For the S8, I read that the Snapdragon variants sold in China (and even HK) had unlocked bootloaders. Is that again the case for the S9?

Too soon to tell but likely yes.
Keep in mind however that those models are pretty much unpopular (no idea why) and rarely see any type of development. So you have an unlocked BL but nothing to flash which sucks.

I asked jesec, who developed the first custom ROM for the S8's Hong Kong Snapdragon 835 that very question a couple of days back and he didn't know the answer. Curious if Qualcomm has the unlockable bootloader on all 845 chipsets but I suppose we'll soon find out.

The only ones which will be unlockable are the ones we are talking about in this thread.
All the US and CAN snapdragons will be locked down tight and a waste of money if you want proper root, twrp erc. its so easy to buy exynos why bother with the snapdragon version unless your on cdma?

Yes, the Hong Kong variant SM-G9650 has an unlocked bootloader and Samsung Pay on that model works as well. We'll see custom ROM's available before too long.

Exynos doesn't have the exclusive US LTE Bands. For the S9 I see Bands 14, 30 and 71 are all missing. This is a major problem since the US carriers will be shifting more traffic onto exclusive bands.

I live in Canada so have no idea about US bands although i know they have always lacked some for Tmobile. Guys dont seem to have had issues running exynos in the US over the years though?
Ive never had any issues here with exynos at any rate
Hey, I *almost* pressed 'buy it now' to pick up an exynos S9+ to use here in the US on Verizon. Then something caught my eye about another listing saying "GSM Only". SO.... I surfed around a bit and found out the obvious: Int'l versions are GSM only, and Verizon's current voice network is CDMA. HOWEVER....I think I've also learned that VZ is phasing out CDMA in favor of using LTE for voice. In fact, they are hoping to have CDMA totally gone by 2019. In another thread on the S8., someone speculates they would have no qualms using a Int'l S8 on verizon since '98%' of their voice network is now LTE.
To complicate matters, this is a work-paid phone plan, so I can't install any custom ROMs- has to be stock.
So- is this doable or should I give up hope? (The reason I'm hot on getting the Exynos model is to use the dual-band GPS when the feature is unlocked, presumably in a future firmware release).
Thanks!
I don't know the time frame but they are certainly moving to GSM. I suspect that a large part is now GSM since they initially started in Canada and Mexico some time ago.

The exynos s9 may work on verizon LTE data, but not on calls. Currently Verizon has CDMA which doesn't work on the exynos s9. If Verizon switches to only LTE then the exynos s9 will most likely have to support Verizon's VoLTE, and VoLTE on the exynos s9 doesn't officially work on stock software with any US Carrier without hacks that would make the phone non-stock. So far the only working modded CSC is on T-Mobile and there is development on an ATT CSC. The snapdragon s9 has significantly better battery life and better performance than the exynos s9. The Dual-band GPS is something that Samsung might not enable. If you aren't going to use custom roms or unlock the bootloader because the snapdragon s9 doesn't have an unlockable bootloader, but the exynos s9 does then the snapdragon will probably work better in the US.
Thanks guys. Looks like I'll be stuck for now in my quest for <10cm GPS
Did anyone get the chance to see nomenclatures of US models? I'm mainly concerned about cross flashing, really hope it's gonna be possible this time around, unlike the s10 5g.
I think them days are long gone with the bootloaders been locked down for the US models
We've known the nomenclatures for a long time, ever since before the FCC filings. Standard Note 10 and Note 10+ will behave the same as Note 9 - crossflashing included. I've already posted both U and U1 firmware

10 and 10+, yes. 10+ 5g will only be Verizon as the radio is different and only supported on their network. So you can cross flash any Note 10 as long as it's not the 5g.
I know I am uneducated when it comes to these sorts of things and I apologize for my ignorance but if either of you could fill me in, I would love to know what exactly "crossflashing" is?

Flashing other carrier or unlocked firmware to your device since hardware wise there is no difference.
Example. On the note 9, ATT builds leaked early on quite a bit so if you wanted the latest before it was officially released you could flash it to your device as long as it was the same processor.
Even applied to the Pie beta that released for the unlocked models.

I attempted this on an S6 and could never successfully get the modems/radios to right... or maybe I had the data misconfigured? Who knows... but that is remarkable! If you don't mind me asking one more simple question, does this trip knox? Because I'd love to have the unlocked firmware on my VZW but I'm not sure of any specifics on the warranty. Although, I know if I ever DO have to send it in, I'll just brick it from the inside with wrong firmware.

Nah. It won't trip Knox since the firmware being flashed is signed by Samsung.
You can always flash back to stock as well. Stock in this case being the software it shipped with.

S6s are not cross-flashable. Samsung didn't start that until the S7 and Note 8
it would've been awesome since in the FCC docs shows that N975F (Exynos LTE) and N976B (Exynos EU 5G) have identical hardware!
also Verizon is using the SAME SKU model codes for both LTE and 5G models
i posted the details in reddit earlier (r/galaxynote10 titled "Crossflashing LTE <-> 5G Models?" sorry i can't posts link....10 post count thingy)

1. N975F and N976B can't have identical hardware. The 5G model has 5G antennas, and the 4G model does not. I can guarantee you that firmware will not be cross-flashable between those 2 models.
2. Verizon is NOT using the same SKU codes for the 4G and the 5G models. The 4G model is N975U and the 5G model is N976V. I can guarantee you that firmware will not be cross-flashable between those 2 models.

I could not possibly be eyerolling any harder right now.
I'm sure that as far as the 4G hardware is concerned, yes, most of it is the same, same location, etc. But the FCC IDs for the 4G and 5G models are NOT the same. I promise you that the 4G models do NOT have a 5G antenna, and you will never be able to flash 5G firmware to a 4G device.

That's what I suspected initially, is that they meant the hardware is identical in the scope of that report, in other words, "as far as LTE is concerned". especially since the 5g chip is external to the SoC.
About verizon, to be clear, am not mindlessly hoping for a "free 5g", as clearly its not the case in hardware; but how would you explain Verizon using SM-N976VZKAVZW for the LTE SKU and SM-N976VZWAVZW for the 5G sku? is it simply a typo in samsungs' support website?

Yup. See all the other SKUs for the 4G N10+ on that page? They're all N975U

Hello guys, I have a chance to buy a cheap sm-n976v with bad imei. Phone is locked by Verzion. I'm living in UK and I wonder if I flash the phone with sm-n976b firmware can I get it unlocked and fully working? Sammobile said that should be exactly same model. What is a difference between V and B firmwares? Or is better to pay for unlocking the phone instead flashing it? Can I flash it with European version without broke it?

You cannot flash any other firmware to that model - and even if you could, solely flashing firmware would not SIM unlock it. I can give you a recommendation for a 3rd party unlocking source if needed
Probably that will be better in this case. Thanks
Im using the 975F on ATT at the moment. the 975F is missing band 30, which ATT uses in cities. It is a real headache. Signal is poor, data speed is sometimes non-existent etc.
I notice Sprint and Verizion's LTE bands are all covered by the 975F. At the same time, the 3G bands are not. I am interested to know if anyone out there uses the 975F on either Sprint or Verizon, and what the experience is like.
thanks
I'm using SM-N975F/DS SIN on Verizon with no problems
Really? without any issues at all? LTE works fine? Because it is the exynos version I thought it wouldnt work with the international version

The International Snapdragon variants have a better SoC however being in Denmark you won't get some Carrier Features the Exynos variants offer, that's the trade off.

I have the Hong Kong variant on T-mobile. Advantages - Snapdragon SoC, no carrier bloatware, close to pure android, dual sims, unlocked bootloader, price ($745 on eBay). Disadvantages - Warranty repair would be difficult, no 5G yet or carrier aggregation. Highly recommend, my S8, S9 and S10, all Hong Kong variants, never had any problems whatsoever.

Not to me, I typically download large files on my laptop via WiFi then transfer them to my device. I'm a frequent flyer so I watch movies (torrents) which are typically 2GB. Not sure how long that would take to download on my device via T-mobile but it's not significantly faster than WiFi. When mmWave is widely avaliable Carrier Aggregation will be more valuable but right now High-band 5G is comparable to WiFi file transfer speeds. That's a small inconvenience compared to the benefits the device offers.
@varcor did you change the CSC to see if CA works ?
I'm assuming you're on TGY. I'm also in the USA and think changing to BRI might increase ca bands.

No, my CSC is TGY. I live in Mexico but use T-mobile since they offer free calls and data in collaboration with Mexico's largest telcom Telcel. Even when I'm in the US I don't have CA. I haven't gone to T-mobile to ask if they can configure CA but I doubt they can on the SM-G9860 or SM-G9880 regardless of the CSC. I use a laptop with Wifi for large downloads so it's not a priority. I do get Wifi Calling and VoLTE even in Mexico, YMMV depending on your service provider. Also I've read BRI has some issues so I'm not inclined to make the switch. This thread may give you further insight.

That link is google amped , perhaps you can edit it to make it viewable, thanks.
I was just curious to know if someone had changed their CSC to BRI and if it enabled CA.
I believe the first thing to be gathered is what bands are CA enable on the BRI CSC before even proceeding with anything else.
Also before flashing to attain CA I think one needs to compare tgy and bri CA combos.
Edit. Read that already, mainly non americans discussing attaining 5G on their respective countries.
