I wish I knew, Samsung wants me to send it in to them so they can test it. Which means I will be without a phone.
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
For those on ATT, the latest official version is ASD9. My mom and I both got it today.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
Just do it.
[Samsung Galaxy S10+ Guides, News, & Discussion] nugzo:
where do you find the build date?
[Samsung Galaxy S10+ Guides, News, & Discussion] netengineer:
Used the app called "Phone Info"
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
The signal has been a general issue for me too since the beginning. Speeds improved with the U1 firmware, but I still drop signal so much easier than my Note 9 or S9+ before that did.

I'm very close to trying the OnePlus 7 Pro and seeing if the signal grass is any greener.
[Samsung Galaxy S10+ Guides, News, & Discussion] dhart62:
I apologize if I missed the answer to my question in the previous pages. I have a sm-g975u vzw unlocked but it Is locked to at&t. My note 8 crashed and I was given this phone. I have tmo network but I don't understand what's up with the lock, could anyone shed some light on this for me. I would like to flash this device with this firmware but again confused.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
I'm confused too. If you're speaking in terms of the SIM slot, a phone can't be both unlocked and locked at the same time. It also can't relock after it's been unlocked - a SIM unlock is always permanent
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
If the phone was originally purchased from Verizon, it would have been SIM locked to them, under a new policy that just started with the 2018 iPhone models. The only requirement to unlock it for other carriers is to keep it active on Verizon for 24-72 hours, and it happens automatically.

The firmware is different than SIM lock, and it sounds like the former user flashed ATT firmware to the phone. And that you have T-Mobile, and want to use it without ATT apps.

If I got that right, then all you need to do is download and flash the latest TMO firmware from Post #2, and use Odin to convert it.
[Samsung Galaxy S10+ Guides, News, & Discussion] dhart62:
That's what I was thinking. Maybe bought from vzw but even after 60 waiting period then flashed with straight att csc. Though with my sim it is saying invalid sim card: network locked sim card inserted. Attached is 1 dev info from a imei check site and a couple of screenshots of dev check info. If this question needs to be moved to another thread or location so the OP is not cluttered, I would greatly appreciate the assistance.
[Samsung Galaxy S10+ Guides, News, & Discussion] dhart62:
Really, I guess I could try and worst case scenario we find out how to boot EDL mode lol
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Check under About Device on the phone, and see what is listed for CSC. The last section is what we care about most, because that will indicate the carrier the phone was originally used for.

For example: a phone bought from T-Mobile will look like TMB/TMB/TMB

If the last one for you says ATT, that means the phone was oringally carrier locked to them.
[Samsung Galaxy S10+ Guides, News, & Discussion] dhart62:
I checked that. It is ATT/ATT/ATT. I was just confused why some was saying vzw unlocked and hoped I could just flash it. I've been using my son's j3 prime for over a week and let me tell ya, it's no note 8 or s10+ for that matter lol. This device is nice even if I've only been on wifi. I have metro by tmo and they assigned my sim to it but with it being locked......
[Samsung Galaxy S10+ Guides, News, & Discussion] Ijaz Farooq:
Can I flash U1 firmware on my G975W Snapdragon variant?
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
I would remove the pictures showing your IMEI number. I've seen other posts saying people can do bad things if they have your IMEI.
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Yeah, that's definitely an ATT phone, and the message indicates it's SIM locked to their network. If there's no balance on it, you can ask them to unlock it, but they will most likely require it to be active on their network first.
[Samsung Galaxy S10+ Guides, News, & Discussion] nugzo:
Dont know where that last screenshot showing verizon/unlocked came from but it is wrong. Like [MENTION=320479]NotATreoFan[/MENTION] said, it's an ATT phone. If it were a Verizon phone you wouldn't have any issues. You'd also see it listed as ATT/ATT/VZW instead of ATT/ATT/ATT. The last one cant be changed, it tells you what carrier it was sold as.. From what I understand Verizon phones haven't been sim locked for many years. At least the Android phones haven't. I've used ATT sims in a couple of different older verizon phones. The s5 and Note 5 and they just worked. I've Also used s8 , s9 and note 8 with ATT sim without issue. I say without issue but i've always installed ATT Firmware on them before used as a daily driver. After that they've all worked like they wore made for my carrier. No other carrier besides Verizon does that. You have to jump through hoops and meet their stringent rules before they would allow them to be unlocked. You can try one of the pay unlocking services..
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
It is possible that AT&T did a staggered roll out of the OTA. You could also flash it manually from recovery, but since it's now running ATT firmware, it will trigger a factory reset.
[Samsung Galaxy S10+ Guides, News, & Discussion] kcsevo:
This U1 firmware is dam smooth! Thank God TMO and U1 are on the same firmware. I was able to get RCS messaging and video calling by flashing tmo userdata and CP file.
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
If you flash the TMO userdata file, don't you just end up with TMO firmware and their normal apps? Genuinely curious on this one.
[Samsung Galaxy S10+ Guides, News, & Discussion] kcsevo:
Not at all. All it does is add the RCS and wifi calling. I use to do it with my s8+. The only thing is you won't be getting any updates. You would have to manually do them each time. I dont have any tmo bloat. Very smooth!
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Awesome to know! My phone has been flawless so far, but if I ever need to reset, I'll cover in the same way.
[Samsung Galaxy S10+ Guides, News, & Discussion] S10Plus:
So, I just flashed the Tmobile firmware but I am still getting everything from verizon...splash screen, bloatware, etc. I left the tmobile sim card in during the new firmware install. Do I need to factory reset the device again?

EDIT: I factory reset it again but it's still verizon?

Do I need to factory reset it BEFORE I do the firmware?
[Samsung Galaxy S10+ Guides, News, & Discussion] TechSilver13:
If you are using a version SIM card I don't think that's preventable but I could be wrong.
[Samsung Galaxy S10+ Guides, News, & Discussion] S10Plus:
I have the tmobile sim card in. I am doing the whole thing over again, factory reset, firmware and then we'll see.

EDIT: I did a factory reset with my tmobile sim in and flashed the tmobile firmware and still get the verizon splash screen, bloatware, etc. Am I doing something wrong?

---------- Post added at 01:45 AM ---------- Previous post was at 01:19 AM ----------

I did the U1 firmware and phone started back up, and said lets get started and the message to restart with new sim, blah blah and no more verizon splash screen!

---------- Post added at 01:54 AM ---------- Previous post was at 01:45 AM ----------

So everything is good. I have all of the Tmobile bands now instead of Verizon. I don't have the Tmobile splash screen since I did the UI but i am fine with that. It's just the regular Samsung screen. I have wifi calling but I am missing HD and Video calling....is there any way to get that back? Thanks for all of the help.
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Did you make sure to flash the TMO CSC (not CSC Home) and TMO Userdata? That should be all it takes to convert over to a different carrier.
[Samsung Galaxy S10+ Guides, News, & Discussion] S10Plus:
Correct. I did it 3 times.

I did the U1 firmware and it worked fine. I then flashed the userdata and CP for TMO afterwards.

---------- Post added at 03:22 AM ---------- Previous post was at 03:13 AM ----------

Also, for software updates I get the following: "Your current software version isn't supported. Visit a service center"

How can I do my updates?
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
That error message is likely due to mixing TMO and U1 firmware. You will most likely need to sideload future updates.
[Samsung Galaxy S10+ Guides, News, & Discussion] kcsevo:
That's the same messages I have and I mixed the firmware just you said!
[Samsung Galaxy S10+ Guides, News, & Discussion] S10Plus:
Thanks. So, I think my last question...How do I load the updates since they are not OTA?
[Samsung Galaxy S10+ Guides, News, & Discussion] kcsevo:
I actually would like to know this to. I just usually reflash everything and that takes for ever
[Samsung Galaxy S10+ Guides, News, & Discussion] miguelmedina1993:
Can you show me how you do that?

---------- Post added at 05:42 PM ---------- Previous post was at 05:40 PM ----------

So I bought the Verizon Galaxy S10+, I have an AT&T sim card installed, will I get OTA updates if I flashed the US unlocked firmware?
[Samsung Galaxy S10+ Guides, News, & Discussion] jeffyv2:
When it gets uploaded here or wherever you just Odin the new version..

Sent from my SM-G975U
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Since you modified your system partition by adding TMO files, standard OTAs released for U1 will not work. You will need to upgrade using Odin each time.

If you flash the U1 firmware, you will get OTAs whenever Samsung releases them for U1, which is typically quarterly. However, if you flash the ATT userdata (once available), then you would need to use Odin like above.
[Samsung Galaxy S10+ Guides, News, & Discussion] S10Plus:
So whenever I have done the firmware upgrade on the S10+, It wipes the phone. So, I'll have to reset the phone up every time there is a new firmware....ay yi yi.
[Samsung Galaxy S10+ Guides, News, & Discussion] miguelmedina1993:
Thanks man

I rather just have the unlocked firmware since I'm going to be staying with AT&t
[Samsung Galaxy S10+ Guides, News, & Discussion] watchnj:
sorry new to this, Do I need to check BL+AP+CP+CSC+USERDATA to fully convert by unlocked to a TMO ?
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Verizon began SIM locking their phones last fall with the release of 2018 iPhones. But they automatically unlock within 72 hours. It was done because their stores were being targeted more than others for theft since the phones could be sent overseas without having to mess with carrier locks.

Eventually they will require 6 months use to qualify for unlock, but I don't believe they've stated a date for when that will begin.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
Would you know why Verizon's sim unlock policy is different to the other 3 ? It seems way more relaxed. Cheers
[Samsung Galaxy S10+ Guides, News, & Discussion] dhart62:
What's crazy is the last screenshot was from a site for checking imei. I have now gone back to several imei check sites that all said vzw unlocked, now they all say at&t. I had been checking a few days now and was seeing the vzw message along with crap like: the device is white (it's not), the device is 5g (I'm not sure if they've released those yet) the sites that didn't have the vzw message just said they didn't know what kind of device it was. I was almost ready to see if the tempered glass would really stop a bullet Lol.
[Samsung Galaxy S10+ Guides, News, & Discussion] nugzo:
Maybe Verizon should update their official Sim lock/unlock policy. I found some info about what you were talking about in other articles, but nothing directly from Verizon. From what I've read elsewhere I believe what you said to be true. It seems theft is the main reason behind it. If Verizon is worried about theft why not blacklist a stolen phone. I'm sure they have the ability to do that. Or like Boost Mobile phones, they wont work at all until activated at register when purchasing. I found that out by buying an LG that was new in the box from someone off the street. It was unopened with the cellophane still on it. I Tried to put a friends Boost sim card in it and it wouldn't work. I called boost and they said i needed to take it back to the place of purchase because it wasn't activated at the register. I imagine it's done similar to the pre paid $25, $50 gift cards that you see laying around in stores everywhere. They aren't worth a penny until activated at the register. I know i'm looking for a hard way for verizon to fix a problem that they have an easy fix for already, which is lock them like other carriers. Verizon might be doing something illegal by locking them though, It seems they have an agreement with the FCC about their phones and why they are unlocked to start with. The deal with the FCC (Federal Communications Commission) requiring it to unlock phones as part of its acquisition of the "C block" of 700 megahertz spectrum, which powers its 4G LTE network. One section of the deal specifically prohibits Verizon from configuring handsets to prevent them from working on other networks. Here is Verizons current unlock policy at their website https://www.verizon.com/about/consumer-safety/device-unlocking-policy
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
It started with the 700MHz spectrum auction in 20xx. The FCC added language to the auction terms that barred locking devices using the new spectrum. Both ATT and VZW purchased the spectrum, but only VZW adhered to the rules. ATT locked their devices before the auction, and kept doing so after. Verizon was CDMA only prior, so SIM locking wasn't a thing for them before.

The recent change happened due to the earlier mentioned targeting for theft. It happened to VZW more because ATT/TMO carry GSM-only iPhone models, whereas VZW carries the global models that work with literally any carrier across the world. Although it's technically still against the rules of 700MHz spectrum, given what's been happening, I don't blame them for locking devices down.
[Samsung Galaxy S10+ Guides, News, & Discussion] WhoIsJohnGalt1979:
The signal strength was so inconsistent with U firmware on VZW. Almost a consistent one signal bar except for when you are on the road. Out of curiosity,.I flashed the U1 firmware. I have been getting constant 5 bars in the same place where I used to get 1 bar signal strength and speed test gives me 30 mbps inside the apartment. Wireless calling and native spam protection work just fine. Guess there is no option to enable HD+ during phone calls or native video calling. But am better off to live without those two features while I get more consistent signal strength.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
That's pretty strange regarding the bars on the status bar. Since U1 models shows bars conservatory compared to U models in my experience. By the way, thanks for the Verizon unlocking back story.
[Samsung Galaxy S10+ Guides, News, & Discussion] WhoIsJohnGalt1979:
Totally agree with you. Carrier aggregation always gives better signal strength leading to U firmware giving better signal strength than U1 firmware. But strange enough I get exceedingly better and consistent signal strength on the U1 firmware.
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Starting with Pie, you cannot trust signal bars the same as Oreo and prior. Google now allows carriers to determine how the dBm reading translates to bars shown. This was done because theoretically LTE w/ -100dBm will still be more reliable than HSPA w/ -85dBm.

I'm currently sitting in an area with -112dBm on my OnePlus 7 Pro. It shows half strength signal, but still pulls over 50mbps.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
I'm fully aware about bars on status bar being inaccurate. My point was that the carrier versions falsely tend to show "more bars" in the status bar. Than the U1 models.
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Yeah, which makes sense since U firmware has userdata from the carriers and that's likely where they have the code determining the signal indicators.

Install G975U1UEU1ASD8 without wipe?

hello guys and girls, I need some help on how exactly to do this. I have a S10+ SM-G975U1 and used the SG-G975U (ATT G975USQU1ASBA) and I want to update it to the latest one available right now G975U1UEU1ASD8 but I don't want reinstall all apps and configurations again. How can I do it? I already downloaded the G975U1UEU1ASD8 zip but I don't know If I need something else.

Please let me know the right steps to follow to achieve what I want.

I will appreciate it.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
What do you mean "used the SG-G975U (ATT G975USQU1ASBA)" ?? Does your device currently have U firmware, or U1? If it has U, you can't flash U1 without doing a factory reset
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
If you currently have U firmware, there is no path to U1 that does not require a factory reset. You can use SmartSwitch to minimize the pain, but there's no way to avoid it.
[Samsung Galaxy S10+ Guides, News, & Discussion] juannicolas:
No my friend, I'm running U1
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
That's not U1. That's the bootloader version, which for the S10 is still on version 1. You have G975U in the beginning, not G975U1. You have ATT branded U firmware, and will need to factory reset in order to convert back to U1.
[Samsung Galaxy S10+ Guides, News, & Discussion] juannicolas:
Thank you, now I get it.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:

Samsung s10 plus tmobile to sprint help

Hello i have a samsung s10 plus tmobile. I flash to u1 already then flash sprint firmware but my phone won't active with sprint getting error 407 . need some help please
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Did you SIM unlock it first? And did you check with Sprint to see if they will accept that device on their network?
[Samsung Galaxy S10+ Guides, News, & Discussion] os49ers760:
Yes its sim unlock , i haven't check but it does work for 5 min then I get a message your sim card is locked
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Well you usually can't activate a new device on Sprint just by inserting the SIM. You have to contact them every time that you want to change phones because they have to activate it in the system
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
You need to call them. Unlike Verizon, Sprint still uses CDMA for provisioning devices. SIM is used primarily for LTE data.
[Samsung Galaxy S10+ Guides, News, & Discussion] whelmar:
Silly question, but I'm going to ask it here...

Do you thing that Samsung will eventually make the SM-G975U version of the software carrier agnostic like previous versions of galaxy line... meaning it'll just re-brand depending on the sim inserted if the phone is unlocked....
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
The phone should already be doing that. It's been like that since the S7
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
For the Note 8 and Note 9 series it wasn't until later firmware updates that brand switching was available / implemented.

This is probably why Sprint doesn't accept unlocked U models from T Mobile or ATT on their network yet. Since the firmware doesn't switch.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
It has nothing to do with the firmware. It's about whether Sprint has the IMEI whitelisted in their database. Whether they'll accept the IMEI on their network has nothing to do with which firmware version the phone has.

www.sprint.com/byod
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
The firmware of "U" models from Samsung in the past Note 9 , Note 8 , S9 etc were not self branding / auto carrier firmware switching out of the box. After a few firmware updates this ability was present.

In regards to Sprint, they won't whitelist a carrier unlocked "U" model on their network until Samsung has the relevant self branding auto firmware in place which I don't believe the s10+ has now. Simple to prove, insert a another carriers sim card into a unlocked T Mobile or ATT device and check.

I remember my T Mobile branded Note 8 which was sim unlocked didnt auto switch firmware until Samsung released the relevant firmware. And it was also until that point Sprint wouldn't whitelist my T Mobile IMEI for use on their network.

Check that sprint BOYD database once Samung releases a firmware that allows auto branding, you'll see.
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
I think he's referring to the BYOD firmware. On the S9/+ that was when the "B" firmware came out. It meant you didn't have to swap to U1 and back to U to swap carriers.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
Yep, the yank network providers call it "BOYD" . Comical [emoji6] its basically sticking your effin sim in an unlocked U device and the firmware switches.

[Samsung Galaxy S10+ Guides, News, & Discussion] Psyscope:

[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
ATT has a history of not allowing carrier features on phones not purchased from them. The forums are littered with reports of flashing the U to get those features and they don't work.

If you did purchase yours from ATT directly, and flashed to U1 and wish to go back, then yes, that will bring back those features, just make sure to flash U with the sim installed, and flash the att userdata.

There was someone here on the forums that claimed to have managed to flash U1 with parts of U that managed to get U1 updates with ATT carrier features, but it was with mixed files between U and U1 with steps involved.

You can flash U1 regardless. It doesn't even need to be unlocked.

You can't flash any 975 firmware to a 973. I'd try the Frija tool to get the right firmware.

The other thing is you need to flash to U1 and then back to U for carrier swap if you want all features.
