Hello, i got my RPi4 4GB last July together with the offical power supply. It worked without a Problem from the beginning. The problem is after i left it powered off for some months i tryed to boot it up but it wont boot anymore.
things i tried:
- I tryed 3 different SD cards that worked fine on my RPi0w with the newest Raspian.
- Without SD card the RPi’s green LED blinks 4 times, with means the bootloader should be fine
- While booting the Green LED blinks 4 times, then stays on and repeats with 4 blinks etc. on the forum i read that means it cant find the start*.elf, but why should it suddenly be unable to finde that file.
The Pi was always powerd via the offical power supply and was savely tucked away in a case and even had heatsinks and a fan(The RPi4 would get way to hot for my tased otherwise).
So what else could i try? Any ideas?
