    Hello Friend,

    Yesterday I have rooted Galaxy SL I9003 and want to updated it with Jellybean.

    I have followed proper steps and rooted the device (confirmed it by using rootchecker app.)

    While updating it with Jellybean device shows folling errors:

    1) I had place jellbean zip into internal SD card and it is detecting.
    2) Into recovery mode device doesn’t display the “advanced” to clear the Dalvik cache.
    3) Still I had selected “Wipe data/factory reset” & “Wipe Cache partition”
    4) Then selected zip file to recover mode and it display this error, “there is no space into sd card, installation is aborted”
