Samsung GT15503 displaying RAMDUMP MODE(ARM9)

sounds like a job for a technician

press volume+ and power buttons only when powering on, release the buttons after ~3 sec when you see samsung logo.

Hello. Might be that there is no Recovery installed on ur device and surely you can't enter the recovery mode.
first make sure that the Vol -/+ key are really functionable and besides be aware for some tricky when you might recognize the Vol + key needs a little extra pressure for clearly circuit! Maybe, Maybe
You have to try! look out for a flashable recovery for your device and flash it with Odin! I pray you don't use KIES!!! is really easy, u'll quickly find a manual for that via "google". Just to make sure a recovery is present on the Ace. by know hitting the key-combi remind you for keeping the "Power" and "Home" Button pressed until the second Logo appears. The other way could be release the Vol+ key by appear of the first Logo and keep hitting it over to second Logo appear. Sadly it might be keep the Vol+ Button released after first Logo could do the Trick! So...... good luck on give these methods a try!
adb rebooot recovery using pc-connection or "su reboot recovery" on terminal app might be also work for You!
have fun!no pain, no gain *smile

Install clockwork mode recovery using odin .. then go into recovery mode.
