Question.... I was thinking about flashing to U1 XAA firmware because my current firmware TFN (Tracfone) Doesn't offer LTE+ it just shows regular LTE, Does XAA firmware offer LTE+, also if I flash XAA firmware does the pop-up to restart the device depending on the sim card show up?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
It's not a firmware thing. It's a coverage thing.

No one can predict what will happen when you flash it. You'll just have to do it and see how it goes
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
I recently changed my ATT firmware to U1 as described earlier in my post. I seem to be getting worse signals in various places I normally received good signals. I am really not concerned about bars, but the data speed and voice calls breaking up bother me.

Some people suggest flashing only the mode (CP file from firmware), but It is my understanding that there is no way to go back to ATT firmware / modem because ATT does not provide it.

Any suggestions on how I can get my cell signal back to what it was on the original ATT firmware?

Thank you!
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You can absolutely flash a U firmware modem (CP file). Just make sure that the version is as close as possible to what you currently have installed
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
Thank you, but since AT&T firmware is not available, what U firmware modem that is available would be better than the U1 modem firmware I am running for AT&T?

Sorry if that is a dumb question and thanks again for your help.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
There is no such thing as "carrier firmware" for U models. They all use the exact same firmware.

Therefore it doesn't matter which carrier/region you use
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
Again, please forgive a potentially dumb question..... If I flash a U model modem to, each time I get a firmware update for the U1 model, I will need to update the modem firmware to carrier, correct?
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
Last question.. :)

I have G973U1UES6GUG1 installed and I had already downloaded G973USQU6GUH4, so would that be close enough to use to flash the modem from?

Thank you, thank you!
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Mismatched modems means you won't get OTAs. You'll need to manually flash every time you want to update

UH4 is the only bootloader 6 release so far for U firmware. So yes, that's the modem that you'll have to use
[Samsung Galaxy S10 Guides, News, & Discussion] magnumpi1:
Great information... Thank you so much!

I flashed the modem, but don't see much improvement at my house. Not sure if maybe ATT is changing something or if it has something to do with my phone and me changing the firmware to a U1
[Samsung Galaxy S10 Guides, News, & Discussion] Shawnx92:
Sorry I am this late, but I have a s10 att and I would like to get it to global version so I can get updates without Odin since I am not in the US. I recently downloaded and installed image below. Thanks in advance
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If by "global version", you mean U1 firmware, then you may flash it at any time
[Samsung Galaxy S10 Guides, News, & Discussion] Shawnx92:
Ok thanks, so I should just flash a u1 firmware from samfirm or do you have links? Because I only saw a link from 2019 and also does it matter if my bootloader is locked or not?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You can't flash 2019 firmware when you currently have 2021 firmware installed. You need to flash a version which matches your current bootloader level
[Samsung Galaxy S10 Guides, News, & Discussion] Shawnx92:
Ok thanks for the info, will try the Oct u1 firmware btw is it ok to use home csc as to keep data or should I backup and use csc ?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You always need to factory reset when going between U and U1 firmware
[Samsung Galaxy S10 Guides, News, & Discussion] Shawnx92:
Thanks I successfully converted however I still see ATT in software provider, I am wondering if that will stop ota?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I don't know. You'll need to wait until the next OTA is released and then see what happens
[Samsung Galaxy S10 Guides, News, & Discussion] martytoo:
I doubt I will use it, but I don't know how to get to the various zipped files for flashing with ODIN. When I click on the link in the OP, the only file I see is in Androidfilehost.com is:

SAU-1-9.0 fr0m February of 2019. Where are all the zipped files located.
[Samsung Galaxy S10 Guides, News, & Discussion] Shawnx92:
I used sammobile with patched odin, worked great.
[Samsung Galaxy S10 Guides, News, & Discussion] martytoo:
I don't understand this answer. Where are the files for the firmware located? When I follow the OP it brings me to 2019 firmware!
[Samsung Galaxy S10 Guides, News, & Discussion] Shawnx92:
There is a website called sammobile that u can use to get files.
[Samsung Galaxy S10 Guides, News, & Discussion] martytoo:
Thank you, thank you!!

As an aside I have noticed that few on this thread use Verizon S10's. If anyone reading this wants to private message me I'm interested in what you have learned about using an S10 without the Verizon bloatware.

I hate the fact that they want $20/ month for Verizon backup. We had a way to force Samsung backup and Verizon seems to have locked us out again.

Furthermore I like the Verizon messaging because I can text from my tablet. But I could live without that. What I don't think I can live without is wifi calling because I live between 3 or 4 cell towers.

Thanks again.
[Samsung Galaxy S10 Guides, News, & Discussion] schwinn8:
Not to totally derail your question, but I used to be on VZ directly, and have switched to Total Wireless which is a VZ MVNO. I save money in the process while still using VZ towers. In addition, I'm using a G975U (unlocked version) which eliminates most bloatware but still allows me to access TW's voicemail app and I still get VOLTE/VOWIFI. I'm paying $60 for 2 lines (limited data, but I think the limit is like 12GB which we never get anywhere near).

That would be one way to eliminate bloatware :)

Note, that VZ has apparently purchased Tracfone, which is the carrier behind Total Wireless as well... so who knows what will happen in the future. But there's no contract, so you can always try it!

Aside from that, when I had my previous phone, I found that to keep VOLTE/VOWIFI you had to have the MyVerizon app loaded, otherwise it would break. So be careful removing the VZ apps. Secondly, don't give up VOLTE so quickly -at some point in the "near" future (they keep pushing the date) VZ will require your phone to be on VOLTE to function, as they are planning to drop support for phone calls without it (all the carriers are planning this).

As for bloatware... I don't get what people's obsession is for removing this. In my case, I ran my old phone with these things installed and they didn't take up any significant CPU or battery, so who cares? If you use a custom launcher, you can even hide those apps if you "don't want to see it". And I haven't used VZ apps EVER for anything.

I also like to hear you're backing things up... there are many alternatives to Samsung Cloud and VZ Cloud for this. Android backs up some things, but what else are you looking to backup that isn't covered by Android backup?
[Samsung Galaxy S10 Guides, News, & Discussion] martytoo:
There is a data backup for the apps on the Samsung Backup - at least that is what I believe. I think you get that with the Verizon Cloud too but I won't pay $20 per month for backup. The only thing with regard to the apps that is backed up by Google in their backup is which app is installed. The app data is not backed up - at least I don't think it is. ( I used to use the Helium Backup app until the Android version changes seemed to ruin that and when I rooted my earlier phones I used Titanium Backup.)

Another thing that I find silly is that it is so hard to backup and restore the home page layout in the Samsung Touchwiz home page system. Nova has an easy Backup and Restore function for home layout. I know about Home Up in Samsung's Good Lock app but all that I know about that app is that supposedly my home screen is backed up. If I remember correctly I have never done a restore with this.

And I can't send the current home screen layout in my S10 to my old trusty S8 because the version of Good Lock available on the S8 doesn't have Home Up. So I can't do a restore from the S10 to the S8.

I recently wiped my S8 so I could loan it to my son-in-law who had to order a new phone to replace his broken Pixel 3. (He is on some inexpensive plan that uses the TMobile towers and now has a Pixel 6. The S8 worked great as a temporary phone while he waited for the Pixel to ship.) I used Smart Switch to get many of the settings from the S10 to the S8 once he returned it but the home screen won't restore. We have 5 cell phones and a home phone cell puck on Verizon for $211 total. This includes unlimited data on 5 lines and a hotspot with Disney+ and ESPN+ on one line. So the cost is reasonable, the service is great and the only one not happy with the backups is this oldest user (me) who is about to become a septuagenarian.
[Samsung Galaxy S10 Guides, News, & Discussion] schwinn8:
I use Nova as well, partly because of the backup for the screens. My wife would historically just use whatever was there, but I moved her phone to Nova as well, because she'd usually ask me how to do something, and I didn't know how on the other launchers (or it was more complicated)... so moving her to Nova made sense.

For the other apps, I'm not sure a "true backup" can be done in all cases without root. That being said, in my previous device, people transitioning to the S10 found that Swift worked well for them (as a way to transition and to backup). In my case, I used Smart Switch for the transition, and I didn't really lose anything... any apps I cared about backed up fine with Google, it seems? Or they had their own backup via a login.

Yes, it is weird not to have a consistent backup system, but I found that the Google one seems to work even if it remains somewhat invisible. One thing to note there is to make sure that it's turned on. In the Google account, I think I noticed that one of our older phones was not automatically backing up to Google... after I turned that on, it has stayed on. I also use SMS backup separately (though I may not need to) and for photos I'm using Google as well, of course. Is there something else you aren't able to backup with these?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
This has gone off-topic. If you'd like to have a conversation strictly about backup and restore, kindly start your own thread
[Samsung Galaxy S10 Guides, News, & Discussion] martytoo:
What Titanium Backup and Helium did was back up the data in the apps.

Meanwhile I walked into the Verizon store today in the middle of my Christmas Shopping. I had my S10 and my old S8 with me. I asked what I could get for the S8 and you probably won't believe that they offered me $800 off the price of the new S21. So I will be living with the bloat for another 30 months.

(As I think I mentioned above we have 5 unlimited lines, one cell phone puck landline and one line has a hot spot.)
[Samsung Galaxy S10 Guides, News, & Discussion] Legitsu:
ok so I can't make heads or tales of his naming scheme

what in gods name do I download & flash

if I want to convert my Verizon G973U to the ATT Build so I can use wifi calling ?

just the user data?, does it need to match whats already installed as I am on the latest ota and I don't see a more recent user-data rom anywhere

is this even required? many posts seem to indicate that as long as its a 'U" variant it doesn't matter if the build is vzw or whatever wifi calling should work ?

@iBowToAndroid HALLLLPP <3
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
I see you haven't read the OP.

My naming scheme is fully explained in it, and also tells you exactly where to look for instructions on converting to another carrier's firmware
[Samsung Galaxy S10 Guides, News, & Discussion] schwinn8:
U1 builds are unlocked and crossplatform, so they "should" change to the carrier specific setup when it sees the SIM. However, sometimes this changeover doesn't work.

If you're on "U" then you may not have the switchable capability. In which case you can get the ATT U-version. I would probably recommend getting the U1 and seeing if that works.

Note, I had issues getting it to recognize (going to VZW, in my case) on my 975U1. No one could figure it out so I simply returned that phone (Ebay purchase) and got one that was already setup from the seller for my carrier (Total Wireless, a VZ MVNO). So, be warned that sometimes it doesn't work... not sure why.

Also note, if you ever have to activate a SIM on ATT (or VZW) they will check the IMEI and they will flat out refuse to activate it even though it should work (the hardware is identical, after all). The carriers are just jerks in this regard... so be aware of this.

If you have more questions, it would be good to know the full software version and your CSC info as well...
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
U also has the capability to switch the carrier setup (including bloatware). But like U1, sometimes it doesn't work
[Samsung Galaxy S10 Guides, News, & Discussion] Legitsu:
I found the instructions but the only ATT Centric Firmware I can find in-full and matches my bl/baseband is U1, which ATT explicitly states wifi calling is NOT supported tho there is some debate on the ATT Forums about whether or not wifi calling will work

Screen_Recording_20220803-132906_Settings.mp4

drive.google.com

also what exactly does user-data contain is that strictly carrier bloatware or does it contain carrier configs?

I also had trouble getting red pocket going on vzw I had to pull the sim and manually add the APN before reinstalling the sim

I Have a freedompop GSMA sim on order it will be in in a day or two I am not even sure if MVNOs have the same 'restrictions' as AT&T
[Samsung Galaxy S10 Guides, News, & Discussion] Legitsu:
so other then an annoying "sim not from verizon wireless" nag on startup everything works including wifi calling
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Great!
[Samsung Galaxy S10 Guides, News, & Discussion] Legitsu:
does the posted user-data contain all the at&t apps?

AT&T doesn't push there service software provider packager when you are on a mvno apparently
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Correct
[Samsung Galaxy S10 Guides, News, & Discussion] autotech40:
i dropped my g973u1 and broken the screen.bought a g973u for parts,was able to fix it easy,so want to use it.it has t mobile bloatware,but sold by sprint,and netheir will unlock it,even though mei number is clean.will this flash fix carrier lock?i'd like to clone my broken phone to the new one,can you even root the s10 on binary 6?
[Samsung Galaxy S10 Guides, News, & Discussion] autotech40:
appears the posted files are the 2019 version.i need

g973u1ueu6ivh1 firmware​
[Samsung Galaxy S10 Guides, News, & Discussion] autotech40:
lol,flashed the G973U1UEU6IVH1 to phone and it works,but is still carrier locked.its been awhile since ive messed with this stuff.ill have to get up to speed on how evry thing works these days.lol if anyone wants to clue me in feel free.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
If T-Mobile won't unlock it, then you'll need to get a 3rd party professional business to do it. However, since it's running the newest firmware, it can't be done at this time because there's no method for that version
[Samsung Galaxy S10 Guides, News, & Discussion] autotech40:
Thanks for replying,did they change how they carrier lock phone in binary 6?most 3rd party can do binary 5.where in the software/hardware is the lock located?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
EFS partition, like every other mobile device
[Samsung Galaxy S10 Guides, News, & Discussion] autotech40:
Interesting,thanks for info.so if i root both device and backup efs on broken one and flash it to new one. Will that work?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You can't root them. And even if you could, no, that wouldn't work
[Samsung Galaxy S10 Guides, News, & Discussion] anno2070:
Hi! I have a SM-G973U with TMB/XAA/TMB csc and carrier unlocked. Im currently out of US (Vietnam) and i cant use the sim.

Can the issue be solved if i flash U1 XAA firmware? Thank you.

P/s: I was able to use the sim for a while. But after an update (i dont remember, an A11 patch), cellular just stopped working. The sim is fine because im using it on another phone.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
These are very vague statements. Does the phone give you any error messages when you insert the SIM that you want to use?
[Samsung Galaxy S10 Guides, News, & Discussion] anno2070:
The sim is still working, i can check my contacts with the sim inside. When i attempted to choose network provider in Settings, it gave me error message that it just cant. The flight mode icon on quick setting pane just greyed out (dimmed blue). Did a factory reset before and it didn't fix.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Then the next step would to be try a firmware flash
[Samsung Galaxy S10 Guides, News, & Discussion] Mulzac1301:
I have Samsung Galaxy S10 SM-G973UI, Android 12, it is Network Locked to Sprint.

I use Global Unlocker and change provider to T-Mobile, but it remains network locked. I think they are both the same.

I am overseas and my GSM SIMM is not registering on the phone,but works on my other unlocked Samsung Galaxy 8 phone.

How do I unlock, will flashing a Custom Rom remove network lock?

Any Rom and instructions available?

Thanks for any assistance.
[Samsung Galaxy S10 Guides, News, & Discussion] schwinn8:
Network lock usually means that the phone hasn't been fully paid for, so the network has locked it from "traveling" to another carrier. You have to get Sprint to unlock it for you, before it can be transitioned to any other carrier. There may be other ways to get past that, but those are typically illegal and so they are not up for discussion here on XDA.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
No, flashing firmware will never automatically network unlock a device.

If you're the original owner, then you can contact Sprint to do it for you

If you're not the original owner, you'll need to pay a professional 3rd party business to do it for you. You can DM me for a recommendation if needed/desired
[Samsung Galaxy S10 Guides, News, & Discussion] CoalMiner122113:
Hey guys. My Samsung Galaxy doesn't have the option for OEM unlocking. In the download screen, FRP lock status is on, and OEM lock status isnt even an option. How can I bypass this so I can downgrade from android 12 to 10?
[Samsung Galaxy S10 Guides, News, & Discussion] CoalMiner122113:
For Added Context : MY CSC number was G973UOYN. I tried flashing it to the USC region firmware but that made no difference. I am now trying to flash it to the U1 version, XAA region, and hopefully OEM unlocking will be an option. Ive also tried turning off auto update and setting the date back but that didnt work either.
[Samsung Galaxy S10 Guides, News, & Discussion] CoalMiner122113:
Didn't mean to post this and dont see an option to delete...
[Samsung Galaxy S10 Guides, News, & Discussion] schwinn8:
G973U implies a US based / Snapdragon CPU phone. If that's the case, then you cannot unlock the phone - the bootloader is locked down tight. You cannot root/rom your phone, afaik.

In addition, you cannot downgrade from A12 to A10. The BL is often updated with android revisions, and it will not allow you to downgrade the BL. Since there is no release with a newer Android + old BL, you are effectively stuck at the higher level. As you can imagine, this was done to prevent rooting the phone, as well.

What are you trying to accomplish with the downgrade?
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You no longer need manual entry in order to get U1. For VZW, manual entry just means that you need to manually type the build into the PDA and Phone fields, and the CSC into the CSC field, and then check the box for manual.

Usually that means you're not using the right version of Odin. 3.13 3b Patched needs to be used for everything
[Samsung Galaxy S10 Guides, News, & Discussion] McHenry_kramer:
Just SIM unlocked an AT&T SM-973U and want to use a Verizon SIM, but it never connects for calling or data. I haven't flashed in a few years. Is there a rollup sticky with noob guide? I presume I will have to flash to make this work? I didn't think I should have to flash just to use another carrier, but I have seen where the WIFI calling and dual calling/data use won't work without a flash.

Thanks for any help!
[Samsung Galaxy S10 Guides, News, & Discussion] C-4Nati:
So I'm in the US and bought a T-Mobile S10 from Samsung directly but I have MetroPCS. I would have bought unlocked had I known the WiFi calling wouldn't work, so I flashed the Unlocked firmware via Odin and now I have WiFi calling. Someone else told me the TMK version -- which is apparently MetroPCS's own firmware for the s10 -- gives you video calling and and RCS, but on both links you provided I don't see any firmware for TMK. My phone was originally U, but now that it's unlocked it's U1. Can anyone point me directly at the MetroPCS firmware please?
[Samsung Galaxy S10 Guides, News, & Discussion] C-4Nati:
Hey mate, can you view my post directly above this? I meant to quote you the first time, but my brain isn't working lol.
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
1. DONT. QUOTE. THE. OP. It's completely unnecessary.

2. This thread is really only for the links. It's not a newbie/beginner's guide to flashing, as there are umpteen of those on XDA already.

3. There is no such thing as Metro-specific firmware (or any carrier-specific firmware). The situation is fully explained in the OP, and everything that you need to install Metro firmware is in the AFH links
[Samsung Galaxy S10 Guides, News, & Discussion] C-4Nati:
Sorry for the quoting. I'm nothing near a noob, I just flashed the unlocked version via Odin a few days ago.

Sure there is, T-Mobile's Firmware is what came on my phone, now it has the unlocked version's firmware. I did not see Metro firmware in those links, and I'm sorry I don't mean to be sound hostile in my previous comments, but is there anyway you can link it directly? In your OP it says TMK, but when I CTRL + F on all of those Firmwares, none of them have TMK in it so I don't know which one to use for Metro. Sorry for the quote mate. I just want some help finding the Firmware to give me video calling and RCS :crying:
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
Item #2 was in response to the user who posted before you.

Starting with the S8, firmware is 100% identical and universal among flagship models. Any version can be installed on any phone, and the bloat/carrier features that you get depends on which USERDATA you flash.
[Samsung Galaxy S10 Guides, News, & Discussion] C-4Nati:
Thanks for the info mate. So is unlocked what you would recommend then since the T-Mobile version it came as WiFi calling didn't work? This guy on Reddit swore there was a MetroPCS version that enabled video calling and RCS. FeelsBad
[Samsung Galaxy S10 Guides, News, & Discussion] iBowToAndroid:
You can absolutely install Metro firmware to make it look exactly like an original Metro model, using the links in the OP. Whether that enables video calling and RCS for you, I have no idea
