Help, no root, no recovery, no download mode - G2 Q&A, Help & Troubleshooting

EDIT: This can be marked as resolved -- I used ADB to succesfully send a reboot recovery command to the phone and it worked!
Hope I don't run into any more issues down the road.

Hi guys
In short, my LG D802 International model has lost it's ability to enter DL mode, and the recovery is also missing.
It is now running Stock Lollipop (Custom version) which I installed according to instructions with no problem
However once it was installed I then realized TWRP is no longer accessible. My next step was to then go to the Play Store and download Autorec Lollipop for LG G2 D802
https://play.google.com/store/apps/details?id=b007.autorec2&hl=en
Once that was installed I tried to install the recovery, but the app was unresponsive. The author of the app then mentioned ->If you experience unresponsive button (the button flash doesn´t work) look up this post
http://forum.xda-developers.com/showpost.php?p=65698392&postcount=797
I went ahead to uninstall SuperSU using it's full cleanup and remove function. BIIIG mistake!
That's where the problems compounded, because now SuperSU is not even working and won't let me install the SU Binaries, and the app is telling me to search forums for help
Basically: No TWRP -- No Download Mode -- No Root -- Cannot install SuperSU either!
I'm now stuck with a very unstable phone that hangs and crashes every 10 minutes. I have tried to factory reset but to no avail -- I still cannot use SuperSU.
Thanks in advance

[Q]LG D802 4.4.2 TWRP Not Opening

Hello I need help about an Android app called "AutoRec". I have rooted my LG G2 D802 4.4.2 with IOroot but I did not get SU app so I downloaded one from google play called "SuperSU" and I have checked and it says my device is rooted properly. I wanted to do a EFS Backup just in case so I started searching how to flash a custom recovery image. Luckily I found AutoRec and done it as instructed. But when I enter recovery mode from my phone it shows the standard stock LG recovery instead of TWRP 2.7. But after using the app again and tapping go to recovery from the AutoRec app after finishing I could use TWRP but once rebooted, it does not enter TWRP again when I try to enter to recovery mod, instead it shows the stock recovery. Can any of you help me please? Thank you.
Solved
reboot

D802 CM13 SuperSU binary needs to be updated

Hello!
I have spent around 5-6 hours tonight fixing my phone. Before it had CM13 working just fine but my recovery didn't work (got an error when trying to enter recovery). I manged to solve that problem by doing lots of things I have already forgotten about now and to be honest I didn't really have any idea what I was doing as I am very new to this and have no knowledge about it.
Right now my CM13 works just fine. No problems booting. My recovery works just fine. I have CAF bootstack and the latest TWRP recovery that was mentioned in the guide. However, my SuperSU doesn't want to work properly. At first, I had to download the SuperSu app from Play Store. I don't know if that's how it is supposed to be. When I start the app it says "The SU binary needs to be updated. Continue?". I press Continue and it says "If you have a custom recovery like TWRP or CWM, that can be used to (try to) install the SU binary. This is recommended for HTC devices. How would you like to install the SU binary?". I have two options: "NORMAL" and "TWRP/CWM". If I press "NORMAL" it proceeds to installing and the circle is spinning and spinning... "Installing, please wait..." After about 30 seconds it says "Installation failed! Please reboot and try again". Rebooting and trying again doesn't help. If I try the TWRP/CWM option it reboots me into TWRP Recovery but nothing happens there. If I reboot system from recovery the problem remains. I googled a bit and found some thread where they said I needed to download some SuperSU zip-file and install it from recovery. I did that but that just broke it even more giving me some error saying SuperSu wasn't installed at all, or something like that. I ended up re-rooting the device and installing bootstack, CM, and GAPPS again.
I have enabled root access in the CM developer options menu, for both apps and ADB. I have downloaded Root Checker and it says i am rooted. In download mode it also says rooted.
Is there some step I have missed? Please help me. I just want CM13, Recovery, and SuperSU to all be working at the same time. Not just pick two, like I have done before.
I had the same problem on my d802. That thing you did in development settings worked for me. Is supersu so neccesary?

Zenfone 2 Laser (ZE500KL) - problem with bootloader, twrp & supersu

Hello,
recently I have flashed my ze500kl with XenonOS. I would like to go back to stock rom but I have couple problems.
First of all - my bootloader is now locked. I wanted to unlock it via SuperSU, that is already installed on my phone but when I try to open SuperSU App I see this:
"SU Binary occupied"
So I found tutorial on how to fix this issue, but the problem is i can't uninstall SuperSU, I can only disable it in App options.
Then I tried to install TWRP via App from Google Store, but offcourse my phone isn't rooted so I can only download TWRP installation files but can't initiate installation via App. I downloaded TWRP on my PC, opened ADB in CMD, installed it there and rebooted my phone. TWRP isn't loading and my device stuck on ASUS welcome screen.
I tried also WINDROID but I get lots of errors, so it's not working for me either.
Please help me unlock and root my phone. I really want to go back to stock os.
Thanks!

For anyone who struggle with the same issues.
Use ADB and twrp_2.8.7.7.img. I don't know why, I don't know how but this version of TWRP works.
