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.

anything i can do for my phone?

some update
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

update
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...

not yet, but not abandoned the project
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

i also have exactly the same problem. after unbricking . and coming to korean firmware i tried putting at&t firmware images and in the last step. it gave me an error "less in memory " for system.img.
the battery was at 2% when i did that. since then the screen wont light up.
i am trying to see if i can charge the battery with an external charger and then put back to phone and try if it boots.. i am pretty sad about it ..

P350 not start

hello
I have a lg p350. Today i installed a wrong firmware .dkz. Is from lg p500. While doing the update give an error which is normally. After that, the phone not start, not enter in emergency mode....do not nothing. I tried all buttons. Please help. Thanks

only one way go to the lg care.

I know that ..... but maybe there is anothe rway

no other if you can't enter in emergency mode. You hard bricked your device now only lg can fix it.
Mostly lg will say you need to change PCB board which is costly

I have the same problem and I think only because of the firewall: |
I have a warranty on the phone and I had a problem appears.
What to do? There is no way that you can practice at home?

as i say if you can't enter in emergency mode then no any other way. This is 100% hard brick which can fix by only lg.

Emergency mode is the last resort for LG resurrection... If that is gone, a new PCB is the only way to go... Changing PCBs is very much like buying a new phone (besides the fact that it costs a lot, but PCB is like a PCs motherboard)...

not really but sounds like serious hardware problems. from what I know a bricked phone can usually be fixed by flashing stock firmware but you need a phone with power to do that........can you get into download mode?

I think I responded to your post in one of my threads. If you flashed an H850 firmware on to the H815 the phone is bricked. Only fix would be replacing the motherboard.

If you did flash wrong model firmware and the device shows no signs of life. Yes. Or an special box might can revive it which phone repair shops may have. But it wouldn’t be free

Please test this.
Switch Phone off, remove Battery and put back, do NOT switch on! Press and hold the Power-UP Button and connect Phone to Pc via USB. Keep the Power-UP Button pressed. Does the Phone show something ? Did it vibrated shortly too ?

If you have not triggered ARB it is possible to enforce the 9008 mode (by bridging 2 PINs) and recover:

Brick/non detected/no boot - switch motherboard ?

Hi guys,
I'd need a few phone fixing advice, I opened a previous thread (still about a LG G3 D855 16G) here : https://forum.xda-developers.com/lg-g3/help/lineageos-soft-brick-files-t3711525, bu I guess it's no more a Lineage OS related issue so I opened this thread.
Long story short, after shorting some pins, I managed to use BoardDiag. Though, after loading the last part (sbl1), I couldn't do anything. I guess I managed to "super-brick" it
I can't boot, dl mode, recovery mode, nothing, it does nothing. And when plugged, the computer don't recognise anything, it's as if I plugged a USB cable with nothing on the other side (tried with multiple cables of course...).
Any idea of what to do from here ?
I figured an option might be to just switch to another motherboard and get done with that ?
If I do change the motherboard, are there any restrictions ? I have a D855 16G, would getting a motherboard of D855 32G or F460K be fitting and have an impact on battery life ?
Thanks already!

I had the same problem so i Change the motherboard from a ls990 to vs985 that is the only solution ,, now i have a verizon device with a spring motherboard.

Yea the motherboards are inexpensive as long as its from a trusted seller Clean imei and No flickering bootloop or other known hardware issue
Easy as pie to change 15- 20 min max

I'll give it a shot :good:
