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)...

[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.

its bricked. but why how,? but well. i think you must send it back for repair. i think i have hears people telling LG that while you were upgrading using LG bridge it didnt finished and i guess they should fix it. or unless you use service like JTAG but its called diferent i think.

K10 restoring

Hi all! My K10 (K430ds) after reboot stopped turning on. The computer detects for a few seconds. Charging does not show, with the clamped key the volume up signs does not give. Any ideas how to recover?

No, does not work. Only black screen.

Take out battery. or **** on it and then dig it in the ground.

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:
