Is my hardware dying? - LG Optimus L9 P760, P765, P768, P769

Hi guys. I'm currently posting here, because I've been facing some kind of extremely strange behaviour on my L9.
Basically, yesterday, I've tried up to 15 times to flash a ROM without luck, AROMA Installer got stuck at 0.00%. I had to remove the battery, and then, bootup again to recovery those times.
16 times later, the phone has decided to flash, for some reason. Also, it seems like the "framebuffer?" - correct me if I'm wrong, got stuck at the last on time, the one before I unplug the battery, getting that in mind, the screen was flickering the last frame of the recovery for about 1 minute after the reboot.

[Q] GT-I9300: Purple/pink screen flickering/freeze (not SDS) and strange behavior

Hello,
I have an international unlocked Samsung Galaxy S III (GT-I9300) that is no longer in warranty and that started behaving strangely (unresponsive) a couple of weeks ago on Android 4.1.2 (official ROM, rooted with CF-AutoRoot).
After reading several threads here on XDA I believed it was subject of Sudden Death. So I started with a factory reset and rooted the phone again with CF-AutoRoot but after that I still experienced the same freezes and started my mission to try and resolve this using whatever method was required.
I starting with trying the DFG app but to no avail. The freezing was provoked but did not go away after many days of iterations and freezes (it always recovered out of a freeze).
Next I tried the eMMC check app to verify on what version I was so that I could help my in further pinpointing the problem. It said I was safe, but while running that app the phone freezed again but this time the screen turned purple/pink and it did not recover from the freeze after several hours until I finally removed the battery. The purple/pink turned into purple/pink with black lines and after removing the battery I could not power on the phone.
In all desperation I started trying out different "SDS-safe" custom kernels, ROMs and bootloaders (all flashed using Odin on my laptop) but the problem did not go away. In fact, I discovered a very strange correlation between the time that I leave the battery out the phone and the time it takes before the purple/pink freeze occurs again.
If I wait half an hour, put the battery back in the phone and boot it (in whichever mode) it would freeze/flicker/die after about 20 seconds. If I would wait several hours, put the battery back in the phone and boot it it would freeze/flicker/die after a solid 1 or 2 minutes.
Whether the phone is connected to the laptop or not makes no difference. I also tried with a different battery but the same behavior occurs.
After waiting a solid day, in still in act of desperation, I decided to flash the leaked 4.2.2 (I9300XXUFME7) official ROM. But even after a factory reset and wiping of cache I found that the problem still remained.
Now I believe I've tried almost everything I've found on these forums I'm not sure what I can still do. It seems it's not battery, ROM, kernel or bootloader related and it also does not seem a case of Sudden Death (I never heard mention of the purple/pink flickering, and it also never snaps out of the freeze; also the strange correlation between battery out of the phone and time before it freezes is something I haven't read about).
From all the research I've done I've not encountered anyone with the same symptoms (does not wake out of freeze, purple/pink lines appear on screen when freeze starts and keep flickering for hours, there seems to be a correlation between the time the battery is out of the phone and how long I have before it freezes again when I turn it on) and I'm running out of ideas.
I believe it is hardware related (but not a screen issue) rather than software related because the USB connection with the laptop disconnects when it freezes, purple/pink flickering and no recovery; but I have no idea what options I still have.
Before I give up on the phone does anyone have any recommendations of what I can try before sending it to a Samsung repair center?
Attached are 4 pictures to show the typical process after waiting ~4 hours and powering on the phone:
Phone boots OK
The phone freezes and a purple/pink overlay appears
More and more flickering making the screen turn more and more purple/pink
The screen seems to be divided in 4-5 parts
Everything is pink and black lines start to appear
Thank you for your time.
I'd say you need a new motherboard or screen, possibly both - you've ruled out any software causes.
just had this issue
Did you find a solution, given the fact that this happened a long time ago?
I was watching a video and my screen turned pink like the 4th photo you posted.
Now it wont work, get the pink screen everytime is turned on.

[Q] So has your S3's screen ever done this?

It also comes in green, purple and blue flavours:
i.imgur.com/spABWf5.jpg (sorry, can't post outside links yet)
The phone will be up for a time and then suddenly show only that and become unresponsive. After a while, it'll reboot: the only way to power the device back on after that is to pull the battery for 30 seconds, reinsert it and leave it on charge for a few minutes. Once in a while it will crash during boot as well.
It happens several times a day now. Started a few weeks back, so I returned it to stock and removed the root access. That solved the issue, but it returned immediately after I rooted and flashed Slimbean 4.3 build 1 yesterday (previously ran 4.2.2 build 8).
If anyone has been able to fix something similar, I'd appreciate some tips. The problem has seemingly disappeared after having gone back to stock this morning.
TouchWiz...after getting used to the DPI settings in Slim...blegh :\

Stuck at Splash Screen

Hi,
I have a Sprint 4G LTE rooted with VIPER rom installed. Last night my phone freaked out, so I did the 10 second "battery pull" and it started up again. I plugged it into the charger and I fell asleep without much worry.
I woke up to find my phone stuck at the LTE splash screen of the VIPER rom. I've done the 10 second "battery pull" several times, and it doesn't just shut the phone off, it forces a reboot. Each time it only makes it as far as the LTE splash screen.
My experience with phones and computers is telling me that the OS might have gotten corrupt some how since it is stuck at the splash screen.
I do have access to the bootloader, so I have some paths I can go down, factory reset/recovery, but both those I'd like to avoid so that I do not lost the contents of my storage.
I have had VIPER rom installed for a good half year, so this issue isn't due to a new rom being flashed.
Does anyone have any suggestions?
Thanks,
-billypilgrim
When data gets corrupted, all you can do is wipe and start over. I had to do that once when running Viper as well.
Just a thought in trying to be helpful....
I used that ROM for a while myself and never really had any issues but have had a similar situation.
I pulled my sd card out and backed it all up. Replaced SD card.
Then went into recovery and reflashed the ROM.
Worked solid after that and no explanation as to why it was corrupt/hanging in a loop.
Hope this helps..

I have that happen several times. Nothing obvious that causes it. Cap'n is right need to wipe and re-flash. Here's the small trick since it just keeps rebooting on you, after you hold power for ten seconds and the screen blacks out. Make sure the capacitive buttons go out as well, that split second they go dark let go of the power button and press vol down and power to get it back into bootloader. Then you can get back in recovery to flash.

[Q] GS4 will NOT turn on

My phone has been working fine for the last year and a half regarding hardware and battery. The device itself has never given me any issues and the hardware is in pristine condition. Roughly three months ago I bought a ZeroLemon battery and case and have been using that since. The battery is also in great condition (no warping or expanding) and the case still looks brand new. BUT today when I went to use my phone (about 20 minutes after I unplugged it) I noticed it was off, and it will not turn back on at all. It will load the splash screen (it's rooted and has Xposed framework installed) but after one or two seconds it shuts of immediately. Somehow I did get it to boot into TWRP and I was able to make a quick backup, disable Xposed, run a quick factory reset and fix permissions. I flashed Cyanogen M12 and I thought everything was working fine (I was running M12 before and have been running Cyanogen for as long as I can remember.) but after 5-10 minutes the phone randomly shut off again. I have looked into this issue all day now and everyone that has had a similar problem has had battery issues. I have tried 4 different STOCK batteries today, as well as my ZeroLemon one and nothing has gotten it past the splash screen again. I am almost certain this is NOT a hardware issue but I have no idea what would cause it in the terms of software, since I haven't changed anything recently. If anyone has any suggestions please feel free to let me know. I'm looking for immediate fixes right now, so sending it back in or getting a new phone are secondary options. If you have advice just let me know in a comment or PM me, thanks guys!
Edit: At this point I can't do anything, ie: enter recovery, get the splash screen, enter odin (anything) it's like the battery is dead but the same exact battery works just fine in my friends phone.
Have you tried downloading the MDK full wipe tar, flashing it with odin, and using loki to root and bypass bootloader again?
So it turns out - after I took it apart - it has a defective power button. The actual piece that is soldered on. I don't know how to go about fixing it from here
Kind of strange but my device did the same thing today. I have tried multiple batteries with no luck. Will boot but then turn off before it reaches the boot animation. When I try to enter recovery or download mode it does the same thing.
Have either of y'all found a fix yet? My phone has the same issue (turning itself off after about 2-3 seconds after the boot animation begins).

Post number 8
Post number 9
Post number 10 finally
Any luck with getting the phone fixed?

I think he said it was an issue with his power button.

LeEco Max2 - Water incident - Fastboot Loop booting

Hi everyone,
My gf has broken her LeEco Max2 two days ago because of water. We adopted rice solution to try to adsorb as many water as possible.
I removed the phone today and charged it during ~8 hours. Since I plugged it, it has started to boot into fastboot mode, random shutdown, boot...
If it's unplugged from any charge, it won't reboot if I don't try to switch it on.
I tried to plug it on my pc, while hoping it will stop rebooting and hoped to be able to inject TWRP but it still started its loop of shutdown, reboot, shutdown...
Do anyone has an advice / solution for this ?
EDIT : I randomly tried to switch on the phone 5 days later and it worked as usual.
I don't know how to close the topic, but it's solved.

It's good that it works now, but look around for another phone. It's not avoided - I've had it twice

as @mirmad56 said, look for a new phone, water started a job inside the phone that is not finished yet.
just add SOLVED to the topic title, you can't close a topic
