The first thing I did on my new BB 9900 is by loading to the newest firmware but before that, I like to Shrink it by removing unwanted COD files to save some memory space.
However, I met with the following issue after I install the OS
I can't find a solution by searching on this forum and Google.com so I decided to jumb in and find out what causes the problem and share my findings.
Basically when you Shrink your OS using the BBH Tools, DO NOT remove Maps. Doing so will cause the above problem when loading your OS. You can remove it LATER with Desktop Manager if you really want to or simply delete the application from your device.
Again, DO NOT remove Maps
