If your P800 has the R1D version firmware on it, the normal UIQ installer may not work. The installer in this folder will work better.

We have reports this installer too will hang at the end of the installation. If this happens, wait for a while and then restart your phone. Everything should now be installed properly.

Note: You really should update your P800 if it has R1D on it still. You'll benefit from many fixes and new features in later firmware versions.
