Default 4.4.4 21.11.21 is not downgradable???

I have a consumer edition Maxx (not Dev) with bootloder unlocked via Chinese guy. I was messing with 4.4.4 and decided to go back to 4.4.0 (12.6.3), fired up RSD Lite but ... could not because:

downgraded security version
update gpt_main versin failed
preflash validation failed for GPT

Can someone confirm that 4.4.4 (21.11.21) is not downgradable to even 19.6.3.

It's not possible as of now. The bootloader wont run the software for some reason. Just boot loops. Havent put much work into it though.

You have to remove few lines of code from the xml file.
I have seen a guy who removed 4 lines of code from the xml file and got success to downgrade with unlocked boot loader
