Default [GUIDE] Hard Brick Recovery LG G2

So this a guide so that you dont have to waste 10+ hours searching threads upon threads of info to find what you need to unbrick your lg g2. This guide will use multiple references and will go through every step that i had to do unbrick my lg g2 d800.

I am not responsible for making your phone worse of than it was or somehow permanently bricking your device, i am simply providing an instruction manual that worked for my situation.

Initial Symptoms:
1. Stuck in boot loop
2. will not go into download or recovery mode
3. when turning on the lg logo appears and then the screen becomes black but is still on
4. when plugging into computer 15ish hardrives try to mount and say they need formatting
5. LG detected as qhsusb_bulk in device manage

Fix:
follow this guide by @Partager.info
http://forum.xda-developers.com/show...php?p=48765620
i recommend just installing ubuntu because it reduces errors and is faster.

After this you will more than likely have recovery and can move on restore your rom or stock image if you have download mode or twrp is working properly.

If, however, you get stuck into fastboot loop and the symptoms are:
1. will not boot
2. can get into twrp using recovery but twrp doesnt work properly
3. says when booting
fastboot mode started
udc_start()
reset
portcharge
4. wont go into download mode but for a second and goes back out of it

Fix:

kudos to @cms88168 for this fix, i will use his guide but will make some tweaks.

http://forum.xda-developers.com/show....php?t=2477595

Make sure to download your versions aboot, boot, dbi, laf, misc, modem, persist, recovery, rpm, sbl1, and tz images here

and download his 7Z file and place all of the images into the extracted file, replacing his laf.img with yours.

next you want to hold shift and right click and open command prompt in the fastboot folder.

make sure your phone is connected and is in fastboot mode.

next we will be erasing and flashing all of the images back. do this one line at a time obviously.

Code:
fastboot erase aboot
fastboot flash aboot aboot.img
fastboot erase boot
fastboot flash boot boot.img
fastboot erase dbi
fastboot flash dbi dbi.img
fastboot erase laf
fastboot flash laf laf.img
fastboot erase misc
fastboot flash misc misc.img
fastboot erase modem
fastboot flash modem modem.img
fastboot erase persist
fastboot flash persist persist.img
fastboot erase recovery
fastboot flash recovery recovery.img
fastboot erase rpm
fastboot flash rpm rpm.img
fastboot erase sbl1
fastboot flash sbl1 sbl1.img
fastboot erase tz
fastboot flash tz tz.img

fastboot reboot
you should then reboot and turn your phone off. Next plug it in holding the volume+ button and boot into download mode (it should work now) if not you might not have downloaded the right versions for your phone or something else is completely wrong and i dont know how to fix it.

Next you should revert to stock using this guide.

I hope this helps some people! Feel free to ask questions or provide some feedback, this is my first guide.

Unfortunately this just happened to me too!

Followed the first guide in Ubuntu and the phone is not responsive now, which made it even worse. When I plug it back, there are no longer 15 disks. When I check the /dev/sdk (my phone in in k), there are only sdk5 8 6 15 available. no 2.

Now totally bricked
