Just want to thank you for the video but most of all explaining in depth of the method you used been searching for months and everything has failed me but with this video and also the files in description i was successfull, keep up the good work. Greatly appreciate the Assistance

[@358kasey]

Really glad this video helped you! I had the exact same problem as you, which is why when I FINALLY figured out how to do it, I thought I should make a video tutorial.

[@shameelkhan209]

You are a legend sir! worked perfectly for!Only problem i encoutered during whole process was...fastboot wasn't recognizing twrp...then i pressed tab after it and it worked perfectly...again sir thank you

[@surafelbeyene3883]

[@johnc5315]

great job! there's a pile of complex issues for the g4 and especially h811, and I walked right into the dreaded boot loop mess. All fixed fine for me - thanks to you and XDA forum. YMMV is certainly true. NU Lineage 14.1, Bootloader unlocked, SU permanent before TWRP, and now TWRP permanent as well... Thxs... :)

[@358kasey]

John Chester Glad I could be of help! And congrats on making it through that mess haha.

[@zipdrive]

Well done sir! The no talking (I'm guessing foreigner)'s method was not working but yours is. He's the suggested video before yours or at least what was served up. :D

I want to download Modules on Xposed and it always puts me in a bootloop then I have to factory reset and start again! Any advice?

[@louiscandell5852]

Great video!!! Thank you, I skipped the downloading the offical TWRP app and just copied the TWRP img file that we used from the fastboot, then used Flashify to flash that file :D

[@809Blanco]

OMG I had to figure this out dolo. You talked my ears off for an eternity. thanks for trying to help, If you really want to keep it simple just say the steps with little to no comment.

[@mr.disappointment]

For everyone with in fastboot: 1) Run the command prompt as admin (win+x command prompt as admin) and go to adb and fastboot folder; 2) Install the driver for the fastboot state. Not LG main driver. When you run adb reboot bootloader Windows will begin to identify the device as android in the devices list, with no driver installed. Go to Devices and Printers (win+r control /name Microsoft.DevicesAndPrinters), right click the android device, properties, enable changes, go to the driver page and manually update the driver to LG provided one (when asked to look for one online choose to select it manually from a list);

[@AhmedYar3]

Great job.. It worked for me. I tried other methods but nothing happened.. After trying your method i just did it

[@Trocker360]

omg thank you i watched so many other tutorials and by following u step by step i finally got it except for a little part i had to figure out on my own

[@358kasey]

+Tunde M Really glad I could help! Is the part you had to figure out the part where you flashed TWRP? I forgot to mention to flash it before booting from it.

[@Trocker360]

358kasey​ yea that was the part and in the progress somehow my phone got wiped so i lost everything but it doesnt really matter im good

[@luisgaldamez8686]

[@Trocker360]

[@luisgaldamez8686]

Tunde M yea I had gotten out of bootloader screen and I just had to get back in to continue

[@rooferization]

Very clear and concise instructions, My problem is the bootloader will not unlock, is there anyway to force unlock the boot loader, I have a Hannspree HSG 1297 Tablet.

[@yamahabalu]

Thx 4 ur time and appreciated. My g4 didn't take your way. But, moved the su zip file into platform-tools, After your fastboot boot twrp.img command, and in the recovery on the phone hit advanced and ADB sideload then in the PC cmd window command "adb sideload BETA-SuperSU-v2.65-20151226141550.zip" (no Quote) worked fantastic. Thanks.

There are two problems that might be occurring. The first could be that you don't have USB debugging enabled, and when you plugged in your phone to PC you didn't hit the "Trust this computer" dialogue on your phone. The second could be that you don't have your phone driver installed on your PC. Search for LG G4 driver online and you will find a download for it.
