How to unlock bootloader and install twrp

Hi,
I currently have a lg l90 model D415 running android lollipop 5.0.2. I am rooted with super su and would appreciate is someone could give me instructions on how to unlock the bootloader and install twrp, including how to install adb or whatever driver and/or how to boot into fastboot mode, if necessary. Thank You!

Have a look at the linked threads from this post.

As far as I know, the bootloader for D415 devices is already unlocked.

I'm using a D405n version. Any advice is welcome.

The steps I found out to follow are:
1. Root with manual http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
2. Bootloader with http://forum.xda-developers.com/lg-l90/development/recovery-twrp2-7-1-0lgl90w7xxshoxx-t2826150
3. Custom recovery TWRP with http://forum.xda-developers.com/lg-l90/general/guide-guide-to-unlocking-bootloader-l90-t2852917 and instructions under 2.
4. Custom ROM with http://forum.xda-developers.com/lg-l90/development/rom-cyanogenmod-12-lg-l90-t3049512

No need to downgrade to Kitkat it seems. Anybody can confirm these steps?
thanks but can someone help me download adb. Thats the only thing i dont know how to do. Thanks

Bootloader is unlocked on that phone. .. just to confirm the previous post.
how would i confirm that? However, i already flashed the twrp 3.0.2 img with flashify and it works properly as i flashed the exposed framework zip. Does this represent that it works correctly? Will i be able to flash a custom rom too? Thanks in advance

If you were able to flash a custom recovery and it boots into it, then the bootloader was unlocked already; otherwise it'd just boot into the system or boot loop.

As for the adb, just check the L90 threads (unless I find mine before then) and wherever you unzip the adb.exe file folder to, open that folder in the explorer window, hold the shift key and choose "Open command prompt here". The adb commands will work then add long as you have the appropriate drivers installed.

Oh... and yes. From your recovery you can now flash custom ROMs. Just make sure they are for that model and the instructions are followed.

Is there any major diffrence between D405 and D410 ? I can buy new D410 a little bit cheaper than new D405., but basically I don't need dual SIM functionality.
I have read somewhere that dimensions (width) are little bit diffrent (so cases for D405 don't fit D410).
Is rest identical? In terms of everyday use, no root, changing roms etc

Yeah, cases and silicon are mostly ok, so no prob there, just pay attention when buying, however big issue are
protective glasses and foils, its quite difficult to find them for d410.

I'm on d410 v20c and I want to unlock bootloader and then install custom ROM:
I was suggested to first downgrade, becaude I can't unlock v20c.
The problem is that I can't find any reliable source for a couple of stock kdz files with aroot available here in the forum.
COuld anybody direct me?
All of the links are from 3 years ago and broken.
The only possible couple I've found so far after hours of research are with kdz 10d downloaded from external sources and I'm not sure if it's reliable
RO/Romania D41010d_00.kdzFile from https://lg-firmwares.com/lg-d410-firmwares/#more-1415
or the same from here http://lg-kdz-firmware.com/download-...10d/11866.html
