Digispark ATTiny

Development Tools Uploading
1

I bought 1/2 dozen of these ATTiny development boards to play with and to show my friends how capable an 8 pin MCU can be. My program reads a joystick and displays data on an LCD. Worked on the first one I uploaded, using the Digispark 16.5Mhz board. The program takes up only 42% of available memory. Despite that, I think I overwrote the bootloader and all attempts to restore it using the Google-oracle to help me, I was not able to. Taking a new component, uploading it...worked fine, and then it DIDN'T and I have no idea why not!
So...I abandoned that idea and decided to just upload from a USB programmer. I've used this before, many times for ProMinis without issue. Won't work with ATTiny. For one thing, if I choose Digispark (default) for my board, which it is, I can't choose the programmer - it defaults to Micronucleus. If I choose ATTiny85 with my USB programmer, I get this error:

Upload error: Failed programming: recipe not found 'program.pattern'

I've scoured the Internet for solutions at Arduino and at Digispark, without any success. I could try another programmer or use a Nano, but I see nothing wrong with my current setup.
So...any advice on next step? I've got 4 ATiny dev boards left.

I think you have to disconnect the board before programming, try that.
here is a link to some info http://digistump.com/wiki/digispark

I have found a solution...disregard the boot loader, ie, don't install it. I took a "bricked" ATTiny (Digispark) and programmed it directly with an ICSP programmer and it worked. This works as well, maybe better than plugging the development board into a USB socket. So, I'll use ATTiny ICs instead of the larger Digispark device.
