the device gives no heartbeat, no charge, no power on. The PC does not recognize it when plugged into USB.
The device died ...

You need to manually enter recovery. I don't have that phone so I don't kbiw if that rom is even the correct rom for your phone. To enter recovery on most devices hold volume up, home button and power. Roms are flashed in recovery not apps.

And is your battery full? Does adb recognize it?
If the rom is definitely for your phone I don't believe you've actually hard bricked.
U may wanna check that

Search man. Dont give up yet. Are you 100% sure that rom u tried to flash was for your device? If it wasnt then yes u may have a brick. If you're sure it was thwn keep searching there may be hope still. Maybe even try the method u used to root in tge first place?
? http://bit.ly/18WHgY4 ?

It might bricked
At first make sure your battery is healthy and try to charge it,then use one of unbrick methods available,take your phone to download mode and flash one of official p936 *.KDZ roms
it's better to flash android 2.3 versions for unbricking

Yeah not good. Basically the phone is an expensive paper weight now. I had the same thing happen to me a few months back and had to get a new phone. Your options:
1. Contact your phone company and see if it can be handled under warranty.
2. Contact LG.....same thing.
3. Spend $50-$100 on having a third party fix your phone.
4. Buy an expensive j-tag box and hard restore your ROM: http://forum.xda-developers.com/showthread.php?t=1628254&page=1

[Q] How do I get download mode working?

I rooted my phone about a month ago using PurpleDrake and now I'm on SkyDragon G3 V0.0.5 w/ TWRP. I had never been able to boot into download but thought nothing of it since it wasn't crucial at the time. Then, yesterday I accidentally took the new OTA update, but was able to fix it with the ADB commands that others have posted. Being able to get into download mode would have made life easier so I tried to fix it today. Flashed stock boot.img and tried to re-run PurpleDrake to see if I missed a step but it won't detect my phone for a reason I don't know. At my wit's end.
Not being able to get into download mode is a concern in case I ever to fully return to stock. Wondering if any one has some insight on how I can do that or if there's some image file I need to flash, etc.?
Thanks!

Thanks for the reply. Sorry, I could have been more clear in my post. I have visited that thread and held volume up while plugging my phone in, but all that happens is the LG logo screen pops up for a few seconds, then the phone shows the charging percentage. When I try to do it from the advanced reboot menu when the phone is powered on, it simply reboots into the system. Same deal if I try to do it from TWRP. Really not sure what I'm doing wrong here. Is it possible that I somehow corrupted the bootloader or something else that's hopefully fixable?

I think you made a wrong procedure.
Take the battery out and put back in.
Press and hold volume up button.
Plug in the cable.
Release the button when you see download mode screen.
In addition, make sure you have LG PC Suite with phone driver installed.

Thanks but I have already done this with the same result as I've described. I know how it is supposed to be done with the hardware keys and I am using the stock data cable. Even watched a YouTube video demonstrating how it is to be done. Are there any other possibilities?

Just tried it with my nexus 7 cable on a different usb port (which I had done couple times before) and it worked this time! Not sure why or how but appreciate the help, everyone!

Stuck on a sudden BootLoop

Hi All,
As mentioned in the title, my Tabt S T700 has suddenly restarted last night when browsing and is now in a bootloop.
I can't go into recovery but download mode is working.
So I am assuming that I should reflash the recovery with Odin.
The problem is Odin doesn't want to help as it gets blocked on the "Initialization" Step. I tried 2 different PC's, different USB cables but nothing works.
Cand you guys please give me a help?

Try while in download mode , press power, home, and volume down and volume up all at the same time and you should boot into a black screen as soon as you see the black screen quickly press and hold power, home, and volume up until you enter recovery.

Thank you for your answers DUHAsianSKILLZ and maxal.
@maxal, if i do this i only get to the "Samsung Galaxy Tab S ...Powerd by Android" screen. Should the device be connected or something?

That's right you do get the Samsung Galaxy Tab S splash screen you need to keep all power, home, and volume up held a bit longer until you go into recovery

I Kept pressing for about 40 seconds, still nothing.
If I release everything the tab just remains on this "Galaxy Tab" Screen.

I take it Odin was working fine before your problems started, hopefully someone with more knowledge will come on and help you.

I was having similar trouble with my SMT800. I could only access Download mode, from there I tried Odin, still wouldn't work. Reinstalled Odin (3.10) and it worked. Not sure if that helps or really why that worked for me , but it did.

[Q] help, phone won't turn on after flashing 20b

Hi, I tried to flash 20b through twrp tonight.
I did factory reset, then flashed the bootstack, then flashed the system. But after that, my phone won't power on. I tried to remove the battery, holding power button for a long time, or power+volumn down.
The phone just does not respond at all. Can anybody help? Thanks!

take the battery out and put it back in and try to power it on. Repeat a few times, if that doesn't help we'll try other things.

when I had that problem I figured out that it was the battery that was making the phone act weird. Since LG sent me another battery when they had the promotion I used the other spare and that fixed it for me.

This happens right after I flashed the new system, I doubt it is the batter problem. If I plugged into the computer it still won't power on.
(If I remove the battery and plug into computer, the screen of the phone does show some symbol, probably regarding missing memory).
Let me try to see if I use kdz flash to reinstall the system. Thanks for the help.

This is why You don't flash the boot chain unless you absolutely must. I was running 20B with the old boot chain (other than rpm, that was updated) and it ran just fine. If you get a bad flash on the boot chain your sol.

LG G4 H815 - Stuck on Bootloader State

Hi to all,
yesterday I attempted to install LineageOS on my LG G4 h815.
I followed this tutorial -> https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
Everything went fine. I was able to boot under LineageOS reinstall my apps etc, etc.
This morning when I woke up everything seemed normal too. But, few minutes ago, I sent an SMS via Google Messages the phone froze and then black screen.
When it froze I had 97% battery.
Ï tried to reboot it with power button -> Nothing.
I tried to remove the battery put it back on and pressed the power button -> One tiny vibration but nothing
I tried several times the same last process and finally I managed to get the screen with "Bootloader state : Unlocked !", but I cannot go further.
If I connect the phone with a USB cable, wether he's "turned on" or turned off no led is blinking.
Does someone have a clue to fix this or has ever encountered this issue ?
Tanks in advance and do not hesitate to refer to an old post. I wil check (but found no same case).

Just to perfectly understand.
Are you advising me to flash my recovery with an older version via my laptop (I imagine via adb/fastboot) despite I can't even get my LG be recognized by my laptop ?
Will the adb/fastboot command be functional as the LG seems not to be recognized on the PC?

The best way to get your laptop I recognize your phone is to get LG up running then with the usb plugged n drop the battery out then put battery back in then close off LG up.
Then start it again and when it go's into download mode the pull usb and close off LG up Then plug it back in with dos prompt open............

LG UP had no effect on the phone.
However, now the phone seems to have 0% battery and when I try to boot it I get the graphics to plug the phone on a source of energy. Once I do that the front led is blinking in orange (I guess because I had less than 1 or 2% o battery) and now the front led is still lit on in orange. Is this a good news or I'm hoping for nothing.
Anyway tomorrow I will try to get it back to my retailer.
Does anyone succedeed to get it replaced by LG even if the bootloader is unlocked ?
Thanks.

After a little journey to the repair shop of my retailer everything seems to work correctly, for the moment, with LineageOS !
Thanks everyone for your help !
