Downgrading SM-G920F Still Possible? - Galaxy S6 Q&A, Help & Troubleshooting

Hello.
Is it still possible to downgrade a SM-G920F from 7.0 to 6.0.1?
I'm currently on:
Baseband G920FXXU6ERF6.
Build NRD90M.G920FXXU6ERF5.
Security patch 1 June 2018
Reason for downgrade is a month ago the device started running extremely slow. Intermittent disk i/o 90% to 100%.
I've factory reset a few times and cleared cache and it seems ok, but after updates the problem reappears.
I've used package disabler pro to stop bloatware apps running. Still the same.
I'm currently downloading PDA G920FXXU5DQA7 CSC G920FBTU5DQA2 from sam mobile.
Many thanks
Richard

You can't downgrade with G920FXXU5DQA7.
Download and run this;

When you write and select options given above, press "Check Update" and then press "Download" to download factory firmware for your device.
Once the download has been finished, extract the zip file that you've downloaded via SamFirm.
After unzip it, download and run this Odin (even if you have another one);

When you open it, press BL and select file which starts with BL from downloaded (from Samfirm) and extacted zip folder.
Do the same thing for AP, CP, CSC.
When you set 4 files to Odin, connect your phone in download mode.
After that, press Start. When Odin done the installation, phone will restart. When it is restarted, disconnect the cable.
After 1-2 minutes, phone should boot up as completely refreshed device.

Thank you for the reply mate. I'll give it a go

Thank you mate. That worked perfectly. Phone seems to be running much better now

Stock ROM cannot be flashed at all

I have gone through several xda forums. But I think my problem ia different. Whenever I try to flash stock ROM through ODIN into my Samsung Galaxy S6 (SM-G920F) It checks everything as it would normally. When I press start, it goes very fast showing system.img recovery.img and blah blah all. But all of a sudden, it fails
While flashing, it doesn't even take enough time that is required to flash a normal Galaxy S6. All those texts are written in the ODIN window within 10 seconds.
I flashed Noble Nougat Experience 3.1 by @AlexisXDA
But OTG isn't working. So I wanted to revert. But now, I can't. Any help would be appreciated
What's the error in Odin when it fails?
This can determine where the fault lies, also try another usb cable as I've had flash fails due to usb cable.
In the mean time you could try one of the other stock custom roms, otg doesn't work in NNE because of the kernel.

Touch Input is totally messed up

Hey guys I have a g920f and was just messing around yesterday
I installed this rom https://forum.xda-developers.com/galaxy-s6/development/rom-revolution-note7-port-t3461397 with TWRP and now my touch input is all messed up, even in TWRP. I cant swipe in twrp so I flashed some old version of philz where i managed to format everything, I even reflashed my pit and reflashed TWRP but the touch input is still totally messed up
I can't even swipe in TWRP so if I cant fix this my phone is going to be a brick. **** xD
Anyone encountered this before?
Also I cannot restore via Smart Switch or Kies because it says unsupported device. I guess its because i didn't play by samsung rules?

Hello guys,
So I was trying to root my phone. Tried a couple of times but it didn't work. It was never succesfully downloaded with Kingoroot. So I did a factory a reset and tried again with rooting. Didn't work so I wanted to do another factory reset and reboot the system. I accidently pressed reboot to bootloader. Now its stuck. Even when I do a hard factory reset its still stuck. Is there anyone that can help? I feel horrible at the moment
