[Q] LG G3 - Recovery boot problem

Hi guys,
I rooted my lollipop running G3.
When I tried to install recovery, it says that it was installed succesfully, but when I want boot into the recovery,
phone stay in black screen with "Secure Booting Error! Cause: boot certification verify".
I have tried most methods to install it,,,flashify, window commands and so on ...
Is there any solution to get recovery on my G3 without downgrade to kitkat? ...
(sorry for my bad English)
Thank you, best regards.
No. Only way is to downgrade to kitkat. There is no recovery available for Lollipop at the moment although there is root, and there is a thread on here somewhere that shows how to get recovery on Lollipop by extracting the aboot file, but it is way too complicated for me.

You can try the twrp manager from play store. I'm on a D850 with cloudy 2.5 and it worked for me. Hope this helps.

TWRP with D855 latest LL stock rom v21a

Hi,
I'm curently with the latest LL stock rom (V21a-HKG-XX) on my LG G3 D855 (32GB), and my device is correctly rooted.
I can't find a safe way to install TWRP recovery. I found a lot of method on this forum, but I find only dead links or for different version. Does anyone have links and/or instructions on how to install a working TWRP recovery (with no bootloop, brick, or "Secure Boot Error" and "Certification Verify") with my version of LL.
Thanks to all.
