S8 plus Dead black screen - Samsung Galaxy S8+ Questions & Answers

Hi,
A month ago, first time screen of my S8 plus (15 months old) went black, i can see the phone is working fine apart from screen, tried force restart, every button combinations available on other forums, nothing worked. After like 10, hours screen went on by itself. It lasted a week and screen went off again. Again same thing, it went back on by it self after few hours. I though it might be the corrupt software, so i flashed the factory rom. But no luck. This cycle kept going on for a month.
Now since last week, screen went dead, not turning back on. I can connect the phone to screen via smart view (Bixby voice helps there surprisingly), and see everything else works fine.
Phone is out of warranty, so i cannt just go to samsung and get a replacement.
Does anyone have any idea, what is going on, and if they have face any similar issue and what to do with it.
Also, one weird thing. I dont know if its related to the issue but I noticed every time after i factory reset or flashed stock rom, some random files start downloading itself via download manager and every time i tap to look for the name or info, it just disappears, tried to find it among apps and file, nothing can be found.

T-Mobile Wing Weird Bootloader

Hello Guys,
I started to have problems with my wing and end up in three-color bootloader screen. I can tell you that I am not playing around with my phone. I do not even install any software not to risk its basic phone functionality since I am using this phone as a business phone. So, no crazy rom flash or etc has been done prior to this problem.
My phone started to have problems with answering calls last week. When it was ringing, it was keep ringing and I was not able to take the call even though I was pressing every possible buttons on the phone. It was locking.
I noticed that phone was locking the buttons too. So, I selected "do not lock buttons when the device is off". But, this does not have any effect. Phone was keep locking my buttons.
Last night, I noticed that my phone was unresponsive once again as usual, I soft reset the device, and it booted to the three color screen (I think you guys call this bootloader screen?) where it says "IPL 4.26.0002" and "SPL 4.26.0000". Tried to soft reset probably another 10 more times. same thing...
I took out the battery, went to sleep. Put back the battery in the morning, it booted to the OS and phone is running. But none of the hard buttons were working. It also hangs up the incoming call after first ring. I soft reset the device once again and it went back to the three-color screen.
I went to the Tmobile website, and found that there is an upgrade ROM. I downloaded and ran that program. It said that it installed it to the device successfully, and then the device rebooted itself. Guess what, back to the three-color screen.
I have been reading your forum since morning, and read a lot about brick phones etc. I tried couple of the techniques for recovering brick phones, but nothing helped. Hopefully, someone here can tell me what is going on, even though if the answer is to throw the device to the trash.
Additional Observations
It looks like nobody is interested
I have other observations.
- When "do not lock buttons" is checked, phone starts acting even more weirder. it generates keystrokes by itself. Camera starts taking photos.
- If the battery of the phone is out at least an hour (I don't know why), phones boots fine. If you soft reset at the moment, it will always goes back to the three color bootloader.
Can this be a virus?

Sprint TP2 endless reboot loop - keeps restarting itself

I hope someone can help me, I have a Sprint Touch Pro2. Last night it randomly started rebooting itsself, i was not loading a new rom, i was not installed any software, i wasn't doing anything other that texting and IMing people. After i removed the SD Card, there were a few times i got it to load to the unlock screen, but once i got passed that it would say "starting device activation..." or something like that. Then i got it loaded but Touch Flo 3D would not automatically start. So i removed the battery and restarted it again and i went to bed and left it charging, and it kept restart itself again, when i woke up it the phone was dead, and will not turn on. The charging light is on but it will not turn on.
This happenned to me, i ended up having to exchange the phone.
have u tried a hard reset. U can do this by holding power button and call and end keys.
Phone must be off and it will completely erase your data
this sounds like what my phone is doing. is there a fix? i think im sol because i didnt buy it though sprint.
Not Hopeless
This happened to my Sprint TP2 I soft and hard-reset it but it still went back to the reboot loop.
I put it in the tri-boot screen and re-reflashed the stock ROM and all was well.
Same here
The same thing is happening for me right now. Soft-resets aren't helping. It's sporadic, however, sometimes saying it successfully activated and needs to reboot (then going into activation right away), sometimes saying it failed, and sometimes not coming up at all (but I'm pretty sure it's running in the background, even if I hit cancel, because the phone is very warm and the battery drains very quickly).
I took it to Sprint and they confirmed it was already activated. They tried manually activating it, succeeded, and it still kept doing it. However, both them and I were able to place a phone call, text, and visit a website... so basically it was working. But, like I said, this constant nagging of activation was running in the background sucking juice and killing performance. Their diagnosis was "it's acting weird". The main home screen clock has also been stuck at 0:00 ever since this started (though the lock screen clock and clocks in the World Clock screen are correct).
They said I could go to their service shop and do a diagnostic and backup/wipe/restore or they'd replace it under warranty if it still didn't work.
I figured I'd just try the hard reset myself tonight. Will post how that goes. I'm not sure what this "tri-boot" screen is, but I'll do some searching and check that out too.

What the heck happened to my phone?

I have a Verizon Galaxy Note 2 i605 that's unlocked, using Straight Talk service, rooted, and was running stock Android version 4.1.1. On Thanksgiving Day, I was going to have dinner with friends. From my computer I found the location on Google maps, then sent the map to my phone. That's something I'd done many times, but this time when I clicked the link, it flashed the conformation asking if I was sure I wanted to load the map. When I clicked yes, the screen dimmed then immediately brightened and dimmed again. It continued this flashing at about 1/2 second intervals. During this time no buttons or combination of buttons had any affect on it. After about 40 or so seconds of this, I took the back off and removed the battery. I waited about a minute before reinserting the battery and replaced the back. I pushed the power button and fully expected it to boot normally. Boy was I in for some disappointment. It not only didn't boot, it didn't do anything. And hasn't since. No boot, no download mode, no recovery mode, and not recognized by the computer when connected by USB. It is dead. Does anyone know what happened, or more importantly, can it be revived?

Please Help! Stuck at boot screen...

Hello. Sorry in advance if this is the wrong thread. I own a pretty old 1 year old tablet that currently has a problem.
Important info: Android 5, No access to a computer for 2 weeks (vacation), slightly cracked screen (still works), I had to install a Play Store apk as the one I had previously was corrupt. Tablet was functioning fine until the moment of the incident (except for the play store apk, which I later fixed).
Minor detail: Once the screen turns on after a restart the pixels near the top of the screen seem to turn purple for a second when I tilt the tablet.
Here is the story:
I was watching a YouTube video and suddenly my tablet froze. I thought: "Uhh, another freeze how annoying," and waited for it to load. I did not unfreeze. I thought: "Well, I guess I'll be fine if I turn my tablet off and on. This is where I got worried. My Power key was not responding. I tried the volume keys. Nothing. I tried connecting a mouse and moving it around. Still nothing. I thought "Ok, lets try restarting it" I did that by holding the Power key down for 10 seconds. To my relief, it turned off. But when it was turning back on again, it was at the loading screen for a little to long. It usually takes 5 seconds to get past the loading screen and enter the boot screen. I decided to wait. 1 minute: nothing. 5 minutes: nothing. I got worried. I tried restarting the tablet again. I restarted successfully but was stuck at the loading screen again. The was no movement on the screen. Only the loading screen. I decided to try the restart backup button which I could activate by putting a pin in a small hole at the back. It had the same effect holding down the power key had. I decided to ue my backup plan: recovery mode. I successfully entered recovery mode. I chose the option "clear cache" and tried to boot again. No changes. I did a scan for any root errors. it said that there were 5 errors, but there was nothing I could do about that. I tried doing a factory reset, then booting up. The reset was successful, but I got the same effect as always. No changes. I gave up and tried to google a solution on my phone. Most of them told me to install a PC program, but one told me to do the same thing I already did: reset, restart. So I decided to let the tablet sit with the boot screen for 2 hours. When I came back, there was no change at all. I tried searching again for a solution. A YouTube video said that the boot time after factory resets may be long, so I decided to reset and let it sit for a bit. 20 mins later, no changes at all. Finally, I gave up and now try to ask for help here.

Was your device rooted? Did you have TWRP custom recovery installed? If you don't have either of these two things then your only option is to flash the stock firmware via PC.
Do a google for:
"Return to stock (your model number)"
If what you need is out there somewhere, that woll find the instructions, the tools and the file(s) you need.

xperia xz display(black screen) not working (randomly) help me.. please..

1.
First, the current situation is that the screen does not come on while the power is turned on.
If you look closely, the light of the screen comes out, but it is a black screen.
So when I press the power button several times, I sometimes see the screen once, and when it is bad, the screen keeps blinking only on the black desktop.
No matter what I did, it was not restored, I disassembled it, pushed the battery part for a while, then contacted me again, and the screen started to come out again! However, after about three hours, the symptoms began to appear again. Now I keep repeating this phenomenon and just use my cell phone.
2. ((First things I did.))
I used the flashtool to update my stock firmware. Soon after I knew the wrong thing, I put the firmware over again. I tried to get the firmware for my country. Then I was disappointed to see that the TTA-VOLTE I wanted was still not working. So I decided to install Android 9.0 (Pie) and install TWRP and install it as WIPE. It was the beginning of all these.
Since then the above symptoms have been manifested and the stock firmware does not work even if you do anything
please... save me... :crying::crying:
