N bootloader? Nougat
I install the 3.2 TWRP, later install 29a beta official by LG.
Now the phone is blocked in download mode. I don't send comand with adb for start recovery.

I use the STOCK ROM 0.78 ww
I'm with the unlock bootloader problem even in rom stock.

It only works if you use custom rom? Or also in stock?

The bat file it blocks before unlocking is only put in fastboot and run the file without fear.

After I used it with Lollipop droidboot ww t00j stock .78 I had problems with camera. It works only with kitkat?
@ XHook
have you worked on method to re-lock bootloader..
bricked my bootloader
After flashing this I couldn't access my fastboot. Now I can't even boot to system. I'm stuck at the USB logo, where usually I could reboot to fastboot (via pressing Power & Vol +) to fix this. But now I can't even access fastboot. When I press Power & Volume Up, it shows a battery icon. Please do help @XHook.
Editted:
Sorry for panicking back there. I forgot the reboot to recovery way using Power & Volume down. At least I can still boot to my system. I'll try to find a DIY solution for this. Sorry for panicking, @XHook.
Your tool uses Fastboot of 4.3 version right? Is that the difference?
no more update? camera not found, can this method by xhook solve the problem?
i've tried this version, but make my bootloader missing/bricked, same with ezrawk post
Note : When I installed this version >> 3.24.40.87 latest stock lollipop firmware
@XHook, tell me what your firmware version when you install this UBL method.
Thanks

I was using a custom recovery (TWRP) at that time so I flashed a fastboot via install. If you aren't using a custom recovery, you'd probably want to check this out: Zenfone 5 A500CG, Zenfone 6 A600CG Last chance to debrick (This fix youre IMEI) by swiczak
About the flashable fastboot, try searching for it in the Help & Troubleshooting part, I think the user who upload the flashable fastboot zip was tank0412. Try PM-ing him. Sorry can't help you about this 'cause I forgot where I saved mine.
Goodluck!

Did you flash the community build that oneplus offers? Not. 3.1.2 but 3.5.2? it bricks booting / flashing into twrp and therefore flashing anything else. Sideloading doesn't work on that either.
Flash the TWRP recovery attached to the first post of that thread. Then you should be able to boot into twrp and flash another rom to get your phone back to life.
http://forum.xda-developers.com/oneplus-3/how-to/how-to-dirty-flash-oxygenos-3-5-2-t3462288
Report if it helped. Good luck
Yes i did and i had the modded twrp but now it doesnt work and i am unable to flash the 3.5.2 community

Did you Find solution for this problem? My friend also has this problem, after unbrick.
Can you tell what you did before you brick your phone first time and all steps after?

1. Unlocked?
2. OEM unlock set in settings?
3. Follow the official twrp thread here on XDA for flashing (check my signature). fastboot flash will not work!

maybe the problem is when we twrp 3.0.2.0-1 i did mount system and get a full wipe and later flash stock with lgup and now can not install twrp anymore
It seems that you did not enable usb debug in Settings>General>Dev options.
If you did try another usb cable and at last try from another pc.
I also recommend Ubuntu Linux to FastBoot an Android device.

3) now i have using this. http://forum.xda-developers.com/g4/...-tmo-vzw-intl-variants-soon-root-lg-t3164765/ now see my phone rooted.
4) install flashify from play store and flash twrp.
5) downloads flashable zip v20d or v20g and supersu and flash from twrp and now I'm going to flash a custom rom based on stock.

Cant get TWRP to work.

i have gotten my G4 back from RMA now and have just unlocked the bootloader but when i flash TWRP with adb it doesn't work... Any help? It is in the same folder as the tools and even on the phone. i tried with the newest version of TWRP, maybe i should try 2.8.6.0?

So where are you stuck?
Let's go step by step:
So you have unlocked the bootloader and now you have the stock boot img for you rom patched?
Have you tried to install the patched img through adb?
Fastboot flash boot nameofimg.img
Make sure is the patched img.
Once you do that you have to go to magisk web site https://******************/ download the lastest apk.
Install remember to allow your browser to install unknown apps.
Once that happens magisk Wil tell you that it needs to install some extra things let it do it and it will reboot.
I know you said you tried it but in this guide you also get the patched boot img.

when in fastboot if you write fastboot device does it show the number I'd of your device?
Also under developer option I guess you have advance reboot turned on and USB debugging on.?

Place the boot.img in the fastboot folder file. What I had to do since I had downloaded this fastboot zip but it was two in one, forgot the name but I had to put the boot.img into the file folder of fastboot so when I open adb or whatever it will detect the boot.img file.
As Yelloman said you do have to put the img file in the Fastboot folder in order for it to transfer the img to your device.
