Changing firmware - Verizon Samsung Galaxy S8+ Questions & Answers

Hey guys,
I bought a phone from ebay (955U) its unlocked Verizon variant. I will use the phone in Europe and want to remove the whole "Verizon" shi*
Is it possible to flash stock firmware from my country even though it's for SM-G955F or it will not work?
Thank you.
EDIT: And one more thing is it possible to downgrade to Marshmallow ? Thanks.

If its an AT&T variant then the answer is no you cant install a custom rom

Did you read my response in the other Note 4 forum?
No root, no custom roms, but CAN Sim unlock.
Edit: that wasnt supposed to sound so harsh. I was just asking if you read it....

Flash SM-A520F/DS with a SM-A520F firmware?

Hello there,
Recently I bought a Samsung A5 2017 in Indonesia (model dual sim) and would like to know if it's possible to put a french firmware (so a firmware of SM-A520F) on SM-A520F/DS model?
Thanks for your help

It would be wiser to use dual sim firmware rather than single sim firmware

Thanks but I don't find any dual sim firmware even on Sammobile....
Is there a risk of brick if I flash with a single sim firmware? Or maybe there's another solution?

I was worried too but I tried to use the normal a520f firmware and it worked fine.
BTW Some apps may not work because they will assume you are rooted eg. S HEALTH and secret mode on browser but you can actually root to get around this by editing a line in build.prop
I'm on the same boat, only with the A3: I've bought my phone as an A320F/DS (that's what the box says, and indeed it has double SIM), but when you check Settings--»About phone--»Model name, it only says A320F (without the DS). And then when you look for firmware updates in Samsung website, you only find for the A320F. Might it be that A320F/DS is only a second, alternative denomination for the A320F, being both identical? (Same would happen with the A7.)

It's one year since your question, but still my answer may help others:
I've flashed a SM-A320F stock firmware on my SM-A320F/DS and it works perfectly. I believe that the A series firmwares are exactly the same for single SIM and dual SIM models.
In trying to sort this out for the s7 g935f/ds, I believe I was told that indeed the F firmware is the correct firmware for both 1 and 2 sim models. There was no FDS firmware at all.

Hi Folks
I have the T837T from T-Mobile. My Question is if it is possible to flash a firmware from the T835?
Also it has a Simlock, anyone knows where to unlock the device?

This will sound stupid but do yourself a favor and sell it on ebay while used ones are still fetching good money and then buy an international korean model, no sim lock plus 6gb ram. I almost bought the tmobile one til i found out about the korean version.

S10+ Korean version 975N much cheaper, any thoughts?

Hi guys,
Here is my dilemma: I live in Vietnam and I can get the Korean S10+ 512GB for about $770 (vs. $990 for the international version).
The phone is SKT branded, but I guess there will be a way to flash the unbranded Korea firmware. Can anyone confirm it's possible?
Also, the Korean version can only take 1 SIM but if it is like the previous Galaxy S, the hardware should be there, it's purely a firmware limitation. How hard is it to install the international version firmware (F/DS) on the Korean version? If possible, will I still get OTA? Will I need to unlock the bootloader?
Thanks for your help!

I don't know that you could install the international firmware on the Korean device. I know the Canadian models (W) can flash the US (U/U1) versions. Id just get some confirmation before trying it as to not brick the device.

N976B firmware question

Hey guys...I have a Note 10 plus 5G from UK, but I am using it in another country (Romania). We have 5G here as well, so this is not the problem. The firmware on the phone is not the latest, but it doesnt find the new one via OTA. I checked the firmware site and there are the August one there. So the question is, if I upgrade via Odin, with one of those FW, will it lock to an UK carrier? Or a German one, or other? Or will it remain unlocked and no issues there?
Thanks!

If the phone is unlocked. The firmware you install on it will not lock it..

Indeed, thank you, did that, all went fine.
I have a similar question. I have a EE unit note 10+ 5g and was wondering if flashing the UK non ee version with a different CSC from samobile will actually change my phone's CSC or will it still detect it's a ee device and still say EVR/EVR/EVR under service provider information. thanks

If you use the multi-csc OXM it will change as per below.
