signal. There is no need for a device to idle on 5G except when it is using StandAlone 5G.
[Samsung Galaxy S22 Ultra] markuycalasin:
idk but my s23U is always showing 5G. while this one is LTE. s23U is PH variant though.
[Samsung Galaxy S22 Ultra] jcsww:
Different variants might have different bands available and different settings for carrier aggregation.
[Samsung Galaxy S22 Ultra] markuycalasin:
makes sense. it's my first time using a phone from the US. I am really anxious about this 5G thing coz pixels don't have 5G here in the Philippines.
[Samsung Galaxy S22 Ultra] jcsww:
My T-Mobile USA SIM only sits on 5G when SA is available. My Canadian SIM in the same device, the network (Rogers/AT&T) doesn't have much SA at all. To make that line go on 5G, I can download a large file so the devices realizes that it needs the higher bandwidth and switches automatically to 5G. When it's done, it goes right back to LTE.
[Samsung Galaxy S22 Ultra] markuycalasin:
Have you tried to maually set your preferred network to 5G only? Coz when I set mine to 5G only my phone goes to "emergency call only" or "no service" mode.
[Samsung Galaxy S22 Ultra] jcsww:
On T-Mobike, I live in an SA coverage zone so it's fine for that line to be set to 5G only. My Rogers line though, will do the same as ypurs when set to 5G only, because non-SA coverage means the device needs 4G/LTE, 3G, or 2G for calls. Only networks that have deployed 5G SA (StandAlone) can make calls over 5G coverage.
[Samsung Galaxy S22 Ultra] testivaao:
Hi everyone,

I have a Samsung Galaxy S20 FE 5G bought on a marketplace and I discovered that it was in US version (U1). I followed the tutorial in the hope of solving my network problems (bad LTE) but the problem persists, even with method 2: I do have the bars displayed with "LTE" but I have no internet speed. I've put my sim in another phone and there are no network problems, so it's definitely a problem on the S20. Any ideas for solutions? Does the tutorial work for 3G/4G too? Thx
[Samsung Galaxy S22 Ultra] broderickclayburn:
has anyone found a similar way to do this from sevice menu for the Samsung galaxy A14 as I have a unlocked T-Mobile device and it only supports NR bands 25,41,66,71 and I need to enable or unlock the bands for Verizon specifically n77???!
[Samsung Galaxy S22 Ultra] imblfmstr:
Hello Sir

Sorry if its a dumb question. I have specific query regarding step 6 above. I have S24 Ultra U1 dual sim enabled and using unlocked phone in India. For enabling all 5G bands should I carry out the step 6 first before following steps 1-5 of Section C method 1.

Thanks
[Samsung Galaxy S22 Ultra] imblfmstr:
You mean even after the update the bands remain unlocked ?
[Samsung Galaxy S22 Ultra] RowlyRowl:
my phone is pretty much the same as your screenshot .

NR Available (NSA): false

if i insert my sim into my pixel it shows true and 5G works very well

thats the only difference i can see. im figuring my phone is blocked from 5g by koodo my carrier
[Samsung Galaxy S22 Ultra] soyeb786:
How to reset all these settings ?
[Samsung Galaxy S22 Ultra] YakirOz:
Galaxy S21+ 5G

Very few LTE bands, not able to connect to any network but to T MOBILE 2G (I can only select the following: B1, B3, B38, B39, B40, B46, B48)

Followed the instructions, no change. If I'm choosing "LTE FDD only" then many options are selected (even those which are not shown) though I can not apply them later.

Anyone had similar issues as me? Any ideas on whatI can do to fix this?
[Samsung Galaxy S22 Ultra] SoNic67:
Everyone ignores the fact that there are filters in the phones. Filters that might not be physically present...
[Samsung Galaxy S22 Ultra] gedster314:
From isn't working for me using the enable hidden Verizon option. Not surprising since I'm trying to enable it on a SM-A156M/DSN. I was hoping I would get lucky.

I would like to be able edit what bands this phone uses. Anyone have any other suggestions? I would rather not go down the Odin flash US firmware road.
[Samsung Galaxy S22 Ultra] screening4ashes:
What's the current state of the Galaxy S22 with this tool? I have a USC model (US Cellular), it is network unlocked, but it doesn't have the right settings options enabled for my carrier, which is a small regional carrier who uses the XAA model SM-S901U1. As far as I can tell, the hardware should work, but there are software blocks related to the USC firmware.

Anyway, I tried the toolkit, I got Shizuku running both from Wireless debugging without a PC, and also from USB debugging through my PC. In both cases, Shizuku gives no errors and claims to be running, and the Samsun Toolkit (2.0.3) is listed as an approved app, but in both configurations it times out saying "Shizuku failed to respond within the allotted time."

is it the latest firmware from Samsung? the first thing my local carrier service rep did was update the software on the phone to the latest version, and then proceeded to tell me it's an old model S22 which doesn't support VoLTE... Rubbish! my Galaxy S10 works on their network, and VoLTE is the defacto necessary standard for all phone services in the USA today, AFAIK, it's just a carrier/SIM menu issue I guess, or a firmware issue.

In any case, I've seen others have been able to use the Toolkit and gain access on their S22s, but it is not working for me. Additionally, I tried cross-flashing with an S901U1 firmware, and it stalls on "SetuppConnection".

Do I need to downgrade my firmware to a previous version of the USC firmware and then from there do a crossflash with an SM-S901U1 XAA firmware?

Does anyone have any ideas or suggestions or recommendations for me?
[Samsung Galaxy S22 Ultra] jcsww:
US Cellular is more than likely the issue. Every time I have had to deal with them, they tried to concoct some b/s reason why I device did not work on their network when it should have. Did you purchase your device from US Cellular directly? If not, the IMEI won't be in their system and isn't whitelisted to use VoLTE on their network. Converting the firmware won't make any difference. They will stand by it not being compatible no matter what you prove to them. They do the same with their carrier roaming agreements as well. As a T-Mobile USA and Rogers Canada customer. If I did not purchase my device directly from my carrier, it is not allowed to roam on to US Cellular even if there is a carrier roaming agreement in place unless that device was purchased directly from the carrier that is their roaming partner. However, buying a device from their roaming partner and trying to use it with a US Cellular SIM will also get you told, the device is not compatible and will not be provisioned for VoLTE. They pretty much do the exact same crap that AT&T does.
[Samsung Galaxy S22 Ultra] screening4ashes:
Actually, it's the other way around. The device is from US Cellular, but it is Network unlocked, and it's not working on my tiny local regional network, which is an outfit called "Pine Cellular" in southeast Oklahoma. Pine is too small to have special carrier phone made for them, and they just sell the XAA Factory Unlocked phones to their customers. So for the S22, they sell the SM-S901U1, and I have the SM-S901U with USC CSC... When I changed the CSC to XAA, I was able to reliably connect to LTE and get internet, but I still can't get the phone to register for phone service.

I have not tried any other unlocked carrier specific devices on Pine, except the first one I used was a Canadian Galaxy S7, it worked on Pine until they did their 5G upgrades, and kicked off any phones older the 5 years it seems. really arbitrary, and it seems they have become a lot more picky than the hardware would demand. Nevertheless, it is the other way around from what you were thinking, I'm not trying to get service from USC, I'm trying to use an unlocked USC phone with a different service provider. All I need are the bands and VoLTE settings revealed at the software level, I believe... but maybe I am wrong. If there's any way to get a carrier branded phone to behave and work just like the factory unlocked one, then I think it should work. Otherwise I need to sell this USC phone and buy a factory unlocked SM-S901U1 phone with the XAA CSC.

So, is it possible to cross flash a fully updated S22 with the XAA firmware and ditch the USC firmware? or is it all locked down tighter than Fort Knox now with the latest Samsung firmwares? Like I said, none of the methods I have tried for unlocking the bands or cross flashing it have worked yet.
[Samsung Galaxy S22 Ultra] jcsww:
You can flash it with ODIN to the latest XAA firmware that has the same bootloader version. Make sure.you do the flash that completely wipes the device to ensure you don't end up with any issues.
[Samsung Galaxy S22 Ultra] screening4ashes:
That's what I thought, and what I tried to do, and I got the following error:

I tried:

Odin3 v3.13.1_3B_PatcheD and

Odin3 v3.14.1_3B_PatcheD

I tried the regular Odin and it said there was a mismatch of some sort and wouldn't even try, like it was the wrong firmware for the device, which is why I tried the patched versions of Odin, but they both stall at "SetupConnection". and I read forum posts about that, and nothing suggested for getting past it has worked for me. maybe my firmware is no good, where can I find a good, latest XAA firmware? and any other suggestions would also be greatly appreciated!
[Samsung Galaxy S22 Ultra] jcsww:
Do you have the right driver installed for when the device is in Download Mode?
[Samsung Galaxy S22 Ultra] screening4ashes:
You sure do ask tough questions! which one is the right one? I already had a driver installed, and it didn't work, so I installed "Samsung-USB-Driver-v1.7.23.0" from mega.nz, some link I found either on these forums or some other tutorial site...
[Samsung Galaxy S22 Ultra] jcsww:
The one in the OP should be sufficient.
[Samsung Galaxy S22 Ultra] screening4ashes:
Wow, that's amazing... I guess I was mixing two different forum posts, and I must have installed different drivers from the different post. Once I installed the drivers from the link on this OP, everything just started working. Got the phone cross-flashed with the latest SM-S901U1 XAA firmware, and the VoLTE calls SIM 1 toggle just automatically showed up, the correct APN settings also just showed up automatically, and my SIM card worked without any configuration at all. Everything seems to be working great, so thanks for double checking my apparently shoddy work! You saved me a ton of hassle and time trying to resell this device and buy an original SM-S901U1 model.
[Samsung Galaxy S22 Ultra] volcolm:
I meant that the phone received the latest update, tested this method after, and still worked (someone asked a page or two ago if it worked with current system updates). But also can confirm the other way now: the phone just updated this morning as well, it's still functioning as expected.
[Samsung Galaxy S22 Ultra] imblfmstr:
Guys I can confirm now that US S24 Ultra S928U1 is working absolutely fine both with Jio and Airtel in India. 5G is supporting on phone networks and Jio is supporting True 5G which SA 5G.

Only one issue that is- this phones doesn't show as compatible 5G phone on MyJio app but 5G works fine though and I can take benefit of free unlimited 5G data on Jio
[Samsung Galaxy S22 Ultra] madbrain76:
I started with US firmware, XAA, T-mobile unlocked. Followed all the steps in section B. SamFw said it completed. *#73# works. But *#27663368378# does not, unfortunately.

I'm trying to unlock n77 band support for Verizon 5G, as Verizon just added towers in my area and there is a strong signal when using a Verizon 5G gateway that I currently have in trial. But on my phone it sucks, gets 1% of the throughput only, due to being on the wrong band.

Edit: I succeeded. The long code is just a shortcut for the service menu. But that turns out not to be needed. I was able to unlock all the bands for both stacks.

Time to get a free trial Verizon MVNO eSIM to test it.
[Samsung Galaxy S22 Ultra] Valiante:
I'm using an international model S22 in Canada.

I'm getting 5G now finally, thank you!

I am noticing on Telus it's not very stable, it keeps switching between 5G, LTE and LTE+. Any advice on what settings to change to make things more stable?

I know in the same area my work phone gets a stable 5G signal lock
[Samsung Galaxy S22 Ultra] imblfmstr:
Just updated my S24 Ultra to May Security patch and the Band unlock status is retained. I still have all bands unlocked and not required to go through the process again
[Samsung Galaxy S22 Ultra] Aeroxool:
Hey there,

I just read through this thread a bit, since I read quite a bit about stuff related to this I want to provide you with some links.

- First of all, the alledged leaked tool from Samsung to help enable the hidden menu, it's from a comment on reddit including manual on how to.

- Samsung USB drivers for Windows

- Also, if you flash the modem with a differen version or with a stock version to repair or change its behaviour, I would suggest to follow this sophisticated guide on how to correctly flash Samsung mobile phones, even though it is from 2015, but notice the first two steps in section 3, it seems it still applies the modem needs round about 10 minutes to recalibrate after a change from what I have read in this thread.

- Last but not least here is a link to the last known "original" Odin tool and a patched version (3.14.1 3b), the patched version is better if you try to crossflash FWs.

Have fun! I assume you will find plenty MMI codes for Samsung devices, not sure though wich of those on the net are still available since I didn't enable the hidden service menu yet, but ... if some MMIs you would like to work do not work after everything you have done so far, you could still try to set the phone into factory mode and try again, I've read the phones are supposed to accept more MMI codes afterwards.

@peacey8 maybe you want to add some info to the initial post, so people searching here save some time :)

cheers

Just remove the space.

Or just copy this 888371 its the converted ascii of XSG

after applying these settings finally carrier aggregation worked i got lte+ signal but i noticed by doing this it disabled the sa bands only nsa are enabled and i am still not getting 5g

my device is s22u u1 xaa
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Do this

View attachment 6108151

Then restart your phone.
[Samsung Galaxy S22 Ultra] Trex888:
i already tried this it enabled sa bands then carrier aggregation is gone it just stuck at lte

i live in dubai and here band 78sa is required to get 5g standalone and i can see s22u u1 xaa supports it but i dont know whats wrong and why its not getting CA and 5g properly
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Service Mode Main Menu -> UE SETTING & INFO -> SETTING -> SYSTEM -> Next page 4 times -> SET LTE BAND CONFIG -> SET DEFAULT LTE BAND.

It should unlock all possible CA combination.

If it doesn't work. Maybe it's just connected to an LTE band without CA support.

Try to know what CA combo does your carrier have and locked the two or more bands only then you should get LTE+.
[Samsung Galaxy S22 Ultra] Trex888:
as you can see after changing to xsg I got CA works lte+ but I see no 5g

Any advice?

yes i did test on same location my other phone redmi12 5g which has lot less 5g 4g bands compare to s22u and it gets stable 5g standalone and also my brothers iphone12 gets 5g all the time here

i dont know what else to do to enable 5g amd CA together

Does anyone know how to revert everything back to factory default settings?
[Samsung Galaxy S22 Ultra] Trex888:

Thanks for your quick response

Do you know how to revert everything back to factory default settings?

I think I played with lot of stuff in service menu which I am not sure and I would like to revert back everything default
[Samsung Galaxy S22 Ultra] kanandvardhan:
haha! and then you helped me get through this, thanks bud!
[Samsung Galaxy S22 Ultra] Trex888:
After many days of testing it Turns out it is connected to 5g indeed and i tested the speeds but for some reason it's not showing 5g indicator logo showing just LTE
[Samsung Galaxy S22 Ultra] Romeo Nickolas:
Try disabling cidmanger via adb then change CSC using samfw tool. You can try any CSC as long as you remove the ca combos on LTE and 5G via service mode or set protocol simulation to GCF

Latest Samsung USB drivers installed. Phone mode changed to DM+MODEM+ADB. Can't get past Waiting for diag. Tried installing diag drivers still have same issue. Trying to unlock SA 5g bands on S20 Ultra. I really need n77. Phone is on unlocked XAA firmware. Diag mode stuck on VZW & XAA csc. I've tried turning USB debugging on and off. I've tried different COM ports. I've even tried different DIAG modes. All get stuck on Waiting for Diag. Running Android 13 on the 2024 Security patch.
[Samsung Galaxy S22 Ultra] dubblecup:
Don't know but I got this far. Does this mean that all LTE frequencies are enabled?I'm now getting 2 options in Band Section. TMB and XAA. Whenever I choose XAA. and reboot the attachment is the result. And if I choose TMB the latter. Notice there's no 5G bands enabled. Not really concerned about it because my sp doesn't offer 5G.
[Samsung Galaxy S22 Ultra] peacey8:
The two sections in the Band Selection are for Sim 1 and Sim 2. They're not for you to select and reboot, it's for checking what bands are enabled on which SIM. Since you only have one sim, you should always click the first option and see what bands it lists there.

What bands does it show you listed when you click the first Sim in band selection (I'm guessing TMB)?
[Samsung Galaxy S22 Ultra] cokeito:
hey m8

i got the monthly update just today, so bands were reset, i've done all the steps again, (also disabled the e-sim) and only using the normal simcard. I live on an area with full 5G coverage.

[Samsung Galaxy S22 Ultra] WF71:
Very nice for sharing such a detailed description on how to do this. And when Samsung and/or the carriers catch onto these methods and render them no longer functional like with Google dialer, Samsung Band Selection app, and the Sales and Net code change methods, we will lose yet another means of gaining access to these menus. Before posting threads like this, one should think first.
[Samsung Galaxy S22 Ultra] wr3cckl3ss1:
The community is here for help. It's unfortunate that stuff like this comes out in this way but i doubt Samsung is out here spreading their word or at the very least giving users a way to be more informed about their products. So what, if they find out. This is not something new and not something that theyll patch and repatch and then forget later about it. They are absolutely known for using their own tricks over and over. It's not about thinking before coming out and saying something. It's about giving people information that should already be given. You shouldn't have to beg...call or do anything outside the normal for them to give you a product that you paid for....period.
[Samsung Galaxy S22 Ultra] wr3cckl3ss1:
And because it looks like your new here. Check out the rules. You might of missed some the info about respect and respecting others. And I'm not trying to bash you or talk any kinds of wrong way. This site is for development and help. And thats what we need to accomplish here.
[Samsung Galaxy S22 Ultra] WF71:
Yes. I'm new on here, but not new to these methods on Samsung, which have been whittled down to only a few means left. Hopefully they aren't disabled in the future :/

Also, I have read the rules and my comment again, and hardly disrespected anyone on here. Perhaps you're are overly sensitive??
