- Error of insufficient storage when installing an application or
- Internal memory will be displayed as 0 or
- You simply can't install applications
The fix is easy.
As you know, if you reboot to recovery on stock ROM you'll do a factory reset. So, we'll use this to format again your /data partition to EXT3 and everything will be fine.
But how will you reboot to recovery without being able to install AnReboot or Terminal? Well, you use this:
Download this, run goto_recovery.bat if you're on windows or goto_recovery.sh if you're on linux and voilá, problem fixed. You'll need to connect your Black to your PC and enable "USB Debugging" on Settings > Applications > Development.
Go to Hidden Menu (write on dialer: 3845#*970#) and do a factory reset.
Go to Settings > Privacy and do a factory reset.
