GD87 problem
 

Phone was locked, version a53 vodafone branded.
Downgrade to a22 read code phone was just blinking.
Upgrade to a53 enter code phone unlocked.
But now no ringtone in phone.
CB2000 have empty field at media pack info and checksum.
I flash many version a39,a51,a53,a55,a58 but didn't solve problem.
Also main flashing go slow until ~10M then quickly go to finish to 16M and looking inside files noticed there is big empty area.
How can I solve this problem?
Maybe I need full flash not just upgrade,but can't find any one.

And the problem was hardware.
My mistake because beep on key press was so loud and this fool me to think earpiece is speaker too.
