Hello, I have a moto droid global 2. System Version: 2.3.330.A956 Android Version: 2.2 Kernel Version: 18.104.22.168 This has been happening for awhile, but I've been too lazy to ask why and how to fix it. I have plenty of internal storage and SD card space. The reason why I'm running 2.2 and an outdated system and kernel version is because for some reason I can't update it. However, I'll ask that question at a later time, unless it's because I need to update it. Oh I almost forgot to tell you guys the problem. I can download all application from marketplace and anywhere, but I can't install all of the applications I download. It says ""Couldn't install on usb storage or SD card" when I try to install some application. One example is Frontline Commando. So please help me. I have rooted my phone using z4root if that matters. I don't have a custom rom. I had clockwork mod installed, however I did. My phone would turn into clockwork recoverymod every time i turned it on and off but i deleted clockwork with root explorer.
