Hi there,
I just changed the PSU for my Pi4 (Rev1.1) from the old official USB-C power supply to the new official 27W PSU for the Pi5. This obviously bricked the Pi4:
When turning on power, the red LED lights up immediately, while the green LED blinks during the first say 500ms, and then also lights up continously. It doesn't matter whether the SD-card is inserted or not. I also tried to recover the Bootloader using an SD-card made with the Pi imager tool. No success. No output on HDMI of course.
When eth is connected, the yellow and green RJ54-leds also light up continously.
I don't want to test this PSU with another Pi and probably destroy it. What to do? Any chance to bring the Pi4 back to life again?
Thank you for any help,
Chris
