Thanks a lot for your reply. I decided to try the V20B KDZ version with the LG Tool (KDZ_FW_UPD), but the process fail.
Then i used another KDZ (Rumanian), the
V20G and this work like a charm on my p500h!!! :]
Im very happy, because the new keyboard is awesome, and the LCD cpu bug was deleted on this release (tested with "Usage Timelines Free").
PD: For root the 2.3.3 version i used the SuperOneClick tool, please
follow the next guide for do it in your GB P500 (Titanium Backup and BusyBox work fine on my rooted phone. I suggest you install the SuperUser app from the Market after the root process).
