Close the Arduino IDE.
Locate and open the avrdude.conf file. It should be located in the {Arduino}\hardware\tools\avr\etc folder.
Make a backup copy of the avrdude.conf file.
Find the ATtiny85 section. It starts with this...
#------------------------------------------------------------
# ATtiny85
#------------------------------------------------------------
Locate the memory lock section. It looks like it starts 134 lines below the start of the ATtiny85 section.
Add "read" data...
memory "lock"
size = 1;
write = "1 0 1 0 1 1 0 0 1 1 1 x x x x x",
"x x x x x x x x 1 1 i i i i i i";
read = "0 1 0 1 1 0 0 0 0 0 0 0 0 0 0 0",
"0 0 0 0 0 0 0 0 o o o o o o o o";
min_write_delay = 9000;
max_write_delay = 9000;
;
Save and close the avrdude.conf file.
Try again.
