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

Help with LG G4 Model Number

Hi,
I am confused regarding my LG G4 model number.
Because Under About Phone -> Hardware Info it shows LG-H815.
But when I connect it to pc & using adb devices, adb lists it as LGLS991e484402e.
Also LS991 0423 is printed on back of the phone near camera & speaker.
But under the battery the sticker with IMEI displays LG-H815 !
What is the model number ?
I need to find it in order to update it.

Are you checking for compatibility with a rom? If so, H815 is the number you're looking for.

Don't worry about the LS991 number. H815 is the version of your phone, the G4 international.

How are you planning on updating? Flashing a rom from xda-developers? If you're not sure, I'd recommend something like imperium rom, which is based on stock and has much the same behavior but is rooted with more options. Just make sure to download the one for H815. Of course, you'll need to have an unlocked bootloader and custom recovery before you can do this. Do you have custom recovery already?

Is there any way to install custom recovery without Download mode (& of course without root !) ? Because there is one more problem ! I cant get into download mode. If I use Vol up+ & insert usb cable then I get "Secure boot error 1014" & if i use adb reboot-bootloader or reboot bootloader phone restarts normally. Also fastboot mode is not working. Fastboot devices either do nothing or waiting for device ! USB debugging & OEM unlock is on.

The only method we have for our phones at this point is to use Download mode.... have you done some research on that error? Google or the forum search tool?

Yes I have searched for that & some related errors. But almost all of them says that it is because of locked bootloader & to unlock the bootloader I need to enter fastboot mode (Not working as of now) also I have tried many drivers mentioned in the posts (LG universal, LG WHQL etc), LG Bridge, LG PC suit, LG flash tool, LG mobile support tool etc & Also tried the same things on Windows 7.

I don't really know much about fastboot problems, you'll have to look elsewhere for help. Sounds like that's your next step, though. Look for people who can help you get fastboot/download mode working.

Hi Vishesh,
Were you able to rectify the problem and and update the phone ? I am facing the same problem with my g4 H815

With a locked bootloader, you need to install this one:
[TWRP][any G4][BL LOCKED] TWRP-in-FIsH for all LOCKED G4 devices by steadfasterX - it works a charm ... but ... you will need to downgrade to Android 5.1 and root your phone first. Note: You will not be able to install custom roms as long as your bootloader is locked.

An Official Oreo edition for LG G4 h815 has not been released as far as I am aware, nor is it likely to be since very few LG G4's have even had a Nougat version release, let alone an Oreo release.
If you want Oreo you will have to unlock your bootloader and install a custom rom. Can't comment on stock Oreo vs Nougat optimization, nor can anybody else, I suspect as far as the LG G4 - you'll have to check the LG G4 Android development forums to get an idea from the custom rom versions being devloped - AOSCP or Lineage - both are not fully stable as yet though - Nougat versions are currently better as daily drivers.

Hello, thank you for your answer. Currently which version of Android Nougat 7.0 is the best optimized? Send a link.

I'll ask, if you have H815 there's a high chance you can save your time and effort and just unlock it with official LG unlock method.

Do you want to record a video like you enter the twrp from the combination of power buttons by volume down? Please, write in this method did you make your LG G4 h815? > https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
I was flashing this method from this link - but from the command in the recovery terminal it runs to a temporary one. The command for flashing enters the terminal, however, the twrp will not be taken from the combination of the power and volume down buttons. Therefore, write which application to flush root in Android MM 6.0? The application from the Google Play oficialna store to TWRP Recovery requires the root done earlier. I am asking you for your advice.

So, you're saying that you have flashed TWRP to your boot partition and asking how to revert it back? Easiest way would be just to reflash ROM(it will overwrite boot partition) or you can download Titan kernel and flash it instead(download it on PC and use USB MTP to transfer file to G4). If you want to ask how to get to TWRP via key combo then I'll tell you it's quite simple after few times especially if you're good with using your G4 one handed. When phone is off press and hold both volume down and power, then when you feel vibration and see LG logo release power button(but keep pressing volume down!) and the after briefly a second hold both buttons again. If you succeeded factory reset prompt should appear. Then press yes twice and you're in TWRP(don't worry, nothing will be wiped, it's just how LG's bootloader work). I unlocked my G4 with official method like 1.5 year ago(there wasn't unofficial unlock back then) but I did a backup of my stock v20g software with relock possibility(in case of bootloop). Now you can relock officially with Nougat bootloader

Root LG G8 THINQ?

1. Is there a method to root g8 thinq???
As far as im tracking right now there is no TWRP recovery image of the LG G8 ThinQ. I read This Post, and This Post, but didn't test it yet. If anyone rooted it, please let me know.
I have AT&T model. It has the option to enable OEM unlock. The phone is network locked to AT&T.
2. Also, are there any firmware available (e.g., clean one without bloatware)?
I have found This One but skeptical to actually try it out.

Despite the fact that Enable OEM Unlock is an option in Developer Options, when I try to boot into the bootloader, it is unsuccessful. Apparently LG has blocked access to the bootloader on this, as well as other phones.
For the record, I'm on AT&T as well.

Thats kinda lame. I thought that LG wont have same practice with keeping their phones locked as Samsung... Anyway, THIS POST shows supported devices to get to bootloader for LG. Looks like wont have any root any time soon.
What about that firmware without bloatware. Looks like it doesnt require the bootloader?

LG G8 firmware flash

I just purchased a Verizon LG G8 that is unlocked and want to use it on Metro. I haven't gotten the phone yet but I would like to (if it's possible) flash a unbranded firmware. I'm confused about whether I can use LGUP or LG flash tool to do this. Can someone please tell me if this can be done and if so what is the best firmware to flash to have it unbranded with minimal bloat?

I miss the good old days on XDA where people actually came on XDA and there was always someone able to help out. I feel like that doesn't exist anymore. Too many phones and too many different carriers.

I don't think there's a patched LGUP to do this for LG G8 yet.

Holy shiit, someone actually answered my question! That is insane! Thanks for the info man!

Is there a y method that currently works to flash firmware on the LG g8? I would like to flash the stock unlocked carrier unbranded firmware.

There is no way to flash through LGUP or any other tools currently but you can unlock boot-loader root and install firmware package through twrp but doesn't work for T-Mobile or Metro

There is a thread for it and same thing at the g7 thread. Just use octoplus jtag pro to flash the v35 engineering boot-loader to device and from there you can unlock boot-loader and do all the stuff. If you dont have octoplus jtag pro there is a guy who will do it for you he charges i dont know how much though.
