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)

LG simply sai that they will not repair it and they gave me the phone number to their 3rd party service that REFUSED to repair my phone, I'm done.

tried to kdz stock 20i but i relocked bootloader in adb first while rooted with twrp

i was rooted with twrp bootloader unlocked on 20i firmware. I wanted to kdz back to stock .I Couldnt get lg flashtool 2014 to finish extracting firmware all it did was roll back to 80% then says connection to server timeout. So i fastboot relocked bootloader not knowing if this still applies like how on a Nexus device where you never OEM Relock until you have flashed stock. I FIGURED Lg KDZ flashtool on a lg would do all that . At this point i am stuck on secure boot error 1003 "BUT" i still have download mode . Lg flash tool still wont do its thing it analyses phone to 33% then rolls back to 25% then it goes to 100% ,then it starts extracting 20i kdz that i downloaded but then stops at 80% and says error connection timeout.
I ALSO have no COM ON THE G4 download screen. I know i cant be hard bricked. If i knew how to get back into fastboot mode i would oem unlock again because it was still checked inside settings before all of this. Ihave drivers installed as well
Any ideas?

Does the LG G4 have a flash counter?

Does the LG G4 have a flash counter? I claimed a replacement warranty from Verizon after being stuck in a boot loop. The phone was on stock ROM with root. I flashed the stock .kdz (VS9611A_05) and the phone still will not boot. However, now inside the System Recovery menu the phone says "Original" when before it said "Modified". Is there a way Verizon can find out that the phone has been rooted? (Being rooted did not cause this boot loop) Apparently I will be charged a $299 fine if they find the software had been modified.
Thanks for any responses!

unlocking the bootloade voids your warranty.. only way is to send it to LG... or used the modded KDZ to disable big cores... in case you ncaat fix it. or get new motherboard..

So its not software related? Is there anyway to disable the bootloader unlocked message?

bootloop not software but hardware... but you could try flashing KDZ using LGUP. ive seen some claim theirs worked after flashinf stock firmware if it continues then hardware but most likely its hardware..
mines is unlockable.. and trying to keep it that way for the same reason... ive seen a post that says it can be relocked...
heres is the post.. i would like to ask you a favor if you try it.. make video of it .. to prove it works..

This is the reason why i swap my G4 H818P to Korean Variant G4. The Bootloop problem. Korean Variant is perfect for me. Strong 4G signal and no more SMS Limits in Marshmallow official update.

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.
