I FOUND THE CURE !!! TRUST ME THIS WORKS!

If you ever get the "App. Closed Main" error when you bootup, this will fix it.
Using your file explorer go to e:\system\programs
You will see some various files in there - but we are just gonna concentrate on the .exe files.
One or (some) of them are giving the error when you bootup.
Click them one by one and if it gives you an error, just delete it.
You can do this if you get any other error during bootup aswell.
This method surely gets rid of the boot up errors.

Sticky anyone?


Sometimes this is a problem, when you have deleted an application and its scattered remnants have been left in the memory either of your phone or on MMC card. When the phone boots up, of course it searches for the ‘badly’ removed application(s). Another solution for avoiding such message as ‘App. Closed Main’ at all, is to use UnMakeSis software when you are removing application(s) from your phone. I usually open *.sis file on my PC with UnMakeSis to see which files to which folders are copied during the install process. When I remove application(s) from my phone, I also open *.sis file of a removed application using UnMakeSis and see which files might have been left during the removal process in the memory. Then I remove those remnants manually. Hope this also might help
