Backup EFS partition without twrp?! - G3 Q&A, Help & Troubleshooting

Hi all,
I have LG G3 (d855) 32GB variant, It is booted with stock MM 30e firmware, it hasn't root access and there is no TWRP recovery, I read somewhere that I can backup 2 EFS partitions with terminal emulator but I need root.
My question is Can I use dd method to backup EFS with temporary root by KingRoot?
Any one tried it with MM 30e firmware?
Thanks in advance

DOWNGRADE from ZVC to ZVA

ANYONE have a clue how to do this without BRICKING???
NO NEED!!
I downgraded the aboot file to ZV8 , because I wanted TWRP
I read somewhere that there are really no differences other that aboot image from zva to zvc. That being said, I tried PA Rom, and it went thru fine!!!
Twrp is available in ZVC using Autorec.

Best way to downgrade is to use lg flash tools to tot back to zva.

[Q]Did I do something wrong by not going the bump route for twrp

I have the vs985 version on tmobile. I downgraded from 12b to 10b using kdz method then rooted with stumproot. However I didn't use the bump method for twrp I used flashify for twrp. Everything is working well I've made backups and flashed several roms. Just curious did I do something wrong by not going the bump route and if so what could be the problems down the road?

One variant is unlocked and doesn't need anything bumped. I thought it was T-Mobile but I could be wrong.
You wouldn't have been able to flash things if anything wasn't right.
