I recently bought a LG G2 for a great price, when I got it back to my home and turned it on, I discovered something. I found that it wouldn't boot and Download Mode is REALLY BROKEN. I can still get into TWRP, but the UI is in ruins and I can't navigate. When I try to enter Download mode, I get used to get an error code. Something like: error: cannot verify download mode, or something like that and when I try for a normal boot, I just get stuck at pixelated display. Really what to get this phone working, I can't disassemble the phone and I don't have the tools nor money to get said tools. When I power it on, I get an extremely pixelated display and I don't see the LG logo anywhere when I boot it up. I have been able to get the logo to appear once or twice. There is no warranty on this phone, can't afford to send it back to LG. I am getting very stress out over this device.
Things/Methods I have tried:
1) I tried to enter Download Mode, but it 'crashed' per se, and it then proceeds to wreck my PC, by flooding my display with Windows Explorer pop-ups.
2) Tried a normal boot after I restored my previous ROM before this stuff began, and it did no good.
3) Tried to get into fastboot, but apparently, it doesn't seem to exist on it, so I can't use other methods.
4) I downloaded the appropriate KDZ file for my phone to try and flash it back to stock, but the LG Flash Tool didn't recognize my device. I attempted to try and use the Minimal ADB and Fastboot tool, but it didn't to anything for my phone. Everytime I entered a command, it's say "<Waiting for Device>" and then it'd proceed to freeze there not do ANYTHING.
5) Tried a normal boot and that did nothing.
6)Tried using the ADB Sideload feature in TWRP, but that proceeded to crash the UI even more and then the device would freeze.
7) Wiped the Dalvik, System, Data, and Cache and then attempted to restore the OS, but then when I tried to get it into the the OS, it'd just boot loop at the pixelated 'boot screen', if that's what you'd call it.
8) Tried to get into fastboot, through Minimal ADB and Fastboot, but nothing happened.
9) Tired to fix Download Mode, but then the error arrives and then the device proceeds to a completely black screen.
10) Contemplated on physically removing the G2 from this plane of terrestrial existence.
I would appreciate the help. I want to get this phone back to Stock Firmware and then use it as my primary device and sell my Moto G.

First verify model number of the phone viz D802/ D803/ 802T. Download original firmware file and Flash appropriate bootstack, download bootstack from https://github.com/lg-devs/bootstacks here.
After flashing boot stack, connect phone with cable to PC.
Use key combination (depending upot the bootstack you choose) to boot into download mode.
Use LG Flash tool to flash original firmware file.
You are good to go!

Download your recovery for your model, try flashing in TWRP if you can, then flash correct ROM for your device *Link*http://www.gregtwallace.com/lgg2-projects/twrp/?version=2.8.7.3
first thing you should do is to know if phone was refurbished, some phone claim to be d802 and they are not..
you do this by opening phone and checking MOTHERBOARD model or variant.

I opened up the phone, to an extent, and it is in fact the model I thought it was. D801

I don't understand how I can flash the boot stack when I cannot connect my G2 to my PC and it work. When I put it into 'Download Mode' I get an error and it crashes, then a bunch of unformatted drives appear and I can't use a flash tool, because my PC doesn't detect that it is connected to the computer.

I can't get anything into the TWRP recovery, I am able to get into TWRP. Outside of that, I can't do much. I can restore my back up, but both of them were post-crash and I can't do anything. I tried the ADB sideload, but it wouldn't launch the file. I enabled MTP (Media Transfer Protocol?) but I didn't see my device.

Update: My sibling, when they came over, smashed the screen out of it, so I can't do anything with it until I get the screen replaced.
I ran into a bit of an issue and am stuck with a bootlooping G6 US997.
What got me into this pickle:
I unlocked the bootloader
I flashed TWRP successfully, by:
Running fastboot flash recovery TWRP.img
Unplugging USB and holding Vol- and Power from fastboot, then lifting and re-pressing Power when the LG logo appeared
Hitting Yes, Yes
Being in TWRP and allowing modification of System
Formatting Data (Wipe > Format Data > Yes)
I installed the DM verity and encryption file so that it would boot
I wiped Cache/Dalvik
I rebooted into System
It booted successfully so I went back to TWRP and installed Lineage OS, Open Google Apps, and the Lineage SU addon
This booted successfully, so I went and with OEM unlock disabled booted into fastboot to see if I could get rid of the annoying orange screen at the start saying that the bootloader was unlocked
To do this, I ran fastboot oem lock, not seeing/ignoring the red text at top telling me to Please check "Enable OEM unlock" in Developer options.
I then rebooted with fastboot reboot and I encountered a red warning: "Your device has failed a routine safety check and will not boot." It is now in a bootloop at that screen, cycling between black, the LG logo, and the warning.
I managed to enter recovery mode (with the key-combo) and got the stock recovery "factory reset and wipe" option, which I had been previously getting when entering TWRP, so I selected "Yes, Yes" and then it went back into the bootloop, completely avoiding TWRP.
Where I currently am:
I can get into fastboot mode (Vol- with usb plugged in) and I can get into the factory reset mode which is the gateway into TWRP. I cannot get into TWRP, and I cannot flash anything, boot into any images, or unlock the bootloader ( Please check "Enable OEM unlock" in Developer options). If I could do that I think I can get it fixed.
My questions:
How can I do the OEM unlock without access to Developer Options? (I have the unlock file to flash, just need access)
Or How can I bypass the red warning page and boot into Lineage OS?
Any help would be appreciated, I really would like to get this working.
Have you tried to boot in download mode and flash the original firmware with LGUp+Uppercut?

I've been trying to, I forgot to update the post though. I found the US99715a_05_0908 KDZ, and I installed Uppercut, LGUP, and the drivers from the Uppercut thread, but whatever I do it never recognizes the device. And when I go into download mode it quickly pops back out to the warning screen after about 10 seconds. After the warning it reboots in 10 seconds, I have a pretty small window.
I was thinking of trying LG Flash Tool 2.0.1.6, yet I haven't figured out how to use it yet. I may try more with Uppercut, maybe different drivers? If there were a way to keep it in download mode longer, that would really help. Thank you for replying, I've seen your name around the forums!

It looks like it might still be in download mode, but interrupted by the warning, the way the screens flash. After the warning it reboots in 10 seconds, I have a pretty small window.

I know this could be a stupid question, but have you tried to run the unlock command? If yes, what does it says?

You can't, fastboot is a mode that allows many things but it's not a God-like mode where you can do everything.
By locking the bootloader while having unsigned partions flashed you have essentially hard bricked the device, and if the only way to flash stock signed partitions (lgup+Uppercut) doesn't work it means that you have to find a way to boot the phone in qhsusb9008 (usually by hardware) and try to flash a tot file, if there is one.
Sorry but is highly unlikely that you will able to recover your G6, hope to be wrong.

How might I go about doing this, or is there a chance I can actually access LGUP and have just been messing up so far? If there were a video of what using LGUP and Uppercut properly looked like, that would be really helpful.
Also, is there any hope of LG or a phone store with LGUP being able to fix this (for less than the price of a new G6)?

It depends on how much it'll cost to you a new G6, they could ask you maybe 200-250 bucks.

Go in fastboot with the phone connected to the PC, keep pressed vol- and power until the phones turn off in that exact moment leave those two buttons and keep pressing only the vol+ one, this should bring you in download mode, if it stuck then you could use LGUP and Uppercut, otherwise there is nothing software related that you can do, imho obviously

Guys, need help !!!
I have tried to install SEA oreo version on Indian phone via LGUP... Flash was successful (100%) but it got stuck on LG Logo..
Procedure followed for H870DS (IND)
1. Downloaded SEA Oreo KDZ File (H870DS20a_00_OPEN_SG_DS_OP_0518.kdz)
2. Installed LGUP... Made new Common folder inside C/Prog file/LG/Model
3. Extracted DLL file from KDZ & renamed it LGUP_Common.dll and kept in Common folder
4. Entered in download mode
5. Opened LGUP.. selected KDZ and Upgrade..
6. Boom.. 100% completed.. it has shown that phone is rebooting..
7. But then it got stuck on LG Screen
I cant access recovery now
I can open Hard Reset option (Vol down+Power) only.. Made hard reset but no use
I cant enter in download mode
I dont know if it is charging or not
It is not even switching off by pressing power button for long time
Pl help me...
---------- Post added at 08:33 PM ---------- Previous post was at 08:30 PM ----------
it has anything to do with "Enable OEM unlock" in Developer options"
There is a way to enter download mode. Just hold down button and power button. Just when you see LG logo leave power button for a second. Push power button again and hold with down button. Now press yes twiche for the hard reset prompt. Now IMPORTANT, when screen goes black immediately press and hold up button. While holding up button plug usb cable into the PC. Now use Uppercut 1.0.0.0 and flash your kdz.
Same issue, Just that I was trying downgrade to Nougat. Oreo messed up my phone to the extent that, none of the sensors (including Fingerprint are not working). The load was a success, but after 1st restart it went into boot loop.
I only had USB Debug enabled in the DO before this issue, so it might work with the OEM unlock dissabled.
Software needed...
LG Bridge
Meathod...
Please charge the phone before this is done, at least 80%, will be better.
Connect the computer with LG G6 H870DS (Indian), might work for all models. "not tested"
If the USB debug is enabled, you will hear the USB disconnection and connection notification sound during bootloop
When you hear disconnection sound, press the "volume up key" until the Firmware Update mode appears
Once you are in Firmware Update mode, the USB connection will be stable (In bootloop, it keeps disconnecting)
Disconnect the USB cable
Start LG Bridge/Software Updates, connect when App asks to connect the phone
This will update you phone to the latest official software update..
This solution can work for all phones that have a hardware based menu to get into Firmware Update mode, definitely works on all LG phones to get out of bootloop. I have tested on LG G2, G4 and G6 Indian devices.
And a suggestion to all mates is, to enable USB debugging and the OEM unlock as soon as you get hands on your new devices. Always saves the hassle of running around the LG service center, its a big issue in India at-least. I love LG for its hardware quality but sadly LG smartphones have a bad history of software issues
So i wanted to create a key mapping for android over my android game using my xbox one controller but all the apps that allow it require rooting. So i quickly came here to see if it was rootable and surely my model was listed. LG k20 Plus MP260, So i go and download adb tap my build number, do the usb debugging, allow oem unlocking, downloaded the Lg drivers, moved the recovery.img to the adb file folder directory, moved the super user Zip file and the no-verity-opt-encrypt-5.1.Zip to the internal storage of the phone. Then run Shift+ Right click adb reboot bootloader using Windows powershell command line and i'm in fastboot mode (I can also just power the phone off and hold the volume down button and plug usb into phone to get into it). So i use fastboot devices to make sure the computer recognized my device and it does. Note: (the bootloader is already unlocked) Then i use fastboot flash recovery recovery.img and it flashes. what happens next is well. I use fastboot reboot and well i get "Your device software cannot be checked for corruption lock the bootloader" and below that it say "PRESS THE POWER KEY TO CONTINUE" i press the power key and it boots up normally. In the video's i've watched they say it will boot into the system twrp and my phone is not doing this. I'm willing to let someone team view me and skype me so we can work this out together and i'm even willing to pay 20$ if we can get this done. Please message me asap
I have the exact same problem. Did you ever figure it out?
Bumping an oldish thread, because this still exists. Custom recovery isn't very useful when you can't get to it without reflashing it every time.

Did you find a solution? I've been fighting my LG K20 plus metroPCS for over 2 weeks. It won't go into download mode or recovery. In recovery it skips over the reset page. I think the phone is possessed lol.
Hello guys, how are you today ?
I will do my best to write properly (french, sad)
So, i unlocked my phone with no problem. I tried to install a working TWRP. The ADB command to install was easy, but impossible to boot in twrp with the boot command on ADB.
I understood that i just needed to press up and power to open TWRP.
I putted on my OTG USB KEY the xiaomi.eu weekly ROM for my phone.
I formated only DATA, and i began the installation.
I had an error, and after my OTG was not recognize.
I just putted up and power to reboot the phone and try again.
But i dont know what happened, black screen, impossible to boot on something, i tryed to hold power 15 sec and nothing work, impossible to go to fastboot mode.
The phone is recognized on windows but nothing more.
I searched on the net and my phone is bricked. I need to open it to press ELD.
I found someone who has ELD permission for 12$.
Now i just want to know if someone can explain me how to open without damage the phone and how to be in ELD mode.
Thanks you and have a nice day.
I guess you could try to buy an EDL cable instead.
How you see phone in device manager?

Can you get into fastboot
My phone was completely stuck in black screen impossible to go on fastboot mode.
Luckely, i dont know how but my phone was recognized like if i was in EDL mode.
I contacted an asian man on WhatsApp, he putted his logs on miflash to allowed EDL flash.
My phone is Alive now!
Where Can i buy an EDL cable if i need it ? It replace the open of the phone?
Not sure how to title this forum post, but this is the best I got. Forgive my ignorance and lack of knowledge on these topics.
I was trying to root my Axon 7 mini. After some searching to find out how to unlock the bootloader (like needing JDK, older Android SDK version to run android.bat, etc.), I finally got it to work. Ran Recovery to "apply update from SD Card" (can not remember the file right now) and was then ready to load TWRP Recovery. When I rebooted to the recovery TWRP image, it told me something failed and the phone had to be factory reset. I took my SD card out in fear of my data being deleted and "accidentally" clicked the power button. It then reloaded with a password prompt where I typed some random password (1234 because I never set a pin password nor knew what to do here), clicked submit, and then gave me some error; now my phone doesn't work.
The Problem:
- I can enter bootloader, sometimes, but can only run fastboot commands; adb device does not detect phone so can't run adb commands (always says the server is old or something and reloads daemon successfully but never finds my device regardless). Also, I don't think I can get it to run in EDL mode; MiFlash gives out errors too when trying to flash recovery images.
- Recovery mode doesn't appear or work; not sure if the MiFavor command prompts on the phone is recovery or not, but it's safe to say this no longer appears. This is also where I believe the phone bootloops. I can get the fastboot commands to flash a TWRP recovery, but it never actually enters the TWRP dashboard.
- Can not turn off the phone... I think. None of the command options that appear on-phone shut it off; however, when the screen does stay black, I'm not sure if it's in EDL mode or plainly off.
- Device Manager shows the phone as different stuff (namely Kedacom USB Device and Portable Devices/MTB USB Device). Sometimes Qualcomm appears, but it depends. More often than not, when my device does appear, there's either an error code (like Code 10, Code 43) and/or the device is grayed out.
Conclusion:
I just want to get my phone to work normally again, if possible. Currently, I locked the oem to see if fastboot commands could still work and now I'm stuck at the ZTE logo, so can't try to unlock it right now. What are the proper tools, drivers, programs, etc I need to get this phone back to normal? I've scoured the web and these forums for 2 days now with no luck and lots of either missing info or obscure info.
I bought this at Best Buy, so I'm assuming it's US Axon7 Mini version in terms of drivers (not sure if the box specifies any info that could be useful here).

Dear all,
I experienced the same issue with my phone after I tried to flash it with custom ROMs and recovery.
I thought I lost it as I was not able to enter adb mode (not recognized on the PC) or even not able to enter EDL mode with the button combination so not able to do anything with it.
Only watch it boot and display the ZTE logo.
After some research, here is what I had to do to get it recovered.
First thing you need to get is an EDL cable.
I let you search on your favorite site. Mine was a Generic eDL Deep Flash Qualcomm 9008 Cable 2 in 1 for Z3 X/Octopus.
Until you receive it, make sure you have the latest Qualcomm drivers installed on your PC.
You can find it easily.
Then, connect your phone and your PC with the EDL cable.
Press the button on your EDL cable (there should be one) for a few seconds and keep it pressed.
Then, press the power button and keep it pressed for at least 20 seconds.
At this stage, you should have both buttons pressed and after some time, you should feel the phone rebooting.
After 20 seconds, release the power button.
Then, after 10 other seconds, release the EDL cable button.
At this stage, your phone screen should stay black and your phone should appear in the device manager as Qualcomm USBHUB (or somehting similar)
You are in EDL mode and should be able to perform a recovery flashing using tuliptool.
Then I followed the steps I found here:
https://forum.xda-developers.com/axon-7-mini/how-to/updating-uk-version-zte-axon-7-mini-to-t3717933
If you are still stuck, pm me.
Be patient, all will be fine,

At this stage, your phone screen should stay black and your phone should appear in the device manager as Qualcomm USBHUB (or somehting similar)
You are in EDL mode and should be able to perform a recovery flashing using tuliptool.
Then I followed the steps I found here:

Be patient, all will be fine,

I had a feeling an EDL cable was my only option left given everything I've looked up and the multiple methods I've tried. Wanted to avoid spending money on one but doesn't look like I have a choice given the circumstances - oh well. Regardless, thank you for the response and advice. Have to wait a while, though, to get the cable and test to see if this works.
If anyone else ever ends up in the same royally screwed situation as me, getting an EDL cable - or DIY one if you wanna be cheap and are confident enough to do so - is probably your saving grace.

K, I can get tuliptool to work and run command, but i keep getting a "Failed: Unkown Error" response everytime i run a command. Can't unlock my bootloader, nor write a recovery disk due to this error. does anyone have any idea why this happens?
