So today I unlocked the bootloader on my H870, and installed the official TWRP. I tried to flash Fulmics and Magisk but it didn't work and since i did a full wipe i had no OS to boot back into. I found this (https://forum.xda-developers.com/showpost.php?p=73033268&postcount=206) and flashed the .img. Now I can't boot back into TWRP and access the bootloader. Any suggestions?
Can you enter download mode? If you can try restoring firmware with the recuperation tool from failed update in lg bridge or flashing .kdz with LG UP + UPPERCUT

I have download mode and have tried LG flasher before I used fastboot to patch, It says I have wrong device model, I put in a d800 fw while it says my phone is d801 and it is really d800 (at&t)
Please I really need help
Unclear of phone history.
Phone model: D803 Canadian
Current issue:
Can NOT go to download mode.
CAN go to TWRP mode ver 2.8.4.0 installed by pressing VOL + and VOL - and Power button, all 3!. Shows some chineese characters first before going into TWRP.
I am NOT able to flash custom roms (tried cm12-d803, aicp-kk-d803) I get assert failed: run_program("/system/bin/loki.s h") == 0
I have tried the instructions here http://forum.xda-developers.com/showthread.php?t=2620733 [[SOLUTION] LG G2 VS98012b Problems With Loki (loki.sh) + [ROM][UNOFFICIAL]CM10.2], but no go..
How can I fix this?

Did you tryed to cleanflash? Btw why is your download mode missing
It shows chinese characters before going to twrp. I don't get it why it is like that
Does it show the chinese characters and then boots into twrp? If so maybe try to flash also later 2.8.4.0 recovery from blastagator.
Try to google the right rom for the D803 Canadian version cause I've read that some D803 models need to flash roms from another model instead.

I have tried couple of D803 roms, CM12, AICP KK.. they fail with the assert error for loki.
How to fix this. I am on 2.8.4.0 TWRP version.

Well maybe outdated loki or yeah I can't tell you the truth exactly, Ehhm... Maybe you have to flash the bootloader files again? Try to find bootloader files for your phone in a flashable zip. Maybe that works
First try to find alternative things before what I said about the bootloader, cause flashing the wrong things can harm it.

FIXED!
I borked it further by trying to install older recovery using dd command while in TWRP. Ended up with secure boot error ONLY when I try to press all three buttons, and then I get QDLOAD_BULK in device manager. Device continues to boot normally if I press the power button.
Tried to use http://forum.xda-developers.com/showthread.php?t=2582142 [FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2, but wouldn't work in Ubuntu. Drives kept disappearing after showing up momentarily. NOT the case in Windows. So used http://forum.xda-developers.com/lg-g2/general/unbrick-lg-g2-qhsusbbulkqualcomm-9006-t2939627 Windows application, and selected D802, it failed on a few items, but gave me download mode and Security Error on normal boot.
Used LG Flash tool KDZ flasher to flash v20 Rogers, but failed at 40%. Tried again, still failed.
Used LG TOT Flash tool, and was successful!
@SaHiLzZ Nice that you fixed your problem on your own:good: Have fun further with it:laugh:

How exactly did you fix that with LG PC Suite? I've been facing the same problem - No Download mode while I'm completely stock.
I can give you the laf.img file from the AutoRec, or you can do it yourself, use 7zip to extract the APK file then reflash laf.img, it will get you into download mode.
DON'T boot /system or you may very well lose your entire internal memory as I'm not sure if this damages the loki'd bootloader. In that case you'll have to manually boot a TWRP recovery.img to reflash your ROM.
I've got a T-Mobile D801 and tried flashing to the stock lollipop rom D80130b_00 using TWRP and the instructions on this page, but the flash must have failed. I did a full factory reset back to stock 4.4.3 prior to attempting this flash and I'm not sure what (if anything) I did wrong for the flash to fail. I can boot in factory reset mode and select clear everything, but then I just see the android guy with gears turning for 2 seconds and the phone reboots again.
Now I'm in a bootloop where I get an "error: Boot certification verify" above the T-Mobile startup logo followed by a "Demigod Crash Handler: Critical Error!" screen that provides options for rebooting (volume down) or putting the phone into download mode (volume up). After using the volume up the screen displays "Volume Up is pressed: Jump to Dload mode" and after connecting via USB appears in device manager as "LGE AndroidNet USB Serial Port (COM41)". I can't (1) boot directly into download mode or (2) get back into TWRP.
I've tried both the KDZ and TOT methods listed in this thread and neither are working. The LG Flash Tool 2014 / KDZ option starts the LG Mobile Support Tool, but it fails every time once "S/W Upgrade is in progress" reaches 4% with a generic "Upgrade stopped due to an error" message.
The TOT method fails every time with a "Model Information Check FAIL!" message. The full text is - "PID: NULL, IMEI: NULL, Model: , DLL:801, BIN: BIN_LGD801AT-01-V10c-310-260-AUG-13-2013+0.tot , SWV: , SWOV: , Model Information Check FAIL! , 00000000"
I've also tried using srktool to repair fastboot, but it gets stuck at "waiting for device".
What do I try next?
Finally got back into 4.2.2 using tot method. LG Mobile Support Tool doesn't think updates are available though??
same situation lg g2 d802

Yes, I *think* what happened was that my 30b bootstack was flashed successfully via twrp, but then the actual kdz flash of D80130b_00 failed. I had a lot of trouble at this point - needed to fix qhsusb_bulk problems first, then use the more aggressive TOT flash method to reset to stock 4.2.2.
Finally the LG Mobile Tool was still reading it as having D80130b_00 / lollipop after going back to 4.2.2 via TOT (?). Last step was to do a full restore from the LG Mobile Support Tool (options -> upgrade recovery) and it actually downloaded / flashed D80130b_00 so everything is working well now :good:
If it helps anyone I used the LG backup tool to restore apps / media and have to say that for a stock solution it's pretty solid.
qhsusb_bulk?

you said your g2 was detected as a lge androidnet in device manager but not as a qhsusb_bulk...then what problems have you fixed about qhususb_bulk? and what is the more aggressive tot method different from this threadhttp://forum.xda-developers.com/showthread.php?t=2432476
Were you able to find a solution? I'm in the same situation. Please help!
