create a new tool called, for example, avrdude1
simply copy section tools.avrdude and name it tools.avrdude1
the trick is that we remove switch "-Uefuse:w:{bootloader.extended_fuses}:m" from "tools.avrdude1.erase.pattern="

I just encountered the problem after updating my Arduino IDE to the latest 1.6.0. I followed your instructions and succeeded in uploading to ATMega8 again! Thank you so much!

[Manigandandmx]

Thanks you very much i successfully bootloaded my chips because of your advice.

[rigelinorion]

Thanks. I'm glad I could help.

[nirgos]

Thank you so much! This worked for me.

[ramirovelazco]

This worked for me, with atmega8-16PU
Thanks!
