All went well. But I did not get the option to choose between storage and sync. Also, I lost (or at least some of) my downloads from the Store. I'm still cheking...
Is that because the image I downloaded was not a perfect match with my model number?...

EDIT: I did have to re-install from the Store all the apps I downloaded and purchased before flashing. They were all in my "download history". It was a pain to re-download and install all of them (Motor Academy HD is >300MB).

Also, dev mode is gone. Filebox (re-downloaded) doesn't allow me to use Terminal. So I guess after I'm finished downloading from the store I will have to re-activate dev mode. I downloaded and installed the deb package of syncevolution. I guess I will have to re-install that too...
