Question SM-F721U1 with sm-f721u firmware - Samsung Galaxy Z Flip 4

Hi all,
Anyone tried to burn a SM-F721U1 device with sm-f721u firmware?
I remember doing it on a note10. Question is if it's still possible?

seems to flash just fine. I have only found tmo and u1 with july patch... are there others?

I tried. Mobile network get disabled. Grey out in status bar. I am using US Mobile services. I have to do a fresh flash A12 VZW build to get back working handset.

I was wondering this as well. I purchased my first unlocked phone and now I wait for the 13 update, while the T-Mobile version is already out. I am on T-Mobile, so I'm guessing it will work just fine. Will my phone still be "unlocked" if I flash the SM-F721U firmware?

unlocked want to flash firmware

Was on ATT, unlocked, now on T-Mobile. Phone is 3 yrs old, sketchy; shuts off randomly, has issues. Want to flash firmware, but Sammobile doesn't have 915a. Since it's unlocked and on t-mobile network, can I flash with t-mobile firmware? Can you put any carrier's rom on an unlocked phone? Sammobile has "usa" firmware with no carrier designation.

Did you find a solution? I flashed the firmware uploaded by makki666 found in another thread on updates for Note Edge from at&t. Right now am using 6.0.1 but may revert to basic 5.1 1 to get temporary root & get rid of bloatware (have not figured out what is worse, outdated OS or bloatware). If you found a better solution, please posr

Sprint S8 Active flash to T-Mobile?

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.

I AM NOT THE CREATOR NOR DO I TAKE CREDIT FOR THIS
No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?
Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?
I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint
Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.
So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

After flashing Sprint variant of the device to T-Mobile firmware, do all features work: WiFi Calling, Band 12, VoLTE and Band 71?

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".

AT&T Note 8 on T-Mobile

Upgraded to Note 9, want to pass my Note 8 on to a T-Mobile user. I want a complete T-Mobile experience, so all T-Mobile bloat and settings are needed (VoLTE, Hotspot, etc...) . Note 8 currently has latest CRID OTA from ATT. Looking for help in determining the correct way to proceed. I am having AT&T carrier unlock the device, so I would make this change after confirmed unlock. Also, once this is finished, will the device receive T-Mobile OTA updates?
I have read through https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884 but am confused. I see lots of mention of combination files, CSC changing, etc... that seem overkill for what i'm looking for.
Are these the steps I need to take?
1) Download latest Odin compatible TMB Firmware (which is what version?)
2) Download Odin on PC
3) Factory reset Note 8
4) Flash TMB firmware
5) Insert TMB SIM card
6) Success?
Yes just download this file

Flash everything with Odin and you will have a full 100% T-Mobile Note8 with all carrier features working

I saw here that simply flashing a different carrier firmware will not actually change carriers?? Is that correct?

Someone in that thread said I would need to flash an unlocked U1 firmware and then the TMB firmware?
I am about to do this as well, switching from AT&T to T Mobile using my AT&T branded Note 8. I just wanted to confirm that it's as simple as downloading the latest Android Pie firmware for T Mobile and flash it to the AT&T branded phone? Any precaution like some other thread mentioned to flash the U1 (unlocked) firmware first then flash the T Mobile firmware?
Also, eventually, I will be giving this Note 8 to someone in China. At that point, is it better to flash the unlocked version of firmware or just leave the T Mobile firmware on it?
Thanks so much for your help.
Note: the phone is already unlocked.
I just wanted to let everyone know that I went and got T Mobile. After the new SIM card was inserted in my AT&T Note 8, after a reboot, it did something, a screen with a SIM car graphics and some moving dot. Then it rebooted itself again, and then T Mobile splash screen showed up. It even added the bloatware from T Mobile. So, Android 9 for Note 8 probably has both ROMs? I also checked the firmware version. It shows the latest T Mobile ROM.
I didn't have to do anything other than just inserting the new SIM card from T Mobile.
This is very interesting to me, and the store guy couldn't believe his eyes either.

And i was wondering why my phone still showing at&t bloatware even after installing the Verizon firmware. ? Now i understand Cuz I'm using at&t sim. Good to know?
Another update!
I just got updated by T-Mobile to the latest firmware after converting over as previously stated. I have to say that the update page on the phone for the T-Mobile firmware is MUCH nicer and informative than the ATT version. It tells you how much time left, the version numbers, and even a "what's new" section...
After this update, my phone is actually better at battery usage.

Flash S10+ to get latest security patches

Hi there, new member with a first question.
I bought an S10+ (SM-G975U) online, unlocked, to be used mainly with AT&T when in US, and different carriers when traveling. IMEA check shows the phone was originally on Verizon carrier, but works fine with AT&T sim card. However, it's not receiving OTA software updates, and the security patches are way behind. When I try to force software updates, says it's already up to date. Seems like on unlocked phones, or switched carriers the updates don't happen. I tried booting the phone with a working Verizon sim card, still no updates. Online searches say that flashing the firmware is my best (or only) option. I downloaded Odin, but I still have a lot to learn and don't want to brick my phone. I'm not sure which firmware version to get. AT&T vs Verizon? U or U1 since it's unlocked? Do I flash all 5 files or just some of them?
Thanks.

A small Update Issue on the Note 10+ 5G Verizon Help?

Hello everyone, this is my first post here.
I have a slight problem. I have an unlocked verizon Note 10+ 5G SM-976V and I changed CSC to GCF a while back because the verizon CSC had bloatware.
Now i have GCF/GCF/VZW. Im stuck on March 1 2020 security patch. The phone works great and everything is working well. I want to upgrade to android 11. That is somewhat not possible because when i try to upgrade from my phone it says, 'Your current software version isnt supported. Visit a service center.'
What firmware is for me? How can i get an firmware that can fix my usual updates? Or if i have upgrade firmware on odin, what version should i be choosing?
I do not live in the US anymore, phone was unlocked on verizon. All sims seem to be working on it. Attaching the files necessary for your study. Please help?

Have a look here for official ota updates from Verizon: https://www.verizon.com/support/samsung-galaxy-note-10-plus-5g-update/
If it does not work and you have an unlocked bootloader, you can flash latest stock firmware with Odin on pc.
