The Hard reset did not work for me.
I did the following steps:
I resetted my phone, using *#7370#
I Try To install the qt_installer.sis From the Qt Nokia SDK
and then breaks the installer:
SWI error 0 c:\sys\bin\pipelib.ldd
I unpacked the qt_installer.sis and extracted the files to the memory card. All of them Install correctly, except the qt.sis and the pips.sis.
When I start the qt.sis i soon get to a point which tells me:
If i continue, my applications don't work on the phone.
Component 'PIPS Installer' missing. Continue anyway?
When I try to install the pips.sis it tells me:
looks like a chicken is searching for his unlayed eggs here.
Unable to install. Component is built-in.
Any more Advice?
