Secure Check Fail (bootloader) - Galaxy S6 Q&A, Help & Troubleshooting

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 see you're brazilian too
How you managed to install 7.0 on your G920I ?
I have DNXXS BaseROM installed right now.

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.

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.

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?

Connect the phone to smart switch and revert to original firmware, after that you can flash 6.0.1 with Odin.

I said no about issues !!
I flashed it and everything works fine. I see a lot of people clears memory/data/cash in recovery mode after installation. Is it necessary if everything works fine on my phone?

if everything seems to work and you are satisfied, don`t do anything..although you can clear cache without anything happening to your phone.

Yes it possible just not the tar file in Odin because that would copy the modem and baseband and that would brick your device but a custom rom or even a stock rom with a installer script should work fine but u might need a call fix :good:
