The only way to re-enable Reset or SPIEN fuses on some AVR chips like ATtiny13A, to allow them to be reprogrammed, is to use High Voltage programming (HVP) method. This was available on AVR Dragon but since this has been discontinued, there is a lack of suitable programmers.
So, what is now the best solution for AVR High Voltage Programming?

Older versions of Kanda Software will not work with latest FTDI USB driver 2.12.36, released 17/06/2021. This applies to PIC and AVR handheld programmers, AVR keyfob and AVRISP-U programmers.
The solution is to roll back the driver to 2.12.28, released 16/08/2017.

Atmel have stopped making AVRISP-MKII but Kanda sell a Waveshare version that is identical to the original. Atmel Studio fully supports AVRISP-MKII and it is simple to install and use with Studio but it can also be used with AVRDude and Great Cow Basic compiler.

Kanda have released a free Android App, for smart phones and tablets, that lets you update your AVR or PIC handheld programmer contents from your phone. Just load the programmer, copy it to a programmer file (.PRG), send it to your customer, distributor or engineer and they use their phone or tablet to update the programmer.

When AVR microcontrollers were first introduced in 1995, In System Programming was simple, with one programming method (Serial Programming Interface or SPI) and a recommended 5 x 2 10-pin target interface. For 10-15 years, this stayed the same except for the addition of JTAG programming on some devices and a move towards a 3 x 2 6-pin target header. In the last few years, new interfaces have sprouted like weeds, including TPI, PDI and UPDI. What do this all mean and how does it affect you?

The latest versions of Atmel Studio 7 seem to omit External Tools… from the Tools menu. This command is necessary to add your own programmer so it can be launched from Studio. If it is missing, how is it added?
