If your IMEI and/or serial number are corrupted you're probably out of luck. Changing IMEI and serial numbers is illegal, so phones that appear to have these numbers changed will probably not work. You might be able to use Kies software to completely wipe and factory reset your phone, or perhaps ODIN software if Kies doesn't work.

I wish you the best of luck. I hope you can recover your device and get it working again.

Both are software that need to be installed on your computer. There are instructions with the software and also lots of tutorials online. Just search for them
