LG G3 Dead

Hi
I have LG G3 of AT&T that says D850.
I tried flashing it with a custom rom and after i restarted, it keep going into FASTBOOT mode and i couldnt open the phone.
I tried FlasTool to goto stock rom but it kept saying that the device model mismatched with the rom (i downloaded the ATT D850 dll and TOT).
After that i tried erasing the recovery, aboot, laf through fastboot. Just after i erased it my battery went out and phone goes off.
Now i cannot even turn on my phone. it show no screen at all.
However if i connect the USB, my pc detect something as a removeable device on computer.
Is there any way i can unbrick it?

Take battery off for few secs and put it back. Press power button and volume down at same time. When lg logo appears release and press again. You'll see white page with warnings. press 2x yes and you are now in twrp recovery mode.
Try factory reset. If doesn't help try install any rom from sd card or ext card.

There is nothing appearing by pressing the power button.
After I erased boot, recovery from fastboot, the LG logo stops appearing and phone is behaving like its not even starting up.
Even in flashtool, it doesn't show any model number or imei now.
Earlier if was showing as D8559

power and vol down together. If nothing then i would search how to unbrick

I tried both but flashtool is not recognizing my device, it shows no imei and pid.
Plus my device is d850 but it shows the error that device model is mismatched with the files however I downloaded the d850 files.

Dude you hard bricked it. I fell into the same exact situation. Came to flash stock but faulty win8 drivers caused my flash to fail at 14%...and everything went horribly wrong.
you can see a reply i wrote earlier that can help you:
http://forum.xda-developers.com/lg-...overy-mode-t3162652/post61991431#post61991431
BUT both links in the reply are to fixing a hardbrick for international D855 models and i am not sure if they will work with you.
Honestly your phone is not dead. There is many ways to fix it...if not now then eventually. You can find many threads with the same problem. Honestly i was sick to my stomach when it happened to me...you must be patient and make sure you read everything carefully before doing anything and I'm sorry this happened to you
Good luck!

Try to take out the battery. After put it back and press the volume up and plug in a the lg micro USB to your phone but before doing that be sure it is plug in to your computer and wait until you see the download mode. I forgot the video link but just search up unbrick,unroot lg g3 on YouTube and search for the video that you see a lg g3 with a blue screen and a number 3 in the middle. After you find the video use it to guide your self to repair your lg g3. Hopes it helps please message me back if you do it and if you what I can help if it doesn't help.

I hope you know to enter download mode your phone has to be off. The while holding the volume up button you connect your phone to your usb. It wont even show u an lg logo if that fails you try with volume down. If that fails then you will have to short circuit the phone

I was able enter download mode before I used that tool..now it just keep on bootlooping.
I think I have to try short circuit as u recommend.
Thanks for the help.

[HELP] Deadly Bricked Phone

Hello,
So eum, after ASUS released the nougat update for the ZS570KL model.. my phone automatically downloaded the update and started installing while I was playing a game, so the phone turned off without completing :c
It started on a bootloop so I tried to boot on recovery and reinstall the STOCK ROM via adb sideload since Wiping cache and Factory reset didn't help..
adb sideload didn't recognize the zip file no matter what I tried, so I went ahead and booted on fastboot and flashed recovery with TWRP and boom I guess I fried the recovery boot..
Anyway my phone is stuck on bootloop and cannot access the fastboot again nor the recovery because both redirects me the ASUS loading logo and gets stuck there (for over 24 hours)..
I somehow clicked on both UP and Down Volume + Power button, I noticed some phrases then the phone shut down.. I went ahead and plugged it, and my PC could recognize it as Qualcomm HS-USB QDLoader 9008
How do I unbrick my phone from there? I did some research but I couldn't find the necessary files to bring the phone back alive..
can anyone please help? it's the ZS570KL 2.15GHz 64GB model

I dont know if this will help but maybe u can give it a try. Off course for your own risk ok.

How did you do that ??? i have version ZS550KL, i bricked myphone.

Hey guys, I did brick my phone in a state that booting into recovery makes it bootloop as well as booting the phone normally... What I did was leaving it charging 100% then try again with fastboot by holding Volume Up and Power button, once it vibrates release the power button and keep holding the volume button till it freezes on the black splash of ASUS, the plug it to your computer and flash a TWRP recovery img (I found a working one on this forum) then boom flash your ROM like you normally would after successfully flashing your recovery image

i need help guys, i bricked my zs570kl for flashing wrong firmware. mine was the old Qualcomm HS-USB QDLoader 9008 brick (no led light if i plugged it in and it only showed on my device manager this HS-USB). i need those raw files of this phone so i can revive him again pls?

stuck on starting message screen....

So my phone was hardbricked for sometime, everytime i tried to connect to my pc it would get recognised as 900e and not 9008 no matter even when i tried using deep flash method so i updated the driver to 9008 in device manger and tried spamming the download in qfil and it flashed to 100% successfully but my phone still was dead and wouldnt turn on then after the battery went dead when connecting to the charger the phone came to life finally but here comes the present issue its stuck on your phone is unlocked and cannot be trusted and wont boot screen and would boot after 5 secs but that never happens it turns off instead i cant even go to fastboot or recovery by pressing volume buttons nothing happens if i just press power button it only shows the message only when connected to power can anyone guide me through this please its so annoying seeing nothing work for me ive went through 1000 of guides and stuff but nothing seems to work i just want to revive my phone again
