J727T Unlocked, No Service. Help Getting Unlocked ROM - Samsung Galaxy J7 Questions & Answers

Hi there! This is a bit of a stretch, but I have a T-mobile phone, that is unlocked, and im trying to use it with a Canadian Carrier. I had an issue with a T-Mobile S8+ a little while back, that was solved by loading an Unlocked Stock Rom onto it using PrinceCosmey's ODIN. I am looking to do the same here, but am unable to find the STOCK ROM UNLOCKED anywhere. lots of custom brands, but nothing stock.
The Rom would need to follow these things.
Compatible with J727T
UNLOCKED
STOCK
The last ROM i got was from UPDATO, but when i search for the new ROM in their website, it gives me an option of about 8 different basebands, none of which match mine.

[Q] S6 variants - which firmware/modem/bootloader is interchangeable?

I'm not as concerned about this for ROM flashing. I'm wanting to find out if my G920T can use G920I or G920F modems/bootloaders, etc.
Here's my deal. I have a T-Mobile G920T. To unlock this phone I need to get away from the G920T modem. I previously had a G920T1 (MetroPCS) firmware set installed and it worked great, but the rom sucked.
I've since restored back to stock G920T and i've rooted/twrp, but I see other ROM's and I'd like to give them a shot. The catch - they all say I need to have the newest OI7 firmware installed. I'm still on the G920T sim locked OH8. The only OI7 modems/bootloaders I can find are for the G920F variant. I can't find OI7 for the G920T1 variant. I don't know if the G920F variant will sim unlock my phone. I don't want to brick my phone to figure that out, so this is the reason why I posted this question. I can flash ROM's all day long, but if I can't use my Cricket sim when I'm out in BFE then the ROM is pointless.
Does anyone understand what I'm asking?

DO NOT flash any FIrmewares through odin if its isn't your model number, if you purchased your phone and don't have an EIP you could sim unlock with the app, so any rom your on unless its not Touch wiz based (aren't any available besides touchwiz)

[Q] HELP G920T flashed wrong carrier stock ROM

I recently received a T-Mobile Galaxy S6, and it was rooted and had a custom kernel, which was a complete mess (the person who owned the phone previously clearly did not know what they were doing) so I just wanted to restore it back to full stock.
I am decently experienced with ODIN, rooting, custom firmware etc, but I have just done one of the biggest rookie mistakes I have ever done. I had accidentally downloaded the most recent firmware for my G920T, not realizing that the file was not for T-Mobile. It was the (XAR) carrier (I believe that is C-Spire but i could be wrong) and the latest was PK1.
It flashed perfectly and all seemed fine until I decided to unlock the device. The T-Mobile S6 requires the use of the "Device Unlock" app and since I had flashed the wrong ROM, the phone thinks the Device Unlock app is not compatible. When I put a different GSM SIM card in the phone, it prompts me to use the Device Unlock app.
I do not have a previous NANDROID backup from the original T-Mobile ROM, and now that I am on the lastest Bootloader for XAR, it will not let me downgrade. I have tried flashing pretty much every MM bootloader and TWRP for both T-Mobile and XAR and none will work (except for what is currently on the device of course) I always get the error "Device: 5 Binary: 4" (sometimes the binary is 3, depending on which version of MM rom or BL I try)
To sum it all up, I am on PK1 (latest for XAR) and I need a way to get back to the official T-Mobile ROM (latest is PD1). Is there a magic method to get this figured out or am I pretty much stuck with what I got until T-Mobile releases an update that is PK1 or higher?
Thank you in advance to all of you that take your time to help (and I am sincerely sorry if I am posting in the wrong section)

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

Should I flash my Galaxy S7 Verizon to stock firmware in West Africa?

Hello.
I have a Galaxy S7 that I got about 5 weeks ago. I paid to have it in the box but the person got a secondhand one. I am in West Africa but someway somehow I got a Verizon one that is unlocked for any carrier. Anyway I checked and some functions were not working. Private mode is not working, there's no software update option anywhere (I checked developer mode) and some features I've seen on YouTube are not even on the phone. I'm stuck on Android 6 and can't update so I made up my mind to flash a custom ROM but turns out Verizon's bootloader is locked which will make such a task impossible. Some days ago though, I found out that official Verizon ROMs can be flashed without unlocking the bootloader and this raised some questions which I want to ask here.
Here's the info at the about phone page
MODEL NUMBER - SM-G930V (there's Verizon on the back of the phone so I think this is true)
ANDROID VERSION - 6.0.1
BASEBAND VERSION - G930VVRU4API3
BUILD NUMBER - MMB29M.G930VVRU4API3
1. Can I really flash a stock Verizon ROM for the Galaxy S7 without bricking my phone and with a locked bootloader?
2. If I were to flash a stock Verizon ROM will the phone be locked to Verizon again? I'm asking this because this is the only phone I have and I'm supposed to use this for 2 years!
3. Should I flash the same baseband version or will another Verizon one work?
4. If all the above questions are true, where can I get official Verizon stock ROM for my device?
If you have any questions for me please let me know.
Thanks

Yes, you can flash Verizon stock firmware without issues, as long as you are not trying to flash an older Verizon stock firmware than the version you already have. In other words, you can upgrade, but you can't downgrade.
As for flashing a west African firmware, Nn, Verizon devices have a locked bootloader, the locked bootloader will not allow you flash anything except Verizon stock firmware. Attempting to flash anything from another region or from a different device will only result in a soft-bricked or hard-bricked device. You can only flash the Verizon stock firmware for your specific model number.

Hi! Thanks for replying! So where can I get a Verizon stock firmware that is an upgrade of mine and what region should I download from? Also which version of ODIN should I use?
Thank you very much!

Question Change Stock Firmware for T-Mobile F711U/1 US FLIP 3?

Hey folks, recently picked up one of the Flip 3s from T-Mobile on their magenta plan thing. I have desperately been trying to figure out how to change the stock firmware so I could hopefully root it, but nothing is working so far. I'd settle just for being able to change, not root at this point.
Using ODIN I've been able to flash different versions of the T-Mobile firmware, including from what I think is F711U to F711U1 and even a USC one I think, but any attempt at flashing XAA fails and I'm not sure why.
Does anybody know if it's possible to install non T-Mobile stock rom on this, or better yet, also root it?
Thanks in advance if anybody can offer any advice.
are you trying to unlock it?
i’ve got the device in the same plan too and looking for a way to unlock it so i can use it with another SIM
яno such an experience, but it could be useful for me. I am waiting for some competent answers here
Last I've read samsung locked us out. US devices cannot be unlocked
I used ODIN and flashed the Thom Browne firmware to my T-Mobile locked Z Flip 3 and even flashed to the Android 12 beta.

What ODIN are you using and I'm assuming it is on Bit 1?

I had accidentally gone up to bit 2 but using an odin that let me flash regardless of model mismatch I managed to get the most recent version of the stock firmware on it anyway. So now I no longer have to deal with the t-mobile bloat on top of it at least.
It's sad these things probably won't be rootable for a while but I can at least live with that.
Ok so you got it to U1 then?
