Hello all, I factory unlocked an ATT Galaxy S9 and then successfully flashed to Unlocked firmware via ODIN. Recently acquired an S9+ and want to give the S9 to my mother. How do I go about restoring everything back to default, and back to default ATT firmware?
Thank you in advance! I'm hoping to do it this week so she can have the phone! Blessings! :good:
Same way you flashed the U1 firmware, Odin 3.13.1 and the stock ATT firmware
Did you ever figure this out? I used Odin to flash the U1 firmware so I could try the beta. Overall it worked pretty good, with the only exception being signal strength. I know I can flash U1 firmware, but I'm trying to get back to the original U firmware.

Hi,
I followed this post to update my Note 8 to Oreo. I didn't read it carefully enough to realize that its firmware is N950U, which brings all the good bloatwares and carrier firmware. Now, I would like to revert back to Nougat 7.1.1 with stock/pure Samsung firmware. Before messing my phone up, the baseband version was N950USQU1AQI5. My phone's carrier is XAA (the phone is factory unlocked). I have looked everywhere to find this firmware but the only one I find that is XAA is N950U1UEU1AQI5, which is for the U1 models not U (mine is N950UZKAXAA).
Can some one PLEASE help me get rid of Oreo and this carrier firmware and restore my phone to the original firmware it shipped with?
i think Oreo might have the bootloader v3, so you probably cant go back to what it shipped with (bootloader v1 or v2). You might be able to flash BRA5 and whatever was right before it (which is 7.1.1) because that did have the v3 bootloader.
I think U1 is for the unlocked model, so I'm pretty sure thats what you'd want to be flashing.
1. Download SamFirm
2. put in "SM-N950U1" for Model and "XAA" for region
By the way, I think this is the wrong forum for the Note8
I'm sorry, i don't know what you are talking about.
Any chance you could help?
Hi,
I have a Samsung Note 8 Tablet, GT-N5110 that's stuck on the Samsung logo.
Any chance you could help me revive it?

Hello All,
Recently I was able to flash my US AT&T branded G960U to the Samsung unbranded U1 version. After I did that, I flashed my phone using an official TMobile Rom, Oreo I believe. At the time, the boot loader was not locked.
Today I tried flashing back to the Samsung U1 firmware and it keeps failing as I believe that my boot loader is now locked which may have been caused by the TMO ROM.
When I did the flashing, I used the Modded Odin v3.13.1 Raymonf version. I tried the exact same steps tonight again and no luck. I tried on two different computers, have the drivers, files, etc.
Any known work arounds or fixes? I want to go back to the U1 version so I can upgrade to the Oreo 8.1 due to alot of bugs in Oreo 8.0
Thank you

Have the same problem here
The reason you cannot go back to u1 firmware is b/c the att and t mobile firmwares are newer and updated the bootloader to v2 hence you can't go back to the u1 firmware which has a v1 bootloader.

Yeah I think I'm stuck too, however I don't mind as all the t mobile bloatware was able to be uninstalled and it's very responsive. Seems as if arc6 (tmb, 960u) is very fast and doesn't have any of the hiccups I noticed on the Canadian firmware (Telus arc1 seemed better but not as new as arc6 and also a one month older security bulletin).
I'm ok with being stuck however, we just need a U1 firmware with the v2 BL if I'm not mistaken.
How do you tell what version bootloader you are running?

I don't know, I just assume the may security update has it.
Forth character from right side is the bootloader version.
I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?
No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model
I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?
I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

That'll be why I still thought that then, coming straight from the S7 > S9
Had many members flashing the wrong firmwares thinking they could do that and bricking their S7s / wondering why ODIN failed

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint
As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?
HAPPY FLASHING!

Hi, I got one unlocked G960U1(G960U1UES3ARI1) and downloaded new fireware(G960U1UES3ARI1-SPR) from sammobile, but after flashed SPR ROM successfully, the info on the phone still shows XAA, anything I missed here? Thanks!

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.
hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

well, I tried to load the Sprint image from the VZW, no dice. It said it passed, but upon reboot loaded up the old Big Red (even with the Sprint SIM in it).
Anyone have any ideas? This is driving me insane....
Hey all,
I am trying to flash the Tmo firmware onto my unlocked Ultra to get things like the video call option in the dialer, and for the life of me I am getting lost.
I used both Frija and SamFirm to downlad what it said was the correct firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) putting TMB in the CSC. I flashed that firmware using Odin,
Here is what I did:
Downloaded the firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) in Frija putting TMB in the CSC box
Unzipped all the files
Flashed them all to the phone in Odin, using HOME_CSC_OMC_OYM_G988U1OYM1ATCH_CL18186338_QB29814488_REV00_user_low_ship_MULTI_CERT.tar.md5 so as not to wipe my data
There is no error, and it finishes successfully, the phone reboots, and there is no change whatsoever.
Am I missing a step here guys?
Thanks so much.
**EDIT**
I finally figured it out.
I needed to flash the TMB U firmware, not the U1 firmware.
Curious do you notice better signal strength on TMO U firmware vs unlocked U1?
I have an unlocked, not rooted and factory OS Verizon(SM-G988U) with Android 10. I recently switched to T-mobile and was thinking to flash the firmware from Verizon to Tmobile to better use their wifi calling and other features.
Where can I get the latest files to flash the firmware? Also, to switch from Verizon to Tmobile, do I have to flash Verizon-->Unlocked(U1)-->Tmobile or can I do Verizon directly to Tmobile firmware? I read few threads but I was confused on what exactly I need to do.
I downloaded Odin v3.14.1 and latest Samsung drivers. Beside the firmware files and placing appropriate folders in BL, AP, CP and CSC, anything else I need to do?
Sorry for noob question but this is my first flash and was looking for exact steps.
Thank You
You need to go Verizon-unlocked-Tmobile. You'll want the patched Odin too. I use Frija to get my firmwares https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910584/ but you can use sammobile as well.
Thank You. Is Frija 1.4.3 the latest version?
Also, the Odin I downloaded, the executable says "Odin3 v3.14.1_3B_PatcheD" which I suppose is latest and patched, right?
In the Frija, CSC, I got the Tmobile firmware as TMB. What is the code for the unlocked firmware so I can download it?
Also, do I need to root to flash the firmware from Verizon-->unlocked-->Tmob?
Noyou do not need root
In the Frija, CSC, I got the Tmobile firmware as TMB. What is the code for the unlocked firmware so I can download it?
Never mind found out.
SM-G988U1 , CSC- XAA for Unlocked
and
SM-G988U, CSC- TMOB for Tmobile.
Were you ever able to get WiFi calling to work?
