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.

- 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..!!

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

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.

[Q] Possible Bricked P920 (Stuck on Boot) [SOLVED]

Hey there,
In a bit of a dilemma here with my phone.
I was running the XBSA V21E Gingerbread with ICS Theme ROM with the TitanKernel V0.4.2 V21D 09-04-2012.
I decided to install I a new rom without a flash, The Promethius Project V1.4 followed with he latest Promethius Kernel. All went successfully with no errors, according the the boot anyway.
ok...after trying to reboot many times, I have not been able to get any further than the 'LG Boot Logo' I left it on last night as I couldn't be bothered trying to fix it at the time and it stayed on the logo for over 7 hours. (Figured it would nonetheless)
These are the steps that I have tried, of which wont work for me:
1 - Turn off your phone
2 - Press power and volume down until the LG logo apears.
3 - Release the power button but keep the volume down pressed.
This takes you to the recovery screen.
1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
4) Pressing Vol.up + power 6-7 seconde wait for the LG logo and The screen turns off
5) Again pressing Vol.up + power 6-7 seconde and wait until the drivers are installed (LG Mobile update detects your phone and the screen is always off)
6) Click on User/Support then emergency mode, insert your IMEI and click on check - I get a popup saying "Please Check Phone Information Again"
Iv'e done everything with and without the battery in place, I have removed sim and SD card.
Any help would be greatly appreciated.
Kind Regards.
EDIT: Solved!!....huh? How?.... Well my lesson learned is, flash before installing a rom....[GUIDE] Recovering from brick/bootloop
Worked for me anyway

if the case is stuck on LG logo, go to CWM menus, wipe all and reinstall the ROM, install it twice, reboot. (always work for me if I got stuck on LG logo).
sorry for my bad english.

I mentioned that I can't get to the menu in my post.

ow sorry, I didn't notice that you can't go back to CWM menus also.
you are using LG Mobile Support Tool right for recovering?
If not, download LG Mobile Support Tool and run.
- Change Country in Option&Help, select country.
- Download the usb driver, if you are not installed yet.
- Take off your battery
- Connect the phone while holding vol.up and wait until LG support tool detect your phone
- If it connected, go to Customer Support and select Recovery Phone
- insert your IMEI, ok
- wait until it finish downloading and recovery your phone.
If not succeed on downloading, try install PC suite first and redo the steps.
Hope it's work.

I don't mean to be rude, but did you read my post at all? I mentioned that I can't do that either.
1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
4) Pressing Vol.up + power 6-7 seconde wait for the LG logo and The screen turns off
5) Again pressing Vol.up + power 6-7 seconde and wait until the drivers are installed (LG Mobile update detects your phone and the screen is always off)

Ok. Tnx ..

You can remove the battery IF YOU WERE FLASHING BASEBAND ONLY
then put battery back and press vol up + back + power and phone will go in emergency mode
disable all lg modems in device manager, then flash baseband again and it will work

I remove battery ~10 times, and phone always automatticly go in emergency mode when i back up battery, but device is not recognize by tool like a LGMDP-v1.5, lg studio kdz updater on computer.

1. remove battery
2. put battery back
3. press power button+ volume up button + back button together
4. keep buttons pressed and phone will go in emergency mode
5. now lgmdp will recognize device

@TheAndroidGeek

Disable modem drivers (LG) in Device manager!

In Device Manager is disabled only LGE Virtual Modem because he is only there. But error is still there in lgmdp.

I back phone in life with this tutorial: http://forum.xda-developers.com/showthread.php?t=1197111
Thanks to xzet2 for that tutorial.
Now, i installed this ROM: http://forum.xda-developers.com/showthread.php?t=1818219
But i dont have service again (no signal - baseband is unknown). With android 2.2.2. is all ok (have service, baseband v10e is show and all work ok) but i want ics.
I trie to flash baseband to P500-v20G but lgmdp dont see phone when this ics rom installed. When installed android 2.2.2 lgmdp see phone.
In Device manager LGE Virtual Modem is disabled.
What to do?
Does ok to install ROM with android 2.2.2 and then flash baseband on v20g version and then install ics, or what?

And again hoooo ...
I start phone in emergency mode, run lgmdp and flash baseband. That all work 10 seconds, and wala ... now i have new baseband and ics rom.
Thanks!

1. KDZ UPDATE : I TRIED V20D.00.KDZ FILE . it show " upgrade error error code =6" .
( tried all three mode " DIAG, EMERGENCY, CS_EMERGENCY) but got same error for all the mode option.
2. lgmdp : upon connecting doesnt shows any thing in NV backup .

[Q] ICS omap4430 installing

Hello,
Iam running on ICS, and i want to get back to GB. When i am connecting my phone, its connecting and disconnecting fast but i am able to install drivers in device manager. After successfuly install it says that device is disconnected.. Any ideas ?
EDIT:
Now, after install there is still "connect/disconnect" USB sound, but it seems that drivers are installed.

Did you enter "S/W upgrade" mode ??
Hit Thanks Button If I Helped

I dont know how its called but i am doing this without inserted battery

No ,, you must enter S/W upgrade mode (by insert the battery while you hold vol+) then some thing will apper on the screen (tow arrows like the sync symbol) this will make your phone still connected with your pc .

Have you installed OMAP drivers properly?
Open Device Manager on your PC and search for OMAP4430 (it connects and disconnects continuously) so, quickly double click on it and chose update driver. Select browse my computer for driver software > then go to usb_drv_windows folder in OS_HACKING tool then press Next. Wait till the driver installs.
After that, run the AIO Tool and follow onscreen instructions. You should now be able to enter Fastboot mode and flash your phone.

Dear Bro!
I've flashed, unbrick, made my Lg p920 dualboot several times before but now I have problem and need u advice.
Yesterday, when I was playing a game it suddenly turn off, and turn on to the lg logo and go off. At the first time I just think its the error came from the game so I tried to press power button to turn it on but no success.
After awhile I plug power cable in and the phone turned on and boot smoothly in to the ICS, but this time I realize that power button is not function anymore.
Up to now, My phone is:
Power button dont work.
If I want to turn it on I must plug the power cable in and It boot completely to the ICS(when I put in battery the phone is wake up and boot to lg logo and go off).
I tried to install Omap driver several time but no success, There isnt Lg United Mobile port in device manager to change the port to com41.
I cant boot in to flashmode to flash but can go to TWRP (via a software in android - restart to TWRP option)
My power button physically situation is good (I mode build.pro to wake my phone up by camera button 2 years ago and it work well up to now with no problem) Therefore, I think the problems should be errors in bootloader or kernel , xloader so I think if I could flash them via TWRP may be solve.
Could u please help me?

XDA member Zogu made a thread quite a while ago. Here it is:

There you will find Wkpark's bootloader as a flashable zip that you can flash in TWRP. You said that you are an experienced user so I take it that you can also find and flash a kernel compatible with your ROM.
To be honest, from your description, I don't think any of the above will help you (but you can try, if you want). I believe that your power button is stuck to "pressed" state. If you could spray it with some contacts cleaner while repeatedly pressing and releasing it, you might get it to work again.

won't get into fastboot
hay i have GB and i want to install wkparks bootloader , but the problem i couldn't get into fastboot i had fallowed the guide but at the end it dosn't show silver LG but the touch buttons is on and when trying to flash the bootloader just show waiting for device after selecting "flash bootloaders" , i'm on win7 64bit and using v1.3 .
photos in attachments shows what i get when trying to install the bootloader
so any help i'll by pleasured

Hi guys
Does anyone know what is the best course of action to revive an lg p920 running stock ICS and died after twrp 2.3.3.0 was flashed via twrp manager from the market.
The screen went black and phone completely dead now.
I just ordered a factory cable on eBay and wondering whether to flash kdz or is there another fix that I can flash to revive it?
Cheers..

Solved
Even with factory cable, windows 10 PC was my problem.
I flashed kdz on a different PC running windows 7 and all is working fine.
