Has anyone managed to downgrade bootloader from 2 to 1 with odin.This is obviously marshmallow as nougat only has BL2.It's easy for me to downgrade as long as it is BL2 from nougat to marshmallow and back to nougat now done it at least 10 times.Marshmallow started with BL1 on the J510FN before updating to BL2 but I believe Samsung efuse the upgraded bootloader so it is not possible to downgrade the bootloader to BL1 but Mm downgrades with BL2 no problem.Anyone managed to downgrade from 2 to 1.Odin is fail everytime marshmallow firmware is flashed with bootloader 1.

Hi guys. I have a problem on my Note 4 (N910C). I upgraded Android 6.0.1 MM but i can't downgrade 4.4.4. When i try to downgrade, odin says fail. Why is that? How can i downgrade to 4.4.4?
you can downgrade to 5.1.1, but never on 4.4.4 because bootloader is locked on binary version 2 and 4.4.4 had only binary 1
I googled this problem and some people says "download and flash old bootloader" do you know how can i do this? How can i find old bootloader?
I am wondering if there is a way where I can go back to Android 4.4.2 on my SM-G900V from 6.0.1 Marshmallow without rooting the phone, as Verizon has made it impossible to do after an update they applied back in 2015.
You can run KitKat over PB1 Bootloader but you have to have root you would have to downgrade from mm to lp then root then flash a kernel, modem and a rom with flash fire so not possible without root as the qfuse was tripped if you ota'd
Is it posible to downgrade from nougat version WW-14.2020.1703.28 firmware with official bootloader unlocked+twrp+root to a marshmallow version of WW-13.20.10.79 firmware via fasboot then installing the zip file of .79? Thanks
I have an S7 Edge 935A from ATT but I can't downgrade to marshmallow.
Was anyone succeeded downgrade to marshmallow on an ATT phone?
But this is the S5 section Anyway, i guess if your bootloader is locked you need to unlock it somehow first (no clue how) or if it's unlocked just download your phone's firmware from sammobile and flash with Odin.
I don't believe the bootloader is locked. You need an at&t stock 6.0.1 ROM and Odin to flash it. Or you can flash a custom recovery and flash a custom ROM like resurrection remix or lineage 13.1 for marshmallow.
Hi to all, i have S8 G950F, updated with odin with G950FXXU5DSFB_G950FOXM5DSFB_ITV (U5 bootloader).
So i must return to Nougat ( 7.0) : G950FXXU1AQK7_G950FOXM1AQK7_ITV U1 bootloader
but odin failed because samsung blocked downgrade firmware.
So now what i can do for install Nougat 7.0 ? it 's possibile install tswrp with no root and flash with odin 7.0 ? which version i can use?

Some people say downgrading bootloader can be possible through combination file ect but if u never use that file then don't, u can do more harm then good.
Otherwise no bootloader can't be downgraded and your stuck with pie
Search Search Search! Don't be stupid, Samsung bootloader nowaday cannot be downgrade (e.g from U5->U4)...the security check will not pass nor flashing is not possible!
