I recently successfully unlocked bootloader on my H815 EUR version, v20a. I then proceeded to flash TWRP after booting into it from fastboot. I let the phone restart to make sure everything is ok. Then I went back into TWRP to flash SU. After that, I got a bootloop stuck at LG logo. Luckily I was able to use LG Bridge to flash back to stock and get rid of bootloop.
My question is, how come I got a bootloop? Is it worth it to try to root my phone again? I want to be able to use titanium backup to transfer stuff from my old phone. I also want to use xposed.
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.

Hey, I have a LG K10 K425 with android 7, i want a stock LG rom without AT&T bloatware and i want to install TWRP. The problem is i cant get into Bootloader because the ADB command just restarts the phone and my phone isnt detected in Recovery mode, Please Help!
Bro did u find it?
Hello all,
I'm pulling my hair out trying to figure this one out. I have long ago unlocked the bootloader and have crossflashed my G710PM to ULM. At this point my main goal is to flash lineage to this device. I had originally bricked the phone flashing a V30 experimental bootloader, seeing as it was my daily driver, I went an purchased a new phone. Now I'm back to work on this phone as a project, and with a quick QFIL flash, I'm back to square one.
I have only been able to access fastboot when I have the ULM11g firmware flashed to the phone, as far as I'm aware, you can't flash TWRP using this version so I flashed ULM21d in order to get TWRP on it. I wasn't able to get to fastboot from this version so I tried flashing the Euro firmware EM20b. Once again, no fastboot. I've made multiple attemps to find the abl-a image for the ULM version with no success.
I'm determined to get lineage on the phone.. Any help as to where I should start would be hugely appreciated!
Flash Ulm11g again and ab_a then flash ulm20e or 20
Hello everybody! I had problems when installing a custom rom on my LG G8s, I wanted to ask you for help to get the rawprogram and patch files to be able to install the original firmware, the version is G810RA. I tried to create them but failed, nor does it wake up in any other way. It is only recognized by QFil.
I have this same problem
Recently I bought LG g8s and I think I bricked it (Brick) because nothing reacts neither recovery nor fastboot nor even the LG logo. because I wanted to install Windows arm. I unlocked the bootloader and rooted it, and I got to install twrp but something went wrong, I pressed something install to inactive (after OTA) on magisk and turned off and then it does not respond to anything
