[Q] S6 Edge (SM-G925F) Upgrade problem - Galaxy S6 Edge Q&A, Help & Troubleshooting

I downloaded Lollipop 5.1.1 from SamMobile.com. Upgrading from 5.0.2 using ODIN 3.10.6 - the upgrade failed and now the device is soft bricked. I can still access the recovery (HOME/PWR/DN VOL), but can't apply the 5.0.2 stock ROM - that keeps failing too with SW REV CHECK FAIL DEVICE:2, BINARY:1 appearing on the device.
I'm not fussed what version 5.0.2 or 5.1.1 gets installed, but how can I get the device working properly again?
All help appreciated.
Update: I've tried using ODIN to upload the stock image and get the following:
<ID:0/003> Added!!

you can't downgrade only upgrade

Thanks for the reply. So how can I push the 5.1.1 upgrade to the device?

if you can't flash your 5.0.2 means 5.1.1. firmware is already flashed..if you had problems with the 5.1.1 firmware you must delete the hidden Img..here is an example

I downloaded 5.1.1 firmware from sammobile and ODIN 3.10.6. when i connected the phone with PC for flashing, all drivers were already updated. Then i hit start after selecting ROM n it failed on the step as mentioned in OP. I tried booting up the phone but it didn't. Then when i again tried flashing the rom after booting in download mode, the error that i mentioned in my earlier post appeared (including error of PIT). Since then the phone does not even shut down. It either boots in download mode or stays at the error screen stating something about something went wrong with the software update and use smart switch.... something like it.... any suggestions.
EDIT: I was running stock 5.0.2 firmware unrooted....
