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

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.

So, I've been trying to restore my phone after some modding gone bad...but now, I've gotten to the point where I can't even get to the green battery screen. My phone won't turn on, and it'll only display this screen with a phone icon connecting to a yellow triangle which is connecting to a computer.
Has anyone gotten this before?
More importantly, is this fixable? Or am I gonna have to file an insurance claim for a "phone that got dropped in a lake" this week?
Use the search option. It will do wonders. This has happened plenty of times before. ODIN can fix the problem.
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!
4. See if the phone shows anything on the screen
IF the phone screen does show the battery charger or something else on the screen after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up and volume down buttons.
6. Hold the power button as well as the volume buttons until the screen goes black.
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons!

The best luck i had getting my phone into download mode was pulling the battery, putting it back in. holding vol up+down and plugging it in. instead of going to charging, it goes to download immediately.
All messages related to "3 hardware key combo to get back to download mode so that you can use ODIN to restore", or "use adb to get to download mode so you can use ODIN" only work when the 3 hardware key combo work in the first place, or your PC can recognize the phone for adb to work
I am one of the unlucky one that does not have this 3 hardware key combo working, and am also in this sad state (Phone-!-PC). As a result, PC is not seeing the phone, so adb is out of the question right now
My phone has been like this since last Thursday (a failed attempt to use ODIN to flash JAC's OC/Ext4 kernel). All my reading so far does not give me a fuzzy feeling that I can ever get back to Download mode (ON MY PHONE)
I called my carrier for a replacement, and it should arrive this morning...
If someone can actually get to download mode WITHOUT the 3 hardware key combo OR adb access, I would love to know how
Had the EXACT same problem. Here is how I fixed it:
http://forum.xda-developers.com/showpost.php?p=7640152&postcount=4
Glad that this work for you
But not for me, for some unknown reason
No SIM
No SD Card
Pulled battery out
Make sure screen is off
Put battery in
Hold Volume up/down
plug USB cable to phone
plug USB cable to PC
Bam! Phone-!-PC
Update: Got my replacement phone.
Have SIM in
Have SD Card in
Leave Battery in
Turn off Phone
Hold Volume up/down
plug USB cable to phone
plug USB cable to PC
Instant Download mode!
Just as I read, it's a luck of the draw whether you have a TMobile Vibrant that has the 3 button key combo disabled. My first one doesn't have it. My second one does
Hi Everyone,
I know its a few threads about how to unbrick Advent Vega and how many threads is that many ideas how to do it.
I was running ViewCOMB 3.2 built 5.1 and everything was ok, but ive installed Rom Manager from Market, and tried other rom (wrong one ).
After reboot nothing is happening, i mean when i press power button for ok 10 sec and then short press again, screen is on black with backlight for about 1 sec and keep coming off.
Ive tried to turn into boot mode (2sec. back + 2 sec. power) about 1000 times already with power cable on and off, but nothing happening.
I have drivers installed on my laptop (had installed custom rom already).
I want to specify a few facts:
Is battery must be charged to full? or should start another try from flat?
If so, how to drain battery if tablet wont power up?
Is better to try with power cable on or off?
Some people saying about holding buttons for a 2 sec, other for 1 sec, what is right?
Any ideas?
Many thanks!
Finally after hours of pressing and holding power + back buttons I've sorted it.
- hold power button for about 10 sec. (to make sure device is off)
- hold back button 2 sec. (don't release)
- press power button till notification sound will come on.
Then had notification sound from Windows about new device connected. On my device list was Nvidia usb boot-recovery device.
Before last try I've charged battery to full (blue light) then disconnected power cable. I couldn't do it with battery full and power cable in (strange).
I think the main hint is to make sure that device is off. Ive noticed that even if screen is off device might be running.
Hopefully this little explanation will help

THAAAAAAAAAAAANNNNNKKKKK YYYYYYYYYOOOOOOOOOOUUUUUUU!!!!!!!!!!!!!!!!!!! I had the same problem and I thought it was bricked for like, 4ever, so THNX!!!
i had exactly the same problem last night when i asked CWM to do a backup and the screen went black and wouldnt switch on.
one way to tell if it hasnt powered off properly when its stale booting is to look under the black surround between the screen and the camera and you may see a faint blue light. Only viewable with about 5 deg viewing angle (so same as the screen LOL)
i found i could not get it into boot mode at all. No matter how many times i did it. Ending up taking the back off and pulling the battery and then trying again - guess what? Worked straight away first time!!!
I can only presume that when its in this stale boot state it isnt shutting down properly, even if the light is off etc. Although i did come across a post after sorting it that said sometimes it can take a 60 second press of the power button to properly shut it down when its in stale boot.
So now i'm back to standard modded stock rom 2.2 and its horrendous!!!!
Just finished downloading the beta ics rom exe - so gonna whack that on and have a play! Hope its as good as they say it is. If it isnt, then i'll put honeycomb back on.
I think that instead of pulling tha battery out you could also press and hold the power button for 9 seconds, right?
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.
Or try these tips: http://forum.xda-developers.com/showthread.php?t=1789135
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
So last night I forgot to charge my phone and when I wake up it's died.
I tried to charge it, but the led is blinking and then it booting up to Mi Logo (not androidone logo, before that, where there is "Unlocked" bootloader word) and it just stuck there.
I can't turn it off, nor restart. I don't know is it software faulty or my power button is not working well.
I've tried pressing power button for minutes, + vol down, +vol up&down, nothing work.
Is there is another way to restart/go to fastboot from adb maybe? (because when I tried to connect my phone to PC, the PC detected it), or if you have any other suggestion, thanks before.
Open the phone and disconnect the battery for a minute and try again
Same happened with me still phone is dead
I think you have to open the phone and disconnect the battery
