Soft brick after adb update (bootloop)

I don't know what went wrong with the adb update, but now I can't do anything. I can just enter in recovery mode and download mode.
The phone goes in bootloop (It can just load the first booting screen where there is the Samsung s6 logo) and when I try to do the manual update from external sd or adb etc... It says that is disabled. Any tip to fix it? The device was rooted before the 5.1.1 android update.
Help me please :crying:

Hard Bricked my Galaxy S6 G920F

Hello,
I need your help because I'm in real trouble.
Before I hard bricked my phone I was on the latest version of the Tyrannus Rom.
I wanted to install Xposed but I picked the wrong version.
I flashed it but I got a boot loop.
So i've downloaded the latest stock Rom from Sammobile and tried to flash it with Odin.
Odin got an error and f*cked up my download mode.
Now I'm stuck with a bricked phone with no download mode.
I only got this message on the download mode : "Use the emergency recovery function in the smart switch pc software."
Wich I did.
It downloaded the software and tried to install it but got an error at the begining of the instalation after the download.
After that I restarted it and the download mode was working, so I've tried again to install the stock firmware and didn't worked.
This was the error it gived me : "cm sw rev check fail device 4 binary 3"
Please help me.

Out of curiosity and sorry for jumping on your post but I've have not had any response on my thread and my device has been soft bricked for 4 days now.
How can i go about flashing my device if my PC wont recognise my phone. I've tried everything.
What is the situation you have is there any message or can you turn it on or can you recovery mod or download mod ?
Force it into download mode and do it again, worked for me

Hi so I get the message saying " an error occurred while updating the device software. Use the emergency recovery function in the smart switch PC software" however i cannot get my PC to recognise my device. I have tried 6 different cables, 3 different laptops used 3 different ODIN software versions, removed kies removed and installed drivers, been into my laptop BIOS to disable 3.0 usb drivers also done this through the power saving options. Only thing I have not tried is using a 32bit computer. Surely there is a away to get my laptop to recognise this phone as i used this laptop to screw it up in the first place.
I can get it into download mode, but i cannot get it into recovery mode.
The PC shows a message saying "USB device not rocognised. The last USB device you connected to this computer malfunctioned and Windows does not recognise it."

Yeah I would just flash it, my issue is it will not connect to the PC. For me to flash it or transfer any image to then internal memory i need to have the laptop recognise my device connected. If i had a removable SD card i could just put TWRP on this and go into recovery but the s6 doesnt have this feature either.
I have no idea what to do. I was hoping someone would have a resolution that i have not yet tried and could get my PC to recognise the phone connected.
does odin recognize phone is connected?

Have you tried usb otg?
Try to delete USB drivers and reboot install them again
That Binary Check problem mostly means you're trying to downgrade the firmware. Look for the latest version from fw.updato.com and flash it.

I got the rom file into my phone, i updated the modem and bootloader through download mode and now i cannot boot into recovery or download mode , its stuck on bootloop . what can i do to fix my s7? adb cant seem to find my device now, i think because i didn't turn on usb debuging before doing theese things.

custom binary blocked by oem lock

My A750F was rooted and was running resurrection remix (pie version). It was running perfectly and backed up in twrp. Since android 10 launched I thought to upgrade my phone and installed evolution x. It was stuck in bootloop and after some time got froze and shut down automatically. And now if I try to boot my phone to recovery or the os it shows custom binary blocked by oem lock. I cant even boot to download mode.
most of the solutions to install firmware b using odin but i cant get to download mode.
please help me.......
thanks in advance.
