So many variants, so much confusion.

So I will begin by saying that I own a SM-j700p, a Samsung j7(j700p) threw the carrier Boost Mobile. I noticed that that some variants come in different sizes, different amount of ram or what not, does this change the model number? Also certain models come from different countries, does this change the model number, or are the wide varieties of model numbers because of different countries different hardware configurations, also coming out at different times. I noticed for instance that certain roms will come out for one model variant but it can also be used for other models aswell. Perhaps I just want to save myself some time and hopefully help others save a bit of time, how many different j7's are there, which ones work together, or shall I say contain the same processor which I'm thinking is the biggest deciding factor in whether or not they work together or not. Ids there a website that contains them all and specs and what not. Thanks

Exactly the question which needed to be asked..
Sorry i cant answer it... except i can say us boost users are few with little in the options area...

I believe by the Boost website you have the J7 Perx (2017) model...that one is the only listed. I believe the model number is J727. I own the Sprint variant (J727P)http://www.phonescoop.com/phones/phone.php?p=5370

Correct, but that must be the current listing. The phone I have I bought at the end of '16 and is the sm-700p variet. This is why it gets so confusing. Perhaps someone or maybe I can if I get a few minutes to make a complete listing of all the j7.
**Edit; From my understanding it is primarily the chipset that makes the difference in whether or not certain roms will work across different variants. Is that true?

yes, the soc is the main difference http://www.gsmarena.com/results.php3?sFreeText=J7&sMakers=9 these are the various J7 models excluding the Perx or 2017, which the specs listed are wrong (it has a Snapdragon 625 soc, not the exynos)

The Galaxy j7 (2017) I have is from AT&T and the chipset is one from MediaTek, the model number is SM-J727A. What model is mine?

Canada/US Snapdragon or Global Exynos?

I am reading that people are really disappointed the Global version is Exynos based and not snapdragon but my requiremetns are these
I need it rooted, after I found out that S8 Snapdragon had no root for longest time - and even now the solution is not good, I was totally put off by Samsung
I understand Exonys versions have root come out fairly quick
I need to use Samsung Pay or Google pay( which If i am not mistaken can be done via Magisk? ) as its currency not possible in S8 or S9 Snapdragon due to its rooting method
Dual SIM - MAIN Reason - I beleive US version wont have Dual and Exonys wil?
Bring out the inner artist in doing some sketching
So considering he above, is the Exynos chip t hat and compared to my requirements above?
Any other recommendation? seek Note 10+?

Hello, on all that i still suggest you using Snapdragon version. As far as i can see you need root for custom rom. I have rooted Note 10+ (Exynos) and going for also Note 20 Ultra Snapdragon, since the Exynos is still prone to overheat and underperform. I dont know which is having dual sim and which not, but as far as updates go Samsung change their game... official updates are really fast they even announce 3 year support with updates. Rooted phone i think it means so much less now since google is closing everything good about it. Thats my opinion. And from my Exynos 9825 there is 33% performance increase on Snapdragon where Exynos is only about 15%. And i am from Europe and i feel offended by Exynos...

It is my understanding that the South American and Hong Kong varians twill be Snapdragons with an unlocked bootloader. Although they can be rooted, traditionally development might be slow on these variants.

the Korean versions are snapdragon this year also which is new since they have always been exynos.
i may go this route since the idiots at samsung only have the 512gb version in black in Canada and the US.
they are so stupid...did the sme thing last year with the 10 plus..only 512gb in black.

Here is a question, is the model/variant: SM-N9860, will it come in 512GB / 12GB RAM / Dual Sim (is it dual physical sim or hydrid dual sim - 1 slot for SD/Nano SIM & and 2nd slot for Nano SIM), and it will be the snap dragon variant with unlocked bootloader.
Also, will these models support Canadian Telcom's 5G network?

Problem in ROM region

Hello
I have a note 20 ultra bought from korea model N986N snapdragon international version, the problem is that I have several applications like the weather opens in korean language and several others, like samsung pay I can not use it (just in korea) and also the ESIM even I do not have the management option for the SIM card.
My question is, can I modify the rom so that I can mostly use samsung pay and ESIM or not.
Thank you

Good day, Guys.
I, too, bought my Note 20 Ultra 5G SM-N986N, Korean model, and I've been learning and tinkering with it for the past 3 weeks. So far, the only thing that is not working like it did with my Note 8, is the Samsung Pay. Now once I start the app I receive the error message "Couldn't read SIM card's phone number." I've been using the Galaxy Note since model Note 1, and I have had no problems with any model prior to now.
Since the Korean and US models are virtually the same, they both come out of the box with the same specs, sans-serif, the display (120Hz > 90/60Hz), memory size, etc., is it possible, or not advisable, to flash the ROM version that matches the US version?
Thank you. Cole

You can't flash the usa firmware on the Korean model.

No 3.1.1 on F916U or F916U1? (US variant)?

F916N (South korea), Canada and several other regions have gotten 3.1.1 3 days ago. Still there is no 3.1.1 on US variants.​I see that F916N is also SD865. Can we flash that on F916U/U1?

No. Different model number, Different model. Just because they have the same processor doesn't mean they are identical. Be patient, it will come to the US.

F916W is candian model. with slightly different LTE bands and that too got update.

So W models are the only exception to the rule. I didn't know if they still made W models honestly.
So U, U1, and W models are all cross compatible with software as they are 100% identical hardware-wise.
If you have some time, go check out some of the old Note or S series threads. Like starting with S8 and Note 8. There's a TON of good information about cross flashing devices, what works, what doesn't, what will brick your device and set your house on fire, etc...OK no fires, but Def bricks.
Some minor things have changed over the last few years, but it's all still good info about compatibility.

I flashed W without any issues. Works perfect

I uploaded 3.1.1 Odin files for the U model back on the 1st

Question SM-S9080 (China) bootloader inquiry

I see that this specific model (Released in China) I believe has support for custom ROM's one would assume the bootloader can be unlocked which would be quite surprising since this device carry's the snapdragon chipset which is used in US/CA models and is not able to have the bootloader unlocked. If possible could someone with a device please confirm as these variants are actually 300$ cheaper than the US/CA models and other Global variants. I can't imagine there would be any significant differences otherwise aside from the firmware would be China based and I might need to flash my own CSC package.

You can check in Settings - Developer Options - OEM Unlocking to see if your bootloader can be unlocked.

I'm aware of how to check, when you are yet to own the device then someone else would need to provide the insight. It's not exactly fesible to check another country's device and I'm sure the return policy is a bit harder.

You seem to be confused. You stated "the bootloader can be unlocked which would be quite surprising since this device carry's the snapdragon chipset which is used in US/CA models and is not able to have the bootloader unlocked". Just because the SoC is a Snapdragon doesn't mean the bootloader can't be unlocked, they've been making them for years. I own the Snapdragon device with an unlocked bootloader. So if you know how to check if you can unlock the bootloader why ask anyone else if it's possible? Don't be surprised if you can't flash different firmware, SM-R908N is an outlier but it can utilize Custom ROM's.

I will confirm that the Korean snapdragon note 20 ultra could be unlocked.
Rom support was slim though. Most did not explicitly mention the N model and since more people in the world are unlocked on exynos, most of the support was for that chipset.
Also the fact that snapdragons are locked in NA is because of the region not the chip it self. Other regions with them aren't bootloader locked.

OP would be better served if he/she included a Model Number. The specific properties are the same regardless. As everyone is aware price fluctuates depending on the seller.

Op isn't asking about the price though. Who knows where they are buying from.
Also the Korean models typically only have one model number. I think the same is true this year as well.
I figured the best person to answer their question is someone that probably knows they have a Korean model or someone with first hand experience with the Korean model.

The SM-9080 is the model number... If I bought and received something other than the device listed it would be of no charge according to provincial law. The 909B is also an option which is the EU enyox model or 908W Canadian Snap dragon. The 908W cannot be unlocked however the root/bootloader unlock specifies 0 in the title which I'm assuming is the suffix to 908 and possible.
Snapdragon and bootloader unlock would be the best of both worlds as performance is better and does not suffer from idle drain issues. The cost is also about 20% cheaper on sale.

I'm, just going to yolo one one see what happens. Worse case is I might need to update the CSC, the modems firmware should support the same frequencies to be "international/global" The s8+ I have was the int version and worked just fine.
Some rated specs do differ ever so slightly between the EU and NA model such as the post processing used for images and throughput for the NIC used onboard but is negligible.

Thanks, generally MFG do not deviate from designs much due to costs involved. If SN by design was bootloader locked one would expect variants to be the same. I think Korea had enyox models in the past too.
The site used was pda plaza (google it) which lists various models and if you are buying new is usually cheaper than vendors, amazon and other places. I saw a 512gb ultra as low as 1500 for the ugly green. Considering we get ****ty perks for buying a phone new it does not make sense to buy from samsung.com unless you want sky blue or something.
Also I'm unsure as to why you linked the store pages, retailers listing unlocked is carrier specific, not bootloader.

Oop, sorry all the 9080 is China, 908N is Korea, editing main post.

I linked the Samsung websites so you could compare official Samsung pricing. As stated there are many different retailers with various offers. I also asked for the model number knowing the SM-9080 isn't available in Korea which you've since updated. The S21 Ultra in Korea is the Exynos variant which only lasted 1 year, they've now reverted back to Snapdragon. Of the 3 SM-9080's available I would recommend the Hong Kong (CSC - TGY) but if call features are a priority the Taiwan variant (CSC - BRI) is the best option. Stay away from the China variant, it's a mess. Plus one should always ask a retailer which CSC they are offering, they don't always sell the same variant for the region they are based. You could purchase a China variant from a Taiwan retailer but you won't know it until it's in your hands. Yes, they will mislead and lie just to make a sale. Firmware for the 3 variants are interchangeable however it's usually not a good idea to swap, firmware is Home CSC specific and the Home CSC can't be altered plus that will affect updates as well. All 3 are bootloader unlocked however there aren't many Custom ROM's for Snapdragon devices. Goods luck!

The hardware is the same as HK, only the firmware differs and can be flashed. The recommendation makes zero sense. Call features are CSC based and I doubt much differs across the globe these days especially for major regions. That would be false that you cannot change the CSC, the whole aspect of root/unlocked bootloader is to modify system/firmware partitions or flashing with odin.

What do you mean it makes no sense? I've stated if you want call features buy your regions (CSC) device. I never said your CSC couldn't be changed, I've stated your Home CSC can't be changed. Have fun trying to figure everything out, we're done.

For those who also may care, I took the time to actually research things before speculating nonsense.
So the primary difference between the models is 5G support as apparently the 5Ghz bands are not supported in the firmware for the 9080. Given the 9080 can be bootloader unlocked it is a similar situation to the Galaxy S4 release across US/CA where you could buy the US model and flash a Canadian modem in order to gain support for carriers in CA. Likely the same can be provided for 5G support with a few hex edits to the existing modem or flashing one from another region considering the same hardware is used, however this would still need to be tested.

This would ultimately save people hundreds of $ along with providing the SN variant bootloader unlocked to various individuals and not end up being a slave to bloatware and poorly designed roms.
