Hey 5G Pioneers,
I am wondering can I flash the sm-g 977b firmware onto the sm-g 977n device through the Odin? Did someone make it?
Since these two models are all using the same Exynos 9820 chips
And from my previous experience of using my galaxy s8, Samsung actually enabled me to flash the firmware in different regions only if the devices were using the same chip version.
I am currently in Australia. The Korean version of 977N is much cheaper, and it seems that is the only network unlock version that I could buy from the market.
Not sure where are you in Australia but I bought mine from a Telstra Sales Rep (based in CBD, Melbourne) where he got a discount code and gave its to me for AUD 1400 for the 512 GB Majestic Black Version, unlocked , I'm using Optus, VoLTE, VoWIFI works fine on it.

Hi, did he unlock the phone or was it factory unlocked already?

Was already factory unlocked. I didn't have to insert Telstra SIM to activate it.

Thanks. Is this the exynos or Snapdragon version? I'm planning to buy the 256gb version and use in India. So wanted to check before I ask my sister to buy.

Hi everybody,
On Sammobile website, I found 4 firmware Korean variants. I tried getting more information on the "KOO" variant to see if its a stock Samsung firmware without Carrier Apps/Bloatware without luck. I couldn't get any detailed information whether it can be flashed over any other Korean variant. Can anyone here clarify if its possible and If yes provide further details?
Attached a snapshot.
Many thanks

That is the non bloatware Korean version but it doesn't allow me to flash it. I suspect you have to flash it with the userdata file also.
Thanks for the information,
I have a new phone so No issues with user data. How do I flash the firmware.
Thanks

Hi,
I have successfully flashed the "KOO" variant once with and a second time without "userdata", however that did NOT remove any of the Bloatware/Carrier Apps.
Any thoughts?
Thanks
I disable the 3 apps then hide them from the app drawer.

Hi,
I did disable the apps which is great, but there menu operator items as well!
Edit : Forgot to mention that the boot logo is of the operator as well.
I was researching something about using the PIT file along with the firmware but can't find the specific PIT file for S10 5g.
Use Odin or the modified version to flash combination firmware. Then flash your desired firmware.
This is the only way I am aware to remove all carrier bloatware and boot logos.
Dual SIM

I am particularly interested in this as the 977N variant seems to be dual sim. I notice it also has additional bands to the 977B varient and I would like to put the telstra firmware to ensure operation of VoLTE VoWiFi RCS etc.
The main purpose is to use at home and overseas. So more bands and access to features (VoLTE, VoWiFI, RCS etc. on my telstra SIM and local overseas SIM) when overseas are the goal.
Unless someone can confirm that the 977N with vanilla firmware will support all the telstra features?
Thank you for your assistance
Hi there,
I was wondering if anyone knows whether it is possible to flash the T-Mobile US SM-A716U firmware on the SM-A715F/DS device. Will Odin allow it? Will the device function? As far as I can tell, the chipset is the same, but I wonder how it would affect functions like Dual SIM. (The T-Mobile firmware also has support for 5G, which may not be supported on the SM-A715F/DS.)
Does anyone know what could happen, or if it works? Are there any negative consequences, and could someone explain if the bootloader needs to be unlocked or anything? Ideally, I'd like to get that SM-A716U firmware loaded in the SM-A715, but want to keep everything as stock as possible. I'm also not terribly familiar with Odin., so I'm not sure if the software allows flashing a firmware intended for a different device variant.
Thanks in advance!
no, it won't work. A715F kernel doesn't have property for A716

Hello Guys,
So I bought a pixel 5 from the US (through amazon "003.C1"). When it arrived to my country (Bahrain) I realized that 5g is locked by google to few carriers only.
and I realised that both 5g and VOLTE is not working even though they work just find with my brother S20 Ultra.
I rooted my phone in hope to find a way to enable 5g and VOLTE.
is there anyway to unlock it ? i heard oneplus users had to change a file.
I was able to locate the carrier MBN files. Im not sure though if I can just edit them or I will have to have them edited through magisk. it seems like the files are getting regenerated on boot. unsure though

I tried using the patch in this thread. Interestingly enough after using it now I can see the VOLTE option in the settings. However it doesn't seem to work. Even when enabled whenever I'm on a phone call I can't use the internet

I dont think the variant matters, I think all variants will work with all certified carriers.
I believe somehow we need to add the profile of our carrier to allow for both 5g and VOLTE to be enabled.
If you are willing and rooted try the one on this thread, it is suppose to be for KSA Stc but it might work with yours, however i do not think it will enable 5g, but it might enable VOLTE

What happen pro ? any updates ??
I tried few things with no luck so far.
I tried to unpack the magisk module on this thread and replace the the one mbn he use with others. There is one problem with that though. I cant find an mbm file from a 5G phone that i can replace the original with..
If we can have mbm from another phone that support 5g we might be able to be able to enable 5g.
Another problem is that i do not understand these files well and im not sure if i can just modify one or have to replace it, would appreciate it if anyone got a resource or something i can read to help me understand how these files work and if i can create one from scratch
I succesfully managed to enable 5G connectivity for my Pixel 5 in Finland. Essentially you need root and QPST tool to modify the carrier policy.

I think that in order to enable VoLTE, MBN files need to be modified. But in the case of 5G, modification of carrier policy is enough. I originally posted about 5G and VoLTE in another thread and I'll also provide more details here: https://forum.xda-developers.com/showpost.php?p=83964575&postcount=15

Will give it a try once I'm home and will update back. I really wish it works. But ain't it hard to get to QOST with pixel 5. I tried few times but I will look into the post in your thread and check again

สวัสดีทุกคน,
ฉันจึงซื้อพิกเซล 5 จากอเมริกา (ผ่าน amazon "003.C1" ) เมื่อมาถึงประเทศของฉัน (บาห์เรน) ฉันตระหนักว่า 5g ถูกล็อคโดย Google สำหรับผู้ให้บริการเพียงไม่กี่รายเท่านั้น
และฉันก็ตระหนักว่าทั้ง 5g และ VOLTE ไม่ทำงานแม้ว่าจะใช้งานได้กับ S20 Ultra พี่ชายของฉันก็ตาม
ฉันรูทโทรศัพท์ด้วยความหวังว่าจะพบวิธีเปิดใช้งาน 5g และ VOLTE
จะมีการปลดล็อกหรือไม่ ฉันได้ยินมาว่าผู้ใช้ oneplus ต้องเปลี่ยนไฟล์

Hello,
I wonder if it's possible to convert Thailand variant of S20 FE 5G (SM-G781B) to Hong Kong version (SM-G7810). Both has the same Snapdragon 865 chipset and X55 modem. The reason is that I have to study in Japan for three years and I need LTE B18 during my stay, which is not offered on SM-G781B. I had tried Odin method but it said that Secure Check Fail. I already unlock the bootloader and tried again, but still no luck. What I have to do?
Thanks

You SHOULD receive Tmobile updates once you're on Tmobile firmware and network but I don't think it's something that can be guaranteed. Your Primary CSC can't be changed to TMO and therin lies the problem. In the last couple of years Samsung has complicated firmware and CSC transitions on it's numerous array of devices. Lots of potential users lean to an unlocked device thinking they'll have more freedom of choice but it won't always end up as a benefit. I always recommend buying your service provider's device for full functionality but it doesn't always work out since some users tend to swap service provider's on a regular basis.
I'm on T-mobile's network, month to month, no long term commitment which adds flexibility but even being on their network I didn't aquire their Branded Device. I have the Hong Kong SM-G9980 variant. I couldn't care less about 5G, to me it's the biggest marketing scam since light beer. The only other feature I lose is Carrier Aggregation which much like 5G enables faster download speeds. I can easily have my laptop handle this and transfer files or data to my device. So there's no carrier bloatware, the bootloader is unlocked, I get updates from Samsung typically sooner than US devices and still have Wi-Fi Calling and VoLTE via Tmobile. Most users don't do much research to define which device is best suited for their needs. "I got this great deal on an S21 Ultra but..." We can point the finger at Samsung as well, way too many variants leads to a lot of problems.
