Mohamed,
I cannot say this with 100% certainty but usually, Cisco devices allow to downgrade their IOS. Please post the complete transcript of the failed boot attempt. Also add the output of the dir flash: command from the ROMMON. Thanks!
Best regards,
Peter

Post the entire boot up sequence. The IOS you want to run could be corrupted.

I know why you're getting the "Wrong IOS image for the router".
887VA does NOT support IOS version 15.0(1). The lowest IOS you can use for a 887VA is 15.1(3)T or 15.1(4)M.
