im afraid im pretty new to android ( gt540 is my first smartphone ) but anytime i updated, everything went ok, in fact yours is the first time i heard of a crash while updating so i cant give you much info but your in the right place, im sure the devs can figure something for you. just try remove the battery and then plug into your pc. and its not a problem replying just wish i could help.

well, did you try with the battery removed?

yes i did nd there is nothing

plz any one help in that

plz some one tell me how to make abootloader to it i have another lg gt540 i want to know if i can use it to repair the bootloader for this dead phone

The problem is theres noway u can acces inside the phone memory to patch bootloader. Go to lg waranty and tell them this happened when u were updating phone, dont tell them that pc crashed, tell them u updatet through lgsupport tool too, not through kdz updater they should fix it for u.

can any one tell me what should i do

Remove battery press volume - or + I can't remember try two options, then plug in usb.
You should see blue screen with DOWNLOAD or EMERGENCY MODE text.

i tried all keys combination nothing work

my mobile internet went dead after flashing quarx rom (I did it wrong btw...), but everything else worked fine.
I couldn't get mobile internet back on track no matter what (it was disabled in quick settings when I flashed quarx), I even tried factory reset and flashing the baltic rom. during the flashing, the kdz updater gave me an error close to the end, and my phone became stuck at the android screen.
even though I have CWR installed, so I could flash it again, I sent it to LG claiming I was updating through their website and since my phone doesn't start. I didn't tell them anything about the mobile internet not working. Hopefully they'll clean the phone completely and that will fix it.
I'll be picking up my phone after work today, I'll let you know how it went.

Same thing Happened to me n almost **** my pants for killing my brand new phone..
follow these steps
1. volume +or-(i dont remember) +camera n power on. it should turn on n say downloading mode.
2. update( you can use kdz updater, it probably wont crash this time but even if gets stuck just w8 for it)
3. after updating, remove the usb cable n turn on the phone, hopefully it would work
4. ENJOY ( N THINK TWICE BEFORE EFFING WITH THE PHONE, )
i am not sure about the keys for emergency/downloading mode(i think it was vol-) GOOGLE IT IF KEYS DONT WORK.

Put to microwave on 2 sec without battery and send do service

my service provider fixed my phone in 3 days without any issues, they flashed the t-mobile branded 2.1 on it. went home and now I have the open europe with fastboot and cwr.
so if all else fails, just send it to LG or your provider.
cheers!

Can't unbrick Optimus l5

Hello, I ran into a problematic brick on my L5...nothing seems to work to unbrick it.
I followed the guides step by step using the KDZ updater and the appropriate firmware for my country, but it doesn't work.
How I bricked it:
I had CM10 installed and perfectly running for a month, so today I decided to attempt an overclock to speed the device up a bit.
So, I downloaded and installed the modded kernel, flashed it using CWM and rebooted the device. After that, the device just keep booting up, showing the LG logo and then a black screen.
Now, after trying to flash the old firmware after going into download mode it just stops on the LG logo with the flare (sun ray effect) spinning around the logo all the time...It's been like that for almost 30 minutes now. I attempted re-flashing it 3 times but nothing seems to work.
What do I do?
Thank you in advance.

It's bootloop. When I had L5 I had the same problem after flashing bricked phone via KDZ.
Do hard reset with key combination. It worked for me. Phone will boot up few minutes.

This is what I get when I connect the phone by USB.
I just cant get into emergency, DIAG or emergency CS
KDZ the phone connects and then I get a message afterwards PHONE NOT FOUND.
everytime I install the drivers by LG support tool, it keeps giving me the option to install the driver, like I havent done it a hundred times over.
I think there should be a driver somewhere that can be installed but the only people that have this driver are LG tech's. So they can bill you after
send the phone in cause you rooted it. So the one billion dollar question is witch hero will find a way to unbrick this device. We only need a way
to get a driver to install and we are home free. Or maybe the only other option is throwing the phone for sale on internet for spare parts
HELP PLEASE HELP find a way to unbrick this phone. Believe me I flashed and bricked alot of different phones and there was a way out but in
with this phone it seems impossible!!
And there is no mode to put it in in because te volume buttons don't do crap, the home button also, the only time that the phone does show up is when windows tells me it has an unknown device that I for the love of god can't find a driver for. I tried SDK, the LG drivers, but no dice

Did you try emergency mode? (volume up + volume down + power button)
If not, see if you can enter it and then flashing your stock firmware with Software update [KDZ] 1.0.4.4 (KDZ-Flasher).

Download mode and LG mobile support tool not working

Hello all,
usually i deal with my problems by searching the forum, though this time i am really worried as i cant find anything to my help.
You see something went bad with the screen and because the phone is rooted, i cant get it fixed (it is still in warranty), nor can i use it (the touch sucks).
So i am trying to get it unrooted.
So i have downloaded LG mobile support tool and the drivers, i enter the phone to download mode and nothing happens. i get all the time errors. Also, in the lg mobile support tool, i see a software update. Should i do it? I cant though because the start upgrade button is greyed out, and the "LGD802" sign on the left pane is flushing like its trying to verify my g2. Also, should i wait for like 10 minutes or so when i enter download mode for the bar seen at the phone to be completed before the whole process? Lastly, the most of times the lg mobile support tool crashes on the pc.
Please help me folks... :/

the problem is when i hook my phone up the pc and it recognizes it, it starts the download drivers part but it freezes and force closes...

You will need to do some research, start on the LG website, I don't know the steps because my variant doesn't have a kdz available, believe you will need a pc, to connect the phone in download mode to flash

[Q] Any advice for bricked G2 [D802] make unbrick ?

Hi everyone, i have a G2(D802) which i have used for 5 years. Yesterday, when i turn off the screen then try to turn on it didn't. I tried to reset with holding power button like 20-25 seconds. It stucked at LG logo. After many reset nothing happened. Then this morning i could was able to open my phone, so i thought it was a problem about software things, so i backuped everything and change my rom(i was using Lineage 14.1 ) to Resurrection Remix. But same thing happened, when i turn off the screen it has gone again. So i decided to install stock rom back. But this time when i used Flash Tool 2014 and appropriate KDZ, it stacked at 4%, after trying different cables, ports,windows 7/xp and programs (like LG Mobile Support Tool, LG Up) in Device Manager it seemed as : "qualcomm hs-usb qdloader 9006" and no recovery mode no download mode, when i google this problem i found it named with "qhsusb_bulk" and i found this article and successfully recover download mode. Now in Device Manager it seems as "LGE AndroidNet USB Serial Port".
TLDR: I can only open download mode, no recovery, it stacked LG logo, when i use Flash Tool 2014 or LG Mobile Support Tool with different KDZ/TOT it stacked at 4%. What should i do? What's wrong with my phone? I need your help urgently because i have no other phone. Thank you for reading.

hi there.. unfortunately LG did a mess in my opinion! After buying G2 and G Pad I will never buy LG again because of this..
anyway, assuming you're doing everything as described into the guides (like port COM 41, copy the right DLL file etc) there is one thing I would try in your situation: trying with a different PC, in particular a Windows 7 / XP one..
also I read that sometimes this issues was randomly gone after trying and trying and trying and trying and trying..! If available I would also try different KDZ firmware (but be sure it's for your model.. as long as it is it doesn't matter if it's JB, KK or LP)

Thank you for your suggestion, after several hundred attempts i successfully go back to stock rom(an Indian stock rom which i found it in storagecow link), but the problem is; when i turn off the screen, i can not open again, and it restarts and stuck at lg logo. After hundred times reset, phone started normally, then i flash a twrp recovery (with autorec) and go recovery. This time twrp said Unable to Mount System,Storage etc. so twrp shows internal storage: 0mb and all folders(data,sdcard,system etc.) empty. I mean define this problem is very hard and i think it is very rare problem. I'm not sure which part of the phone is the problem. I don't know is this a hardware problem or a software(like wrong partition or something like that) problem.

so ROM is flashed but no files are anywhere? Did the same happens when you browse the device with the windows command Prompt / Linux Terminal?
Yea anyway weird, maybe you can see if this tool has original partitions for your model: https://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 - please pay attention if you do it and backup the partitions you have atm before

I used this tool when my phone showed in Device Manager as : "qualcomm hs-usb qdloader 9006" and it worked, today when i opened my phone(after install stock rom again) i kept the screen always open. After 5 minutes, suddenly screen gone and stuck at lg logo. Now I think that the problem is definitely hardware. Because i did nothing and phone was connected with a cable to my pc. If the solution is to change a part(like the processor) inside the phone, I will write here what the problem part is. Thank you again.

I found the problem part. It's the eMMC chip. I disassemblied the phone and heat the relevant chip (on my motherboard the chip named as Toshiba) with hot air gun. My phone worked properly for 1 minute, then gone again.

you know what: I think my device has the same issue, eMMC is damaged.. I'm not using the G2 as primary or secondary device anymore but from time to time I like to flash something and using it.. but it's almost one year that when stuff I have no error but when I boot the device and start using it I have random reboots.. but they are totally random and almost happen when installing one app, using a system app or something like that. it happens with both stock firmware both with custom ROMs.. basically I have to flash and using the device for a day and if I have less then two reboots in that period I go on..
I'm not an expert about hardware matters, do you mind linking me a video on YouTube about what have you done with the airgun? Also I tried to search for spare eMMC but I wasn't able to find any (some time ago) so the option would be to change the motherboard.. did you find something instead?

This is the video I get help with: https://www.youtube.com/watch?v=ft8V5yrQFic
this guy did this for g3 but doing for g2 also works. This is definitely a temporary solution. It works maybe just 1 minute (like me) or 1 hour if you are lucky maybe 1 month. Changing motherboard is primary solution but it is expensive and worthless. I think that is chronic problem for LG G series. There is no proper heat dissipation on the motherboard. They have just put thin metal plates. Maybe you can try after the heating process, just put a thermal pads the relevant chipsets. You can see from this video: https://www.youtube.com/watch?v=HMdvG6w7etU

I thought about applying something (couldn't imagine what however) on the internal back of the cover but not because of the issues I have but simply because the device get hot very soon! I'
But basically you are saying that this issue related to the eMMC is not because the chip is damaged but only for the temperature it reaches?

Yes, because of the eMMC chip is damaged. But the crux of the problem is processor heats and cause of no proper heat dissipation this damages other chipsets. Thermal pad solution must be done after chip replacement.
