Hello there,

Please try to erase ic once. check your hardware fully ( a broken wire, blown device, wrong connection). Also ensure clock circuit too.. use latest version of mplab software

Best regards,

Firstly, do you have a low ESR cap of 10uF attached between Vddcore/Vcap and Vss pins?

Secondly, are all the Vdd/Vss pins appropriately connected? Is the ENVREG pin tied to 3.3v?

Thirdly, which pair of PGCx/PGDx are you using to attempt to program the device? They must be of the same pair.

Also, is the power supply well regulated? What voltage, 3.3v?

Try erasing the flash and rewrite.
some time it happens with failed PicKit, broken wire, blown device. It's the generic return when MPLAB doesn't get the right info back for the device ID
