Dead Lg G3

So I bought a used G3 knowing about the issue it had; it didn't boot. I thought I could find a workaround to this but the phone doesn't boot, doesn't enter recovery or download mode. All the info I have is that when I take off the battery the pc sees it as an unknown device, while it's connected I press the power button for several seconds and it disconnects from the pc, reconnects after several more seconds of pressing the power button. Screen remains dead. Seller told me he had a perfectly working phone before he tried to root it and it never turned on again. One more indication is that the LED notification only flashed red a few times when I connected it to the wall charger and that was it. No LED working after that. I'm open to any suggestions though I guess I'm here for someone to tell me there's no hope reviving the device. Thanks in advance!

Same proble with mine but i bricked mines when update to lollipop and never turn on again . still waiting to some one help to revive my LG

If I come across any solution I'll post it here. In the meantime I've tried the following method on a freshly formatted laptop and I still get "Unknown Device" in Device Manager..
http://forum.xda-developers.com/showthread.php?t=2785089

same here
same problem, someone told me that if was the board or something like that and that it only can be fixed with a complete replacement of this, also, that it could be fixed with linux using comands to install .APK or .TOT.
linux sometimes sees it as Qualcomm CDMA Technologies MSM QHSUSB_BULK, using a virtual machine of linux ubuntu, windows 8.1 sees it as unknow device
LG dead since 3 months ago.................. i wasnt using the phone at all when this happended so........... :crying:

I tried using a boot usb drive to see if ubuntu saw the device but it didn't. Maybe there's some things needed that I didn't do. The thing I don't understand the most is why do windows see it as an unknown device only with the battery out while if I connect the G3 with the battery on, it doesn't show anything on device manager..

Hi there.
Please check these 2 threads out and see if any of it will help you. The one for the G2 can also be used for G3.
Here are the links:
http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091 With this technique you would have to find the software online somewhere but this method does revive dead G3 with these symptoms.

If I helped somehow, hit the THANKS button.
Good luck!

The thing is I can only get the device to be recognized as an Unknown Device in Device Manager and only with its battery out. If I keep 'volume up' pressed nothing happens, it's only shown after I simply connect the USB cable and it pops up after 10 seconds or so. It's very consistent in the way it behaves..

A small update, sometimes when I pull and put the battery again, I connect the phone to a pc while holding down vol- and the pc makes the connected usb sound while the phone led is blinking red for a couple of minutes, then it stops. That's about all there is concerning the phone giving signs of life..

Oneplus 3 just died out of no where

So i was using my phone and decided to restart it after updating my adaway files but my phone never turned back on. The two press the power button screens did not show up either. I tried to uses the MSMdownload tool since i thought my phone was somehow bricked but that didnt work either, it just kept restarting the download process after everything was completed. my computer makes a sound when its connected and it connects correctly as a quallcomm 9008 device but even after all this nothing is working. has anyone experienced something like this or does anyone have any advice?

did you try to long press both power button and vol up ...you should feel a vibration...
maybe it's not turned of maybe it's error causing the screen to be off... also is there any heat?

Which method of the unbrick tool did you use? First or second? If the first, then maybe you should give the second also a try.

I've tried everything and I used th me second method yet nothing happened. I can see my phone get recognized by the computer and get listed on the MSN device list yet nothing happens after it finishes the process. After the green line shows up telling me that it's completed everything the process restarts writhing a few minutes unless I unplug it. No vibration no nothing the phone just died on me after I restarted it .

Try doing MSM on a different PC with all drivers installed , hope it helps

Try to repeat flashing again, there is no other way. Use method 2only. Extract tool again and try flash.

When I was used Xperia Z1, I bricked my phone with a soft brick. So I installed driver in my PC and flash Kernel though FASTBOOT(ADB) either it's not show Device in my PC (I show just "Unknown Device").
After that my phone can connect to my PC again (Now It shown C9303 or something that meant it know it's a phone).
So I can flash by Flashtools again. Soft brick is not scary as Hard brick, you'll find some way to bring it back easily.
Hope this help!
PS. Bricked Phone is WEAK in Battery, always connect it with charger.

Vibe P1A42 stuck at Lenovo logo bootloop

Hello Guys,
My Lenovo P1A42 is stuck in Lenovo logo bootloop.
I tried to flash the stock rom "P1a42_S288_160721_ROW_RAW_QFIL" with QFIL.
So with QFIL, I see the Qualcomm HS-USB QDLoader 9008 (COM3).
I select "P1a42_S288_160721_ROW_RAW_QFIL\prog_emmc_firehose_8936.mbn" for programmer path.
I select build "P1a42_S288_160721_ROW_RAW_QFIL"
I also select rawprogram0.xml and patch0.xml.
It takes about 10 minutes to download and in the end "Download succeed. Finish download" message appears.
After this step, I press power+vol up+vol down together for around 12 secs to let the phone start with the downloaded new rom but again the phone goes to lenovo logo bootloop.
I have been continuosly searching for the solution but I still could not find it.
Probably I am missing a very small detail.
Can somebody please help me with this problem?
Thanks in advance.
Regards.

After a lot of trials I could solve the problem, but I dont know what I did different.
I did everything the same.
Anyway thanks to everybody who read.
Regards.

Please follow Getting Ready and Flashing ROM from the link https://forum.xda-developers.com/vibe-p1/development/qpst-flashing-vibeui-3-1-s272-rom-t3386650 . Once Success, The system/Phone reboots itself, You need not hold any combination of keys to reboot
Primarily make sure Your PC?Laptop detects QComm Driver when you Hold Vol Up+USB. If the device is detected and Driver not installed, You can install the same from the above link.
Verify the above using Device manager.

Dear pavanpilot94,
Thank you for your message.
I had already made the procedure following the instructions in the link you sent to me. In the end of the download "Download succeed. Finish download" message appeared, but it did not restart automatically.
That is why as mentioned in the instructions you sent; ("If "ready" message appears and device does not go to reboot, then hold Volume UP + Power buttons for ~12 sec.")), I had to make the key combination.
But everytime the device went to reboot the old Android in the device, so flashing was not successful.
I do not know where the problem was. After many trials, I could flash successfully, but everytime I had to do the same things. I did not make anything different.
Anyway the problem is solved now, but next time flashing, I do not know how to avoid this problem.
Thank you very much.

I now understand very clearly hagiwatt,
I'm happy that Device is back!!! :good::good::highfive:
On a Guess from the above understood there might be corrupt emmc locations, For this to be verified we might have to format the entire emmc. I'm too stuck with Logo Screen now, Unfortunately my Device is not getting detected by the Computer(Qcomm QDLoader) to have it flashed.
Trying to Fix it, I did a entire Format & Verified any Bad sectors as suggested by one of the developer, Unfortunately still not able to get the device detected.

I struggled for it since I wanted to send the device to warranity for vibration problem. I am happy that I could flash with the raw rom. I also wanted to reset the binary counter but no way.
Triangle Away does not support Lenovo.
I hope they are not checking the binary counter in the service center.
Does anyone have an experience about it?
Thanks.

Hi Everybody!
I have just recieved the phone from service center. They fixed the vibration problem under warranity.
So binary counter did not affect the warranity status.
I dont know if they checked the counter or not.
For information to anyone who has the same issue.
Regards.

Bricked Device-Can't make it work

Hi!
I Have a problem with my wife's OnePlus 3:
It is an OnePlus 3 64 gb with bootloader unlocked. It remained without battery, shutted down and when it was plugged again in the charger, hothing happened.
I swapped her motherboard in my phone and the issue is the same so i am excluding a battery issue. I plugged the phone in my pc and in control panel it appears like in the photo that I will attach below. It did not let me install any driver, the driver was automatically installed. I followed the guide for OnePlus 3 and downloaded "OnePlus3_Unbrick_Tool_Mini_androidbrick". The process was ok, it finalized with a green message but the phone is still dead. It disconnects and when I try to power it up nothing happens. If I connect it again, in control Panel it appears again like QDLoader 9008.
What am I doing wrong??
Thank you!

Happend to me a few days ago also had Qualcomm HS-USB QDLoader 9008' in device manager,
restored it whit this guide:
https://forums.oneplus.com/threads/guide-oneplus-3-3t-unbrick.531047/
Download what they tell you to and start from step 9, also ignore step 14.

I did it now. Followed all the steps and still no image on the screen, no leds turning on. The screen is fine, I tested it with my board.
What can be wrong with this phone??

You said that you swapped the board but your conclussion is that the battery is not the problem.
I'm very confused with that statement.

try hard bricked full tool, i done it with mini but only succeeded by full tool

Agreed. I had successfully restored the phone using the method 2 mentioned by Naman Bhalla in his XDA thread. For some people, it required multiple attempts with method 2 though I succeeded in the first attempt.:fingers-crossed:

I managed to do every step correctly.
However at the end after the MSM tool finished, I unplugged my phone and it went to boot up, but I got this message:

Can u get to fastboot screen?

Oneplus 5t black screen unbricktool doesnt seem to work

I've got a dead oneplus 5t from my son. It was not charging anymore.. So I've replaced charging cable and battery.. Seemed to work it was charging... However it doesn't boot... No logo screen screen stays black/blank.
Tried several suggestions on this forum to get into recovery mode, fastboot mode... But still nothing. Only vibrating works after a few seconds.
So tried to unbrick with OP5T_Unbrick_tool_dumpling_43_J.40_181105(OOS.5.1.7) and the qualcomdrivers..
I was able to install the drivers and I see they are installed in devicemanagement.. and an empty folder create for oneplus.
I charged the phone all night and was able to download the upgrade. It then says download complete and I tried to restart the phone..
Still just vibrating but nothing happens.. Seems like everything has vanished from the phone, no recovery, no bootloader, no files.
So how to proceed to get all the stuff on the phone? And maybe the displayscreen is dead, but how can I tell?
Also tried the SMT upgrade. Strange thing is the device and com port are seen in devicemanagement and active when I connect without volume up, but cannot start because it says When I try to use smt mode the program says: "This COM port is disable by user". With volume button up pressed and then connect, ledlight turns green but the qualcomdevice is grayed out in devicemanagement and it says waiting for device..
Any help is welcome. I am a noob in how to proceed on the phone however I have an IT background.
Spent already so many time figuring out .. maybe it's effortless and its for the trashbin.
Thanks in advance

SOLVED
I opened the phone again loosened all those tiny connections to battery, screen,charger, mainboard and re-attached them.. Somehow a connection seemed to be fitting allright as yI looked at it, but apparently wasn't :good:
