hi,

This happens when i try to apply firmware using ODIN.
Only the first block completes in ODIN. After that it shows Reset in ODIN and following message in phone

Android system recovery <3e>

Enter: OK Key. Select : Vol UP /Vol Down
reboot system now
apply update from sdcard
wipe data/factory reset
wipe cache partition

i can't wipe data/factory reset. the same error pops up. also wipe cache partition shows error.

on rebooting phone works and shows firmware as XXKPN GINGERBREAD. The same happens after rooting, but phone does work, only problem being not able to back up and accessing cache.PLease advice what should be done. Once again phone works normally, but i do want to make a nandroid backup
