I would like to let you know, I finnaly got rSAP working again.
The problem is, I'm not sure how.
In the LG PC Suite I clicked on the menu point to repair a broken update or something like this. This installed a complete Stock firmware. And the rSAP was working again.
I would like to show my gratitude. What would you like? I could buy your app, or do you have some sort of donation, or paypal?
