Alright, cutting to the chase. My phone is bricked. I'm unsure if its soft or hard ( no pun intended). But I'm unable to enter download mode nor recovery, let alone it won't power up.
I've done the following:
hold pwr button + vol down + home
hold pwr button + vol up + home
Neither work since the phone won't turn on. Also, prior to this problem, my phone was working but it was frozen. I conducted a hard shut down (hold the power bttn down), and from there it won't turn on.
Last thing done to the phone, I was in the middle of flashing stock everything. But can't confirm if it was fully functional as I slept. Prior to that, the phone was working fine.
Any ideas, or anyone with experience unbricking a hard brick? I did a thorough search ( my whole morning and afternoon) to fix this problem. ( I read about the USB jig, though that wasn't fully confirmed it worked; modifying the bootloader but instructions were unclear and pertained to a note 2)
If all else fails, I'll just have to upgrade ( though I'd like to avoid that).
Concerning the USB jig, can confirm it does work as I've personally used it on this phone, however, it does require the phone actually being able to power on, and if I'm correct, you said it won't power on?
You said that you tried holding pwr buton + vol down + home, but have you tried just pwr button + vol down? This is a simulated battery pull, and has worked for me in the past when my phone refused to power on

Tried to oem unlock my nexus 7 but pressed the power but to go to recovery mode. Tried different methods of turning it off, hold power, hold power + vol up/down, hold vol up & down with no luck. Now im wondering if i just need to let the battery die or something im not doing right.
If you hold POWER for 10+ seconds it will turn off. Then hold POWER, VOL UP/DOWN and it will load into bootloader. Hasn't failed me once even after F'ing up some ROM installs (for fun as tests). I've always been able to get back and fix myself.

ive held the power button for minutes with no luck...thought holding the power + vol down would work like on my one x but not luck either.
Remove the microUSB connector, wait 30 seconds, and then try again.
What screen are you actually stuck on?

so while trying to oem unlock i accidentally pressed the power button on recovery, so currently im on the white google with black screen page. am i suppose to reconnect to the usb after the 30 seconds?
Doesn't matter. Just leave the cable unplugged and then try boot up into fastboot mode again. There's no reason it shouldn't make it there.
UNLESS... you interrupted the OEM Unlock half way through. Maybe it screwed up your boot.img or something. Still, I would suspect you can get around that and back into bootloader.

thats the thing i cant get out of this google page, im trying to find out if theres anything other method i havent tried
Sorry mate. I've never had a problem power cycling a nexus device even after royally F'ing it up on purpose. Maybe just let the device sit there all alone for a bit, unplugged, and then try again in 15 minutes.
Best of luck.
problem solved-fixed with battery pull
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
Got my brand new LG V20 yesterday. It died today! Completely unresponsive, I tried all I could find, can anyone help, I’m willing to try it before sending in for warranty!
Device is LG V20 / H990DS made in Korea. It also says SEA on box so I assume that’s the SEA firmware.
I was hoping I could bring it back to life by flashing using this method https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903
BUT I get stuck right at the beginning – I can’t get into download mode! I can’t even turn the phone on, can’t get to recovery, nothing....
But, I did manage to get into fastboot once, maybe if I can get there again I can go to download mode from there? And once turned for a brief time on in detailed attempts later...
---------------
How it happened:
I updated the phone to newest software. It updated around 3 times? Not sure of the versions wasn’t paying attention. All was OK. Then I left it overnight to charge. Woke up to 100%. All OK. Then I was connecting my Bluetooth smart band, and was having trouble. So I had to off/on Bluetooth a few times... Finally, my band connected. And then after a couple minutes, phone shuts down. I tried turning it on but only vibrated, nothing happened. I pulled the battery for 15 secs, tried again, I think it boot looped on LG logo. Then I started researching xda and internet and tried a lot of things, can’t remember all but long story short nothing worked really.
I do remember, putting it on charger while off at least 1 time, it started charging (battery at around 85-95% animation charging... Then not sure if it turned itself on or I tried and died.
At one point, when I tried to power it on it said something like “kernel crash” or something with a bunch of numbers, but I think it turned itself off (or I did after a few minutes not sure), don’t remember details.
Then I remember trying powering it on, also trying power + vol+ and power + vol- a few times pulling battery in-between nothing happened.
Then I tried connecting it to PC and got windows “chime” a.k.a. USB connected something a few times. But screen on phone was dead, and it displayed as “Lemobile Android Device” something like that, was not visible in My Computer (only under devices and printers).
And I remember trying to get the PC to recognize the phone, I tried to connect holding no buttons, tried with vol+, tried with vol- and sometimes I got the chime sometimes not.
And one of the final attempts, and probably the most progress I got before writing details below, I somehow got it into fastboot mode. I have no idea how, but it said fastboot on phone screen (with some other details) and it was connected to pc. I tried writing fastboot devices and it showed my phone as connected! So I thought OK, it seems phone is not totally dead. Then I wrote fastboot reboot-bootloader and it said success or whatever on PC, but phone didn’t react... After about 30 seconds or so, phone turned itself off (screen dead and fastboot devices didn’t see it anymore) and after this whatever I tried nothing worked. Since I don’t know how I got in fastboot mode anymore (I think I held some key and connected to pc, but can’t remember) I don’t know what else to try.
---------------
After all of above, I decided I will write down all attempts exactly. So if you can help me, please, write exact steps what I should try, and let’s see what happens. I will edit post and add what I tried from suggestions.
Power Refresh =
1) pull battery out (and keep it out)
2) hold power key 1 min
3) put battery back in
---------------
Attempt 1:
1) Power Refresh
2) hold power key 1 min – nothing
3) plug into charger 1 min – nothing
4) plug into pc 1 min (then disconnect) – nothing
5) hold power & vol+ 10s – nothing
6) hold power & vol- 10s – nothing
7) hold vol+ and plug into pc (30s) – nothing
8) hold vol- and plug into pc (30s) – nothing
---------------
Attempt 2:
1) Power Refresh
2) hold vol+ and plug into pc (30s) – nothing
3) hold vol- and plug into pc (30s) – nothing
4) pull battery 10s and put back in
5) plug into pc 1 min (then disconnect) – nothing
6) pull battery 10s and put back in
7) hold power & vol+ 10s – nothing
---------------
Attempt 3:
1) Power Refresh
2) plug into charger 10 min – nothing happened BUT, it’s warm between camera and power key
3) hold power key 1 min – nothing
4) plug into pc 1 min – nothing
5) hold power & vol+ 10s – nothing
6) hold power & vol- 10s – nothing
---------------
Ready to give up and assume it’s DEAD BUT THEN......
---------------
Attempt 4:
1) Power Refresh
2) Power key & vol+ - maybe a few seconds, phone vibrates, LG LOGO shows and it turns ON!!
3) I’m shocked, have no idea what to do now... Go into settings, check software version... Saw battery was at 85% or so....
4) Phone Reboots itself, LG Logo.... and DEAD. – but warm between camera and power key.
5) plug into pc 10s – nothing
6) pull battery (10s and put back in)
7) Power key & vol- 15s – nothing
---------------
WTF at this point? It’s obviously NOT dead, but not alive either. Zombie mode?
---------------
Attempt 5:
1) Power Refresh
2) Power key & vol- 15s – nothing
3) Pull battery (and put back in)
4) Power key & vol+ 15s – nothing
---------------
Attempt 6:
1) Power Refresh
2) Do nothing 5 min
3) Power key & vol+ 30s – nothing
---------------
Ready to give up again, HELP?
---------------
Attempt 7:
1) Power Refresh
2) Go to sleep, trying more stuff in morning......
To be continued and updated once suggestions come in.....
Got a bad phone. Get it replaced
Will do it on monday, I guess it's a hardware fault then?
Seems like it. usually if it only vibrates when trying to turn on then its in EDL mode(Emergency DownLoad mode) usually because there is a corrupt bootloader. if its 1 day old and that happens then we would assume that theres a hardware fault in reading the EMMC. Unfortunatly we cannot really do anything in EDL mode without the proper tools(like a jtag box) and the proper files which we do not have.
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.

my op6 got bricked.....and when using MSM tool it shows ....."downloading op2.img failed" after an error "SHA256 not matching /or something like that" ! anyone help please !
I have a similar problem. I tried to convert my op6t to a an international phone. I held the volume up and down buttons, then plug it in to the computer. Nothing happened so I figured I would redo it. I tried to turn it on but nothing happens
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.
