I also flashed back to a stock rom yesterday (was running overcome)
XXJK5 as I couldn't flash JJ3, it appears to be impossible to flash a firmware with a hiddenfs.rfs partition?
Flashed xxjk5 with repartition on and it was ok after adding also the multi-csc, otherwhise it boots into recovery with an error about "unable to mount..." and "datadb not found...."
The only thing, there must be some problem with this multi-csc file,
the list of salescodes doesn't contain XEU (*#272*imei#), while this xxj5 rom I downloaded was XEU.
KIES tells me by the way "this version cannot be updated" and I find only 3 apps in samsung apps :(
