I made a mistake last night, flashing a rom.

It stayed in the LG logo for a really long time and during boot time the colors got all distorted and I got a couple of lines!

I panicked, refreshed the same rom (in the correct way this time) and the phone booted normally. No lines.

I'm not sure if I experimented a pre-line thing or if it was just a boot error cause I tried to flash a loki-d kernel with a non loki bootloader lol.

Anyways, running aosp for the first time on this phone @_@

So nice
[G2 General] MBurns2:
pls, which rom did you flash ?
[G2 General] drivenby:
Cr Droid for the vs980 but it wasn't the rom, I think.

I tried using the KK bootloader and RenderKernel-LP_vs980-bumped-R7 for lollipop and that caused the issue.

When I went back to the old bootloader, it worked fine with the old kernel.

Anyways I don't have any blacklines atm, it just showed that one time it got stuck at the LG logo . It's been over 24 hours and at least 3 intentional reboots.

Encountered this problem a few days ago: http://xdaforums.com/showpost.php?p=57866498&postcount=421

I had 4 vertical lines on my screen. I am trying stuck pixel tool right now, it has been running for about half an hour, swapping RGB pixels, and two out of four lines have disappeared! I cannot believe my eyes, as I thought that this is a hardware issue!

Fingers crossed for the rest two lines! :fingers-crossed: I will let you know what happens, I will also post pictures later.
[G2 General] appileh:
If its not helping use StuckPixeltool. I think this can fix your lines. I ordered a new LG G3 and giving the LG G2 to my family.
[G2 General] Zarrick19:
Baah, this really should't happen to a flag ship (even though a previous generation one)... I've just bough my G2 today, brand new, 2 years of warranty, 1.1 on the box, phone itself manufactured 18.11.2014. Until everything get's sorted out, I'm definitely not going to flash anything into it. I've just rooted it a few moments ago, been in the stock recovery and luckily haven't got any lines (unlike autoprime, god bless you, poor soldier).

Like if it wasn't enough with my G Pad 8.3, which had the famous Blue Line. Luckily the panel got replaced by RMA, the Blue Line is gone, BUT WAIT! Now I've got a dead pixel in the middle of the screen. I mean, really? What's wrong with LG? I hope my G Pad has a LGD panel and the LGD panels are the faulty ones, then I REALLY HOPE I've got a JDI panel in my G2. Ahhh, this shouldn't have happen.
[G2 General] appileh:
LG is crap.. I wouldnt buy it! But LG Netherlands told me that the G3 not having the problems that the G2 have. So i bought it, but i anything goes wrong i will give them a uppercut!! I like the G2/G3 UI and the options.. But the Screen omg what a failure!!!
[G2 General] x3m.zone:
From what I've seen & read, almost all screen issues (lines) are related to KK bootloader.

Since the LG bootloaders are closed-source, and no one really knows what are the differences betwen them, i think it would be better to stick with JB bootloader. This will prevent much of the problems and will also maintain compatibility with both Loki and Bump.

Just to be on the latest version, without really knowing what that means to your phone, not worth the risk.
[G2 General] siggey:
Probably you read wrong because paranoid android use jb bootloader and most screen problems happens with pa. Never heard of screen problems on stock kk bootloader and rom. On non stock firmware (except bumped) you must downgrade bootloader to jb to unlock it using autorec.

Manufactured in November of 2014... That's pretty new, so I doubt you'll have any issues. Flash away, you're covered by warranty anyway!

---------- Post added at 11:36 AM ---------- Previous post was at 11:35 AM ----------

So I guess those people who used AutoRec to downgrade to JB bootloader and got the lines... didn't really downgrade to JB bootloader. They must have managed to flash custom stuff on the KK bootloader before bump even was a thing. Yeah, right.

Don't build a conclusion unless you know all the infos.

Black lines could be entire rows of stuck pixels. They're hardware alright!

It's not 100% LG's fault that we got lines because we are also the users who are flashing and we don't even know the real cause yet.

I am still wondering formhault. If a JDI user flashes a kernel meant for LGD then they get white stripes but if it will go reversed like LGD flashed JDI kernel what happens then? And if a LG user here with LGD is going to flash a JDI kernel what happens then regarding those lines :confused: These things here might sound stupid or weird but I just want to know what happens then and since I don't have those lines I can't test it but I also don't want to test it cause having lines just sucks.

I guess that many screen issues wouldn't even occur/ Lines issue would not even occur if there was only one brand used for display panel. Cause if things like sources gets messed up and you need to support more users then things go wrong.

I got one G2 without warranty as far as I know maybe I would still have 5 months warranty. so when I do something wrong then I am really screwed but I will try to do everything to get rid of it so no problem. Happy G2 User here instead of a N5 User because of formhault :good:

Hi, my g2 has a flickering srceen after flash PA Lollipop , the phone are to hot and later this flickering appear, i flash Resurrection Remix now and have less overheating, its amazing rom , i try to solve this undervolting my phone, its run ok when are cold, but start again over 40ºC . Any ideas to solve it.

Thanks in advance.

[G2 General] Formhault:
Like this?

If yes, then I'm afraid you're in trouble. To fix that, the motherboard must be replaced (a filter gets funky on the board, I think). If that is the case, perhaps a GSM service shop technician may be able to fix it by replacing the bad part, but good luck finding such a guy. Most of them would just tell ya "replace the motherboard end of story", I guess.
[G2 General] appileh:
Forumhault has a point.. But try to flash KDZ file and go back to stock..
[G2 General] Formhault:
I doubt that will work. [MENTION=2688060]1ceb0x[/MENTION]'s phone had the same flickering. He also flashed back to stock and nothing changed. Had to take it to LG to get it repaired under warranty.

Besides, if it only happens when the phone (CPU, I guess) is >40 Celsius degrees... that's obviously not a software problem. [MENTION=4276331]bronto64[/MENTION], if you're still covered by warranty, flash back to stock and bring it to your local LG service centre or whatever.

Vertical display black lines at the right

Hi everybody !

Yesterday after a day of modding my LG G2, i had an issue.

After trying to flash the lastest release of paranoid android lg g2 and flashing lastest rom stock, my screen became faded with inverted colors.

Then after rebooting it let me three beautiful vertical black lines at the right of the screen. Randomly one disappeared and an other after a thirty minutes sessions of repair pixels.

So it remain one line like in the screenshot (it's a simulation because screenshot is perfectly normal of course)

It seems a strange issue but I think benchworking softwares cause at the end hardware injuries. My phone wasn't especially hot.

My G2 isn't under guaranteed (just 1 yr and few days...)

Have a good day
[G2 General] wulsic:
[MENTION=5647116]aspartak[/MENTION] latest release of 4.4.x paranoid android or 5.0 builds? Inverted colors after reboot or during recovery

Just try that pixel stuck fixer tool again :) luckily you only have one line left.
[G2 General] aspartak:
Hello wulsic !

The 4.4.x ! I have to say when I did that flashes my phone was under battery (usb charging).

Inverted colors while recovery and went on after reboot till 2 minutes almost.

I read in forums it can be a battery default... sometimes we have to remove battery few minutes to discharge display... it s a little bit strange, isn't it ? Battery is not amovible anyway.

i had some screen flickering on cm 12(sometimes, after i moved to another app, my phone seemed like and old tv with horizontal lines). It is a know bug, but note that my problem was different from the video that formhault has posted.

After i flashed liquismooth no problem. Hope you will solve
[G2 General] bronto64:
Thanks for your answers, the flickering is like the video,I will try to flash liquid smooth, if this don't work, I will send to change the board :(
[G2 General] Formhault:
It's useless. Flashing another ROM won't fix it, but sure, go ahead and see for yourself - who knows, maybe the jolts of current that are sent to the motherboard during the flashing process fix something (it may be possible, especially since we have no idea what the **** is going on).

But if the flickering doesn't go away, and you're out of warranty... try to find a GSM service technician who knows his sh*t and is able to track down the malfunctioning component (filter or whatever it might be on the motherboard) and replace it. Otherwise you will have to buy a new motherboard, which is 100~200 USD (not cheap)...
[G2 General] bronto64:
Yes, and maybe if not solved,I try to sell by parts ;) I look a one plus 64 in my future :P
[G2 General] wulsic:
[MENTION=4276331]bronto64[/MENTION] just look for what you want but also look for oneplus one the problems before you will buy it and also look if you want to sacrifice good camera software from lg and other brands for cyanogenmods camera.

Many have tried it, in some cases issue was still there. For me after having run that magical black line removal tool for some hours without success, my black line was gone out of the blue when at some point i launched instagram and saw it disappear. Maybe the variation of colours helped cant really explain it. Next time i flashed i got the colour distortion hiccup glitch stuff and there it was again. After that the disappearance only repeated once and gone again with flashing and after that im married to my line, never seperated since :)

Hardware Fix??

After reading and reading (and READING) I found this! I believe this is what happen to my vs980.

I went to xdabbebs 985 ROM, didn't care for the interface. So I went to flash back to xdabbeb 980 v.230 OK, someplace in there got stuck in "secure boot error". Used this fix,

I'm thinking this (and the other person's failure) woulda been caused by EMMc locking up when something erased/over-written, and requires "Factory Reset" (Some kind of hardware fix) OK, so which hardward fix?

This look like it, but... Any thoughts?

[MENTION=5158501]virginwidow[/MENTION] what you can try is the FIX REAL HARD BRICK thread and read through it and if it's possible for you try to unbrick it on that way cause as far as I heard it's kinda Hard bricked.

It's not a EMMC fault in this case if you mean it for the g2, I know the EMMC erase (bug) from the time I had the Galaxy S2 but luckily I just joined the community after they had found out about it and patched it in the custom recoveries and that they already knew that factory reset in recovery mode was the cause of this problem. Your problem is wrong files, didn't read good or a typo one of these things probably.

Also guys I had received after a long time a message back from LG Support.

I just send a message back with a question about what he said about that the solution can be found in the first post: but I didn't received a link, I didn't knew or he meant this thread(I guess not) or just another link. I am kinda surprised that I got a pretty good answer back not a crappy answer about this issue. The message starts from the Dear Sir.

Dear Sir Winston,

In response to your questions on the LG G2 may be because we use different panels. If there is a fault / sitting in drivers from the hardware (kernel) to prevent the screen can not be controlled 100% correct. This can also occur sporadically on devices that run on a stock ROM. However, the risk is obviously much greater when there is a custom rom / kernel is flashed.

A solution when you actually want to flash the phone and not suffer want of the lines can be found here in the first post:

Hoping to have informed you sufficiently.

[G2 General] Formhault:
Oooooooo, don't flash custom ROMs. ROM cookers and kernel devs are stupid and only LG is smart.

F*** you, LG.

It is no fault in software. Not even they know what is going on. Many people, when they brought their phones into service for this problem, were replied with "we don't know" / "it was the panel" / "Jesus".
[G2 General] wulsic:
[MENTION=4129455]Formhault[/MENTION] maybe the software caused hardware issues? Or its just multiple reasons why its happening. We will never know I guess, I do noticed that this thread gets less posts about the lines then before and thats good. I flashed so many roms already on my g2 and still functioning fine.

Maybe LG had before a issue in their kernel sourcecode which have caused the problem with the 2 panels? But I think there is also probably something else ongoing what LG won't say else their sales could drop a bit.
[G2 General] virginwidow:
It's quite the paperweight. I must get special tiny screwdrivers in the morning, the ones I have aren't that small...

The "Real Hard BRICK" Thread (which I've read many times, as well as the service manual) Describes shorting capacitors at the EMMC chip. That's the reason I posted over here. That thread's been closed, still waiting to hear back from some of the original posters. I don't know if this is a "bug" or a "feature" the phone went into the infinite black screen boot-loop after writing my boot partitions over under Linux to clear a "Boot Security Error". IOW, it may have been designed to lock up at that stage.

Based on what I've read (there's about 10 "Help my LG G2 is DEAD" threads with no replies) and what I've covered in this thread, there is something wrong with the hardware, or more accurately, lack of detail in the documents supporting said hardware

Will be interesting to see what he responds with, some useful information (as what code corrections would solve the problem) would be truly helpful!

THANKS

VW
[G2 General] wulsic:
[MENTION=5158501]virginwidow[/MENTION] they are shorting the EMMC so that you can go into qhsusb mode it's not a bug or what but they are really only doing this to get into that mode so no EMMC bug or those kinds of stuff
[G2 General] virginwidow:
Thank you for clarification

Thanks for the clarification... I suspected the "error" was actually a safety feature I invoked trying to clear the "secure boot" problem under linux. Yay, I killed it :silly:

todays job is to dissect phone and see if I can perform said shorting. As it presently exists, the phone is utterly dead and will not accept a charge from USB either from AC adapter or PC.

So my present goal is to simply get the thing to accept juice.

Thanks

Just a open gas ganister full of fuel qustion here but are there any current Lollipop ROM's that seem to be free from this permanent screen damage ?

Looking for a fully functioning ROM -

I know it's very early still and we have no way to tell really.

I was so happy when I got this phone, so looking foward to a "vanilla ROM" or as close to vanilla as possible.

I tried a PA ROM & Carbon ROM - did not even stay on said ROM's for more than 20 minutes, - Flashed back to "stock" based ROM after find this thread.

Have not dared to try a "vanilla" ROM since.

The only reason I wanted to go for a "vanilla" ROM was the amount of customisation they have over the "stock" ROM's even with Xposed.

Ripple effect? You mean the "wave" that goes underneath the glass when you press on the screen? All phones have that - unless the display unit is soldered onto the glass (as it is for most Samsung phones featuring AMOLED displays).

My G2 has that, too. Quite badly... It only takes a more than gentle touch and the ripple shows up, though it's most noticeable on gray, so it's manageable.

If I am in TWRP, place the phone on a table and navigate the menu by touching the screen a bit more aggressively, I can see the grays changing all over the screen, where the ripple appears.
