Overcoming the Main App Closed Error Without Format

The steps are as follows:
* Run the file manager to track files in the phone (such as applications, SeleQ, Fexplore, YaExplore or other).* Navigate to the folder C: \ system \ bootdata, then select 'Firstbootdata'* Select the option, delete files.* Next turn off phone and remove the MMC from the phone.* Once the MMC is released, restart the phone without MMC (will appear hour format and enter the date and hour).* Turn off the phone, then reinstall the MMC and restart the phone.
* The phone has normal.

Note : 
To avoid a change on the phone menu, you can perform the following steps :

    * Backup files aplications.dat
    * Use the file manager to explore the data, C: \ system \ data
    * Select Applications.dat, press option, copy
    * Then "paste" the file is a safe place, for example: E
    * So if you want the phone display menu again like before making repairs. Just do a copy backup file aplications.dat earlier into a folder (C: \ system \ Bootdata). Press yes when the display appears to overwrite the file.
