replace firmware question/help - Samsung Galaxy S8+ Questions & Answers

First post here, please go easy on me
Would there be any issues if I were to replace the firmware on my S8+ G955F unlocked (previously with AT&T) with that of a different country/carrier but for the same G955F model? (not rooted)
My carrier hasnt release any updates since G955FXXU1AQDH back in May; I see other countries already have G955FXXU1AQG7 released this week.
thanks!

If the Exynos variants are like the Snapdragon ones, then you should be fine. As long as it is 955F firmware.

How to update 920F?

New to international unbranded models.. I just purchased a 920F S6. How do these models get their updates ota? With a tmo 920T you could check update etc but how does an unbranded model work?
Also, I've seen posts about flashing a France firmware to get updates faster. Is there an unbranded version that gets the first updates from Samsung?
Thanks
hi you would need BTU firmware i do believe

flash earlier version of marshmallow

hi folks,
my 930f exynos is currently on marshmallow BLP2, its an XEU csc, unbranded UK. i would like to go back to APC8 firmware. am i right in thinking that i can just flash the official APC8 XEU firmware from sammobile? i thought i could but also got some advice elsewhere that i couldn't because of the bootloader? confused as i thought the bootloader was unlocked on exynos devices.
gary.

Hi mate
As far as i know there should be no problem , 99.99% of the people had no problem some people had issues not downgrading but with some minor functionality

I find out that my S7-930v converted to 930f

Hello guys
I bought an s7 today , then I found out that it has been converted from Verizon version to International version
From SM-G930V to SM-G930F , I knew because it came with Snapdragon 820
The problem is can I update it to nougat 7.0.1 ?
When I check for updates nothing happened
please help the warranty wont be valid after 4 days
and should I return it ?
First time I see G930F has snapdragon 820, u should try aida64 to see full info of your s7
proof please? How do you know it's g930f with SD?
What do you mean by converted? You sure someone just hasn't flashed a 930F firmware on it which makes it show as 930F in 'About device'?
Boot into download mode, that will show you the true model.
Its not fully converted. It was flashed with g930f pda file. Just download the latest verizon rom (usa) and flash it with odin

my s6 was 'converted' from sprint to international. didn't know that at the time so just flashed another rom onto it (so didn't check exactly what it was before). It was probably sprint version rom with changed name (build.prop?) because only sprint version, not international, could be flashed and was working. as far as i know there is no way to flash international version onto sprint or verizon (especially when s7 versions have different processor)
We see a lot of US S7 models (Snapdragon) faked to look like the International (Exynos) G930F because the US models are bootloader locked, the International is not
Which one would you buy?
Only way to check what the correct model is for sure is from download mode
They can't fake that, and obviously if it is Snapdragon, it can't be G930F

Question Interchanging S22 Ultra Firmwares between different sub-models

Hello,
I have been searching the internet for the past 2 days to find a clear answer for this.
I have received Samsung S22 Ultra SM-S908N which stands for Korea version and when accessing through Sammobile I get stock firmware only for Korea.
My friend has the Samsung S22 Ultra SM-S908E which on Sammobile stands for Asia/Africa and he can install many countries firmware.
The question is, if both hardware are exactly the same in terms of chipset aka. Snapdragon
Is it possible to Install the SM-S908E on a SM-S908N? Did someone try this already - I am assuming the phone is still new and not much of discussion about this but probably someone did this for previous models?
In case I install firmware for the international version and didn't work, boot issue, or completely not switching on.. is it possible to revert back?
Regards,
The

- 1st : you can't install the International FW into the Korean devices variants. Even both at the same chipset.
- 2nd: it's possible to revert back. You must to flash the correct FW ( Korean FW variant ) via Odin on DownloadMod.
I may be wrong but Korean version has 5G mmWave. International version doesn't have

Have you had any luck with changing the firmware? I want to install a European one to my s908N but there seems to be no info on the internets...
Can i ask why you want a different firmware?
To be honest, i dont understand what the difference is between regions... i have a s908e with australian region that I use in US, theres no US region for my phone

Question Flip 3 5G F711U1; XAA => INU

I have got a Samsung Flip3 US unlocked version. Have been using it outside US with and Indian SIM card from last few months without any hiccups. With Samsung Pay working as well.
Now, with the release of 5G services here in India, I'm not sure the bands that Indian operators use are unlocked or not in this. Jio (Indian service provider) says that you're using a non-5G device.
So, I was wondering if I flash an INU firmware to my device. Will it unlock the bands and also let me get OTAs from Samsung? Maybe if someone here did this already?
(According to Jio, this phone is compatible with their 5G network. Also, checked on gsmarena, the international version has the bands that JIO supports.) Since the chipset in international and US is same, I suppose the bands are already there in the device.
Thanks in advance for your help and comments.
Hi Jatin, I don't think flashing your US flip 3 with IND firmware, will fix your problem. The IND firmware is for the F711B model, you are on the F711U1 model. I would not try that. A lot of the F7711B firmware are multi-CSC, but not for the U1 model.
Thanks for the reply, @slysurfer.
I was thinking that since both F711B and F711U1 share the same chipset (Snapdragon 888), the F711B firmware drivers will work on F711U1.
I read some other posts in here (on XDA itself) in which someone with an EUX variant flashed INU firmware to it. Not sure the EUX variant is multi-CSC or not.

Yes, the EUX variant is multi-CSC (to a degree) I can flash any firmware from Europe to South East Asia, but as mentioned we can't flash any firmware from US/Canada.
Big >IF< you can OEM unlock the bootloader you can install twrp and disable the vbmeta and flash a U firmware over a U1 phone and visa versa. But even if you can do all of that it probably still won't work. Personally I'd take it to my local mobile phone stall and see if they can do it.
Thankyou @beanbean50 for your answers.
Sorry for the noob question, . Earlier when Samsung used to release 2 different hardware versions of the same phone like one with Exynos and other with Snapdragon, flashing the other region ROM was not possible.
So, I was just wondering, since both the regions (US & South East Asia) has the exactly same hardware, the networks bands in both of these must only be software locked. Thus, since the US version already has the hardware, can't simply flashing a different region ROM should work.
Again, if there are some other locks that prevent this, it's not possible to flash. Just like if on paper both devices are same, the only difference they have is, they are released in different region.
Also, I checked, both are also manufactured in the Vietnam.

Can you unlock the bootloader?

There is not OEM unlocking in under developer options. I have through other posts and things on how to unlock. I suppose it can't be unlocked in a straightforward like F711B can be.
I suppose this is the hard-stop that cleared my doubts.
Thanks one again, @beanbean50 for your time and answers. Really appreciated!!
P.S.: If you or someone you know have some experience unlocking a US snapdragon Samsung device bootloader, please do share. I might have to consider unlocking bootloader in the future.
