Lg optimus one died

Please help, my LG Optimus One won't even start anymore - I was using KDZ Updater and an error came up, I turned it off and tried to turn it back on, but nothing happens - it doesn't do anything, I press the button and nothing happens.

Take it to the warranty service. Tell them that you tried to update the firmware via official lg tool and something went wrong.

I cant help u out in this situation u should contact to LG but prefer u that in future if u faced any of this situation dont disconnect ur phone in EMERGENCY MODE, if in case of any error while updating or downgrading then at the same time restart KDZ Updater and flash ur phone with a working rom.

Anyone have any other fixes for this? Can't send back to LG as I bought it off eBay.

- don't worry , stay calm i brick'ed my phone like 50 times, i brick'ed so bad it diden't want to start, power button was usless.
TRY this:
- remove battery , while holding the UP volume key and back button connect it to PC via USB Emergency mode should apear , then open KDZ and install via 3GQCT and EMERGENCY an original/stock firmware ( Froyo 2.2.2 v10E.kdz http://www.4shared.com/file/O3Nw1b4s/V10E_00.html )
- after KDZ finishes an animation will apear , then you must put back the battery.
- things that you may encounter , errors in KDZ , phone fails to start after KDZ resets it , KDZ successfully installs rom and powers off phone when you power on phone it stopps at Android logo, sometimes the android logo animation work's and lags for 2 3 seconds (do a battery pull, put it back then power on the phone if it lags then you must reflash) , you must do a battery pull, connect usb without battery and chose DIAG in KDZ, reflash. ​
- as i was saying i killed my phone alot of times, KDZ always helped me bring it back to life , be patient.. and if you get alot of errors and flash meny times the phone gets hot , leave it to cool for a while and then try again.
you can install Froyo 2.2.2 v10E.kdz

You should hold both buttons by one hand using 2 fingers and simultaneously connect it to pc through usb cable to enter into emergency mode..its a bit tricky..just by only pressing two button nothing will happen.

Nothing happens. Can I try anything else before I take it to LG Service Center?
P.S: Removed the URLs as XDA would not allow me to post.

Just go to the service, i had this problem twice , but i just go to the LG service and they changed my phone mainboard

Yeah. That's what they said to me too. Will be a week without my phone now.

well my warranty has been over
so normally send to service center they will charge right ?
furthermore, almost everytime flash to v20g (gingerbread official ROM) my phone sure can't turn on
so flash back to v10g (froyo official ROM) then said something param error, and my phone matter how I turn on also black screen
which either turn on in emergency mode (back + volume up + power), factory reset (volume down + home + power) and normal turn on phone
try charge the phone also no respond

Refer this THREAD..!!
Might help.

tried already
as I said can't even turn on into emergency mode

Then you have no other choice then to go to LG Service Center.
Find one with JTAG.. it will cost you less. Otherwise it will be costly!!

what is JTAG ? mind explain ?
and my warranty has been over
they normally will charge right ?

I will explain you in a simple way.. when you do a hard brick, you actually corrupt the IC data.
The main IC ( processor) on the board is a programmed one. (We used to program basic 8085 and 8086 processors which used to be a big pain).
So when you hard brick a device.. there is no other option than to change the board (PCB).
But if there is someone well experinced with JTAG.. they can reset and re-program it again.
And it will cost you less than replacing the board.
Not all Service Centre do JTAG though.. hope you find one!!
Yes.. they will charge you!!

did ur fone goes to offline charging mode still?? if yes playing a little wid kdz updater can bring ur fone bak. if nt go for service cntres.

It downloaded 430 mb file and installed the firmware and said completed , but when i powered on the phone i got LG logo and later T world logo like the logo which is on the back pannel and colours changing all the time like a pattern and it was like that for 30 - 40 mins later the screen went lack but all there buttons at the bottom , home entrer and options were illuminated .... no android OS .....
I? tried to recover the phone again via LG software but did not help same result , i am really seperate to get the phone working as it's my first android phone in my life , i really wanted to use it but now i cannot ....
also on all over the internet they talk about o3d p920 and not 03d su760 ...
Please can someone tell me where to find su760 stock firmware and how do i flash it to the lg phone ,,, i cannot even enter hard reset mode using volume key combination and home and power button ,,, seems phone is stuck in a cycle .... please HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!

For Hard Reset try this
remove your usb cable
remove your battery
insert battery again
press and hold volume down button
press power button
(you dont have to press 3D button thats for CWM Recovery)
(you also dont have to press the Home button)
after 8-10 seconds it will show you LG logo
release the power button and then the volume button
It will take you to the recovery menu
select yes
then again wipe EVERYTHING
ALL 4 OPTIONS
you can move with volume up and down and with menu key you run the commands
Good Luck

oh sorry i did not use samsung toll its a mistake i used lg update tool ...
xbsall : I tried with volume down and power , but no recovery menu .....

try volume UP and power, sometimes it needs to try several times to get in the CWM.
and its very crucial to do the fully wiping.
i wipe everything before the flashing and after.

i tried volume up and power still nothing ......
Where can i get stock firmware for su760 .....
all sites have it for p920 .........

Step 1
download
SU760 V20E ROM from here:
http://csmg.lgmobile.com:9002/swdata/WEBSW/LGSU760/ASKTDB/V20e_00/V20E_00.kdz
Step 2
download this
http://forum.xda-developers.com/attachment.php?attachmentid=887870&d=1328537753
Step 3
make sure you have installed your lg phone drivers before continuing to the next step
Step 4
unzip LG_KDZ_FW-Update_OfflineFix.zip
you will find a filename Automatic Offline Procedure.vbs
run it
if everything runs ok it will take you to the upgrade tool if not it will probably show you a windows script host error
if that happens try running it manualy from folder
LG_KDZ_FW-Update_OfflineFix
KDZ_FW_UPD_EN
KDZ_FW_UPD.exe
when KDZ_FW_UPD.exe shows up select Type: 3qct and PhoneMode: Emergency
select your downloaded kdz file , now you should take off you battery , connect the usb cable , press volume up and power button and after 5-6 sec release the buttons and put the batery
Press Launch software update
It will take some time to decompress the files but if everything is ok it will start.
You will see the progress with various messages the last message ends with 0
That should do the job.. Dont forget to press Thanx button if it works.
Good Luck

xsball : thank for a detailed guide , i tried to flash the phone but , the lg flash tool hangs up (not responding)
So i decided to give the phone to LG they are going to fix it or give me a replacement until ...
but thank you for guide maybe it's my computer that is not working properly ....

The KDZ tool needs to run from a Win XP environment. That's how I managed to downgrade my LU620 (also from Korea.)
I've tried over and over to run the program on win 7 but it almost always crashes...

i will try from XP and let you know

xsball : i have used windows XP and followed all steps but still LG R&D tool hangs on xp aswell can i use another 3rd party tool ...... ?

if your phone doesnt start put it in download mode like Trekfan422991 does in here (this is p920 but try it might work)

XSball : first thank you for the video , i tried again still no luck also i put it in SW download mode still no luck ....
even formatted my PC did clean install of XP still no luck ...
i can try lg flash tool and making custom usb cable by soldering resistor on cable , but i dont know wher to find su760 bin file ...
or last resource is to send the phone to LG and get it fixed ...

beore you start soldering open a teamviewer session and send me a pm..

http://www.lgmobile.co.kr/mobile-phone/U760/LG-SU760
This is the model number , but sure thing i will PM you and then we can run team viewer session and see what went wrong ...

Don't pay to service centre ever without knowing what you are paying for. In most cases when your phone is dead, ur motherboard has minor damage. so they should take 1500 inr for that. but in case the motherboard is burnt then 8000 for whole of it. I have paid once so I know about this

Glad everything worked out for you. Having once worked for a phone repair center, I can tell you that replacing the motherboard or other hardware is standard procedure. It's all about minimizing turnaround time and maximizing profit. Replacing the hardware is cheaper (for the service center) than spending time trying to troubleshoot the problem. That's why I tell people that unless they're sure it's a hardware problem, it's usually better to just learn how to fix their phones themselves.

OT..
Minor or major.. anything happens to board cant be repaired and has to be replaced. Everything is fabricated using computerized tools so a normal person cant repair it using a soldering iron.
Anything that is not on Pcb can be detached and replaced.
If the phone is hard bricked.. there are only two options
-Replace the board.. which is costly.
-Find a service centre with JTAG to reset and reprogrammed the IC.. lot cheaper than replacing the board.. but hard to find

LG Optimus G stuck on boot logo

Ok so after many a month of wanting to finally get 4.2.2 onto my device I finally tried today(since lg doesn't try to update their flagships). After finally thinking i got it by using FreeGee and supposedly unlocking the boot loader i boot into recovery only to find out my phone has been softbricked. I have looked everywhere and can find no possible solution to fix my phone.
PLEASE I will pay someone $10 paypal if they help me fix this.
Some info
-I CAN enter download mode
-factory reset mode no longer works and only makes audible usb "dings" on my computer when holding down the vol down + power buttons.
-If i try to turn phone off by holding power button it reboots 3 seconds later to the LG logo and sits there.
I will have this forum post open 24/7 so please if you can help me, kudos and $10 to you.

Basically you need to enter download mode and flash install a rom and then revert to factory rom, or restore using the lg update tool. Use the search bar and type any of the following phrases lg optimus g restore with lg update tool restore lg optimus g or just go to the lg optimus g forum and browse

Lg g Stylo, "no command" please help me!

Please guys I need your help!
Phone model: Lg G Stylo h631 T-Mobile version.
Today I was using my phone and after finishing a call, my phone started to update itself. Then I received a error message. After that, I get stuck with a dead android guy on the screen, and I get the message "no command". I try Different combinations of buttons to solve this problem: Volume Down + Power release and then press the buttons again went the LG logo appear and have no luck. Then I try Volume Up + Power, also have no luck. I think I try almost every possible combination an nothing is working.
If anyone has any idea how to solve this issue please help me. Any help would be appreciated.
(Sorry for my bad English)

Make sure you download or have downloaded and installed the LG drivers from the LG website or any other reliable source or your phone will not be able to recover.
Unplug the phone, take out the battery and once the phone is completely off, replace the battery. Keep the phone powered off and unplugged. Plug a data capable (the usb that came with the phone is best) usb into a PC. Press the VOLUME UP button and HOLD it WHILE plugging the usb into your phone, (The PC should already be connected before plugging in the phone) continue to hold the VOLUME UP button until you pass the LG splash screen and you should then be in DOWNLOAD MODE. From there you can reflash the stock ROM that came with the phone. The stock ROMs are pretty easy to find here on XDA.
If you don't know what flashing a ROM is or means then XDA has plenty of guides for that as well. To return to stock you will need the LG Flash Tool or LG UP depending on which version you want to flash. Marshmalllow uses the LG UP program and Lollipop uses the LG Flash Tool. You can find guides and all the tools\software you will need to fix your phone right here on XDA or a little Google searching.
