Applications wont install, unknown reason - Page 4

This isn't isolated to custom roms. I am using stock 3..(not the latest) rooted using unrevoked. I have this error all the time when updating apps from the market. The only solution is to unmount then update. It's annoying but the only solution I have found so far.

I had this issue too except I didn't get an error message. The app would download but never install. I tried to unmount which worked, thank you! However, I also noticed that everything on my home screens was duplicated. By this I mean if I deleted a widget, shortcut or whatever, it would still be there. I would have to delete it 2 or 3 times before it was gone. Moving an item would result in 2...the original and the one I moved. My only guess is the dups were created when I restored my back-ups. After I got rid of all the dups and a reboot, my install problem went away.

If you do not want to flash a Rom clean, I would at least go into revocery and wipe everything. Wipe Data, Cache, Davlik VM. Let it all get recreated.

If it were me, I would would install something like Sprint Lover's All-In-One Rom since it is very stable and clean. You have to get to high ground with these issues.
