Black lines on the screen - G2 Q&A, Help & Troubleshooting

I messed up with my LG G2 D802 and i need help because i believe it's a software problem.
When i was installing the latest cm12.1 nightly, after trying a few other roms, i also installed, by mistake, an old jb bootloader/bootstack.
As result the phone entered in Bootloop, but not a normal bootloop, on the screen start appearing some crazy interferences and then the phone boot up, but the screen not. The phone made sounds and the touchscreen work, but the screen was black/off.
I've managed to solve the problem with an unbrick method, but now i have a huge problem: the screen, on the rigth side, from the top to the botton has 6/7 black lines. I have no idea how to solve this and if is a hardware problem ... I've read it's an kernel problem, not hardware, but don't know how to solve the problem :/

I feel your pain
Hi mate
Same thing happened to me.
Background info: I had successfully upgraded to CM12.1 , was running fine for a few days then I wanted to update my TWRP, updated the recovery and just went to check that I had OTG cable support then boom, boot loop.
It didnt just loop it just loaded loaded loaded, then the screen made some funny sounds. and then shut down. I hard reset to recovery and reinstalled CM12.1 and was able to successfully exit the loop. but damage to screen had occurred in the exact same place, and method right side of the screen.
Tried rinstalling original jellybean software from my backup. no success, and also flashing other versions of CM12.1 nothing.
After some research I saw that this is a manufacturing fault and that this occured quite often. it appears that the best solution is to buy a new screen as it is the actual hardware that is damaged in the screen digitizer. I might be wrong, and I pray that I am because I want to fix it too. in the end I just bought a new note 4 (not note 5 as i wanted SDcard storage). Phone was 2 years old and a new screen costs a fortune. But i miss my little G2 and its super fast speed and simpleness. :crying::crying:
If someone else has the solution to this problem on the forum we are all ears.

[Q] Phone Problems (Bricked*) Things I've Tried... SCREENSHOTS included

I am having a hell of a time with my phone (VS980). The only changes I have done are root the phone and the hotspot mod. I did both of these about a year ago. After the hot spot mod I have not been able to update the phone, OTAs fail, but other than that the phone has worked fine. Yesterday morning the phone froze and restarted itself. Now it just stays on the LG screen not matter what I do. I have tried to do a factory data reset by holding down the - volume and the power button and once again when the LG screen pops up but it either freezes or I get the android with a red exclamation point. I am able to access the download mode but both the TOT and KDZ method do not work. Attached are the screenshots for the problems that I am having with the factory data reset, TOT method, and KDZ method. I am not sure where to go from here... I would appreciate any advice you guys may have.

The factory data reset finally worked on the phone. I start going through the initial setup and it freezes and restarts back to the LG screen...and then I'm back to square one of not being able to get off the LG start screen. I have tried the factory data reset a few times now and each time I can get to a different point of the initial setup but it eventually freezes. One time I was able to get to the android home screen but then it froze. This phone is driving me crazy.
Driver wise I have tried the LG Verizon United Driver, I have a problem where it fails to install the LGE AndroidNet for VZW USB Modem. I uninstalled the LG united driver and then tried the ADB installer and received the following error which you can see in the attached images.

I was finally able to get the TOT method working by using my laptop instead of my desktop. My desktop OS is Windows 7 -64bit and my laptop is Windows 8.1 -64bit.
I went through the initial setup process for android but I did not enter in my Google information. I didn't enter my Google information so that my backup apps would not sync with my phone. I wanted to leave the phone as stock as possible to see if it had anymore freezing and restarting issues.
Well, within about 10 minutes the phone started freezing and restarting again; to the point where it was not able to get past the LG screen... Now I am not able to get past the LG screen at all. The phone is completely stock now, it's not rooted and its running VS98010B so I don't think it is a software issue anymore.
I put the phone in a zip lock bag and put it in between two cold packs. I waited about 15 minutes and powered it up again. It booted straight to the android homepage with no problem. The damn phone is overheating... As long as I have it on an ice pack it works fine but once I take it off it starts to freeze and reboot with 5 to 10 minutes. I would take the phone back to Verizon but I am outside of the 1 year warranty now by 1 month haha what a coincidence
I have never had as many problems with any other smartphone, when it comes to troubleshooting, as I've had with the LG G2. I miss my Galaxy Nexus:crying:.. Damn you Verizon! Bring back the Nexus line!

Note 4 black screen problem

I have been having a problem with my note 4. When ever the phone is powered down and powered back up it reboots normally. I see my lock screen and everything is fine. The problem is when the phone locks either by the power button or just by screen time out. It stays a black screen even though i can swipe my my finger and hear it being unlocked. They only way to fix it is to take the battery out and reboot it then everything is good until i lock it again. Any help would be appreciated thank you.
Sorry me again just wanted to ask another question. I rooted my note 4 after this problem started happening. I used cf-auto root so from what information i have seen im still running stock recovery justed rooted. I was wondering can i flash a Samsung software upgrade without any problems. My problem with the black screen started after an software update so i wondering if i could flash and reinstall the update to see if that fixes my problem. Once again thanks in advance for your help im just trying to save my phone and hoping its not a hardware issue.

LG G2 D801 Bootloop after flash/reboot

Hello,
I'm currently experiencing a bootloop on my phone, it gets to the resurrection remix logo screen during boot then restarts. I've tried booting into recovery and download mode. When I try to boot into recovery it loads the factory reset screen as usual but when I say yes to the reset in order to launch TWRP it just goes to the LG logo, then remix and restarts all over. I got into download mode one time since this started but since then I've made countless attempts to boot into it again and can't.
What I was doing right before this happened is, I recently completely wiped my phone, flashed stock firmware, wiped, then installed resurrection remix. Everything was going perfect, it started no problem, I went through and cleaned up some apps I didn't want etc normal setup steps then I used the power menu to boot into recovery instead of just using the hardware keys and the bootloop started.
Besides the not booting, the other major issue here is that it never stays connected to the pc via adb long enough to do any actions or flash a single file. By the time the pc sees it and adb sees it, I have roughly 2 seconds before it restarts again.
I really really really need any help I can get please ASAP as this is my mom's phone and she needs it for work in 4 hours. This issue started about four hours ago and I've been trying to fix it ever since. I feel like I have looked everywhere on here and through google but probably missed the solution. Before you ask, I'm 28 not a teenager and work in IT as a career for the last 12 years so don't get the wrong impression. She asked me to work on it because I had set it up a few months back with a lollipop version of resurrection remix and magisk, but in the last month or so she was having really poor performance and issues with settings crashing and a few other apps.
I hope you don't need any more info from me, if you do however I'll be here trying to fix it until she goes to work at least. I really could use the help and would greatly appreciate it.
Thank You

Screen turns on only in the xiaomi logo.

Hello today a screen replacement i ordered in aliexpress arrived and i did change it carefully (i did this process 2 times 1 in my phone and another in a cousin mi a1. No problems).
The thing is... after this i turn on the phone and the screen turns on but only until rom starts to load and then it comes black as if it wasn't turn on. The screen turns on also in fastboot mode but instantly shutdown when entering to recovery mode or normal boot as i said. The phone is working properly the rom loads and there is notification sounds and touch is working too.
If anyone can help me please. The only thing i can thing of is that the screen came with some strange malfunction.
EDIT: I flashed stock rom with flash_all and got the screen and everything working fine. I then tried again to flash a custom rom as i had before and screen failed to turn on again. Then i flashed stock kernel just to try if was it the cause and after this screen worked fine again but i lost wifi and probably there is other issues because of the stock kernel on a custom rom. I don't know if it may be because a different display driver or a kernel setting that may cause this malfunction. Hope someone can help me to solve this as i really want to use a custom rom.

Won't power up or boot into download/recovery after interrupted update

Please help! My S5 Neo was in a drawer for a few months after the LCD got smashed. I recently bought a new LCD assembly and connected it to make sure it worked before fitting and it was fine. However, the phone immediately started doing a software update but was interrupted after a few seconds as the battery was dead. Now the phone won't power up or boot into download mode or recovery. When I plug the phone in to its charger, the LED flashes red but nothing is displayed on the screen. I had a new battery for it and charged it in another device but still no joy. I've been messing around with old galaxy phones for a couple of years now, flashing custom ROM's etc, so I wanted to just re-flash a stock ROM into it but there's no way I know of performing this without getting the device into recovery or download mode. Does anyone have any ideas? The device is totally stock and hadn't even been rooted. I'm currently using an S4 Active running Lineage OS 17.1 so I'm not desperate for a phone, but I loved my S5 and really would like to get it up and running again. It never once had any problems.
