Got several issues on my Dinc when I booted this morning. Here are all the symptoms I see:
1)None of my downloaded applications are recognized as installed-I only see the factory-installed apps in the app launcher 2)Settings->Accounts&Sync gets FC (com.htc.settings.accountsync) 3)Settings->Applications: While I do see all my downloaded apps in the list, the icons don't load for them, and when I click one, I get an FC on com.android.settings 4)Phone storage/SD Storage numbers look good 5)When I boot, the notification bar shows "Preparing phone storage", followed by "Preparing SD Storage" as it normally does, but the Sync icon only flashes for a second.
I'm running stock 2.1, no root...just a normal every day phone user. Was reading articles with the Time Magazine app prior to shutting down for the night. Had plenty of battery left, so I didn't even plug it in.
It seems as maybe you have downloaded a corrupt application or have a system settings error. The only fix currently is to perform a hard reset and wipe out all the settings. The steps for the hard reset are below:
Performing a factory reset via settings
The most convenient way to do a factory reset is via the phone settings.
Press HOME > MENU, then tap Settings.
Scroll down the screen, and then tap Privacy > Factory data reset.
On the Factory data reset screen, tap Reset phone, and then tap Erase everything.
Performing a factory reset using phone buttons
If you cannot turn on your phone or access the phone settings, you can still perform a
Factory reset by using the buttons on the phone.
With the phone turned off, press and hold the VOLUME DOWN button, and then briefly
Press the POWER button.
Wait for the screen with the 3 Android images to appear, and then release the VOLUME
Press VOLUME DOWN to select CLEAR STORAGE, and then press POWER.
When asked to confirm, press VOLUME UP.
Once you have done this it should resolve your problems. Hope this helps
