My Baseband version is G96USQS7DTE1 with a Carrier configuration 2.3900001 It is on T-mobile but I want to move it to Altice Mobile. I was told the easiest way is to flash it to the Sprint Firmware first. How do I do this?
you probably just have the wrong csc. if the phones paid off why doesn't the carrier handle it?

Why not just try installing a sim card from Atlantic Mobile. When I purchased my S9 plus it was for T-mobile.. After installing the Sprint Sim and having it activated, it turned into a Sprint phone.. Even the T-Mobile, splash screen was replaced with the Sprint Splash Screen.. No need to root or even flash Sprint firmware.

Hi, could I flash the t-mobile firmware file or rom to the verizon lg g5? I switched to t-mobile, and am able to use the verizon phone, but lte drops to 3g for calls and lots of the time data shows up as hspa when I check the icon. If it can be done, please explain how. Thanks in advance.
No you can't flash the T Mobile firmware.
other firmwares beeing flashed on different lg g5's
So, there is no way to flash different firmwares on the verizon model, just other ones. Is this because the bootloader is locked? How can people flash a different region firmware on some of the models?
I to am curious on this, i have called LG and was told that the only difference between the T-Mobile and the Verizon LG G5, was software based, and that their was no hardware differences at all.
If that is true, why would we not be able to flash the T-Mobile rom onto our verizon phone?
DO NOT ATTEMPT THIS OR YOU WILL BRICK YOUR PHONE BEYOND ANY REPAIR. It has been said MANY times before, google it first

The hardware is essentially different... Has nothing to do with locked bootloader, u could still use LGUP to flash regardless but it would likely brick your phone. Drops to 3g because of the bands used, there may be a workaround but it's unlikely.
I used to have an unbranded S6 Edge after selling it I missed it so much so I got a secondhand one yesterday. After factory reset, the first thing it did was install all kinds of Vodafone apps. As a TMobile user with a Tmobile Simcard I guess the Phone has been unlocked by the former owner. Or can Vodafone do this and still have all the apps installed?
I would like to flash the unbranded Dutch stock rom on in but in case the former owner did sim unlock it would I loose the sim unlock then? Is there a way to tell the Phone has been software unlocked or through the carrier?
Rght now it has Baseband G925FXXU4DPIT and MMB29K.G925FXXU4DPJG Buildnummer
And I would like to flash PDA:G925FXXU4DPJH CSC:G925FPHN4DPJE

Flashing a stock ROM should not lose the sim lock. Network lock isn't done by software flashing. It's done with the imei. You should be able to flash any stock ROM including branded firmware and you won't lose the unlocked network
Hi All, I have unlock ATT version, then switch to T mobile service (flash T mobile firmware). Now I switch to Sprint firmware. HOwever My ATT ver didn't have the band 25 and 26. Only have band 41. Sprint needs all 3 for better connection. Is there away to unlock 25 and 26 band?

The G965U and G965U1 are identical hardware wise and all support the same bands. What differentiates the G965U from the G965U1 is the that the G965U1 has the unlocked firmware (non carrier branded if that term makes more sense).
The only thing that differentiates one G965U from another G965U is the firmware. The firmware determines what bands are available as well as custom carrier settings/apps/configurations that is installed. For example if you properly flash the firmware for the Sprint G965U onto the AT&T G965U then it will have all the bands (and sprint customization/bloat) that the Sprint G965U version has.
To give you an example I have the sprint version, flashed it to the unlocked firmware, flashed to AT&T firmware and then finally to T-mobile. I didn't flash it in that order, that is just the different kinds of firmwares I have had on that phone.
Across the different firmware versions all necessary and needed bands were active and working just fine.

Yes, i put in Sprint Sim on the phone then the phone auto removed the Tmobile apps and installed bunch of Sprint apps. I checked the specs for ATT ver and only see band 41 avail online. After Sprint firmware installed, I check again *#0011# and only see band 41. I was too assumed everything should be identical both S9 plus U or U1 but there must me something got block by ATT and carrier firmwares still can't unlock it.

Did you flash the sprint firmware onto the at&t phone you have or did you just insert the sim card and let the phone apply the settings for the sim card?
If you did the latter (specifically just changing the sim card) this doesn't give you any of the carrier specific tweaks/customizations that can be found on the carrier firmware. For thse tweaks/customizations you need to flash the firmware for the carrier branded phone. So your better connection desire will most likely be a sprint firmware specific thing and not found on the at&t firmware.
Also looking up what the at&t branded phone supports and the sprint branded phone supports won't help much. It will only tell you what the two phones are configured to do for the carrier the phone is branded for. Those specs It do not tell you what the hardware can do (or that the hardware is the same whether it be the unlocked version from Samsung, the sprint branded one you buy from sprint or the at&t branded one purchased through at&t).

This makes sense. I'll will try to flash Sprint firmware on top right now. The reason I said tweaks/customization applied because the whole UI "Settings" of the change completely changed from Tmobile Pie to Sprint Pie (more buttons, header rename...) so I assume tweaks/customizations already applied when Sprint Simcard did its own things
Also I thought the base S9 Pie for U ver all the same. Only when you put the Carrier simcard in then they download their all carrier settings (Not in this case?

Carrier settings (APN, MMS/SMS settings, PRL, Roaming lists and related) are not quite the same when it comes to bands being enabled/disabled or carrier tweaks/customizations. Also I don't know if the base for the s9+ contains all the full carrier customizations/tweaks or not when it comes to android pie. If I had to guess I would say it probably comes with a somewhat generic one size fits all configuration... Perhaps along the lines of what the U1 firmware has.
Though I would presume that the base does not have all the carrier customizations/tweaks because the carriers release android pie at different times.
As an example (for illustrative purposes to explain my presumption) AT&T releases the new update before T-mobile does. T-mobile releases the update before Verizon does. Because Verizon would have been the last to release the update both AT&T and T-Mobile would not have any of the additions Verizon would have made.
When flashing the sprint firmware onto the AT&T phone you have you may need to flash the U1 firmware first, do a factory data reset and then flash the G965U firmware for sprint. Someone else might have some insight if this is still applicable for Android Pie, but when I flashed from sprint to t-mobile using the Oreo firmware that is the process I had to go through.

I would debate on the example (for illustrative purposes to explain my presumption) you had above, I don't think carriers are related. I would think Google/Samsung (Google may give the base to Samsung first then Samsung distribute to each carrier) give each carrier the base then each carrier goes customize their own settings with their own times to release to us.
Yes the correct way to flash to U1 then flash back to be clean (I guess And I did that when switch from ATT to Tmobile) But i have to much to setup again, so may just dirty flash Sprint now
PS: Still can't find the Sprint Pie in Sammobile website. Only Verizon and Tmobile and Generic ver

I am not sure if this would work or not and I haven't done this for a while. I might have the wrong service code or the menu option may have changed with android pie. So if I do someone feel free to correct it.
Note - if you see a message like RAT access/menu isnt allowed (or something like this) power off the phone, take the sim card out and power the phone on without the sim card in it. The process should work then.
*Open the phone app and enter ##DATA# (##3282#)
*Choose edit and if prompted enter a total of siix zeros as the MSL
*Select LTE to edit the active bands
From there you can enable or disable bands. If the band isn't listed you simply cant just add it. I would suggest flashing the carrier firmware as this would have it enabled.
Also I do believe that there are carrier customization/tweaks that may only be on the firmware from the carrier. Swapping the sim may change a few apps, change a few menu items and apply settings from the sim card onto the phone. It also may apply some (or perhaps most) carrier settings. I have not seen anything that gives me cause to believe that it applies all the carrier customization/tweaks.
If that were the case why did my g96u1 (or sprint g965u) firmware not show video calling or get provisioned for it, but flashing the tmobile firmware allowed for the feature to be enabled and provisioned. Also on the tmobile firmware I have had better signal retention and strength (not the signal bars, actual signal strength measurements on the phone) then with the unlocked firmware (or the original firmware that was on the phone with the tmobile sim).
If swapping the sim installs the tmobile firmware then that should have been all it took and I could continue to use the unlocked firmware, but this was not the case. The only features that were enabled were (outside of menu changes and app additions) VoLTE and WiFi calling. Now if this alone indicates carrier firmware specific features/tweaks/customizations can only reside on carrier firmware, then how could one declare it wouldn't also effect what bands are enabled/disabled. Like I said I haven't seen anything that says otherwise, but from what I have seen first hand there are somethings that are apparently only on the carrier's firmware that is not available on the others.
Hi i bought myself an unlocked att v60 thinking that i will get updates but it seems like without the carrier sim i wont be able to get any updates and no im thinking to flash an international firmware on my att firmware is it possible my model is lm-v600AM and i want to flash firmware of lm-v600tm my firmware verison is q. Anyone please is there anyway to get updates and also Im from dubai so there is no way i will get hands on att sim .
Hello, looking for some help to see if anyone can help me find the firmware of my A526U specifically for AT&T? I have moved my phone over from TMobile where I purchased it from, and am looking to re-flash it to AT&T. Was working fine for a few months, now I'm no longer able to make or receive calls.
After inserting the new AT&T SIM card, the TMobile splash screen still shows up. The Service Provider software version reflects TMobile still as well and I'm concerned that for whatever reason the phone did not fully update after inserting the new SIM. I spent 2 hours on the phone with AT&T support after the store said they couldn't help me. Pulled the SIM card out, restarted phone, put it back in, reset network settings etc. I've searched sammobile and I cannot find the AT&T firmware, only TMobile, Sprint, and TMK. I would sincerely be greateful please if anyone could help me by pointing me in the right direction for the firmware for this model phone.
AT&T doesn't make their firmware available publicly - for any device. I have a source who can get me Samsung firmware for any USA device - even AT&T. But he charges me for each one
I appreciate the quick response! Is there any option I have here? Could I try flashing a "U1" firmware to his phone then? He's currently on A526USQS4CVA6. I actually found your other post as I was also working on my note 10 plus - https://forum.xda-developers.com/t/n975u-and-n975u1-firmware-links-here.3957648/. If I'm reading that correctly, I should be able to correct? If so, how can I tell if the version I'm downloading is "downgrading the bootloader"

1. Yes, you can try flashing U1 if you want
2. You can't "downgrade the bootloader" - Odin won't let you.
3. In A526USQS4CVA6, "4" is the position of the bootloader level/revision/binary. Make sure that whatever U1 firmware you download also has a 4 in that spot and you'll be fine. (Or just get the firmware from Frija or one of the other similar firmware download tools, because those throw you whatever the newest version is automatically)

My AT&T N10+ N975U is running on Pie. It transitioned seamlessly with no changes made on my end. It was already using 4G VoLTE though. Same sim card.
I would contact AT&T advanced tech support as there may be an easier way.
4G VoLTE needs to be enabled in hidden settings.

Yup. But OP has a T-Mobile model that they moved to AT&T. There's also no guarantee that a Note 10+ will work the exact same way as an A52. You're also running 3 year old firmware, while OP is fully updated.
So i don't see the correlation.

The old firmware works fine on 4G VoLTE... that's likely not the issue. What is the issue is it wasn't running on 4G VoLTE so it's likely the settings and sim card need updating not the firmware.
Hi All, thought I would provide an update... After spending hours on the phone with AT&T support this week and being frustrated with the AT&T store, I decided to proceed forward with flashing the U1 version. What started this all was last week my son could no longer make or receive calls on his AT&T A52 phone (we ported it from TMobile September 2021). The store and AT&T advanced tech support said there were issues with people's BYOD devices, even though the A526U and A526U1 shows on the supported devices list. The store rep said he's been getting people in left and right that can't make or receive calls, and all they can do is upsell customers to an AT&T branded phone.
SO... my son's phone was on A526USQS4CVA6. Startup screen showed TMobile still, even with the AT&T SIM card in it. I proceed to flash the A526U1OYM4CVB2_ATT that I found from Sammobile. Was hoping someone had just the "U" version but I couldn't find this anywhere. When doing the flash, I used the Home_CSC file (I had to download a patched version of ODIN as it was stuck as setting up connection) and when it finished it would just keep going back to the download screen on the phone and I freaked out. I did some more research and decided to flash again using CSC instead of Home.CSC (I did a backup using smart switch on my PC luckily). This WORKED! I'm guessing because the software version he was on was different than what I was trying to flash too so maybe this is why I needed the CSC for a clean flash (there was no user data file that downloaded from SAMMOBILE).
Now, calls are working on my son's phone again! AND his service provider software version now reflects ATT vs TMB! Man this has been one heck of a journey lol. I've seen numerous forums on google of people having the same trouble with me, their BYOD devices not working. Seems a flash of U1 worked for me, so hopefully this helps others out there!
