[LG Optimus L90] TRBiteMyFury:
I will be explaining eeverything that happened. If you don't want to read it and just skip to the information about my phone, then please do so.

Ok, so to start with, I first bricked my phone by trying to unlock my bootloader and flashing TWRP recovery. Luckily I backed up my recovery and kernel images using Flashify, before my first brick. I then followed this to unbrick it http://xdaforums.com/showpost.php?p=61808443&postcount=9. After, I was able to unlock the bootloader and flash TWRP recvoery, following http://xdaforums.com/lg-l90/general/guide-unlock-bootloader-flash-custom-t2839690. I used the D405n v20a version of the aboot.bin file and TWRP_2 (I forgot which version). I was trying to unlock the PIE security, because when I used qpyplus 2.7 (python) and typed "python", I got an error. This is my thread http://xdaforums.com/subscription.php?do=viewsubscription&folderid=all. I tried a few times to follow multiple tutorials, which each time, I had to reflash the stock ROM after bricking it, and following the first tutorial I linked to unbrick my phone. I would get an error, saying the version is wrong, or something like that, every time I rebooted my phone. I rooted my phone again, then tried to follow the unlock bootloader and flash TWRP, following this tutorial http://xdaforums.com/lg-l90/general/guide-unlock-bootloader-flash-custom-t2839690. Using the same aboot.bin and TWRP.img I used before. It was no longer working. When I went from the very start refollowing this http://xdaforums.com/showpost.php?p=61808443&postcount=9, stupidly I tried reflashing the recovery.img instead of the loader.img. Now, my phone never acts like it did when I was bricking it before. It never shows up in My Computer, doesn't show up in drive manager, showing no partitions, when I go to device manager, under "Other devices", my phone is "QHSUSB_BULK" http://i.imgur.com/QP4fRVp.png. In properties, this is under "general" http://i.imgur.com/CVgbAFR.png. "driver" http://i.imgur.com/38HRDib.png. "details" http://i.imgur.com/ejch5sW.png. "events" http://i.imgur.com/XP3Y3TP.png. I've plugged it into different ports, I commonly have it in COM-3. Upon looking around for "bricked phone QHSUSB_BULK", I found this forum http://androidforums.com/threads/hard-brick-lg-g2-qhsusb_bulk-but-no-partitions-detected.934856/. I scrolled down and saw to install some drivers, so I intsalled them. The phone then came under "Ports (COM & LPT)" as "Qualcomm HS-USB QDLoader 9008 (COM3)".
