Can't boot to OS - G2 Q&A, Help & Troubleshooting

After flashing TWRP for D802 I can't boot into the system anymore. I can boot into recovery, but factory reset doesn't help. I can't flash other roms cos it always says 'failed' and E: Unable to open zip file. PLEASE HELP.

Try doing this to get back to stock http://forum.xda-developers.com/showthread.php?t=2432476

Just try to flash another recovery and its should be ok then.
You can't do anything but use the attached file. Run this its the :G Mobile support tool. Then run recovery and it will download your firmware and flash it again. It will get you out of the softbrick if all else has failed.

[Q] Is there any hope left for my Phone / Unbrick LG G2 D802

Hi Guys,
I had been installed a CM 10 Stable with CWM on my LG G2 (D802). I've tried to flash a stock KitKat Rom for my phone, using this tutorial:
http://www.droidviews.com/android-4-4-2-kitkat-rom-on-lg-g2-d802-install-twrp/
I was hoping, that i can easily make a backup with cwm, flash the zips and check the factory rom out. The process crashed (perhaps because I had cwm), and i was trying to reboot the phone into the recovery mode. But instead, the default factory reset gui from lg occurs and after a confirmation comes a screen with the message "boot certification verify, Secure booting error, Cause: boot certification error".
It seems, that my cwm recovery is also flashed with a new kernel. I can't get into the recovery and download-mode.
In the next step I have tried this:http://forum.xda-developers.com/showthread.php?t=2582142
and then: http://forum.xda-developers.com/showthread.php?t=2451696
The single steps passed without errors, but nothing changed.
Is there any other possibility to unbrick my phone?
Sorry for my english

Thanks for your answer, but the link won't help me. For this I need an opportunity to get into the download mode, but i can't
What do you get when power on ? Do you boot into fastboot.

[Q] HELP ME.. INSTALLED TWRP STUCK OTA, insert the code but cannot working

i have lg g2 d802, i have installed TWRP and when im updating KK via OTA it backs to twrp.
and im try this code in the link http://forum.xda-developers.com/showthread.php?t=2451696
but my phone restart and just stuck on lg logo and blinking green/blue
then i have enter download mode and want to flash KDZ,
when im running KDZ, my computer says cannt detected and in my G2 screen is firm ware update
please help me :crying::crying:
You can't take an OTA w/ a third party recovery like TWRP or PhilZ CWM Touch installed. If you can't flash the *.kdz or *.tot file from download mode, then you'll need to revert to this method...
[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2
http://forum.xda-developers.com/showthread.php?t=2582142
If you can get into recovery, then you can just flash another ROM or restore a nandroid. If you don't have a ROM on the internal SD, then you can use ADB to push a ROM to the SD while in recovery.
i can enter TWRP, and i can enter factory reset. then what should i do?i dont have a rom in my internal storage
i can enter download mode and i can enter TWRP. but i dont understand... sorryy im totally newbie.
thanks for your help btw
Flash back to stock and don't touch anything. http://forum.xda-developers.com/showthread.php?t=2432476
All you need to do is SEARCH and you will find what you have to do in order to get the phone to boot up again.

Unable to boot into twrp recovery after installing cm13 on t-mobile d801

I got cm 13 running on my d801 g2 the other day and I'm not a fan of it so I'm planning on flashing to cloudy g2 2.2 but now i am unable to boot into twrp. I enabled root, installed twrp and even enabled advanced reboot to boot directly into recovery but i keep getting secure booting error Cause: boot certification error which is what i was getting on stock android before getting cm13, i fixed the issue before with the kitkat auto rec app but I've read that auto rec can cause a hard brick if used in marshmallow. Trying to get into twrp through twrp, cm advanced reboot, hard key(power and vol down) recovery, flashify and adb reboot recovery command all cause the same error message. Any advice? I tried flashing twrp 3.0.0.4 and that put me into fastboot as does any other twrp version I've tried in flashify

It will give me the download mode message then goes to a black screen. My computer brings up 15 disc partitions with only one partition containing data, one folder called image with files include adsp, cmnlib, mc_v2, modem, playread, wcnss and widevine they all have duplicates with different file types b00-b26 and mdt .
