Hello all.
Im sorry if this topic has already been adressed on forums.
I always found my stock N950F -ZTO significant slower than my XZ premium on LTE speeds on Vivo network (XZ always got double the speed on download/upload), until june that I decided to flash the TPA rom (I think it was the first Oreo to be released) and to my surprise the LTE speeds were on par (or even better) with the Sony.. humm, who cares I tought on the time. Last month Ive had to send the Note8 back to Samsung for a screen replacement, and It came back with the latest ZTO Brazilian Oreo version, and voilà, LTE speeds down to the hole.. hummm something is not right.
Why not try the latest XSG XEF? And my suspects were comfirmed - On both versions, a clean install, without fully changing to ZTO (XEF/XEF/ZTO), gives me the full LTE speeds, on the other hand, changing the CSC to Brazil, speed is reduced by half (I think carrier aggregation is disabled).
Why Samsung would do it ot its actual flagship (note 9 was note releasead here yet) ?
Has anyone experienced something like that?
Regards!
I currently use multi-line setting for my virtual number (Digits from Tmobile) and would like to continue using it for my future s10+. I'm tempted to go unlocked but I just don't know the difference.
I also heard about slow updates for unlocked? Is this true?
What's the advantage of getting one or the other?
Unlocked will have root + unlocked bootloader. It will run on Exynos. Tmos version will have Snapdragon and be completely locked down with no root.

I'm sure the US unlocked will be the Snapdragon just like the Note 9, exynos will be international. The unlocked version will see updates last after carrier updates according to Samsung this is because unlocked has to work on all carriers.
I tend to buy unlocked phones as they re-sell better and quicker
I always buy the US unlocked version (Snapdragon). No bloatware and I'm not tied to one carrier. I can change to the lowest cost month 2 month service any time I choose. No contracts.
Does this means that if I buy S10 locked to a carrier I will not be able to root my device? (assuming I buy the version in exynos)
Has anyone had success using unlocked Samsung devices with Xfinity Mobile (who does not currently support bring-your-own-android)?

Lol, oh there's bloarware, like two of everything...but yes, no added carrier bloat. That would just be unbearable.
As far as I'm aware, all the recent US variants of Samsung Galaxy phones, including the factory unlocked variants from Samsung, have traditionally come with locked bootloaders. It is likely this is true for the S10 as well.

The built in multi-line setting is normally available with T-Mobile branded phone, such as S8 and so on. Unlocked model didn't have multi-line support, but you can always download their digits app. If you don't want the app, then you would have to flash your S10 with T-Mobile firmware and get all the features and I do prefer to go with this route as you won't get T-Mobile's bloatware

Is there even word that we can even use Odin to flash another firmware on to the S10 like the S8 and 9?
T-Mobile is offering a hell of a better deal on the S10 than Samsung directly with both the monthly payments (if you choose that option) and a better S8 trade in amount at $390 versus $330. It might tempt me to go that route even though carrier bootups and firmware labeling annoys the hell out of me. If it's still possible to flash with Odin, buying from a carrier would be a no brainer. Flash off to the unlocked firmware if you want better rates, and then flash back when you want something on the firmware side.
If its the case like the Note 9 and the S9, then even though you buy the unlocked version, once you pop in the carrier sim the phone will reset to that carriers CSC profile including all the bloatware and apps etc... Change to another carrier and the phone will switch profiles accordingly.
Please correct me if im wrong.

Odin firmware flashing was possible on previous recent Galaxy phones, including the S9 and the Note 9, so I hope that is still the case with the S10.
If it is not, then honestly I would rather just buy the unlocked version based on principle alone: If I'm buying a phone at full price, then I would rather not buy one that is stuck with a particular carrier's firmware or branding. It's a Samsung phone, not a "TMobile" or "at&t" phone.

When I was preordering S10e, I was at two roads: T-Mobile variant or unlocked, but it didn't take me long to realize that unlocked would give me more flexibility.
When you flash unlocked unit, it is just a standard flash: using Odin pick a carrier firmware and flash. When you flash a carrier branded phone, in most cases
you would needed "factory binary" firmware because you would need to change CSC(unless your carrier phone was multi-CSC) to the one you need, than in the dial, type some commands to pull up CSC changing menu and after saving and restarting phone, then flash a firmware of your choice In other words it was a longer process. That I why unlocked phone would just be a regular flash and a fast one.
I can't guarantee that there will be a way to flash S10, but most likely it will be possible to do it. I even flashed Galaxy S3, S4 and so on.
I think couple of years ago Samsung made an unlocked firmware that would detect which sim card is inserted and tune the firmware to that sim, but to what extent, I don't know
Also unlocked phones mostly are approved for Samsung beta testing of new Android built(if you are into this)

The Snapdragon unlocked, U1, is only sim unlocked, not bootloader unlocked.

I'm wondering... regarding changing the CSC if flashing from a carrier-specific firmware to the unlocked firmware, is this the equivalent of needing to use a patched Odin that bypasses CSC match check? I've never actually done this process, but have been reading about it.

The last phones I flashed was my unlocked S8 and Sprint S8 Active.
So when I flashed my unlocked s8 to T-Mo firmware, I just used regular Odin because unlocked phones have multi-csc codes for many different carriers.
When I needed to flash back to unlocked XAA csc, then I had to use modified Odin and flashing completed successfully.
With Sprint S8 Active model, I had to jump through few hoops and it wasn't pleasant as at the time of my flashing, most people had other phones and no special "factory binary" firmware was freely available.
I don't recall exactly, but: I took Odin(possibly regular) flashed with special factory binary firmware which had the ability to change csc codes to the one I need, then it would restart my phone, than I think I used modified Odin to flash the final firmware of my choice. I wanted to convert Sprint model to T-Mobile
Hi,
Can an S10 model G973W (Canada) be converted in a way to use the international/unlocked updates? I love how my Note 9 can take an update from a huge variety of CSCs but my carrier purchased S10 didn't even get a June security update and is not scheduled for an update until at least July 2nd.
Unfortunately not without unlocking the bootloader, and to be honest, there really isnt a good CSC for the snapdragon S10, the US Retail is very behind on updates, i wouldn`t want a chinese CSC, so it only leaves the vietnamese (model G9370), which most of samsung apps do not work properly
Your best bet is custom roms, or just straight install GSIs
Wait...chinese csc leaves ,vietnamese? Hmmm

As far as i am aware there are only 3 retail CSCs that would work on the 973W, those listed in my post:
US Retail, Chinese retail and Vietnamese retail
- US Retail is updated less frequently than carrier models
- Chinese comes with a ridiculous amount of apps
- Vietnam doesn`t have spay working outside of asia
I dont know if i should`ve made it more clearer, the wording in my post makes sense for me
There are other snapdragon models (X, G9767U), but these are not compatible due to hardware differences with the 973W or do not have retail CSCs
Hey guys, hope everyone is well!
I've been doing alot of reading of various posts and sites and am getting myself quite confused! I was hoping some of you may be able to point me in the right direction!
I bought an unlocked new note 9 from ebay (I'm in the UK). I'm currently on three and dont think I ever really did a factory reset when I first got the phone.
The details are SM-N960U , Baseband N960USQS2CSGB , XAA/XAA/SPR
My three wifi calling is working which is good, however I am still stuck on August 2019 update. I thought I could perhaps flash this with a OXM firmware or even BTU to start getting updates again. It would be good to get security updates...!
Using Frija I can only seem to find USA firmwares though, and can't find any firmware online for UK sm-N960U (BTU/XEA/OXM). Just wanted advice on what you recommend? Should I just download the latest USA firmware from any of the carriers and flash that using ODIN? Frija doesnt seem to be able to even find any firmware with CSC XAA. I'm worried that if I install a new USA carrier firmware it'll lock the phone and I wouldnt want to lose the three voice calling either.
Any help/advice/pointers are much appreciated! Just couldn't find this particular situation on any of my searches!
The N960U is a North American only variant, with a Snapdragon SoC and non-unlockable bootloader, you won't be able to find any firmware for regions outside USA or Canada, neither will you be able to install custom ROMS.
I believe that the UK models are using the Samsung Exynos SoC.
But... You get the FM Radio on the chip, with the App NextRadio, and with a set of wired earbuds you can listen to OTA radio.
SPR was the carrier Sprint, now gobbled up by T-Mobile, (CSC; TMB)
My carrier Xfinity Mobile, CSC: CCT (Comcast) has WiFi Calling enabled, and has September update in Frija.
However, if you are getting WiFI calling on Three using the SPR firmware already on the phone, you might as well download the latest one, which is the Sept 20 update also.
FWIW, Flashing ROMS using Odin doesn't reset the SIM Lock.
I pre-ordered our phones (my wife received hers the day before the official launch, mine arrived the day after the closing date for claiming the pre-order bonus, luckily they honoured it due to overwhelming demand for the model that I ordered) and Xfinity unlocked them a month after we received mine.
I have flashed other official US ROMs before returning to the carrier's firmware and was still able to slip a Vodafone SIM in at Heathrow Airport and still enjoy glorious UK LTE during my vacation through England and Wales last April.
Hi all. I have the a few sm-g998b phones, rooted with magisk, and I am a bit confused about which CSC I should flash to the device (SAMKEY). I ordered the phones from Singapore and need them be more compatible with USA verizon and USA tmobile. Only using one sim per phone. Which CSC should I replace the current SIN csc with for each, and is there anything else I can do to make these phones play a bit nicer in the USA? I am currently having issues with no 5g, poor wifi calling, no updates, etc.
1. Avoid SamKEY. Do your own work.
2. Flash the HOME_CSC, or the CSC of the firmware of the carrier. HOME is usually a safer bet though.
You're going to have issues in the US until you flash the proper CSC. AFAIK, every S21U has all radios, but the CSC activates the correct one.
For the absolute safest, download the TMOB stock firm, and flash the HOME_CSC (as well as the BL, AP, etc), then put the Tmob SIM in after boot.

Tmobile or any US firmware can't be flashed on any Exynos Global device.

Why would you aquire the Exynos Global variant knowing your service provider isn't optimized for your firmware? Did you save money? If so I hope saved a lot otherwise it was a poor choice. Your best option is keeping the stock SIN Firmware, at least you'll get timely updates. You MIGHT get Wifi Calling and VoLTE enabled but forget about 5G and Carrier Aggregation.
Missed that you mentioned an Exynos variant. Yeah, you're ****ed. Exynos is not compatible with US bands, or at least aggregate banding.

Unfortunately, these phones are company. we needed root for some applications.
*don't use SAMKEY
This is a bit tricky because US is Snapdragon-based.
My best bet would be to factory reset (don't forget to backup) and flash a multi-csc Exynos ROM (OXM). This would detect the most compatible one for your US sims.
I would suggest getting the XSP for Singapore because that's the unbranded one.
Other than n71 5G band for US Cellular, I don't think you'll have much issues.

"This would detect the most compatible one for your US sims" Nope, that's incorrect, Exynos Global variants aren't able to detect the most compatible US Networks. It's apples and oranges, there is zero integration for US devices.

Thanks for correcting me. Least that's how it was for me using NZ sim on a G9980 SD variant.

The Exynos variants are Multi-CSC Devices, mainly for Europe, not for the US. The SM-G9980 isn't a Multi-CSC Device unlike some US Models, it's Dual-Sim. In Settings under Network Operators you can have the device select the "Best Network" but it isn't analyzing call features, it's only matching the network with the Active CSC (SIM Card).
Bro,
On the stock phone dialer key in
*#2263#
You will see the bands the 998b supports.
Now u need to check on the networks u plan to use in the US what bands are used. Not sure what u plan to do but these exynos phones should be able to roam into the US with voice n data services. Not blazing gigabits but one should be able to roam globally with these phones.
