OK I really screwed things up here. I was only trying to install more apps and I noticed that the internal memory card on the N810 was filled up. So I tried to move the huge map files over to the removable memory card (with a lot of free space) I did so, and then it only moved a portion of the map files over so it was like half in the external memory card, and half in the internal. I used file manager to simply move the files. I try map out and it still works but its annoying cause it always says "we found files in two places etc etc) and then anyway I just went ahead and uninstalled map and now I try to install it again and it hangs up. Control panel, it hangs up, application manager - it hangs up. Backup / restore it hangs up...

Is my only option to flash the device? I dont even know how to do that

I am down to leaving the battery off for 15 mins now. Something is hanging it up even after several restarts. (I have the load indicator app so I can see something is eating it up - )

I am a bit pressed for time now but will be happy to answer any questions.
