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.

It's funny how these days I find BGA reballing a rather soothing and meditative practice instead of a stress factor it used to seem not so long ago 😊.

@RPiSpy this is a complete nonsense - if they were supporting #sustainability and #longevity in order to reduce #ewaste they are generating every day they’d publish the #schematics for the #raspberrypi5 and sell the replacement parts for #electronicsrepair - #da9090, #da9091 and #rp1 chips to begin with.
@cyclical_obsessive Dave looks awesome 👏🏻.
As for the I2C - sadly that’s one more case of failed repairability - too bad #raspberrypi won’t sell their #RP1 chip separately😔.
Hopefully someday @iFixit will help us with this one😉.
For now we can only read about it here:

One more dead Pi 5 - again with a blown #RP1 chip.
Could have been fixed if #RaspberryPi sold parts for #repair.
