To everyone if I forget mention please let me know
You need to enter the different boot menus (mainly factory data reset menu and fastboot menu) many times, so I just have notes here on the top of how it should happen
- Download mode
How to enter : Device power is off, hold volume up -> insert usb cable -> should go to download mode
- Factory data reset menu
Hold Power button and volume down button when boot starts. After some seconds (when phone vibrates or LG logo is visible) let go of power button for 1 second, and then click power button. (This caused me the most headaches, as if I were holding the buttons for too long, the device would cut power and reboot)
fastboot mode
- when device is shut down and without usb cable, hold volume down button for few seconds and plug in usb cable

Read post #1 of this thread and you'll know how to root. There's even a section called "FLASH TWRP AND ROOT".
It seems like you posted without reading anything first...
If you don't understand what I write then the end of the thread have video for you to follow. If you really wanna root your device try to do some research at least a basic one.
I was following the video and it has link to file:
Rom_LGv30_V300s_v21e_Oreo_full_stock.zip
I have Android security patch level
May 1, 2018
And Software version:
V300K21g
On the video @bilong9 has March 1, 2018 security patch level and V300K21e software version. Other software info are the same. Can I use the Rom and other files on that video? Sorry for noob questions

Thanks, worked for me too! Thanks to @bilong9 s video and @ChazzMatt advice on the original thread. I pretty much followed bilongs video, but I wasn't always sure which buttons @bilong9 pressed, so I took notes of what I did to better understand what is happening (last time I rooted Android was back in the days with note 3). It might be that I did something unnecessary, but in the end I got root. (I Had Security patch level: 1 May, 2018. Future security levels might not work)
I'll leave my (quite detailed) notes here if somebody finds it useful
basically it is just text version of @bilong9 youtube video. All credit to him of the links and steps

I wanted to get rid of the korean rom bloatware (and korean text all over the place) so I DL partition flashed h930 EU Rom without xbl1, xbl2, modem, recovery and recoverybak with the patched LGUP. For some reason, I still lost recovery (maybe because I did not manage to do the button dance on first boot?). Then in Fastboot mode I reflashed TWRP, got in to twrp and rooted the phone again.
Calls and data are both working. But when booting the phone, it seems to take longer time than before to get sim signal (around 30 seconds after inserting PIN code). Also when I made my very first call, signal disappeared but came back after a reboot. It has not occured anymore. Also Lte Multiband selection engineering menu is not working, but that was kinda expected.
I kept korean xbl1 and xbl2 because I found a post by @bilong9 when he first discovered how to get signal back. I don't know if signal would work with only korean rom modem.

You can use international rom ( BoomBox). in the following order
Flash rom v300x.zip > in twrp full wipe > flash rom boombox.
I am using rom boombox 20r
fastboot's not working on my v300L

Have you followed the instructions in post #1 yet?fastboot's not working on my v300L
You can't skip ahead. You'll get fastboot commands when you follow the instructions step by step.

Hello to all. I have been following the detailed instructions by Defic based on Bilong9 and watching also video in youtube, so I have got well prepared before unlocking bootloader in my LG V30 v300k. Thanks a lot, I could unlock bootloader and installed root and TWRP, but I faced at the end with a problem of missing carrier signal. I thought maybe I have done mistake and downloaded stock and flashed it in LGUP in Refurbished mode since Bilong9 has advised to somebody with the same issue. After that I have flashed KDZ US988 since I had already bootloader unlocked, then I installed again v300k file provided in the instruction. I don't have still carrier signal. Please, help me to resolve my issue with your advises, how can I bring back carrier signal? I don't want to brick my phone, may be the issue with modem, is there possibility of installing only modem seperatetly via TWRP, will this work? What if I install firmware in LG bridge, will this work and will I loose unlocked bootloader? Thank you all in advance.
I didn't have the same problem as you.
You could try to flash the stock v300k rom with LGUP to get to the beginning state (and lose unlock and twrp) to see if you get the signal back. Get the firmware here https://lg-firmwares.com/lg-mv300k-firmwares/firmwares/ . I have not done this and I am not an expert on this subject.
Thanks Defic, I will follow your advice, though I have done it last time with stock v300k21e, mine was v300k20e.

So... I managed to get it working for awhile, then something happened...
I don't know if this will help but I installed an app called granular immersive mode and followed the instructions... then after some time my phone suddenly switched into airplane mode and when I switched airplane mode off I couldn't get a signal. So I rebooted the phone.... and still no signal. Tried to check the mobile network setting, network mode says null and couldn't search for provider, also tried the 4636 code and got into the setting found out that everything is dead, so I flashed back into stock (using LGUP refurbish), but still no signal. I, for some reason thought locking the bootloader back would help but no, it didn't help.
I'm on v300s.

- press reboot system4Thanks, worked for me too! Thanks to @bilong9 s video and @ChazzMatt advice on the original thread. I pretty much followed bilongs video, but I wasn't always sure which buttons @bilong9 pressed, so I took notes of what I did to better understand what is happening (last time I rooted Android was back in the days with note 3). It might be that I did something unnecessary, but in the end I got root. (I Had Security patch level: 1 May, 2018. Future security levels might not work)
I'll leave my (quite detailed) notes here if somebody finds it useful basically it is just text version of @bilong9 youtube video. All credit to him of the links and steps2
Read post #1 of this thread and you'll know how to root. There's even a section called "FLASH TWRP AND ROOT".
It seems like you posted without reading anything first...2Thanks, worked for me too! Thanks to @bilong9 s video and @ChazzMatt advice on the original thread.
