Snapdragon s10+ with unlockable bootloader? - Samsung Galaxy S10+ Questions & Answers

Apologies in advance if this is a stupid question! Sadly I am nowhere near as knowledgeable on this as you guys, hence the question!
I currently have a UK bought Note 9, but I was looking to sell it for ~£400 and then get a s10+.
The one of the samsung website is £899 which is too much for me to justify an upgrade, but on the grey market with sites like this eglobalcentral
They cost around £659, much better.
I would also prefer the snapdragon version to the exynos version which we get here in the UK. Would I be able to purchase this one from the site, the G9750, and flash it with the bootloader of a UK version, such as the SM-G975FZKDBTU (SM-G975f)? Does one know how I could do this? I have realised some US versions you cannot unlock the bootloader, does anyone have more details on this? I can't find anything anywhere. Thanks in advance!
My priority of course would be not to trip Knox or void the warranty etc.

I use the SM-G9730 in Canada with TGY (hong kong) build. It's fine, not sure why you would prefer to change the bootloader.
Once you swap the system language to english, its all good.
Plus the bootloader itself is all in english.
The biggest thing is to make sure all of your bands match up.

A locked bootloader prevents you from installing anything other than the official flavor roms and kernel. So if you wish to install custom Roms like LineageOS or the like a some point you must have an unlocked bootloader or be able to unlock it.
That said you would not be able to install the firmware for the UK model specifically because they use different chipsets (Snapdragon vs Exynos). But rom itself should be basically the same and not need changed you would just need to install the specific apps you are missing. Usually those apps can be found in the play store.

[Q] About different N3 models

Hey people,
I'm planning on getting a galaxy note 3, but I'm kind of confused about the different model numbers (n9000, n9005, etc). I have read this post and it did help, but I'm still unsure of which model to get.
I will buy the phone in USA and bring it to Brazil to use it over here, so it seems the N9005 would be the best since it is the only one to support the 4G frequency used in Brazil.
However, it is written there that the N900W8 has a 'happy' bootloader (what exactly does that mean?), and I think I saw somewhere that the N900T was the best version for hacking. I'm more worried about having the best version to play with than 4G compatibility, but if the difference between models is not that big I will get the N9005.
So, what exactly are the differences between N9005, N900W8 and N900T and which version is the best one to hack around? Do all of them have an unlocked/unlockable bootloader?
I'm also worried about region lock, but if I'm not mistaken even if I do get a model that is region locked, it is quite easy to remove the lock and use it anywhere right?

I'm not an expert so this is my best understanding, but not solid certainty:
N9000 = no 4G/LTE. I believe they've managed to reverse Knox on this one.
N9002 = dual sim card support. Haven't heard much else about this one.
N900W8 = I actually have no idea what distinguishes this model... I haven't really heard of it except for reading that yes it can be downgraded from 4.4 back to 4.3 apparently.
N900P/N900A/N900T/etc = Different versions of the N9005 as far as I understand. Be warned that they support different 4G frequencies, and the N900P (Sprint) only supports 1 band in 4G. Check this before you buy. Frustratingly, the N900P is also the only version of the Note 3 that has a real, old-school, FM tuner built in.
N9005 = Seems to be the best/default that everyone goes for, but I might be wrong.

I think N9005 is the only one that will get LTE in Brazil. N900W8 is friendlier to hacking (knox can be easily fooled and downgrade 4.4 -> 4.3 is possible). N900T is more usable inside US on T-Mobile and AT&T.
The region lock might be a problem under certain scenarios - I think that RegionLockAway (needs root) might only work with older baseband (but I have not tested personally).
As a holder of an N900W8, I can tell you about the "happy" bootloader.
It is the only phone with an untrippable KNOX counter when trying to root or custom ROM on the latest firmware. Now you have to be on the Canadian version (not the Mexican version) and not attempt to downgrade the firmware or else you will trip it, but anything else would allow for rooting or flashing without breaking your warranty.
Hence this is the best for hacking. It has identical specs with N900T but that has a trippable bootloader.
They all have an unlocked bootloader except N900A or other American variants. You should look for a variant closer to your country so you don't have to worry about unlocking the SIM.

So it pretty much comes down to either the N9005 or the N900W8.
I don't really care about tripping KNOX since I will buy the phone with no warranty, is there any other downside to tripping KNOX than loosing the warranty?
Also, the N900W8 is better for hacking for now, but that is not because it is inherently better, it just happens to be better for now because someone found a exploit for that particular model, is that right? Or it is fundamentally different in a way that it will probably always be the most hackable model?

Then the knox-friendliness of the W8 is not so relevant to you.
The N9005 has LTE in Brazil, W8 does not.
IMHO to make the best decision you must investigate the region-locking and unlocking on both. I believe there is actually an N9005 that is supposed to be for the region of Brazil (so it needs no region-unlocking) but it might be only sold by specific carriers with LTE there.
I looked around and the N9005 is the version used in Brazil, and USA is in the same region as Brazil. So if it works in USA it should work here in Brazil too.
N9005 america region is it then, thanks a lot everyone.

What's the right variant to buy, PLEASE HELP!

Dear Friends,
I live in the US, using AT&T US, but would like to have the option to move to T-Mobile US or perhaps even Verizon.
Question is, what is the best S7 Edge variant for me to get, if I have the option to buy 935F and 935FD (I believe this EXACTLY the same as 935F except Dual-SIM or it's got extra bands I could use in the US?)
Here are my important requirements that would help you make a recommendation:
1. Root Support (I guess with little trouble as possible, I am seeing nightmares on people finally being able to root the US variants with the Engineering bootloader - Over heating, slowness, data issues, bricks, etc)
2. Xposed
3. TWRP for Nandroids, if possible?
4. Performance, Battery life
5. Samsung Pay (on a rooted device) if possible in the US?
6. Warranty - These are expensive devices, is it impossible to get Samsung support in the US with the 935F and 935FD model?
Thank you for your advice, help in advance, looking to make the decision in the next day or two. Thanks!
935F and 935FD are the exact same, except the FD has the dual sim - no other difference (4).
That being said you will want to make sure you know what carrier you are going to end up with before purchasing. Verizon's CDMA network is not supported by the international variants.
In terms of your important requirements - you cannot use Samsung Pay on a rooted device (since root trips KNOX). It's Samsung Pay or rooted phone, your choice (1,2,3,5). International devices don't get US warranty (6).
My suggestion is to go for the cheaper one. I bought an FD gold model on Amazon for $625 (and free 1-day shipping), which was about $50+ less than the F model. I could have gone on ebay and saved another $30 or bought a used phone, but not a bad price.

@shyam09 Thanks for the education bud, some follow up questions:
1. Does the FD model have less Custom Development/ROM support, compared regular F?
2. Is it true the FD has ALL bands possible, and F doesn't for LTE, GSM use?
3. Is it true FD has both the Exynos AND Snapdragon versions? What's the difference, why?
4. NO American variant is able to be rooted, WITHOUT the Engineering BL, correct?
5. NO unlocked Bootloader model has warranty in the US?
6. NO version works on Verizon AND has an unlocked Bootloader, correct?
7. Once rooted, Knox tripped, that phone can NEVER use Samsung Pay right?
8. Not possible to have Systemless Root or Root cloak to use Samsung Pay?
Thank you so so much for your help in advance! What's making me nervous is the no warranty and almost every other thread in the Q&A section is about bricking :'(!

*BUMP*... Anyone? ?
I'm pretty sure you can still use samsung pay even with rooting a phone. However while rooted you can not use samsung pay. The root method here does not trip Knox. I used it on my phone and Knox is still in tact. But like I said you have to unroot for Samsung pay to work again. I wish I had more information for you on the topic but I'm still fairly new to the s7 edge. Also the unlocked bootloader isn't possible as of right now.
Edit: hard brick is impossible because stock firmware is available to flash if anything goes wrong.

Get the F model from B and H. They provide a one year warranty. Done. The other answers can be found on the interwebs.

Guys, thank you for your responses.
If I'm not mistaken aren't the Exynos variants F and FD both Bootloader unlocked?
Anyone know if F has more development than the FD model or can they share all ROMs radios and etc?
No variant that works on a CDMA network in the US has an unlocked Bootloader, correct?
Finally, possibly may have a choice of getting the Note 7, would you guys think the Exynos models F and FD come with unlocked Bootloaders for better rooting and custom ROM options?
Thanks again guys!

G950U Version for all carriers in United States

Hello, I would like to know if I can flash my verizon galaxy s8 with tmobile software, or any other model, since I can see that this year all the carriers are using the same model G950U. That is, a single model with different carriers, very similar to how the international version G950F works which is the same model for all carriers in Europe and allows you to change the software through ODIN. I hope someone can help me. Thank you very much.

From what I've gathered is that there's a user data partition that dictates the carrier and Odin currently doesn't allow flashing of this.
Saw this as a comment somewhere here and best I've seen so far.
Personally I think it is just a matter of time before we figure this phone out and will be able to do whatever we want. They already have root for Exynos model and I think now the search is on for modified Odin, as Tehpirate said. I believe they had modified Odin for S7, to do similar stuff, so it's not like starting from scratch.
I hope is the same like the s7 U firmware... That's nice cause I can flash U firmware and get rid of the carrier bloatware.

Buying a carrier-branded S8 from another European country

Hello all,
So I'm tempted to buy a Tim-branded S8 on Amazon.it because it's crazy cheap currently. I'm not in Italy but from what I've gathered online (and confirmed by a review on the product's page on Amazon), branding in Italy doesn't mean sim-locking so it should be usable with my local carrier. I'm in Europe anyway.
The only major difference with an unlocked phone (since it doesn't seem to have any hardware trace of the carrier) will be the software : potential TIM-related bloatware, delays for updates, etc.
My question would be : could it be possible to flash an official "clean" image, without affecting the phone and its warranty ? If so, which reference should I use ?
Thank you very much !
Yes, was going to ask if it was also sim locked.?
What county are you in and what sim do you use?
Out the box, if sim unlocked, it will work anyway.
Unless you want any advanced features.
Fw wise it's not a problem. I went the other way though, flashing EE ( UK) firmware into an unbranded unlocked BTU version to get VoLTE to work. It caused no issues.
Belgium but I guess European models pretty much have all bands available across Europe...
Thanks for the feedback !
I have the tim s8 here in the UK, flashed the h3g firmware and have WiFi calling and volte functioning without issue.

hi
Im also interested in buying a tim branded phone (https://www.amazon.it/gp/product/B071RSVYSH/ref=ox_sc_act_title_1?smid=A11IL2PNWYJU7H&psc=1) and was hoping if someone who has one could answer me couple of questions.
1) Does the phone have universal warranty? I mean if something was wrong with it and it needed any repair, could I just take it to a local Samsung store?
2) The model number on amazon site is G950, is that different from G950F? i couldn't find any reliable info on this..
Thanks in advance!
If the phone is designed for the European market then warranty applies regardless where you are (within Europe).
All European models are F-models.
You can flash an unbranded ROM through Odin to get rid of any branding which does not trigger Knox.

Switching firmware for SM-G975U (need advice)

Hi guys, need some advice on S10+.
I'm from an Asia country and last year I bought a new S10+ from a online seller which does grey imports for mobile phones, because I want a Snapdragon version over the Exynos, which is what most Asia countries get.
The Model number (SM-975U) and Baseband version (G975USQS3CTB6) are indicating this is a US variant but I can't tell which carrier it is because there is no carrier logo on the phone or when I turn on the phone, no bloatwares as well.
The only down side is this Baseband/carrier does not have updates since March 2020. I tried checking for updates but got nothing.
What I try to get:
1. Latest original firmware which will continue to update itself (hopefully)
2. No carrier bloatware
3. No need root or custom roms (Doesnt go well with banking apps)
I have experience rooting and flashing custom firmware on my previous Samsung Galaxy S7 Edge, but I can't remember if I have done unlocking bootloader before, lol.
Need advice on:
1. Which firmware should I choose?
2. I remember XDA forums used to have useful Guide under Sticky Threads but now I don't see it. I hope this guide will be able to help me with what I am trying to do.
3. I probably sound stupid here, is there any flashable settings file that is friendly to Asian region/telco? I am noticing a bit of network weakness on my phone, I hope its just me.
Thanks to anyone who reads this.
You've aquired the US Unlocked Snapdragon variant, it's not associated with any US carrier and it's not bootloader unlocked. Flashing updated FW is likely your best bet, it's available here.

The only other option for an update is Samsung's SmartSwitch. Whether or not it's compatible depends on your local service provider.
