Hello I've been trying to reset my phone as whenever I booted it would just go to a blue screen and restart. I've erased the OS on it, unlocked the bootloader, installed TWRP but there are no ROMs online for this model's carrier.
Would appreciate it if someone could post an updated link on how to fix this please?
Many thanks.

I recently purchased the G920t factory unlocked version on Amazon. I rooted it and installed a custom ROM. I was hoping that someone could help me out with finding the stock firmware for the factory unlocked variant. I believe it is slightly different from the standard T-mobile firmware, as it didn't include any t-mobile apps, etc. The reason I was asking is I've been having call quality issues and wanted to flash back to stock to see if it would be resolved, but didn't want to flash to the standard t-mobile stock as I believe it is slightly different. I know I should have made a back up before flashing a custom ROM but I failed to do so and am now trying to fix the issue afterwards.
Thank you so much for any help you can offer.
What firmware was on it originally? What baseband?
My USA factory unlocked 920T shows a baseband of G920TUEU3COK1 after the latest OTA update was installed. XDA rules don't allow me to post links to SamMobile firmwares. You can search their site for "920T", but don't used the "SM-G920T1" search result. The proper firmware has "Cellular South" as the Country/Carrier.
Thank you so, so much. So that'll allow me to roll it back to the way it was right out of the box?

yes, but I don't think it'll reset the knox counter to zero.
Hey, so I'm really new to Android (this Note 5 is my first Android phone) and I don't know much about firmware flashing, so I thought I would inquire here... I have the SM-N920I model of the phone, but it was a Spark (New Zealand carrier) phone so it's not factory unlocked but it has been unlocked as I can use my Vodafone SIM. Since it has the Spark firmware, there is the Spark boot animation, and I was wondering if I could flash the factory unlocked firmware onto the device to get rid of this and a couple other things that bug me a little with the carrier firmware.
Thanks for any help guys!
T-mobile Note 8 , installed Unlocked ROM but T-mobile start up is still there on every boot. Can anyone help me get rid of it. There is no stable guide for switching firmwares and the ones that do exist are not working for me because Odin will simply give me error while flashing some of the ones posted on here. I tried one XAA Unlocked ROM which installed fine but T-mobile boot up is still there. any help will be appreciated Please....

You'll need root to change it.

You need the ROM from U1 model, not U.
Hi All,
I was hoping someone could point me in the right direction.
I have an unlocked Note 8 (Model SM-N950U1) that I flashed a version of Verizon 8.0.0 to (N950USQU3CRB1). I've looked around the forums quite a bit and can't seem to find any way to go back to my original unlocked software. Ideally, I'd like to be on the most current version, but I'm not sure how to get there.
Any ideas?
Thanks in advance for your help!
There's two threads called carrier switching that deal with this in great detailed guides.
The abbreviated version is, download the N950U1 fimrware with SamFirm.
Flash it with patched ODIN 3.13.1_3B
Just advice, next time before you flash firmware on your phone, make sure you understand the procedure for.goijg back to stock as well.
Hi i am new here and need help with updating my Samsung note 9 i still have a baseband N960USQS1ARI5 but will like to update to the latest firmware. i'm using an unlocked AT&T phone. can anyone guide me? I'm not sure if updating the firmware will lock the phone and the process to update, do I just update the firmware in stages as the updates were released till i get to the latest update or can i update straight up to the latest? I am thinking of using Odin, is that a safe way to do this? any help will be appreciated. Lastly, can I change from the AT&T firmware to lets say a none carrier based firmware so as to stop seeing the AT&T logo on boot up? Maybe switch to a firmware that supports global or international? Does anyone have links to an unlocked firmware update i can use, as well? Please help!
I must state that the phone never updates automatically as it always says the software is up to date.

to your last point, at&t phones are notoriously bad at updating
factory unlocked phones will remain forever unlocked and phones unlocked that are bespoke to a specific carrier will also remain unlocked even with Odin flashes providing that the method employed to unlock it was legitimate. Some unlock methods employ root and only trick the phone into thinking its unlocked. Well, once you remove root, and thusly the trick, the unlock is gone. I have ran across rare examples where the person swore up and down that they unlocked their phone with a legit unlock code and that it relocked to a carrier once the sim was inserted and initial programming completed, but i dunno. Sounds weird to me, but every person who said this also said that the phone locked to a carrier other than the one it came from originally. Take that for what its worth, but i still mostly stand by the first couple lines of this section of my diatribe
If you want the at&t crap gone, get the N960U1 firmware and flash it in Odin. You will need the modified version of Odin to flash it so it can ignore the 255 errors the phone throws up from flashing firmware for a carrier (or, in this case, no carrier) on to a phone that it wasnt originally designated (not designed) for
go to sammobile.com/firmwares, get the info for the firmware you want to d/l, get the Frija tool or Samfirm and download the firmware thru one of those as theyre literally 5x faster and flash it
