I'm having the same exact problem
Probably cyanogenmod rewrote something from TWRP. Did you try reinstall TWRP after cyanogenmod was installed?
There's a reason I don't cyanogenmod its very buggy on the g2 Mahdi ROM is the best I've had no problems with it

[Q] Note 3 can't boot into recovery

I am using CM12 nightlies on my N900W8, and I haven't had any problems until I tried to flash a new nightly (while running 20150410-NIGHTLY-hltetmo) and instead of booting into recovery I got a black screen. After taking the battery out and back in and trying again, the same thing happened. When I started it back up again the internal memory was completely wiped, I have no idea how or why. It can boot into download mode but I cannot get into recovery and therefore can't flash a new ROM or recovery to fix it. What do I do?
Download mode flash stock rom through Odin .

Didn't work. I tried CWM and TWRP, both resulted in a black screen when booting in recovery mode.

Bricked tablet? :(

Hey everyone I'm really in need of help.
I flashed cyanogenmod's v 13 rom coming from 4.4.4. In cwm it said may of lost root, yes to fix? I wanted to go back but it booted anyway. Now I'm stuck on this ROM without any Gaaps, and when I go to boot into recovery to flash the gaaps, it only shows the Google logo so CWM appears gone. I've also tried downloading playstore and ROM manager via the Web and it force closes when it goes to download.
I'm I doomed or is this fixable?

D802, flashed CM 13, black screen after <1s LG logo

I have been using CM12.1 on an LG G2 D802 and decided to upgrade the device to CM 13 today. As the device was running the stock 4.4 ROM before I initially switched to CM 12.1, I figured it would already have the Kitkat bootloader installed and proceeded to download the latest CM 13 nightly from the CM page as well the stock OpenGapps package. I then booted into TWRP (v2.6.3.3), wiped system, dalvik, data and cache and then flashed the ROM and the Gapps package which worked just fine.
However, when I selected "reboot system", the screen went black. I turned the phone off by pressing the power button. turned it on again and found that the LG logo flashes up for less than 1 second, then the screen goes black again. Gladly, I am still able to boot into TWRP. I then searched the forums, decided to try the latest Lollipop bootstack from this thread and reflashed the ROM and the Gapps package, but the problem still persits.
I am now thinking if my seriously outdated TWRP version is causing the problem, but I hesitate to update that (as it is basically the only working thing on the phone right now) without making sure that it really could be the problem.
Do you have any tips for me what could be the problem and how I can fix the phone?
Thank you very much!
Any help is appreciated

to boot into system you need hybrid bootstacks, and definitiverly need thermal twrp 2.8.7.3
you could either do both. download twrp and bootstaclks the hybrid ones.
first update twrp if you want. but i recomend as it has thermal to control heat during installations
once you in twrp. wipe all. then reboot into recovery from recovery.
flash hybrid bootstacks then again reboot into recovery from recovery, and when you in twrp flash rom it should boot.
just remeber to reboot into recovery each time you flash twrp ot hybrids to take effect.

kernel?? rom has kernel..
sometimes when you flash and no boot you need the hybrid bootstacks..
in this process... flash recovery reboot into recovery..... then flash hybrids first link i gave you.. then go back to main menu reboot/ to recovery from recovery again to take effect. then once in recovery .. flash rom and gapps.
