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.

I used the GAIOv1.50 toolkit (Great tool! I just obviously don't know what I'm doing) to root my LG Optimus G I also used it to unlock the bootloader but I did not use it to install the custom recovery or restore the unlock stock boot. After doing what I just mentioned I restarted my phone. I was able to access the bootloader menus, but after realizing that I didn't install the custom recovery or restore the unlock stock boot, I performed those steps from the backlight screen. Now the bootloader screen loops and I can no longer access the menus and I don't know what to do from here (Or from the beginning obviously). I am definitely a NOOB and need help.
Please help!

Did you solve the problem? How? If not, try this http://forum.xda-developers.com/showthread.php?t=2010624
I think I now understand my mistakes, but I'd love to hear it if there's a way around this. I have the International version H815. My plan was to end up with a rooted version of Marshmallow. At the beginning of the day, I was not so clear about the difference between unlocking and rooting. I followed directions to install a rooted version of Lollipop. That went well. I flashed TWRP but couldn't figure out why that didn't work until I figured out that the bootloader should have been unlocked first. I then went through most of the steps to officially unlock the phone, but my phone just hangs at a fastboot intro screen using the abd reboot bootloader command, so I can't use the fastboot utility to recover the device ID I would need to get an unlock code. And I can't get into the original recovery menu using the power-volume down keys. I think I overwrote the stock Recovery utility when I flashed TWRP from within a rooted system. Switching back to a stock kdz didn't help. The phone still works fine otherwise, but now I see no path to unlocking it and then installing TWRP to load a rooted 6.0 image. Should I just give up now, or are there any other options?
Thanks,
Jim
Got it working
I reinstalled the rooted image and flashed a stock recovery.img. That didn't work. Then I went back to stock with a different kdz image. I still couldn't access the recovery tools with the power and volume down buttons, but I was a able to get fastboot functioning and got the unlock code from LG and entered it - now to see if I can go back to an unlocked system and install TWRP to upgrade to Marshmallow.
Dear all,
I'm stuck and I don't know what to do.
I can't root my LG G3 D851 (T-Mobile) phone.
Recovery mode is only deleting the files (Original LG screen).
Purple, oneclickroot, kingroot they all fail cause they can't start in Recovery Mode.
I think that my Bootloader is blocking this, but LGUP doesn't recognize my Phone.
LG Flash no working DLL? I'm stuck and I'm starting to miss ODIN.
Is anyone able to help?
Cause I don't see it anymore
I have a variant of your phone, the LG G3 D858HK, I sort-of had the same issue and also found that KingRoot, Purple, etc failed, but Towelroot worked when I took the phone out Recovery Mode ..... after about the 10th attempt at trying to root using it that is...... Apparently it can take several attempts using the app before you obtain root

You can't unlock the bootloader. You have to downgrade to a lower version of lollipop, root with kingoroot, and run autorec.

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
Hi, i just got a LG G8 ThinQ Verizon last night and i wanted to install lineage OS for it but when im done unlocking the bootloader and installing TWRP 3.3.1.0, my phone just keep booting into TWRP and saying no OS installed, it couldn't reboot into system or fastboot or edl, is there any way to fix this?
Verizon doesn't support custom ROM, for your case, please flash the original firmware

Im trying to flash the original firmware into my phone but it cant boot into edl mode, which is needed for flashing stock rom.
dont plug your phone in usb while booting into edl, most of the case it wont work if you plugged in
if it dont work, force shutdown your phone and try EDL combo again
