g2 screen gets a problem... - G2 Q&A, Help & Troubleshooting

My screen gets many "line" at the edge after I flash g pro 2 lollipop ROM to stock 5.1,I can't upload photo,sorry
is it about hardware or software?and how to fix it?the a lot.

I'd like to help, but it's tough without seeing the problem. Can you maybe describe the "lines" with more detail? Are they flashing? Are they constant?

Same problem at my D802
Looks familiar? Looks like I have the same problem. After making clean install of Resurrection remix my screen went black with no image. When I tried to open download mode screen became grey and these lines appeared.

Blacks lines or go back to Stock

Hello everybody
Okay so I was able to switch to CM13 somewhat difficult indeed, and during manipulation I had thin black stripes that appeared on the right side of the screen. It's a bit annoying so I would try to remove it .
For this I tried to do a wipe everything except internal storage + reflash the ROM but it did not work they are persistent !
If you have a way to fix it tell me please..
So I would like to return to LG Stock BUT it does not work , I definitely think I'm not made for that ..
Let me explain, I installed the drivers , lg flash tools, and KDZ Europe Open D80230B
I followed this tutorial http: //forum.frandro...méthode/page-1
And I still blocking 2%.
If you have a solution that would cooooool !
Thank you in advance, good day.

Broken display after trying to install TWRP on D802 with AutoRec?!

Hi guys,
after finally getting a new screen for my D802 (whole other story) I installed it and it worked great. Next step was to update to a newer ROM and Android etc. so I wanted to try out Lineage 14.1.
I got AutoRec to install TWRP, which went fine until it rebooted. The display started showing nothing but white stripes.
Because of anti-spam reasons I can't link to external websites and I can't find any way to upload pictures so I'm cheating with the link and hope that is okay, if not please delete the link and tell me how else I can show you pictures.
PICTURES HERE imgur.com/a/VcLR3
The first two are during the "LG" boot animation, the latter two are when it has loaded up the OS (I assume).
Did I somehow destroy my new display? I've looked around and found similar problems for some obscure ROMs and such, but it was never the whole display but rather just a few lines to the side, nor was it with such a simple, everyday task like AutoRec that seems to be working for a million people.
Is there anything I might be missing?
Assuming the display actually IS broken and I replaced it again, would the current configuration kill the new one as well? Since I don't have even 1% of screen to play with I don't see myself changing anything back to stock or so.
Thank you so much for any help.
Edit: I just found this thread https://forum.xda-developers.com/showthread.php?t=2680948, do you reckon this is my problem? There are no pictures, sadly. And if yes, how on earth can I do anything with no screen?
Just reflash stock kdz

Thank you, I flashed some stock stuff and the display is working again. I would never have thought it was a software issue. Thanks!

half blue half black screen after flashing a rom

hi everyone.
i am having this wierd issue for a month or so, when i try to update RR rom.
after i flash the rom, i get the screen attached. screen seems for like 2 seconds, and goes this half black / half blue screen. screen is still responsive, i can receive calls and if i double tap anywhere, screen locks. there is no problem with screen on twrp or anything ( because sometimes after flashing the rom i dont get this screen, so i don't do anything else, except use it normally.) but today it happened without a reason, the phone was in my pocket when i took it out and saw the screen in this state.
i always flash by following the steps given. i know it is not hardware related. where is the problem? what do i need to do?
p.s. : when charging, blue part goes yellow.
thank you all, waiting for a solution

First go to recovery and check that display problem present or not if not then flash any other custom rom or reflash rr
if you are unable to go to recovery then flash stock rom via odin it will fix every software related issue
and if flashing stock rom doesn't work then it may be hardware issue
You confirmed the model # in download mode? Tried using different version of TWRP?
I am facing same problem recently, did you find any solution ?
still no solution. this problem is not hardware related since i can use it perfectly now. i tried to flash (via twrp) RR-N-v5.8.5 exactly as described in op. rom boots, i can see the home screen for a brief moment but screen goes immediately black and blue. i can receive calls, lock and wake screen, that's all. then i have to restore everything. i am currently on hexagon rom v2.5 and no issues but i like RR.
again, this problem is not hw related. i follow all the steps again and again checking everything..
any ideas?

make a clean install and try a different kernel than pre installed one

clean install worked for a day or so, until i turned off ambient dislpay and restart. then it went blue&black again.
i tried a few kernels, some bootloaders and modems (including nordic) but problem persists.
i will try to get a logcat :/
In case anyone has the same problem: reboot to safe mode, go to settings, flip cover and turn off S-View flip cover.

Unbranded screen problems.

Hello, as this phone is no longer used but I was sorry to keep it with the screen damaged, I bought a very cheap Chinese screen without Aliexpress, and the problem is that with its own roms works perfectly, but if I put a custom rom cover of another phone, does not start, stays in the initial Samsung logo and restarts. The TWRP 3 does not start either, the 2.8 if. Will it have a solution?
You changed only the screen, nothing else? Sounds like you changed the motherboard too.

The motherboard had already changed it a long time ago, with the original screen working perfectly. Now I have "Resurrection Remix V.5.7.4 MARSHMALLOW 6.0.1" and it works perfectly, but if I flash "[ROM] [C9 Pro Port] [N900X] AspireTeam C9 Pro v5.0 [18.5.18] [Aroma / Smooth / Modded] "does not start, stays in the initial Samsung logo and restarts all the time. Before changing the screen, it did not happen ...
Strange that C9 ROM doesn't start. I assume you are doing a full wipe before installing?
Sounds crazy but maybe flash the latest stock ROM, then twrp, then C9?
Ok, I'll do the test to see what happens.

Custom ROMs result in black screen

Hi all,
I'm new to the device so I'm maybe doing something wrong but I don't think so. I got the device with a terribly cracked, I flashed Pixel Experience (Android 10) as it's what I've had on my Nexus 5x, everything was working fine so I proceeded to replace the screen. I replaced it with one from Aliexpress which seems legit.
The phone then wouldn't boot, or seemed not to boot. I saw the splash screen then a black screen. The system did boot as I could see the capacative keys light up and sounds working, I just couldn't see any image on the screen. After a while trying to flash other ROMs and other TWRP versions (at this point TWRP showed up as a black screen too) I found that the following solution solved my problem.
https://forum.xda-developers.com/mi-a1/how-to/solved-mi-a1-bootloop-t3973131
This is fine, I can use the stock ROM and update it to the latest version but cannot use any AOSP based ROMS and still cannot use any other recovery apart from the one used to solve the "bootloop".
Does anyone have any idea how I can solve this? I thought the screen was maybe a weird version that needed some additional drivers but the strange thing is that it works for the stock ROM.
Regards,
Simon

I'm in the same situation. I think these screens are not 100% compatible so it seems a hardware issue.
Maybe using vendor partition but i'm so stucked as you.
My phone can't hotboot any official recovery although i can boot flashed recovery only if i boot slot a not slot b.
Stock roms boot always using slot a but tried Lineage (thats uses slot b) and got always black screen.
I'll keep reading and trying to solve it.
Regards.

Thanks for your interest but I've made no progress and actually given up on it. I'm sure the issue could be resolved by buying a new, more compatible screen but I'm not going to put any more money into the phone.
As far as the software solution goes, I've tried almost every combination of ROM + Kernel i can think of but the only thing that works is the stock ROM.
I'm going to close this thread as I don't think it's much use to anyone.
Regards
Sorry for posting here, but i am in the same and i noticed that flashing canting 4.9 kernel gives display for like 8 seconds after screen turns off. May it be a kernel config issue? if anyone in this forum could answer this i could try and change it. Also flashing stock kernel on custom rom solves the problem but makes other thing fail
Hello, I've got the same issue. Is there any solution ? Or, at least, any clue to work on it ?
EDIT: I finally done it!
with this kernel (OC) : https://forum.xda-developers.com/t/...rkernel-v3-1-nonoc-and-oc-12-11-2020.4186317/
And this rom : https://forum.xda-developers.com/t/rom-11-0-official-crdroid-7-1-tissot-13-11-2020.4195351/
I installed this kernel, cause you was saying it is probably a kernel issue, so I tried to look for most recent kernel.
And then, it worked, so I think you was right.
I can't be sure it will work with all ROM, but I think.
Hello Mi A1 friends.
So yesterday I decided to change my crack LCD screen and to my surprise the phone boots into Xiaomi Logo and then after that its just a black screen. Message and other notifcation sounds still come in which means that the phone mange to boot into home screen, just with nothing to display. At the time of changing screen, I am on stock kernel and Pixel Experience 10.
Gonna flash back to stock pie(9) rom and see how it goes from there.

Sry for reply to an old post, but how did you do it? How did you flash kernel when you can't enter twrp because of screen issues? I have exact the same problem, where stock rom works but everything else cause blank screen. Also can't boot to twrp - probably the same reason.
