How many H815 versions there are and how to identify them?

I though that H815 was the european open version (able to unlock bootloader and such) and that the other versions had other names, but I've seen people about talking about H815 versions with the same name and with or without LTE-A, or even specific H815 versions for Asia, France or even non-carrier USA, and on all of them the bootloader is locked as ****.
Is this true? in this case, if you were buying this phone online, how to determine you're buying the european open version? what's the model name exactly for that?
Thanks!

I got mine from handtec.com. I made sure before purchasing that it was the H815 EU. That is what you are looking for. And as a note, I unlocked my boot loader 3 days ago so I know what they sell is the true EU version.

I got my H815EU from handtec as well. Unlocked the bootloader the same day.

Only way I know of is to check settings under software version. For example mine shows V10C-TWN-XX.

So when do you think we will be able to unlock the bootloader?

I'm also thinking the same thing here. ?
I have managed to root. But I need custom recovery just in case I need to back up etc

to see whether your model is unlockable - please see my post entitled [UNLOCK] list of LG G4 models that you can unlock

Difference between lg h811 and h815t?

So I opened my box today and realized the manual mentioned lg g4 h815t.... I have a h811
Looked up on website both are T-Mobile. What's the difference?
What phone do I really have?
Could I potentionally flash a h815 ROM?

The H815T is Not T-Mobile. The H815T are sold in Turkey and Hong Kong. It's mostly the same as the H815 variant.
If you flash an H815 firmware on your device if it's a H811 you'll permanently brick your device.

LG website states 815T is a T-Mobile phone.
It is possible the manual just has that model number listed and shipped with my 811 device.
How do I really check what version I have?
And why would they state 815T is a T-Mobile phone on their website?

I see no where on LGs website on the H815T page stating it's T-Mobile. If it does it's a glitch. It's 100% not a T-Mobile USA device.
Manuals may not matter as a G4 is a G4 operation wise.
What do you mean check which version you have? If it's a H811 then it's a T-Mobile device. T-Mobile only has 1 model for the G4.
Where did you buy your phone? If used/referb/second hand that might explain the manual mismatch.

Bought it through Rogers. Apparently rogers sells or sold h812
Box imei and serial number match to phone.
Must be manual...manual is a manual.
But why would Rogers be selling a T-Mobile phone.....when they have their own brand?
Anyway to check other than software?

Now that is what's odd. So you bought it through a actual Rogers store? And not a reseller that just happens to sell rogers stuff?
Rogers themselves I doubt would sell a T-Mobile device.

Glad I didn't get a 812 to be honest, read there are no custom ROMs?

It’s not that it’s not been tried. It cannot be done. If it is you’ll 1. Result in a brick or 2. It won’t work and hope that you’ll be able to flash it back.
The modems in those phones are completely different. Along with the T-Mobile model having antirollback which makes it impossible

Ok well I have the H812 with antirollback value 0. once steadfasterx is fully complete his unofficial bootloader unlock, my plan is to unlock bootloader, install TWRP, then until custom roms for this variant comes out, I plan on flashing other carrier firmwares.... and it seems H815 has better updates, so probably going to flash that one...
Also, can you kindly tell me what you mean by "modem" in the phone? is it the thing that deals with frequency bands?
If it softbricks, I can always re-flash my stock firmware right? What are the chances of a hardbrick?

H812 won’t be as locked down as the H811 is. But flashing wrong model firmware is a no no. Flashing custom roms built on another firmware may not work correctly but won’t be as harmful as flashing stock firmware which will 99% won’t work and or will cause a hard brick.

SM-G955U to SM-G955U1

I noticed after rooting that I went from firmware U to U1.
I guess my question is can I use normal Odin to flash SM-G955U1 firmware and have my phone unlocked so I can use my goole Fi sim card?

Flashing the firmware alone will not unlock the phone. You must have the carrier it is attached to unlock it first.

When you buy a Galaxy S8 Plus at a store in the usa like Best buy or other, you will get the model SM-G955U1 which is unlocked and it works will att and tmobile sim cards, i have that model and works fine with Tmobile.

You can use ODIN to flash U1 firmware for a bloatfree experience, but that WILL NOT carrier unlock your device. It has to be unlocked by the carrier. Either by calling them direct or paying for an unlock service. But if your phone is paid off, your carrier will unlock it for free.

That's a half truth. You CAN purchase the U1 model at Best Buy, but only if you specifically ask for it. They also sell the carrier versions for ATT, Verizon, and I believe Sprint.
The U1 can also be purchased directly from Samsung, as well as the carrier versions.
Yes the U1 works with ALL major US carriers. I.e. Verizon, Sprint, ATT, T-Mobile, US Cellular, and all their MVNOs.

You can try my post i would like to help you

I have the U1 and flashed U firmware, and was trying to go back to U1 and Odin is being a pita about it.
Any pointers on how to get my U1 phone that thinks it's a U now, to get back to being a U1? Get a binary error when I try. I have both firmware. U oddly says it's an XAS file (phone still shows being XAA, but U1 is an XAA file, both from sammob, and both are latest updates, Dec. 1st.).

If your getting a binary error either you are 1 of 3 things. Using older firmware than on the device. You need to flash the combination file then subsequent firmware. Like u1 combo u. Or u combo u1. Or wrong odin. 3.13b

Xfinity Mobile Note 8

Anyone have it? Anyone have any idea if it's the same version as Verizon? It's my understanding it's just the unlocked version. Open to flash any of the Qualcomm builds. But it runs Verizons network. Really just looking for any info anyone has on it.
Another thread about it got closed, but this is being posted in Q&A so this should not be closed.

i am working on trying to figure out which firmware can be flashed. and you need a unlock code for the sim lock

The Xfinity Mobile Samsung Note 8 (SM-N950U) is basically the same as the verizon branded phone. This means the bootloader is locked and will likely never be unlocked. This means you won't be able to install TWRP or load any of those custom roms
---------- Post added at 06:35 PM ---------- Previous post was at 06:32 PM ----------
You should be able to root it using the SamFail method but unfortunately there are restrictions
For example Magisk not working and it will fail safety net check.

Anyone with Xfinity Mobile who might be curious about doing this, I have successfully obtained root using SAMFAIL method... Follow his instructions exactly as written! When the device restarts after the second part of this tutorial you might end up with a blue screen that restarts the phone and flashes blue over and over, what I did next was I downloaded this firmware http://updato.com/firmware-archive-s...3AFA163EE8F90B and flashed the Home CSC file alone using the normal version of Odin 3.12.7 that is included in his post (with the Comsy version that was used in the first two parts). My phone came with original firmware so just a heads up. After flashing Home CSC, phone booted normally and SuperSU worked. Make sure you give everyone in that post credit for the amazing work with bringing us an option for root in such a short amount of time! If you have any questions please let me know and I'll help you as best as I can.

When info look at it, I'll pop in my T-Mo SIM and see what happens. If it's locked, I'm guessing I'll get the pop-up window to enter the unlock code.

It is the unlocked model, but it's also sim locked to xfinity. I use it constantly. It only comes with about 5 apps from xfinity and no other bloatware.

The phone is carrier unlocked but Xfinity has it SIM locked to their SIM. If you send them a message or call them however, they will email you a unlock code within 3 days. I have a few phones with them and this is what I did, they are all SIM unlocked now

Man this phone is so good without root I can't imagine rooting it. Between Samsung Themes, and Substratum my phone is totally themed out.

Using xfinity note 8 with oreo full version want too downgrade back too nougate.
Hello everyone first thank you for reading and commenting on my post.
I have a xfinity mobile devicè that originally came with nougate 7.1.1 and I flashed it by sd card flash. I have a few bugs like 1. Security notification that keeps popping up all the time.
2. When watching you tube after a while the app get stuck and usually just have too restart and then works fine till the next time.
3. I cant send messages with pictures or videos thru stock messaging app from samsung. I can send text thru samsung message app. So I downloaded the Verizon message app and it works fine using that app because xfinity uses Verizon for carrier service LTE.
I am wondering first what is the exact correct firmware for xfinity mobile on note 8.?? Where can I get it from?
( I know the original firmware had a "j" in it) for nougate 7.1.1
If I cant fue the bugs on oreo 8.0 full version "please tell me how? Then...Next thing is I have oreo 8.0 with samsung experience 9.0 can I and how do I downgrade back to nougate correctly but I tryed and was unsuccessful. I tryed downloading a firmware off the internet and storing it and renaming it on sd card so I can flash it while in dfu mode. But it didnt work.
So bottom line is if I can just fix those bugs and stay on full version oreo 8.0 then please tell me how?
Otherwise please tell me how and where I can achieve downloading the exact firmware build for my phone and the samsung experience 8.0.? I need too know if its possible and where too get everything from and instructions how? Thank you all my XDA friends

Xfinity Boot Screen After Unlock
I have a Xfinity Note 8. I paid to have it unlocked so I could sell it easier. I have flashed many S8, S8+ but no Note 8 or Xfinity. Typically after an unlock, with a new SIM it would carrier flash after reboot. This one does not. I used my sons Verizon SIM no problem but it still had the Xfinity splash screen and apps. Could I resolve this through flashing with oden? I’m afraid to try since this is the first Xfinity phone I’ve come across. Any help or tips is appreciated!

You would have to reflash the Note 8 with the carrier unlocked firmware. The one you would buy from Samsung where there would be no carrier branding you would get the firmware from XDA Developers and they would provide guys in tutorials and how to flash the non carrier-branded firmware to the Note 8

Using Samfirm, what region would I enter? OR, If I download from SamMobile, should I just use the USA version. I see mine SM-N950USQ3BRA6 listed as (Unknown).
I would like the phone to carrier flash with each SIM so they buyer won't be intimidated. With the other phones if done this with, usually other S8, S8+, I haven't had to do it but twice for AT&T S8's. For some reason those in particular will sometimes not recognize the SIM even after unlocking and flashing through SamFirm and Oden has done the trick. I'm sort of a newb. I used to flash ROMS years ago but recently find myself buying and selling for profit. Thanks for your help!!
I'll try later and post my results.

no.
non us models are signed with different keys so they will fail to flash as has always been the case as long as i can remember.
if somehow the bl is unlocked then thats a different story but dont get ur hopes up.

Hello..
I'm not sure I understand.. If you want an A50 with an Unlocked Bootloader.. why buy a "U" version? Why not just buy an "F" or "G" version?
They have the bands to work on T-Mobile and AT&T... and can be rooted.
You obviously don't care about having Samsung Pay.. so is it just you want to have Verizon / Sprint / Xfinity as your Carrier?
F and G versions are available for under $300.00 U.S.D. at Amazon and on Ebay.

You seem very knowledgeable on the subject whereas I know nothing... I only want to root my A505U so I can restore apps with Titanium Backup. Since it's not possible to root this phone, is there any other way to get full app data from an app from my rooted phone onto this A505U?

no.
non us models are signed with different keys so they will fail to flash as has always been the case as long as i can remember.
if somehow the bl is unlocked then thats a different story but dont get ur hopes up.

that's pretty vital information, i'm trying to figure out how to turn specific bands on/off and get bands to select over others. like the threshold. example. i'd like band 12 to be targeted before band 4

Like this kinda?

How to flash unlocked firmware
bbarnes1 said:
I'm considering purchasing an a505u, but want bootloader unlocked. Can I flash the firmware to a non us model with modded Odin, unlock the bootloader, and flash back?

First download this version of ODIN: https://forum.xda-developers.com/attachment.php?attachmentid=4952061&d=1581888388 (I used the newest 3.14.1 patched)
Then download this firmware file: https://www.sammobile.com/samsung/galaxy-a50/firmware/SM-A505U1/XAA/download/A505U1UES9BTI4/386407/
Download mode: Turn your A50 off. Hold power and Volume UP until you see second Samsung logo and release. Choose Download Mode (Last entry)
Extract files from firmware ZIP. Open ODIN as Administrator. Plug in your device. Choose BL AP CP CSC from firmware folder (Choose HOME CSC if you want to preserve your settings etc). Click Start. after a few minutes you now have an unlocked SM-A505U to SM-A505U1 device. This will allow it to work on other carriers such as Visible which is what I needed.
