Only your recovery and possibly boot partitions are touched, so worst case you can always get to download mode. However if the phone won't turn on at all its something not directly related. What happened before you rebooted into this state?

Mine's doing it too man. Installed the app. Phone is rooted but stock recovery. Let it do its unlock thing and said yes to disable LGE security. Then tried to reboot using the volume and home keys to get to recovery and it gave a "Secure booting failed. Cause: Device Unlocked so boot success!!" message. Then LG logo again then AT&T animation and that's as far as it gets. No recovery menu, no normal boot. Just AT&T.
You get yours figured out yet? We gonna have to LGNPST back to stock?

SO how do you get to recovery then? I tried to 2 button into recovery and am now unable to boot the phone.

the computer detects something by this name: Qualcomm HS-USB QDLoader 9008 (COM17) and the screen stays black on the LG

If you bought the phone within the last 14 days then you can return it if not you can call at&t and speak to warranty and they will send you a warranty replacement your other option is to ask if they have a local warranty center they can try to flash it or exchange it.

Are you sure you were putting it into download mode? You take out the battery. Then put battery back in the phone. THen I believe you hold the volume down key and plug the phone into the computer. Then LGNPST should recognize the phone after you change the COM port to I believe 41 or 42
Edit: You hold BOTH volume keys while plugging the phone into the computer. It needs to be completely off when you do this.
Edit 2: Here's the guide : http://forum.xda-developers.com/showthread.php?t=2302660
Switch it under device manager to COM port 41. Now flash tools should recognize it.
I'm honestly bummed that I'm now going to have to re-setup everything again. I just had to flash my phone 2 weeks ago to get rid of 2nd Init recovery to install the value pack. Now I get to do it again, then run the update, then re-root, and put my 200+ apps back on, lol. FML. I guess this just isn't the phone the tinker with. Never had any of these issues on my S1, S2, S3, HTC One, One X, Note, etc. Oh well.

Tried it didn't work thanks for the help anyways guys i have a 90 day no questions asked with Costco so i'll take advantage of that any way to export text and call logs? Too much to ask right?

Hey do you remember what version of freegee you installed? I think somehow you might have gotten version 1.0.6 instead of 1.1.0. Ive been through everything and the only thing that could have bricked you was using and older version of freegee. I didn't post on xda till Google showed the updated 1.1.0 version was live but maybe somehow you got an older on?

Bootloader NOT UNLOCKED
I was wrong the bootloader is still Locked the developer of the App corrected his app info and this shows that.

[Q] Nexus 7 Hardbricked?!

Okay, so recently installed the 4.4.2 OTA on my completely stock nexus 7 (unrooted, bootloader still locked).
Tried connecting to my PC via bluetooth (for headset) and noticed that it wasnt working (was working on 4.4), so decided that maybe a reboot would fix the problem.
And now the tablet doesn't boot. Completely unresponsive, no charging icon etc. either. Tried holding down the power button, power and +/- vol for 20+ secs to no avail. Connecting the tablet to my laptop makes windows update search for the QHSUSB_DLOAD driver. From what I've read this is supposed to be some sort of hardbrick?
I left the tablet completely stock and haven't done any tinkering except use the Wugfresh toolkit to do a backup (which only needed USB debugging on). Also the battery was definitely 60%+ before I attempted rebooting.
Help please? This is completely out of the blue seeing as I never even unlocked the bootloader or anything?
Please help!

Gone through both of them, tried the steps in the first one but I cant get to fastboot, still a blank screen and QHSUSB_DLOAD in device manager. The second one mentions in it's FAQ that the bootloader must be unlocked before using it? Mine was locked so I guess I cant use that method?

Hmm, well, last ditch would be to charge it overnight, and hold the power button down for several minutes, if that doesn't do it, you may have to just use the warranty.

Alright so still no dice. Warranty is out of the question because I bought an imported version off eBay before it was officially available on Google play here in India.
From what I've understood this may be recoverable. People have made fixes for some HTC devices etc. Basically if someone could makes a "QCN" backup from a working device I may be able to restore the bootloader using the Qualcomm drivers. Or would this tool be of any use?
http://forum.xda-developers.com/showthread.php?t=1308546
Not too familiar with all this low level flashing stuff - so need a second opinion. Will try again today evening, leaving it unplugged this time.

Yeah, I don't know much about that either, sorry, I'm not going to be much help there.

Ok, am I the first person with this problem? When the device is plugged in to the PC and I try holding down the buttons (tried almost every combo I could think of) the disconnect/connect sound plays and the tablet is re-detected by device manager as QHSUSB_DLOAD. Im extremely disappointed that this can happen even without screwing around with the system.
The warranty card with the tablet seems to imply international warranty although not specifically stated, it's from the US, so would taking it to an Asus center in India be of any use?

Downloaded them, I think a USB driver is needed for the tablet to show up as a COM port, I've tried a few drivers but QPST Configuration was unable to connect. Even if it were able to connect I dont know what to do after that, it seems that some device-specific hex/qcn/xml files are needed and this is the mode the manufacturer uses when flashing the bootloader. Does this mean that my bootloader somehow magically corrupted itself?!

That's exactly the thing, it doesnt get into fastboot mode or anything, I assume you need a working bootloader to be able to boot fastboot? If it was in fastboot I would have attempted this already.
Anyway the seller says that the item is covered under a 1 year international warranty, thats my only chance now I guess....
The thing that concerns me is that I was completely stock, locked bootloader and unrooted. Only installed the official OTA updates (no sideloading either).

For those who are interested - I finally had time to drop by the service centre. They replaced the battery and motherboard (it was under warranty). I was expecting them to do some magic with QPST or something though.

The same has just happened to me, but I'm out of luck, the warranty has expired.
Did anyone have managed to fix it with the QPST drivers?
thanks.

Lg makes it damn hard to completely brick a phone. I've seen so many people resurrect their phones from some of the dumbest sh!t you could do. There's a way just have to find it. If the phone's recognized by adb then someone could dump the boot, recovery, downloadmode partions and you could flash them back. You can try all the unbricking guides. There is a way to fix these 99% of the time I promise, just don't give up.

He tried that tool already. Well it was a modified version of uptest that doesn't require all of the extra steps. I was doing some reading and it looks like most lg phones are capable of adb turned off in charging mode so that's a fantastic idea you have about adb. I have the full kdz dump I can upload the second I get home.

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 ?

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).

If you can get it in to download mode use you laptop to flash recovery this is probably why it has failed.......remember Google s your friend.

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............

Thanks for your reply and your time. I didn't know this software "LG Up", I will give it a try this evening (in France ^^') and give you feedback then.

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 !
