I am currently on android 5.1 and I want 6.0 so I heard I can update it with lg bridge.After that I have to unlock bootloader so I can acquire root permission.Would either of them make my phone not updateable with officials(ota)?
You probably will have to manually upgrade with a KDZ file. Maybe the real question is... is it worth to unlock bootloader and lost warranty?

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?
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.
Hello all
I have been searching effortlessly for a way to root my G4 H815P AME but i could not find anyway not to mention that lg has no plans at all to unlock my bootloader as of my last communication with them.
I am on V20d version of MM.
I know I can flash the whioe img pre rooted with LG Flash tool but could not find any variant firmware for my H815P.
Any help would be very much appreciated.
Hello there!
I have a locked H815 and I've had many issues with it, especially when I upgraded to 6.0 and V20D. I've got it back from repairs and it's been downgraded to Android 5.1.
I saw that it's ok to use LGUP and flash 5.1 and 6.0 firmwares and that doesn't require an unlocked bootloader nor root.
Now, I want to ask if I unlock my bootloader, will I still be able to receive OTA updates? Or updates through LG Bridge?
Also, if I install a custom ROM right now, will I be able to successfully flash the stock firmwares and have the phone as it was just with an unlocked bootloader?
Thanks!

Hello there, i got an LG G4 h815 few days ago, when ever i get new device first thing i do is root it, and it was always very easy for me.
with this g4 i got problems, try to go to LG website and unlock bootloader, it say i cant cause my device is h815 taiwan, so i read more in google and understand official unlock is only for the euro devices.
so i google more try to understand how can i unlock it unofficially, and found nothing, as well as try to google for a way to root it with out unlock bootloader, and also coulnt find.
im sure im missing something, cause i dont think its possible that there is no root for an old device, any help on how to root my phone?
thanks a head.
Lots of people here have H815 TWN...please can some one make a specific thread for rooting or installing xposed on Taiwanese H815 without the risking of bricking or bootlooping the device...meaning successful rooting ...

unfortunatelly you cant unlocked till today.. maybe later if someone can do it... but you can add root to locked bootloader... i have not tried this method.. i tried similar to h811 tmobile.. but its the same procedure.. mine is unlockacle but i dont want to with the bootloop issue... unlocking bootloader voids warranty. and root too but you can always try the kdz that disables the big cores and undo the root..

thank you, i found the root for locked bootloader, i done it, but its only for 5.1 android, and i still cant flash roms, only one rom witch they make for locked bootloader, so after all the process went back to unroot 6.0 androis >:
hope some1 will break this bootlock .
