How can I fix Xperia x10i application crashes under CyanogenMOD 6? I have a lot of issues with my Xperia x10i:


I get a lot of forced close of apps
I don't have zoom in my camera nor flash light
I don't have Mediascape nor Timescape and maybe other apps I don't know about
From time to time it reboots from its own
My music app dosnt work
My camera doesnt work in apps (like Goggles or Barcode Scanner), it just gives me colorful stripes and no picture


As far as I know Sony has only released Android 2.1 for this phone and doesn't plan to do 2.2, But I noticed (in the info tab section) that my phone is 2.2.1! It seems that it was rooted and had Cyanogenmod 6 installed.

Please help me fix my issues.

i also have several question to understand a bit more :
  is my phone rooted? and what does it mean exactly? 
  and if i do this would i still have Cyanogenmod? can i get back after that (i like its features)?
  and what does rom and mod mean?

Thank you
I would recommend going back to the Sony official firmware.

This thread has step-by-step instructions for reverting Xperia X10 handsets to stock ROM.  You might want to search the thread to confirm that the process is the same for your X10i model before starting.

Keep in mind that flashing to the stock firmware will erase all of your settings and installed apps, so back up the important bits.
