GT540 doesn't boot

Helo,
I've got a big proplem, my GT540 doesn't boot anymore it always freezes when the LG sign appears. I have this proplem since I'd tried to change the statusbar font into whiteby changing the services.jar. Hardreset and KDZ Updater aren't working. And I also tried to change the new services.jar to the old with adb but I don't get root permissions.
My phone runs with 2.1 Eclair.
Thanks for your help,
Lucas

Wait, arent the status bar white by defoult ?

No i don't mean the bar I mean the clock, but do you have any ideas to solve my proplem?

Do The Hard Reset With Press The
Vol Up + Search Key (on the right side of the phome) + home button

When I Trie to do the hardreset it Happens nothing! Is there no other possibillity to reset?

You could try fresh install with KDZ updater, that worked for me when I broked the radio and my network didn't worked. If you have troubles geting in to download mode you could try removing the battery and press volume up + camera + power button Just be carefull! Good luck

I tried this too, but it crashed always after I choose the kdz file
Here is the log file of KDZ Updater, rename it to Fail.log

OK, you could try this :
If you have problems with KDZ_FW_UPD - Download and install from Microsoft two files "MSXML 4.0 SP3 Parser" and "VisualC Redist"
1 LG_Android_Driver Ver 1.0 must be installed
2 In the Device Manager disable LGE Android USB Modem
3 Run Windows Enabler (on Windows 7 as administrator) and left click on the icon in System tray ( it should be ON )
4 Run "KDZ_FW_UPD.exe" (on Windows 7 as administrator)
5 In the "Type" select "3GQCT", then choose the firmware file
6 Expand the window of the KZD flasher ( more options will emerge )
7 In the "PhoneMode" section choose "CS_EMERGENCY"
DIAG - standard flashing mode of ON state
EMERGENCY - in extreme cases!
CS_EMERGENCY - the same thing, CS - crash systems
8 Click "Start update" will process the firmware
You could also disable your anti virus and use only the back USB ports of your PC. Good luck !

Oh THANKS! I love you guy, I thought I killed my brand new mobile!

It worked for me when i wiped my phone.

Cant get it to start reloading the firmware
Can you please tell me from where to get the file KDZ_FW_UPD.exe in english I have it in Russian.
I have tried in DIAG mode but failed...
Please help..

The upgrade does not start...
Very GOOD now it did it like this.
Start your phone in recovery. Volume down+camera+power, see if the pc sees the device. Start the update tool max it and select emergency and flash again.
This fixed...
Now I need to add spanish to it. Do you know how??

Pleaz help us =(
My PC don't see my phone, my phone stay on 'lg' boot, and can't boot on emergency or hard reset... =/
EDIT: i did it!
You only need to desactivate the LG Android USB Modem (i didn't saw 'Modem' on Device Manager, so i could not desactivate it).
If like me you don't see Modem, you will see it during the period of time during which the device is recognized mod download, ie for about 5 seconds after you plugged in...
I hope it will help someone
PS: Sorry for my english..

Look under modem and you see your phone
At property under tab look your com number remember it
Take teraterm create a connection with your phone you can connect it normally
When you are connected write
AT
( if you see nothing go to setting general and activate ''echo typed only'' )
If your getting OK
AT%FRST%
and the phone does a factory reset
( i'm french so i'm sorry for my english )

[Q] G2 goes black after tried to update using LG Flash tool

I have a serious problem with my LG G2 D802 which I could not solve: I used the new LG Flash Tool 2014 , everything was going just fine till I received an error recovery failed, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (49% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope anyone can help me.
Itried pressing power and volume button down together and aa lot more don't know how to slove.

I just want to ask, actually i am using LG G2 D802, which is international version, so hope these files are for my phone. How to stop the pop up "unable to mount..." error messages , in ubuntu.

You have the answer in the OP :

Excellent tutorial! Thank you! Phone is working again
You can stop the "unable to mount..." error messages from popping up by disabling
the automount feature of Ubuntu.
"To enable or disable automount open a terminal and type dconf-editor followed by the [Enter] key.
Browse to org.gnome.desktop.media-handling."

[Q] Settings and keyboard don't work

Yesterday my brother rooted his G2 and deleted some apps, including Calendar. Now most of the settings and keyboard don't work. He gave the phone to me and I can't even connect it to the computer in other modes than "charge only". WiFi doesn't work too. I tried finding out answers by myself but couldn't find anything I can understand.
Edit 1 - Hard reset didn't work. The phone was bought from Finland so I think it's the International version.

Did you perform any kind of back up before deleting the phones system apps?
If you didn't your best bet would be too simply Return to Stock Firmware.
Next time don't delete important system applications!

I did everything in that guide, but the problem is that my pc doesn't recognize the G2 so I can't flash it.
When I connect the G2 into the computer the G2 shows error message "Unfortunately Settings has stopped" (translated) and doesn't give any other options than charge only mode.
Edit 1 - The phone shows up as "HID-compliant vendor-defined device" and "USB Input Device" under "Human Interface Devices" in device manager.

That guide requires you install ADB drivers (so you phone gets detected by the PC) and then to enter download mode.
You shouldn't be getting a "Settings has stopped" error in Download Mode.
Install ADB Drivers.
How to Enter Download Mode on LG G2
Your phone must be turned off before starting the steps from this guide.
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.

I installed the ADB drivers but the phone can't get into download mode.

All problems fixed!
If anyone has the same issues, here's what I did to fix them:
1. Read this thread , stopped after step 9. The device showed up in Device Manager as Qualcomm 9006 or something like that.
2. Did this.
3. Entered download mode
4. Used LG Mobile Support (downloadable from LG website) to "fix update error".
5. Downloaded Google keyboard apk and moved it to the phone using MTP.
6. Installed the app.

LG G2 Hard Bricked?

Hello friends.
Just today I tried to flash CM13 on my D802. I did. After that, I pressed reboot system as usual.
This is the weird thing: after pressing that, the phone showed the LG logo for a second then the screen went full black.
Now I can't boot the device. I have download mode available... No download mode though.
When I plug the device to my PC I get a ton of Windows Explorer prompts saying "You need to format the »something« in orded to use it". Like 10 of these.
Please help? I still have download mode available to me.
I already tried LG Flash Tools to return to stock but when it gets stuck on 60%. Then i get the message "the phone is disconnected from PC or USB". When I try the R&D Test Tool i get the message "Port or Serial not found"... Please help...
