[Q] S6 variants - which firmware/modem/bootloader is interchangeable? - Galaxy S6 Q&A, Help & Troubleshooting

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)

Possible to flash unlocked Samsung Galaxy S6 G920A (AT&T) to G920T (T-Mobile)?

I own an unlocked Samsung G920A which I actually flashed to a G920AZ (Cricket Wireless (who is owned by AT&T)). I now want to flash to T-Mobile as I want to be able to 1. get Marshmallow. Cricket may never. 2. Be able to use WiFi calling and you can only do that with the TMO image (from what I read). I downloaded the G920TUVU3EPD1_G920TTMB3EPD1_G920TUVU3EPD1_HOME.tar and using Odin tried, but it fails.
Is it possible to flash to the T-Mobile firmware/ROM ?
If it is impossible, then I think I would want to go to the G920A again to get Marshmallow 6.0.1, then simply pop the T-Mobile SIM in, update APN, etc. Unfortunate though as the LTE bands all work. Seems sh***y it wouldn't work to use their firmware.

Flashing G930A ROM?

Currently have a G930T on ATT sim thats rooted and all (bought it because I though it would have an unlocked bootloader lol). I wanted to flash this G930A rom http://forum.xda-developers.com/att...30apf2stockdeodexeddebloatedrom-7-12-t3417012 because I wanted the AT&T wi-fi calling and video calling to work.... I've seen in another thread that the firmware between G930T and G930U has different bootloaders currently? Is this the case between the bootloaders of the G930T and the G930A as well? Also, does anybody know how I can find which bootloader I currently have?
Thanks.

Flashing different model firmware onto G930VL

Hello,
I bought a G930VL (Straight-Talk) S7 a few months ago, but I'd like to use it on a different service, specifically ting, to save money.
I have read about others flashing the G930V firmware onto the G930VL and successfully using the phone on Verizon.
I'm unsure of what model firmware to flash however to make it work with ting (G930V vs G930U vs G930F), or where to find a guide I can follow to go about doing this.
Thanks for any help,
Matt

All I know is the U software is way better after ya locate a way to unlock the bootloader on the phone so it wouldnt interferes with other security part and lock ya from using it at all bricked software iv'e done it with a galaxy proclaim a while back and I really love it without cell service preinstalled locked bloatware tht ya cant completely uninstall em but uninstalled updates for em and disable em is comes close to u firmware

[FIRMWARE] G950U1 Unlocked AT&T QK2

As of this writing (11/29/2017) this is the latest firmware for the G950U1 att unlocked S8 . I'm leaving this here for reference so people can return to it if/when they need it.
Download, extract, remove .md5 file name off the end of each file, flash.
G950U1UEU2AQK2 (This WILL update your bootloader so after this, no going to QH3 or before. Not that you'd have a reason to)

you donnt need to remove the .md5
you will need modded odin though.

You don't need to no, but it speeds up the process. I'm just posting firmware not making a hand holding tutorial. There's enough of those around
Thanks Joe I was tired of returning all the way back to the beginning and getting all those new updates on my unlocked S8

If I flash unbranded FW on a carrier specific device, loke tmo or att for example, would it sim unlock the phone?
If I flash tmo FW on an att s8 would it in turn allow me to use the att original device on tmo? I ask these questions because I feel like it would work for both my questions since flashing the FW flashes both boot, kernel and baseband/radio. The which is needed for signal. Just some theories but would love to know the answers.
Btw, I have a F model S8+ and was planning on buying some US branded devices so I was curious.

No, it will not unlock the phone (Note: Verizon phones are factory unlocked and remain that way after a firmware flash)
Yes, you can flash any carriers FW to a US S8 and use it with a different carrier.
So I understand, your saying if I flash att FW to a T-Mobile s8 I can use it on tmobile? If that is the case, to me that's an unlock of sorts tiny book lol. Just wanna make sure is all

You can flash att firmware and use it on TMobile but it will still be locked to TMobile. Just running att firmware.

Just realized the typo.....what I meant was, if I flash ATT on a TMO variant I can use ATT while locked to tmo? I'm very unfimiar with combination fw and always opted for the UK models for alot of reasons. Sorry for the confusion of my op question. I know on the s7 and edge if you flashed the US unlocked firmware it not only removed AOL bloat but it unlocked the device. So that is why I ask.

I had a TMobile S7 edge and flashing unlocked firmware never unlocked the device. That's handled by TMobile servers so...
Flashing unlocked firmware will give you just that. The smoother, bloat free firmware from another device but not the actual sim unlock.
I bought an unlocked device and wanted wifi calling so I flashed the g950usqs1aqf7 att firmware with Odin and it worked to enable wifi calling but I'm unable to get any ota updates and I hate the bloat. Is it possible to get WiFi calling with an unlocked firmware like this one? Also what is the difference between the U and U1 firmware variants?

There are plenty of threads on this, but I don't think anyone was ever successful. I flashed att Oreo to my u1 and got the options, but can't get my company to change my imei back.... My personal phone sim works fine. Quit at that point since it's an Ims registration error. You can try merging the wifi calling apks, but I'm pretty sure it's baked pretty deep in the os. The Verizon guys got some of it working. You can try their threads and see if any of it applies to us.

Thanks. Some threads made it sound possible but inconclusive. I'll just assume it doesn't work.
BTW, can you link to the att oreo fw? And what do u flash that with Odin or comsey?
The thread right below this one entitled Oreo ota has all the details and it needs to be side loaded through adb. Not Odin. But you will need to Odin the 950u base to get off u1

Ok thanks. I need to flash anyways because I'm having terrible battery issues and just debating whether to go to a newer version of 950u or back to U1 and losing WiFi calling. In your opinion is oreo beta worth it
So just to confirm, I have read everything, but I am just a bit confused. If I flashed the unlocked firmware via modified odin on a locked AT&T S8 it will remove a lot of the carrier bloat and give my my wifi hotspot back, but remove wifi calling. Similar to when I flashed the T-Mobile firmware on my AT&T S7 and got rid of a ton of the AT&T bloatware but was able to activate my wifi hotspot but lost wifi calling. I stay locked to AT&T which is fine that is not my purpose for flashing

and can you re-upload the link is dead now
The links don't work. Any chance you've still got the firmware? I've been overseas since october. I have an unlocked AT&T phone that I intend to keep using when I get back, so I want to keep it AT&T FW.
Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?

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
