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
I tried Philz recovery to install a new rom but after choosing "clean to install new rom", I rebooted the phone by mistake :crying::crying::crying::crying::crying: And now I can't turn it on with the power button, when I try to force reset by holding both power button and volume up, it just buzz once and Sony screen show up then down just after a few seconds. After that nothing happens. I tried to connect it to PC and I just got the notification that USB cannot recognised... I can't enter fastboot or flashboot mode
How can I do now?!?!? I'm so feaking out now :crying::crying:
Have you tried flashtool?
If you use it to flash a stock rom, your phone may work again.

Try to get to recovery again?
Hey!
I successfully flashed the debload zip from here, then i tried to restore some apps i need and went for a reboot as required.
Now im stuck into a bootloop and cant get access to the recovery.
I tried to press vol up or vol down several times after the led started glow green (in all tutorials it says it has to be violet?!)
How can i fix this now?
When led turns green and phone vibrate then press and hold vol up or down till recovery starts. If not i think u have to flash tft and do the whole root, recovery process
just recently, I just downgrade my phone from CM11 (KitKat) to JellyBean. there's some error while flashing the rom. Im quiet sure about it. whats more important is that now my phone just cannot boot properly, when I start the phone its vibrate like always with green led and right after the SONY logo, my phone just switch off.. I cannot access anything even recovery mode. and there is one another problem, when I plug in usb, green led light shows up, later for about a minute my phone automatically boot up with RED led then just after SONY logo it switch off again, and then goes green led on back and red led comes again off right after every SONY logo, just like ON and OFF again & again..
Sorry I dont know how to describes it, and sorry for my bad english if you guys find it hard to understand. PLEASE help in this case!! Thank you in advance!
You must enter fastboot mode. Erase the boot section and flash a new boot image (.img) or a kernel .elf file.
Use the commands:
> fastboot erase boot
> fastboot flash boot boot.img or fastboot flash boot boot.elf
> fastboot reboot
After that, if the boot.img contains a recovery system, it would be installed and now you can enter recovery again and reflash your rom.
I think that any boot.img inside a CM Rom zip file have a recovery system.
Are you familiar with fastboot mode? How to enter, usage, drivers?
Please give me the instruction on using fastboot. Im not very familiar with fastboot.
How can I find the img, where to download? and how to use it.
Thanks by the way for tips, I think I've been using the wrong rom, I dont know which is the right rom to downgrade to stock.
If you want to downgrade to stock i'd recommend you to use the Flash tool for Xperia.
You can download it here => http://developer.sonymobile.com/downloads/tool/flash-tool-for-xperia-devices/
Follow these instructions => http://developer.sonymobile.com/services/flash-tool/use-the-flash-tool-for-xperia-devices/
You need to do the step 4 right for it to work.
I guess it will solve your problem.
If you have any other question, just ask.
As I mention before on the previous post, the problem is every time I plug-in usb the device keep on connected and then disconnected. on and off, and booting itself with red led till the SONY logo come off its shutdown and green light appeared again. Its like not properly connecting the device.
Is that okay to go on flash mode? may it not been error before operating this?

Keep the usb connected.
When it reboots, before the sony logo appears, keep the volume down key pressed. When the light turns green, the phone entered the flash mode and you can release the volume down key. I dont know if it will reboot again. If the phone enters flash mode (green light) and reboots after that, maybe is a driver issue. In fastboot mode (volume key up + blue light) sometimes this heappens. I dont know about flash mode.
