There was no boot images of ... recovery did not appear any image so I decided to follow these initial steps had already worked with another person:

1) Download the French v20A (hxxp: / / csmg.lgmobile.com: 9002/swdata/WEBSW/GT540/ANEUBK/V20a_00/V20A_00.kdz) and the out.kdz (hxxp: / / narod.ru/disk/25473801000 / out.kdz.html)

2) Take Out Your battery, SIM and SD card

3) USB plug into your PC (but not phone yet)

4) Hold Vol - button and plug USB into phone - phone goes into Download Mode

5) KDZ run Updater, put it into mode CS_Emergency

6) select V20A French rom and flash it

7) When It's finished pull out again and hold Vol USB - USB and reinsert phone to put back in Download Mode

8) in KDZ Updater (still in CS_Emergency mode) and flash it out.kdz select

Once you get make this whole process, I tried but nothing happened except a vibrating beeper, then tried flashing a rom for fastboot ... but seems not to have fastboot because I can not ....

Now I have the phone is unusable because the display mode ... I tried to download some roms flashing emergency cs in emergency but without success ... I NEED HELP! willing to pay to those who really help me ...
