Hi - I apologize if this has been asked but I searched the thread and did not find anything. I bought a used S10+ (Verizon) to use on Total Wireless which is a Verizon MNVO. Previous Verizon phones work fine on TW and the phone's IMEI passes the Compatibility test for TW fine. When I put the sim in however, I get this message "sorry,your device can't be activated on another carrier right now.for help contact verizon" and the phone stops receiving messages or making calls. From what I can tell, this means Verizon has locked it.

Can I flash the U1 firmware to solve this problem or will it still exist after flashing? I have the G975U firmware currently since it is Verizon.

Thank you for any help in advance.

Hi

I was under the impression that won't get OTAs. I still has October patch Level on U1 Verizon.

I'm guessing I've done something wrong.. I have an At&t s10+ that I flashed the U1 software on. But I do not get OTAs. Shouldn't the service provider codes be XAR/XAR/VZW instead of VZW/VZW/ATT if I did everything correctly?

Need help

Thanks

Actually I just found out through Verizon that the phone is still under a device payment plan which is why it is locked. I don't think a new firmware will help at all. So I am going to have to return it through Ebay unfortunately (at least I hope so). Thanks anyway.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
Good job.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
For some reason, newer Verizon devices have to be SIM unlocked in order to be used on Verizon MVNOs (Total Wireless, Page Plus, Straight Talk, etc). Something with their new unlock policy makes it so that even their own MVNOs can't be used, which is something that doesn't apply to any of the other networks

Please excuse my ignorance, but I cannot figure out how to access the latest Verizon FW via SamFirm.

I see the following options under region for SM-G975U:

USA (AWS)

USA (TMB)

USA (CLW)

USA (DOB)

Realize none of those correspond with Verizon. I noticed something about manual entry early on in this topic, and assume I need to replace region with a manual input there. I've attempted USA (VZW), VZW, and Verizon in that field and get the below error each time:

Error UpdateCheck(): Could not send BinaryInform. Status code (200/666)

Error UpdateCheckAuto(): Could not fetch info for SM-G975U/USA (VZW). Please check the input data.

I'm at a loss as I've read through this entire thread, but can't find a clear answer. Appreciate the help with this.

EDIT:

I downloaded Frija which solved my problem. Thanks anyways.

Pls help me guys i recently purchase S10 plus unlocked version from dubai and now i cant get any update its showing software update to date and its july 1 2019 pls help me to update the device
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
Are you saying that you bought a G975U or G975U1 from Dubai? These are US snapdragon designations and can only be sim unlocked not bootloader unlocked. Try going to samfirm or another service and

search for firmware that matches your region.

Most US variants update based on the sim inserted. Hope that helps.
[Samsung Galaxy S10+ Guides, News, & Discussion] mujju85:
Yes this is us sprint unlocked phone pls help me which firmware should I download
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
If you have a G975U or G975U1, any firmware in the thread will work. U1 is the "unlocked" firmware without carrier bloat. U will have bloat based on your carrier.

If you flashing from U1 to U or flashing a U to U1, you need the patched Odin.

If you have one of the non-US models, you need to flash the firmware that matches your device.

I'd recommend using Frija and have it detect your device to make sure your getting the right firmware. Carrier doesn't matter.
[Samsung Galaxy S10+ Guides, News, & Discussion] mujju85:
This is my screenshot pls help me to download the correct firmware

I have tried to download via fiija this one
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
I think what we're all saying is choose U or U1 and follow the instructions in the OP. It works as we all can attest to. Good luck
[Samsung Galaxy S10+ Guides, News, & Discussion] aroy97:
Since you're in India I'd suggest grabbing U1 version which is for unlocked devices, in your pic you have Sprint CSC which will give you useless bloat.

Edit: Use XAA CSC to grab U1 firmwares in the future
[Samsung Galaxy S10+ Guides, News, & Discussion] mujju85:

You can't downgrade the bootloader. That's why it's erroring out
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
If you want to go to U1 flash the unbranded firmware with carrier sim card inserted. That should give you a clean install without the bloatware.
[Samsung Galaxy S10+ Guides, News, & Discussion] d0bander:
Ahh, so should I not tick / include the BL file in Odin when flashing?
[Samsung Galaxy S10+ Guides, News, & Discussion] jwarrior319:
You need to flash cp, bl, ap, and home_csc. The bootloader version is the 5th from last number, so 2CSL1 is bootloader v2 and 1ASD9 is bootloader v1. The latest U1 firmware is 2CSL1 and the latest U firmware is also 2CSL1. If your moving from U -> U1 or U1 -> U then you need to use patched Odin 3B.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Nooo. Flashing BL is mandatory. But you were trying to flash binary 1 firmware to a device that had already received a binary 2 update. Once that increments, you can never go back
[Samsung Galaxy S10+ Guides, News, & Discussion] d0bander:
Thanks, you guys are awesome. I am successfully flashing.

Bloatware is removed.

My ultimate goal is to be on an unlocked device, that has WiFi Calling. My T-mobile branded SG975U does not allow for me to enter unlock codes (which I have) and forces me to go through their Tmobile Unlocking App.

Is it possible to replace the firmware with a carrier that allows me to enter an unlock code once a new sim carrier is inserted and detected?

For example, could I bypass T-mobiles Unlocking App and enter my unlock codes if I flash my TMB U to U1 unbranded(XAA), back to a different carriers U-firmware?

I've flashed the carrier locked T-mobile phone to unbranded XAA SG975U1 firmware.

I've noticed after flashing, the WiFi calling setting is no longer there.

APN/Mobile Network settings are grayed out and the phone does not ask for an unlock code while my sim card is entered.

I am going to attempt to flash the U1 to the latest Sprint U-firmware with the sim card in, and with the SPR USERDATA file & HOMECSC (since this is the only USERDATA I can seem to find at the moment, but I'm guessing this file should be included in most U firmware downloads)

Also, on easy firm, I noticed there is "G975U1 U2 Fix Unlock" firmware. Not sure what that is for.

Or should I just save myself some trouble, and flash my unlocked Spectrum Mobile branded SM-G975U to a different firmware that has WiFi calling?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
T-Mobile stopped using unlock codes 5 years ago. None of their devices use them now. That's why no T-Mobile device will ever ask you for an unlock code - no code exists, and there is no place to type one in. The Device Unlock App is what now communicates the unlock command to the EFS partition, instead of the unlock code.

If you have an "unlock code", you purchased it from someone who's nothing but a scammer. There is no way for you to use the code whatsoever.
[Samsung Galaxy S10+ Guides, News, & Discussion] burrzoo:
Should it be possible to downgrade from N975USQS2BSLB (Android 10, Jan Security Patch) to the N975USQS2ASJ8 (Android 9/Pie, Nov Sec patch) and use Home_CSC to keep my data? Or must I do a factory restore then downgrade? Is downgrading even possible? I've tried flashing and Odin shows it was successful but my phone says it can't install (or update..can't remember exactly) and I select "try again" but it always fails.
[Samsung Galaxy S10+ Guides, News, & Discussion] jwarrior319:
You can downgrade since both ate bootloader v2, but it does require a factory reset. Thats why your getting the error when trying to boot. Theres too many changes from 9 to 10, so its trying to boot with leftover incompatible files on the data partition (ex. Android 10 specific system and user apps). The factory reset gets rid of that stuff.

Can anyone point me to a manual to swap my sprint G975U bloatwared ROM to G975U1?

Just check the OP. All the instructions are there
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Not exactly. The OP states that this is not a "step by step how to" for beginners. This thread assumes that the user has already done Samsung flashing before and knows exactly how to do it. For anyone who's inexperienced, they would need to visit any of the numerous "Odin flashing 101"-type threads that are here on XDA to fully familiarize themselves with the process

My carrier Unlocked Spectrum Mobile branded G975U does not have WiFi calling . Is it possible to flash different firmware and have WiFi calling as an option in the Phone settings?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
If it's not there by default, then the only thing that has seemed to work for some users is to flash U1 firmware along with the U USERDATA file of your carrier
[Samsung Galaxy S10+ Guides, News, & Discussion] d0bander:
My carrier is Straight Talk, a MVNO of TracFone I think... and these carriers can alternate and work on CDMA and GSM networks from what I've read. I couldn't find TracFone(TFN) USERDATA so I decided to try out a Sprint(SPR) USERDATA

So I did a factory reset and flashed my SG975U to XAA Unbranded U1 with a SPR USERDATA and this has successfully brought back WiFi calling and gotten rid of the Spectrum Mobile bloat.

Thank you for your help!!
[Samsung Galaxy S10+ Guides, News, & Discussion] d0bander:
After flashing my Unlocked Spectrum Mobile to U1 Unbranded with Sprint USERDATA, I decided to try this same process on my Locked, T-Mobile SG975U with my carrier SIM inserted.

After Reboot, no prompt popped up about my SIM card/Unlock Code.

Rebooted to Recovery for a Wipe and then to Bootloader.

I decided to flash a "G975U1 U2 Fix Unlock Firmware" file I found (picture attached), also with the Sprint USERDATA with my carrier sim just to see what happens.

After reboot, the first thing that pops up is "Enter network unlock code" window.

I tried to use the codes provided by the company "UnlockMonster." I was provided with four 8-digit codes (NETWORK, PROVIDER, SUBPROVIDER, DEFREEZE) and instructed to enter them in that sequence, but had no success.

The company I went through to unlock my Spectrum Mobile SG975U was UnlockPlus, and they worked just fine, providing me with a 16-digit NCK code. They also provided a 16-digit MCK code, but i don't remember having to use it.

Anyways, I am going to try to go back through UnlockPlus to request an unlock code. They claim to be able to unlock Tmobile phones but the process requires Samsung USB remote service and costs almost $150. They explain the whole Tmobile unlocking app issue briefly to explain why the price is so high. I just shot them an email as a returning customer to see if they'll do a price adjustment since I am now able to enter an unlock code.

(I apologize if this is getting off the OP topic)
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
T-Mobile stopped using unlock codes 5 or 6 years ago. Even if the firmware asks for it, there is no code that can be entered in order to successfully unlock the device.

[Samsung Galaxy S10+ Guides, News, & Discussion] Mr. Manor:
Oh ok. My apologizes i'm a newbie so please pardon my lack of knowledge and newbie questions. I did read it and downloaded the G975U_SBA_1 file. Then I downloaded the USERDATA_VZW_G975USQU1ASBA. So am I correct in using the first file in odin then when it comes to the userdata section I load the VZW userdata and run it?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
No. You can't flash zips in Odin, so the zip has to be extracted. And all files have to be flashed together, at the same time
[Samsung Galaxy S10+ Guides, News, & Discussion] Mr. Manor:
Right, I understand that. Im saying after extracting the tar.md5 files from the G975_SBA_1.zip enter those files into oden to swith the firmware from U1 to U and when it comes to the USERDATA enter the unzipped USERDATA_VZW tar.md5 file to make it a G975U VZW version?

They don't have .md5s, but yes, the rest is correct

Hi, i can flash the U1 firmware in the U version? or only change the USERDATA ATT to USC for delete bloat?. If change the userdata to USC receive update faster?
[Samsung Galaxy S10+ Guides, News, & Discussion] Ranger187:
I've had the S9+ U1 and converted it to the U and TMB, but my question is, with SamFirm, I see if I enter: SM-G975U1 and enter Region: TMB it results with:

So my question is, after I get my phone and turn it on, do all the usual, can I odin that and have a U1 with TMB, or do I need to turn the phone on and do all the blah blah, then flash it to the U firmware and add the TMB userdata?

Thanks again for providing the files!
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Yes, you can flash U1 to a U model.

I don't know what you mean by your second question.

No, changing USERDATA does not make you get updates faster.

U1 by definition has zero bloat. If you want carrier bloat and specific features, you need U1
[Samsung Galaxy S10+ Guides, News, & Discussion] Ranger187:
So with SamFirm. I can stay on the U1 with region TMB and not need to swap to U /TMB correct?

Hi not sure if this is the right place to ask sp bare with me

Haven't used Samsung phones for ages (coming from Oneplus). I live in Europe and recently bought a used S10+ Snapdragon version. I m currently checking if there is any problem with the phone in order to keep it or return it. I have some questions as i don't know much about how things work.

1. SM-G975U

Service Provider : SAOMC_SM-G975U_OYN_XAA_PP_0013

''the Serial Number''

XAA/XAA/ATT

I m assuming this is an AT&T unlocked version or am i wrong?

If yes. Does the unlocked version of AT&T comes with any AT&T bloatware? (mine comes with the normal samsung bloatware eg google services, facebook etc)

2. The last update the phone got is from May and when i try to check if there are any updates available it says '' That i have the latest update'' which i guess it is not normal. Anyone knows the reason?

3. If i update the phone through odin which firmware should i use?

Thanks for your time and thanks in advance.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
You need to use the modified Odin, check the OP. If you phone is U not U1 and no carrier bloatware something is wrong. AT&T phones have have their bloatware.

If you live in Europe why would you purchase a bootloader locked device, no matter how good a deal you got?
[Samsung Galaxy S10+ Guides, News, & Discussion] Egioni:
Well i m not sure if it is actual AT&T phone or something else. Thats what i m trying to figure out. The phone is U not U1.

I bought it because snapdragon is significantly better than exynos this year. Everything seems to work just fine. I just dont know what is the deal with the updates as i could not find any information.

I m testing the phone right now. If there is something wrong i will just return it and get my money back.
[Samsung Galaxy S10+ Guides, News, & Discussion] DWD1012:
I have this exact same issue with it not finding any updates. It doesn't even search, it immediately says there's no updates available.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
AT&T branded phones get updates with AT&T sims inserted. Unbranded (U1) get updates from the manufacturer.
[Samsung Galaxy S10+ Guides, News, & Discussion] Egioni:
Thanks a lot for your message.

So even if you buy the phone at full retail price from AT&T (without any plan or installments) and it is sim unlocked do you still get the bloatware and the update restrictions?

Sorry for the many questions i just dont know how things work in US.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
Sim unlocked is not the same as unbranded. My present device was AT&T carrier purchased. I had to convert to U1 to get OTA after sim unlock and changed carriers. Go to the OP, follow the instructions and insert your carrier's SIM.
[Samsung Galaxy S10+ Guides, News, & Discussion] jwarrior319:
Also keep in mind the US Snapdragon model might not fully support your carrier over their since its designed for US carriers. If you really want a snapdragon model i would go with the SM-G9750 which is the china/hk Snapdragon model. It is also the only Snapdragon model with an unlockable bootloader in case you want to root later on.
[Samsung Galaxy S10+ Guides, News, & Discussion] DWD1012:
Would I have to do this as well? I'm so confused. I downloaded the files, flashed it in Odin, got my AT&T back up and running, I just can't do a system update. Like it immediately tells me there's none available, it doesn't even search or take time to search. I have the G975U AT&T.
