If downgrade is not possible then there is not much we can do right now as I see. I am trying with the new z3x samsung tool pro software which has the model listed as supported but the problem is the codes described to get the usb port to DM+MODEM+ADB are not working at all. Hope someone could have a clue on this one.

Yes it is!!!
I already do this many times before....
U cannot go down to 4.3 but can still go back to 4.4.2, use SSU.APK to unlock and go back to lollipop...

*When I did his for the first time I had nothing to loose before, this S5 had IMEI problem and was not useable, and the ADB+DM+MODEM was not detected in Z3X....
So I had to downgrade it for the whole repair process....

Here's another way to do it:
1* Install TWRP OR CWM RECOVERY
2* DO A NANDROID BACKUP
3* Copy a 4.4.2 Nandroid backup to your SD or EXMMC in the same place of the Nandroid backup u did before.
4* Go to Wipe option and wipe:
- data
- System
- cache
5* Then go restore option and restore the phone with the 4.4.2 Nandroid backup u placed.
6* Wait for the process to finish and do a simple factory reset and reboot the phone.
7* And enjoy being back to 4.4.2
-unlock the with SSU.APK
And update back using odin to 5.0 now.

Yeah many times....
But if it froze on Samsung Logo I go back into recovery and flash this kernel file:
KT-SGS5-LP5.0-TW-G900-04.06.2015
Google it and and everything will be alright....
Customers never comeback for any issues so far....
