Recovery mode entering problem on ace

[Android Question]

Hello,

I have a Problem entering recovery mode , after my phone got stuck on an application ( as it always does ) i rebooted it , but it stuck on the Samsung lego and it's staying there , so i tried to fix it by using odin , after downloading the files to my pc , i entered recovery mode , but the pc didn't connect to the device.
so i had to unplug my device from the pc a few times maybe 5 times and i turned it off 2 or 3 times ( it was on recovery mode but not connected to odin yet ) , so , finally when it connected to another pc , i tried to enter the recovery mode again but it's not entering it or the download mode .

My questions are :
why it stopped entering recovery mode and download mode ?

and How to fix it ?

i tried to charge it for a while but it still same problem ,

Please Help , thank you .

my device is :

Samsung galaxy ace GT-5830i

Android version : 2.3.6

Could be the problem. If you used Odin to push the wrong firmware, or put it in the wrong partition, you caused a problem.
