lg g7 weird issue. - LG G7 ThinQ Questions & Answers

hi guys, i bought g7+ yesterday with 6gb of ram and 128gb rom. It is dual sim and It is the refurbished variant with the mode number G710EAW. i bought it and flashed android 9 pie KDZ and it did successfully.
i always root my android device and i was then looking to do the same with it. i tried putting my phone into the bootloader mode by adb command and my phone just booted normally, then i also tried the volume down nd putting in the cable and nothing happens, it only boots into download mode with cable and volume up, no matter what i try, i always end up going straight into the menu after booting.
Then i went into settings to enable unlock OEM and i was surprised because it said ''bootloader is already unlocked''. i was happy to see that but the problem is that i cant boot into fastboot or bootloader mode so its useless because I'm unable to flash anything, is there any other way via adb to push fastboot commands to get root or any other way? i even flashed other region kdz and it works but i cant get it to boot into fastboot or bootloader, it only works in adb and i was unable to stop some bloat with pm disable command, any help please? thanks

[Q] Broken from update to Lollipop (stuck in fastboot)

I've seen some other people with this problem, but there have been no fixes.
The problem is that the phone was updated to Lollipop. It worked for a little bit, but after a couple of minutes lots of programs started force quitting, and it eventually turned off.
When it turns on, it takes about 20 minutes, and then goes into fastboot mode.
If I try to get into download mode, it stays on download mode for around 15 seconds, and then it continues into fastboot mode. Windows does not recognize the phone in download mode, so I can't restore anything from there.
What I have learned then is that I need to flash the laf.img file, which I got from download the official firmware from LG's website by inserting my IMEI, so it's the right version, and then trying both fastboot flash laf laf.img, as well as fastboot
boot laf.img. The problem is that they both fail writing, but it's not just that command. I can't do fastboot erase recovery, or fastboot erase anything, only thing that works is fastboot reboot.
Does this mean that the internal storage is broken? Is there anything else I can do? I can execute fastboot commands, but it seems like I cannot write anything. The drivers seem to be working, as it's recognized as a fastboot devices, but it only says
? fastboot devices
All commands result in a error(failure or something like that. I've removed the SD card as well, as I heard that might cause problems. As far as I know, I need to flash the laf.img to get into download mode, and from there on can flash via kdz.
Help please? This kind of sucks..
When you write a command, does it show on the phone?
You might need to change the driver in device manager. Look for "Android", update driver, browse my computer..., let me pick from a list, and here you'll see 3 different drivers, what you want is "Android bootloader interface"
hi

LG G4 H81510h download mode not working

Hello Gurus,
Well i am trying to boot my phone into download mode but i am continuously getting
secure booting error 1014 and my phone then boots lollipop 5.1 which is stock rom.
my lg g4 model is h81510h build number lmy47d, it is not rooting or flashed anyway.
I want to flash flash marshmallow kdz with lg flash tool but my phone is not booting into download mode, please help or suggest any other method
HALP PLS
I'm having more or less the same problem. I bought a used H815 and it came with Android 5.1 (software version h81510h)rooted and stock recovery. I tried upgrading to MM over OTA but tapping Update Center leads me directly to the App Update screen instead of giving me a choice between software update and app update.
That is when I decided to go the KDZ route but when i tried switching the phone to download mode it went there and in the top left corner there was this 'Secure Booting Error 1014' message and then it restarted in about 5 seconds. I have tried this multiple times with the same exact result.
ADB detects my phone but when I send the 'reboot bootloader' command it just does a plain reboot so I can't use any of the fastboot commands. I also have no idea whether this phone has an unlocked bootloader or not.
Also for some weird reason my phone is not using the MTP mode when I connect it to my PC. It either uses PTP or charge-only depending on what I select but if I select MTP it automatically reverts to the previously selected mode. LG Bridge doesn't detect it and neither does the Mobile Support Tool but I can transfer images just fine. MTP was working last night but it suddenly stopped working and I have no clue why.
I can get into the recovery without any problems.
Please help me get it working again

Same problem with my H811. Any solutions?
I cant get my g4 into download mode. I was able to earlier but it died on me. My buddy has the same phone so I am using his fully charged battery now (mine was around 40$) but I'm still getting nothing. Should I reformat the SD card and try again? I can't think of anything else.

Solution for Hard Bricked LG G4 (9008)

Hi guys,
Some people including me faced Hard brick issue with LG G4, which has now two solutions. the first is temporary, i discovered it and it involves using an SD card flashed with Original EMMC dump ( i tested it with H815 ands H811) , the second needs advanced hardware, equipment and soldering skills ( JTAG) .
The solution that i want to explore is trying to revive the phone with the SD card.
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h811-9008-qualcomm-t3456417
http://forum.xda-developers.com/g4/development/unbrick-lg-g4-h815-9008-qualcomm-t3452853
The H811 dump that i made has TWRP recovery and unlocked bootlloader, so if someone know how to help that would be awesome.
How ???, its very simple. I dont have very good UNIX architecture skills , but if the SoC successfully booted from the SD card. We could see if it detects the EMMC memory ( with parted or with LS command). I personally Tried to brow /dev/block directory from TWRP i hoped to find MMCBLK1 or something but that was unsuccessful , im pretty sure the TWRP or the Soc Does not mount it automatically .
I really dont know How , but i'm very Sure that there is a Solution headed that way , So if some one is Good with Unix architecture and can find a way to soft Flash the EMMC from TWRP ( installed in the SD card ) it would be very Nice
hi,i tried the sd card method...it boots but immediately gives me secure boot error (1006).
i have an h815 bl locked
Hello
I have LG H815 and have bricked. I have installed wrong firmware so it is brick now.
I try new tot file with QPST . but it says fail what s wrong with me?
My computer is win 10 64 bit
You can fix fastboot mode with this way.
1. First you need to download stock rom that your phone supported. extract laf.img file from rom and copy it into fastboot directory
2. download LG Flash Tool and make it ready
3. open flash tool and load firmware and dll that support your model.
open command prompt and make sure you in fastboot directory where the fastboot and related files are stored.
Run following commands.
fastboot erase recovery
fastboot erase laf
fastboot flash laf laf.img
fastboot reboot

Hurry up, now you need to start flash with lg flash tool, if device does not start into download mode. remove battery and insert again, press and hold Vol Up btn and plug USB cable it will boot into download mode. and your device com port should be 41, if not change it in device manager. and start LG Flash tool to load stock rom. once it finish loading rom your device will start and will show you factory test 1, 2, or 3. if it stuck there more than 3-5 minutes. reboot your phone. now you will have welcome screen.
I hope this will work with supported models.

lol, when you see a screen with 0% and a usb connected image, that mean your battery dead
why not just try to charge your phone? or replace a battery?

Hello, well after what happened I thought the same and went to buy another battery and when they tried it did not work, I repeat, not fastboot, no logo, no recovery, only a small vibration without screen, it is not detected by the PC in any of its modes as dead, the detail is that this happened after restarting when I had flashed bootloader N, rom V30, magiistic, I gave it restart and it did not turn on again, so I discard that it is hardware .
I think the problem was that I flashed the bootloader with full aboot, that gave me hardbrick I was told in a forum in Spanish I leave the link I hope you help me thanks

Hey MichaelCV
I have exactly the same problem with my LG G4 H815p. I was running [ROM][H815] H-ROM G4 NOUGAT [v29a] _ LG G4. The phone was up and running and last night I flashed the "LG-H815_29a_Modem_and_Bootloader.zip" to try resolve an issue I was having with the mobile data indicator not showing. I flashed the zip in TWRP, rebooted the phone and now it is bricked. I have exactly the same symptoms as you. Windows and FWUL does not see the phone, no matter what combination of keypressed etc that I try.
Lets hope we find a solution here for it.

Stuck on the AP Fastboot Flash mode

Hey guys, My moto Z Play died on me, and it doesn't budge from the AP Fastboot Flash Mode.
I can do the selections using the volume keys but nothing happens when I try to select one of the mode, including the Start, Recovery Mode, QCOM, Bootloader logs. It just gets stuck there until I restart the phone again to this mode using the power and volume down keys.
Only option that works in here is the restart bootloader option which pushes it back to the same screen.
The problem here is I the USB debugging was not enabled before this happened, so I am not able to detect the phone in either the Adb fastboot or in RSD lite.
Looks like its been hardbricked or the internal storage has been corrupted.
Any suggesstions to be able to flash the stock firmware to my phone.
PS: Its a verizon phone.
thanks

The question is what did you do to the Verizon "unlocked bootlader" phone to get you to this point?

MOTO G6 - Qualcomm - EDL Mode

Hi,
I'm after some advice, how do I place the Moto G5 in Qualcomm mode or EDL mode.
I have entered the bootloader by holding down and turning the phone on, this allows me to use fastboot.
From there I can scroll down to QCOM, but when I press the power button it boots into the normal system instead of EDL mode.
I have also attempted from within fastboot to use:
fastboot oem edl
fastboot oem qcom-on
fastboot reboot emergency
and
fastboot reboot-edl
Although non of these have been sucessful.
I also have access to an EDL cable, although, when I plug the phone in, then flick the switch 10 seconds later, it does not enter EDL mode, it just charges.
The phone sometimes shows as File Storage Linux USB Gadget in device manager, although it is inaccessible, I have updated the laptop to use the qualcomm drivers, although I don't think it will ever recognise it if I can't put the phone into qualcomm mode to begin with.
Any help would be much appreciated.
What are you actually attempting to do?
This mode is generally used to unbrick a device but you have access to the bootloader/fastboot mode and you wouldn't use edl mode to unbrick this device anyway
It's also used on some device to unlock the bootloader but again you wouldn't do that with this device
So without knowing what you are trying to achieve I can't give you any advice
Technically if you start the phone normally then enable usb debugging in dev options then connect phone to PC and in a terminal window where you have adb set up type
adb reboot edl
Not all devices support this mode though and I've no idea if this one does

Without going into too much detail as to why, there are tools I have access to which can be used to take a full back up of the entire memory block of the phone when it is in Qualcomm mode.
I cannot access adb on the device to use "adb reboot edl" so I am limited to either trying to activate Qualcomm using a button combination or via fastboot, unless you can advise another way.
Any help or a point in the right direction would be much appreciated.

Sounds dodgy to me - sounds like you're trying to access data from a phone that isn't yours so I won't be helping

It's not dodgy, but I fully understand.
Thank you anyway.
try fastboot -i 0x2b4c oem ​​reboot-edl (it's working for LENOVO ZUK Z1 and ZUK Z2)
You can try (if you can/have the TWRP image) to flash TWRP and in reboot options select EDL.
In case the bootloader isn't unlocked you can also use fastboot boot [TWRP image name] to boot directly into TWRP without flashing and then repeat, go into reboot options and select edl.
Not sure if it works for you, if it does let me know that I have helped!

I need help too. So, I own a Moto G5s plus sanders. I unlocked its bootloader the day I got it. Didn't keep any backup and rooted it. I Also installed dot os based on android 11. But my 4G Volte connection was finicky. So, I decided to use a Volte zip patch. But, anyways I flashed the zip via TWRP and tried to reboot. But the phone didn't turn on after that. After a few minutes to my shock I understood that I hardbricked my mobile. No button combos, nothing worked. Anyways in my desperation I found a YouTube video showing the use of blankflash to revive a phone and lo and behold I used the procedure to again restore my device. It booted to the fastboot interface. But my happiness was short lived. My baseband was unknown at this point and the bootloader was I dunno downgraded to 0.5 inplace of 2.12. But, more importantly the unlock status was lost. I unlocked it again and all went well. I could even flashed TWRP. but then I realised I couldn't upgrade my bootloader. I couldn’t do anything. It's always gives a "security downgrade", "preflash validation failed" and "permission denied" error. I even tried RSA official rescue tool from Lenovo but even it was unsuccessful. It was never unsuccessful before that. Not even with a unlocked bootloader. I researched for days and tried custom ROMs. I flashed stock images. Nothing brought back my baseband and IMEI. When I type "fastboot oem unlock critical" it gives me permission denied error with a message. "Need OEM signed bootloader." I think the blankflash bootloader is the root of all evil. I need to change it and therefore I need to enter the edl mode. I have tried all adb commands and fastboot commands. The phone reboots okay after those commands but never goes into edl mode whatsoever. I am also ready to do a controlled hardbrick of my device to go into the edl mode so that I can use my device again with a proper bootloader and a properly working fastboot. Please help
