Rooting the H815: Should I unlock the bootloader or not?

I have received my new LG G4 H815 (EU) phone today and I definitely want to root the phone. Now I'm asking myself whether I should unlock the bootloader or not.
As far as I understand, there are two completely different options for getting root access to the device:
1. Register on LG site, officially unlock bootloader, install TWRP image via fastboot, install root via TWRP
2. Walk through the instructions in this thread:
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
According to the thread you should disable OTA upgrades after rooting it and there is always the possibility that LG patches this rooting method with future Android Upgrades. However, I do want to upgrade the Android system image from time to time (LG will probably provide an upgrade to Android 6.0 sooner or later). Will upgrading the Android system (without loosing root) be less problematic when I unlock the bootloader now? As far as I understand it so far, you can easily root it again after an upgrade if you have unlocked the bootloader. Is that correct? Can I still use OTA upgrades when the bootloader is unlocked and TWRP is installed? I don't mind running fastboot to reinstall TWRP after an upgrade but I don't really like to manually download each Android upgrade from shady mirror sites instead of using the official LG OTA updater.
I do know that unlocking the bootloader will void the warranty and that some Apps may refuse to work no an unlocked device. I'm ok with that and I want to have the phone permanently rooted and install updates (without loosing root) with as little trouble as possible.
Since unlocking the bootloader will wipe everything, I want to do it either now (before setting up the phone) or never. So what would you recommend?

[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.

Need help with which firmware to flash

hello, I have the sprint ls990 model, basically I was messing around and I soft bricked the device, now its stuck on the LG logo. i tried factory reset from boot into recovery which didnt help. Now I am trying to reflash but I am confused with which firmware to pick since I want to be able to have root access and sim unlock.
I was already rooted and sim unlocked on ls990zv6 kitkat firmware (not sure about bootloader) before the brick. So my question is now if I flash the same firmware or the new ZV8(lollipop) using lgflashtool , will this remove the root and sim unlock?
If it removes it, then what option I have? Because Ive read you have to downgrade to ZV4 to root and sim unlock, so if my bootloader is not unlocked, then I will brick the phone???? And if I remain on ZV6 or update to ZV8, And then if root, sim unlock is not possible, then Im stuck with that because I cant downgrade with locked bootloader????????
Please answer this for me. thanks

Need help about 6.0.1 update.

Well I bought my zenfone 2 it's been 1 year ago, and on the end of 2016 I rooted it because I don't had hope on 6.0.1 update anymore since it was full of bugs. I still on 5.0 and now I want to update to 6.0.1 but I don't know how. My bootloader is unlocked and I have TWRP I was planning on flash the stock recovery and then push the update but there is the problem. Can I update with unlocked bootloader? Or I'll need to lock it again then update? I really can't bare with the 5.0 firmware anymore and I need to update. But since I don't have a constant access to a computer I don't want to brick my phone.
Yes, I tried search for tutorials online but all I get is how to unlock bootloader on zenfone 2 on the 6.0 firmware and how to root it..but I don't get none answer to my question so I hope someone here can help me.

OEM unlocking and flashing TWRP on a SM-G96W Canada Snapdragon variant

I would first like to know if there is still a bypass to the 7 day waiting period to OEM unlock.
And 2 I would like to know if there is a way to flash TWRP and if not, is there a way I can root my phone and THEN flash TWRP with the TWRP app?
I found some rooting guides but they require me to flash a file to my phone which I obviously can't do rn as my bootloader is still OEM locked obviously.
Any help would be appreciated
Thanks in advance!
