The phone I purchased was a Sprint Locked phone. Anyway, I had it unlocked and moved to T-Mobile. We'll, I was having issues (LTE issues) and I sent it in for repair. They sent it back and it's locked to Sprint. I called Sprint and they said the MEID number shows it's unlocked. The phone says it's locked to Sprint SIMs only. With my T-Mobile SIM in it, it says "invalid SIM card"

Would it be possible to flash the U1 on the Sprint Locked phone?
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
You can flash the U1 firmware, but it will not remove the SIM lock. Sprint will have to do that, and it may need to be on their firmware to do it.
[Samsung Galaxy S10+ Guides, News, & Discussion] netengineer:
Well, I called Sprint and they said it's unlocked in their system. The problem is, the phone says it's locked to Sprint SIMs.

So how do I get it to say it's unlocked?

BTW, Tha KS for your reply. I appreciate it
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
It's possible that their unlocking process may require a Sprint SIM to be in the phone in order for their system to send the unlock command down. If you don't have access to one, I'd suggest going to a Sprint store and asking them to pop one in.
[Samsung Galaxy S10+ Guides, News, & Discussion] netengineer:
I forgot to add.... I put my phone back on Sprint with a brand new line just for that reason. So, as far as they are concerned it's unlocked.
[Samsung Galaxy S10+ Guides, News, & Discussion] nowerlater:
With your sprint sim in goto settings, update, and hit uicc unlock, should bring back down the unlock.
[Samsung Galaxy S10+ Guides, News, & Discussion] netengineer:
I did that... And I get this:

Sprint says it is unlocked in their system. I even went to the corporate Sprint store and they said their is nothing they can do because it's unlocked. View attachment 4778927

Flashing carrier locked phone?

Hi there,

What happens if you flash a different firmware onto a carrier locked phone? I know it won't carrier unlock the phone, but I presume it will not brick the phone or force it into a bootloop or anything? The reason I ask is because I just sent in an unlocked Sprint phone to Samsung for warranty repair, and they replaced the motherboard. After sending it back to me, it appears to be locked again. When I insert my T-Mobile SIM card it keeps saying that phone needs activated and the SIM is invalid. I have contacted Samsung, and they say they have no way to lock the phone once it has been unlocked, and that I have to have T-Mobile activate the SIM card on this phone, but I have never heard of such a thing. I have used dozens of SIM cards from all over the world in at least 5 different unlocked phones because I travel frequently, and this has never been an issue with an "invalid SIM". So anyway, I was curious about flashing the T-Mobile firmware and seeing if it would recognize my SIM card then. Also, the Sprint firmware does not appear to have a "network settings" page where I can manually connect to a network, but I know the unlocked and T-Mobile firmwares do.

Any advice/thoughts? Thanks!
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
Those that had their motherboards replaced, did the unit come back with the same imei?
[Samsung Galaxy S10+ Guides, News, & Discussion] netengineer:
Mine had the same IMEI according to Sprint.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
Check the imei number from the device and compare it with the original box that the phone came with.
[Samsung Galaxy S10+ Guides, News, & Discussion] netengineer:
Welcome to my world. My phone was unlocked when. I sent it in and it came back locked. I can't get the thing unlocked (the phone) Sprint says it's unlocked in their system but won't unlock. Samsung, Sprint, nor T-Mobile cn do anything about it.

I have spent hours and hours trying to get my phone unlocked but no one seems to be able to help.

---------- Post added at 08:46 PM ---------- Previous post was at 08:46 PM ----------

It's the same. I also found out they didn't replace the whole motherboard, it was just a chip.
[Samsung Galaxy S10+ Guides, News, & Discussion] Limeybastard:
Hence why I guess sprint is saying its unlocked. What a conundrum.
[Samsung Galaxy S10+ Guides, News, & Discussion] gwbyrd:
Uuuuugh... So.... I spoke to someone in the store who felt sorry for me, and he suggested I call the Sprint "International Team" that helps customers traveling overseas when they need immediate unlocks. I called them and the person I spoke to was very sympathetic and said she wanted to help me. I was on the phone with her, mostly on hold, for over 30 minutes, but at the end, she told me that they sent a "lock and unlock" command to my phone from their servers, and that I should give it 24 to 72 hours to take effect. She said I didn't have to do anything on my phone, that it would happen automatically. It's only been 5 hours, and it still hasn't unlocked, but I won't believe it until I see it! At least, I spoke to someone who seemed to believe they could unlock the phone and were willing to do so, so even if it doesn't work, I appreciated the sympathy and the effort.

Also, my phone has the same IMEI. They didn't specify exactly whether they replaced the whole motherboard or just a chip on my receipt.

---------- Post added at 10:46 PM ---------- Previous post was at 10:36 PM ----------

By the way, netengineer, the guy at the Sprint store told me that all new phones unlock automatically after 2 months? I don't want to hold onto a useless phone that long, but I was curious how long ago this happened to you? Also, have you considered a 3rd party unlocking service? They seem kind of expensive, and I don't know how legit any of them are, but seems like a last ditch possibility... If this unlock doesn't work in 72 hours, not sure what I'll do next. Sucks having an expensive paperweight. I might try to return it to the people who sold it to me, but if they won't take it, I suppose I could sell it as a Sprint locked phone to a Sprint subscriber and not take a huge loss?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
1. Sprint claiming to have unlocked the phone (but the phone showing differently) is a VERY common story. It's always the same - Sprint swears up and down that they've done it, but the phone still behaves exactly as it does when it's brand new.

2. Flashing different carrier firmware onto a locked phone isn't going to do you any good because the network unlock resides much deeper than firmware. The phone will still work the same way on the different firmware - you just won't have any cellular function.

3. The "network settings" section does exist on every single phone and firmware, but pretty much every Samsung phone now won't even display that section of the settings unless you have a valid SIM in there. For a SIM locked phone, that means it won't show up unless you have a SIM from the original carrier in there

4. Anyone tired of hassling with Sprint and needing a 3rd party solution for doing the SIM unlock can PM me

Hi iBowToAndroid, I tried reply to your private message, but nothing is showing up in my sent folder. Not sure if that's a bug... Tried various ways, so if your inbox looks spammed with a bunch of messages from me, apologies. Feel free to check and see if there are any new replies from me.

OMG, netengineer, GOOD NEWS!!! Calling the international travel department at Sprint seems to have worked!!! Miracle of miracles, my phone is unlocked and my T-Mobile SIM card is working! Private message me and I'll send you the direct number! I don't have an extension number of the person who helped me, but I have her name, if you want to try and ask for her!

iBowToAndroid, thanks for your help! Hopefully, I'm good to go now! I'm just going to flash the T-Mobile or U1 firmware and activate those extra bands! Wish me luck!

I am trying to flash from the stock rom to G975U1UES1ASDB_CL15672595_QB23514702. I know that usually the error is due to the bootloader being older or the rom being the incorrect for my phone (Galaxy S10+). I am not sure what I am missing here. Any help guiding me in the right direction would be great. Thanks!
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
Are you using the patched version of Odin? That's typically the reason why it fails besides using the wrong device files.
[Samsung Galaxy S10+ Guides, News, & Discussion] xiaoxion17:
It's the 3B patch yes. I have tried multiple versions of the U1 ROM and I'm not sure what I am missing. It's the 512Gb variant of S10+.
[Samsung Galaxy S10+ Guides, News, & Discussion] johnwayne27:
I am on VZW ASF7(i think new bootloader), will it be a while before I can flash to U1? I switched to cricket and want hotspot to work but it wont until I get U1
[Samsung Galaxy S10+ Guides, News, & Discussion] MMarshall2018:
What are the steps within Odin after the files have been downloaded? Flashing from AT&T to Verizon

Thanks!
[Samsung Galaxy S10+ Guides, News, & Discussion] mopartonyg:
You just posted all the steps, read where it says "if you are going from one carrier to another follow these steps"
[Samsung Galaxy S10+ Guides, News, & Discussion] MMarshall2018:
Thanks that is correct, but do i need to us all the files on each flash. I mean do i just use the CSC file or do i add the AP, BL, CP? Which CSC file do i use on the Unbranded? CSC regular or Home CSC?
[Samsung Galaxy S10+ Guides, News, & Discussion] MMarshall2018:
OK, so I have the Unbranded firmware installed now, but when I reflash over the the VZW firmware downloaded, it goes back to AT&T. Any chance the firmware is AT&T and not VZW? Anyway to check? Sorry for all the questions, still new at this stuff..
[Samsung Galaxy S10+ Guides, News, & Discussion] mopartonyg:
I believe you use the regular csc file not the home csc. I also think if you use an ATT sim card it will revert to ATT.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Fused = the version that you have. Binary = the version that you're trying to flash.

You're trying to go from bootloader 2 down to bootloader 1, which is a no-no. You'll have to wait for the U1 model to get its bootloader 2 update

A while, yes. Exactly how long? No one knows. Carrier (U) models typically get updated first

Proper procedure for converting carrier firmwares can be found in the OPs of my threads
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
Typically the U1 comes after all carriers upgrade. It looks like att, Verizon and TMobile have gone to V2 bl. Even once sprint pushes one, it could take a while.
[Samsung Galaxy S10+ Guides, News, & Discussion] shollywood:
Are there specific steps to go from U1 to Verizon U? Want the night mode functionality asap. Thanks in advance.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Make sure that you insert a Verizon SIM and do the "reboot to apply new carrier settings". Then boot straight to Download and flash all 5 files
[Samsung Galaxy S10+ Guides, News, & Discussion] shollywood:
It's an unlocked device and I don't have a Verizon SIM as I don't use them. Can I not still flash the firmware to gain the advantage of the night mode in the latest firmware? Thanks again
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
I don't know whether the night mode is part of the Verizon USERDATA or the base firmware. You specifically mentioned "Verizon U" so I assumed that you wanted all of their features and bloat. Without a Verizon SIM, I don't know what bloat you'll get (if any) or if Night Mode will be there. You'll have to flash and see
[Samsung Galaxy S10+ Guides, News, & Discussion] shollywood:
So just wipe it first and flash the G975U_SF6_2 files?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Don't need to wipe if you use regular CSC, since that will do it for you
[Samsung Galaxy S10+ Guides, News, & Discussion] shollywood:
Yeah great, it failed and now the phone wont even power on
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
That's basically impossible. Odin won't let you flash anything that would brick the device, due to the safeguards included. Now, if it got disconnected during flashing, that might screw things up
[Samsung Galaxy S10+ Guides, News, & Discussion] shollywood:
Yes the software (Odin) crashed (just closed), when it hadn't even been completed.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Well that's obviously not normal. Try again. If it keeps happening, then try these steps in order: a different cable, a different USB port, put the files on a different drive, restart the PC, re-download the files
[Samsung Galaxy S10+ Guides, News, & Discussion] NotATreoFan:
Hold Power + VolDown for 30 seconds. That is the key combo to simulate a battery pull on newer Samsung devices. If that works, you can go back into Download mode and flash again.
[Samsung Galaxy S10+ Guides, News, & Discussion] shollywood:
I'd love to but the phone will not even power on. It's not doing anything. It crashed twice and now it's done. Tried hard reset everything...no bueno
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
It has to at least charge. And for most later model devices, if flashing got interrupted, it'll automatically go to a teal-colored error screen when you plug it in via USB
[Samsung Galaxy S10+ Guides, News, & Discussion] shollywood:
It did that, phone was 100% charged. Then screen shut off and cannot be powered back on. Had the exclamation mark and telling me to use emergency recovery in Samsung Switch. That too would not work. Now NADDA
[Samsung Galaxy S10+ Guides, News, & Discussion] dinopeyton:
I had the same issue. try Odin from that point,should install. worked for me

ASF6 Odin files is corrupt. Something is up with the AP file. No one has been able to successfully flash it
[Samsung Galaxy S10+ Guides, News, & Discussion] innocentone1:
Do you think this build would work on tmobile? Would this mess up our ability to OTA? Also who did you pay? I need to pay this guy lol.
[Samsung Galaxy S10+ Guides, News, & Discussion] Wacky2bakky:
Well ASF7 was Tmobiles OTA not ASF6 so yeah, it would throw your OTAs off. It will work on a Tmobile phone yes. In the future if there was to be a newer Tmobile ota, u would just have to manually flash back to the previous Tmobile OTA and update OTA that way. I got them off the GSM2File website. They get Odin firmware files early before their released by Samsung on Samfirm. If u donate a couple dollars my way, I will be more then happy to share with u the correct Odin files for build ASF6.

I have a question and I really hope one of you genuine firmware geniuses can help me. I have a brand new S10+ (Xfinity Mobile unlocked). For awhile i was using Metro by T-Mobile service so in the past I have flashed my Note8 (Verizon unlocked) & my current Note9 (Xfinity Mobile unlocked) both to U1 US unlocked firmwares and been quite happy with these firmwares on Metro by T-Mobile. About a week ago I changed my service and got a business line with AT&T (postpaid). Now that I am with AT&T I would like to use all the benefits of AT&T service on my S10+. I have flashed onto my S10+.

Base: G975USQS2ASF7

Build: PPR1.180610.011.G975USQS2ASF7

So far wifi calling does not work but I might have to call AT&T to get it working? Also people have gotten the recent update with Night shot and it says my software is up to date. Will I be getting updates with this firmware? Also noticed that with my sim in my S10+ the 5Ge signal is VERY strong. When I run speed test in my house at the dinner table I ran a speed test 3x and got a average of 110up & 11down with my AT&T sim in my S10+. When I switch my sim back to my Note9 with U1 US unlocked firmware I did the same test 3x in the same exact spot and got a average speed of 30up & a inconsistent up speed of 20/.13/3. I would just like to have the current firmware on my S10+ for my AT&T sim as I am looking to use my S10+ full-time now. Any help is appreciated.
[Samsung Galaxy S10+ Guides, News, & Discussion] innocentone1:

[Samsung Galaxy S10+ Guides, News, & Discussion] johnwayne27:
No one seems to have a straight answer. Im guessing if you flash the 4 files without the home csc that it will take you to asf6 due to it being the same bootloader.

I have never flashed a phone before so bare with me....

I just bought a Galaxy S10 Plus Snapdragon from somebody and it ended up having AT&T's Firmware... I have service with Verizon and when i put my sim card in it worked, but of course i couldn't send pictures and do a couple other things through the android stock messaging app!... I wanted to flash the U1 on this phone but idk which file is the correct one... i also don't wanna mess anything up... I did try it but i got an error saying Sha256 and it didn't go any further... so i didn't bother going any further... Is there a step by step guide? Please help!!!
[Samsung Galaxy S10+ Guides, News, & Discussion] todd3835:
If you just don't flash any CSC, it shouldn't wipe, but may mess up your OTAs in the future. Or you could just wipe.

To swap carriers, you need to flash U1, then back to U. I don't know if there's a V2 bootloader for U1 yet. If not and your already on V2, your stuck until it's out.

Hey guys,

I got an SM-G975U with AT&T Unlocked off of eBay that is boot-looping like crazy and I was hoping that properly flashing another firmware on it would help. My carrier is T-Mobile, and inserting my SIM into the phone has worked up until it started boot-looping.

In terms of flashing it, can I just use ODIN directly with the firmware G975USQS2ASF7 from SamMobile? It seems like that's the latest firmware available for T-Mobile. Or do I have to flash the U1 firmware first, and if so, does it matter which one?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Nope. If the phone isn't doing the switch automatically when you insert your desired SIM, then you need to have U1 firmware in order to do the conversion properly

If it currently has AT&T firmware, and has not done the firmware conversion automatically via the SIM, then you can't just flash a T-Mobile build and get T-Mobile bloat and features. You need to go to U1 first
[Samsung Galaxy S10+ Guides, News, & Discussion] trannick95:
Is there a specific version of U1 that I need to flash to first? Or will any U1 version do, and then I can flash to a specific T-Mo firmware that I want?
[Samsung Galaxy S10+ Guides, News, & Discussion] mystikal87:
I'm new to the S10+ scene as I recently got a T-Mob branded. I've flashed the U1 unbranded using the modded Odin, however, I get an error when the phone restarts:

EDIT: My BL was already on v. 2. Now I gotta wait for U1 to get to v. 2.
