flash earlier version of marshmallow - Samsung Galaxy S7 Questions and Answers

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.

Is Firmware Region important?

Hi,
I wanted to know if flashing a firmware from another similar region was possible?
For instance I have the g920I from Australia and I noticed that the New Zealand version has been updated today.
It seems that if you your phone is unlocked to any provider you can then flash any firmware but I would like to confirm please?
Cheers

No it doesn't make any difference. I flashed the New Zealand on my G920I and it actually fixed some issues I was having. So it is safe.
If you flash the wrong firmware, you and your phone might start speaking with an accent. I'd recommend just flashing firmware from your region.

[Q] What Variant is my S6?

Hello,
My phone is a SM-G920F w/ 5.0.2 installed. The Baseband is G920FXXU1AOCZ build number LRX22G.G920FXXU1AOCZ . The only reason I'm asking is because I've seen others get an OTA for 5.1.1 but I haven't yet. I was wondering if I could Odin the phone to a UK variant?
The seller from the shop said it was a phone from Isreal flashed with a Region Free Firmware? but when I check the knox it was still intact. Is there any way to find out more information about the phone?
Thank you!
I have the exact same question. I have the G920F international unlocked model as well, using it on AT&T here in the USA. Phone's working great, but no update to 5.1, despite reading reports that Samsung has pushed 5.1 to the international variants. Is it because we're using the phone in the USA? Will we even get the OTA update, or will we have to update manually using ODIN?
Here you go UK ROM 5.1.1 BTU ready for you to flash:

I didn't ask the original question, so my apologies. But I was wondering if you had any advice on how I should proceed to update my device? I have the G920F that I bought unlocked off of Ebay and using it on AT&T here in the USA. It's working fine, but it says there are no updates. I don't even know if it'll even get an OTA pushed to my device since I am not in the originating region?
Should I just wait, or is it safe to go ahead and flash one of these 5.1 roms with ODIN that are for the G920F? If so, which one should I install? I think the first one available for the G920F was the France one. But now there are others. Does it matter which one I install? Or would I have to wait until a North American rom is available?
Thanks!
For reference, my build is G920FXXU1AOCV and my CSC is G920FOJV1AOBL. Not sure what those mean or how it applies to my situation?

Ita still best to stick to your working 5.0.2 ROM and wait for official 5.1.1 OTA update which should come soon. Flashing exposes you to risks like bricking your S6, tripping Knox and voiding your warranty. If can't resist the itch then flash away.

Thanks for response, I assume it's the same risks as me? I also wanted to get rid of the Israel edition and make it UK, will I hit any risks?
Risks are still the same. You can also consider flashing this Israel 5.1.1 stock ROM below:

Thank you again for your replies very helpful. Phones seem to be getting more complicated, but I'll root and install custom rom when warranty is up

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 a different regional firmware?

Can I flash a different regional firmware to my G930F? My G930F came with Trinidad and Tobago CSC, build number and I want to flash the UK firmware so I can receive the latest update.

Will I be able to unbrick it through ODIN if something goes wrong? I want to do Dual SIM to Single SIM conversion just for the sake of quick updates.
I'm not sure how different the international S7 variants are from each other. But here in the US they are all the same except for the software so I heard. I got a Sprint S7 to which I wanted to use on T-mobile. So I flashed Tmobile's firmware on my sprint variant and turn out great, have wifi calling and everything is working great.
So it couldn't hurt to try it if you know what you're doing and like you said, worse is just odin back to your stock firmware.

I have the 920F S6 that came with UAE firmware. I flashed XEF France firmware with no issue and assume the same would be true on the S7.

The UAE s6 you had was Dual SIM. And you flashed Single SIM firmware, right?

International variants have two versions. Dual SIM and Single SIM. Will doing this ODIN process void warranty or trip any counter?
I flashed the UK firmware on my s7 and it worked. I had the Trinidad and Tobago firmware before. I have the latest update now.

I see. I'm certain it doesn't void warranty but not 100% sure. No knox tripped for me so I assume you'll be ok also.

It shouldn't had been with UAE firmware. It was most likely US/International version. BTW it was better getting one from Souq instead of Amazon. Haven't seen Amazon mostly do international shipping on smartphone.

for future reference, you should check frequencies used by both carriers before flashing

if they dont match, you could have trouble with internet speed or battery life.

Fail to Upgrade SM-G920I (Spark) to 6.0.1

Hi Guys,
I've bought a Galaxy S6 (SM-G920i) on B&H unlocked, and it comes with an Australian firmware (SPARK) 5.1.1.
I've downloaded an unbranded firmware from sam, but I can't installed. It has failed before instalation begins.
Has this firmware (SPARK) any kind of lock that can't allow me to install an unbranded firmware? I want to stay with the phone stock and with an unbranded version of 6.0.1.
If anyone can give me a clue, I'll really appreciate it!
Regards,
Power

check your csc, it may need to be changed if spark has not as yet released a 6.0.1 upgrade.

Thanks for your reply Cosmic! I'm trying to push the firmware via Odin. I think CSC should not a problem at this point. I can't understand why I can't flash an stock firmware via Odin. I'm starting to think that it has any kind of lock.
Anyone had the same experience than me?
Thanks in advance,
