Mine is LG G7+ G710EAW from HongKong. In the box it has a paper written about region lock that takes 30 minute local call to unlock. I don't live in HongKong, so I assumed the shop I bought did all this for me.
I want to flash a new firmware to another region and perhaps re-flash back to the original one. Will region lock come back (or even worse, the new firmware has it too)?
I tried it myself today. The answer is no. It will not come back.
Did you experience the region lock limitation or just saw a notice about it?

My G7+ was region locked to China, Hongkong, and Macau area. It had been unlocked properly by calling using a regional sim card, Now I don't live in the country of purchase anymore (Hongkong).
I was afraid if there should be something that would trigger the region lock again. However, after hard resetting and flashing another firmware, seems that region lock once unlocked properly will be unlocked forever regardless of whatever you do with the phone.

When cross region, just use the same model number (mine is G710EAW ), whichever region is OK. Hongkong firmware on my G7+ does not support VoLTE and LTE-U in my country so I flash Indonesia firmware to enable them.
You can find all G7/G7+ firmwares on all variants on the internet easily, just use LGUP, .dll file for your device, and USB driver to flash the firmware you want.
Thx for your information.
Even if there was a chance that it is not permanently region-unlocked, you could always just order the unlock code from one of the many online unlocking services...they basically just get the unlock code for you from the manufacturer. Then you could just keep the code handy, in case you ever needed it...
I paid like $14.00 for the unlock code for my black UK/EU Region LG G7 (G710EM) when the U.K. seller that I bought it from mistakenly shipped it to me in the U.S. without first making the local region 30-minute phone call...but it was cool being the first one to actually unseal the box, and it took less than a day for the online unlocking service to send me the code after I ordered it.
I just bought another one from the same UK seller (in platinum grey), and this time I actually requested that they send it to me still sealed (and still region locked)...I will just order the unlock code like the last time. All good!
Good luck, in any case!
Cheers,

Similar to the thread, I'm using LM-G710N which is the korean variant. I guess the store did unlock for me so if I flash other region or international fw, will I be able to take advantage of these variants' dual sim ? Since my dad has a korean samsung s8 single sim which now converted to use it with dual sim.

were did you get the dll for the g7 plus LMG710EAW I cant find them, i just found the g7 model but not the plus dll. also do I need to unlock the region first in order to flash another firmware from other country??
I own the g710n (korean version) but I'd like to install the EAW version for the European market; does anyone know if it possible?

I'm trying to get the USA version of Samung Pay working on my SM-G9600 (International Unlocked Snapdragon S9). Unfortunately, my active CSC is currently set to TTT (Trinidad/Tobago... not sure how, I flashed a CHO firmware, haha), so even when I have my Samsung Account and AT&T SIM card inserted, opening S-Pay just gives me an error, "Unable to connect to Samsung Pay temporarily. Try again later."
To remedy this, I think my best option would be to flash a new CSC from a different region? However, I don't really understand how Samsung's CSC system works; I've tried researching it, but I haven't found anywhere that really explains in detail what CSC actually does, single-CSC vs multi-CSC, etc... Can anyone give me a summary of all the major parts? Or at least point me towards a good resource to learn about it?
However, I have more practical, direct questions:
Could I flash my G9600 with just the CSC (or better, HOME_CSC) of a USA Snapdragon variant, like the U1? Or would that break things, since it's a different model number? Would that be likely to get me a working Samsung Pay?
I guess I should flash the CSC (or better, HOME_CSC) of a different region that also carries the G9600? Of the regions that carry the G9600 (China/Latin America), I believe the only countries that support Samsung Pay are Brazil, Mexico, and Puerto Rico (and Hong Kong, but only with Hong Kong banks? I think.) If using a CSC from the US is a bad idea, which of these would be best? I'm guessing Puerto Rico, since it's most closely related to the USA, but the only PCT firmware on Updato currently has the v1 bootloader, but I'm already on the v2 bootloader (2ARE6), so I don't think I can use it.
I would guess that the next best option would be Mexico, since it's pretty close to the USA, and I see a firmware with the v2 bootloader for it on Updato. However, I'm not familiar with that region code. Is MXO a specific carrier in Mexico? Or is it the carrier unlocked firmware, like U1 is in the US?
MXO is unbranded bro and working samsung pay.
I wanted flash a specific carrier csc but I couldn't set TCE always appers CHC.

Yes! Dual SIM is not affected by which SM-G9600 firmware you flash. The thing to be wary about would be if you tried to flash a different model's firmware to it (e.g: G960U), since there is no Dual SIM among the U models. Although if I had to guess, the Dual SIM settings would probably still work fine (assuming the U firmware didn't brick it otherwise).
Have you found a fix for this problem, are you able to use samsung pay here in US?
Did you change the csc only or flash the whole frameware?
Thank you in advance.
I'm also wondering about flashing just the CSC on a dual SIM device. I have a Note 9 dual SIM that will not get Volte, so I was thinking about flashing the U1 CSC to see if it would fix it. Does anyone have any advice?
You guys are so good at this compared to me. I felt like a noob ?.
I posted a question a few days back but not getting a meaningful answer. The goal is to do minimal changes but get Samsung Pay working.

I live in Canada and have a N975W and want to flash the star wars U1 firmware, but before I do I wanna know what happens when you put a Canadian Carrier sim in?!? Will the U1 CSC have Canadian Carrier info preset? Will I have to manually modify to get things like MMS to work? Or does the U1 firmware have Canadian stuff preloaded that gets triggered with the Sim card?
Thanks
Nobody?
Exynos

The American CSC does not contain information for Canadian carriers. After you flash the American U1 firmware, flash the Canadian CSC. There is only one CSC for Canada, and it contains information for all the Canadian carriers (Bell, Rogers, Telus, etc.). After flashing the Canadian CSC, when you insert a SIM from a Canadian carrier it applies the settings for your carrier's VoLTE, wi-fi calling, APN, etc.
If you flash Canadian CSC after flashing full U1 firmware will it not effect the U1 firmware? The CSC file is so large I'm wondering how it will effect the U1 firmware. Anyone do this yet? Do I need to use modified Odin?
Have you done this? Does flashing a different CSC effect the firmware?
---------- Post added at 11:58 AM ---------- Previous post was at 11:57 AM ----------
I would appreciate any input from someone who has tried this please. I really want to flash the star wars Android 10 for U1 on my 975W but am afraid that CSC will be different and not sure If flashing CSC from a different firmware will work as the file is so big.
if it doesnt work, you just flash back to stock firmware and csc.
just make sure its for the same processor.
OK, so, I flashed first Star Wars Android 9 version of U1 firmware to test and it works perfectly. Booted up with Canadian carrier sim and it loaded all APN settings. Everything works perfectly.
Flashed Android 10 version of Star Wars U1 firmware and its all good.
So you can load U1 firmware on N975W unlocked version. Same hardware and works in both countries. Do not even need Canadian CSC.
Do not load the HOME CSC file. It will wipe everything but its worth it. Firmware is solid and beautiful.
By flashing unlocked firmware, did you get rid of any carrier bloatware?
Can I ask you guys an info? I own N975u1, on first boot It haven't Greek language and I choose it later at setting. Does N975w on first boot has Greek language? So I install N975w firmware to solve my problem?(some settings remains in English).
975W is Canadian model and i have it on my note 10+ with carrier esk or eastlink if you wish to know what carrier esk stands for. If you are trying to get your phone to show Greek language I do not believe the 975w firmware would be a good choice. It lets you select which country you are from when you start up a freshly formatted phone but I have never selected any language other than Canada which is English. Just thought I would let you know that my model is also a Snapdragon chipset and I don't know if you can Flash another firmware unless you unlock Bootloader and I do not know if that is possible currently on a Snapdragon chipset Note 10.

The only phones with an unlockable bootloader are the N9750 (chineese variant) and Exynos models.
Can you please be more specific with what you are looking for within regards to firmware. Other then the information/answers posted in the first page of this thread I saw this thread, but depending on what your looking for specifically the post may not be of any help.
Also be aware that if you want to retain full compatibility with Virgin then you shouldn't go messing around with the firmware. Flashing other firmware (especially for US models) can result in things not working the way they would normally.

Only firmware for OEM UNLOCK switch in developer menu is exynos models. I found other sites on the net stating SM-N975W Snapdragon can be bootloader unlocked but i tried them all and none worked. DO NOT flash exynos firmware on Snapdragon model as you may ruin your phone or void warranty. Luckily mine still shows official and knox counter didn't get tripped. Sorry, wish I had better news 4 ya.

You need european version, so G710EM (64GB) or G710EAW (128GB)
i get that i need the european version but the american handsets will work too and i've been told to avoid the Tmobile version at all costs.
i just needed to now which is the best variant from the american/canadian ones!
cheers
Canadian AWM version. Support more lte band (for UK and Europe) then USA unlocked ULM
thanks siley
only g710EM
now im confused???
Get the 710em that's what I got when I brought mine worked fine
I told him EM or EAW is best for Europe, but he want model from America so Canadian AWM is better.

I think is a crossflashed device. Mine is EM too, but came with open EU rom and it is a TIM device (italian carrier). Amazon things...
U can flash any firmw u want with lg_up 14-15, but with no ota support due to restrictions. U can always search ur region with ur imei in internet after a simple search on google, but if the device is from carrier... I recommend u a clean open eu kdz over any carrier firmware.
I recently obtained a Samsung S20+ SM-G9860. However, I am in the US and am intending to flash the AT&T firmware for the SM-G986U. When I try to do this, I get a secure check fail on the PIT file due to the differing model. Is there a way to circumvent this? The two models have identical hardware from what I can see.
Is it possible to do this, and what is the process for doing this if it is indeed possible?
You cannot flash a rom built for a snapdragon chipset on a phone with a exynos chipset

The hardware isn't identical, SM-G986U is a Single SIM Device, your's is a Dual SIM.. TGY is the CSC in your device and even if you could flash SM-G986U Firmware the CSC would not change, it will still be TGY. If you're looking to get full AT&T call functionality on your device it's not possible as the CSC doesn't support AT&T compatibility. Firmware is CSC specific as well.

I bought my phone online.. When I start up my phone it says Verizon, but its unlocked though because I can use any country physical simcard. Like right now im using my local simcard in Malaysia. I live in Malaysia and the reason I want to flash rom my SM-G986U device to Hong Kong firmware is so that I can use any eSim network in my country for my other network phone number.... If its a software for eSim that I can get for firmware that will be very helpful. Because the main local Malaysian samsung s20+ 5G firmware model is base on Exynos 990 which I doubt will fit for my US phone model..
I don't think you can flash SM-9860 Firmware onto your device but even if you could you still won't have eSim capability. Mix and matching firmware typically has more success on Exynos International Variants since they are Multi-CSC Enabled Devices. So if you have a British CSC (VOD) you may have success flashing German Firmware (VD2) since both CSC's are already stored in the device however even then some call features may not work. Snapdragon Devices don't have Multi-CSC's and as mentioned previously the Firmware is CSC Specific, they're made for one another. IF you had an Unlocked Bootloader, which you don't, there may be a method to modify the CSC once you root the device.. I did follow a thread a couple of years back where a gal had some success modifying her CSC on a Snapdragon Device but I believe that was a Galaxy S8. Also, I'm still curious if the word "eSim" actually appears in the SIM Management Screen on your device.

Damn.. that is some nice insights..

I just have to wait for the network shop to open up to change my current esim card to physical simcard.. its been 2 months plus of this coronavirus lockdown and our network providers cant do much about it too..

Not possible, the only options are flashing the SM-G9860 China or Hong Kong FW.
Hello,
Newbie question here coming from someone with Exynos model SM-G988B/DS (purchased while visiting Singapore):
Can I make this phone fully compatible with North American carriers? I'd like to use Wi-Fi Calling and VoLTE - but my Canadian carrier says that this phone is not eligible for these services because it's not a North American variant. A USSD code provided by my carrier was not successful (it said "invalid MMI code").
Even though I'm not entirely comfortable flashing different firmware onto Samsung phones - in this case I am desperate to do it (if it can be done to achieve my purpose at all...)
Now I'm kicking myself... wishing I knew that these calling features might not work back in Canada.
Thank you for your advice.
this is odd.. my phone is purchased in Malaysia, the country north of Singapore, and we have different CSC codes.
Wi-fi calling and VoLTE is working fine when i am in Singapore using a Singaporean SIM Card and when i back home in Malaysia using my Malaysian SIM Card. (But this is on the Samsung Note 8, have not gone to Singapore since i got my S20+ shortly before Malaysia shut down the borders due to the Covid-19 outbreak)

Hello,
Newbie question here coming from someone with Exynos model SM-G988B/DS (purchased while visiting Singapore):
Can I make this phone fully compatible with North American carriers? I'd like to use Wi-Fi Calling and VoLTE - but my Canadian carrier says that this phone is not eligible for these services because it's not a North American variant. A USSD code provided by my carrier was not successful (it said "invalid MMI code").
Even though I'm not entirely comfortable flashing different firmware onto Samsung phones - in this case I am desperate to do it (if it can be done to achieve my purpose at all...)
Now I'm kicking myself... wishing I knew that these calling features might not work back in Canada.
Thank you for your advice.

Short answer = you can't. You will need to change the "region key" (csc) by using samkey. If you flash the firmware belonging to different region with different csc code, you will not get any ota update at all. Therefore you must flash the firmware of, say, Canadian region, as well as changing the CSC to same set that Canada uses.
However: do *take note*, do *not* flash snapdragon firmware to exynos set vice versa.

Yours works because those countries are still within the same region.

You're saying it cannot be done but then are telling me that it can be done using samkey. So which is it? Can I not flash North American firmware with the appropriate CSC?

This is obvious - I would never do such a thing.
As its an exynos device it won't play well with usa networks and you cannot flash snapdragon firmware obviously. If you were in Europe this would have been easily done by changing the csc to say UK BTU via samkey and flashing the BTU firmware etc. Usa is a more complicated given the bands are different over there. Also you probably won't get carrier aggregation and volte / WiFi calling is a lottery! Plus usa networks aren't as chilled out as the rest of the world and have hissy fits if you don't use their branded devices. Charge way more than most other countries too! ?

Not exactly. I'm in Singapore, using Taiwan set, with HK firmware & csc. It's 3 different regions
i'm saying it cannot be done by just flashing firmware like your original question
You *must* do both: update firmware *and* change csc. Now Samsung has locked the csc changing. You can no longer change csc by just flashing firmware of different region. It won't work. Change csc, then flash the firmware.

It is different region as the csc is different.
In your case it is complicated. You can try to flash in your local csc file via odin. Just the csc file nothing else. See if it will work.
The firmware for exynos and snapdragon variants is very different.

He cannot and must not flash sd firmware into exynos phone. It'll brick the phone. Taiwan and hk is sd variant.
Ok - thank you for your responses so far.
So what is the absolute best thing that could be done in order to be *the most* compatible with North American carriers? What CSC should I be aiming for and which firmware to be exact? Could someone please link me to the appropriate files? I'll do my research once I have an idea of what to start with. (If it won't work - I obviously won't bother with it... but I think I should do some more research before I completely give up...)

Yes, I advised him same thing in my earlier post above. sd & exynos rom is not interchangeable.

you're in tough luck. USA bands are different from most of the world (https://sea.pcmag.com/smartphones/3...-americas-first-unlocked-all-carrier-5g-phone). To top it off, your set is exynos, and even if you can get firmware that works for USA set, it is most likely will be in snapdragon.
Btw, exynos version will never support mmwave in USA carriers, simply because exynos version does not have mmwave antenna.
I would suggest you sell that exynos set / exchange it to snapdragon set. With snapdragon, you have more luck finding compatible firmware.
Well... I cannot particularly exchange this device now that I'm in Canada and I've had it for over a month. And no one here would want to buy it since it's not local to the continent. I'm stuck with it here now.
I'll just use it for a year and then get some other new phone next year that's local to my region. There's a few other things I do not like about this latest Galaxy anyway... and I cannot see myself using it for longer than a year. What a pity though - I used to be such a die hard Samsung fan until this latest flagship. They screwed up so many things, namely - the battery life and camera quality.

That's precisely why I do not want to use local version here, which is exynos, the one you brought there.. snapdragon version is *miles ahead* and really is the flagship quality. I don't have issue with camera, the battery is insanely efficient (I have 2 WhatsApp, 2 telegram, email real-time-push, wechat, line, fb, etc) and I only drain 4% per 8 hours at night with all notifications still coming in
Yes, that's the snapdragon version, the real s20 flagship.
Try switching off 120hz. I'm happy with my 60Hz. Battery is pretty good, i usually unplig my charger at 630am.. It'll last me to 10pm with about 30% charge left.
This includes occasional messaging on telegram and whatsapp, some email checking and Facebook browsing. Working hours I'll be on office wifi. Lunch hour and after work 530pm to 630pm is my pokemon go hour which is the only time my wife let's me play games.
My phone is s20+ 4G variant, usually on 4G+, dual sim and 1 micro sd card (one of the sim is the esim). My display is at wqhd+ at 60Hz.
So far im happy with the battery life.
Just this morning, taking advantage of my wifes absence, did some gaming, namely war machines, the tank fps game and pokemon go.. From 630am to 1130am, Facebook and tiktok when I'm preparing and eating my breakfast. my phone is left with 60% charge.
Hello,
I would buy Snapdragon / Hong Kong version because I hate Exynos problems, but I'm a bit confused about CSC.
I've read the topic, and I understood that I can't flash Exynos (European) firmware on the Snapdragon / Hong Kong version.
Some people bought Hong Kong version and works very well in my country frequencies, but I would use Samsung Pay.
What will happen if I change CSC/flash to any european CSC? It would work or not?
Thank you a lot.

Samsung pay might work if the card supports samsung pay. But no way to know for sure until someone test it themselves.

Hey man, can you make a link a guide on how to change the CSC and Flash the firmware?
I have an s20 Ultra Exynos from Indonesia, and want to change the to Korean CSC and flash the firmware.

Wait what? Exynos definitely has MMwave antennae! If it doesn't that's news to me. Where did you see information that states that?

On Exynos & mmwave: https://www.bitfeed.co/2020/03/15/s...s-completely-disassembled-no-antennas-mmwave/ and https://eu.community.samsung.com/t5...-5G-supported-5G-networks/td-p/1577262/page/2
btw, you cannot flash Korean firmware to exynos. Korean S20 are all now using snapdragon
How do i unlock my Sim Network on Galaxy A71 5G T-Mobile carrier?
Please guys, how do i unlock my local sim network here in Nigeria?
I bought a second hand used Samsung Galaxy A71 5g from a vendor here. My local network won't work on the phone, telling me it's locked. The phone runs on a Snapdragon chip.
I'm really desperate about unlocking the network, how to i go about this?

What are you on about ? Short answer = Yes you can! I've been on Germany CSC (Im UK based) I've been on Abu Dhabi region and i was getting my OTA updates with no issues i think you were confused with a root as that breaks your phone.
