Maybe I've already replaced a #RaspberryPi5 CPU before.
But today was the first time I replaced a Secure Boot locked CPU on a Pi 5.
And that's a whole different story - after I replaced a CPU Pi blinked a 1-2 code - "SD card overcurrent detected". Weird.
I tried to restore #EEPROM from a Micro SD - it flashed 3-2 - "SPI EEPROM is write protected".
I soldered another CPU. Same.
I replaced #RP1. Same.
Turns out it was EEPROM.
