galaxy star pro s7260 hangs on boot and vibrates and dont turn on

galaxy star pro s7260 hangs on boot and vibrates and dont turn on.Recently i flashed with a new updated firmware.Then everything was ok.But i did a fault.I then flashed the phone with wrong pit file.Now odin also can flash the phone with the stock firmware.After flashing with the stock firmware the phone hangs on boot and vibrates.i think it might be the result of flashing with wrong pit file. if gone to recovery mode it says failed to mount data.when i format data and cache then it mounts data correctly.But the problem of boot loop and vibration still stays.then recovery says 'E:missing bitmao icon att fota error tmo fota error'.I will be very glad if anyone help me.
seems like a common error, my Galaxy Star (GT-S5230) also has this, you should flash a custom recovery and try to wipe it.
