I'm trying to flash original LG .kdz rom but I cannot boot in SW Upgrade mode
what I do:
1. remove the battery
2. hold the vol down button
3. plug the USB cable.
what happens:
the LG logo is displayed and after several seconds the screen flashes (like something will start) and then the phone goes off.
I have clockwork recovery installed and custom rom .. I what to try the stock V30 ICS
ANY idea why is this happening ? and how can boot in SW Upgrade mode ??
don't remove battery and try again
be sure to install correct drivers and you should see S/W Upgrade not the LG Logo..if its still not working try it holding harder.

Hi,
I just flashed Darky's rom 10.2 and now when I boot my phone I can see the GALAXY logo and the "powered by DarkCore.." but it stays like this for several seconds and then just become black and then the logo reappear all over...
the phone it self wont boot.
I cant enter recovery or download mode either.. if I keep pressing (the volume buttons) a battery (?!) icon is shown, if i release - The logo come back.
WHAT CAN I DO?
Don`t panic. This sounds like a pretty simple boot loop.
To get into download mode, plug your phone into the wall charger and use the three button combo. Flash back to stock and start all over.
remove the battery for few second. put it back and use three button combination to enter into download mode and try to flash RE. Make sure repartition is ticked. Check my signature for the guide...
But...
I had my lag fix turn on..
now i cant get to the settingh (cause the phone wont boot...)
It wont damage my phone to flash?
And by flash you mean with Odin and all the the basic GB?
Shouldnt i get to recovery mode and just flash the Darky 10.2 all over (with wipe and all..)
???
Hi,
I recently flashed official V30a (Europe rom) for O2X and wanted to flash back to V20c (Starhub). However, I didnt realise that the partition and bootloader were different between ICS and Gingerbread. So now basically my device is in a bootloop and it's bricked. Tried enter Nvidia Mobile Boot Recovery (VOL UP + VOL DOWN) many many times but nothing happens on my PC's device manager screen; no device detected. It can only enter SW upgrade mode (VOL DOWN) but it's useless and i cannot flash any roms with ICS bootloader and I need to flash NVFLASH RECOVERY first.
I'm desperate as Nvidia Mobile Boot Recovery is the foolproof method to unbrick and it cannot work.
Any ideas??
Try this one [TOOL] Full Brick Repair (Clean & Easy)
To nvflash mode remove battery push vol up/down then plug in usb.
use smartflash to flash v20c, leave battery in phone and it will work
SOLVED
today i try to changed my rom from cm10 to ICS
first i nvflash stefan v28g with CWM and new bootloader, it successfully flash stefan rom and boot normally
second i transfer django ROM to my external sd card with change vold.fstab and flash it through CWM and successfully flash after that i reboot my phone and it is stuck on a lg logo with a unlock padlock icon with lg word with it
third now i'm trying very hard to repair my phone but it doesn't work i try to enter to nvflash mode but it doesn't work even i press it very hard and try to press it with the battery attached but it show me the same image with a padlock and lg word
can't enter to smartflash or software upgrade also
but my phone is still booting but stuck on lg logo with a padlock and lg word to it
how can i repair it i try already tried all but it is required nvflash mode
SOLUTION
ok i managed to solved it by my self
for users who can't enter nvflash, smartflash, CWM and stuck on lg logo and after you flash volume + and - here's what you need to do:
1. press volume + and volume - observe closely the screen you can see a screen that turn on and off quickly (important! don't loose your grip and keep holding the volume + and volume -)
2. press the power button and hold it for 5 seconds and you can hear a sound from your computer or a notification that their is a device that is connected
3. then nvflash
delete

Hey guys,
I've been following the instructions on felipemadox's thread on how to flash .kdz files to return to a stock firmware. It requires me to enter the S/W upgrade mode.
I've tried holding power+vol down (whilst plugged and whilst plugging in) with the battery. It comes up with the LG logo, the touch keys light up for a second and then the screen goes black. If i continue to hold the buttons down, it just does a loop of the above.
Any ideas on how to get into S/W Upgrade?
Thanks in advance!

I don't remember well but I think it is just the volume down button with the USB plugged in....you have software update screen
By the way are you on the leaked ICS boot loader...use all in one tool kit in Dev section to flash the unlocked boot loader and then Terry smart flash again
Hope it helps
O2X with Magical ICS ROM and supersonic kernels from my buddies
hold volume down only while plugged-in on your usb cable
Thanks guys, maybe it is a problem with the phone, but after about seven tries it somehow booted into the update mode.

i already have seen some tutorials where butt my problem is connect the phone with pc, when i press the power and volume down the lg gives-me the error i said and the phone turn off, so i don't know how to connect the phone with the computer ...
just downloand open europe v20a flash it with kdz flasher remove battery put usb cable while holding the volume down after you mast have install lg drivers run kdz flasher slect the kdz and press flash put the battery back and leave the phone the program will freeze is normal dont afraid and after when the phone open unlock your booltader first root it and after downloand rom manager and flash recovery through this app but is not touch recovery is normal recovery
Can't this be solveed by simply reflshing recovery?
The phone gets into s/w mode so just type from terminal
-> fastboot flash recovery "recovery.img"(change with name of img file in this case)
Obviously try with a recovery different from the one you already tried with
