Installed GAPPS
Everything was working great. I think kept reading and saw that I needed to install kernel.

Try to boot to recovery with VOL DOWN+POWER...hopefully you had a backup or flash another rom

you have to time it correctly. Turn on the phone holding power and volume down. Then when the logo shows. Quickly (not too quickly) release two buttons and press them again and hold them until recovery factory reset screen appears then press two times power button to get into recovery.

Your bootloope, can you get into download mode? Try vol up and power. Then vol down to recovery....

Got a reply from the other thread:
Use this method (scroll down to where it says Master Reset with Hardware Keys). I ran into this issue a few times, and this is how I can get back into TWRP (when you follow the instructions, instead of wiping everything it boots into TWRP)
https://support.t-mobile.com/docs/DOC-7590 [start from "when LG Logo is displayed", since you can't power off]
(NB: It says T-mobile, but it works for all variants)
THIS WORKED!!!!!!!
Thanks again guys!

If the phone is on, hold power button and vol down untill it shuts off, then without letting go of power button, move finger from vol down and hold vol up (so youll now be holding vol up and power). Hold the buttons until the samsung galaxy s4 splash screen comes on (with white text before the boot screen). You should be able to boot into recovery and restore your backup.
I know restoring your backup didn't work the first time but you should try again. If you have any other roms on your sd card that you can flash from recovery, try those if the backup doesn't restore again

you are holding the power button still even after you let go of vol down correct? Does the phone restart if you hold vol down and power for about 20 seconds (without the finger moving steps)?

Ok.... so I take it your phone does restart. If your phone restarts, it should be able to boot into recovery. Play around with the timing of the recovery button presses and try to get back into recovery. Do a battery and sim card pull. Leave them out for a minute, replace them and try to boot into recovery after replacing them.
If none of that works, I would odin flash the stock firmware and start over with it. Thats just me.

Good news, i left the cellphone charging all night long, then i entered cwm, everything fine, and i restored the backup...
But still, i want the 4.3 rom, What could I have done wrong? Maybe is because i didn't root the phone after?

If you want, try re-flashing it...but your really not missing out on much (major battery drain, no root, no new features). Im not sure what went wrong but its definitely not because you didn't root it after flashing.
Good to hear you got the issue resolved though

When you hold these two buttons and you see the LG logo, release and hold them again fast until you see factory reset screen. At this point press the power key three times and you will go to recovery. An press the thanks button here.

I think you have have to hold for 5 seconds to completely power down.
Hold vol- and power key and when logo pops up release power key and again hold power key then Reset screen should display. Press power until it starts factory reset which will dump you into Recovery.

i had to get ADB on my device to root and put CM there in the first place, not sure why its not working now... maybe because USB debug isnt checked? i have no clue.
all i need are drivers right? is there a good link for re-setting that up

my adb works fine even with no rom
maybe try to reinstall the usb drivers and replug the phone
http://www.lg.com/us/support-mobile/lg-D801 scroll down and download... the driver should work fine even though its d801
try putting a rom on a usb stick and then in recovery install from usb? not sure whether that would work but its worth a try
i installed those drivers but its not recognizing device in adb

[Q] Please help! Stuck at LG Splash screen on boot

I am rooted and had PhilZ recovery installed on the vs980. I wiped data, cache, and davlik to install a new rom, but the install failed. After the install failed I realized I had deleted my backups I had. When I went to reboot the phone said it could not find root and would attempt to root on its own or something of that matter. I am now stuck on the lg spash screen with the led blinking green/blue. I cannot boot into recovery or download mode by holding the volume+power buttons the phone just vibrates and turns off for a sec then right back to the lg screen. Can someone please point me in the right direction. Thanks in advance
Yeah try booting into recovery but a little differently this time.. Turn the phone off, hold power and volume down to turn it on but keep holding it until it shuts off again. Then press power and volume down again until the LG logo appears. Release and press them again quickly like normal. This has worked for me in the past when I couldn't boot into recovery. Idk why but it did.. Give it a try

[Q] Bricked Verizon G2

I made the mistake of wiping TWRP from my phone. I did a factory reset when I booted into TWRP. I tried installing the camera app mod. I am on 4.4.2. I am currently stuck on the LG screen and the phone will not power down. I cannot boot into download mode or recovery. I have tried to research as much as I can from other threads and I cannot find any that match my issue. Do I need JTAG service to fix this?

While my phone is stuck on the LG screen (the phone will not power down) I hold the power button until it powers down, and it automatically reboots. When it reboots I hold the power button and the volume down button when the LG screen reappears and it just reboots again. Thanks for the quick reply. -Josh

Weird Problem on TWRP. Boots up with Android, but not with key combination. HELP

Hi, I have a Galaxy S4 i9505 running TWRP 3.0.2-0 jfltexx. I am having a problem where TWRP won't boot up when using the key combination of Volume UP + Home + Power, it will show up with the Galaxy S4 screen then at the top left corner it will show kernel not seandroid enforcing, recovery booting. Then it will boot to a black screen and then after 3 seconds it will vibrate and boot into android like it normally does. However on Flashify (Android App for flashing) I click the 'Reboot to Recovery' Button it boots into TWRP and it runs like a charm.
Android is running completely fine, stock 5.0.1.
Help will be appreciated.
UPDATE : SOLVED, Thanks to @QueryVillain
Solution :
1) Volume up + Power button while device is off
2) As soon as you see something in upper left corner, release both buttons and you will be booted to recovery
Try TWRP 2.87 to see if you still have the same problem.

Sorry for the late reply, but ok i'l try it out.
The actual key combo is volume up + power button. Home button is not necessary.

I flashed TWRP 2.8.7.0 and i'm having the exact same issue, just a black screen then about 3 to 5 seconds in, it will vibrate and show Galaxy S4 screen and boot to android.
Similar behaviour started to happen to me after flashing new bootloader via ODIN, but instead of booting to Android, my phone just turns off. At first I thought recovery got overwritten, but I still could boot into it from Android restart menu
What works for me:
1) Volume up + Power button while device is off
2) As soon as you see something in upper left corner, release both buttons and you will be booted to recovery

Normally, while trying to get into recovery, you hold the buttons until it vibrates and then release.
If you don't release the buttons (the power button especially), the phone will turn off at some point.
