I just encountered a very strange and worrisome issue today. I successfully rooted my OnePlus 6T and installed Magisk with TWRP following these instructions.
After reinstalling my apps, installing the AdAway apk, and rebooting (using the system dialog) after I was prompted to, my phone refuses to start.
The screen is all black with no signs of any activity. I tried holding the power button for 10+ seconds in various combinations with the volume buttons. None of them worked. The phone is definitely not battery dead because I clearly remember the phone was plugged into my computer and at 83% at the time it shut off. I hardly believe I bricked my phone because the rooting process was 100% successful.
Any help would be greatly appreciated.
Plugging in your phone have any signs of activity? Might be in qcom mode. Worked for me to hold power and volume Up for like 30 seconds.
I've had this issue a few times, I was always able to get it to turn on by holding vol up + power for an extended period of time.

It seems my Nexus 7 seems to be hosed.
It was running the latest android os as pushed out by google (maybe 4.2.1?) Not sure what I did, but I am in the APX mode and I cannot exit it. The screen is completely dark, and I am not sure it is working when I press the buttons.
I have held:
Power button for 60+ seconds
Power + volume up
Power + volume down
Power + volume up + volume down
If the device is plugged into my laptop, I get a beep after holding any aforementioned combination indicating that the system detects the device but it shows up in the device manager as APX with a question mark.
I have opened the back, and disconnected and reconnected the battery.
Prior to noticing it was not working, I set a torrent download using µtorrent. My initial guess was that the battery discharged, but I have been charging it now for a few hours without any resolution.
Please help! I am past the returns for Walmart, and I do not want to ship it to ASUS to have it repaired.
Bump.
This is frustrating. I have never owned an android tablet before, and I had no intentions of rooting it. Now I have no idea if I can even recover it. Other threads are saying I am hosed because nvflash does not work on the nexus 7.
Any ideas besides throwing it in the garbage?
Try letting the battery die.

Hi guys, my Nexus 7 stopped turning on after I turned it off through the bootloader. I turned the device on in bootloader mode, and navigated using the volume keys to "Power Off" and hit the power button. Now it won't turn on at all. Plugging the device in, Windows responded with a sound and said drivers installation failed. Any help appreciated!
EDIT: After plugging it in for a while, I pushed the power button and it turned back on! But it did give me a scare. I'd like to know if I just got lucky or at least some explanation on why that occurred. Again, any help is appreciated!
SECOND EDIT: I figured out why. It was because I held Volume-Up when I turned the device on after shutting it down with the bootloader. For some reason, this causes a soft-brick. All it took then was to plug it into the wall, wait a minute or two, the long-press the power and then let go, and the thing will kick back to life.

That is not a soft-brick, that is APX mode.

I've looked online, especially on here, for solutions to my problem but they all seem to assume that I can access fastboot. Here is my specific problem:
I was using my phone and suddenly the screen went black. It rebooted once into the OS but immediately restarted and has been stuck in bootloop for 4.5hrs thus far. I have tried to wipe cache, enter fastboot, power down the phone but nothing worked and it kept looping. Even when I powered off. It's like the power button signal is malfunctioning because it doesn't always reboot at the same exact point in the boot cycle.
My phone is stock, no custom anything, and is encrypted. My only thought right now is to let the battery drain fully and try to boot again after that. I have not tried to enter fastboot while connected to a PC, but I have tried to do it just on the phone.
I have not been home yet so I do not have access to a PC I can actually do things with at the moment. Any help is much appreciated. Thanks!
EDIT: I am home now. Going on 6hrs of looping and nothing has changed.
EDIT 2: The battery was drained. It starts to charge but instantly tries to enter the boot loop again so the battery never gets enough charge to do anything; thus, I can do nothing to save the phone, I don't think.
If its some malfunction with power button, try to abuse the button gently. I used to do that with my Nexus 5 when its power button gets stuck inside causing bootloops.

The button itself is fine, it works as it should and is not pressed down; however, there might be some sort of internal problem causing the phone to think that it's being pressed.
I had rooted my dad's lg g2( D802) and installed twrp using an app named autorec as it was recommended by many people in the internet and had very high ratings and downloads in the play store. Everything was fine for a few weeks till I noticed that the app had an update. So I flashed twrp again from the app hoping it was a newer version and it said it completed the operation successfully. Then I just used the phone for sometime and after that I switched off the phone to enter the recovery. After it switched off, I pressed the button combination for entering the recovery but nothing came up. Then I attempted to just boot the phone and kept pressing the power button but nothing came up. I even kept pressing the button for upto a minute to hard reboot it in case it was just a case of hanging but nothing came up.After that, I plugged it in for charging and attempted to boot again. After I kept pressing the power button for about 30 seconds while charging, the led blinked red 8 times, paused and repeated itself as long as I kept holding the power button.
The problem is that it even the screen doesn't turn on.
I searched for this issue and saw that many others were facing this issue. I tried the following solutions given by them which did not work:
1) Holding the power button for a long time
2) Keeping it for charging until it's full but nothing comes up and the phone got heated up very much untill I stopped it a few hours later.
3) Removing the back cover and detaching the battery power cable from the phone after after waiting for sometime, reattaching it.
My dad showed it to the lg repair centre but they told him they need to replace the whole board which is very expensive, especially considering that it is a 2+ year old phone. My dad is very angry at me and probably won't let me touch his phones ever again if I don't fix this. Please help me.
Thanks in Advance
Edit: the charge was at 45% when I switched it off. Don't think it is because of low battery
With the phone pluggged into your computer, does the computer recognize the phone? And if yes, what does Device Manager report it as being?

more info... what variant? phone does not boot.. can you press vol up then plug phone .. does download mode works... stay calmed this can be fixed..:fingers-crossed:
I haven't tried plugging it to the computer. The way to enter download mode is holding the volume up button right? Thank you for the suggestion. I'm away for a few days but I'll tell my dad to do so. I'll post what happens then. Variant is D802
OK I told him to do that. When he pressed the volume up button and then plugged it to his computer, 13 new partitions showed up in windows, and it is telling him that he needs to format the positions to use it. But nothing is coming up on the phone
Do NOT let Windows format the partitions(!)
Use the SRKTool instead to unbrick from qhsusb_bulk mode:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076
Afterwards use LG Flash Tool 2014 to flash the KDZ for your variant:
http://forum.xda-developers.com/showthread.php?t=2432476
It's better to let the battery charge to full first. Shut down the phone by holding PWR button for 10 seconds, then plug charger. It should work even in bulk mode.
Did you try these simple things...
shutdown phone keeping powerbutton down.
Start pressing power button & vol down....when you see LG logo for couple seconds. Release fingers and press vol UP and vol DOWN, same time. No power button.

But the problem is, even the screen doesn't turn on while on download mode. I'll surely try out the unbrick tool but will it work since normally, the download mode screen comes up. That thing is 760mb. I think it'll take some time for it to finish. (Ultra slow internet connection )

The lg logo doesn't come up when I do that. If fact, even the screen does not turn on
Thank you guys! Srk tools worked! Again thank you very much
Hi,
I slept last night with ~40% in my OP6T. When I woke up, the phone wont start anymore. I am rooted with the latest Magisk, and latest stock rom.
When I press the power power button, it doesnt even show me the screen where I have the bootloader warning. I've tried pressing the power key alone for 15 seconds, power + up volume for 15 seconds , power key + down volume for 15 seconds, power key + both volume keys for 15 seconds but nothing happens.
I just cannot get my screen to start:crying::crying::crying:
I have also tried connecting my phone to the laptop, I get a "safely remove OP6T" notification in the task bar, but my phone inst identified in the storage..
If anyone could help me, that would be greatly appreciated.
Thanks a lot

It's probably out of charge, happened to me and I just left it on charge for 15 minutes and then held the power button and it worked.

Hold pwr and up button for a couple of seconds.
So after 1000s of attempts, its started on its own (on the 1001th ) attempt when I held the vol up and pwr button. It wasnt a case of battery drain as I had only connected it to the system for 10 mins and the battery when it started was 53%.
Is there a way to find out how it tuned off ? some crash logs or something ?
Can an admin please close this thread ?
Yeah it seems like there's an issue with the phone loading up after it's went dead..and I've had that issue a few times where I had to play with it for an hour in order for it to finally load...I even knew it was dead and plugged it up to a charger and it would stay on the bootloader screen and I left it on the charger for an hour or so..and then held the <pwr><vol+> to shut it off and when I did all that I then powered it on and took the charging cable out and it still said it was low battery..so while on the unlocked bootloader screen it wasn't charging(weird)..so after fooling with it summore I finally got it to charge just random didn't do anything I hadn't previously done and all was good. But it seems like this only happens after it dies and I don't Kno if the unlocked bootloader is the issue or what but it's aggravating to have to fool with it for that long.
I think there is something wrong with your ROM.. Are you rooted? If I were you, I'd wipe the phone completely and install a new Rom, redoing the setup from scratch..
I have wiped and rooted with magisk and twrp recovery installed.. and I have zero issues in the current setup..now only when it has died did this seem to happen..oh I have wiped 3x because of bootloop and soft brick previously..so I don't think that is the solution (wipe and clean install)..just weird

I haven't tried this, but from what I've read, using the MSM tool is the only sure way to completely factory reset your phone.. Using anything else could leave remnants in the ROM causing problems..

For some reason my fastboot drivers are not working anymore, the MSM tool is not a option for me.
