You can't update because your Baseband doesn't match the Build, probably because you (or someone else) had a SIM unlock or something similar done to it, and they had to downgrade the Baseband. OTAs should work fine if you can get your hands on the SIV baseband (CP Odin file) and flash just that. Otherwise if you want to do the full flash, you can flash any bootloader 2, 3, or 4 version of either U or U1 firmware
[Samsung Galaxy S10+ Guides, News, & Discussion] Rizun:
I see. I think i'll do full flash instead. Will my sim stay unlocked if i do that ? Thanks for responding
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
Go to settings and verify that you are on U1 in about phone.
[Samsung Galaxy S10+ Guides, News, & Discussion] Rizun:
My bad, i was wrong it isnt u1

---------- Post added at 05:14 PM ---------- Previous post was at 04:52 PM ----------

But I checked Frija and can only find Fw for U1 for this phone's CSC, or that actually doesnt matter ?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
If the unlock was done correctly by a true professional, then yes. But the problem is that there are many amateurs out there who think that they know how to do it and truly do not, or they only do a temporary unlock and don't tell you
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
If you bought the phone from a legitimate source then you should be able to ask for the sim unlock code. If it's still associated with the original carrier you will have to contact them and negotiate with them for the code.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Only half of the US carriers who sell this model use unlock codes - the other half don't. So SIM unlocking one isn't always as easy as a simple little code
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
My error. The major carriers I have purchased from do.
[Samsung Galaxy S10+ Guides, News, & Discussion] Rizun:
Thats a bit dangerous then. I dont really know about Sim locks from provider, because in my country they only sell unlocked phones. The csc on my phone is XAA tho, or that can be changed too ? Thanks
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
The CSC is determined by the firmware that you flash. So yes, technically, it can be changed
[Samsung Galaxy S10+ Guides, News, & Discussion] Rizun:
Alright then. I think i'll research a bit more before flashing. Thanks

Hard Bricked my SM-G975U At&t unlocked

Where did I go wrong, I have read so much about the instruction and visited multiple forum. I'll list exactly what I did and maybe someone can tell me where it went wrong.

I have a at&t unlocked Galaxy S10+ model reads SM-G975U. I read that in order to change from At&t firm to Spectrum I would first need to flash to U1 so here are the files I downloaded from samfirm. SM-G975U1_G975U1UES4DTG1_Q(Android 10)_XAA_Factory Rom (5 File)_20200806. I also used Odin3 3.14.1_3B_PatcheD. Downloaded Samsung_USB_Driver_v1.7.23. I had installed Smart switch to backup my phone prior to flashing.

1. Backed up using Smart Switch.

2. Reset the phone to factory and turned it off

3. installed Samsung usb driver

4. opend up odin3 PatcheD. I didn't right click and run in admin mode if that was the mistake.

5. Put BL,AP,CP,CSC (BL_G975U1UES4DTG1_CL18725736_QB33049299_REV00_user_low_ship_MULTI_CERT.tar.md5 / AP_G975U1UES4DTG1_CL18725736_QB33049299_REV00_user_low_ship_MULTI_CERT_meta_OS10.tar.md5 / CP_G975U1UES4DTG1_CP16346744_CL18725736_QB33049299_REV00_user_low_ship_MULTI_CERT.tar.md5 / CSC_OMC_OYM_G975U1OYM4DTG1_CL18725736_QB33049299_REV00_user_low_ship_MULTI_CERT.tar.md5)

6. put the phone in the download mode. (hold volume down and bixby and insert the usb) I don't remember correctly if I had the phone plugged in download mode before inserting the files.)

7. Press start. (it took a just a second and it came back failed error. I remember from a youtube video that I have to restart the phone back into download mode again so turned it off and reput back into download mode.

8. This time it took maybe 20sec +, - and came back failed but now the phone screen came with emergency recover mode.

9. I panic and do google search and found some old thread about using Smart Switch to fix the firmware so I try but the phone does not show up. I tried reinstalling the usb driver inside Smart Switch option.

10. Nothing I did would reconize the phone when I plug it in. I ended up thinking it's going to drain the battery so I should turn it off and try again later.

11. Held volume down and bixby and the screen went blank. I tried to turn it back on but nothing. At this point I knew the phone is dead. Tried every combination I can think of on the buttons. Nothing helps.

12. I took the back cover off and figured maybe I should unplug the battery and try and see if I can get back into download mode but nothing still. I can feel the processor area getting hot so I know it's running but the screen is completly blank.

13. I ordered me a SM-G975U1 from ebay that has cracked front and back screen. I'll just use the motherboard off that broken phone and try again. But I need to know where I went wrong so I don't make the same mistake.

All of this because I use At&t phone on Spectrum and it would not let me use visual voicemail and the text messaging would not send and pictures. Please advise what steps I should take on this time. It was a costly mistake if I made one. BTW I want to be on Cha rom with spectrum blotware.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
We would need to know exactly what errors appeared in Odin and on the phone, in order to know what went wrong

Hasn't been released for US models yet
[Samsung Galaxy S10+ Guides, News, & Discussion] Dr3dav3:
Hello everyone, please help a noob. I just got a G975U that still runs on android 9 and when I try to download updates OTA, it says that my device software is up to date even though there is a "Mon, 03 Aug 2020 12:10:06 +0000" release on Sammobile.

How do I go about downloading and installing the update myself without possibly bricking my device?

I have basic knowledge and experience using Odin. Thanks in anticipation.?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
I would highly recommend reading at least one of the "beginner's guide to Odin flashing"-type threads that can be found here on XDA
[Samsung Galaxy S10+ Guides, News, & Discussion] Dr3dav3:
I've read that years back and I still read it before I do anything with odin.

Should I just go ahead and flash the update from sammobile?

Is it safe? I dunno if this device is an unlocked version or if it came unlocked directly from Samsung. Is there a way to find out?

So sorry if I'm being a bother.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
1. You can flash any version that is from the device's current bootloader level, or higher

2. Extensive discussion has been made in the OP and the thread about where the best place to get firmware from - and it's NOT SamMobile.

3. The difference between carrier models and Samsung models is already stated in the OP.

already reflash SM-G975U1..so i can flash XAA firmware..

---------- Post added at 03:43 AM ---------- Previous post was at 03:34 AM ----------

You can't flash *just* USERDATA and have anything change. Also, USERDATA and CSC are *not* the same files - extract them and you'll see.
[Samsung Galaxy S10+ Guides, News, & Discussion] awireless:
So how do i use it to convert say a att to Verizon? do i flash Verizon 4 firmware with the Verizon userdata? or is the 4 file the same for every carrier and the usersata just determines what carrier it goes to?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
The 4 files are the same, for every carrier. USERDATA contains the bloat.

Instructions for converting were given earlier in the thread

ASC8 update is live for Sprint users.
[Samsung Galaxy S10+ Guides, News, & Discussion] steve_xyz:
So if I want to flash my ATT S10+ to U1 firmware, then I just need to do step 1: Wipe in recovery -->reboot bootloader-->flash U1 firmware with non HOME CSC. That's it?

And if I want to flash back to ATT firmware (from U1), then I need to:

1) wipe in recovery

2) reboot with my ATT sim inserted, let it apply new carrier settings.

3) reboot to bootloader, flash U firmware with non HOME CSC and ATT USERDATA.

Is that correct? Thanks!
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Yes. But for flashing back to U, you can skip step 2. It'll do that reboot the first time it boots up with U1 and you'll never see it again
[Samsung Galaxy S10+ Guides, News, & Discussion] steve_xyz:
Great! Thanks! One more question: which Odin version should I use? I remember couple years ago when I converted the S8, I needed to use Prince Comsy version to flash the U1 firmware, and then edit the ini file of the regular version to flash back to the U firmware.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:

does any one know if the unlocked phones from samsung are software locked at first? after having my s10+ for a week I flashed it to verizon firmware, today my 11yr old daughters 10+ came in and I had got her a unlocked laso, I tried to flash the verizon firmare before setting it up an it wont do it, its flashes but when it starts its still the same unlocked firmware, I tried it twice...
[Samsung Galaxy S10+ Guides, News, & Discussion] rtarv321:
I think I remember reading in this thread a couple of weeks ago that Samsung locked it for 24-48 hours?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
There is no such thing as "software locked". The reason that it's not converting is because you didn't set it up first. You need to do the same thing that you did previously (the same steps are also given earlier in this same thread)

Upgrade ATT from SAT to SBA

Thanks for posting the SBA ATT USERDATA.

I'm currently running SAT with the ATT USERDATA.

Using Odin if I flash to SBA using the Home CSC it should leave all data/settings/etc intact, correct, just like an OTA?

Thanks
[Samsung Galaxy S10+ Guides, News, & Discussion] gizzyman:
well there is something going on, I have the phone all setup and tried to flash it again and it still will not be verizon when it reboots, its exactly the same. maybe I will have to wait a week like my s10..I just know something is wacky with this. it flashes fine, reboots fine, but it reboots to exactly like it was when I got it.

I'm using a U1 in Mexico with a service plan and sim card from Telcel. Fortunately, LTE, VoLTE and WiFi Calling are all enabled. Unfortunately, the Spam Protection and Smart Call feature toggle is disabled and set to No. I would like to have this option enabled. Do any of these firmware have this option enabled?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Yep

Like I said before, you need to do the same thing that you did previously (the same steps are also given earlier in this same thread)

Even if they did, the features wouldn't work unless the carrier and the firmware matched
[Samsung Galaxy S10+ Guides, News, & Discussion] neonarc:
That maybe but I'd like to try. If VoLTE is working with US unlocked firmware, I have hope Smart Call will too if the option toggle is enabled. I just need to know which U carrier firmware has it enabled, please.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
They ALL have it enabled. But it doesn't work unless the SIM matches the firmware. So it doesn't matter which one you flash - none of them will work for you, since you're not in the US.
[Samsung Galaxy S10+ Guides, News, & Discussion] :
There a guide anywhere to flashing a different carrier's OS to my S10+? I have an ATT variant but use T-Mobile.

Also, does this void warranty? And does ATT need to unlock phone first?
[Samsung Galaxy S10+ Guides, News, & Discussion] Dr3dav3:
1. Okay. Very much helpful.

2. Please point me in the right direction??. I've been searching the web about this but I might be inputting the wrong search parameters.

3. I understand that the G975U is the US version. Unless I'm wrong, I deduce that I can flash any G975U firmware that doesn't have a carrier tag. Please correct me if I'm wrong.

Thank you so so so very much for your patience.??
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
The answers to these are already found in the OP.

1. SamFirm and Frija don't require very many search parameters

2. You can flash any G975U firmware, carrier tag or not
[Samsung Galaxy S10+ Guides, News, & Discussion] Dr3dav3:
Thank you very much. I've gotten pretty much everything. But do I need to have my bootloader unlocked? And if yes, how do I even do that? I've been searching for over 6 nonstop hours now, nothihg.
[Samsung Galaxy S10+ Guides, News, & Discussion] AzN_NiNjA01:
My phone will not turn on nor able to be reconized by the computer anymore. When my new one comes in I guess I'll keep your suggestion in mind.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
*facepalm*

Don't you think that if that was a requirement, it would be mentioned in the OP...? USA Samsung models haven't been bootloader unlockable since the S6's
[Samsung Galaxy S10+ Guides, News, & Discussion] Dr3dav3:
*Grin*?

I'm so sorry. But I really appreciate your patience. I'm awed?. I'm just trying to be careful.

I currently own a sm-g975u with what seems to be ATT/XAA branded firmware. I bought this device outside of the US so unfortunately I do not receive OTA updates and am stuck on a firmware from January (CTA2). Can I directly flash the latest USC firmware on my device without any additional steps or negative consequences?

The device is unlocked and I am using it without any problems but would love to update. Would appreciate it if someone could point me in the right direction.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
There's no reason for you to be using US Cellular firmware, if you're not even in the US. But that's what you want to flash, yeah, you can

Things like wifi calling or OTA updates may not work if USERDATA wasn't flashed. You'll have to watch it and see what happens
[Samsung Galaxy S10+ Guides, News, & Discussion] Khalid41011:
Thank you for the help. I will flash g975u1 if I fail to receive OTA updates. Will see how it goes with this one. If I do so, should I flash XAA region and will I have to factory reset or can I just dirty flash ?

You can never dirty flash going between U and U1. Factory reset is always required
[Samsung Galaxy S10+ Guides, News, & Discussion] mendeln:
So I flashed my phone from G975U1 to G975U yesterday, first time, held my breath for a while but all seems fine now, but I have some questions so I know for the future.

My phone was already on bootloader 4 and as I understand you cannot flash to an older bootloader version so I found these files here: https://androidfilehost.com/?fid=8889791610682905278

I'm on AT&T (and I was doing this because I wanted WiFi calling), but this zip file doesn't have a ATT USERDATA file. Could I have used the TMB userdata file? or should I have used an older version ATT userdata file from here https://androidfilehost.com/?w=files&flid=306518 (which is from an older version).

I wasn't sure so I decided to just skip the USERDATA file, I first wiped the phone, ran Odin (version 3.13.1), completed successfully, phone rebooted into the recovery screen with an error on the bottom of the screen

'unable to disable quotas on /dev/block/bootdevice/by-name/userdata because /system/bin/tune2fs is missing.

(After recovering from my first heart attack), the recovery screen first choice was to reboot device, I did that and it came back to the recovery screen with an error which I forgot to record exactly, but it said it could not load something or other (possibly userdata, but not sure). the error suggested to wipe the... (sorry I don't remember exactly which thing it suggested to wipe). but I did that and rebooted again and it came up with the samsung logo followed by the AT&T logo (sat on that for a good few minutes, gave me another heart attack, but eventually moved on) and now all seems to be working. (if I boot to the recovery menu again it still has the tune2fs missing error, but a normal boot goes smoothly and everything seems ok).

So bottom line: In case I ever have to do this again, what SHOULD I have done with regards to the USERDATA file, a: use the older ATT version, b: use the TMB version included with the other files, or c: nothing (as I ended up doing).

Thanks.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
d: wait until an ATT USERDATA from your current bootloader level is made available
[Samsung Galaxy S10+ Guides, News, & Discussion] mendeln:
Thanks, so now that I already did it.

Is the tune2fs error is related to my skipping the USERDATA file?

Is there anything I should do now to 'fix' my phone which seems to be working just fine?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
1. No idea. But probably

2. If it seems like it's working fine, I wouldn't worry about it until/unless an issue appears
