Flashing international Firmware

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.

If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??

I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.

...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

LG G6 Using different KDZ's

I'm new to the LG Ecosystem and I have a few questions.
I have an LG G6 H870 from Entel in Chile, its currently on Android 7.
1) Can I flash it to something like the OPEN EU images which are newer?
Because they're all H870's are they the exact same hardware, meaning the functionality on different H870 kdzs should work fine? The Entel doesnt even have a 2018 release yet so I don't have great confidence they will update the LG G6.
2) Does flashing a KDZ affect the boot loader?
If I unlocked the bootloader for rooting would flashing the KDZ back reset it back to locked?
3) Is it safe to flash a KDZ via a virtual machine? The LG Bridge app wont detect my phone on Mac no matter what I try (High Sierra), (adb is fine iv tried the drivers etc), however it shows up when I connect it to a Windows 7 VM.
4) Is it likely that when the official Oreo 8.1 update comes it would be better to switch to something like an OPEN EU or UK image?
Or even just flash the new 8.1 KDZ when its available?
5) If I rooted and flashed something like LineageOS, can I easily go back to any of the KDZs with the LG tool?
I noticed theres an "error link which seems to download a KDZ for resetting your phone. Does that work off some kind of internal hardware serial, meaning that if things are ever soft-bricked I could just hit that button and go back to square one no problems?
6) Anything else I should be aware of or concerned about if I want to play with flashing different KDZs or custom roms? I dont care about warranty e.g. unlocked bootloader.
7) Whats the best tool for unlocking bootloader and gaining root these days, I know theres a tonne of AIO tools and things like KingRoot. Any suggestions from other LG G6 modders?

1) If it's just an "H870" than yes, it should be fine.
2) You cannot unlock the bootloader. Only unbranded US997 and European H870 can.
3) Never tried, it should, but in this i cannot give you a certain answer.
4) 8.1? We don't know it'll be 8.1. Anyway it's always better to flash the right firmware for your region.
5) You cannot do any kind of modding on your device atm, see the 2nd answer.
6) Flashing a wrong kdz could hard brick your device, so be careful on names. For the warranty you're good to go, you cannot do any kind of modding.
7) For G6 there is no "best" tool, there is only ONE way to unlock the bootloader but it won't work on your model (as explained in the 2nd answer), other tools like KingRoot don't work at all.
Bonus answer: No, flashing an european firmware won't allow you to unlock the bootloader.

Sorry for the noob question, it's probably been asked on here, but have not been able to find a solid answer. I have a US Cellular LG G6, which by now I know bootloader can't be unlocked. But, is there any way to update to Android Oreo? Currently on Android Nougat 7.0. thanks in advance.

I have found out the hard way that there are several versions of the model US997 variant of the LG G6:
https: //lg-firmwares.c o m/lg-us997-firmwares/firmwares/
(I apologize that the forum's spam filters are preventing me from posting a working link. Just take out the spaces.)
There is a USA unlocked version, two US cellular versions, two "Brightpoint" versions (whatever that is), and an Amazon version. And they all share the same model number. This is quite confusing because with most phones, usually there is only one version per model number. If your phone is stuck on Android Nougat, chances are you're like me and you're on the USA unlocked version of this phone, not the US Cellular version. The US Cellular and Brightspot versions have all been updated to Oreo and the latest update was in September 2018.
I have no idea why LG isn't upgrading the USA unlocked version. It was very frustrating when I bought it used and found out it was still stuck on Nougat, which I was not expecting.

Just use the US997 and NOT US997U and it'll work perfectly on non-US-Cellular or US-Cellular KDZ. 21B is latest Oreo

Actually the US Unlocked version has gotten the update and it's bootloader unlockable... My phone is the US997Z which is the US Cellular version. I believe you have to be connected to their service to be able to receive the update through their towers. I went ahead a upgraded my LG G6 with the US unlocked version kdz as the @HueyT mentions above. Update went great using LG up and uppercut no set back going through the update. If you need help I would happily help you out. Because I was in the same boat as you.

It's very strange that some versions of the LG G6 "US997" are not updated to Oreo yet and other ones with this version are. But if there is anyone out there reading this, you know know there is a workaround and you can force your computer to update the firmware on your LG G6 with the official LG ROM that runs Android Oreo.
For the $254 I paid for this phone used, with a case and the original charger, I can live with a phone that I have to update manually if I won't get OTA updates for some reason. And I did not break the phone's security because I'm still able to use Google Pay and online banking.

TMobile Software Download?

Is there a way to get the newest version of TMobiles Oneplus 6T software downloaded on my device? I have the TMobile variant now and I need to use the Unlock app to unlock my phone because I just finished paying it off. The TMobile software comes preloaded onto the device but now I no longer have it. I wanted to know if there is A. a way to download the Device Unlock TMobile app or B. downgrade to a TMobile software version. I turned my device into an international version.

Unlocked AT&T S10+, can I flash it with a Tmo ROM?

This may be a rather basic,question, but I'm trying to play it safe so I don't brick my S10+ (SM-G975U). Can I download an official Tmobile Android 10 ROM and flash the phone with it? The phone is not rooted and the bootloader hasn't been touched (at least by me).
I purchased an unlocked AT&T device and use it on Tmobile without issue. I am not, however, receiving any updates from AT&T or Tmobile, so I'm looking to update to Android 10.
Is this possible?

Yes, you can take any official carrier firmware made for the phone and flash it with the patched version of Odin. The bootloader has to match though. If you're on bootloader 2 you can't flash a bootloader 1 ROM. You can even flash the unlocked Samsung U1 firmware. You can also jump from Android 10 back to Android 9 and then back to 10 as of late. The phone can't be rooted nor can the bootloader be unlocked.

Bootloader version
Thanks for the quick reply and I appreciate the guidance. How would I know what bootloader I am running on my device currently and what version of bootloader the ROM is?

No problem. To find out your bootloader go to settings, about phone, software information. Look under baseband version and you should see "G975USQU2CSKP" or something along those lines. The 2 right before CSKP is your bootloader version. If it says 1 instead of 2, then you're on bootloader 1.

I tried to use MSMDownloader but when I hit start I get the error "images do not match with the phone"

What version of MSMDownloader are you using? I'm assuming you are using a T-Mobile branded 6T, as I get the same issue with the global packages. Try following this guide and using the 4.0.58 version and it's patch. That should let you get around the error.

That I do not know, but it should allow you to flash any fastboot images as if it was a unbranded version. If that does not work then I'd try some of the Android 9 versions of the MSMDownload tool.
