AFAIK, out of all of the "U" models of the Note20 Ultra, only the T-Mobile version has eSIM capabilities. There's a couple of threads around here in Note20 Ultra land on the subject.... I'm not sure if flashing the T-Mobile US firmware will bring up the option on a U1 device.

This worked in the past, flashing TMB firmware using modded Odin.
However I have a new Note and have tried many times to flash TMB firmware but cannot get it to stick. I am stuck on XAA CSC.
There is another thread where people got it to work originally however I am wondering if Samsung did something to the bootloader to prevent the CSC change. I really want to get this to work , if not , I may return it, still have a little time left. Plastic film still on phone

Would this work?

Ok i'm sick of paying 1k for a Samsung exynos phone that's inferior to the SD855 and listening to the SD owners gloating they have a better phone on youtube etc.. I have even heard the Exynos S10 9820 is slower than the S9 SD 845 FFS!
I live in Ireland and we get the Exynos version. So if i went on Samsung USA website and preorder an UNLOCKED Note 10+ by Paypal ( they give that option). Have it sent to my cousins house in the USA ( I'll be visiting in the next couple of months). Put her sim card inside and get her to make that 10 minute call. Bring back to Ireland and good to go?

I don't see why not... It's an unlocked phone. Just make sure the bands match up with your carrier

Thanks for the reply. Yeah i have found ( with the S10 phones anyway) that the unlocked versions directly from Samsung USA have the most bands and the ones i need. The carrier branded ATAT and T MOBILE phones have less bands.

Lol the note doesnt even use the 9820 its running the new 9825 exynos anyway so your complaint makes no sense.
Also hope you realize the the US snapdragons are all BL locked and the exynos is not.

I know it uses the 9825 but it's still not up to the 855 and it uses the crap Mali GPU so my " complaint " is a valid one. BL locked? You mean regarding rooting? I have no interest in rooting to be honest.
But do they notice the differences in a real world testing instead of how many it can perform floating point calculus which is totally irrelevant?
If social media subjective opinions matter to you, do the Exynos version also tend to be more battery friendly which is quite more important than the few seconds that it will take to unzip a archive.
(Yes I'm a bit sarcastic.)

On the S10+ SD the battery will still have 20% when the exynos version runs out, according to Supersaf on youtube. Anyway the phone will work out cheaper for me from the USA.
Sort of seems like you already know what you want to do. Yeah, long as the bands match up with your carrier, you're good.

I think you have that a little bit backwards because the Snapdragon version has better battery life than the Exynos. I have the S10+ Snapdragon version just check the forms over there.

People still root phones? Man it's like 2011 all over again. Android is pretty mature, I personally haven't had the need for root in like 4 years lol.
The answer to the thread start is quite simply, YES. Simple ask and answer.

1) Why would you need to make 10 min call in the USA?
2) The unlocked model has mostly USA CSC codes in the firmware. Which carrier do you use in Ireland?

1. Phones from different regions are usually region locked. By using a sim from the country a phone is bought and making a call for approx 10 mins usually unlocks it.
2. Vodafone Ireland.

Hmm, could it be that the "region lock" is mainly for EU countries, as I have not seen this on US unlocked phone, then just were unlocked
The US unlocked models have the following CSC codes in the firmware: ATT, SPR, TMB, TMK, USC, VZW, XAA and a few others. I wounder if the phone's firmware doesn't have sim card's CSC in it, how will the phone properly configure the carrier's features/settings.

All the better if no region lock..
Vodafone Irelands CSC is VDI. However my S10+ is on BTU ( unlocked UK/IRL). The phone works perfectly on BTU ( even VoLTE/VoWiFi works). I had a Note 9 from Asia somewhere and it worked perfectly too (not sure about VoLTE because my network didn't support it at the time...)
I know i may have problems with wifi calling on the USA model but i can live without it. What would the USA unlocked CSC be anyone know?

It is XAA, but once you put in the sim card that is included in the firmware, then it will refresh sim data and activate CSC from the sim. So in my case, I use TMB(T-Mobile) and from XAA, the phone switches to TMB after I put in the sim
Interestingly my carriers network isn't listed in "available CSC codes" on the UK/IRL unlocked model on Phone Info. My girlfriend who is on the same network as me bought a phone through the carrier and it's on the unlocked BTU csc.

I totally understand that. I also realize that the improvements are not nearly as necessary as they used to be when Android was a gross mess and needed Devs to really make it run. It's a mature phone OS and most of the development going on is really minor stuff. I do appreciate that people are still interested in flashing ROM's and things like that, the community stays alive, although not nearly as robust as it used to be.

Sorry I'm certainly wrong indeed because I only compared with what it is said about the Note 9.
I'm still unsure about if it's really relevant to compare the S with the Notes series. ?

Korean Variant SM-N986N CSC KOO

I know there are discussions on changing CSC already, but I have the opportunity to get an Unlocked Note 20 Ultra 5G from Korea.
It's coming directly from Samsung, and not SK or any of the other carriers, so I am assuming the CSC will be KOO.
Will the CSC being KOO allow for an easier time to flashing it with an RWC (Rogers Canada) firmware? or is it still a pain in the butt to change?
I know the previous methods are not working on the new devices. Just want to make sure before I tell the person to go ahead and bring it over.
Also will 5G in the Korean variant work in Canada? trying to catch up with the 5g tech, Rogers just rolled out a whole bunch of 5G areas
Thanks ; >

both of these topics have been discussed at length in the last few weeks here.
we are not yet able to cross flash firmware (although i haven't seen anyone try it with the modified version of odin) but flashing between canadian and korean firmware is a real stretch at best.
5g 100% will not work on rogers totally different bands
gota use that search button next time dude, you would have found alot of information on this likely!

thanks figured out 5g bands are different and i dont really need it.
tried searching, but nothing came up for specifically KOO CSC code, as i read in the s20 forums that KOO will make things easier to switch over..
I read people trying to switch from SKT csc, but not KOO... hence why I asked since it wont be carrier locked.
so i did search but found nothing related to the device i will be getting. Maybe my search key words were not correct

I haven't seen anything on KOO either honestly but flashing rogers firmware in a Korean device I think isnt possible at the moment. Technically same hardware but the model number being different odin wont allow it.
You would be a brave man using modified odin to flash anything on $2000 phone right now lol

yep.. haha wont be doing that...
probably just use it as it for now, since there wont be any bloatware from SK or any other carrier.. and hope samkey figures something out.. Samsung Pay i will kinda miss, and if some apps wont work , but the ones i use seem to be ok..
LTE+ is just fine for me, I woulda turned of 5G anyway if I purchased from Rogers to save battery.
Although woulda been neat to see how fast it is, since Rogers just rolled out more 5G coverage in my area
It won't hurt you to stick to KOO. In comaprison to other Korean - say SK - CSCs it has a lot less bloat. Also, most the bloat can be removed.
Don't really see much of an advantage in a very risky firmware switch. (prolly won't work anyways coz of different radios).

What is the difference between US version N986U and N986U1?

Anyone know what the difference between the two? Or if there is a differenc e at all. I am on ATT network in US.
Carrier unlocked U and factory unlocked U1
U is for the carrier variants in the US. U1 is for the factory unlocked version which you buy directly through Samsung. Even though unlocked, the U model will have a carrier logo when booting up. If you want true unlock, go for U1.
Can I flash N986u1 firmware to my galaxy n986u ? Will i loose esim feature? I want to do because I am not getting 5G and also ota updates
If you flash a note 20 (or other Samsung phones with Knox for that matter), you'll permanently blow an efuse which removes some phone features like Android Pay. I didn't think that the esim feature was one of those features but I'm not totally sure on that.
Guys, i need a fully support arabic language
For
SM-N986U​
should i change to U1?
its already unlocked phone with Verizon
so any sim is working
but the 5G is not working
AND a full arabic is not there.
if i changed to U1 will i get a full arabic lanaguage? ?

As for 5G with Verizon, check the coverage map in great detail! Unfortunately, you may find that it just doesn't currently exist where you're testing. I've had Verizon Reps (at multiple stores) argue with me that 5G coverage did exist in areas and eventually find/admit they were wrong.
After doing my own research on Verizon coverage, I've found that their 4G LTE coverage is very good, but their 5G coverage is pretty much only in (5G mmWave) and around (5G UW) big cities and even spotty in those locations. When Verizon claims they have "Nation Wide 5G", think of coverage which looks kinda like a chain link fence. Verizon is spending much money to fix this lately, so hopefully it will improve quickly.
For the time being, I've abandoned Verizon for T-Mobile because of its indisputably superior 5G coverage in the US.
N986U vs N986U1: As for switching to a U1, I'd say don't. I have an N986U and my wife has an N986U1 and I get Android updates much more quickly on my U and she does with her U1. It's weird but true.

Question S22 Ultra esim enable TGY csc

Hello all, new here! Never rooted a device, I'm very technical and confident but would like to ask the question as to why I'm looking to root or change CSC.
Currently my S22 ultra 512 is a Dual sim Hong Kong purchased device. TGY is the current CSC, basically I'd like to use the esim option and phones sold in Asia specifically China, Hong Kong & Macau at least I'm told have this disabled. My note20 ultra dual sim is the same. By changing csc/firmware can I enable this feature that other s22s have? Basically is there another s22 with identical hardware dual SIM and all that I can put on the phone that will enable this feature? I'd like call recordeding if possible as a phone feature rather app but it's not important. I'll attach screen shots of what versions I currently have. Sorry if I'm asking the wrong questions I'm technical but new to android rooting.. Willing to PayPal or donate to anyone who can assist me through the process. SM-S9080 TGY I know the Taiwan sold device is basically the same hardware but have not received a clear answer if esim is enabled, thinking no but figured I'd mention it. I'd also like to do the same to my Note20 Ultra. Thanks in advance

Hi Guys, someone can confirm if CSC TGY have esim activated on S22 ultra SM-S9080? o wich carrier could have it?
I'm having exactly the same issue... just tried out the HK and CN variant. Both don't an eSIM support.
However, I've also read somewhere that Samsung has "dropped" the eSim support in on of the recent Firmware versions, because the had too much trouble with that.
So the quesetion is: Is this a regional issue (e.g. TGY, etc.) or is is a "Version" issue (e.g. an earlier version still might have it)
Best!

hi i have a s9080 hk model and tried flashing the s908e/ds firmware through odin buy kept getting failed partition error
i want to share my experience with my note9, it was the N variant - South Korea, i had network issues in which case i had to root my phone and install a custom rom which had csc of my country and i worked great.
if you could do with a rooted phone follow this:
1. check if your phone is listed as rootable.
2. check if your phone has a custom rom:
if YES you could see or ask for what you need ( in the Rom's forum or the developer).
if NO wait and keep researching.
dont flash another region firmware even if its the "same phone" you might break the phone.
Okay, quick info: I've flashed all three regions (China, Hong Kong, Taiwan) on the SM-S9080 (current firmware versions june to Sep) and none of them have eSIM support.
This is really annoying - especially when all the offical samsung websites praise that the phone supports esim.
I'm personally pretty pissed off and the key reason is that I know that other users of the same phone in other regions of the world can use it and I'm not able to do this, because the programmers just want to make their lives easy and "silently" drop this feature from the firmware.
Something similar happened about 15 years back with a Sony device and since then I've never ever bought anything from Sony again (neither phone nor anything else). So the same is probably going to happen with Samsung.

When you flash a different CSC, I read that since basically the firmware reads your sim, grabs the CSC from that, that if you leave it out, on the boot up screen before you start the setup, you can hold Volume down, I believe or some button combo to skip through set up so you don't need a SIM to complete it.. then you have the actual firmwares original CSC and not the one that was read from your SIM card.. Cuz if not no matter what firm u are you flashing, if your SIM card is in there and you run set up it's going to go by that. The firms are supposedly all the same but what's changes is the CSC each time.. now overseas, United States, snapdragon vs Exyno it's a different story. They do have different firmware's...
But I do know that the phones are basically all universally the same all the same hardware but it's the firmware the software that does all the matter of difference... Including the bootloader for instance. We all have the same hardware but I can't unlock mine it's software there that can do it.. if I find the site up forward it for you.. have you gone into the service mode after enabling it? There's a bunch of crap you can do in there that has to do with antennas and SIM cards and ESIM stuff you might just need to enable something.

What I've (think to have) learned so far:
There are two different hardware combinations: (a) the snapdragon variant and (b) the Exynos combination. For each combination, there are differernt firmwares available
Each firmware (e.g. SN-S9080) is a special combination of modem-settings, software configuration, etc. that is geared to optimize the phone performance and battery consumption
For each firmware, you have then certain CSC variants, wihch then further add which apps are available, etc. (for example in the Taiwan variant, Google is available, while in the China Mainlaind variant it is not)
During the first-time installation process, you can choose the language of the phone (and maybe also the CSC), but you can't change the firmware
Therefore, my problem is this: I've tried all the CSCs which are available for m firmware (SN-S9080) but none has eSIM support. Now I want to flash a differetn firmware (e.g the SM-S908E firnware), but Odin currently doesn't let me flash this onto my phone.
Does anyone have a guidline of how to flash a SN90E firmware onto a phone which currently runs a SN-S9080 firmware?
Best!

There are two different hardware combinations: (a) the snapdragon variant and (b) the Exynos combination. For each combination, there are differernt firmwares available
Each firmware (e.g. SN-S9080) is a special combination of modem-settings, software configuration, etc. that is geared to optimize the phone performance and battery consumption
For each firmware, you have then certain CSC variants, wihch then further add which apps are available, etc. (for example in the Taiwan variant, Google is available, while in the China Mainlaind variant it is not)
During the first-time installation process, you can choose the language of the phone (and maybe also the CSC), but you can't change the firmware
Therefore, my problem is this: I've tried all the CSCs which are available for m firmware (SN-S9080) but none has eSIM support. Now I want to flash a differetn firmware (e.g the SM-S908E firnware), but Odin currently doesn't let me flash this onto my phone.
Does anyone have a guidline of how to flash a SN90E firmware onto a phone which currently runs a SN-S9080 firmware?
Best!

i think the chinese s9080 is locked down only because you cant flash other firmware like other models most secret codes like to change bands dont work and this model took agesto get one ui 5.0 update
Well, I can flash different CSC variants, e.g. the Taiwan or the HK variant (and these are not multi-CSC firmwares, but seperate files).
However, does anyone have an idea of how to flash e.g. the S908E firmware onto a phone that is currently running S9080?
I was able to flash all files of the S9080 variant (including BL - the boot loader), so that means that the phone is *not* locked, right?
I've tried to click the repartitioning option (because the S908E is bigger than the S9080), but that also didn't help.
Do I maybe really need need to "root" the phone first for flashing another firmware? This doesn't sound logicall, so I tried to avoid rooting so far ...
Any ideas or a link to a "how to" is warmly welcome ...

When you flash a different CSC, I read that since basically the firmware reads your sim, grabs the CSC from that, that if you leave it out, on the boot up screen before you start the setup, you can hold Volume down, I believe or some button combo to skip through set up so you don't need a SIM to complete it.. then you have the actual firmwares original CSC and not the one that was read from your SIM card.. Cuz if not no matter what firm u are you flashing, if your SIM card is in there and you run set up it's going to go by that. The firms are supposedly all the same but what's changes is the CSC each time.. now overseas, United States, snapdragon vs Exyno it's a different story. They do have different firmware's...
But I do know that the phones are basically all universally the same all the same hardware but it's the firmware the software that does all the matter of difference... Including the bootloader for instance. We all have the same hardware but I can't unlock mine it's software there that can do it.. if I find the site up forward it for you.. have you gone into the service mode after enabling it? There's a bunch of crap you can do in there that has to do with antennas and SIM cards and ESIM stuff you might just need to enable something.

with an without SIM card didn't make a dfference. The firmware files for 9080 are all single CSCs anyway.
So after more than five weeks of trying around, I finally have to say that it seems impossible to enable eSIM on a 9080 (i.e. the version bought in China).
I've tried so many things by now (the VN Rom, the Dr Ketan Rom, switching CSC to Hong Kong or Taiwan, etc.).
So my conclusion is this: You have two options
a) Don't buy a Samsung Galaxy phone at all
b) If you really want to by a Samsung, then buy on from a region where there are the least restrictions on your firmware in the first place.
Everything afterwards turns into frustration.

They are essentially the same device. I Odin back and forth between the U and U1 roms. Whichever comes in with the latest update. I prefer the U1 as theres no carrier crapware. I have never been able to ascertain if there's any advantage being on the U, or if it gives any data or signal priorities with my carrier.

The US 908U1 models generally get updates after the U models. At least on Verizon they do. I have the S908U and my daughter has the U1 version of the S22 (we're both on Verizon). I normally get updates about a week or two before she does.
But U series are carrier specific models and U1 are unlocked versions....ur daughter might be getting updates earlier as she got an unlocked variant which gets updates first as compared to U models as service providers alter the software update before rolling them out i guess
Can anyone help me out why my network selction option in greyed out on automatic....
Can't change it and my network keeps fluctuating between 4G and 5G and its killing my phone's battery way faster now

Nope. She's gets hers about a week or two after me. For the past few years, Verizon has been pushing updates quicker.
As for locked. My phone is unlocked too. Verizon unlocks its branded devices after 60 days.
