Can someone help me find any download source of this firmware,
Galaxy s6 DUOS, SM-G920FD
As I wanted to Upgrade my galaxy s6 duos to andorid 5.1.1
But unfortunately, from SamMobile firmware website, they do not have that kind of firmware on my phone.
Can you please, if any, share your firmware . Any help will be appreciated.

I think it's the same as g920f
I have g920fd and in settings it reads phone model as g920f and baseband as G920FXXU2BOFJ whitch is the same for g920f
i dont know if it has any additional software to handle dual sim or not

Thanks a lot. One more question. I am french but based in the usa. Out of all the 920f firmwares which one would be the most generic. I see a bunch that have "unkown" listed as the country. Which firmware would be the most generic?

Secure Check Fail (bootloader)

Hey guys
I'm trying to install CYV version of 7.0 Nougat update but as soon as I hit START in Odin, it fails and my phone shows this error: SECURE CHECK FAIL (BOOTLOADER).
I'd like to know how can I fix it and continue with the installation.
Also, do any of these factors influence on this error?
1. My phone is G920I and the firmware is for G920F.
2. My region is not CYV.
3. I have TWRP 3.1.0 installed.
Thanks for your help and attention.
G920f use a different bootloader than G920i, you can use a custom rom based in a G920f firmware like fastrom but you need a G920i bootloader and módem installed, you cant flash a G920f firmware in a G920i. Flash a G920i mm firmware and start again

I'm having the exact same issue with the exact same error message on my S6 G-920P Sprint phone when trying to flash to T-Mobile. There has to be a work around because flashing from Sprint to T-Mobile works flawlessly on my Sprint branded S7.

Hi! I wanted to downgrade from android 7.0 to 6.0.1 to install Xtrestolite after. I have csc VD2 and tried with stock fw XEU and VD2 from sammo..but all i got was error :use Smart Switch
Questions:
Can I install Xtrestolite having android 7?
Why i couldn't downgrade to 6?

That is what I tried to do. I used two versions of Odin and tried to flash 6.0.1 VD2 and XEU but i got an error after a few seconds and soft bricked my device. I tried to use Smart switch to recover but got stuck at 93% (2 times). Eventually I flashed 7.0 VD2 with Odin again. Back to where I started

J7 SM-J710MN not works after update to nougat

After I upgraded my J7 SM-J710MN to the Nougat android, the touch no longer works. I'm from Brazil and tried to flash through odin 4 rom stock 6.0 versions and FAIL always appears. Only the Nougat version I was able to flash but it did not work.
Which firmware version should I install? What to do?

That problem you have in your mobile is because you have installed Nougat 7 with the binary 4, you can not return to MM, here I leave the Original firmware TTT (Trinidad and Tobago) operator-free, before installing the firmware performs complete wipes, thus avoid Bugs in the New firmware.
