I just uploaded a sketch to my 3v trinket that tried to use pin 4 as in input, like the trinket example code but using a different (not-a-good-idea) pin.
int display=0;
void setup() {
display=0;
pinMode(4, INPUT);
digitalWrite(4, HIGH);
}
void loop() {
if (display)
{
//do stuff
display=0
}
if (! digitalRead(4))
display=1;
}
It failed to verify on readback, and now when I reset the thing I don't go into the bootloader. Is it bricked?
Did I just brick my Trinket?

Re: Did I just brick my Trinket?
I'm going to answer my own post in case someone else does the same boneheaded thing.
1) It is not bricked!
2) The bootloader did get screwed up! But that's okay!
I was able to fix my trinket using the instructions on this page and a Pro Trinket 3v. I did not have to modify the sketch to work on the Pro Trinket instead of an Uno.
