Oneplus 6 weird state, Reboots, frezzing and unresponding screen. - OnePlus 6 Questions & Answers

Hello!
My Oneplus 6 started acting weird. It reboots after 5 sec, the screen frezzes and gets unresponsive then reboots. Dont know what the problem is, I have tried fasboot flash and even msm mode to flash the phone but still the same problem. Do someone know about a solution?
The biggest thing is that it works only when connected to computer (not wall outlet).
Thanks!!

[Q] Phone switches off after few seconds

Hi,
Guys I am going through some **** right now. Plese read the scenarios below and help me. I got no help at the oneplus forums.
Scenario 1 -
My phone was working fine until last night, I mean this is when I last used it. I switched it off and went off to sleep and in school today when I was trying to power it on the boot logo came and it went and after many tries the cyanogen logo came and it went away there is 80% battery. It doesn't charge also, like the phone recognises the charger but remains at 80% when I go to recovery try wiping cache and data, the phone switches off in few seconds. I can go into fastboot and stay for like 3 seconds then the phone switches off but I can connect it to power and keep it. I am on stock, latest CM12S. The only unusual thing I did yesterday on my phone is that I charged it using a different adapter but same cable. I can't seem to find this issue on google.
Scenario 2 -
Guys,
My phone's really messed up and I am scared to tell my dad cause he warned me before getting it for me. After the OnePlus logo comes, when I press the volume button and hold it, it works and as soon as I leave the volume button, the phone switches off. What is wrong? Do I need to send it back. I got it from Oneplus.cn so I am a bit worried and it's going to be tough to check what's happening.
Scenario 3 -
I removed cm12s and tried to flash oxygenos and I failed so then I installed cm11s and still have the problem, my phone can only boot in safe mode and as soon as I leave the volume button it switches off, same for recovery. Used the onplus toolbox by Inthiaano to install CM11S 44S.

Nexus 5 Charging issue (in a weird way)

so i have had a nexus 5 for about a year now, my brother had it from launch, one day it bricked and my brother bought a iphone, so, ofcourse i reflashed the rom, and it worked again, but with weird buggs and quirks, now suddenly it didnt want to charge, so i have decided to factory reset, and ive also replaced the battery (i had one laying around and hadnt come around to puttin it in)
so, heres the issue:
when the device is off, and you plug in the usb cable, it recognizes it, and starts the charging animation, then this animation crashes and it restarts, it does this, over and over again..
when i go to fastboot mode, and i plugg in the usb, my laptop (and pc) recognizes it, and then gives an error, just so it can start the cycle over again, and i cant get adb working like this...
any help?
Which ROM did you flash?
Edit: Oh, and how did you flash it?

Random freezes and bootloops

Hi, im posting this here because i could not find solutions or similar problems in the internet.
My redmi note 6 pro global version with locked bootloader is Just 2 months old and im having this issue with him, It randomly freezes the screen and nothing responds, touch, Power Button, only a restart brings It back, but sometimes It comes back normaly, sometimes it turns on and after couple seconds freezes again and again, and even a bootloop i encountered. I've already hard reseted It 3 times but no results. This happens once in a while and i never saw something like this. I have no clue what could be If not a hardware problem.
Thanks in advance

Sudden black screen, one pixel lights up.

Hello
Today my SM930F seems to have freezed. Basically I picked up the phone and the display would light up only one pixel. Others are utterly black. I tried rebooting the phone. PWR + VOL DOWN, tried rebooting into recovery and download. It seems to reboot into them just fine, but I can't operate them, beacuse nothing shows up. Screen is dead black. Phone is recognised by my computer and Odin. Seems to be charging normally when plugged in a wall charger. As I recall the phone was running a stock rom. LED and soft keys light up normally. Glass is a cracked on both sides of my phone, but I think it's a software issue. In other threads people have reported that Spotify app can cause similar problems and I have it installed.
EDIT: it seems that I cannot boot into download - I tried it, plugged my phone and flashed a stock rom. Whole process ended in 5 seconds, so it seems that the device is either still powered on or hangs on a bootloop - idk

Poco X3 NFC - Can't access bootloader, fastboot or system (bootloop)

Hi. My close friend has this issue. I'm posting this because she can't figure it out by herself. A month ago, her phone downloaded an update and she installed it. Since then, the phone has restarted by itself without any reason, just random restarts and the frequency of restarts was more frequent with each day. Fast forward to this day and the phone is constantly turning up and shows the POCO logo and restarts by itself. This loop is not ending until the battery is completely dead. When trying to access fastboot or recovery mode, she can get there but only for few seconds (until the device restarts again) which is not enough time to make any changes / factory reset. She did not accessed developer tools in system, so the bootloader is still locked. Holding down power button does nothing. ONE SINGLE UPDATE screwed up whole phone. Can't do ****. There's no SD card or SIM card in the slot. Is there any "hack" to stop the phone from restarting itself? Note when the battery is completely empty and she plugs the charger, the whole nightmare starts again. I'm lost. Did you guys have any ideas what to do? Or is the repair centre only solution? (She cracked glass of the display, i'm not sure if that voids warranty. [it's not glass COVER, it's the glass which is part of the display])
Is this device unlocked? If not, then RMA.
If it is, my best guess is to get the device into recovery (or fastboot?) and immediately connect to PC.
If it holds, leave it there as it will charge, although at much slower rate.
When charged, use TWRP to try to reboot to system.
If it doesn't work, then factory reset.
Sadly, i can not get to recovery because in about 2 seconds the device will reboot. There's literally no time to make any changes - factory reset. Also the device is not unlocked. I hope RMA accept the phone even though it has cracked screen . Thanks for response anyway
Then RMA it is. If you're in EU they'll have to take it, even with the cracked screen.
But does the reboot happen even when connected to PC? Two seconds is enough to plug it in if you're fast...
Yeah, we tried every possible idea we can think of. Pressing the toggle button from different angles with different intensity to make sure it isn't stuck inside, covering up the proximity sensor (yeah makes no sense but even that we tried, lol). Tried with connected to PC as with classical charging brick. No change. Back in those days where smartphones doesn't have unibody construction and you were able to take down the back cover and remove battery it was way simple. Nowadays it's not possible to stop the phone from booting itself until battery is completely empty. My friend says the problem started about month ago, when the phone annouced that there is an update available so she downloaded it and installed it. Before that, there was no problem with the phone whatsoever. Maybe it's caused by some kind of virus but IDK which apps she was using. She didn't have rooted phone not unlocked bootloader in developer tools. Also i googled that it may be caused by "Airtel Thanks" app which she didn't have installed aswell. I will keep this thread updated as what happend to the phone cause i'm also interested what went wrong and to help future users who will struggle with this problem a solution. Thank you.
CaptainFedora, did you solve the problem? I have the same issue...
Yeah, actually. Sorry for not posting the answer although it was definitely her fault. It was the power button being pressed down (which made continuous bootloop). But the button was somehow pressed deep into the phone's body. So complete dissasembly was needed.
Btw. my friend lives in other country so we discussed this problem over internet. If i could have the phone physically with me i would definitely know what was the problem.
Hi.
Yesterday I had the same problem, the device kept restarting every 10 seconds, it didn't even come to any screen besides the first one with the POCO logo in yellow.
Things I tried that did NOT work:
restart
hard restart
fastboot (it did enter the fastboot mode, but only showing the picture of the 2 robots and after 10 seconds restarting again to the POCO logo image)
plug it to power
plug it to computer
After 3 hours of continuous restarting and trying anything I could find in the internet and I could imagine of (except extracting the battery because it seemed complicated and difficult to revert), I tried randomly something that miraculously worked...don't ask me why.
pressing the power button shortly and quickly around 30 times (it might have worked after 10 or 20, but I just kept doing it a little longer
Afterwards it just started as if nothing had happened...doesn't make any sense, but I just wanted to tell you in case you are in a similar situation and desperate to not lose all the images and videos as I was yesterday.
