PIC32MX wrong bootloader

Hello everyone,
 
My name is Petar Milchev and I am working with PIC32MX575F512L processor. 
Unfortunately I upload wrong bootloader (for PIC32MX470F512L) on that chip and now I can't access it.
When I try to connect with MPLAB IPE, it said:
"...
Target voltage detected
Unable to connect to the target device.
Failed to get Device ID"
 
Does anyone have some ideas?
Is there any force boot, or something similar, which will help me to erase the chip and upload the right bootloader?
 
Thanks and Regards,
Petar

    What board is your PIC on?
    A Microchip evaluation board, or something you designed?
     
    What programmer are you using?
    How is it connected to the PIC?

    Hello Ric,
     
    Thank you for the quick response.
    I am using PIC on a custom board. Its used for controlling an audio multimedia.
    We are using PicKit3 for debugging and programming. It is connected throw its serial programming port.
     
    I am wondering, could it be dead? Before I upload the wrong bootloader, it works fine.
    Also I think that two MCUs could be replaced. I mean, that they share almost same pinout, so it couldn't be burned?
     
    So any ideas?

    Even with the wrong boot loader (or any program) you should be able to erase all.

    Hello Ruben,
     
    I also think on that way...
    Well obviously I should replace the MCU with new one.
    Thank you
