Hey...
1- you cant downgrade from 4xxxx
2- you cant bypass reactivation lock, you will find it blocks all flashes.

I have this issue and tried many things, i know samsung did their homework on how to make these units unflashable, but someone out there knows how? the guy that took out cm.bin and sboot.bin with total commander.
He flashed it saying it worked, but maybe its possible one time for i think once knox is tripped its not letting anything be overwritten flashed through adb sideload, odin .
anyone has any info it would greatly help
thank you

help for install android 6 on g925x (galaxy s6 edge demo live)

hi.
plase help me for install android version 6 on galexy s6 edge demo live.

The bootloader will not be updated, as you need the specific sboot.bin for the LDU (it's different from the retail versions).
You need to remove cm.bin and sboot.bin from the 6.0 firmware package before flashing it. I think if you get stuck in bootloop after flashing 6.0, reverting to my 5.1.1 package is a non-issue (again, i don't own any LDU anymore so i can't confirm this).
You could also try a costum G925F Android Marshmallow rom that is flashable trough TWRP recovery. I'm 80% sure this method works.

Bricked phone, failed stock rom installation

Hello guys,
I tried to install "CRISSCROSS GOES MARSHMALLOW V7.0" rom in my G925F but I forgot what my model/serial number is. All I know is that my phone is G925F (S6 edge international).
Now my phone keeps on rebooting at the Samsung logo page.
Also, I tried to install a stock rom using odin but that failed too (apparently, you can't go to an older software version)
Please help if you can.

(Noob) Please help with G925F

Hi everyone. Im really interested in rooting my G925F S6 Edge. And have seen that chain fire has Cf auto root for the G925F but my build number is is different, to the one that its based on. Does the build number affect the success at all? Or will the G925F Cf Auto Root work on all G925F S6 Edge devices.
Ive been reading these forums for hours now and every time I think im ok to do it, I find users having issues with other models.
Also have read that deep sleep is affected after gaining root access and to reflash original firmware. Ive Searched samfirmware and cant find my exact build number anywhere?
Basically my questions are will the G925F file work for all G925F devices and can I flash any G925F firmware or will i need to pull my firmware of the device or carry on looking for it.
G925F S6 Edge
Build number : MMB29K.G925FXXS3DPF2
Thanks to all in advance

Why are you flashing firmware for an LDU? Is your s6 an LDU? If not then don't flash them....
Search your model number in www.updato.com to find the correct firmwares.
