Hello! Decided to flash your LG GT540, which is Android 2.1 to version 2.3 (with the purchase of the phone was version 1.6).
Found the article
, it briefly describes the installation process. The problem faced in the beginning. Can't boot into fastboot. When you download through recovery, turn on the phone in safe mode and it is not clear what to do.
The gugleniya did not give a normal installation. Perhaps someone from kirovchan to share experiences and advice or link to a detailed description of installing Android 2.3 on LG GT 540.
Thank you for your attention.
