Install custom recovery without bootloader unlock?! - G4 Q&A, Help & Troubleshooting

Hello. Many times i tried to unlock my LG G4 bootloader without any success. Apperantly my G4 is not the european model so it cant be unlocked.
Recently i've heard about app calld RASHR that can install a custom recovery on locked bootloader devices
(here is the link https://forums.oneplus.net/threads/...unlocking-bootloader-on-oxygen-os-opx.417946/).
CAN I MAKE IT ON THE G4? AND IF SO ARE THERE ANY RISKS?

How do we install twrp on h815?

Now since our Lg g4 has been recently rooted how can we install twrp on the h815 without the bootloader being unlocked?
You can't flash TWRP without unlocked bootloader.
Can't root access unlock the bootloader?
Pardon my ignorance of the platform, but can't root access be used somehow to unlock the bootloader? How is it locked?
On a related note, is there a simplified explanation somewhere of all the various layers of the Android experience? I have at least a basic understanding of the BIOS/EFI/LILO/GRUB/kernel/init boot process of a regular computer, but when I was first told about the steps required to install a custom ROM (e.g., HyperDriveOTA or CyanogenMod), it seemed confusing and much more complicated than the standard PC boot sequence. Bootloaders, recoveries, and launchers, oh my!
Thanks.
then how to unlock bootloader (non-EU 815)?
You can't unlock it. There has been no way found yet.

[Q] Can I root without unlock the bootloader or to locked it again?

Hello guys, sorry because may be this is the 50th time someone ask this question but the situation change every day. Yesterday I won from lottery and decide to go from G3 to G4. My model is European H815, I want to ask you can I root G4, change the recovery and e.t.c. without unlocking the bootloader? And also if I unlocked it is their any way to locked it again or to use my warranty? Thank you!!
well you can only root using low effort root(google it or find it here ) But to change recovery you have to unlock bootloader
No there is no way confirmed to relock your bootloader
GOOD LUCK
Thank you! If I root by this way and download Flashify and try to change recover what will happen ? Thank you!
without bootloader unlocked nothing will chnage ( recovery wont be installed ) and when you reboot your phone it will get u error (authentication error #9) as i remember and you will have to flash new firmware using lg flash tool 2014 so i dont recommend you do so
if u wanna change recovery unlock ur bootloader
you are welcome anytime
I did not get it, I hope you can light me up:
1. Doing root using low effort root means rooting without unlocking bootloader? (because I flew over the thread and did not read anything about it)
2. If I do unlock Marshmallow's bootloader, what happens when I downgrade to Lollipop via flashing proper KDZ? (I would guess that the unlocked bootlader will be overwritten!? So flashing Marshmallow again would end up in a locked bootloader, doesn't it?)
thanks
You can root lollipop without unlocking bootloader but with marshmalow you can't, you have to unlock the bootloader.
You need an unlocked bootloader for custom recovery.
Bootloader unlocking is a one way operation , you can't go back.
