Black screen after lg logo - G3 Q&A, Help & Troubleshooting

D851 here, When ever i switched from cloudy 2.5 to blisspop 4.0 and after wiping everything i flashed a various of radios bootstacks and etc to make it boot after many failed attempts to boot ( it boots up but after 4 or so seconds after the lg logo the screen turns black and doesnt turn back on until after i pull out the battery) it worked after i flashed the rom WITHOUT a custom kernel so naturally i booted up just fine and thought maybe now i set up everything on my phone and tweaks i should go back and flash a custom kernel i used to use (777 r16) but then it gave me the problem i faced before the black screen after the lg logo no kernal would work. THEN another problem arised similar to the freezing on the black screen randomly during a usage thru my day the phones screen would be unresponsive animations but touch wouldnt work and i know its not my screen cause when i flash back to cloudy it works fine the freezing happens at least every 5 mins. someone halp?
also this happens on any aosp rom

Trouble Installing CM-11 Remix

Hey guys I'm having trouble installing CM-Remix 11. The rom is amazing, I installed an older version and it worked amazingly, but after I turned it off and turned it back on (I simply had it sleep for 3 days, never turned it off) the screen would go black after a couple seconds in the boot screen. The phone is not turned off, 'cause the LED light still flashes when charging and it vibrates when holding the power button.
I tried installing the newer versions, but now the ROM wont even install. It goes black on the boot screen like before. I've tried factory resetting, formatting the entire phone and sideloading the ROM but nothing works. When using the ROM it was super smooth and had awesome features so I'd love to be able to use this ROM. I have been able to install other ROMs, regardless if they are 4.4.x or 4.3.x.
Any suggestions?

soft brick problems

d851 when ever i flash an aosp or cm12 rom basically anything not lg stock and also flash a kernal at anytime b4 or after the boot it prompts the lg logo but after a while the screen goes black and it wont turn on unless i pull out the battery i let it sit in this black state for 2 hours and nothing changed not even my battery this never happened on stock and im flashing correctly. is there some new step i have to take while flashing cm12 roms? like a differnt modeam or something because 2 months ago when i was on bliss pop i would just flash after wiping and itll boot up just fine.

Sleep/Wake problems [SOLVED]

So i was using Darthstalker v3 and arter97 kernel 9.3 with no issues.
Suddenly one day, i noticed screen flicker when waking the device, followed by hesitation. So my first step was to wipe the dalvik/cache. That apparently did not help.
I then lost my bootup logos, as well as shut down, along with the screen pretty much refusing to come on.
I used smart switch to emergency recover the stock firmware. Nothing. Then i Odined a stock untouched rom. No change. Once i actually got the phone to render the screen in recovery, so i wiped everything three times, and and flashed darthstalker v6. I also rooted the phone again just before that. I
So when the phone is powered off, the battery icon is present, and the screen wakes to that no problem. Since i set the device to never timeout while charging,
when i plug it in, the screen comes on, but as soon as i try to touch it, poof, the rendering of the screen goes. But, while this occurs, i can hear the icons being pressed,
etc. Completely stumped as to what to do. Can someone help?
[SOLVED]
strangely enough, I found a solution in a most peculiar way.
I managed to finally get into the phone by charging to 100 percent. Then, I downloaded flashify, and attempted to flash tekxodus rom, as well as selecting dalvik and cache wipe.
The flash did not work. the phone just rebooted. Then, I downloaded rom manager premium, and then rom manager attempted its prerequisite attempt to detect my recovery. (up until that point, I had twrp installed).
The detection lingered, so I pressed the back key and selected reboot into recovery. Surprisingly enough, I was back in Stock recovery.
So apparently the solution to the anomaly I encountered in the OP, is to either follow the simple steps above, or, to flash stock recovery in Odin. If that is at all possible for the user. I can confirm the above worked for me as I tried everything for the last week and this was the only method that worked.
The shutdown/startup logos are back, with no screen flicker or hesitation on sleep/wake.

yeah i just suddenly started having this problem. my phone would reboot itself and then it would be updating apps as if i just flashed xposed or something, my phone would have issues with wifi, flickering lockscreen, and if you rub the screen while its off which wouldl show you information stream doesnt work either. Decided to dump the rom. Am going with the TEKXodus N5 with arter kernel

It's just like I told you. When I read that you had experienced the same precursors that I came across with the rom, I had a hunch you would be soon after posting the exact issues that I eventually ran into.
So when you download Tekxodus and flash, please keep me informed as to if it resolves the issue. As you are aware, stock firmware has not resolved the problem for me, but then again devices vary.
So enjoy the fix if you ever run into the above issue.
Im fine with stock, but I miss the fun of trying new roms.

Issue after flashing 10g Stock - Black Screen

Hi guys. I have a factory refurbished AT&T E980 that had stock 4.2.2 on it when I got it. Assuming it was the last OTA that was pushed out. I attempted to downgrade to 10g because I was still learning the recovery options for this phone. I've since flashed most of the available JB builds with similiar results. From off, the phone will show the AT&T logo for a few seconds, then go to a black screen for several seconds. Then I have to hit the power button twice to bring up the home screen. There is no boot animation, but you can hear the accompanying sound. I seemingly cannot get any roms to boot, other than stock, as they all hang at a black screen, even after wiping/factory reset. I also cannot get any variants of recoveries to work, other than the CWM packaged with GPro Recovery. The TWRP included with that only shows a black screen with the back and menu buttons lit up, and the home button cycling through colors.
I've searched through the forums and haven't seen anyone experiencing this issue. My only clue to the problem is reading something about another LG phone that, once refurbished, came with updated display drivers that caused a similar issue. Here.
Any insight would be appreciated.
*Edit
I flashed SphinX Pro v2.0 after posting this. It corrected the above issues, and allowed me to boot into the included philz recovery with no problems. I then tried to use philz to flash the Cloudy TWRP in preparation for installing Super Mini V6.5 but was unsuccessful. What I assume is supposed to be recovery is now a black screen. The bootanimation is gone, but I no longer have to cycle the power button to show the home screen once it boots all the way up.

Unable to boot roms.

Hello,
First time posting
I have a major problem with my G2, every single rom I have tried except for stock ones do not boot at all.
I have TWRP 2.8.5.0...(I think...) installed on my device and it boots into TWRP just fine. So I push over a rom file of any sort. Install it, and no problems in the terminal. I go to reboot and the device will go to the LG logo and then quickly go to a black screen. I can reboot the phone and the same thing happens every time and with every rom I can find for the device. The backlight on the phone does stay on while the phone goes to the dark screen. And a few oddities have happened when it goes to the black screen. 1. When plugged into my Linux machine the black screen will flash in a regular pattern until rebooted. And 2. When plugged into my Windows machine it will mount dozens of partitions and drives for some bizzare reason. If anyone can help thanks a ton. If you need anymore info just contact me.
same for me i tried a lot of custom roms but no one of them worked i could manage to make my phone back to stock but couldnt flash any costom one.
LG G2 LS980
Same here
