Catalyst 2950 with boot error

Hi, I have a catalyst 2950-24 and accidentaly uploaded the .TAR file instead of tge .BIN file. I had also, deleted the previous IOS. I try to do an

xmodem and get this error

switch: copy xmodem: flash:c2950-i6q4l2-mz.121-22.EA12
Begin the Xmodem or Xmodem-1K transfer now...
CCC
### Send (x) c2950-i6q4l2-mz.121-22.EA12.bin: NAK on sector

### Send (x) c2950-i6q4l2-mz.121-22.EA12.bin: Retry Count Exceeded

Also, when I try to delete the .TAR file I get permission denied.

Any thoughts?

Thanks

During the ROMmon boot, did you enter the command "flash_init"?
