Hey guys, so this is a problem that is driving me crazy!

Recently flashed new rom - Harmonia 2. I started using Titanium Backup to restore apps, but eventually got to a point where I would get the message "____app not installed".

I made sure to move apps to the SD card, same problem. When I go to Google Play market and download apps, I get "error, insufficient space on device" message. I even tried downloading app files and copying them to SD card, in which case I get "package file invalid."

I have plenty of space on internal and external. I've tried doing a factory reset/wipe, cleared cache and dalvik.

Any suggestions?
Update: Followed these instructions I found on this thread:

# cd /cache
# mv download download.old
# mkdir -p /sdcard/cache/download
# ln -s /sdcard/cache/download download

Now market will download app, but when it goes to install, I still get "package file invalid". Tried wiping data.
Open your file manager navigate to etc/init.d/ and if you see the file 01mvdalvik move it to /mnt/sdcard/ then clear the cache and data for Play and reboot into recovery. Wipe your dalvik and cache in recovery and then reboot.

You will have much less internal memory after this. The script you moved (if it is there) tells the OS to move the dalvik to the system partition instead of the user partition. This causes problems with Play sometimes.
