Root Market install hang possible solution.

[ArmlessRifleman]

If anyone has been having problems installing apps from the marketplace (app finishes downloading but hangs during install) try this. It worked for me.

1. Log into your Google Checkout account via PC.
2. Delete all payment methods and shipping addresses.
3. Clear your market cache on the phone.
4. Install a new ROM
5. Open the market and re-download all of your apps DO NOT USE TITANIUM

I had tried multiple different methods in order to resolve this issue and this is the only thing that has fixed it for me. Others will tell you to make a new Gmail account for your phone but then you loose all purchased apps.

If you do not follow these instructions and still decide to use Titanium Backup to restore the problem will come back even if you choose to restore only the applications.

Adrynalyne already found an adb solution for this. Send him a message to ask which command. It's something like adb installlocation=2

Just asked him now. I remember using that same command to try and resolve the issue previously but it did not stick after a reboot on my device.
