hi ! i installed Gueste2X v3.0 Hybrid Revolution which has EX4 .. i wanted to go back to the stock via a nandroid backup .. but sadly i downloaded and flashed a backtoEx3 for the G2x ! now i cant boot into recovery and i have a boot loop ! any ideas ?
I guess that you already tried pulling your battery. Can you get your phone to software upgrade screen? Pull battery and insert usb cable. Boot phone with volume key pressed. If this works you can for example nvflash your device.

With phone off hold volume down and pwer button down until a different lg logo appears then you will get to the recovery

Hope it helps....
Maybe you can try the nvflash method to save your phone
make sure the drivers and bin rom are ready in your computer
take off the battery
press the volume up and power key to connect to the computer

I just restored my phone to stock rom using rom manager.. After rebooting the phone just keeps on blinking like every two seconds with the LG symbol. Is there any solution to fix this ? Please help..
can you get to "recovery mode" ?
pull out battery, does it still do it when turned on again?
i had this when i used (Rom Manager) to restart my fone into recovery once, it doesnt correctly follow instruction some times.. however manual CWM usually works.

which ROM you were in before?EXT3 or EXT4?
if you gone back to Stock, u used a smartflash method?did u do the three wipes?switch off the phone, then hold vol down + power key button until you get the second greyish LG logo and then choose wipe data/cache and dalvik (to make a fresh an clean flashing)and reflash the stock ROM...it should be fine then.
hope it helps
from reading the log (as it quickly fly's up the screen) you will see it does this automatically
try nvflash and try to update your recovery.. if your using cwm recovery use 5.0.2
thanks for the help guyz.. its fixed.

Hey guys so I did some stupid things and ended up where I am currently...its a long story so please bear with me...
Due to some water getting into my phone sometime ago my home button broke(hence cant go into recovery, without adb)...So I started using Button Savior and navigation bar in CWM ROM's...then I switched recently to Ultimate Rom...I was running Ultimate ROM (LSZ_JB_4.1.2_v5.2) and it was all well ...until I pulled out the battery while the phone was on and it got stuck in a boot loop...
This bootloop went to the samsung animation for 2 boots(I was not at home then since I could have gone into recovery with adb right then and there)...but when I got home the boot just got stuck at the splash sreen(black and white "Samsung Galaxy Note) and adb couldnt detect a device(adb reboot recovery couldnt be run)
Now as I couldnt go into recovery by any other method,so I went into download mode and flashed GB+Prerooted+CWM stock(Dr. Ketan's thread) and it still wont go into the boot animation section so that adb could be used to boot into recovery...
Basically I want something like this right now:
A ROM that would do an auto wipe after flashing using Odin.
like: http://forum.xda-developers.com/showthread.php?p=26484341
As I'm sure a full wipe is all that is needed to solve this issue.
But I can't access recovery because my home button is broke
Could someone kindly point me to a ROM that would do this?

look for roms that has Wipe written besides it..
these roms are not rooted so... you will not have cwm

SOLUTION:
Reflash .kdz via Software Upgrade Mode (hold Power button and Volume - )
Dude, reflashing your phone should work. As long as SW mode is still accessible, your phone isn't dead yet. Follow the instructions on this post http://forum.xda-developers.com/showthread.php?p=35971349 Be freaking sure all necessary drivers are properly installed.
Or you can put your phone in recovery mode (power + vol +) and reinstall the stock rom using recovery LG tools providing your Internet connection is fast and stable

hey dude, i have flashed 7 times exactly since this morning only. and i have gotten that error 3 times of those 7. so it should not be a problem
Thanks!
After a few attempts, was able to go to the s/w upgrade mode.. (power + vol(-) )
Reflashed .kdz and it's all good.. (had to root again)
Actually, i was freaked out more coz it's my new phone and i didn't find others with the problem..
I hope that this thread would help if anyone faces a similar problem in the future..
Thanks for the prompt response, guys!

You needed to unlock bootloader first, either "adb reboot oem-unlock" or download terminal emulator, root the phone and type:

flashing stock is not at all dangerous. it will not brick your device or something else.

you installed cwm without unlocking bootloader. re-flash 20a/20b (jellybean 4.1.2) kdz, then unlock your bootloader, then install any custom recovery you want/need

Bootloader unlocking is only available if you're on JB. If your boot image is faulty you need to revert back to official JB.

So if I understood you right, you tried to install CWM without unlocking your boot loader? So now you got a boot image error? I'd suggest to try LG Mobile Support Tool and flash V20A/V20B and then unlock Boot loader. Even if you're on "official JB" as of now, installing CWM without unlocked bootloader screwed your boot image and there's no way to do anything without flashing back a kdz.

Hey,
I have tried to do the Update to the Firmware by LG Mobile Support Tool but there is a Error every try. I have tried it about ten times but the Update fails every time. What can I do now? :/
There is no Error Code or something.
Can help a factory reset there?
Or should i falsh the Original Recovery with the All-in-One toolkit?

Unplug and Power on your phone together by vol down + power button. AFAIK,only if you plug in and press vol down, you will go into software mode.

there's a solution that worked for me when I had my LG p990 and it happens the same issue that you are experiencing
1. Connect phone by USB
2. Enter 3845#*880# in dialer
3. Select Port Settings -> Select CP USB
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your orginal IMEI number
8. Reset
only works on stock based rom, maybe you should try, you need a pc with hyperterimal
