Hey you guys! maybe can help you...
first of all you must backup your 3310 with address that starts in its PPM level and EEMPROM level..
be sure to upload full flash ac cording to the phones software version or else it will really 100% f**k your phone..
after uploading full flash re-upload saved fls files with PPM and EEPROM..
thats it i hope it will make your good as new as it was the same the day you bought it from a cellphone dealer...
CHEERS!
