hi
i hard bricked my lg 930

i followed this step
http://www.androidauthority.com/lg-nitro-hd-clockworkmod-cwm-recovery-48447/
(do not follow)
i tried install ClockworkMod (CWM) since i installed the koereean rom and (no wi-fi to install tru rom manager)
is anything i can do for my phone like i'm not able to go in download mode, i can't see anything on screen. black
while i connect the usb cable i can hear a sound like connecting to computer
thanks a lot

We would need some more information to know if your phone is truly bricked.
does your device show up via ADB?
does it show up with B2CAppSetup program?
have you followed the unbricking solution?
http://forum.xda-developers.com/showthread.php?t=1597488
an important part of getting the phone into download mode is unplugging the usb at the right time during a hard reboot with the volume up held.
hope any of this helps but hopefully we will hear back with more info.

first of all thanks for response
no, it doesn't show up in adb (use command adb devices)
i can hear only the sound from computer (exactly like you connect true usb cable) but nothing on screen
yes, i tried the steps but ask to connect the phone, no usb connecting

@Maverick.Marq,
No, we don't really need more info to know his phone is hosed. Basically he has flashed a supposed CWM image on top of one of the bootloader partitions instead of the recovery partition. Everyone should contact these guys and tell them their guide is horribly, horribly wrong. They never responded to my email...but maybe if more people contact them about it, they'll remove their stupid guide.

some update
i have 2 computers
to the first one i never installed phone drivers other then lg drivers
1- in device manager with the phone conected (without or with battery) it's show "QHSUSB_DLOAD" with exclamation , see attachment
error 2 device manager lg p930 nitro.jpg
error device manager driver lg p930.jpg
2 - in USBVIEW20.exe when i open (phone still conected) i have this error (see attachment "error in usb view.jpg" and "usb view qualcomn.jpg")

some udate 2
in second computer i had many phone drivers like sony xperia play, htc evo 3d or htc desire
it's show zeus flash device with exclamation and now QHSUSB_DLOAD like the other computer - see " error desktop device manager zeus flash device"
i made 2 posts because i can't upload more then 4 images
i think to force to take driver for QHSUSB_DLOAD but how can i do that because i tried with propietes, update driver and don't want to take " android_winusb.inf" from lg drivers
i found in adb/adroid-sdk/extras/google a file android_winusb.inf and i have 3 choises (of course, i try to force to take the drivers,)
sorry for my english
if is some developer i can give access to my computer by remote
any ideas
thanks

i tried to burn the recovery image with nero and i have a error size
maybe this was the problem, the recovery image was incomplete?

LOL, I have no idea why you're trying to use Nero, but yes you are correct -- recovery images should be 16MB (16777216 bytes).
That's not the issue though. The issue is that you flashed something to the mmcblk0p6 partition, which is bad.

i used nero just to see if is some error
mmcblk0p6 partition it's the bootloader partition?

Hi
Hi Nickmatine,
Could you please confirm if your phone (LG P930) got unbricked?
Regards

@allians2002,
Unless he sent it in to be hardware-flashed, it's probably pretty much hosed.

I think I have the same problem
http://forum.xda-developers.com/showthread.php?t=1569514
There is nothing you can do. I will sell mine, or if someone need a new screen or something, just so damn unlucky...

i think know where to solder wires to hard flash but it's a very small connector. Maybe 7-8 hours just to solder the wires. If someone know where can i buy the cable for this connector i can help you and other people

Hard Bricked G3 - no fastboot no recovery pc cant see my phone

Hi, today i installed android 6.0 on my g3 d855 then rooted it and i tried to flash recovery with AutoRec from google play, but unfortunately it was only for 5.0 so i rebooted phone and it.. just didn't wake up. Now my phone is showing lg logo sometimes. I can't get into download mode and my pc can't even see my g3. When i plug my phone with battery in it pc doesn't see phone but when i take out the baterry in devices manager i see " unknown usb device (device descriptor request failed) " . What the heck am i supposed to do? Searching for the solution for 8hrs and still nothing.

a. yes, this exact blue points
b. just those 2 pins! connect between them, and while they are connected, connect the USB. (you'll probably need a 2nd person help to that, unless you are very skilled with your hands)
c. i don't think any repair store will get to that level, but i don't know the level of support at your country... also, the process is pretty simple, took me about 2 hours of work to get my phone from really hard brick to fully functional rooted CM device
d. i don't know about MM tots... i would suggest using this guide: http://open-freax.fr/guide-unbrick-your-lg-g3/ it worked for me and many others for sure! it provides you all the files you need. just make sure you have efs backup or at least know your IMEI number (which suppose to be on a sticker under your battery)

Also try another cable, 2 months ago I tried it, was sure I did everything correct but nothing...changed cable and boom

I have the IMEI on the phone box, i don t have any EFS backup, but i don´t think i can do it.
Wait, found something in my SDCard, i remember i did it time ago, this is the backup?

yep. this suppose to be the backup i was talking about!
but if you have your IMEI number so everything is good anyway,
you can go ahead with this guide: http://open-freax.fr/guide-unbrick-your-lg-g3/
i'm sure you can do it, just read it carefully before you begin and do exactly as it sais

I actually grounded at a common ground point the main pin is the upper pin if im not mistaken but i did ground to the frame makes it a hell of a lot easier and i used anlong piece of small gauge speaker wire frayed back with about 4 or 5 strands of copper and if i. Not mistaken u must use firmware tot that u were on before brick

I´ve soldered an "connector" to fix a side at ground and the other side a needle to exactly point the pin. "Connector"
And here´s the pin which must be pinned: Here is the Pin
And if you are opening your G3, just a few screws more and you can fix your temparatures: Tutorial with Video

I also reccomend the thermal mod i record at least 10 to 15 degree cooler temps your rite there any ways

Hi there, I'm in a similar situation: I shorted that pin with GND and tried to flash through BoardDiag (I followed this guide). That's a problem. Before I had this issue, I had a fully working stock KitKat (I flashed the tot with LG Flash Tool) but I made some mistakes and tried to wipe through TWRP and to install other ROM (here's my thread). My phone died. I just think that the problem is with the TOT I am trying to flash with BoardDiag.
My D855 is currently with black screen and no led blinking (only QDLoader 9008 mode).
Any help? Thanks and happy New Year.

[Urgent] Bricked G3 D855

So my G3 16gb version just got bricked..
I had CM13 on it and it just shut down on me, I've had roms since the first day on this smartphone.
So I turned it back on (had to remove the battery), but then I realized that the screen was all black but the smartphone was still on... (weird)
So I took the battery off and waited for it to start and like after 1-2 minutes it just went black but the screen was still on.
Now it doesnt boot into TWRP, or download mode.
If i try to enter download mode, it just shows the LG logo, and after 5-7 minutes the download icon appears then goes to fastboot
If I just turn it on like if it wasnt bricked its stuck at the LG logo..
What can I do? I tried the KDZ flash but since I have no download mode I can't use it..
I also saw this link and didnt help me https://www.reddit.com/r/LGG3/comments/2qe5sr/in_need_of_serious_help_stuck_in_fastbootno/
The only thing that i havent tried was this method: http://forum.xda-developers.com/spr...y-download-t3053985/post60106965#post60106965
And the pin shortening one..
Theres nothing on COMs before anyone asks...
Please help me
EDIT: Downloaded files from here http://downloads.codefi.re/autoprime/LG/LG_G3/D855/stock_partitions/10A_16G and tried flashing with this guide http://forum.xda-developers.com/spr...y-download-t3053985/post60106965#post60106965
No luck, it gave me a bunch of errors writing to the memory : http://pastebin.com/raw/dMRvsnXr

If you did nothing to brick it then it is a hardware failure (eMMC is dead).

Nah.. cm13 and emmc bug = known
Check the cm13 forum. Can be fixed no worries. Basically d855 I unbreakable as I discovered lately.

Might be a bug that is right but trust me if you eMMC breaks and you can't download to it, it is a hardware problem.

Sure. But on the d855 there is a way out. By activating the USB quality 9008 mode. With the wire trick. So it's bricked, but it can be rescued.

No you get it wrong. It's 2 different things. If you brick and your eMMC is fine, yes you can go to 9008. If you eMMC is damaged you can still go to 9008 but it will fail to write on eMMC and fail to recognize it.

I understand. But this error is known to happen with cm13. So nothing broken I would say. Had it all ready 2 time on cm13 never happened with stock based or cm12 for that matter.

LG G3 wont turn on

Hi everyone
I having this problem with my lg g3 d855 ... My phone was at 5% then i wanted to remove kingroot because i wanted to flash super su. After uninstalling kingroot (in the app) the app crashed ant after few seconds my phone turned off... i was thinking my phones battery just died, but i was wrong. My phone wont turn on now :/... Only response i get from it then i plug it in the charger without battery (it show no battery error)... then i put battery in, screen goes blank.
And also i installed twrp using app from store (Forgot the name, but for d855 model)
*LG G3 D855 Android 6.0 official* (if needed.)
i tried:
holding power button for 15sec without battery and then charging it... Didn't work :/.
Putting another battery (Galaxy s3... Charged to 30% at least. I don't have another lg battery ), same result.
New battery also doesn't do anything...

And Thanks for replay

I was in the middle of unbrick my g3 from hard brick to soft brick. I flash firmware using lg up at 99% then the phone died as it tried to reboot. It won't boot at all. As you said when remove the battery and connect charger, i can see my motherboard working with exclamation mark. As soon as i put the battery, motherboard out and no sign of life. Is this sign of bad battery or what. I don't have spared battery

I recommend first, to users with similar problems, to try first my guide in following link and after the pins in motherboard-tot files

LG G3 not responding ( no boot, no download mode, nothing)

I was hoping someone here could offer me some guidance on what to do.
I've got a LG G3 D855 (international)
So I tried putting TWRP on my phone as a recovery but I must have done something wrong.
My phone isn't booting at all. It's not even responding to putting a usb cable in. Only if I connect it to a usb cable without battery it shows the logo that I don't have a battery inserted.
Did I completely destroy my phone?

I think you flashed the recovery image as boot image. Get the boot.img from your original Rom and flash it as boot image in recovery.

The phone didn't make a connection to my computer and was not recognized by fastboot, etc.
But I've just received it back from the store and they repaired it.
Thanks for the help!
