LG G4 H815 SEA Stuck on LG Logo Screen

So i decided to unlock my h815sea bootloader, every thing went fine. I was able to flash twrp, flash android 6.0 with root and boot into system. I wanted to install xposed, i downloaded v78-sdk23-arm64.zip. I flash the zip and reboot into system. Now i cant go past lg boot screen. Could someone tell me how i can go into twrp? I am able to go into download mode, but LGUP application shows phone as unknown, can I use lg flashtool to flash android 6.0 kdz? OR am i able to flash android 5.1 kdz since i am able to go into download mode. I backed up everything using twrp and have all the files on my desktop.

nvm. I was able to go into recovery and flash genisys rom for xposed framework. For some reason when i try to flash xposed on a stock mm file, phone goes stuck on lg logo.

When did you unlock your bootloader?

I would love to know the answer to that as well.

I was able to get the unlock key when lg accidentally enabled bootloader unlocking for SEA variant on their website. Didn't it use the unlock key until yesterday. Loving MM, so smooth.

There's a guy (shiboby) that is looking for the unlock.bin files to examine to see if he can figure anything out for them. Doubtful anything will come of it, but you may want to send him yours to see if it would help

the only mode that i can access to is emergency mode

Are you definitely flashing the correct firmware? No Nandroid? Would LGUP possibly fix?

yeah of course the correct firmware , many in tot and kdz format , using original flasher and boxes softwares .
i already said that i can only access to emergency mode , no custom recovery on my device

If your LED doesn't blink it means u just got a 'bootloop issue'. LG said its 'loose connection between the components', so high five cuz my G4 died as well, I mailed LG if I can get replacement. Since they replaced people's G4 after the warranty period they should replace it even if the bootloader is unlocked, when they reply I'll tell you whether you can get replacement or throw it away. (Theres no fix for it)

Weird bootloader behavior ... please help !!

Hello guys am basically a Noob when it comes to the new android 6.0+ security system that google included which changed the bootloader unlocking and rooting process a lil bit from the standert ( fastboot oem unlock ... fastboot flash twrp ... flash super su and voila )
let's get to my probleme with my nexus 5x when i unlocked the bootloader with the tool the device has to reboot but everytime i reboot i have to unlock my bootloader again the root works fine but the bootloader keeps getting locked everytime ... problem is that i messed with the boot img in order to disable forced encryption and now i can't flash stock because during the flashing the bootloader has to reboot and gets locked which make the flashing fails ... am on android nougat 7.0 if that matter and if someone have the 6.0.1 (mtc20k) boot image for noforce encrypte please share with me and thanks

You can update manually by flashing the different parts separately using fastboot commands. That way you can skip rebooting after flashing bootloadet

I have the same problem. Bootloader gets relocked every time i reboot. Could not install cm14.1, i just get i bootloop (tried with latest twrp and vendor). Went back to stock with the seperate fastboot commands. It works but really annoying that the bootloader wont stay locked. It worked before i sent the phone to service (emmc problem) and got the motherboard changed. Is there a problem with the bootloader or is it a hardware problem?

Sounds like a HW problem, RMA it again.

Thanks!
Yeah thats what im thinking too. But what do i claim as the issue? Is a non unlockable bootloader a warranty issue? Bought it unlocked from a store.

Ask Google (you can open up a chat with them for example on https://support.google.com/nexus/answer/4582729?hl=en&ref_topic=6023296#contact=1 or other links), for me it's a clear issue, you have the right to unlock the bootloader, however not sure how to demonstrate a problem if you bought it on a store...

All phones that come back from service do so in that state. Seems it's a decision from LG. If you go to bootloader you'll probably see that is says "no rpmb" right after secure boot. This is what is causing the issue, from what I know it is because a certain portion is not flashed on the motherboard replacement
The same happend to me, e-mailed the service center asking why they did this but they never reply

No bootloader?

Good morning,
Having bought a phone LG G4 from China I doubt a bit of their ROM (we never know if they added cookies or what ..) So I decide to get started in the installation of a custom ROM. So already I notice that the phone is already rooted (while it was under blister). Well then I have to unlink the bootloader and I must restart in fastboot but nothing done I can not access the bootloader ?? I tried with the command window (adb reboot bootloader) but it restarts on the home screen .. ditto with an app boot manager, I go back every time on the home screen. How come? I do not have a bootloader or what ??
Thank you for clearing me up.
Sorry for my english

not all LG G4 can be bootloader unlocked only some european and tmobile usa one.
if you had root maybe it was on lollipop phone is bootloader locked.. in lollipop only it can be rooted using system.img rooted. and injecting.. but if you update to MM with locked bootloader it cant be done. no root nothing..
also downgrading in somephones to lower android version bricks phones they have antirollback.. not sure it it applies to all g4. mine does it tmobile.. maybe other can be downgrade. see if yours can at lest to have it rooted..

I don't have the fastboot mode, so you think it's normal? Mine is on LP but I can't update to MM (the category update is missing in settings) wich I think is due to the seller chinese, he did some strange things on the phone I think.

IMEI LS922 / ROM AS922. What to do?

Hi guys,
So I have and LG G5 that I bought recently and when looking into IMEI online I find that my model is LS992 but on my "About Screen" and even firmware it is AS992.
I wanted to flash back the LS992 using LG UP and everything, using "Upgrade Option" but an error shows: "Can not because of LS992 -> AS992."
I need to add that i want to get back to the LS992:
- because with this build i dont have tethering, even with Shareit
- need to reboot the phone everytime so it can be detected into my PC.
Any help would be much appreciated.
