Hello,

Hopefully I can get answers in this thread.

My phone is G975F/DS with CSC-TPA (see attached). I am in the US, main sim is TMO and second sim is from Israel. I currently have VoLTE as well as WiFi calling in both my TMO and ILO sims.

Can I safely flash BTU or DBT (or any other firmware) without losing these two features? Is one better than the other (BTU vs DBT or another OXM firmware)? My objective is to get updates as soon as they come out and some countries receive them before others. With TPA I am still with Sep. security update and TPA doesn't seem to receive updates early enough.

And a stupid question: do I flash in Odin with sim in or out of the device? I know it affects the flash in different ways and I still don't understand that part, why it's important for the sim to be in or out.

Thank you.

Just flash it as you would flash a normal stock ROM.

No special method required.

ATT Userdata?

If I purchased this Latin American (snapdragon) Galaxy S10+ SM-G975F Dual SIM https://www.bhphotovideo.com/c/product/1465801-REG/samsung_sm_g975fdsgrn_galaxy_s10_g975f_dual.html is it possible to Flash the ATT UserData file for an S10+ ? Which firmware would I actually need to use this phone in the USA on ATT & T-Mo? From what I can tell, the Multi-CSC info is specifically for non-USA carriers.

I never had one before but I would like a Dual SIM phone to use mainly with ATT with a T-Mo SIM in the 2nd slot. With ATT, I'm in a more rural area so having wifi calling is a must plus VoLTE is really needed. I have an Unlocked Note 10+ that I had to flash the ATT Userdata file so I can actually use the phone in my home. Otherwise service is really poor without the ATT bloatware (and also had to use an ATT SIM that had been previously used on an ATT carrier-branded phone). THX!
[Samsung Galaxy S10+ Guides, News, & Discussion] sbi1:
This phone is not Snapdragon, it is Exynos. All outside-USA S10+ are Exynos.

I am currently using this model on TMO, I have VoLTE and Wifi Calling.

Been a while since I have flashed with Odin and just after some advice please fellow flashers. I am on Vodafone australia with a g975f and sick of the slow updates so was going to flash unbranded Australian firmware. Don't want to lose such things as vo lte from Vodafone so need to keep the Vodafone csc. How can I do this without wiping the phone and considering Vodafone au is about 2 months behind in firmware
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Flashing from carrier to unbranded will always require a wipe if you want it done properly and with the ability to get OTAs once on the unbranded channel.

You should still get VoLTE being on XSA (Australia unbranded).
[Samsung Galaxy S10+ Guides, News, & Discussion] sswagonman:
Awesome thanks heaps. The vo lte was my main question as I just wanted clarification on the rest. Cheers appreciate it heaps

Hey, thanks for the guide.

I flashed the AUT OXM firmware from SamFirm onto my TPA/TPA/TPA/TPA phone but it still says TPA/TPA/TPA/TPA. I'm in Canada with a Canadian SIM though, and this should be an international unlocked phone. Is there a reason the CSC does not change? Or is it because TPA is the closest G975F CSC?

Thanks for the help.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
It won't change to AUT or any other G975F CSC unless you insert a SIM card from a region where the G975F is officially sold, such as Europe, Asia or the Middle East.

It doesn't officially recognise Canadian SIM cards so it can't switch to a Canadian CSC.

Assuming the DBT Release of Android Q will work fine on BTU.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
It most definitely will.

If the same build is released for BTU as well, you'll even get OTAs.

Hi guys. Just want to confirm if dirty flashing BSKO over ASK1 would be fine? Or a clean wipe is recommended? Thanks!
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Dirty flash would work, but since it's a major update, a clean flash would always be recommended.
[Samsung Galaxy S10+ Guides, News, & Discussion] tiho5:
I see that NiceLock and quick settings button grid aren't available yet in Q.

Therefore I'm skipping it for now. But will it be OK when a following version of of Android Q (with the above-mentioned working already) is out to update straight to it from ask1 without loosing data? Or I have to flash sequentially all the updates.

I apologize, I know the OP has information on this, but as this is an android update, not just Samsung FW update, I decided to ask.
[Samsung Galaxy S10+ Guides, News, & Discussion] DubelBoom:
Will flashing with HOME_CSC restore all "removed" (pm uninstall -k --user 0) packages?

[Samsung Galaxy S10+ Guides, News, & Discussion] MitoTakatori:
Thank youy friend.
[Samsung Galaxy S10+ Guides, News, & Discussion] tiho5:
Please, answer:

The bootloader version is only the number/digit after XXU or XXS, am I correct?

I want to make sure if downgrade from XXS1 to XXU1 is possible.

So is only just the digit what's the important one here as to bootloader being higher or lower version?

Really helpful and well built OP. Thank you!
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Yes, the software 'revision' as we call it, it the digit immediately after the XXU or XXS prefix.

A downgrade between XXU1 and XXS1 builds is definitely possible.

There is another FAQ in the OP explaining the difference between XXU and XXS.

Check that out :)

Trying to flash for the first time

Hi, i'm really new to flashing, i have learned the basics but i'm still really not sure about one thing. My s10+'s csc code is XID, i want to flash DBT firmware onto it, will the non home csc method work?, thanks.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
XID is on an entirely different CSC base (OLE), whereas DBT is part of OXM.

You can flash it, but you will have to use CSC_OXM when switching from XID.
[Samsung Galaxy S10+ Guides, News, & Discussion] z2fra:
Okay, but can i go back to my home firmware if the update is available for OLE?, just use the same method?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Yes you can. You will have to reset the device to go back to OLE, but the procedure is the exact same.

I cannot get Odin to start for the life of me. It shows the com and that it's connected correctly but I never get the green thing on top to say ready.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
What happens when you press start to begin the flash?
[Samsung Galaxy S10+ Guides, News, & Discussion] carnivalrejectq:
Nevermind. At first I thought nothing was happening. Turns out my computer is just that slow and I needed to wait. After a while it began to do its thing. I just could've sworn it used to pop up and say ready in green first and foremost lol
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Odin has to check the MD5 hashes of each file as they're added.

Doesn't take more than a few seconds for BL, CP and CSC since they're all quite small, but since the AP file is usually between 2 to 6 GB depending on the device, Odin struggles a little bit when verifying that file. Some people usually just close Odin cause it shows 'Not Responding' in the window title, but it's normal for it to take long.

Glad to hear you figured it out.

I tried 6 times, from Frija app, SamFirm app and SamMobile, with different downloads! I used different Odin versions!

Where can I find the true ZTO ROM for Android 10?

Is possible do downgrade from Android 10 ARO to Android 9 ZTO? After use Android 9 ZTO, I may do update to Android 10 over OTA.

I have a other S10+ with Android 10 (Android 9 ZTO + OTA updated to Android 10 ZTO). Is possible extratct ROM for use on new phone?

Anybody help me ?
[Samsung Galaxy S10+ Guides, News, & Discussion] jrc91:
Was there ever a fix for this as I've got the same issue?

Does the region lock need to be removed by SamKey or can a factory reset still change the CSC as I've been unable to get it to change so far.

Thanks!
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Haven't found a workaround for it.

You'll have to use SamKey or alternative methods to get rid of the region lock.

Wow, fake firmwares?

This isn't a question or anything, I was just amazed today - I bought a Exynos 975FD on amazon and got a phone running Android 9 and showed its firmware version as G975FXXS3ASH1, showed two IMEIs, etc. However the bootloader was already unlocked which made me suspicious because no way would Samsung ship a phone that way.

I tried to update it to to android 10 G975FXXU3BTA8 official firmware for 975FD, but the bootloader rejected it with "SECURE CHECK FAILED." The download mode screen was in Korean and in the upper corner said "SM-G975N" and would only accept the G975N firmware. It upgraded to Korean 975N firmware with no problem.

Do sketchy sellers have some way of overriding the bootloader check and getting it to run the 975FD firmware? Or are they just loading a customized firmware tweaked to pretend to be the international model? I'm really amazed at what bull**** this is. Fortunately Amazon will make the seller refund it.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
It's basically a G975N with a modified ROM to make it look like a G975F. That's why the bootloader was unlocked.

Common practice by sketchy sellers and scammers to try and sell off the Korean variants which are worth less than the International variants.

Return it ASAP.
[Samsung Galaxy S10+ Guides, News, & Discussion] epv:
Already done. Thanks for confirming I'm not crazy :) I ordered one from the ebay seller that people on here were recommending, instead.
[Samsung Galaxy S10+ Guides, News, & Discussion] Veestaai:
I have read the FAQ section. Is there any method to go back to a previous bootloader version firmware by any hook or crook?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Not that I know of.

I believe even a modified Odin won't work because the phone itself rejects the file with the 'BL REV' error in download mode.

It won't even begin the flashing process because of a version mismatch, so when you upgrade to a certain BL rev, just consider yourself stuck there.
[Samsung Galaxy S10+ Guides, News, & Discussion] MBurton9049:
Bought an S10+ from eBay which was originally locked to AT&T. Where I bought it from unlocked it and now I'm on a Telus (Canada) sim. Because of all this I cant get any OTA updates. Im sitting on Android 9, and would like to move to 10 as well as get the updated security patches that I've been missing. I have read a little about Odin as well as Samfirm. I backed up my device using Smart Switch, so hopefully I will be able to put all my data back after this is done. I would appreciate advice or direction re Odin vs Samfirm and if I should stick with the ATT firmware or if I can just grab Telus since thats my SIM. Phone is G975U showing CSC of ATT. TIA from a rookie.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Telus is a Canadian carrier, and Canada uses the SM-G975W variant of the S10+.

You could grab the G975W XAC firmware which is for unbranded + unlocked devices.

Flash it using a patched version of Odin which you can get from here:

https://androidfilehost.com/?fid=6006931924117912211

The firmware can be downloaded using SamFirm (It says deprecated, but ignore that because it still works).

https://xdaforums.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647/

Use SM-G975W as the model number and XAC as the region / CSC code.

The latest firmware should automatically be pulled from the server which is G975WVLS3CTA3, based on Android 10.

Hey guys, i am new on the samsung hardware world and need some guidance.

I live in Brazil and have a SM-G975F, CSC: G975FOWO4BTB1, AP: G975FXXU4BTC1, CP: G975FXXU4BTAA.

I wanna install the new OneUI released on several european countries, like Germany. The PDA: G975FXXU4CTC9 and CSC: G975FOXM4CTC5 of the new build are those.

Can i install it on my device without any problem?
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
You can install it but you will lose features like Samsung Pay, VoLTE and WiFi calling as you will change from Brazilian OWO CSC to International OXM CSC base.
[Samsung Galaxy S10+ Guides, News, & Discussion] VertigoOneX:
If I flash the new S10+ firmware for UI 2.1, I have the latest firmware just before that one, via SD card method from stock recovery, will it reset my data or just update without formatting memory? My device is unlocked and my phone had exactly the same firmware build releases as in the other thread.

I read in the mentioned thread that you can rename the bin file to zip and install from recovery option but I'm not sure what will happen to my data.
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
As far as I know, there is no bin file for the 2.0 to 2.1 update.

You'll have to download the entire stock firmware and flash it with the no-wipe option that will allow you to keep all your data.

I bought my S10+ from Amazon a while ago but I still haven't received the update from 2.0 to 2.1 I believe the phone came from Australia but I'm in the US on T-Mobile is there anyway for me to change the region from Australia to the US because I'm getting prompts for things I can't use here.

My baseband is TAA
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
You won't be able to change region as the S10+ you bought is meant for the international market and not for the US.

You could manually flash the 2.1 update using the instructions in the main post of this thread.

i was running a rooted S10+ but wanted to go back to stock so i flashed the latest G975FXXU8CTG4 in ODIN and this was passed succesfull

after reboot it go to stock recovery and starting erase but this seems to fail and go's to a recovery loop.

can someone please help me to get to stock?

[Samsung Galaxy S10+ Guides, News, & Discussion] mpjjansen:
I tried both but it isn't working
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
Don't try HOME_CSC.

Flash AP, BL, CP and CSC_OXM.

After flashing, hold all the buttons to force the device to power off. Then hold power + Bixby + vol up to get into recovery mode. Wipe data / factory reset and reboot the device.
[Samsung Galaxy S10+ Guides, News, & Discussion] mpjjansen:
i tried the suggested solution

in ODIN unticked auto reboot and flashed the software (passed)

booted in recovery and wiped data and rebooted

I see a quick screen installing update and then erasing and within 2 seconds a black screen and nothing happens.

The only thing i can do is press the hold power + Bixby + vol up and recovery is started again

really frustrating
[Samsung Galaxy S10+ Guides, News, & Discussion] MeltdownSpectre:
You can try repairing the device with emergency recovery using the Smart Switch app on PC.

If it still doesn't boot after, seems like there's a problem with your flash storage chip.

But the strange thing is that if i flash TWRP and then can flash a custom rom with no problems.

So i don't understand why reverting back to stock isnt't working.
[Samsung Galaxy S10+ Guides, News, & Discussion] mpjjansen:
I give up i really dont understand what is happening and why i cannot go to a stock rom.

the steps i dit

1. download the latest ctg4 rom from sammobile

2. fashed the rom in ODIN (passed)

3. after reboot the message erase appears for a few seconds and than a black screen.

4. I can boot in stock recovery and wipe data/factory reset but after reboot en reboots in recovery

5. tried to manually reboot directy n recovery and wipe data but same errror.

I look like there is a problem with erasing in the stock recovery but i don't understand why??

--------

When is flash twrp_beyond2lte_3.3.1-3_corsicanu in odin and reboot is can acces TWRP and i can install a custom rom with no problems.

Is there someone with the solution :)
