I managed to get TWRP installed and flashed my V300L to H930 from the instructions in:
https://forum.xda-developers.com/lg-v30/how-to/korean-variant-bootloader-unlock-root-t3804505
TWRP was accessible via the reset menu.
However when I then decided to install the pixel experience rom into my phone I only had a black screen with prompts only showing by pressing the power or volume buttons so I flashed the V300L pie kdz back via LGUP.
After the flash, all seemed normal until I tried setting up google pay, it needed the bootloader locked or hidden by magisk so i tried to do both. Developer options say that the bootloader is still unlocked and I get the boot warning.
Problem is now my phone is unable to enter the fastboot menu and recovery. Trying to enter TWRP via the reset method just leads to resetting my phone, using "adb reboot recovery" reboots the phone to the dead android mascot and "no command".
Using the power down + plug in usb to enter fastboot just boots to a battery charging icon like you would see if your battery ran out and you plugged it into power. Using "adb reboot bootloader" just reboots the phone as per normal.
Download mode is working normally, I'm still able to use LGUP.
The phone works completely fine outside of these issues and not being able to use google pay (are my banking apps supposed to be working?). Is there anything I can do to bring back my fastboot menu / recovery?
v300 dont have fastboot mode . so to get twrp and fastboot mode, flash abl ,cmnlib, cmnlib64 files from h930 kdz through lg up and partition download option.
As mobile reboots after 80%, keep pressing volume down button, enter fastboot mode and flash twrp recovery ad magisk and other files.
BACKUP your data in PC before this, because you will have to format data after installing TWRP recovery

Edit:
Problem solved - phone recovered, and rooted successfully. I think the problem was that I didn't use the most recent version of SuperSU. I was using version 2.46 iirc, but I finally got the root working with version 2.76 (filename UPDATE-SuperSU-v2.76-20160630161323). The TWRP version I used is twrp-3.0.2.0-0-h960a.img. (I used this version of twrp both in the failed root attempt as well as the successful one). After I attempted root with 2.46, the phone just hung at the "your device software can't be checked for corruption". To get my phone back, I booted it and connected to USB (you might have to enter fastboot by holding the down volume button and plugging in the USB cable, keeping the down volume pressed until the phone boots, or you might just boot the phone normally and plug it into the USB cable, even though the phone will "hang" doing this, lgup can detect it and you'll be able to "refurbish" with marshmallow kdz which you should have on your computer. I updated my phone to marshmallow before attempting the root, so I had the kdz already. The one I used is v20a. Anyway, after refurbishing, the phone is recovered and usable again, you still get the "can't check for corruption" screen on boot but it only stays for 5 seconds, and then the phone starts. This is normal for an unlocked bootloader. What I did after recovering the phone was to save SuperSU 2.76 (again, filename is UPDATE-SuperSU-v2.76-20160630161323) onto my phone's SD card. Then I reflashed twrp (boot into fastboot, then from console window "fastboot flash recovery twrp-3.0.2.0-0-h960a.img". Then I had to disconnect from the USB cable, and remove the battery. Apparently some phones will perform a factory reset if you attempt a reboot via the console after installing twrp - this is why I removed the battery - then I put the battery back in and booted into recovery mode. To do this (contrary to most instructions I found online which give the wrong button presses), I held the down volume arrow, and then pressed power until the LG logo showed up. Keeping the down volume pressed, I released only the power button, then tapped the power button until I got to a recovery screen (again, keeping the down volume pressed this whole time). Select "yes" both times and you should be in TWRP. Just follow instructions from there that you can find in rooting guides. When you're ready to restart the phone, you'll get the familiar "can't check for corruption" nag screen, but this will go away after a few seconds - LG logo will briefly appear, then disappear and back to that stupid nag screen. But after a few more seconds, the phone starts up. Confirmed rooted with rootchecker!
Below is my original thread where I describe the problem
So I unlocked bootloader, installed twrp and everything fine so far. I put supersu zip file into download folder, flashed with twrp, cleared cache, and went to system reboot - now the phone just hangs at "your device software can't be checked for corruption"
I should say that instead of pushing the supersu zip to sd card, I just saved it in 'downloads' folder of the phone. I also had to do the trick where I flash twrp, and then remove battery, restart phone to recovery mode, because a reboot of the phone would not allow me to use twrp (it just did factory reset)
I can get back into twrp via recovery boot via down volume + power, and I can get into fastboot via down volume + USB cable, but I can't get anywhere else.
I installed stock recovery image from here: droidviews. com/install-stock-recovery-on-lg-v10-using-fastboot/
Went into recovery boot, the android icon shows up and starts to work, but then goes right back to "your device software can't be checked for corruption"
How can I recover this phone? It's H960A
edit:
Ok, so lgup was not recognizing it, and I couldn't install kdz to recover android. I installed lgbridge, then plugged phone in via fastboot (down arrow + usb). lgup then recognized it, and I refurbished with mm kdz. Seems ok now, but still not rooted, and I still get the "your device software can't be checked for corruption" when I boot up (afaik this is because bootloader is unlocked). Tried to root again, same issue. Except this time lgup would not recognize from fastboot, so I just booted phone normally and connected via USB. Then lgup recognized it and I was able to refurbish again
How can I root this thing? at least I have a working phone again
i got a new phone and updated into mm
i installed the drivers an everything to go
i boot the phone into flashboot mode
i flash the twrp, fastboot flash recovery blablabla.img (using the latest i downloaded from the page)
i try to enter to the twrp and the phone ignores me, it goes straight to normal boot, i cant even seem to be able to enter to recovery
the phone has unlocked bootloader, drivers updated and installed, usb debugging on, oem unlock, etc
its an E2306, with marshmallow android, the customized US 6.0.1
any ideas of what iam missing or new keys to enter into recovery mode?

if everything is Ok, You Power Off Your Device and Press Power with Volume - When Vibrated Release it.

Hi all!!
I have a Lanix ilium x200, which is a legacy device running 4.4.4. I rooted it with iRoot, and I followed an online tutorial I found to try to get twrp. It told me to download an unofficial flashify by Christian Göllner and flash twrp.img as a boot image. I did that, but halfway, I realized that didn't make a lot of sense, so I stopped it, killed the app, then flashed it as a recovery. Then, I didn't think much about it until my phone ran out of battery.
I tried to boot system, and it flashes white for a second, then nothing. Same thing with recovery (If I press volume up + volume down + power button, it gives me the option to boot system of recovery). I tried executing fastboot commands in the vol up + vol down + pwr mode (I can't tell if it's bootloader or fastboot mode or even either of then), but it isn't listed in fastboot devices, and it quickly (attempts) to boot into system. I tried using SP flash tool to flash stock recovery and boot.img, but it won't detect the device either. The phone just shows the battery charging indicator (even if I try booting it, it just flashes white and goes back to the battery indicator), and SP flash tool doesn't detect a thing (yes, I tried installing the drivers). Does anyone have an idea on how this can be fixed?
Thanks!!
TL;DR rooted and flashed twrp.img as boot image and as recovery in flashify. Cannot boot system or recovery. Not detected by SP Flash tool

Got any advice to say?
[SOLVED]
Nevermind. I fixed it myself. Turns out I didn't install the correct drivers for SP Flash tool. This time, it detected my device and flashed to my phone perfectly. I'm now running stock 4.4.4 without any problems.
After flashing ROM and then installing gapps (aroma) my phone automatically rebooted to TWRP again before complete installing gapps and now my phone can't turn it off just keep rebooted to TWRP can't run to fastboot also my phone storage was not detected in desktop using USB cable when in TWRP. tried some dd misc command in TWRP Terminal didn't work. any idea how to fix this?
I have an stock android backup and tried to restore and still didn't work always boot to TWRP when rebooted system/bootloader even power off
I tried to run fastboot in TWRP by holding pow+vol+usb cable didn't work, luckly my phone battery runs out so its forced to shutting down, so i charge my phone then i can run fastboot mode hmmm this problem looks weird in fastboot i tried to replace TWRP and run TWRP then restore my backup and my phone working again not looping in TWRP
I'm having the same issue, you resolved it by letting the battery die?

Did you ever figure this out?
Yes I ended up holding the power button down+vol sequence to get back to fastboot mode then loading TWRP via ADB again.
Hi, so I flashed TWRP recovery and booted into it immediately. However, I forgot to flash the lazyflasher zip and rebooted straight away. Now the device is stuck at the logo and I can't seem to get to fastboot or recovery mode using the command line. I read a few other threads similar to my issue but apparently, they could access fastboot mode and I can't. Am I missing something?

Have you tried pressing Volume plus + power button to boot into recovery or Volume minus + power button to boot into fastboot mode?
Solution
It also happened to me but I booted into twrp and flashed an custom rom and also the lazy flasher.zip after couple of minutes it booted up. It may help you
