No, it is not safe.
Your phone has V20q and you want to flash V20o that is an older version firmware ( in the alphabet "o" comes before "q" so :
q =newer
o = older

Flashing an older firmware like you want to do will brick your phone

You can only flash same version or newer.

Writing phone firmware without real necessity is at your own risk.

Downgrade may lead to phone damage!

Please, make sure the phone's battery is fully charged.
Disconnect all other devices from the computer (including phones,
modems, etc.) and close all other running programs.
To avoid errors in the flashing process, use a clean PC (without any
installed drivers for other Qualcomm-based devices).
You should not run any other programs or attach new devices to your
computer during the flashing!

What was initial state of the phone? Why did You decide to reflash it?

According to the Software log, You have downgraded phone's firmware version from V20q to V20o. Downgrading can damage your device.
Can You put your device into Emergency (Download) Mode manually?

I downgraded without knowing about this and bricked this G4. Any solutions?

20i 20o 20p 20q in order for the date build and alphanumeric order a,b,c,d,e,f,g,h etc..

not b,a,z... im sorry for you frend, you have a dead phone now.
